The method of repair and maintenance of computers and system for its implementation

 

(57) Abstract:

The invention relates to the repair and maintenance of personal computers, namely, to the diagnosis of the health of hardware and software. The technical result is to minimize communication between the faulty computers users and service center for communication channels, reducing the unit cost of software, hardware and other resources. For this purpose apply the updated repair expert system (RES), which contains a database of knowledge about software and hardware and backgrounds and codes for the identifiers of their failures, scripts, diagnosis and repair and KBMS, RES allocate, write on a separate tool storage and distribution of information and is used to diagnose and correct each failure before contacting service center at least one fragment which is sufficient in most cases for Autonomous recovery of the computer when this fragment is necessarily contains ID codes of failures and the means call the service center only code identifiers is not resolved failures. The system performing the above steps, EKB-ly, 1 Il.

The invention relates to the repair, in particular remote service mainly personal computer (hereinafter PC), and more specifically to the diagnosis of health hardware (hereinafter AC) and software (the SOFTWARE) and repair primarily ON.

The invention is used in conditions when the user's computer can run at least using a suitable repair media with appropriate software, or by using an intermediate computer repair, or under the control of the remote service center, provided that this centre by using the specified media or specified repair of computer and between such a centre and a faulty computer user operates at least one communication channel.

It should be borne in mind that in relation to the invention hereinafter indicated:

the term "user computer" - mainly PC, which is characterized by at least one such failure of at least one hardware and/or at least one software tool, which the user cannot identify and/or correct yourself,

the term is of artov software package, which at least contains:

- knowledge base about the AU, knowledge-base, the knowledge base about scenarios diagnosis and repair of computer users, a database of computer viruses and software tools for their detection and neutralization and control system (hereinafter KBMS) these knowledge bases and data, and

- one software tool to connect the faulty computer user ES:

the term "maintenance":

first, automated diagnosis of at least one user's computer to identify the defective blocks of the AU for their current or subsequent repair or replacing and/or identify defective parts,

secondly, automatic or manual restoration of as,

thirdly, mostly automatic recovery of health, and

fourth, install the following temporary "soft caps" for those drivers to hardware or software, with the help of the used fragment RES or existing full RES are not amenable to repair service because:

the reason for this refusal was not known RES on the date of the call,

either the REFs not smone repair service" - at least part of the repair and maintenance of faulty user's computer without the participation of the service center;

the term "repair media" (hereinafter IDH - a hardware tool that in all cases it is necessary and in many cases sufficient for Autonomous repair service computer of the user, by using at least one recorded on the media is functionally isolated fragment RES,

the term "Autonomous intermediate repair computer" (hereinafter APRC) is a hardware tool:

designed for Autonomous maintenance, computer users or by their location (mainly in the local computer network), or at such a distance from the locations specified computers, which is usually substantially less than the distance to the nearest service center, and

which is equipped with at least one suitable IDH, which recorded at least one functionally isolated fragment RES;

the term "standard software" operating systems (hereinafter OS) Windows, Unix, and so on, software packages Microsoft Office, Lotus Smartsuite, etc.,

the term "standard program Teie such test program building blocks and conventional computer peripheral equipment, which are built into the OS,

the term "standard software test software" - programs testing of specialized software tools that are typically built into the OS, or supply to users for a fee firms specializing in the manufacture and installation of the software, and

the term "service center" (in English "HelpDesk", meaning literally "help Desk") is an institution which has a complex of hardware and software, including full RES, and expert personnel that are required for remote maintenance arbitrary computers for systematic improvement of full RES and supplies fragments RES for offline repair and maintenance of computers users. Thus, with respect to the invention, this centre is a provider of IDH and/or APRC equipped functionally separate fragments RES.

It is well known that:

computers, especially PCs today are products of mass production and consumption,

the failure of the AU and/or software on users ' computers often lead to serious economic losses, osobennyh and information resources,

continuous complication, particularly with following operating systems with a graphical interface like Windows, Unix, and so on, significantly outstripping the ability of ordinary users on the practical implementation in full of those opportunities that provide them with increasingly complex operating systems, application software packages,

most average PC users don't know the design of computers and peripheral AU, composition and structure and the principles of cooperation programmes (especially in cases where the individual parts purchased from different manufacturers and installed without proper consideration of their compatibility) and

such users (which, incidentally, is becoming more) during repeated failure to start or run some commands may not be able to recover your computer and need help from the outside.

The need for such external assistance has become very noticeable in the late 80's - early 90-ies of XX century. At the same time were systematized prerequisites failures of computers and developed the first system remote diagnostics (see, for example: 1. Bondavalli et al., "Failure Classification with Respect to Detection", the Future Trends of Dist. Computing Sys, 1990, IEEE Pub. p. 47-53; 2. Griffin, "A fault Diagnosis Prototype For Ethernet LANs", IEE Colloq. 1989, 64: ) physical faults, AU, the most common damage to the boot disk or network equipment,

(2) distortion of the code in the boot sector of the boot drive,

(3) damaged file allocation table (FAT)

(4) failures when running the BIOS (for example, damaged BIOS code, the absence or distortion of the BIOS configuration information stored in the CMOS memory of the computer),

(5) violations of configuration information AC or applied FOR,

(6) the conflict between the individual speakers and/or parts,

(7) damage to files of the OS or application software.

Now not only professionals, but also ordinary users is clear:

most of these prerequisites failures, namely prerequisites(2, 3, 4, 5, 7 and, frequently, 6), often caused by computer viruses that get into computers when users communicate with other users, in particular, with the use of e-mail and the INTERNET,

the most dangerous "fresh" computer viruses as a means of disposal which become available to ordinary users late, and

as to increase the range and complexity of the AU and the total number of failures, for p the device and the communication channels, for example, a telephone line, refer to remote service centers, is growing much faster than the number of sold computers.

This remote repair services are especially useful when the user's computer is located far from centers of civilization" and only when, based on the results of remote diagnosis is possible, relying on professional help, eliminate the cause of detected failures as and/or.

It is obvious that the REFs and the experts of the service centers are forced to diagnose and resolve those failures that actually occur, working with those users that actually exist. Therefore, the ways and means of maintenance, remote service centers of users ' computers must be designed in such a way as to minimize:

the risk of misunderstandings between users of faulty computers, training which is not included in the functions of the service centers, and RES and live experts of any such centre,

communication through the communication channels (traffic) between the affected computer user's and service center, which was abnromal the user, and

unit costs of software, hardware and other crvi was very difficult problem, for the dialogue between a standard user and service center the less productive:

the more complicated case of failure,

the less skilled the user,

the more loaded the communication channel between the computer user and the selected service center and

than large amounts of data must be transmitted over the communication channel in both directions for diagnosis and recovery user's computer.

For example, from US Patent 5367667 known method for remote maintenance of the users ' computers. This method includes:

call an expert service center by phone call to the user, which - to the best of my understanding the problem verbally explain to the expert of your problems and gives information about your computer,

creating on the computer service center of such a program-script, which includes the code files, the information to identify (diagnose) the user's computer, information for remote access to the user's computer, information for remote computer access user data to a computer service center and manual testing (diagnosis),

introduction a computer is the Federal center and the specified user's computer,

load the specified diagnostic program script from the computer service center to the user's computer, then the first computer terminates the connection,

self statement test the user's computer, which creates a log file with a report on the execution of this instruction,

the transfer of the registration file with the specified report from the user's computer to the computer service center,

determining the needs of the user's computer repair,

selection required for repair of software and

fix defective parts.

This process, first, does not provide for the restoration of as and, secondly, usually requires so much time on explaining the nature of the problem to the expert service center and the greater the load of the communication channel, the less qualified the user and the harder the reasons for the refusal of his computer. Therefore, the program is a diagnostic script that creates a computer service center, usually can not provide recovery FOR a single session of remote diagnostics and repair.

Accordingly, in cases where the refusal of the PC on the gas control system I / o (E-BIOS) according to US Patent 5732268.

This (in fact software system E-BIOS includes:

this first part of the code for self-test power-up (POST) and start functions on the user's computer, which contains the code recognition case, when the computer does not turn on, and

this second part of the code that failed launch connects the user's computer to a remote service computer.

Then the kernel master-code-service computer is automatically loaded in the slave core storage device, random access of the user's computer and provides mostly in automatic mode access to the storage devices of the computer user, correction stored in the computer codes and data and restart after such a repair.

Exclude the user from sharing information with expert service center should facilitate the recovery of the user's computer. However,

built-in E-BIOS detection system background of the failure actually monitors only codes of failures when performing self-test power-up (POST) the main BIOS of the computer user,

accordingly, E-BIOS detects only such ed the CA user's computer, but does not identify prerequisites frequent cases of so-called "hang-UPS" that can be caused by defects and conflicts speakers and/or,

the communication channel between the computer user and the service center because of the need to transfer the kernel master code and other necessary information loaded during the entire session remote diagnostics and repair, and finally,

the extension software package BIOS itself can be a source of failures due to possible conflicts with the latest versions of the OS with built-in graphical interface.

More functionality the system offers repair service ON your users ' computers, which feature such speakers as a network device. This system is according to US Patent 5673386 involves not only the identification of faults and their classification according to the "severity" and the prerequisites to generate fault messages, taking into account the aforementioned characteristics and the transmission of such messages to a remote service center through the available communication channel.

However, even when using such systems, the communication channel between the computer user and the service center will be downloaded during the whole session is done the computer with a live expert service center.

Therefore, the most promising methods of repair and maintenance of computers and such devices for their implementation, which include in their composition Racy.

Among them the present invention to the technical nature of the closest method and system which are known from US Patent 5983364.

The known method of repair and maintenance of computers based on the use of RES, which at least contains a database of speakers, database SOFTWARE, database scripts and diagnostic and control system specified database, which includes at least one means for connecting the specified RES to the faulty computer user. This method typically involves the following steps:

a) identifying at least one failure of the computer which the user is unable to resolve,

b) a direct connection from the user's computer to the RES through the communication channel,

C) at least a single remote sensing AC and which is equipped with a faulty computer, using the specified RES and identifying at least one hardware or software damage which caused the failure,

g) remote controller with many brand is entirely eliminate, and/or

d) remote as the elimination of the detected failure of the software and, if necessary,

e) possible repeating operations (a), (b), (C), (d) and (e) until success or until interrupts repair service.

Accordingly, the system for implementing the described method has a service center, which at least has:

at least one block of non-volatile memory for permanent storage full RES;

the Executive unit, which is electrically connected to at least one specified block of non-volatile memory and is equipped with at least one tool that is intended for direct connection faulty computer users to RES through a suitable communication channel, and

the unit of analysis and temporary storage of the results of the repair and maintenance of users ' computers, which is electrically connected to at least one specified block of non-volatile memory and the specified Executive of the block.

This method and this system is quite convenient for remote repair and maintenance of computers. Indeed, extensive RES allows you to:

significantly reduce the need for dialogue between the user neispravnosti features of the repair service.

However, each call to the service center between your computer and the RES is a continuous exchange of complete data about the failure of the AU and ON and complete data about the tools fault. Therefore, the time spent on maintenance will be greater than the harder the premise of each individual failure and more failure will be detected when the user accesses the service center.

Further, in terms of systematically increasing congestion of communication channels even call the service center can be difficult and time-consuming. Considering the fact that you know the REFs should be invoked at each failure, the user is not able to resolve each such call additionally increases the workload of the communication channels and the unit cost of software, hardware and other resources for each case repair service.

The basis of the invention is by improving repair expert system and its use to create this method of repair and maintenance of computers and such a system for its implementation, which would be able to:

to minimize the communication between the faulty computers PE the cost of software, hardware and other resources for each case repair service.

This problem is solved by the fact that in the way of repair and maintenance of computers, which is:

based on the use of RES, which at least contains a database of hardware, database tools, database scripts and diagnostic and control system specified database, which includes at least one means for connecting the specified RES to the faulty computer user, and

includes the following operations:

a) identifying at least one failure of the computer which the user is unable to resolve,

b) connecting the user's computer to the REFs,

C) at least once a diagnosis of SA and ON, which include the user's computer, using the specified RES and identifying at least one hardware or software damage which caused the failure,

g) elimination of the detected failure of hardware or recommendations to the user on his own elimination, or

d) elimination of the detected failure of software tools and, when the necessity is I,

according to the invention

(1) for repair and maintenance of computers to generate and apply this regularly updated RES, which in General contains:

(1.1) the knowledge base of hardware that exist at the date of the last update of the specified RES, i.e.:

a) data about the classes, types, designs, functionality and driver support for the AU, which are used in computers, and ID codes that are assigned to each of the speakers

b) data on the manufacturers of the existing speakers about the current availability of individual speakers on the market and the possibilities for equivalent replacement of the failed AC some manufacturers fit the same type of speakers of other manufacturers and ID codes that are assigned to manufacturers existing speakers

C) information about assumptions and estimates failures AC and ID codes such assessments emitting code identifiers "critical" failures, which should be eliminated recovery of users ' computers, codes and identifiers of failures, which can be temporarily neglected,

g) library programs test the speakers, which includes at least the standard prograni use the failed AC;

(1.2) the knowledge base about existing on the date of the last update of the specified repair expert system, that is:

a) data on the types and capabilities of at least the existing standard tools and ID codes that are assigned to each of them,

b) information about assumptions and the failure modes and ID codes of failures of individual funds with allocation of codes that identify critical failures, which should be eliminated recovery of users ' computers, codes and identifiers of failures that temporarily can be neglected, and

C) software tools needed to diagnose and repair a corrupted software on users ' computers, which include a library of software testing at least standard, at least one recovery program such software and at least one program is mostly automated call service center with your computer user with an ID-identifier of the faulty software;

(1.3) a database of computer viruses and software tools for their identification and Eoba to work on the desire in the automatic and interactive modes;

(2) before applying this RES for the repair and maintenance of computers emit at least one functionally isolated fragment that includes at least one program is mostly automated call service center with your computer user in identifying at least one failure of hardware or software that cannot be resolved at independent repair service using only the specified fragment RES and without the removal of which is essential to the recovery of the specified computer, despite the fact that this program provides for the transfer to the service center only code identifiers related to each failure is not resolved;< / BR>
(3) record the selection RES on a separate storage medium and outputting information, which deliver or provide the use of at least one such computer user who wants to subscribe to the services of the service center; and

(4) after identifying at least one of the specified failure carry out Autonomous maintenance of the specified defective computer in the measure of the opportunities provided by botopoulos specified computer, either connect it to the service center through the communication channel and continue maintenance with the help of this centre, which is equipped with full RES.

This method allows you to:

first, move the main time to repair service directly on the affected computers users,

secondly, drastically limit the exchange of data between the user of the faulty computer and a service center and, accordingly, reduce the unit cost of software, hardware and other resources for each case repair service.

Indeed, only in some (actually quite rare) cases when offline repair service is unable to resolve the failure of any hardware and/or software on the affected user's computer, which was abnromal services of the service center and got to use the specified selection of REFs. If such an incident did happen, then through the communication channel to the service center receives only the codes identifiers, which are not resolved denial and the choice of which does not depend on the knowledge and skills of the user.

So full RES as part of the service t with significantly less, than usual time and at a lower loading its own hardware and software repair computer user.

The first additional difference is that the selection of REFs at least contains:

a) data about the classes, types, designs, functionality and driver support for the AU, which are used in computers, and ID codes that are assigned to each of the speakers

b) a library of standard programs test speakers

C) recommendations to users on repair, replacement, or temporary cessation of use of the failed AC;

g) data on the types and functionality of the existing standard tools and ID codes that are assigned to each of them,

d) ID codes of the failure of standard tools FOR allocating codes that identify critical failures, which should be eliminated recovery of users ' computers, codes and identifiers of failures, which can be temporarily ignored, and

e) at least one test program at least standard,

W)modestino automatic call service center with your computer user in identifying at least one failure of hardware or software, which cannot be resolved at independent repair service using only the specified fragment RES and without the removal of which is essential to the recovery of the specified computer, despite the fact that this program provides for the transfer to the service center only code identifiers related to each failure is not resolved.

These fragments RES so small in volume that you can burn even on standard floppy disks and promptly provide by mail for offline maintenance, faulty computers any subscribers remote service centers. However, even these fragments RES enough for effective Autonomous maintenance in a typical failures of hardware and/or software.

A second difference is that the selection of REFs at least contains:

(1) part of the knowledge base about AC, that is, at least:

a) data about the classes, types, designs, functionality and driver support for the AU, which are used in computers, and ID codes that are assigned to each of the speakers

b) information about assumptions and estimates the importance of which it is impossible to restore the health of computer users, codes and identifiers of failures, which can be temporarily neglected,

C) a library of standard programs test the AU and

g) recommendations to users on repair, replacement, or temporary cessation of use of the failed AC;

(2) part of the knowledge base current, that is, at least:

a) data on the types and functionality of the existing standard tools and ID codes that are assigned to each of them,

b) information about assumptions and the failure modes and ID codes of the failure of standard means FOR emitting code identifiers "critical" failures, which should be eliminated recovery of users ' computers, codes and identifiers of failures, which can be temporarily ignored, and

C) software tools needed to diagnose and repair a damaged standard software on users ' computers, which include a library of software testing, at least one restoration program of the software and at least one program is mostly automated call service center with computerroutines viruses and software tools for their detection and neutralization and

(4) the control system specified parts of the knowledge bases and the specified database, which is capable of wishes in the automatic and interactive modes;

(5) at least one program is mostly automated call service center with your computer user in identifying at least one failure of hardware or software that cannot be resolved at independent repair service using only the specified fragment RES and without the removal of which is essential to the recovery of the specified computer, despite the fact that this program provides for the transfer to the service center only code identifiers related to each failure is not resolved.

This is significantly larger fragment of the RES allows to significantly extend the capabilities of Autonomous maintenance, remote service center failed to users ' computers. It can be recorded and provided to them or such higher capacity compared to floppy disks, removable media, CD-ROM, memory chips such as FLASH and portable drives with HDD is utero, that it is expedient to equip the individual computers in local area networks, or intermediate service computers, which can be installed one per group of geographically close local computer networks.

The third additional difference is that in full RES and at least one selected from it functionally isolated fragment include stub, which celebrate the failures of hardware or software not provided by the specified system or separated from it by the slice, and fix such plugs in each report on the diagnosis and repair of each defective computer for further analysis and correction of failures. Thereby fails:

first, to overcome the limitations of diagnostic and repair capabilities minimal fragments RES compared to its intermediate fragments and intermediate fragments in comparison with full RES and,

secondly, to identify the types of hardware failures or software Troubleshooting which were not provided for full RES on the date of its last update, so live experts systematically perfections who their computers, which has a service center, comprising:

at least one block of non-volatile memory for permanent storage full RES;

the Executive block. which is electrically connected with the specified at least one block of non-volatile memory and is equipped with at least one means for connecting the faulty computer users to RES, and

the storage unit structured in terms of the types of failures of the software diagnostics and repair service, computer users, which is electrically connected to the specified unit non-volatile memory and the specified Executive of the unit,

according to the invention

a) it further comprises at least one separate tool storage and distribution of information,

b) this tool contains a record of at least one fragment of the RES, which is required for pre-treatment to the service center of the Autonomous maintenance, faulty computer users and call the service center only in case of failure, which is unrecoverable using the specified fragment,

this medium is supplied or provided for the use of at least one takimoana in the comments to a brief description of the method the allocation of RES functionally separate fragments and their provision users for offline repair and maintenance of computers that are removed from service center, dramatically reduces the exchange of data between the service center and faulty computers and reducing the cost of their repair service.

The first additional difference is that this tool storage and distribution of information represents a preferably replaceable repair the media, which, according to the second additional difference selected from the group consisting of a standard floppy disk, or ZIP disk, or CD-ROM, or memory chips such as FLASH or portable hard drive magnetic disk.

The third additional difference is that specified a separate tool storage and distribution of information represents Autonomous intermediate repair a computer that has at least one private block of non-volatile long-term memory, its own Executive unit own unit of analysis and storage of the results of the repair and maintenance of users ' computers, which is electrically connected , who own the means to connect to the communication channels and which is located between the service center and remote from the center of the computers and users:

a) according to the fourth additional contrast, represents a mini-computer, which is electrically connected to the at least one computer of the user, or

b) according to the fifth additional contrast, represents an intermediate service computer, which is located between a service center and a group of geographically close to users ' computers.

Specific advantages such differences will become apparent from the following detailed description of this system.

Expert it is clear that the choice of specific embodiments of the invention any combination of these additional differences from the basic inventive concept and that are described below are preferred examples of its embodiments in no way limit the scope of the invention.

Further, the invention is illustrated by a detailed description of the system and method of repair and maintenance of computers with reference to the accompanying drawing, which shows a block diagram of the entire system.


at least one block of 2 non-volatile memory for long-term storage regularly updated full RES;

Executive unit 3, which is electrically connected to at least one specified block 2 non-volatile memory and

unit 4 analysis and storage of the results of the repair and maintenance of computers 5 users, which is electrically connected to at least one specified block 2 non-volatile memory and the specified Executive of the block 3.

For the connection of RES to the faulty computers 5 users Executive unit 3 is equipped with at least one means 6, which includes at least one of the following means, namely:

a) is preferably replaceable repair media 7 (IDH 7) information, such as a standard floppy disk, or ZIP disk, or CD-ROM, or a memory chip such as FLASH or portable hard drive magnetic disk, and/or

b) Autonomous intermediate repair computer 8 (APRC 8), which is located between the service center 1 and remote from the center of the 5 computers users and which is not shown on the drawing:

at least one private block ene is nnogo service users ' computers,

own Executive unit,

own unit of analysis and storage of the results of the repair and maintenance of computers 5 users, which is electrically connected to at least one specified block of non-volatile memory and the specified Executive of the block and, optionally,

own tool to connect to the channels 9 links, and/or

already mentioned channel 9 (for example, telephone) connection.

This APRK 8 can be made:

a) as a mini-computer, which is electrically connected to the at least one computer 5 of the user (and, in particular, is built into the computer 5), or

b) as an intermediate service computer, which is located between the service center 1 and a group of geographically close computers 5.

IDH 7, APRC 8 are the means for recording, storage and distribution (use) outside of the service center 1 at least one such functionally separate fragment RES, which is designed for Autonomous maintenance, some remote from the service center 1 computer 5 in any case, when the user will find at least one failure of at least one hardware and/or software is Amantea service provided that the computer is defective 5 operable own Central processor and at least one suitable drives or ports, and

APRC 8 can be used even in cases of failure of the Central processor of a computer 5 and/or the means of its connection to the channel 9 communications.

Repair 7 media information and/or APRC 8 may be provided directly by visiting the center 1, or by mail to those users that are remote from the service center 1 computer 5, which was absorbale services center 1.

Service center 1 can be connected through channels 9 to 5 computers either directly or through APRC 8 not shown in the drawing modems or functionally similar devices such as digital DSL or ISDN adapters, which are equipped with such computers 5, APRC 8.

Autonomous maintenance of computers 5 using APRC 8 can be performed regardless of the service using IDH 7. However, it is preferable that the user in identifying at least one failure, which they are unable to resolve, consistently used initially specified IDH 7 and then these APRC 8.

is according to the invention.

In the most General form of such a method includes:

first, the creation and application at the service center 1 is systematically updated interactively involving live experts full RES,

secondly, the selection in such a RES of at least one functionally separate fragment, which is sufficient for Autonomous repair service: for the diagnosis of failures at least standard hardware and software, to fix at least such hardware failure, which is caused by damage to the drivers support the AU, violations of configuration information speakers and the conflicts between different parts of the AU, and to eliminate bounce means at least of the standard software, despite the fact that in the specified fragment RES every failure has its own code-ID, intended for transmission to the service center 1, if the detected fault is not resolved at independent repair service;

thirdly, write at least one such fragment RES (usually by the user of any computer 5) suitable IDH 7 and/or in the unit's non-volatile long-term memory of APRC 8,

in-CV 5, who would like to subscribe to the services in the service center 1, which has a full RES,

fifth, the primary use of at least one such fragment RES for Autonomous maintenance is also faulty computer 5, the user will identify at least one such failure of hardware and/or software, which he is not able to resolve, and,

Sixthly, the request to the service center 1 only after you have identified the inability to resolve at least one identified failure using at least one functionally separate fragment RES, if that service center 1 receives only the ID codes assigned to each failure is not resolved.

Referred to full RES, as a minimum, contain:

(1) the knowledge base of hardware that exist at the date of the last update of the specified repair expert system, that is:

a) data about the classes, types, designs, functionality and driver support for the AU, which are used in computers 5, and ID codes that are assigned to each of the speakers

b) data on the manufacturers of the existing speakers on the current matching of similar speakers from other manufacturers and ID codes, assigned to manufacturers existing speakers

C) information about assumptions and estimates failures AC and ID codes such assessments emitting code identifiers "critical" failures, which should be eliminated restore the health of the computers 5, codes and identifiers of failures, which can be temporarily neglected,

g) library programs test the speakers, which includes at least the standard program of the specified test, and

d) recommendations to the users on the replacement, repair or temporarily stop using the failed AC;

(2) knowledge-base, existing on the date of the last update of the specified RES, i.e.:

a) data types and functionality, at least the standard of existing tools and ID codes assigned to each of them,

b) information about assumptions and the failure modes and ID codes of failures of individual funds with allocation of codes that identify critical failures, which should be eliminated restore the health of the computers 5, codes and identifiers of failures that temporarily can be neglected, and

C) is komputerach 5, which include a library of software testing at least standard, at least one recovery program and at least one program is mostly automated call service center with your computer 5 of the user with an ID-identifier of the faulty software;

(3) a database of computer viruses and software tools for their detection and neutralization and

(4) the system of management of these knowledge bases and the specified database, which is capable of wishes in the automatic and interactive modes.

Further described in REFs isolated and used for Autonomous maintenance, faulty computers 5 at least one functionally isolated fragment. This fragment, as a minimum, contain:

a) data about the classes, types, designs, functionality and driver support for the AU, which are used in computers 5, and ID codes that are assigned to each of the speakers

b) a library of standard programs test speakers

C) recommendations to users on repair, replacement, or temporary cessation of use of the failed AC;

d) ID codes of the failure of standard tools FOR allocating codes that identify critical failures, which should be eliminated restore the health of the computers 5, codes and identifiers of failures that temporarily can be neglected, and

e) at least one test program standard,

g) at least one restoration program standard and

C) at least one program mainly automatic call APRC 8 or the service center 1 from the computer 5 when detecting at least one failure of hardware or software, without the removal of which it is impossible to restore the health of the computer 5, despite the fact that this program provides for the transfer of APRC 8 or service center only 1 code ID of each damaged hardware or software that is not amenable to repair or restore using the used fragment RES.

For recording and delivery of the specified minimum fragment RES at least one user computer 5, which wants to subscribe to the services of the service the Dean IDH 7. It should be noted that in our days for recording, storing and Autonomous repair and maintenance of computers 5 using the described minimum fragment RES as IDH 7 preferred floppy disk, because:

first, all existing computers 5 have at least one drive for the discs

secondly, these drives are practically insensitive to failures of major systems of the 5 computers, and therefore if you cannot run any computer 5 running your own hard disk and/or CD-ROM, you can usually start it by using the floppy disk, and,

thirdly, the capacity of even a single floppy disk in most cases, it helps to write such a minimal fragment of the RES, which is able to restore the functionality of the computer 5 when the most frequent failures, except for Troubleshooting AC type physical damage boot disk or network equipment. However, in this case, the minimum fragment RES is able to prompt the user for corrective action failure.

When detecting at least one failure, the user is unable to resolve specified IDH 7 is introduced into the corresponding the wow repair service as far as possible, provided is used by the fragment RES.

It is an Autonomous repair service includes:

a) at least one examination of the AU and that comes with the computer is defective 5, using the minimum fragment RES, and identifying at least one hardware or software damage which caused the failure,

b) elimination of the detected failure of hardware or recommendations to the user on his own elimination, and/or

C) elimination of the detected failure of the software and, if necessary,

g) possible repeating operations (a) and/or (b) and/or (C) using the same or different IDH 7 to success or to establish the impossibility of complete repair using the selected minimum fragment RES.

In the latter case, the minimum fragment REFs or after the "discussion" results test and repair with the user connects the computer 5:

or to the nearest APRC 8 to continue Autonomous maintenance, using a larger fragment RES,

or to the service center 1 through the channel 9 communications and owned by this centre 1 unit 4 anantnag service with full RES, which is stored in block 2 of the non-volatile memory.

From the above description Autonomous repair service clear:

that APRK 8 or to the service center 1 receives information only about a collection of code identifiers that relate to the failure is not resolved by using the (minimum) fragment RES, which was recorded on IDH 7,

what maintenance level APRC 8 or the service center 1 also involves working until success or to interrupt the current communication session with a faulty computer 5 to refill the RES involving living experts.

A better way Autonomous repair and maintenance of computers 5 provides for the allocation of RES service center 1 and installation of the at least one APRK 8 at least one more extensive functionally separate piece which hereinafter for convenience abbreviated as indicated by the phrase "intermediate fragment and which typically contains:

(1) part of the knowledge base about AC, that is, at least:

a) data about the classes, types, designs, functionality and driver support for the AU, which are used in computers 5, and ID codes, which p the estimates emitting code identifiers "critical" failures, which should be eliminated restore the health of the computers 5, codes and identifiers of failures, which can be temporarily neglected,

C) a library of standard programs test the AU and

g) recommendations to users on repair, replacement, or temporary cessation of use of the failed AC;

(2) part of the knowledge base current, that is, at least:

a) data on the types and functionality of the existing standard tools and ID codes that are assigned to each of them,

b) information about assumptions and the failure modes and ID codes of failures of individual funds with allocation of codes that identify critical failures, no problems that you cannot repair computers 5, codes and identifiers of failures that temporarily can be neglected, and

C) software tools needed to diagnose and repair a damaged standard on the 5 computers that include a library of software testing, at least one recovery program and at least one program mainly automatically cause the BR> (3) a database of computer viruses and software tools for their detection and neutralization and

(4) the control system specified parts of the knowledge bases and the specified database, which is capable of wishes in the automatic and interactive modes.

This intermediate fragment RES can be used, as described above, for offline repair and maintenance of computers 5 or directly after identifying at least one failure of any computer 5, which you cannot resolve, or after preliminary minimum fragment RES IDH 7.

From the above it is clear that during recovery using intermediate fragment RES repair service computer 5 stop, and when it is impossible to eliminate at least one failure of the computer 5 through the channel 9 communications to connect to the service center 1 and continue maintenance with full RES to success or to establish the need to Supplement RES.

It is also clear that in this case, the service center 1 receives information only about a collection of code identifiers, Koti, the selection of intermediate fragments RES for offline repair and maintenance of computers 5 is particularly useful when groups of these 5 computers connected in a local network, and the better economically than more computers 5 are included in this group.

It is clear that recorded on IDH 7 or APRC 8 fragments RES advisable to periodically update using the selected service center 1, which has a full systematically updated RES.

In conclusion, it should be noted:

all prerequisites and types of possible failures cannot be a priori possible when creating a full RES and

the number of faults that can be diagnosed and corrected using fragments RES, usually the smaller, the smaller the selection.

Therefore, as part of the full RES provide and allocate of these fragments typically include so-called "stub". They say the hardware or software of any specific computer 5, the failure of which could not diagnose and/or resolve with the help of the used fragment RES or even the REFs in General. Same plugs note unidentified hardware sludge is a fragment.

Data about the used caps lock in reports about repair service throughout the chain "(IDH 7) - APRC 8 service center 1" for further analysis and, if necessary, to improve full RES and clarification of its working parts.
