The invention relates to communication technology, namely the restoration of mobile communications in the field (in emergency situations).

Interpretation of terms used in the application for the alleged invention.

Recovery is a complex of works on the identification of failure determination of its location and nature of mobile communications equipment, maintenance and monitoring of their technical condition (GOST 27.002-89. Reliability in engineering. Terms and definitions. - M.: Publishing house of standards, 1989. - 37 S.).

Repair of a complex of operations on transfer of mobile communications from an unhealthy state to a healthy (GOST 18322-78. The system of technical maintenance and equipment repair. Terms and definitions. - M.: Publishing house of standards, 1978. - 14 S.).

Mobile communication means, communication means, mounted on the means of mobility and designed for education typical transmission channels and group paths of the primary network connection. To consider in the invention means of communication types include: radio relay, tropospheric, radio, space and wire (basics of building systems and networks transmission media. Textbook for high schools / VCI, Aigialos, Cvetek, Vmmain; under. edit Vmmain): Hot line - Telecom, 2005. - 382 S.).

The technical control is the first state - determining actual values and (or) qualitative characteristics of the technical condition of the communication means, comparing them with the requirements of normative-technical documentation, to assess the technical condition of means of communication (GOST In 25883-83. Maintenance and repair of military equipment. Terms and definitions. - M.: Publishing house of standards, 1983. - 19 S.).

Repair body (RO) - a set of interrelated documents, tools, repair and performers (repairmen)necessary to restore communications (GOST 25866-83. The operation of equipment. Terms and definitions. - M.: Publishing house of standards, 1983. - 10 seconds).

Technical readiness - the ability of communication to perform its required function at any time when the presence in its composition of the required number of working nodes (blocks, items) with the necessary supply of a resource contained in the original set of operational documentation, the status or condition, and trained to perform assigned tasks (Grecinieku E.V., labunets A. M., Belov A.S., Lyubimov, VA, Pominchuk O.V. Development of scientific and technical solutions to ensure technical readiness of the elements of the information-telecommunication network based on the method of functional diagnostics / telecommunications No. 8, 2005. the.22-24).

The repair operation - communications-finished part of the repair that represents a set of techniques that are performed on a single workstation installed for the operation being performed by means of repair (GOST 18322-78).

Maintenance - technical devices, spare parts and materials for repair of telecommunications equipment (GOST In 25883-83).

The aggregate method of repair is an impersonal method of repair, which failed units are replaced or renovated in advance (GOST 18322-78).

Under the Assembly refers to the Assembly unit, having the properties of full interchangeability, independent of the Assembly and perform a specific function in products for various purposes (e.g., motor) (GOST 18322-78).

A detailed method of repair - repair method, which replaces or restores individual parts, replacement (GOST 18322-78).

Failure is an event consisting in the violation of the operating state of the means of communication (GOST 27.002-89).

Electronic functional unit - radio electronic means (RECs)representing a functionally complete Assembly unit, performed on a supporting structure that implements the transformation function of the signal and not having an independent operational use (GOST 26632-85. Levels resoucres the Deposit of radio-electronic means according to the functional and structural complexity. - M.: Publishing house of standards, 1985. - 10 seconds).

The main task in the field (in case of emergency) is carrying out activities to maintain communications in the state, providing the required technical readiness, the main of which is the repair. While repair of the means of communication is hardware technical support (ATO). Known systems repair mobile (field) communications based on ATO (maintenance of means of communication. Part I. Pijarska, Alagille, ACI / edited Alacrastore. - L.: YOU, 1980. - 302 S.; maintenance of tools and communication systems / edited Alacrastore. - L.: YOU, 1979. - 180 S.; maintenance and reliable communications. Alagille, Wphkloio, Bccoming. - L.: YOU, 1970. - 278 S.).

The way the organization of repair in such systems suggests that ATO is the repair of various equipment (receivers, transmitters, power supply, antenna-feeder devices and other) only one type of means of communication (radio, radio-relay, tropospheric, space, wired). This way the organization of repair is most effective when the diagnosis and repair for a large number of similar means of communication.

However, in an emergency, communication is used a limited number of diverse means of communication. An example is the sing of a limited number of diverse means of communication in emergency situations described in (Bulgak V.B. have been, Varakin LE, Krupnov AU and other basic management communications of the Russian Federation / Under the editorship Varakin LE, Krupnova AU - M.: Radio and communication, 1998, RES, p.93).

When using diverse means of communication, you must have the ATO for each media type that leads to an increase in the number of ATO and reduce the effectiveness of the repair, which is manifested in increased downtime rate (lower load factor repairmen).

Known closest to the claimed (prototype) in its technical essence is a method that is implemented in an automated system for monitoring and diagnostics (the Invention of "Automated control and diagnostics", patent RU 2257604 C2, G05 23/02, NV 17/00, publ. 27.07.2005, bull. No. 21). The way the prototype is in control of the instrument, in this case before the control node of electronic equipment (REE) is connected to an automated system for monitoring and diagnosis, is retrieved from the database control program, including benchmarks, is the issue of test signals, this sets the tone settings of the special form (to control analog and analog-to-digital circuits and high-frequency signals (for control nodes REA containing high-frequency part), the control procedure is performed in stages (steps), and the synchronization of IP is of regular supply test signals and measuring the response signals provided by the clock supply signals of a given frequency from the programmable synchronization unit, and the control sequence of the issuance of the test signals provided by the measurement of the response signals and comparing them with a reference is made under the program under control of the control computer complex, collectively supplied to the node REA control reference test signals receive a combination of measured parameters of the response signals, which are compared to reference values of the response signals, when the measured signals are within tolerance nodes REA be considered fit, when the parameters of the measured signals for the tolerance zone is given fault message this node REA and the need for diagnosis of faults; diagnose faults, while on the host computer sets the type of diagnosable node REA, from the database retrieved program diagnosis, including a set of sequentially-issued diagnostic tests, the diagnosis process is performed in stages, the first stage in the site are served diagnostic tests, allowing you to pre-locate faults in the schema node, after the preliminary localization of the point of refusal is to drill the point of refusal, to this end according to the program of diagnostics issued instructions for the connection of measuring devices in the appropriate prom is mediate point of the circuit, based on the analysis of parameters of signals received with use of measuring instruments identified problems or issued clarification on a similar analysis of other portions of the electric circuit node, the measurement process signals in the intermediate points of the site and the subsequent comparison with the corresponding parameters of the reference signals for the same points continues until a complete diagnosis of the entire circuit node, a sequence view of the intermediate circuit node is set based on the characteristics of the build site, and also taking into account the principle of operation of the node, based on the results of the diagnostic repair node REA (elimination of detected errors), then re-inspected the repaired node REA specified above, if the control is successful, the node REA admits fit (refurbished)if you set the deviation from the reference characteristics, which means that an open fault, the node REA re-runs diagnostics to identify unresolved fault, the repair process and control ends when the node CEA is recognized as valid.

The main disadvantage of the prototype is that when a large number of diverse communications needs to have a large number of diverse ATO, th is leads to an increase in the number of ATO and reduce the effectiveness of its functioning, expressed in increased downtime rate (lower load factor repairmen). Thus there is no possibility of simultaneous diagnosis and repair multiple (heterogeneous or homogeneous) communications (Technical operation means, movable objects and communication structures / edited Alacrastore. - M.: Voenizdat, 1974. - 302 C.). In the prototype is the ability to diagnose only the individual electronic units to the presence in them of the reasons for failure, but not the means of communication in General, and there is no possibility to diagnose communication as a complex object, consisting of various equipment, which does not allow to implement the aggregate method of repair as the most promising in the field (ES) (maintenance of means of communication. Part I. Pijarska, Alagille, ACI / edited Alacrastore. - YOU, 1980. - 302 S.).

The technical result of the invention is to develop ways to build a mobile repair body communication that extends an existing method, as well as having higher compared with existing methods, the efficiency by reducing the downtime rate (increasing load factor) repair and reducing the number of jobs in the ATO, including the possibility of the ability to diagnose communications in General, as a complex object that consists of a combination of electronic units, is realized in this aggregate method of repair, as the most promising in the field (emergency).

This technical result is achieved by the fact that the proposed method of constructing a mobile repair body communication means different from the famous diagnose and aggregate repair at the same time as several homogeneous and heterogeneous mobile communications in the field, based not on the type of these means of communication (radio, radio-relay, tropospheric, space, wired), and the type of equipment repair communication equipment (receivers, transmitters, power supply and antenna-feeder devices and others belonging to different media types). While repair various types of equipment are carried out in one repair the body. Thus, the proposed method will allow more efficient to organize the repair of different types of mobile communications while reducing the number of jobs in repair the body and increase the load factor of repair in case of emergency.

The analysis of the level of technology has allowed to establish that the analogs are characterized by the sets of characteristics is identical for all features of the claimed invention, are absent. Therefore, stated the Lenna invention meets the condition of patentability "novelty".

Search results known solutions in this and related areas of technology in order to identify characteristics that match the distinctive features from the prototype features of the claimed invention, have shown that they do not follow explicitly from the prior art. Of certain of applicant's prior art there have been no known impact provided the essential features of the claimed invention to the achievement of the technical result. Therefore, the claimed invention meets the condition of patentability "inventive step".

"Industrial applicability" method due to the presence of elemental basis, on the basis of which can be performed by devices that implement this method.

The claimed method is illustrated in the drawing, which shows a scheme of work the repair of the body.

The proposed method consists in the following.

The first step is to connect N diagnosed communications to repair the body. Further communication received on 1,...,n workplace (RM). Here you define the type of communication is chosen from 1 to m program diagnosing means of communication depending on its type, species identification of failed equipment, conducting diagnosis of a failed equipment. Following is the aggregate repair among the STW communications depending on their priority (importance).

The procedure of the proposed method consists in the following: before the control node of electronic equipment (REE) is connected to an automated system for monitoring and diagnosis is the identification (definition) type of communication means, connected to repair the body. Identification of authors known to specialists procedure implemented by a number of known algorithms (Shikin. Neural network: a complete course, 2nd edition. TRANS. from English. - M.: Publishing house "Williams", 2006. - 1104 S., p.115-116), technical devices (Metrology, standardization and measurements in communications technology: Textbook. manual for schools / Bchamel, Aventino, Alienesque and others; Ed. by Bphome. - M.: Radio and communication, 1986. - 424 S., RIS, p.362, RIS, str) and schemes of dimension (Isivuno, Lyubimov, VA, Sudakov A.N., Labunets A.M., Grecinieku E.V. Methods and means of measurement in telecommunication systems: a Handbook. Eagle: the Academy of the Federal security service of Russia, 2008. - 220 C., RIS-3.14, p.60-67). According to the results of identification of the means of communication chosen program of diagnosis, depending on the type of the connected communication tools, diagnostics equipment, means of communication, namely, that from the database is retrieved by the control program, including benchmarks, is the issue of test signals, when et is m are the parameters of signals of a special form (to control analog and analog-to-digital circuits and high-frequency signals (for control nodes REA, containing high-frequency part), the control procedure is performed in stages (steps), and the synchronization of sources of supply test signals and measuring the response signals is provided by applying a clock signal of a given frequency from the programmable synchronization unit, and the control sequence of the issuance of the test signals provided by the measurement of the response signals and comparing them with a reference is made under the program under control of the control computer complex, collectively supplied to the node REA control reference test signals receive a combination of measured parameters of the response signals, which are compared to reference values of the response signals, when the measured signals are within tolerance nodes REA be considered fit, when the output parameters of the measured signals for the tolerance zone is given fault message this node REA and the need for fault diagnosis of, from the database is retrieved, the program diagnosis, including a set of sequentially-issued diagnostic tests, the diagnosis process is performed in stages, the first stage in the site are served diagnostic tests, allowing you to pre-locate faults in the schema node, after pre-Loka is Itachi the point of refusal is to drill the point of refusal, with this purpose, according to the program of diagnostics issued instructions for the connection of measuring devices at corresponding intermediate points in the circuit, based on the analysis of parameters of signals received using measuring instruments identified problems or issued clarification on a similar analysis of other portions of the electric circuit node, the measurement process signals in the intermediate points of the site and the subsequent comparison with the corresponding parameters of the reference signals for the same points continues until a complete diagnosis of the entire circuit node, a sequence view of the intermediate circuit node is set based on the characteristics of the build site, and also taking into account the principle of operation of the node, based on the results of the diagnostic repair node REA (elimination of detected errors), then re-inspected the repaired node REA as indicated above, if the control is successful, the node REA admits fit (refurbished)if you set the deviation from the reference characteristics, which means that an open fault, the node REA re-runs diagnostics to identify unresolved fault, the repair process and control ends when the node CEA is recognized as valid, then PR is taken off, the prediction of the technical condition of communication. Forecasting technical condition of communication is based on a combination of measured parameters of the response signals by the control program. That is the result of advanced forecasting is the prediction of the emergence of new failures in the means of communication, that is determined with a probability of time during which there will remain a health communication after repair. While the technical implementation of the forecasting process known as technical devices from a wide range of technical literature (the new diagnostic tools: Directory / WLI, Pre, Wearly, etc.. Under the General Ed. VLA. - M.: Mashinostroenie, 1989, 672 S., PP 156-161; workbook forecasting / Ivestream-Lada. - M.: Thought, 1982. - 430 S., str-293).

The degree of importance (priority) is determined by the results of the forecasting and analysis of time values within which there will remain a health communication. The more time it takes, the higher the priority repaired means of communication.

To perform aggregation repair is a well known effect in which defective items communications (aggregates) are replaced or renovated in advance (GOST 18322-78. The system of technical maintenance and equipment repair. Terms and definition is possible. Item 45, page 7).

Evaluation of the effectiveness of the method described in the application can be done using a comparative evaluation values of the load factors (employment) (KC) and downtime (Kp) repairmen. The procedure for the calculation of load factors (employment) and idle is described in (Novikov O.A., Petukhov, S. Applied theory of mass service. M., Soviet radio, 1969. - 400 C.).

Load factor (employment) is determined by the formula:

where NC- the number of employed repairers;

n is the total number of repairmen.

Downtime rate is determined by the formula:

where N0- number of free maintenance.

To determine the load factor of repair only repair bodywhen carrying out repairs of all types of communication means (m) for time t, it is necessary to use the formula described in (Novikov O.A., Petukhov, S. Applied theory of mass service. M., Soviet radio, 1969. - 400 C.):

where- load factor RHO j-th type for repairs of similar means of communication;

nj- the total number of repairmen j-th type for repairs of similar means of communication;

m is the number of types is redst connection.

Evaluation of the effectiveness of the proposed method of construction of mobile RO communications will consider ways of communication in the emergency area (regional center). Option communication in the emergency area described in (Bulgak V.B. have been, Varakin LE, Krupnov AU and other basic management communications of the Russian Federation / Under the editorship Varakin LE, Krupnova AU - M.: Radio and communication, 1998, RES, p.93).

Analysis of the number and types of applied communications in the regional center demonstrates that for repairs seven different types of communications with the existing way the organization needs at least five different types of ATU. Moreover, for each of communication tools such as satellite station, radio station, radio relay station requires its own specialized ATO.

For example, the regional center requires the following ATO:

ATO intended for radio repairs;

ATO intended for repair of radio relay stations;

ATO intended for repair of satellite communication stations;

ATO, designed for field repair of the cable;

ATO intended for repair of power supply devices.

If each ate five masters repairmen total number of repairmen - n=25 (people).

For example, the satellite communication station (CS) has failed. To restore this station tre is : ATO, designed for repair of satellite communication stations (with the number of repairmen 5 (people)).

Thus, the load factor of the repair of the authority of the regional center is (for five ATO):

Assume that a mobile communications regional center will service and repair the body, formed on offer in the invention method. First, the RM will be designed for the repair of receivers, the second is for repair of transmitters, and the third for repair of power supply devices, and the fourth for repair field cable. Each RM two repairman.

For repair of satellite communication station (CS) will have two repairman at each RM, then the load factor of the repair body is equal to:

The effectiveness of the proposed method is equal to:

Thus, the effectiveness of the proposed method is equal to 20%.

The way to build a mobile repair body communication, which consists in the control of the instrument, in this case before the control node of electronic equipment (REE) is connected to an automated system for monitoring and diagnosis, is retrieved from the database control program, including benchmarks, is issuing a test signal is, this sets the tone settings of the special form (to control analog and analog-to-digital circuits and high-frequency signals (for control nodes REA containing high-frequency part), the control procedure is performed in stages (steps), and the synchronization of sources of supply test signals and measuring the response signals is provided by applying a clock signal of a given frequency from the programmable synchronization unit, and the control sequence of the issuance of the test signals provided by the measurement of the response signals and comparing them with the reference, is on the program under control of the control computer complex, collectively supplied to the node REA control reference test signal receive a set of measured parameters of the response signals, which are compared to reference values of the response signals, when the measured signals are within tolerance nodes REA be considered fit, when the parameters of the measured signals for the tolerance zone is given fault message this node REA and the need for diagnosis of faults; diagnose faults from the database is retrieved, the program diagnosis, including a set of sequentially-issued diagnostic tests, about the ESA diagnosis is performed in stages, at the first stage on the site are served diagnostic tests, allowing you to pre-locate faults in the schema node, after the preliminary localization of the point of refusal is to drill the point of refusal, to this end according to the program of diagnostics issued instructions for the connection of measuring devices at corresponding intermediate points in the circuit, based on the analysis of parameters of signals received using measuring instruments identified problems or issued clarification on a similar analysis of other portions of the electric circuit node, the measurement process signals in the intermediate points of the site and the subsequent comparison with the corresponding parameters of the reference signals for the same points continues until a complete diagnosis of the entire circuit node, the sequence view of the intermediate circuit node is set based on the characteristics of the build site, and also taking into account the principle of operation of the node, based on the results of the diagnostic repair node REA (elimination of detected errors), then re-inspected the repaired node REA as indicated above, if the control is successful, the node REA admits fit (refurbished)if you set the deviation from the reference characteristics, h is about means of an unresolved fault, node REA re-runs diagnostics to identify unresolved fault, the repair process and control ends when the node CEA is recognized as valid, differing diagnose and aggregate repair at the same time as several homogeneous and heterogeneous mobile communications in the field, based not on the type of these means of communication (radio, radio-relay, tropospheric, space, wired), and the type of equipment repair communication equipment (receivers, transmitters, power supply and antenna-feeder devices, and others belonging to different media types), identification (definition) type communication means connected to the repair body is chosen program of diagnosis, depending on the type of the connected communication tools, diagnostics equipment, means of communication, is determined by the degree of importance (priority) of the repaired equipment repaired in the means of communication, is the aggregate repair.

FIELD: technical diagnostics.

SUBSTANCE: method includes, for each set of input test signals, forming of prior matching response signals for intermediate points of controlled device. Received response signals at outputs of product are compared to parameters of standard response signals and level of their match is determined, in case of mismatches broken branch of functional circuit is determined and diagnostics is repeated by substituting all formed combinations of input signals, after that diagnostics of erratic portions is started.

EFFECT: simplified method.
