Measured by the terminal 7, the values of the parameters of the technical condition of the controlled part of the accepted technical system 8 are compared with permissible. The discrepancy between measured values with valid is a sign of approaching equipment to the limit state or a sign of failure. By successive measurements at appropriate points on the basis of the indications of repair documentation identify faulty replaceable integral part of the lower level of disaggregation accepted technical system (referred to in the technical literature also replaceable structural elements). Seize suspected denial of interchangeable structural elements of the design served the technical system 8, and in their place establish a working replacement items of the same type from a single SPTA kit included in the kit supplies the accepted technical system 8. Repeated measurements with the help of a remote terminal 7 determines the restoration of accepted technical system 8. All intermediate and end the global results of operations for the control of technical condition and repair of the accepted technical system 8 through the terminal 7 in the dialog mode is introduced into the Central computer 1, including data on faulty replaceable structural elements removed from the accepted technical system 8 in the process of repair.
Faulty constructive replaceable elements are transmitted from the accepted technical system 8 in the process compartment RDK 5 for repair. If necessary prior disassembly of the complex units or necessary to carry out preparatory work (repair, drain mud and the like), the data is replaceable component parts can pre-enrol on the advanced organized external technological jobs 11.
Received in the process compartment RDK 5 interchangeable component parts serviced technical system to be repaired, come in technological jobs 4 and move from one process area to another in the sequence of technological process of repair. The procedure of control of technological process of repair with the use of the claimed system (see drawing) can be seen on the example of repair of replacement of structural elements of electronic equipment (REE).
Each of the received repair replacement item REA previously be registered in the Central computer 1 system. You enter the type replaceable element and its identification number (serial number and affiliation to the design of the EAC is urivaeva technical system 8). Registration type and registration data, in case of duplication in the form of bar codes, which are entered into the Central computer 1 by using the barcode reader included in the scope of the Central computer 1.
Registered faulty replaceable element (object repair) comes (in the direction of a technical process and in accordance with the instructions of the repair documentation, located in the computer database 1) for the next technological workplace 4-1. The amount of TRM 4 and combined with them arm 2 control the process operations defined by the specialization RDK 5 and implemented as part of SDC 5 technological process of repair. In case of repairs or replacement of items of electronic equipment first TRM 4-1 is a technological workplace monitoring and Troubleshooting replaceable parts. Combined with TPM 4-1 workstation 2-1 represents the appropriate automated system monitoring and diagnostics (ASAC), intended for performance monitoring and fault diagnosis of functional units of electronic equipment.
Before performing the instructions on TRM 4-1 from the Central computer 1 system via the interface line 3 arm 2-1 (ASAC) is transmitted and repair documentation for replaceable items Remo is one including diagnostic tests, as well as an indication to the operator of ASAC for each sequence of actions when monitoring and diagnosing each replaceable item. For instructions, reproduced on the screen of the workstation 2-1, operator TRM 4-1 mounts the removable element (object repair) to ASAC and performs iterative control process. Upon confirmation of the failure of the inspection object on the screen AWP 2-1 will be prompted to conduct iterative procedure fault diagnosis. In process fault diagnosis on the screen AWP 2-1 issued instructions to the operator for connection of control probes according to the diagnostic algorithm (with on-screen display of the workstation 2-1 design image controlled replaceable unit and relevant tips on the connection points of the probes). The results are determined defective radio electronic elements (REE) in the controlled replacement of an item of repair), the types and reference designators defective REE to be replaced. The results of the monitoring and diagnosis (identification of the type and number of the test object) is transmitted from the workstation 2-1 via the interface line 3 to the Central computer 1.
Next faulty replaceable element in accordance with the sequence of the process, reflected in the repair documentation in SOS the Ave Central computer 1, is transmitted from a technological point of control and diagnostics TPM 4-1 on technological workplace electrogravimetry works TRM 4-2. To manage the transition process on the workstation 2-1 and workstation 2-2 reproduced instructions on which operators TRM 4-1 and TRM 4-2 entered the relevant confirmation (on the transfer of facility repairs and on acceptance into operation of the object of repair).
Upon receipt of the object of repair on TRM 4-2 from the Central computer 1 in accordance with information contained in the databases of the computer 1 technological repair documentation and received from AWP 2-1 results of the fault diagnosis on the workstation screen 2-2 are given consistent information:
- on preparation of technological tools;
- about the required REE and consumables;
- about the sequence of actions to remove the faulty REE and installing in their place intact REE composition of the corresponding stacking repair spare parts (included in the delivery of technological equipment TRM 4-2).
Preparation of technological tools (e.g., soldering installation with the appropriate nozzles) and its application (for example, faulty feeding REE and installation and soldering healthy REE) is made according to instructions received from the Central computer 1 on the workstation screen 2-2. Thus to identify the repair shop and on the screen the workstation 2-2 reproduced image is a necessary part of construction repair - emitting image remanufactured REE (e.g., color or flashing a portion of the image). Performing a given procedure is confirmed by means of the manipulator, the supplied arm.
To accelerate search of necessary REE and technological tools are used to specify the coordinate position of the staff of finding the appropriate styling ZIP repair or technological equipment on the shelves in the composition of the TRM. Identification of the stacking and packaging the composition was found laying ZIP repair is carried out by reading an identification bar codes on buildings styling and packaging REE, materials and tools. The bar code reading is carried out using barcode readers, the included arm 2. Identification of the recognition result of the barcode is displayed on the screen of the workstation 2. All information about the operations of replacement of REE and other mounting elements fixed in the process of repair of replacement item TRM 4-2, is passed from the workstation 2-2 in the Central computer 1. On the basis of comparison of the executed works and the earlier results of fault diagnosis, the Central computer 1 controls the completeness of the performed operations for repair (replacement REE), and performs the metering REE, materials and wear of technological tools (including possible is olaki tool).
Refurbished replacement element according to instructions from the Central computer 1 is supplied with TRM 4-2 on TRM 4-1 to control the recovery and Troubleshooting. In case of additional fault persists replacement item is being returned to TRM 4-2 for Troubleshooting. Additional work on TPM 4-2 on elimination of detected errors is performed under the control of the Central computer 1 system using AWS 2-2 similarly to the above procedure. After a full Troubleshooting electrical circuits replaceable unit (replacement of all defective REE and damaged conductors) facility repairs is transmitted to the TPM 4-3 to eliminate the existing damage of structural elements replaceable element.
Work to repair the damages designs are produced under the control of the computer 1 using 2-3 WKS. Interactive search of technological tools, parts and materials for repair design replaceable element using AWS 2-3 is similar to that previously reviewed the procedure for replacing defective REE on TRM 4-2.
After repairing the damages designs replaceable element (object repair) with TPM 4-3 returns on TRM 4-1 to control workability, because in the process of SL is Sarno-mechanical operations on the TPM 4-3 may be compromised the integrity of electrical circuits or damaged REE. In case of Troubleshooting facility repairs is transmitted to the TPM 4-2 for Troubleshooting. Good facility repairs is transmitted to the TPM 4-4 for recovery (broken in previous stages of the process) moisture-proof coating and marking.
The procedure for the preparation of technological tools and materials to restore the moisture-proof coating and markings on TRM 4-4 under computer control 1 system is based on the technology of repair documentation similar to that described procedures that are performed on TRM 4-2 and TRM 4-3.
After restoring moisture protection and marking refurbished replacement element is passed under computer control 1 system with TPM 4-4 on TRM 4-1. Here is the final performance monitoring refurbished replacement item. In case of failure of a replaceable unit is fault diagnosis. When detecting faulty electrical circuits, or REE facility repairs transmitted TRM 4-1 on TRM 4-2, and then repeats the private loop elimination of additionally detected faults and subsequent recovery in a waterproof coating.
Upon confirmation AWP 2-1 in the composition of the TRM 4-1 full health, refurbished replacement item is recorded in the database of the computer 1 with the system as restored (completely renovated) and transferred (printed on the printer that comes with the computer 1 of the accompanying document) in a single ZIP serviced technical system 8.
When revealing the results of monitoring and diagnostics (at the beginning of the technological process of repair is submitted to the SDC replaceable unit) final marriage, is not subject to repair the removable element is in the database of the Central computer 1 system, placed in a separate technological containers as part of SDC and later passed to disposal. In the computer 1 are formed the source data for subsequent replenishment single ZIP repaired product in connection with the seizure of this replacement item is beyond repair.
Thus, due to the introduction of additional structural elements and relationships between elements in accordance with the drawing to achieve the stated technical effect, namely:
- implemented interactive control of technological operations of repairing machines and technical systems 8 and revealing in the process of repair, defective replacement parts (replacement of structural elements) accepted technical system. Management repairing machines and technical systems 8 and its interchangeable parts in the composition of the RKD 5 is covered by a single technological process on the basis of repair documentation uploaded into the database of the Central computer 1 system in full accordance with Directi the Noi technology;
