An example of a known implementation of this method, taken as the closest analogue is the way to patent RU 2265236 (G05B 23/02, publ. 27.11.2005, bull. No. 33).

The main disadvantage of the known technical solutions for patent RU 2265236 is the lack of reliability of control because of unreliable contact of the object of control, and also because of errors in the use of transitional devices when connecting the test object.

The purpose of the claimed technical solution is:

1) excluding the impact of human factor on the reliability of connection of the object of control;

2) improving the reliability of health monitoring and fault diagnosis REA due to the introduction of quality control connection of objects of control to the TV input test signals to the channels of the datalogger parameters of the response signals;

3) improving the performance of health monitoring and fault diagnosis REA;

4) reduction requirement is for staff development.

This technical effect is achieved in that the test object is connected to the outputs programmable input test signals and the inputs of the measuring parameters of the response signals, using a removable adapter. Removable adapter set the type ID of the adapter. Before the beginning of the control inputs identifier serves to respective outputs programmable input test signals, the combination of the polling signals, measured with additional channels of the datalogger parameters of the response signals of the identification signals and form on the basis of the identification code, which is passed from outputs of the respective channels of the datalogger parameters of the response signals in the computer, comparing in the computer the received identification code with a type code of interchangeable adapter to be used in the control of this type of object control, develop into a computer message on the reliability of the type and reliability of connection used interchangeable adapter and the readiness of the system for connecting the test object and for process control health and Troubleshooting REA. In the object control have been added to the object ID of the control. To control the type of object control and reliability of its connection to removable adapter p is ed the beginning of the control serves to input the ID of the control object, from the corresponding programmable input test signals, the combination of the polling signals, measured with additional channels of the datalogger parameters of the response signals of the identification signals and form on the basis of the identification code of the test object, which is passed from outputs of the respective channels of the datalogger parameters of the response signals in the computer identified by the computer connected to the test object. According to the identification results in the computer produces the message type of the connected object of control and the reliability of the connection of the control object to the replacement adapter.

Block diagram of a system for automated performance monitoring and fault diagnosis of electronic equipment, implements the claimed method shown in the drawing.

The system of automated performance monitoring and fault diagnosis REA (see drawing) includes the inspection object 1 (for example, in the form of a functional node REA on the PCB), which via a plug-in adapter 2 is connected to a software-managed sources 3 input test signals (including software-controlled power supplies) and to the inputs of the meter 4 parameters of the response signals. Inputs programmable sources 3 test input signals and the outputs of the probes 4 p the parameters of the response signals is connected to the relevant control outputs and inputs of the computer 5. Removable adapter 2 is the ID of the adapter 6, the inputs of which are connected to the outputs of the additional channels programmable sources 3 input test signals, and the outputs of which are connected to the inputs of additional channels of measure 4 parameters of the response signals. In the inspection object 1 added object identifier control 7, the inputs of which through chain replacement adapter 2 is connected to the auxiliary outputs programmable sources 3 test input signals, and outputs, which through the appropriate chain of interchangeable adapter 2 is connected to the inputs of additional channels of measure 4 parameters of the response signals.

In computer memory 5 pre-recorded values of the identification codes of adaptors 2 (across the range of the used adapters), as well as the identity of all types of control objects 1. In software modules identify the connection between the identification codes of the types of adaptors 2 and identification codes of objects of control 1, for connection which are appropriate adaptors 2.

Before beginning the procedure for health monitoring and fault diagnosis of the type of test object 1 is introduced into the computer 5. For a given type of test object 1 from the database computer 5 WPI is ekaette logically interconnected identification code of the removable adapter 2 and the identification code of a given type of test object 1. Interchangeable adapter installed and connected to the source 3 input test signals and measure 4 parameters of the response signals. The replacement adapter 2 installing and connecting the test object 1. To verify the reliability of connection removable adapter 2 to 3 sources of input test signals and measure 4 parameters of the response signals to the inputs of an identifier of the adapter 6 is available from the respective outputs of programmable sources 3 input test signals, the combination of the polling signals, measured with additional channels of the datalogger settings 4 the response signals, identification signals, and form on the basis of the identification code. Generated identification code is passed from the outputs of the respective channels of the datalogger settings 4 the response signals in the computer 5, the received identification code is compared in the computer 5 with a type code of interchangeable adapter 2 to be used during the inspection this type of inspection object 1. By comparing the results in the computer 5 generates a message on the reliability of the type and reliability of connection used interchangeable adapter 2 and the readiness of the system for connecting the control object 1, and for the process of health monitoring and fault diagnosis.

To control the type of test object 1 and its reliability under the your to removable adapter 2 (in the presence of the test object 1 object identifier control 7), to the inputs of an identifier of the inspection object 7 served with respective outputs programmable sources 3 input test signals, the combination of the polling signals, measured with additional channels of the datalogger settings 4 the response signals, identification signals, and form on the basis of the identification code of the test object 1. Generated identification code is passed from the outputs of the respective channels of the datalogger settings 4 the response signals in the computer 5. Received identification code is compared in the computer 5 with the ID of the control object to be controlled. By comparing the results in the computer 5 generates a message about the type of the connected control object 1 and the reliability of the connection of the test object 1 to removable adapter 2.

If the results are positive identification of interchangeable adapter 2 and the test object 1, the system is ready for inspection and ensures the reliability of the control object. An automated procedure for identifying the type and quality of connection removable adapter 2, and identify the type and quality of the connection of the test object 1 eliminates time wasted on repetition control and diagnostics of the control object 1 due to improper use of adaptors 2 and due to bad connections.

In computer memory 5 is fixed combination of input test signals, which can be traced back to failures. After completion of the test the test object 1 for all combinations of input test signals and recording of all detected malfunctions automated performance monitoring and fault diagnosis is switched to the mode fault diagnosis REA.

Fault diagnosis is carried out by connecting the control rods with the system to set on instructions from the computer 5 to the intermediate points of the electrical circuits of the control object 1. The diagnostic procedure is performed in accordance with pre-formed and stored in the memory of the computer 5 system diagnostic tests. After connecting the probe system to the specified intermediate points of the computer 5 executes the program of the control problem in this section of the circuit. Commands from the computer to the inputs of the control object are re-specified combination of input test signals, for which the failure was detected this electrical circuit when performing reviewed the control procedures REA. Produce measurement values of the response signals from the monitored circuit and comparing them with reference values of these parameters are located in computer memory 5 as part of the diagnostic tests for this type of product CEA.

In the sequential traversal of the intermediate points of each identified process control faulty electrical circuit of this control object 1 locate the faulty parts of these circuits are located in these areas faulty radio electronic elements or damaged wires.

The computer 5 is equipped with software that implements the algorithm are braimah for health monitoring and fault diagnosis of the control object 1, includes software modules identification of adaptors 2 and test objects 1. Diagnostic tests are formed by one of the known methods (for example, patent RU 2261471)
