At the same time, the block of autonomous control and measuring devices contains a set of autonomous generating and measuring devices installed in separate buildings and equipped with their own power sources. The test control block is based on the elements “AND, OR, NOT, RS-trigger, IK-trigger, D-trigger” and other elements of the old-generation computer technology (156 and 165 series), discontinued. The electronic switch is made on electromechanical relay elements. The control computer is designed as a special computer with a hard-wired control program.

A disadvantage of the known system for monitoring and diagnosing electronic devices is insufficient productivity,

associated with a large investment of time for the connection and preparation of instrumentation for the diagnosis of control objects.

The objective of the utility model is to increase the performance of the monitoring and diagnostic system of electronic devices.

The technical result that provides a solution to this problem is to increase the degree of automation of control and diagnostics of typical elements of the replacement of RES.

The solution of this problem and the achievement of the claimed technical result is ensured by the fact that an automated system for monitoring and diagnostics of radio-electronic devices, containing a control computer with an indicator device, a unit of autonomous control and measuring devices with a control unit for devices, connected through a device for connecting control objects and a low-frequency switch with a test device control, and the unit of autonomous instrumentation includes a high-voltage voltmeter, ge a high-pulse impulse generator, a precision generator and a source of precision voltages, and a device control unit, a test control device, and a low-frequency switch are digitally controlled and connected by control and information signals to a control computer; according to a utility model, it additionally contains a controller and a block of digital control and measurement modules installed on a VXI bi-directional active interface bus connected to a computer, low-frequency switch, test control device and a low-frequency switch, moreover, the block of digital control and measuring modules comprises a digitally controlled low-frequency pulse generator, a frequency meter, a digital voltmeter, a synthesizer, a digital oscilloscope, a vector meter, and a spectrum analyzer.

At the same time, the device for connecting control objects contains serially connected connecting device and a removable adapter, as well as high-frequency and low-frequency connectors for

connecting the control object for high-frequency and low-frequency signals. The test control device comprises a controller, a test generator, and a signature analyzer mounted on a bi-directional active interface bus with 192 digital channels.

The introduction of a controller and a block of digital control and measurement modules installed on a VXI bi-directional active interface bus connected to a computer, a low-frequency switch, eliminates the need for mechanical connection of measuring devices to the monitoring and diagnostics circuit of monitoring objects, and thereby increase the system performance. In addition, the use of a high-speed VXI bus allows increasing the speed of signal information exchange in the system and, thereby, further improving system performance. The implementation of instrumentation in the form of digital modules eliminates the need for separate bulky cases, autonomous power sources. The consequence of this is an additional decrease in the overall dimensions of the system. The supply of the device for connecting control objects with a removable adapter, as well as with high-frequency and low-frequency connectors allows to further increase the system performance due to the quick adaptation of the connecting device when replacing the type of a typical replaceable element (TSE) of a distribution zone. Providing test control with a controller, a test generator, and a signature analyzer installed on a bi-directional active interface bus with 192 digital channels allows testing digital products of RES practically of all existing types and, thereby, further improving the system's functionality.

The utility model is illustrated in the drawing, where Fig. 1 shows a functional diagram of an automated system for monitoring and diagnosing electronic devices; figure 2 is an example of a display

on the computer screen of the device connection diagram for checking the control object - high-frequency cell FK262-03.

The automated system for monitoring and diagnostics of electronic devices contains a control computer 1 with an indicator device 2 (display), a unit 3 of autonomous control and measuring devices, a unit 4 for controlling devices, a device 5 for connecting control objects 6, a low-frequency switch 7 with a test control device 8, block 9 digital control and measurement modules 10 with a controller 11. Block 3 of autonomous control and measuring devices, includes a high-voltage voltmeter 3.1, a powerful pulse generator 3.2, a precision gene Herator 3.3 and source 3.4 of precision voltages. Unit 4 control devices made in the form of an electronic switch connected to the control inputs to the computer 1, and the outputs to devices 3.1-3.4 unit 3. Devices 3.1-3.4 are equipped with connecting cables for connecting to the device 5 for connecting the objects 6 control. The device 5 for connecting the objects 6 of the control contains serially connected low-frequency connector 5.1, a connecting device 5.2 and a removable adapter 5.3. The high-frequency inputs of the adapter 5.3 are connected through a high-frequency connector 5.4 to devices 3.1-3.3. block 3 and the device 8 test control. The test control device 8 contains a controller with RAM and ROM, a test generator and a signature analyzer installed on a bi-directional active interface bus with 192 digital channels (not shown in Fig.) Connected via an electronic low-frequency switch 7 with a low-frequency connector 5.1 of device 5. Digital inputs the outputs 12 and 13 of the device 5 and the switch 7 are respectively connected to the computer 1 with a bi-directional active interface bus 14, on which the controller 11 and the block 10 of the control and measuring modules are installed. Block 10 comprises a digitally controlled low-frequency pulse generator 10.1, a frequency counter 10.2, a digital voltmeter 10.3,

synthesizer 10.4, digital oscilloscope 10.5, vector meter 10.6 and spectrum analyzer 10.7.

Automated control and diagnostic system works as follows. A removable adapter 5.3 is installed on the connecting device 5.2. Next, in the connector of the adapter 5.3 install the object of control - a typical replaceable element (TSE). Simultaneously turn on the computer 1. On the on-screen menu of the display 2, the computer 1 indicate the type of control object 6 installed on the adapter 5.3. At the same time, data characterizing the control and measuring circuit and connection parameters are selected from the computer memory 1. The display 2 of the computer 1 automatically displays the required measuring connection diagram, types of connecting wires and adapters for the selected TSE (figure 2). The operator monitors the connection diagram on the display 2 of the computer 1 and connects the devices 3.1-3.4 with the connecting device 5. Then, using the keyboard and a manual manipulator of the computer mouse type 1, the operator controls the bi-directional interface bus 14, the control unit 4 and the switch 7 for electronic connection elements 10.1-10.7 and devices 3.1-3.4 into the circuit observed on display 2 of computer 1. In this case, block 3 of digital-controlled measuring devices 3.1-3.3 and source 3.4 of precision voltages, as well as measuring modules 10.1-10.7 of block 10 are combined through a router p (switching channel bus 14 and the switch device 7 and channels 8) in the measuring chain on a time division transmission and reception channels. Further, according to a given program, the computer 1 generates digital signals sequentially in time containing the parameters of the input actions required for monitoring the TSE (for example, the duration and amplitude of the input pulse). These signals are transmitted via the interface bus 14 to the digital-controlled generator 10.2 of block 10. The generator 10.2 converts the input digital signal into analog form and, through the corresponding channel of the bus 14, the switch 7 and the connecting device 5 outputs it to

the current input of the verified object 6 TSE. The response signal of the TSE to the input action from the corresponding (input signal) output through the connecting device 5 is returned via the currently available channel of the switch 7 and bus 14 to the corresponding measuring input of block 10, for example, to the spectrum analyzer 10.7. The analyzer 10.7 determines the parameters of the response signals. When using analog measuring instruments 3.1-3.3, the measured parameters are converted to digital form and, through block 4, are supplied to computer 1 for processing. The TSE computer 1 compares the measured parameters of the response signals with reference values. In the case of deviation of the values of the response parameters of the TSE from the permissible values of the computer 1 stops the monitoring process and begins the diagnostic process (search for a faulty element in the TSE). When diagnosing faulty elements, the parameters of the TSE response signals are displayed on the computer screen 1. For the analysis of faults, diagnostic cards and computer memory data 1 are used automatically and in the dialogue mode of operation. In this case, faults are detected up to an integral element of the TSE. When monitoring digital TSEs, an additional test control unit 8 with 192 bi-directional digital channels and a signature analyzer, structurally located in device 8, are additionally used. The test control device 8 generates 4 Kbps RAM tests per channel. The frequency of information exchange with the TSE control object is programmed in each test set within 0.0001 Hz - 2.5 MHz. There is a looping of any part of the test, both a given and an infinite number of times with the issuance of a clock pulse for any given set. Troubleshooting using a signature analyzer is performed in a dialogue mode with the indication on the display of 2 computers 1 points being monitored and their locations on the field of the object under control. Fault localization is provided up to the component of TSE. In the case of the presence in the object 6 of the control of ring structures characteristic of TSE with

ROM, fault localization in them is provided to a group of replaceable elements. In this situation, to determine the faulty replaceable element in the group, an in-circuit control tester (not shown in Fig.) Is used under the control of computer 1. In a similar way, high-frequency TSEs are checked. The difference lies in the selection of the appropriate source of control signals and the measuring device of block 10 and connecting them via the interface bus 14 and switch 7 to the measuring circuit for monitoring the TSE using computer 1.

To check the next TSE, the corresponding adapter 5.3 is installed on the connecting device 5, the monitoring object 6 is connected to it and the monitoring process is repeated.

The utility model is designed at the prototype level.
