The invention relates to automation and computer technology, in particular, to technical means used to train operators in the fault localization skills in electronic equipment, and is an improvement of the device according to the author. St. No. 1439654.

The purpose of the invention is to expand the didactic capabilities of the device.

The drawing shows the block diagram of the device

The device for training the operators includes an operator console 1, a malfunctioning unit 2, comparators 3, AND elements 4. OR elements 5, delay element 6, time counter 7, signaling node 8, response input node 9, switching element 10

Operator pools 1 contains register 11, switch 12, memory block 13, counter 1 4 errors.

The malfunctioning unit 2 comprises a decoder 15, separation elements 16, the response input unit 9 contains elements of the first group 17, elements of the second group 18, the first element OR 19, the first element 20 of differentiation, the second element OR 21, the second element 22 of differentiation, the third element OR 23. pulse transformer 24, rectifier 25, comparator 26, limiter amplifier 27. isolating element 28

The operation of the proposed device in the fault simulation mode of increased degree of complexity, which corresponds to the closure of the first input with the output of the operating mode switch, is no different from the operating logic of the known device, with the exception that the operator’s pulse pulse comes from the output of the limit amplifier 27 to the input of the error counter not directly, but through the element OR 23

This mode is most appropriate to apply after operators have mastered the troubleshooting skills by searching for and replacing suspected plug-in units.

The operation of the device in the second mode - (imitation of malfunctions of the hardware units) consists of the following. The instructor translates the mode switch to the second position, providing connection of the switch output to the third output of the answer-input node. Next, the malfunction address code is entered in register 11. This code, after receiving the recording signal from switch 12, is recorded in memory block 13 and fed to the input of the decoder 15, the corresponding output of which produces a voltage level equal to the nominal amplitude of the signals circuits interfaced with a radio electronic device

Ratura. The indicated voltage level goes directly to the corresponding control output of the malfunctioning unit 2 and through the isolating

element on one of the information outputs of the same block, covertly connected to one of the contacts of one of the connectors of the interconnects of the serviced equipment. After the occurrence of this voltage error level in the operation of the serviced equipment, failures are observed, recorded by means of hardware and software monitoring and diagnostics.

Simultaneously, the signal from the output of switch 12 is supplied directly

to the installation input of the counter 7 time, as well as through the delay element to the input of the launch of the same counter. The latter starts counting the time from the moment of entering the fault into the serviced equipment. In this case, the process of troubleshooting consists in localizing and trially replacing the hardware unit suspected of a malfunction with a known-good spare unit.

In this case, each attempt to replace the unit

5 equipment leads to the addition of units in the counter 14 errors. This is achieved by the fact that from all the hardware units through the corresponding information inputs of the device to the first and second inputs of the elements And 17 when the working position of the blocks through the corresponding normally closed contacts of the block connectors receive voltage levels that set the level of logical zero at the outputs of the corresponding elements And 17 In the case of removal from the equipment of any of

5 blocks for its replacement, at the output of the corresponding element AND 17 there is a level of a logical unit that goes through the element OR 21, the differentiation unit 22 and the element OR 23 to the input of the counter of 14 errors, increasing its content by one. When a new unit is installed on a workplace, the status of the error counter does not change. If a block is removed from the apparatus, the input of which is affected by the interfering potential from the information output of the device, then, in addition to the incremental pulse of the error counter, a fault output signal is generated, time counter 7 records the time spent on troubleshooting, and counter 8 - the number of errors

0 and, as a result of the memory unit being reset, the interfering potential is removed, which prevents the normal functioning of the equipment. When installing the plug-in unit at its workplace, the equipment functions normally.

The assessment of the operator's level of skill is determined by the outcome of the average time spent on the localization of the malfunction5

the average number of errors made during a specific training cycle.
