The drawing shows a block diagram of the device. The device contains a block 1 of control and synchronization, a switch 2-A, a block 5 of stimulus generators, a block of 6 equivalent loads, blocks 7-9 of comparison, {supervised object 10, memory P of contact numbers, memory 12 erroneous tests, memory 13 erroneous parameters, block 14 for normalization of parameters, block 15 of indication, memory of 16 actions and reactions, counter 17, register 18 for setting parameters, block 19 of reference signals, block 20 of delays, comparator 21, element OR 22. The device works as follows. Information can be entered into the device from punched tapes or magnetic tape, the information on which is located for each test set by zones in the following sequence: test set number, zone for determining the input effects of the diagnosed object 10, zone for determining reference values of reference levels and masks for controlled outputs, zone setting the time delay, the zone determining the expected output reactions of the object being diagnosed, the zone determining the parameters of special telephone signals area determining numbers diagnosed output contacts and internal analog parameters reference values for them. To implement a general device control in front of the rows, test cases are placed in the service line of the beginning of the test tables, and after the last test set - the service line of the end of the test tables. Block 1 decrypts the service characters of the entered information and generates commands to enter information into the corresponding units of the device. Using the input information stored in memory 16, the corresponding signals are generated, which in the switch 3 generate analog influence signals and in block 6 the necessary load equivalents are set , connect them to the required contacts of the diagnosed object 10, and also switch the telephone signals of a sinusoidal and special form produced by the unit 5. The next area of the entered information sets up block 19 to output the required values of the reference levels to the comparator 21, and block 7 to comply with the mask of controlled outputs. Next, block 1 starts block 20, which, after the set delay time required due to the low speed of the diagnosed objects of hybrid TECs of quasi-electronic PBXs, generates a signal of block 9. The latter compares the 21 output of the object being diagnosed converted by the comparator with the expected output reactions stored in memory 16. In the event of a mismatch, block 9 generates a mismatch signal via element OR 22 to block 1, which generates a control signal to block 7 to check the result look at the mask. If the mismatching contact is not masked, an error signal is generated, according to which unit 1 issues a command to put 11 numbers of missed contacts into memory, and 12 numbers of erroneous test sets to memory. After the analysis of the output reactions is completed, if there is an information zone about the expected parameters of special telephone signals from the memory signals 16, the switch k is activated and connects the corresponding contact to the input of the tA block. The latter performs the preliminary transformation, division or multiplication of the measured signal with the subsequent conversion to a discrete form. This result is compared by block 8 with the reference parameter values coming from register 18, and if the result goes out of the limit values, a mismatch signal is generated, which through the OR 22 element goes to block 1. The latter ensures that error number 12 is entered in memory 12

OUTPUT parameters of special telephone signals of hybrid TECs of quasi-electronic PBXs, as well as diagnostics of malfunctions in these TECs by automatic analysis of signals at the internal contacts of the unit. It allows the use of diagnostic dictionaries when searching for and locating faults in a TEC.

Claims (1)

The use of the proposed device makes it possible to reduce the nomenclature of the diagnostic set five times, and in memory 13, the measured and boundary reference values of erroneous parameters. After completion of the monitoring procedure for all the entered test sets, block 15 provides an indication of the numbers of the test sets that caused the mismatch and the numbers of the output contacts on which the mismatch occurred or the value of the analog parameter does not match. Next, a failed node is determined using the diagnostic dictionary. the object under diagnosis 10 and the internal contact numbers and the corresponding reference values of the analog parameters are entered on them. After that, input actions are applied to the diagnosed object 10 and in the above-described sequence, the signals are measured and analyzed at the internal contacts and the fault in the object is localized. | Unit 1 provides the installation operation both in automatic mode and in auxiliary modes: multiple cyclic, with non-matching stop, step-by-step and address mode. Auxiliary modes are used during adjustment and repair of the tested blocks. In addition, the device provides an automatic self-monitoring mode, in which the input actions are sent to the block I by the switch I.
