The device for monitoring the installation works as follows.

Checking the product by applying voltage

0 level sequentially to all terminals I.I ... 1./g of group I of contact elements, excluding those for which communication is established by the valid test steps. The use of block 3 transistor switches 3.1 ... 3. / in the generator 2 of the output sequence allows you to remove restrictions on the number of branches in the U) product under test 14. Switch 7 is made a single day of inputs and outputs of the device. Upon issuing

to the control bus of switch 7 through the interface 9 of the information processing unit 8 of the number b and the recording signal, information bits are recorded through register 4 and block 3 of transistor keys to the terminals of group I of contact elements (& - / ylx L -. When applying to the control bus of the switch 7 numbers & and read signal, if there is a reading of / bits of information from the terminals)) L - And through block 5 of level converters and a buffer of 6 inputs (L is the number of bits of the data bus in interface 9 between switch 7 and information processing unit 8. According to the algorithm functioned device, the information processing unit 8 in portions of / 6 digits records an i-bit binary number with

0 hotels are found, which through connections in object 14 cross-connects to other contact groups of I contact elements. Then, reading the portions of bits / g-bit binary from pennies of I contact elements through block 5 of level converters, input buffer 6 and switch 7 to information processing unit 8 takes place. The read / 2-bit number contains 0 in the bit corresponding to the terminal being tested and in the bits corresponding to the terminals connected to the tested one through the test object 14. This number in block 8 of the processing of the comparison is compared with the sample stored in the storage device II of long-term memory, and if there is a mismatch, a conclusion is made about the presence of a defect. Further bitwise joint analysis of the sample and the read information allows you to determine the terminal number and the type of fault: K standard bit — I, K information bit O — closure of the tested Lie terminal with K-to; To the standard bit O, To the information bit: I - breakage of communication being tested. th terminal and K-th. This information is displayed on the terminal 13 and the printing device 12. In addition, the read information is accumulated in the / 2 - bit binary number ME HO. In this number, a bit is assigned to kadma kyemme, which is set to I if the terminal is checked or has a connection with the terminal verified earlier. The described process is repeated until there are unverified kayms, or all terminals are connected. In this case, the terminals with the corresponding bit in the number MEMO 0 are excluded from the analysis.

Due to the improved algorithm of the device’s operation and the ability to alphabetize it by outputting signals and reading information for common control modules, it also has wide functional possibilities, since the transistor block connection is prone to remove restrictions on the number of branches in the monitored installation.
