The device works as follows.

The operation of the device in the control mode is based on the receipt of individual convolutions of individual wires on the signature analyzer 8 and an azimatical convolution, independent of the order in which the private convolutions arrive, on the accumulating adder of elements 15, 16 and 17. All toggle switches 44.1-44. Simulator h in this case is disabled.

When the button 20 is pressed, the control unit 7 generates a signal of the initial state, according to which the counter 2, the register 17 and the trigger 31 in the control unit 7 are set to the cool state. After a time, (via element 34 OR, delay element 25), control unit 7 outputs a signal that overwrites the zero state of counter 2 to counter 3, and after a time (control unit 7 adds unit to counter 3, through delay element 26. The next signal from control unit 7 through time (through delay element 27) the state of counter 3 is entered through valve block 11 into signature analyzer 8.

The decoder 4 decrypts the zero state of the counter 2 and on - and the contact of the object I the claws sets the unit. In accordance with the connections in the object 1, this e; p1INits passes to the corresponding other contacts of the object 1 and enters the inputs of the multiplexer 5. The latter connects to the element 6 i + 1 a contact. If there is no connection between the i-th and 1 + 1-st contacts, then the logical zero arrives at the input of element 6, and if there is a connection, then one.

When the button 21 is pressed, the triggers 14 and 31 are set to single states and, via element 32 I, allow the generator 33 to generate two sequences of pulses t and tj shifted relative to each other. One pulse t analyzes the presence of a unit at the input of element 6, i.e. checks for a connection between pin 1 and j. One pulse 12 shifts the signature analyzer 8 by one clock and adds 3 units to the counter, i.e. through multiplexer 5 connects the next contact number of the object

1. Adding units to counter 3 and shifting information in the signature analyzer 8 occurs until the output of element 6 fails to generate a pulse signaling the presence of a connection in the object 1. Through this pulse, which passed through element 12 OR, the trigger 14 is reset to the zero state and through the element 32 and blocks the generator 33. Simultaneously, the counter 2 is switched and the state of the counter 2 is written to the counter 3 after a time (through the delay element 23), and the state is entered of this counter in signal urny analyzer 8 via the valve unit 11. The same pulse from the output of the element 6 And through the element 13 OR produces the input of the contents of the signature analyzer 8 through the adder 15 and the switch 16 into the register 17. In this case, the switch 19 polar

The code is set by the toggle switch 24 to the direct code, and the switch 16 is set by the toggle switch 23 to transfer information to the register 17 from the adder 15.

As a result, in register 17 there is a recorded private signature characterizing the connection between two contacts and j of object 1, the position of contact i is characterized by the initial state of counter 3 (before the beginning of the polling of the states of object 1), and the length of the connection is characterized by the number of shift cycles, specified from the control unit 7 to the signature analyzer 8, the number of which is equal to the number of contacts of the object 1 located between contacts 1 and j and not connected to the contact, in which case the counter 2 and the counter 3 are recorded contact time + and +1, I

After a time of about, + cr + a signal from the output of control unit 7 (through delay element 29, element 35 OR reset the trigger 14 to the state of one and through element 32 And the generator is unlocked and will continue to process the sequence of pulses t, and tg.

With the appearance of a single logic level at the output of element 6 AND, indicating the presence of a connection between the contacts 1 + 1 and j + K

of object 1, it is transmitted through element 3 OR to the control input of register 17, which receives for storage the sum of the private signature

J of the i-th contact with the private signature of the i + 1-st contact. The sum of the private signatures is obtained in the combinational adder 15, which receives the signature of the i-th contact with the output

10 register 17 and signature 5 contact with the output of the analyzer analyzer 8.

After that, the device proceeds to polling the f + 2 nd communications and the remaining 5 contacts of object 1.

As a result of the operation of the device of each electrical connection of the two contacts 1 and J of the object I, its private signal is assigned to each other, and all private signatures are summed by a accumulating adder on the elements 15, 16 and 17.

The next signal of the presence of a connection from the output of element 6 And adds .25 information to the accumulating adder on elements 15, 16 and 17.

The switching of the counter 2 occurs not only in the case of detection of a connection by the element 6 of the analysis, but also

If there is no communication due to the overflow pulse from counter 3. The final shutdown of the device operation will occur at the overflow signal from counter 2, coming through element 30 OR to the trigger input 31

 and blocking the generator 33. The indicator 9 fixes on its display a total assembly convolution (signatures.

Since the total signature of object I consists of the sums of private signatures of individual bonds of pairs of contacts n, it is possible, by excluding and adding links in object 1 of the control, to obtain the corrected total signature signature without using object 1. To do this, on the simulator 10 connections, including the required toggle switches 44.1- 44.P in turn dial up the connection connections), which are subject to withdrawal. Using the toggle switch 24, set the switch 19 of the polarity of the code to issue a reverse code, which leads to subtraction from the number written in register 17,

55 numbers coming from the signature analyzer 8 in accumulative adder 15. On the toggle switch 18 signatures obtained with

40

The initial survey of object 1, type the value of the signature. Using the toggle switch 23, the switch 16 is set up for information transfer and the toggle setter 18 of the signature. Press the button 22, which leads to the input of a given signature in the register 17. Turn off the toggle switch 23. Press the button 21.

As a result of polling with the help of counters 2 and 3 and the multiplexer 5 of the simulator's communications in the signature analyzer 8, private signatures of the excluded links are obtained, which are inverted in the polarity switch 19, in the reverse code are fed to a combination adder 15, where they are subtracted from recorded in register 17. The result of the signal subtraction from element 6 is through element 13 OR is written to register 17.

After that, on the simulator 10, by turning on the corresponding toggle switches, new connections are taken up in turn. The switch 24 adjusts the switch 19 of the polarity of the code for the input of the direct code. The button 21 is pressed. As a result, the accumulating adder on the elements 15, 16 and 17 adds new partial signatures to the intermediate result and the total assembly convolution is corrected. This allows one to obtain a total convolution without waiting for the modifications of the devices being tested.

Signature analyzer 8 works as follows.

The information inputs of the shift register 37 receive the counter code 3, which identifies the I and the object contour 1. The signals from the control unit 7 shift this code and write to the first bit of the shift register 37 modulo two, register states

37, which allows us to associate each signature with its signature convolution, depending on this and on the number of shear cycles, i.e. from the position of contact j electrically connected to contact | .

The simulator 10 connections works as follows. 0 The inclusion of a pair of toggle switches 44.d and 44.J simulates the connection between any pair of contacts i, object 1, whose private signature is either added or subtracted from the total 5 signatures depending on the position 24 of the control unit 7.

The switch 19 polarity code works as follows.

Depending on the signal of the control block 0 7, the signals from the signature analyzer 8 pass through the elements 43.1-43.h 2И-OR to the combinational adder 15 without inversion or after inversion on the element 5 like 41.1-41.P. Element 42 does NOT control the operation of elements 43.1-43.P 2I-OR. Block 11 valves contains elements 38-. 1-38. and and 39.1- 39.p. AND-NOT elements that give out

0 at the output of block 11 by the signal from

block 7 control direct and inverse codes of the counter 3,

Thus, the introduction into the simulator 10 device of the unit 11 ventilators, elements 12 and 13 OR, trigger 14 of the ring combinational adder 15, information switch 16, static register 17, toggle setting device 18 of the signal type and code switch 19 allows to obtain the total a signature convolution consisting of the sum of the private signatures of the individual links, and promptly correcting the result of the overall convolution without an existing reference, which significantly expands the functionality of the device.
