In these devices, with a strict sequence of controlled mounting points, specified first

15, if there is a controlled point connection with another point, this connection is fixed and the transition to the next point is polled. In this case, fixing the results

The control 20 is not made in the address range specified in the connection table, which increases the time and complicates the handling of the rezlu. 3.9 tatov control. The lack of operational control of the operation of the first decoder and the analysis unit, as the most complex components of the device in the event of their failure, leads to incorrect results of testing the product. In addition, if there are connectors with a combined, for example, alphanumeric contact pin, in the tested product, the recorded control results do not correspond to their designation given in the documentation and require additional time for their decoding.

The drawbacks of this device are low reliability and long monitoring time, as when testing products with connectors with a combined contact designation, for example, with alphanumeric (RP-14, GRPM connectors), the control results are not fixed according to their designations given in the connection table and the electrical drawing of the product, which necessitates additional time and stimulates the appearance of errors of a subjective nature in the subsequent manual decoding monitoring results to actuate them in accordance with designations of the compounds in the table and the drawing wiring. The aim of the invention is to reduce the duration of control and increase the reliability of the verification of installation. The goal is achieved in that a device for checking the installation, containing a register, whose outputs are connected to a group of inputs of an output unit, a pulse generator, an analysis unit, X and Y coordinate decoders, X and Y coordinate counters, a comparison unit and an output control unit, the output of the pulse generator is connected to the counting input of the counter of the X coordinate, the output of the analysis block is connected to the control input of the comparison unit, the output group of the counter of the X coordinate is connected to the inputs of the decoder of the X coordinate and to the first group of inputs of the block the comparison, the output group of the Y coordinate counter is connected to the output group of the device, to the decoder inputs of the Y coordinate and to the second input block of the comparison unit, the first output of which is connected to the quenching input of the X coordinate counter, and the second output to the control input of the output control unit, the first the output groups of the decoder coordinates X and Y are respectively connected to the first and second groups of inputs of the analysis unit, the outputs of the output control unit are connected respectively to

Figure 1 shows the functional diagram of the device for checking the installation; Figures 2-6 are examples of the execution of an output control block, a setpoint switch, a yn-i switch of the matching signal, an analysis unit, a comparison unit, respectively.

The device for checking the assembly contains (Fig. 1) an output block 1, a register 2, a block for X coding, a block for encoding a Y coordinate, a block 5 of output control, a block 6 for analysis, a decoder 7 for X coordinate, a block 8 for comparison, a decoder 9 for Y coordinate , generator 10 pulses, counter 11 coordinates X, counter 12 coordinates Y, counters 13 module groups, counters W groups, switches 15 control signal, switches 16 setpoint. The output control unit 5 contains (FIG. 2) a pulse generator 17, an AND 18 element, a clock distributor 19 and a trigger 20. The setpoint switches 16 contain diode coders 21 (FIG. 3); the switches 15 contain (FIG.) AND elements 22 and the OR element 23, the analysis unit, 6 contains (FIG. 5) the elements AND 2 and the element OR 25. The comparison unit contains the comparison schemes 26-28, the element OR 29, the elements AND 30-32 and the element NOT 33 (FIG. 6).

The device works as follows.

When using connectors with a combined (alphanumeric) pin designation in switches 16, for each connector of the product a cipher is installed defining a recalculation module equal to or greater than the number of contacts in each of the groups of con tacts, denoted by letter index. From the output of the generator 10 to the counting input of the counter 11 and the counting input of the counter 13 enters the trigger frequency. Overflow signals from the output of counter 11 follow to the counting inputs of counters 12 and counter 13 of block k. Changing the codes for the addresses of the X and Y coordinates from the outputs of the meters 11 and 12, respectively, go to the inputs of the decoder 7 and 9 and to the groups of inputs of block 8. The current decoded value of the X coordinate goes to the first group of inputs of the 6, and the Y coordinates to the second group of inputs unit 6 and to the test product. The current decrypted value of the slot number of the X coordinate goes to the input group of block 3 and register 2, and the value of the contact number of the X coordinate goes to another input group of block 3. The current decoded value of the slot number of the Y coordinate with B IXOAOB decoder 9 goes to the first group of block inputs and on the group of inputs of register 2, and the value of the number of contacts of the coordinate Y - on the second group of inputs of the block. On the switches 16 for the current values of the number of connectors of the X and Y coordinates, signals are generated that correspond to the installed recalculation module, depending on the constructive performance of the connectors. For example, for the GRPM2-62 connector (k

7.9

the groups with the designation A1 -A (5; B1 -B16 B1-815; G1-G16) generate a signal corresponding to the conversion module equal to 16, for (FP1 4-10 output (2 groups with the designation A1-L5, BIBS) a signal is generated, corresponding to the recalculation module equal to 8. If these signals coincide with the corresponding current value of the contact number at the outputs of the decoders 7 and 9, the switches 15 carry out the damping of the counters 13, from the outputs of which the signals arrive at the counting input of the counters 1A. generating output codes corresponding to the const If there is a connection in the item under test, determined by the decrypted values of counters 11 and 12, a signal is generated at the output of block 6, which is transmitted to the control input of block 8. In the case where the address code X is greater than the address code Y coordinate 8 transmits a signal of the presence of a connection to the control input of block 5. At that, block 5 stops the generator 10 for the time of fixing the addresses in register 2 from the output of counters 13 and 11 and decoders 7 and 9 and outputting 8 block 1 fixed on register 2 a ests compound. Then, block 5, to continue operation of the device, starts the generator 10. When there is a signal at the control input of block 8, when the address code of the X coordinate is less than the address code of the Y coordinate, block 8 generates a signal transmitted to the blanking input of the counter 11 and counting inputs counter 12 and counter 13 block. In the absence of a signal at the control input of block 8, if the codes on counters 11 and 12 are equal, block 8 produces a signal that detects a malfunction of the analysis unit. When using connectors with digital contact designation in the product being tested, the order of operation of the device is similar. The difference is that the counter recalculation module 13 is set to the maximum and a commander 15 does not generate a control signal.

Each switch 16 contains a group of diode encoders 21, in each of which the code of the recalculation module of the corresponding connector is installed by means of a diode. Number 8228

In 1.1 of the inverters, 21 is determined by the number of connectors that make up the product being used. The signals arriving at the information inputs pass through the corresponding diodes of the encoders and are allocated at the corresponding output of the switch. Switches 15 form a signal at the output of the element OR 23 with bit size

0 coincidence on elements AND 22 signals arriving at their inputs, i.e. if the installed recalculation module matches the current value of the contact number. Block 6 structure

5 analysis is similar to the structure of the control signal switches 15. The number of elements And 2 is equal to the number of pins of the connectors of the tested product. The signal from the output element

0 OR 25 is allocated when one of the elements AND 2k of the decrypted signal coincides with the X coordinate and the decrypted signal of the Y coordinate, received either through the corresponding connection of the test product or directly from the decoder of the Y coordinate 9 if the X and Y addresses are equal,

The cycle of operation of the control unit 5

0 output begins when a signal arrives at the installation input of the trigger unit 20 (FIG. 2) - The pulses from the generator 17 output through the AND 18 element arrive at the input of the distributor 13 cycles, which forms a sequence of signals that alternately excite each of the output buses. The last of the signals of the distributor 19 sets the trigger 20 to the state of logical zero, thereby prohibiting the passage of pulses from the output of the generator 17 to the input of the distributor 19.

The input of the comparison unit 8 receives the multi-bit address codes X and Y, which are transmitted to the input of the comparison circuits. The comparison circuit 2b generates a signal when the code entering the first group of inputs is greater than

JJ code arriving at the second group of inputs of block 8. Comparison circuit 27 generates a signal when the ratio of these codes is opposite, and the 28 comparison circuit is equal if the specified codes are equal. The signal from the control input of the block 8 is fed to the elements 30 and 31 and through the element NOT 33 to the element 32. At the same time, to the first output of the block 8, the signal comes from the output of the element 31. and the second exit through the element OR 29.
