Description

The invention relates to the field of computer technology and can be used to control wiring diagrams of electronic equipment.

Devices for mounting verification are known, comprising an input unit, descriptors, a register, a circuit, combinations, a counter, and a control point changer unit. The device operates on the principle of sequential polling of control points of the wiring diagram. The disadvantage of these devices is the low | Some speed, due to the necessity of rocking the connection between each pair of points -.

Closest to the invention is a device 2 for monitoring wiring diagrams containing a block, to output information, an information input unit, a printing unit, an analysis unit, a memory block. Addresses, a comparison unit of 1 codes, two switching units and a fixation unit for yarns, connected by two-way communication with the control unit, with the input of the first block of the mutation connected to the input of the device, and the outputs to the nepiBbiM inputs of the second switching unit, the analysis unit and the voltage fixing unit, the output terminals of which are connected to the corresponding inputs bl Information output, the second outputs of the second switching unit and the fixing unit 1-: and the voltage and output of the information wiring unit are connected to the corresponding inputs of the comparison unit. The input of the information input unit is connected to the third output of the second switching unit.

The disadvantage of this device is its complexity, due to the need to use a large amount of memory to store the addresses of control points of the monitored wiring diagram.

The aim of the invention is to simplify the device. The goal is achieved by the fact that a block of control points and a comparison block are entered into the device, the control inputs of which are connected to the corresponding additional outputs of the control unit, the first and second inputs of the print unit are connected respectively to the first (Outputs | Blocks These are addresses and a control point counting block whose second outputs are (Connected to the corresponding inputs of the comparison block.

The drawing shows a block diagram of the proposed device.

It contains a control block 1, a print block 2, an information input block 3, an information output block 4, an analog block of 5 of analog, a comparison code block 6, a voltage clamp block 7, 8 L 9 switch blocks, a block 10

control points accounts, comparison block 11 And address memory block 12.

The device operates in two modes: program acquisition mode: We follow the reference product and mode (M checking the assembly of the manufactured Products according to the reference program. In both modes, the electrical connection is checked (each container of control points (contacts). To establish the installation Real addresses in block 12 enter information that takes into account the design features of the product: quantity (Contacts in the 1st connector of the control object AND its address (the module number of the object, the connector number in the module). The device (connect the reference object 13. / control provides a Reading from block 12 to a block // of the first word in which the number is written) to the contacts of the first connector, to the module this connector and the number of the connector are connected. The blocks 8 9 supply the voltage to the first contact of the first connector. According to the internal installation of the reference product, this voltage is applied to those contacts that are galvanically connected to the left contact. Then, the unit / starts the unit 7 of the phage and voltage and simultaneously the unit 10. The unit 7 determines all excited point mounting. The points of the Montage where the pressure is detected are analyzed, and their addresses through blocks 10 and 12 are output to block 2 for printing and block 4 (for example, to a perforator). After this, the next top level of the electrical circuit is excited and checked as it continues. In the // block, the code of the number of pins of the first connector is computed each step with the code in block 10. If these codes match, the block sends a signal to reset the block 10, and to the block // the second word (information about the second socket .me). Thus, the state of block 10 and.} In the form of a definite word of block 12 corresponds to the conditional block number poyoka.

In the mode of mounting the wand from the products of the standard product (program block / together with block 3 through the block 8 9. Is provided with the airborne switch and the contact on the object of control in accordance with the software: My,. Room on the carrier of the block 3, and, for example, a 1-strip tape. A block / starts block 7 and a block 10 at the same time. Block 7 analyzes all mounting points one by one for the presence of an excitation voltage.

and block / together with blocks // and 12 fixes their real addresses. The addresses of the mounting points at which voltage is detected, € p: av., Are analyzed and analyzed. 5 and 5, and in accordance with the results of the analysis, their real addresses along with the indications that "excess contact in the circuit or" lacking contact in the chain is issued for treatment. If, as a result of the analysis, you can see that there are no errors in the installation, then the check (continues until the detection of the bends. Thus, the invention can significantly reduce the amount of memory. For example, monitoring the object by 10 thousand points will ensure A device whose memory capacity is approximately 50 times smaller than a known device.
