The disadvantage of this device is the necessity of using the PC and switch channels, which leads to a long-time inspection of the test object due to the necessity of the connection of the specified equipment, software downloads, and perform additional operations on the PC in the review process. Also a disadvantage is the need to purchase, transport, storage and repair, in addition to the block control circuits, additional hardware.

The objective of the proposed invention is to eliminate these disadvantages, increasing operationalerror object of control by optimizing the applied hardware the increased automation of process control.

To achieve the specified result in AKPA, containing multi-block comparison, United with him the virtual pattern and the block normalization, a multiplexer, connected to its inputs with the output circuits of the control object, the switch is connected by its inputs to the outputs of the multiplexer, and outputs to the inputs of the block normalization, the shaper output signals are connected by their outputs to the input circuits of the control object and the input of the multiplexer, a control unit connected to the multi-unit comparison, a virtual standard switch and driver output signals entered connected to the control unit driver type TSA, the storage unit sets the standards, the storage unit control results indicator of good condition, with all parts of the device are combined in the control unit circuits, and the block normalization is made in the form of a voltage meter and meter circuit, whose inputs are connected to outputs of the switch, and outputs - inputs multi-Comparer.

In the particular case of the ACP contains at least two blocks of the control circuits.

In the particular case for pre-programming of control unit circuits and the read control results at the end of the test work may enter Uchenie to it technology PC.

The invention is illustrated by figure 1, which presents a block diagram of the device.

The ACP consists of one or more units 3 control circuits, which are connected to the output and input circuits of the object 2 control. Each of the blocks 3 of the control circuit consists of a control unit 4, microprocessor-based or microcontroller, multi-unit 5 comparison made on the basis of a microcontroller or a programmable logic IC, virtual reference 6, is made on the basis of RAM, switch 7, which is made on the basis of electronic keys, driver 8 output signals produced on the base of transistor switches, optocouplers, operational amplifiers, etc., a multiplexer 9, which is made on the basis of specialized IC block normalization 10, consisting of meter 11 voltage and measuring circuit 12, is made on the basis of ADC driver 13 type TSA made on the basis of mechanical switches (switches, disk switches and the like), block 14 storing a set of samples and the unit 15 to store the results of monitoring done on the basis of the chip non-volatile memory (e.g. flash memory), indicator 16 health, made on the basis of LEDs, indicator lamps, etc.

The GEARBOX works as follows.

Units 3 control circuits connected to about the project, 2 control. Using the shaper 13 type TSA operator specifies the desired type of TSA, installing mechanical switches in the relevant provisions.

Selected TSA is analyzed by the control unit 4, which reads from the storage unit 15 of the standards appropriate set of commands for checking circuits, sorts the received command on the destination and sends them to the virtual reference 6 and the imaging unit 8 output signals.

Virtual reference 6 on the basis of the received command generates and transmits a multi-line block 5 comparison signals, the magnitude of the voltage corresponding to the signals of the controlled circuits in digital form during their normal operation.

Driver 8 output signals according to commands from the control unit 4 generates at its outputs and transmits to the input circuit of the object 2 of the control pulse and analog signals, the magnitude of the voltage corresponding to the pulse and analog signals interacting with the circuits of the controlled object. The same signals from the imaging unit 8 transmits output signals to the multiplexer 9 and then through the switch 7 to the inputs of the block 10 normalization in accordance with the commands of the control unit 4. Unit 10 the normalization converts the received pulse and analog signals to digital and sends them to a multi-line block 5 compare, where they are compared with the signals is, which should be generated at the outputs of the driver 8 output signals in accordance with a given program verification. The results of the comparison are transmitted to the control unit 4 which performs operation control of the imaging unit 8 output signals. In case of unacceptable deviations of the values of the signals generated by the imaging unit 8 output signals from the values that were to be formed, the control unit 4 stops the operation of the imaging unit 8 output signals.

Then, the multiplexer 9 receives at its inputs the signals from the output circuits of the object 2 control and passes them through the switch 7 to the inputs of the block 10 normalization in accordance with the commands of the control unit 4.

Unit 10 the normalization converts the received pulse and analog signals to digital and sends them to a multi-line block 5 compare, where they are compared with the signals from the virtual reference 6, in real time. Unit 10 the normalization includes meter 11 voltage, determining and converting into digital form the voltage coming from the output circuits of the object 2 control and measuring circuit 12, the incoming signals defining features or no break in one way or another circuit, and converts this information into a digital code. The results of the comparison signals, postupaesh the x from block 10 normalization, with the signals from the virtual reference 6, are transmitted multi-channel unit 5 comparing to the control unit 4. On the basis of the received processing results (comparison) signals the control unit 4 decides on the validity of object 2 and issues appropriate control signals to the indicator 16 health for visualization of the inspection results (pass/fail), while the detailed results of the control (including the value given and accepted in the process control signals) are also stored in the storage unit 15 of the control results.

If necessary, to the unit 3 control circuits may connect technology PC 1 prior to the commencement of tests) records standards in non-volatile memory block 14 storing a set of samples, as well as to read inspection results stored in the course of the audit, from the storage unit 15 of the control results for subsequent analysis. Technology PC 1 is connected with the unit 3 control circuits through a standard digital interface (e.g. USB, RS-422, and so on).

Thus, due to the fact that the device has entered the imaging unit 13 type of TSA, block 14 storing a set of samples, the storage unit 15 of the control results and the indicator 16 health with corresponding connections, the result is excluded from the process control PC and commutate the R channel, achieved significant reduction in scan time of the inspection object and decreases the amount used in the process control hardware.
