Block 1 is designed to generate control signals for blocks 3, 4, 6, 7, 8, 10, and 11. The first inputs of block 1 are the signals Spr (signal tracking) and exchange) with; the second outputs of the ACU 2, to the second input of which a CRC signal is sent (Confirmation) from the first output of block 1. Signals Ref. Then, PT and are intended to synchronize the exchange of information between the Q UVM 2 and block 1. To the first inputs of block 1, the address code from the information address bus 1 of the UVM (first outputs of the UVM) is fed through the block 5 of the address registers that determines the number 5 of the second output unit 1, where the control signal is installed.

In quality of UVM 2 any serial micro-mini-computer can be used, for example Electronics-60, CM-1800,

The input information registers are assigned to store the binary codes used to control the stimulus blocks 7 and generate digital stimulus signals for testing the control object 9. Writing data to registers 3 arriving at their first inputs from the information address bus produces Q with control signals arriving at the second inputs of registers 3 from synchronization unit 1.

Output registers are used to store the results.

Synchronization of information between the block 5 and the ACM is made using the signals Sp.t. ,.P.p. transferred over the bus connecting the second jj inputs and outputs of the block 5 address registers and the second inputs and outputs of the ACU 2. The first switch 6 is designed for switching the inputs-outputs of the control object 5 to the corresponding outputs of blocks 3 and 7 and inputs blocks 4 and 8. Relays included in the first comm ator 6, are controlled by switching the register (at block is gory

The codes of the sources of stimulating signals included in block 7, with de-energized relays 17, 18 and 22, are connected to the inputs of the corresponding meters of block 8, which allows self-control of blocks 7 and 8.

characteristics of the parameters of the object 9 control and the results of the system self-control operations. The third inputs of the block receive signals ZPR1-VNSH (External interrupt request), which are generated by the analysis unit 15 at the end of measurement of the parameters of the object 9 of the control unit 8 meters, as well as when faults are detected in blocks 7 and 8. When an external interrupt request unit 10 generates a signal ZPR1 (interrupt request), which from the second output goes to the third input of the ACU 2. In response to this signal, the ACU 2 outputs a P3PI (Enable interrupt) signal coming from the third output of the ACU 2 to the second input of the block 10. Next to the third outputs, an interrupt vector is generated, indicating the address of the UVM memory cell with the beginning of the program intended to process the external interrupt request having the highest priority. According to the signal from the synchronization unit t, the interrupt vector from the unit 10 is inputted to the ACU 2.

the switch 11 is input to the ACU 2, where a comparison is made with control codes.

As an output unit 12, a standard alphanumeric printing device (ADC) is used to print the results of an object control,

As the terminal 13, a video terminal (display) is used for the current control of the monitoring modes.

Unit 14 is intended for comparing codes from input registers 3 to control inputs of stimulating sources 7 with codes at the output of corresponding meters included in block 8 in the autocontrol mode. If the mismatch of these codes does not exceed the specified tolerance, then a signal corresponding to a logical zero is set at the corresponding output of block 14; otherwise, a logical one. de.

The analysis unit 15 is designed to generate signals of the PRD1-VNSH (External interrupt request) at the end of the next cycle of measuring the OK parameters and performing the self-monitoring of blocks 7 and 8. The first inputs of the AND elements of group 23 receive signals from the corresponding outputs of the comparison unit, and the second (inverse) - signals from the outputs of the switching register, located in block 3 of the information registers, and through which the relay 18 of the first switch 6 is controlled (Fig. 2), This or that pair is a source of stimulating vii - the meter is in the autocontrol mode, if the contacts of the relay 18 are in the lower position (the source of the stimulating effect is connected to the input of the corresponding meter), and are in the mode of control of the object parameters, if the contacts of the relay 18 are in the upper position, T, e, the output-register of the switching, the control of the state of the relay 18, takes the value O, if the corresponding pair of source of stimulating influences — the meter is in the autocontrol mode, and the value .1, if carried out, the pairs are controlled ters object. Then from the scheme (fig.Z) it follows that

Level 1 at the D-input of trigger group 25 can be set in two cases. In the first case, this pair is a source of stimulating effects — the meter is in the auto-control mode and the difference in codes between the input of the stimulus and the input

 the meter exceeds the set tolerance, which leads to the installation of the signal 1 at the corresponding output of the comparator unit 14. In another case, this pair is a source of stimulating

Impact - the meter is in the mode of monitoring the parameters of the object. The triggers of group 25 take the D-input state when the C (synchronization) pulse C (End of measurement) passes from the output of the corresponding meter. Thus, the signal ZPR-VNSH at the output of the trigger; group 25 is set in two cases: the next cycle of monitoring the object parameters is completed, or in case of detection of faults in the source of stimuli or meter, which are in the autocontrol mode. Reset. group triggers

25 is reset to its original state using signals from synchronization unit 1.

The device works as follows

In accordance with the program stored in the storage device UVM 2, the information address bus UVM at the inputs of the registers 3 input

information are sequentially installed the necessary data that determines the level of the signals set at the output of the block; 7 stimulating signals, as well as modes in which

the corresponding source of stimulus pairs are the meter (the mode is set by switching on the corresponding relays in the switch 6). These data are sequentially recorded in the input information registers 3 by the signals from the synchronization unit 1. The addresses of the input information registers 3, in which data are written from the information address bus UVM (first inputs and outputs UVM) are preliminarily entered in block 5 of the address registers. Address decoding is performed by synchronization unit 1.

Under the influence of codes recorded in registers 3, the necessary switching of circuits is performed using a switch 6 and the installation of the necessary signals at the output of block 7 of stimulating influences.

Then, from the synchronization unit 1, a control signal is supplied to the first input of the measuring unit, / which is combined with the triggering inputs of all the meters included in the unit 8. The values of the parameters of the object 9 effects - the meter is in the mode of controlling the parameters of the object) or signal signals at the output of the block of stimulating signals (if this pair is the source of stimulating effects - the meter is in the autocontrol mode).

Since the measurement time of the parameters of the signals by the block 8 is long compared to the computer cycle of the ACU, during the measurement of the parameters, the previous measurements are processed, the next ones are prepared, and the data recorded in the input information registers 3 are self-monitored by entering these data back in UVM 2 via the second switch 11 where they are compared with the control codes.

The codes supplied to the control INPUTS of the sources of stimulating effects of block 7 are compared with the output codes of the corresponding meters of block 8 using the block 14 of the comparison. Comparison results are received from the output of block 14 to the first inputs of block 15 of analysis, the output of which produces signals GPRH-VNSh when the signals of Ki (End of measurement) come to its third inputs from the second outputs of meters 8, if these meters are used for measuring object parameters 9 control. Signals SSP1-VNSH at the output of block 15 are also formed in the case when the values of the codes at the input and output of the corresponding pair of stimulating source — the meter, which are in the autocontrol mode, differ by an amount exceeding a predetermined tolerance.

Signals ЗПР1-ВНШ from the output of the block 15 are fed to the input of the block 10 of the control mode II, which forms Za18 10

interrupt request (RFR1), which arrives at the third input of the power supply control unit, in response to which the power supply control unit sets the third output signal to the Interrupt Enable (PSPi). On this signal, block 10 sets up an interrupt vector indicating the cell of the ACU with the start of the program for processing an external interrupt request that has the highest priority. In the course of this program, information is being retrieved from the outputs of the output information registers, in which the measurement results from block 8 are recorded when the fourth inputs of registers 4 signals C (End of measurement) are received from the outputs of block 8 meters. After processing the measurement results in UVM, they are output to print (block 12 output). Changing the sequence of program execution, its looping, stopping, resuming execution is performed from the terminal 13 using the directives of the real-time operating system (RT OS).

To feed the digital code control object, the contacts of the relay 17 and 22 of the first switch 1 are moved to the upper position. In this case, the code from the output of the input information registers is fed to the inputs of the corresponding output information registers 4, which is then entered into the ACU, where it is compared with the control ones. Further, the contacts of the relay 18 of the first switch 6 are shifted to the position, and by transferring the contacts of the corresponding relays 20 to the lower position, the digital signals are fed to the input of the control object. The digital outputs of the control object are connected to the inputs of the registers 4 of the output information by transferring to the lower position of the contacts of the corresponding relays 21. After writing the registers 4 of the digital code from the control object, it is entered into the DCA. The control of the correct operation of the relay of the first switch 6 is performed by periodically polling (after each change of the relay switch state 1) the switching register included in block 3 using the second switch 11.

Thus, the process of controlling the parameters of an object is carried out simultaneously with the operation of the autocontrol of sources of stimulating effects.

and meters that are not used at a given moment in time to apply actions to the object of control and measure its parameters. Taking into account that the process of measuring parameters and effects using meters is the longest compared to; other operations that are carried out in the system, combining in time the operations of measuring the parameters of the object and the operations of self-monitoring allows to improve the performance of the device.

The device also allows one to apply influences on an object of control from several sources of stimulating effects simultaneously and, accordingly, to make measurements of parameters at several points of the object of control.

In addition, the device allows for the automatic control of almost all blocks of the system, which allows to increase the reliability of the results
