The block diagram of the device shown in the drawing.

The device contains a remote control unit 1, a program block 2, a correction pulse generator 3, a variable-length pulse generator 4, a block

account adjustment 5, display unit 6, counter 7, command decoder 8, memory unit 9, second 10 and first 11 switches, Test voltage block 12, measurement block 13, connection test block 14, interface block 15 and Control object sixteen.

The device works as follows.

The beginning of the control is carried out by a command from the remote control 1, containing functionally generalized control agencies. The command arrives at block 2. In accordance with the selected program, in block 2, a control voltage is generated that acts on the decoder 8, in which the voltage is converted into a number of control actions, which.

arriving at the inputs of the switch U and block 6, they prepare a path for receiving and sending signals with a certain prize. on whom. At the same time from block 2 receives a command to the switch 11.

In the dialogue mode, under the influence of a command from block 2, switch 11 forms transmission circuits to switch 10 from block 12 or from block 15 of the electrical influences that are necessary to execute the selected control loop. In automatic and automated modes, switch 11 circuits are prepared npHeiyry automatic control commands.

1. In the automatic program control mode, switching circuits of signal sources coming from block 12 or from object 16 through block 15 to switch 10 are formed in the switch C. At the command from console 1, counter 7, generators 4 and 3 is turned on. 3. Generator 3 at the beginning Each monitoring cycle sends a correction signal B1 to counter 7, a pulse that determines the origin. Counter 7 generates commands in the form of a sequence of control pulses. The duration of which is determined by the generator 4. The control pulses from counter 7 arrive simultaneously at switch 10, at block b, and at a certain counting step specified by the program, at switch 11. Under the influence of control pulses switch 10 forms combinations of test polarity of a certain polarity and duration, which arrive at the input of block 15 and through the logical epi of object 16 to its information

In the case of ortdeparture, the counting cycle under the influence of the control pulse of the counter 7 in the switch 11 occurs and remembers the re-switching of the circuits connecting the sources of signals to the switch 10, which forms combinations of test messages with indications. Further switchings of the source signals are carried out analogously in accordance with the selected control program.

In block 6, the combination of test pulses is converted into indication signals, which are received by indicators of one of the information boards of the control panel and displayed on it according to the coordinate principle (group number, position number), which corresponds to the type and number of the circuit under test. Thus, a synchronous display of the process and results of the control is carried out on the information boards of the control device and the object being monitored. 2. In the automated mode, the device operates as follows a) when controlling logical control circuits, commands are received from the object 16, through block 15 This includes generator 3, generator 4 and counter 7. Counter 7 generates control pulses with a time delay, the origin of which is determined by generator 3. Control pulses From counter 7 to step on the inputs of the switches 10 and 11 Under the influence of the control pulse of the counter 7, the switch 11 (remembers) overloads the connection of the signal sources to the switch 10, which forms combinations of response test messages, which through unit 15 arrive at the object's 16 mimic diagram. b) In the test control of the signaling paths, the device works in a similar way. Counter 7 generates a series of control pulses without idlers and turns off at a certain counting clock specified by the monitoring program, after which the next receipt of commands from the object 16 is possible. Block 5 ensures that the counting process at any of its cycles is possible both in manual and in automatic. c) When monitoring the formation of the switching paths, the inputs and outputs of the switching device of the object 16 are connected via block 15 to block 14. In this case, each circuit of the switching path is connected to a control logic circuit. These logical circuits provide a display on the information board of the control panel 1 of the state of each switching cell. When a power command is received from i i in block 14, power is supplied to the logical control circuits received from 12 via the switch 11. When the switching path is formed at the object 16, the logic circuits and issue information about the switching state on the information board 1. According to the control commands from the console 1, the counter 7 is activated and forms a series of control pulses, which, on the switch 11, carry out a series connection of the power supply to the logical circuits of the control of the switched path. Thus, individual control of each circuit of the switching cell is carried out. The control of the loops formed in the object 16 is performed by block 13. The connection of the loop to block 13 is performed by a command from the console 1, which enters block 14. In the dialogue mode, the switch 11 is controlled from block 2 and the signal source connection circuits are formed in it This test cycle simultaneously. In this mode, block 15, by means of re-switching, connects the control paths of object 16 to be monitored. Single or two-coordinate commands acting on these paths affect switch Yu and block 6. Switch 1O forms paths for passing single and group test signals from block 12 (or through block 15) through switch 11. Test signals from switch 10 with the required level through block 15 they are received at controlled points and, in case of serviceability, on pneumatic circuits and scoreboard of object 16. By means of re-switching, unit 15 sequentially connects to control all circuits and paths of object 16, pre given a given prog | () amma control. UNIT 6 synchronously with the issuance of test signals, it sends 1 received commands to the control of information panels on the console. Thus, the reception and transmission of signals is carried out synchronously. The positive effect of the invention is that the device for monitoring the control devices allows for a comprehensive check of the operation of the control equipment by simulating the control complex of the objects. This significantly reduces the cost of monitoring and test equipment. In addition, the device provides automation of the process control and an in-depth display of the results of the control, allows you to completely eliminate manual operations, creates safe and safe working conditions.
