The drawing shows the functional

15 scheme of the dispatching half-set of the telemechanical device.

The dispatching half-set consists of the distributor .1 with the address and working parts, the autorun unit 2, the imaging unit 3

20 clocks, block 4 of the transmission of a clock pulse, block 5 of the transmission of commands, block 6 of control keys, block 7 of receiving signals, call triggers 8, control elements AND 9, block AND 10 of the prohibition, address elements

25 AND 11, common-law element AND 12, first 13 and second 14 elements OR, registration blocks 15, signal elements AND 16, control triggers 17, elements OR 18 objects corresponding to objects at the controlled point, triggers 19 objects corresponding to objects at the controlled point , element OR .20, element AND 21 of a call, element NOT 22, element AND 23 of a reset, register 24 into five cells, limiter

5 (diode) 25 and the counter 26.

The device works as follows. In the first cell of the distributor 1, a unit is recorded by the autorun unit 2. The advancement of the unit is accomplished by a 3 clock shaper. At the last operation cycle of the distributor 1 an impulse is output to the unit.

4 sync pulse transmissions. The sync pulse enters the communication line, is received at the controlled points and records the output in

5 the first cell of distributors of controlled items (the scheme of the controlled item is not shown in the drawing). In the duty mode, the duty pulses come from the monitored points, and in the operating mode - signaling pulses about the state of the objects on the called monitored item. The absence of the impulse of the duty mode at any step of the address part of the distributor 1 indicates that at the corresponding control point there is a change in the state of the objects. The call of the controlled point is carried out automatically with the help of the block

5 transmission of commands, it is also possible with the help of block 6 of control keys / that affect the block b of command transmission.

Let, for example, there be a change in the state of the object on the first controlled point. Then at the tact of operation of the first cell of the distributor 1, at the input of the reception unit 7

signals there is no impulse of the duty mode of the first controlled item. At the second output of the signal receiving unit 7, a pulse appears at the first clock cycle, which the first trigger 8 of the call through the first control element AND9 appears. As a result, the rest of the call trigger triggers 8 and the other clock cycles of the distributor 1 are prohibited from the And 10 element. The first call trigger 8 is executed by the first address element AND 11 and the common element AND 12 through the element OR 13. In the next cycle of operation of the distributor 1 to the communication line from the first element And 11 and the general caller element AND 12 through the element OR 14 and. Block 5 transmissions of commands receive a series of ringing pulses, which co-costs from them: the pulses of the number of the first controlled item and the general calling pulse. As a result of this, the first monitored item is transferred to the operating mode and sends to the communication line pulses of signaling signals about the state of objects. The pulses of signaling the state of objects at the first controlled point are received by the signal receiving unit 7 at the working part of the explorer 1 and recorded in the first registration unit 15 through the first signal elements AND 16. The signal elements AND 16 are prepared to be activated first control trigger 17, which is raised from the pulse from the output of the first address element AND 11. The signaling pulses of the state of the objects of the first co-controlled point from the outputs of the first signal element AND 16 are also given through the corresponding Corresponding elements OR 18 objects to the counting inputs. the triggers of the 19 objects that previously were in the initial reset state and with their zero outputs affected the inputs of the third element OR 20. The object triggers corresponding to the enabled objects are activated and the disabled objects remain in the reset state. As a result, the output of the element OR 20 is a single notional, which is prepared for resetting the first input of the call element 21 and affects the input of the element NOT 22. The output of the element 22 will have a zero potential that is fed to the second input of the element 23 And reset. The element And 23 does not reset, and the first trigger 8 of the call remains in the cocked state. This leads to the fact that in the next dispenser operation cycle occurs (Recalling the first controlled item. The pulse of the number of the first controlled item resets the first registration block 15 to the initial state. In addition, the pulse number of the first controlled item from the first address element I 11 and the impulse from the general calling element AND 12 through the element OR 14 acts on the second input of the element AND of the call 21. The element And, 21 of the repeated call prepared by the element OR 20, operates twice and generates two pulses Register 24. In the initial state, the unit 1 is recorded in the first cell of the register 24. At the output of the third cell of the register 24, there appears a single potential that prepares the reset element I 23. For the second input of the AND element 23 the zero loss of element. NOT 22. At the working time of the working part of the distributor 1, the signaling pulses from the outputs, the first signal elements AND 16 through the elements OR 18 objects again act on the counting inputs of the triggers of 19 objects. If the callback signaling pulses are identical to the first-call pulse, then all the triggers of the 19 objects are returned to their original reset state. There are zero potentials at all inputs of the third element OR 20, and also zero potential at its output. This zero potential prevents the triggering of the call element AND 21 and affects the output of the HE element 22, at the output of which a unit potential appears, which triggers the AND 23 release element. Element I 23 triggers and resets the first call trigger 8 and register 24. The call to the first controlled item is stopped and in the first register unit 15 there remains an object state record at the repeated call that is identical to the one recorded at the first call. If the callback signaling pulses are not identical to the signaling signal of the first call, then some of the triggers of the 19 objects remain in the cocked state. At the output of the third element OR 20, the unit potential also remains, and at the output of the element HE 22 — zero. Element And 23 does not work and reset of 8-point triggers does not occur. The nerve controlled item is called for the third time. The pulses of the call of the first controlled point again act through the element 21 on the input of the register 24, and it shifts another two cells. The impulse from the input of the cell of the register 24 resets the triggers 19 and writes the unit to the first cell of the register 24. The reset of the call triggers 8 is prevented by the limiter 25. In the third call, the signaling pulses from the first controlled point again act on the counting inputs of the trigger 19 objects. Object triggers corresponding to the enabled state of the objects are cocked. At the output of the element OR 20, a single potential appears, which prohibits through the element NOT 22 the operation of the element AND 23 of the reset. The first call trigger 8 is not reset, and the first monitored item is called for the fourth time. When the first controlled item is called for the fourth time, the pulses from the first address element AND1 and the general call element AND 12 through the element OR 14 and the call element And 21 again affect the input of the register 24. In register 24, the unit is shifted by two cells. As a result, at the output of the third cell of the register 24, io is a single potential that prepares for the first input element AND 23 of the reset. At the working hours of the working part of the distributor I., signaling pulses are received. If the signaling pulses of the fourth call are identical to the signaling pulses of the third call, then the object triggers 19 are reset, the element is triggered. And 23 and the first trigger is reset to the call and the register 24. The call to the first controlled item stops, and remains in the first registration block 15 recording the state of objects in the fourth call, which is identical to the record in the third call. If, however, the fourth and third call silylation pulses are not identical, then the first controlled point is called for the fifth and sixth time, etc.

The counter 26 serves to count the repeated calls of the monitored item. If this number reaches a predetermined number, for example, five sufficient for a reliable judgment that the controlled item is in a faulty state, the counter is triggered. As a result of the triggering of the counter. The triggers of the call 8 and the objects 19 are reset, the reset to the initial position of the register 24 occurs, the counter 26 itself is reset to the initial zero state. Setting the counter 26 to the initial state also occurs from the call to the first element OR 13 after the call triggers 8 are reset from the AND element 23 of the reset. When the counter 26 is triggered, the malfunction of the called controlled item is recorded.

Thus, the invention makes it possible to increase the reliability of perceived information from controlled sites. This eliminates the occurrence of emergency situations and violation of the technological process and due to the issuance of control actions based on incorrect reception of information.
