8z .:. The device operates as follows.

The initial operating mode of the device 5 is standby, i.e. remote control and telealarm signals are absent. On the control panel 1, the object light indicators are turned off.

The position of the control keys 16 is in standby mode. Now, when any of the monitored parameters is changed at the monitored item 17, one of their relays 61 is triggered - produces a recharge of the capacitor 69. The recharge pulse

5 amplified by the signal shaper 4, flips the trigger 27 of the operation mode to the tele-signaling resolution mode, i.e. a resolving logic 1 is supplied to the input of the AND-NOT element 55 of the signal transmitter 20 and the signal transmitter 20 begins to transmit pulse packets corresponding to the state of the monitored signaling objects to the communication line. This happens as follows.

5

The input of the AND-NOT element 55 of the transmitter 20. The signals are constantly receiving pulses. The same pulses from the output of the beat generator arrive at the input

0 counter-former 24 pauses, which forms after the transmission of eight information pulses a pause length of eight beats. In addition, from the output of the counter-shaper of 24 pauses, they receive 5 pulses to the inputs of the encoder 21 of the signals and the temporary selector 22. forming the number of pulses in the packet at a given time by monitoring with the help of elements NOT 58 and AND NOT 59 closing contacts 62 of relay 61 output elements

22 alarms for the status of monitored objects and tele-alarms.

If at the moment of operation of the AND-NOT 59 element, the state of the controlled object is not normal, i.e. the make contact 62 is closed, the logical O from the output of the AND-NOT 59 element throws the control trigger 19, the signal of the logical O from its output prohibits the operation of the transmitter 20 and a packet with the number of pulses equal to the state step of the signal encoder 21 at that moment time. In the normal state of the parameter being monitored at a given time, i.e. when the NO contact 62 of the relay 61 is opened when the AND-NOT 59 element is triggered, the control trigger 19 does not transfer and a packet of eight pulses arrives in the communication line from the signal transmitter 20;

The pulses from the communication line are transmitted to the console 1 through the key 16 to the driver 4. As a result, the light indicator is turned on, signaling that this monitored point has entered the telealarm mode. At the same time, the buzzer sounds.

In order to decrypt the telealarm signals, the controller sets this control key to the position. Decrypt signals. Now the signaling signals through the control key 16 are fed to the input of the signal receiver 11, and from the output to the pulse counter 13, which counts the number of pulses in the packet, and to the input of the pause selector 12. The pulses highlighted by the selector 12 serve to reset the counter 13 to the zero state after the last pulse of the burst, and also to record the final information in the triggers of the counter 13. The information recorded on the triggers of the counter 13 is decrypted by the decoder 14 and one of the block LEDs lights up 15 alarms. When the next burst of pulses arrives, the circuit works in a similar way and another LED of the signaling unit 15 lights up or, if this monitored parameter is normal and a burst of full eight pulses arrives, the line control LED lights up. Since the frequency of the clock pulses was chosen rather high, the illuminated LEDs of the signaling unit 15 light simultaneously and give a complete picture of the state of the monitored objects at this monitored item 17.

After receiving data on the state of monitored objects, the dispatcher sets the control key 16 to the telecontrol position. In this case, the communication line is disconnected from the input of the signal receiver 11, and connected to the output of the command transmitter 9. Then, the operator presses the Reset CP button 35 to bring the monitored points 17 to standby. Job

The remote control in the telecontrol mode is similar to the operation in the telealarm mode of the controlled item 17 and differs from the latter in that instead of a relay 61, a command generator 10 is used. The remote control 1 in the telecontrol mode issues the same in number of pulse packets to the line. In this case, the number of pulses in the packet is set by the shaper, 10 commands.

The remote control pulses arrive at the input of the command receiver 26 of the controlled point 17 and then the remote control signals are decrypted similarly to the operation of the remote control 1 in the telealarm mode. Moreover, if the Reset CP button was pressed on the control panel 1, then a logical O signal appears at the corresponding output of the command decoder 29, which is input

the trigger 27 of the mode and resets it to the standby mode.

The device also provides for the interrogation of KP on telecontrol.
