The device relates to the field of telemechanics.

According to the main author. St. N ° 249443, a device for telecontrol and remote signaling in the code-pulse telemechanic systems is known, comprising a register, a synchronization unit, a protection unit, a pass counter, an address setter, a distributor, coincidence circuits, and memory blocks of the received information.

In known devices, it is difficult to set up elements of a control point located in a synchronization unit of a control point of elements that compensate for the delay of information signals transmitted from a control point to a control point and slow down the device, since the delay is compensated for closely located points by the maximum value existing for the most remote point.

In order to increase speed and simplify device setup, it contains a memory block of latency time and a switch, one input of which is connected to the corresponding output of the distributor, other inputs are connected respectively to outputs of the address setter, the output of the switch is connected to the second input of the time delay memory. block sync.

The drawing is a block diagram of the proposed device.

It contains the synchronization unit 1, the address setting unit 2, the 3 channel distributor, the register 4, the information receiving communication channel 5, the information transmission communication channel 6, the protection unit 7, 8i4-8 ,, matching circuits, 9 reruns counter, blocks message memories, output buses ,,, memory block 12 of latency value and switch 13.

The device works as follows.

The synchronization unit 1 periodically generates signals for switching the setting of 2 addresses and the distributor of 3 channels. The address code of the message group is entered by the address settingter into the register 4 and from it into the communication channel 6 to the telemechanics devices of the monitored items (not shown). The control point address code, along with the message code, is returned with a delay. The delay of incoming information from each controlled point is different and is determined by the remoteness of the controlled point from the control point, the type of channel-forming equipment used in devices and the structure of communication channels. This value is for each controlled item.

stored in block 12 of the memory of the timing of the timing and selected from it using the switch 13. The switch is controlled by the address setter of the monitored point and the distributor 3, the signal from which is fed to the input of the switch 13 at the time corresponding to the reception of the address. The delay value is inputted into the sihiroizacija unit, as a result of which the clock signals from the synchronization unit to the distributor 3 at the time stop, corresponding to the delay of signals arriving from the monitored point, are stopped.

Address and message signals are checked in security block 7.

If the signals have distortions, then the protection unit through the counter 9 reruns repeats the request for information, and if no signal searches occur, then the messages from the register 4 through the matching schemes 8, synchronously controlled by the distributor 3, are entered into the memory blocks 10 of the messages.

Simplification of the settings and increase in the reliability of the nodes correcting the lag of information transmitted from the controlled points is achieved by placing blocks 12 and 13 on the device of the control point, while increasing the speed of the device takes place due to accurate consideration of the greatness of the delays.
