On potential triggers 10, the binary code of the address selected for the transfer immediately appears through the switch / 1uchrc 25 to block 7. After the parallel code of the address is converted into a sequence and the OGO is output to the communication line, the control signal is written by the front signal triggering analog-to-digital converter 8 and with

using decoder 6 opening key 3 of the selected channel

The duration of the control signal of block / must be no less than the conversion time of the analog of the digital conversion (8). The trailing edge of the control signal of block 7 resets the adaptive temporal discretization 2 selected, the south channel and through the trigger 16 the passage of the generator 17 pulses through element 18 is allowed to counter 15 At the output of the digital-to-analog converter 14, the voltage is reduced by steps, starting from the highest value. This variable is set to the additional inputs of the adaptive time samples. rop 2 The signals 1 from the outputs of the triggered samples are sent to the element OR 19 whose output signal through the trigger 16 and the element 18 prevents further input of the pulses of the generator 17

However, in the course of the device operation, such a screening / acti when the inactive or faulty channel is not polled and recorded will not result in unacceptable errors in this channel and will make it difficult for ucnoTbJOBdHHe information from this channel to eliminate this phenomenon. control from the Gy-trench 20 - 25 The control is carried out sequentially, starting from any channel depending on the initial state of the counter 21 The code from the output of the counter 21 is compared in block 20 of the codes with the address code, I enter input unit 7 from unit 9 memory device at the time of the control signal from unit 7 If in the maximum possible time determined by the waiting multivibrator 22, the address appears at the output of unit 9, the same as the code at the output of the counter 21 , then a signal appears on the output of block 20, switching counter 21 to the next control channel. Simultaneously resetting the standby multivibrator 22 occurs. Singing the same time determined by the standby multivibrator 22 is not enough to reveal the code of the controlled channel on the address outputs of the block 9 memory, the waiting multivibrator 22 is triggered. The signal from the output of the multivibrator 22 using AND 23 and the trigger 24 sets the switch 25 to such a position that the code from the counter 21 corresponding to a non-polled channel arrives at the input of the read block 7 Next, the code enters the decoder 6, which with the help of keys 3 connects

to the analog-to-digital converter 8, the signal from the selected sensor. Thus, the communication channel receives information about the channel whose address code is in the counter 21. After transmitting the information to the communication channel, the counter 21 switches to the next position, the waiting multivibrator 22 is reset and through the element 23 and the trigger 24, the switch 25 is set to the starting position corresponding to the normal mode of operation. The channel search begins and the cycle of operation is repeated. The control signal from the readout block 7 is the synchronization signal for the element 23 and the trigger 24

The device allows the transmission of information from sources with sharply differing activities, and the information from low-active channels is recorded at regular intervals determined by the usability of the information.
