Abstract

The device relates to communication technology. The purpose of the invention is to reduce energy consumption. With the signals of all sources 1, 2, 3, the code 111 is recorded in the register 13 for storing the results of the control of the sources, an output signal appears at the outputs of the gates 10-12 connected to the register 13. A trigger 14 is energized on the 1st pulse from the switching pulse distributor 9, and an enable signal also appears at the gate inputs connected to the trigger output 14. The next impulse from the switching pulse distributor passes alternately through the gates 10, 11, 12 and goes to the interrogation keys 4-6, a sequential polling of the sources of signals 1-3 occurs.

The device relates to a communication technique and is an improvement of the invention according to the author. No. 491218.

The aim of the invention is to reduce energy costs. .

The drawing shows a structural electrical circuit of the proposed device.

A device for transmitting discrete information contains sources 1, 2 and 3 signals, interrogation keys 4, 5 and 6, inverter 7, element 8, distributor 9 of source switching pulses, valves 10, 11 and 12, register 13 storing the results of control sources, trigger 14, element OR 15, accumulator 16, additional trigger 17, element AND 18, additional element OR 19, communication line 20, majority decoding unit 21.

A device for transmitting discrete information works as follows.

With the correct signals of all sources 1, 2 and 3, the code 111 is written to the register 13 for storing the results of the source control, a enable signal appears at the outputs of the gates 10-12 connected to the register 13. A trigger 14 is driven by the first pulse from the distributor 9 of the source switching pulses, and an enable signal also appears at the gate inputs connected to the trigger output 14. The next impulse from the distributor 9 impulses switching sources passes through the open valve 10, the next impulse through the valve 11, the third through the valve 12. These pulses arrive at the interrogation keys 4-6, the signal sources 1-3 are sequentially polled and transmitted

the signals arrive at the input of the inverter 7 and the first input element And 8.

The first pulse from the output of the element OR 15 sets an additional trigger 17 to position 1 and the input of line 20 of the communication through the element AND 8, the additional element OR 19 receives the direct value of the signal source 1-3.

0 with the arrival of the second pulse to the counting input of an additional trigger. 17 he set. to the position about and to the input of the link 20 through the inverter 7, the element AND 18 and the additional element OR 19 enters the inverse value of the signal source 1-3. In the third transmission session, an additional trigger 17 is set by a counting pulse to position 1 and the direct value of the signal source 1-3 is fed to the input of the communication line.

Thus, when transmitting code 1, the transmitter's power margin must be such as to ensure not 3, but 2 active premises, i.e. Code 101, not 111.
