Description

one

The invention can be used in automotive, telemechanics, and digital computing. Signal transmission devices are known from several asynx: equipmental sources (sensors), which allow to extract useful information while simultaneously receiving other signals using asynchronous decoding.

The main disadvantage of such devices is: THEIR COMPLEXITY.

The purpose of the Invention is to simplify the device. "Save the information transmission reliability."

The goal is achieved by the fact that the output of each sensor f-ro of the sensor is connected to the input of the delay lily through the NOT circuit and to the first input of the AND circuits, the second input of which is connected to the output of the multiple input AND circuit, and the output to the single trigger input, the output of which is connected to the second inputs of all the circuits “NOT except i-and.

The block diagram of the device lrivadena on the drawing.

For the allocation of information, a register | p consisting of the latency delay / and the multi-input < 2 > circuit is used.

Upon receipt of a 3 or 4 input from the corresponding sensor, consisting, for example, of three pulse sequences, it passes through the circuit "NOT 5 or 6 and enters the register.

The information allocated by the register in the form of a single impulse is sent to the schemes “And 7, 8;

The other input of one of them simultaneously receives a pulse from the corresponding input. The "And in coincidence" scheme at both inputs triggers and triggers the corresponding trigger 9 or 10. The trigger triggers a voltage to the control input of circuit 6 or 5 to disconnect the other input from the register. The trigger trigger transition occurs after a certain period of time after the end of the required information arrives at the input, due to which a connection to the second input register occurs.

PRED ME of the invention

A device for transmitting information containing sensors, a delay line, the outputs of which are connected to the multi-input cxeiMe AND, triggers and logic circuits AND and NOT, characterized in that, in order to simplify the device, 1 OUTPUT of each g-th sensor is connected to the line input delays through the circuit "NOT and with the first VO of the circuits" And, the second input of which is connected to the output.

The main circuit 1 "And, and the output - with a single input to the second inputs of all circuits" NOT ,.

trigger house, a single exit kotrroto with-except for gth.
