Description

one

The invention relates to the field of digital computing and can be used to receive sporadically incoming two-step pulses into a computer.

The known device for interfacing a computational machine with two-position sensors contains drivers, registers, latches, buffer registers and delay lines.

The purpose of the invention is to increase the reliability of receiving sporadically received on-off pulses and simplify the circuit.

The proposed device contains coincidence circuits, the outputs of which are connected respectively to the fault inputs of each register-latch, some inputs are connected respectively to the outputs of the computer, and the others to the waste field of the computer. Such an embodiment of the device makes it possible in principle to exclude the loss of impulses or double reading and, in addition, simplifies the circuit.

Pa the drawing shows the functional scheme of the described device.

It has bus / input signals that are connected to the inputs of drivers 2. Their outputs are connected to the inputs of the latch registers, to the other inputs of which.- ..

The outputs of the matching circuit 4 are connected respectively. computer machine. The output tires 9 of the computing machine are connected respectively to the inputs of the coincidence circuits 4, to the other inputs of which the reset bus 10 is connected from the computing machine.

The device works as follows.

Sporadic on-off pulses are received from the input buses / to the inputs of the formers 2, which are differentiated, and the pulses appearing along the leading edge, from the output of the formers 2 arrive at the inputs of the latch registers 3 unit increments where they are stored. The output potentials of the register-fixers arrive at the inputs of the buffer registers 5, to the other inputs of which bus 6 is driven

communication with the computer. The pulses entering the computer are remembered there and fed to. the form of the potentials to the corresponding output buses 9. From these regions, the pulses arrive at the corresponding inputs of the coincidence circuits 4, and simultaneously a reset signal is sent from the computer 10 to the other inputs of the coincidence circuits 4. At the outputs of the coincidences 4 impulses that reset the corresponding register-latches 3 unit increments. Thus, only those fixation registers 3 unit increments are performed, in which at the moment of arrival of the signal the pulses were stored, which followed through the corresponding buffer registers 5 and recorded in the computer 7.

Subject of invention

A pairing device, a computer with dual-pin and pulse sensors, which contains drivers that are connected through single-increment latching registers and buffer registers to the computer, characterized in that, in order to increase the reliability and simplify the device, it contains matching circuits whose inputs connected to the computer, and the outputs - to the registers of individual applications.
