SU423176A1 - DEVICE FOR SHIFT INFORMATION - Google Patents

Description

one

The invention relates to the field of discrete technology and can be used in devices and systems for the synchronous transfer of information about moving products, for example, in the systems of sounding and sorting of sheets (pipes), built on the principle of modeling the movement of transport mechanisms.

A device is known that contains a clock pulse generator and, in each m, bit, the AND pattern and a pulse counter, the input of which is connected to the AND bit discharge circuit output, and the AND gate circuit input is connected to the clock pulse generator output.

However, such a device cannot perform synchronous information transfer. For this purpose, a device constructed on the basis of a shift register and containing a large number of elements is used.

The purpose of the invention is to significantly reduce the number of elements in a device for shifting information while maintaining the accuracy of synchronous information transfer.

This goal is achieved by the fact that the proposed device contains in each bit an additional memory cell, the first input of which is connected to the output of the previous-generation pulse counter, and the second to the output of the counter of the same-named impulse;

the output of each memory cell is connected to the input of the circuit “And of the same name of the same name.

The drawing shows a block diagram of two bits of the device.

The device contains a memory cell 1, the output of which is connected to the input of the circuit "AND 2 of the same discharge, the second input connected to the output of the clock pulse 3. The output of the circuit" AND 2 is connected to the input of the pulse counter 4 of the same discharge, the output of which is connected with the input of the memory cell 1 of the same name and the memory cell 5 of the subsequent bits (6 - the “And, and 7 is the same pulse counter

bit)

In the initial state, the output signal of memory cell 1 prohibits the passage of clock pulses from generator 3 through the circuit "AND 2 to the input of pulse counter 4, all bits of which are in the state" O.

When writing information to the memory cell 1 of the first bit, the “AND 2” circuit opens, and the pulse counter 4 starts counting clock pulses. Having counted a specified number of pulses, counter 4 generates a signal that goes to the input of memory cell 1, changes its state and, thus, prohibits the passage of clock pulses through an AND 2 circuit. At the same time, the output signal of counter 4 is stored by memory cell 5 the subsequent

bit, the signal from which permits the passage of clock pulses from generator 3 to the input of pulse counter 7 of the last digit, which, having counted a predetermined number of pulses, generates a signal to reset memory cell 5 of the same name and overwrite the information in the memory cell bit
