Description

one

The invention relates to the field of computer technology, telemechanics.

Known switchgear containing triggers with a counting input, zero outputs of which are connected to the input of the decoder, a pulse generator and a counter.

The capacity of the switchgear is determined by the number of pulses at the output of the decoder in one cycle of operation of the counter. If the trigger element of the counter fails, the number of pulses at the output of the decoder changes and depends on the bit number of the failed element.

The purpose of the invention is to increase the reliability of the device.

This is achieved by the fact that the distribution device contains pulsed frequency dividers, and the output of the pulse generator is connected directly to the counting input of the first trigger and, through the pulse frequency dividers, to the counting inputs of the other triggers.

The drawing shows a functional diagram of the device.

It contains a generator of 1 pulses, triggers 2, pulsed dividers 3 frequencies, which are based on the principle of pinning the energy of the input pulses and fixing the moment of arrival of the required number of pulses, which is determined by the number of the element cell, and the matrix diode decoder 4.

The output of the generator 1 is connected directly to the counting input of the first trigger 2 and through pulse dividers 3 frequencies to the counting inputs of the remaining triggers 2. The zero outputs of all the triggers 2 are connected to the input of the decoder 4, the outputs of which form the outputs of the switchgear.

The pulses from generator 1 are fed to the counting inputs of flip-flops 2: to the counting input of the first flip-flop directly, and to the outputs of the remaining (n-1) flip-flops through pulse frequency dividers 3, which divide the frequency of the pulses of the oscillator 1 in accordance with the established division factors the frequencies of each bit, where i (, 2, ..., n) is the sequence number of the bit of the trigger.

Subject invention

The switchgear contains its triggers with a counting input, the zero outputs of which are connected to the input of the decoder, and

The pulse generator is distinguished by the fact that, in order to increase reliability, it contains pulse frequency dividers, and the output of the pulse generator is connected directly to the counting input of the first trigger

and through pulse frequency dividers - with the counting inputs of the remaining triggers.
