Description

one

The invention relates to the field of automation and computer technology and is intended for number-pulse coding of information.

A known device for generating bursts of pulses, comprising a pulse generator, a trigger, a comparison circuit, a pulse counter, a trip-relay, the output of the pulse generator connected to the output of the device and one of the outputs of the pulse counter, the discharge outputs of which are connected to the inputs of the comparison circuit , the output of the circuit is connected to the input of a kilp-relay, has a complex structure and low speed.

The purpose of the invention is to increase the speed and boost the generator.

To do this, an additional pulse counter is entered into it, the bit outputs of which are connected to the inputs of the comparison circuit, one of the inputs of the additional pulse counter is connected to the trigger output and one of the pulse generator inputs, the second input of the second pulse counter is connected to the second input of the main pulse counter, the third input of which is connected to one of the trigger inputs, the second trigger input is connected to the device input, to the second input of an additional pulse counter and to one of the output Kipp-rel e, the second output of which is connected to one of the inputs of the pulse generator.

The drawing shows a block diagram of the proposed device.

It contains the main counter / pulses, pulse counter 2, trigger 3, pulse generator 4, bitwise comparison circuit 5, Kip-relay 6, device input 7, device output 8.

Device Works as follows. In the initial state, the counters / and 2 are in the zero position, the trigger 2 is in the state in which it blocks the generator of 4 pulses.

When a start-up impulse arrives at the input of the device, counter 2 is written down and trigger 3 is tilted, removing the lock from the generator of 4 pulses, which goes into (self-oscillation mode).

The first pulse from the output of the generator 4 pulses is fed to the output of the device and the input of the counter 1, in which the unit is recorded. The comparison circuit 5 triggers a Kipp relay 6, which for the time of operation

blocks the generator 4 pulses, and the front

the front of the impulses kipp-relay 6 sets

the counter 1 to the zero position and writes

unit in counter 2.

Thus, the first packet is formed.

pulses consisting of a single pulse.

After the end of the blocking pulse, the pulse generator 4 begins to generate a second pulse pulse. Since two units are recorded in counter 2, the comparison circuit 5 will work when a / pulse arrives at the counter. After that, the operation of the device will proceed as described above.
