Description

one

The device relates to the field of counting signals from several sources and can be used in multichannel communication systems, in nuclear physics, in statistical analysis systems, in multiline queuing systems, in surveys of passenger traffic of large transport facilities.

A device for recording pulses is known, comprising sensors connected to OR circuits connected to counters.

The disadvantage of it is the lack of accuracy of the device.

In order to improve the accuracy of work, a registering unit and a series-connected adder, a divider, a delay element and an inverter, whose input is connected to the recording unit and the output to another input of each OR circuit, are introduced into the device, and the adder inputs are connected to the corresponding pulse sensors.

The drawing shows a block diagram of the proposed device, comprising pulse sensors 1-3 from the first to the i-th channel, counters 4-6 from the first to the th channel, adder 7, divider 8, recording unit 9, delay element 10, inverter 11 and schemes “OR 12 to two inputs.

Pulse sensors 1, 2, 3 are connected to the inputs of the circuits OR 12 and with the voltage of the accumulator 7. The outputs of the circuits OR are connected to the inputs of counters 4, 5, 6. The input of the circuits OR will also receive a signal from the output of the inverter P. Output The adder 7 is connected to the input of the splitter 8, the output of which is connected to the input of the element of the delay 10, and its output to the input of the registering unit 9 and to the input of the inverter 11.

In the initial device layout, the counters 4, 5, 6, the divider 8, and the delay element 10 are in the zero state. The incoming signals are recorded in blocks 4, 5, 6, 8. At the output of the divider 8, when it arrives at its input, the number of signals of the same sign is greater than the number of received signals of the opposite sign by the amount

equal to the number of channels, a signal appears, the sign of which coincides with the sign of most of the prior signals of their signals. The signals through the adder 7 are fed to the input of the divider 8 and through the scheme "OR 12 - to the input of the counters

4, 5, 6. The signal from the output of the divider 8 is delayed by the delay element 10 to eliminate races in the counters 4, 5, 6 and enters the recording unit 9p through the inverter 11 and the OR 12-into counters 4, 5, 6.
