Abstract

The invention relates to a computing and information technology and is intended for automatic counting of products. The device provides high accuracy of counting. The device contains sensor 1, elements AND 2, element OR 3, divider 4 frequencies, counters 5, 6, delay element 7 and decoder 8. The device is based on the fact that the conversion factor of counter 6 is switched depending on the amount of accumulated information. The change of the division factor is carried out by switching the outputs of the divider 4 according to the control signals of the counter 5 through the decoder 8. 1 sludge.

Description

The invention relates to a computing information technique and is intended for automatic counting of products.

The purpose of the invention is to increase the accuracy of the counting, due to the fact that the conversion factor is determined by the volume of the counting device.

The drawing shows a block diagram of the device.

The device contains a sensor 1, the first element And 2, the element OR 3, the divider 4 frequency, the second 5 and the first 6 counters, the delay element 7, the decoder 8 and the second elements .j. Divisor 4 consists of a counter, and the first counter 6 consists of bits 11 and the last bit 12.

The device works as follows.

In the initial state, the counters 5 and 6 and the divider A are set to O. When pulses are output at the output of sensor 1, these pulses come through the first element I 2 to the counting input of counter 6. If after some time of operation the entire counter 6 is filled and overflow , the overflow pulse translates counter 5 into a single state, allowing the pulses to pass from the first output of the divider 4. At the same time, the overflow pulse

sets the last digit of the counter 6 to 1. Similarly, the transition to other ranges of conversion by the device occurs.

Thus, the device selects the appropriate conversion range, depending on the volume of the counter at the current time.
