Cigarette production automatic counter based on single chip microcomputer

Abstract

The invention discloses a cigarette production automatic counter based on a single chip microcomputer, comprising a reflective infrared counting pulse-generating circuit used for sending infrared counting pulse to each cigarette on a cigarette conveyer belt, a signal amplification circuit used for receiving and amplifying the signals outputted by the reflective infrared counting pulse-generating circuit, a filter circuit used for receiving and filtering the signals outputted by the signal amplification circuit, an analog to digital conversion circuit used for converting the signals outputted by the filter circuit into digital signals, and a single chip microcomputer used for receiving and counting the digital signals outputted by the analog to digital conversion circuit, wherein the output terminal of the single chip microcomputer is in connection with a display used for displaying the quantity of cigarettes, and an alarm used for giving an alarm when the reflective infrared counting pulse-generating circuit is abnormal. The cigarette production automatic counter has the characteristics of simple structure, convenient use, accurate and reliable counting, and low production cost, and facilitates popularization.

Description

technical field [0001] The invention relates to a counter, in particular to an automatic counter for cigarette production based on a single-chip microcomputer. Background technique [0002] At present, domestic cigarette manufacturers generally use manual counting to measure the number of cigarettes. Manual counting has high labor intensity and low work efficiency. Working for a long time will easily cause visual fatigue, which makes it difficult to guarantee accuracy and hinders the improvement of system production capacity. Accurate counting of cigarettes has become a difficult problem that has plagued people for a long time. Based on this situation, a new type of automatic counting detection system is urgently needed to effectively improve labor productivity, change the traditional counting mode of "eye calculation and mental calculation" by workers, and liberate workers from heavy physical labor and harsh environments. The counting link of the cigarette production line...
