摘 要
随着自动化、数字化和机电一体化的进步,智能化的仪器得到了广泛的使用,智能化的技术能提高生产管理的水平,采取红外传感器制作的电子计数器可以实现自动化的控制。再加上单片机技术的提升,让实现功能电路变得简单,给人们的生活带来了方便。
以往的机械或电子计数器,电路布局复杂,而且需要的元器件数量比较多。处理系统的稳定性相对较低外,当系统出现故障时,维修的成本也很高,功能不容易修改,因而得不到普及。而以单片机为控制器的红外计数装置有很多优势,单片机的实时、准确性高、不易被干扰、电路设计简单。本文设计的是一个4位红外计数器,用途非常普遍,如实时工控、导航、电器等。对于机电一体化,单片机能实现高度的自动化、集中化。

Abstract
With the progress of automation, digital and mechanical and electrical integration, intelligent instrument has been widely used, intelligent technology can improve the level of production management, take the infrared sensor and electronic counter can realize automation control. Combined with single-chip microcomputer technology, to realize function circuit becomes simple, brought convenience to peoples life.
Mechanical or electronic counter, circuit layout is complex, the number of components and need more. The stability of the processing system is relatively low, when the system failure, maintenance cost is high, the function is not easy to modify, and therefore is not popular. And with the single chip processor as the controller of the infrared counting device has many advantages, microcontroller, real-time, high accuracy, susceptible to interference, simple circuit design. Is designed in this paper a four infrared counter, use is widespread, according to the facts in industrial control, navigation, electrical appliances, etc. For mechanical and electrical integration, SCM can achieve high degree of automation and centralized.
