摘要
许多生产现场均采用生产流水线设备来生产各种产品，并且随时对产品的产量进行统计。本课题就是针对这一生产时间需求，以单片机为核心器件构成一个检测显示系统，来实现生产流水线上产品产量的统计和显示。
在实际应用中，为统计各生产班组的班产量，可在生产流水线的终端，安装一个光电检测装置，当每一产品经过该装置时，会产生一个光电脉冲，交到单片机进行计数处理，然后由LED数码管进行计数显示。每生产一台产品，显示数加1，直到一个班生产完毕。这就实现了一个班班产量的累计显示。
本文首先介绍了单片机的相关概念以及其原理，然后介绍了实际系统的设计，在次基础了用89C52和7段数码管设计了生产流水线上产品产量显示系统。
实现了以下功能：
（1）采用单片机为核心器件，构成一个生产流水线产品产量统计显示系统。
（2）用四位7段数码管动态显示班产的产品件数（不超过10000件）。
（3）设置一个记数开关，当开始生产的时候开关置高电平，系统开始统计并且动态显示班产量，当开关置低电平时停止记数，显示值清零，班产量存入指定存储单元备用。

Abstract
Many production site equipment production lines are used to produce a variety of products, and the output of the product at any time statistics. The issue is a response to this production needs time to a microcontroller as the core device of a display system to achieve the production line on the production of statistics and display.
In practical application, the production statistics for the class production team, production lines in the terminal, the installation of a photo detector device, when each product through the device, it will generate a photoelectric pulse, delivered a Microcontroller Count and then by a count of LED digital display. Each production a product that increases the number 1, until the end of a class production. This classes to achieve a total output of the show.    In this paper, the concept of SCM and its related principles, and then on the actual system design, the basis used in the 8031 and 7 of the digital design of the production line, output display system. Achieved the following functions: (1) using SCM as the core device, constitute a production line output statistics system. (2) in paragraph 7 with four digital dynamic display of the middle classes of products (not more than 10,000). (3) the provision of a few switches in mind, when production started when the home HIGH switch, the system began keeping statistics on production and dynamic display of class, when the switch at the low end home and several that cleared value, output in designated storage classes reserve unit.
