届毕业生毕业设计说明书题目：基于单片机的称重控制系统设计院系名称: 专业班级：学生姓名:学号：指导老师:老师职称:摘要由于称重器具在商业贸易中的重要作用，称重技术的进展一直都受到人们的关注.本文设计实现了一种新型的多功能电子称重系统,该系统采纳了最为常见的 C51 系列单片机STC89C52 作为主控芯片,系统可以准确称量待测物的质量,使用者设置好单价后，系统还能自动地计算总价并可以把测量结果直观地显示在液晶屏幕上,同时本系统还具有超量程自动报警功能。另外本系统还扩展了电子万年历和电子温度计的功能，使得系统更加有用。本文论述了课题提出的背景，系统方案确定的依据以及系统具体硬件电路的设计方案和软件编程的基本思路,最后针对系统的测试结果进行了分析。关键词:电子称重系统；单片机；称重传感器；A/D 转换；时间和温度;人机交互TitleDesign of weighing control System Based On MCU ABSTRACTDue to the important role of weighing apparatus in the trade ， development of weighing technology has been paid close attention to by people 。 This paper presents a new type of multifunctional electronic weighing system 。This design is based on the most common C51 series microcontroller STC89C52 as a control core, it realized the basic functions of electronic scales. This design can acquisition quality accurately， display test data intuitively， set the price for diffident things and automatic alarm when it is over range。 At the same time, the system also extends the function of electronic calendar andthethermometer, making the system more intelligent and practical 。 This paper discusses the background of the subject ， how the system scheme is determined，design of the hardware circuit system and software programming. At the end of the paper, the system test results were analyzed.Key WordsElectronic scale； single chip microcomputer； sensor； A/D conversion； human—computer interaction; time and temperature目录摘要 IABSTRACTII第 1 章前言 11.1 ...
