水温控制系统设计与总结报告 水温控制系统设与总结报告 摘 要 本设计是制作一水温测试系统，采用单片机89C51完成对水温的控制。采用DS1820温度传感器对水温进行测量 ，系统能够实现在一定范围内人工设定、自动控制温度等性能。同时还扩展具有报警提示、时间提示，加热状态提示，过温保护等功能，增强了系统的实用性。经实验测试表明，该系统各项功能几乎已经达到题目的要求。 关键词：测温控制，报警，电路保护 Take off Want This design is to manufacture one water temperature test system, adopting a machine 89 C51s to complete the control toward the water temperature.Adopt the temperature of DS1820 spreads the feeling machine to carry on the diagraph to the water temperature, the system can carry out to set in the certain scope wife work, the automatic control temperature etc. function.Still expand to have to report to the police to hint at the same time, time hint, heating the appearance to hint, over protection etc. function, strengthenned the function of the system.Was express by the experiment test, various functions of that system almost have already attained the request of the topic. Keyword:Measure control, report to the police, the electric circuit protection 目 录 1. 系统设计------------------------------------------------------------------------------ 1.1 设计任务及要求-------------------------------------------------------------------- 1.2 总体方案设计、比较------------------------------------------------------------- 1.2.1 控制方案的确定----------------------------------------------------------------- 1.2.2 键盘输入与显示模块----------------------------------------------------------- 1.2.3 测温模块-------------------------------------------------------------------------- 1.2.4 报警与状态显示模块----------------------------------------------------------- 1.2.5 电源模块-------------------------------------------------------------------------- 2.单元电路的设计------------------------------------------------------------------------ 2.1 控制模块的设计-------------------------------------------------------------------- 2.2 键盘与显示最小系统的设计----------------------------------------------------- 2.3 测温电路的设计-------------------------------------------------------------------- 2.4 报警与状态指示模块的设计---
