基于单片机的水温控制系统设计辉摘要：本水温控制系统以 MCS-51 单片机为中心控制器件，主要由温度传感模块，A/D 转换放大模块，单片机编程模块，显示模块，控制模块等部分组成。温度信号由温度传感器 AD590 采集，经过放大转化为电压信号进行编码，测温分辨率 0.1℃。水温实时控制由继电器电热丝和风扇进行升温柔降温。显示部分由“人机交互界面”的 12864 液晶显示，增加可读性。该系统具备较高的测量精度，能较好的完成设计要求。关键字：MCS-51 单片机 AD590 水温控制Abstract: The temperature control system ，which is regarded as the central control device of MCS-51 microcontroller, is constructed by the temperature sensing module, A/D converter amplifier module, control module, microcontroller programming module, display module and other components. Temperature signal is collected byte AD590 temperature sensor which is amplified into a voltage signal is encoded, temperature resolution is 0.1 ℃. Real-time control temperature can be heated by heating wire and electric fan. Display part is quoted by “man-machine interface” of 12864 LCD to increase the readability. The system features is of high accuracy, and it can have better complete of the design requirements.
