摘　　要：介绍了一种基于单片机应用于足浴器的自动控温系统的实现原理及方法。该控温系统利用51系列单片机,由开关电源高效稳定供电,通过外围引脚中断、定时器、PID算法、DS18B20温度传感器,实现了温度实时显示,按键调节设定温度功能,解决了加热及冷却过程中热过冲与过冷问题。其成本低、控温精度高、温度可调、运行稳定可靠。This paper introduces the theory and methods of realizing an automatic temperature control system in a foot massage machine based on MCU implementations. This system achieves the functions of real-time temperature display and target temperature adjustment by buttons and solves the problem of over heating or cooling of the wire dur- ing the heating or cooling process with the perfect performance of traditional 51 series MCU, highly efficient and sta- ble power supply, external pin interrupt, timers, PID algorithm and DS18B20 temperature sensor. It has the ad- vantages of low cost, high precision of temperature control, adjustable target temperature and stable and reliable op- erating process.
