Designed a PID algorithm-based Chinese medicine treatments thermostatic control system on the working principle of the system hardware circuit and software design, discusses the principle of digital PID controller and its constant temperature control system. Controller by the microcontroller, temperature acquisition module, temperature control module, display modules and other modules can be combined with on-site temperature and the target temperature set by the user, using PID algorithms and PWM technology, the temperature is gradually stable set by the user target. The application button is set target temperature, heating time, the LCD display real-time, temperature and heating countdown display is being heated, timer countdown, alarm status of the three green, yellow, red lantern. The controller can meet the the physiotherapy temperature control equipment needs and control accuracy, more convenient, intelligent, with the majority of the market demand.
