Chinese medicine therapy fumigation is a traditional medicine treatment to implants the medicinal preparation partially. The traditional method is the steam which uses a medicine while using boiling traditional and herbal drugs a medicine smoked steam the body for some time to achieves the treatment goal. To ensure that sufficient time to appropriate and more constant temperature to heat and liquid active ingredient to the lesion full of infiltration, can not achieve the best results. To achieve the rapid temperature control and accuracy, improving the quality of the medicine is a very important practical significance. According to the company, we Designed by a smart control of the microcontroller Chinese medicine treatment for fumigation. The system to AT89C52 SCM as the core, users can set up under the temperature and time are adjusted automatically constant temperature steamThe temperature control issues against the characteristics and achieve precise control of temperature, Based on the design of a PID temperature control system. Design elements include hardware and software in two parts. Hardware circuit to AT89S52 MCU for microprocessors, for the detailed design of the microcontroller to provide electricity supply circuit, Temperature signal sampling circuit, keyboard and display circuits, such as heating control circuit four circuit module. Software major part of the PID algorithm is a mathematical modeling and programming. PID tuning parameters are used to a fixed parameter. The circuit design of the keyboard input from the set temperature signal to the microcontroller, Temperature Signal Acquisition Circuit collect temperature signal to the microcontroller, According to SCM input and feedback signal, the error for PID, the output control signals to the heating control circuit, Heating and achieve stop. Show circuit scene of the real-time monitoring of temperature.The system is simple, and hardware, but also the real-time temperature, with the particularity of the control process, The design of a PID algorithm based on the temperature control to achieve the temperature control system, the main aim is to achieve the production process for the temperature control speed, high accuracy.
