The Thermal Radiation Rotating Magnetic Therapy Device Based On C8051F020

The main application of this therapeutic instrument is subject to obesity, snoring patients, the main mechanism is infrared therapy and magnetic therapy.First of all, the paper summarized the background of the research. Then it respectively introduced the important role of the far-infrared therapy and rotating magnetic therapy. At last, the important means of researching the comprehensiv-e treatment result of the two therapy mentioned before.The paper discusses design ideas of combination of the rotating magnetic therapy module and far-infrared therapy module at first.Then, it recommend all the module of the design system in detail and in-depth. The design of this system is around the low-power and high-speed 8-bit MCU C8051F020,which is belong to enhanced 51 MCU. The design combined with gyromagnetic and far infrared heating module, which contain hardware circuit and software system in these two aspects. Then the paper discuss more about hardware circuit and software system of gyromagnetic module and far infrared heating module for the specific requirements. The system selected amplifier, Hall element, Temperature Sensor and other components for analog and digital hardware design and debugging. It through the design of the duty cycle of the PWM circuit controlled to achieve a rotating magnetic adjustable speed and through the MOS transistors in parallel and the use of relays to achieve a far-infrared heating temperature controlled. The design contains the module of the rotating magnetic speed detection and control. It also contain the far infrared temperature detection and control module, key input module and LCD module.System software compile and debug code by KEIL and IDE.The software through buttons, LCD program designed to achieve the parameter setting and the real-time display and other interactive features.The treatment time and the parameters can be set.The treatment and other important data can be displayed in real time function.The research is tested by the comprehensive result of hardware and software functions therapy. The final results show that the therapy device can achieve the design requirements.At last the paper summarizes the system functions and results of debugging.
