Intelligent moxibustion instrument based on C8051F020

目的依据中医艾灸原理研究一种基于微处理器（MCU）的智能艾灸仪。方法采用混合信号系统级MCU芯片C8051F020，设计一种能发热、发光并将检测到的温度上传至主控单片机的4种艾灸头，以及能单独设定温度、灸疗时问的16路输出口。结果艾灸头温度控制范围为30～60℃，误差≤±3℃；定时时间范围为10～90min，满量程定时误差≤±1min；灸头红外全法向发射率平均为0．89。结论测试结果满足艾灸仪的参数要求，且操作简便，安全可靠。

Objective To develop an intelligent moxibustion instrument based on MCU, on the basis of moxibustion principles of traditional Chinese medicine. Methods A mixed-signal system-on-chip MCU C8051F020 was used to design four kinds of moxibustion heads to heat, light, and to upload detected temperature to the host microcontroller. Sixteen output ports were designed of which temperature and moxibustion time can be individually set. Results The temperature range of moxibustion head was 30-60℃, with error ≤±3 ℃. The timing range was 10- 90 min, and full-scale timing error was ≤±1 rain. The average infrared all normal emission rate of moxibustion head was 0.89. Conclusions The test parameters meet the requirements for moxibustion instrument, and the instrument is safe, reliable and simple to operate.
