Résumé
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 min.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.
