摘　　要：为了能够精确控制艾灸点皮肤温度,提高艾灸效果,设计并实现了一个稳定高效的温度控制系统。该系统采用STM32F103单片机、TN901热电堆红外传感器和42BYGH604A步进电机,通过42BYGH604A步进电机驱动滚珠丝杠进而带动燃烧的艾条相对于艾灸点做前后运动,来调整艾灸点皮肤的温度。通过自整定模糊PID算法实现对艾灸点皮肤温度的稳定控制。实验结果表明,系统超调量为0.73℃;稳态温度保持在41±0.07℃以内。与常规的PID控制系统相比,基于自整定模糊PID算法的艾灸点皮肤温度控制系统具有更高的稳态精度。In order to accurately control the skin temperature at the moxibustion point and improve the moxibustion effect,a stable and efficient temperature control system was designed and implemented.The system uses STM32 F103 single-chip microcomputer,TN901 thermopile infrared sensor and 42 BYGH604 A stepper motor.The 42 BYGH604 A stepper motor drives the ball screw to drive the moxa stick to move forward and backward relative to the moxibustion point to adjust the skin temperature of the moxibustion point.Through self-tuning fuzzy PID algorithm to achieve stable control of skin temperature of moxibustion point.The experimental results show that the overshoot of the system is 0.73℃;the steady-state temperature is kept within 41±0.07℃.Compared with the conventional PID control system,the moxibustion point skin temperature control system based on the self-tuning fuzzy PID algorithm has higher steady-state accuracy.
