摘　　要：针对目前现有电针治疗仪的不足,提出基于ARM微处理器和u C/OS-II实时操作系统的电疗仪设计方案。该方案利用ARM产出PWM波,然后通过低通滤波、电压放大以及电压电流转换,最终以输出恒定电流作用于人体,有效地克服了人体穴位电刺激适应现象,且参数调节精准,操作界面友好,样机运行稳定。In view of the current deficiency of electro-acupuncture instrument, a new design was work out based on ARM and uC/ OS-II. First of all, PWM waveform was generated by the ARM microprocessor. Secondly, the PWM waves was processed through the low pass filter, a voltage amplifier and voltage to current conversion circuit. Lastly ,a constant current was output to the human body. The prototype designed in this paper is not only friendly,stable and adjustabe easierly, but also can overcome the electric stimulation adaptation of the human body acupoint effectively.
