摘　　要：探究了人体电阻对电刺激安全性的影响,设计了一种电刺激理疗设备恒功率输出与保护系统.通过负载端采样电阻的反馈值计算出设备的实际输出功率,与设定的阈值进行比较,利用增量式PID控制技术输出比较误差,间接调节电刺激的输出电压,对现有功率进行校正,同时改变流过人体的电流,达到提高设备治疗效果、保护患者的目的.In this paper,the effect of human body resistance on the safety of electrical stimulation is explored,and a constant power output and protection system for electrical stimulation therapy equipment is designed.The actual output power of the device through the feedback value of the sampling resistor at the load end is calculated,it is compared with the set threshold,the incremental PID control technology is used to output the comparison error,indirectly the output voltage of the electrical stimulus is adjusted,and the existing power is corrected.At the same time,the current flowing through the human body is changed to achieve the purpose of improving the therapeutic effect of the device and protecting the patient.
