Isolative gas - pressurized expansion device 隔绝式气体加压膨胀装置
2.
In hardware , we choose anti - disturbance photoelectric isolative sensor , take rc filter to resolve high - frequency for anti - disturbance . in software , we adopt arithmetic of recursion mean value to collective signal values to resolve low - frequency ac and pinnacle pulse disturbance 在硬件方面，选用抗干扰能力强的光电隔离电量传感器，并采取rc滤波抗干扰措施解决中高频干扰问题；在软件方面，对采集到的信号量采取递推平均值算法，解决低频交流和尖峰脉冲干扰问题。
