一种用于电动轮椅车抗扰度试验轮速监测的装置

A Device for Wheel Speed Monitoring in Immunity Test of Electrically Powered Wheelchairs

电动轮椅车的电磁兼容试验需执行标准GB/T 18029.21-2012《轮椅车第21部分:电动轮椅车、电动代步车和电池充电器的电磁兼容性要求和测试方法》,该标准要求抗扰度试验中需监测电动轮椅车的轮速变化。该文介绍了一种用于电动轮椅车抗扰度试验轮速监测的装置,该装置可精确计算并显示轮速变化数据,以方便医疗设备设计人员和测试工程师对试验结果进行判定。

Since the electromagnetic compatibility test of electrically powered wheelchairs needs to implement the standard of GB/T 18029.21-2012 Wheelchairs-Part 21:Requirements and test methods for electromagnetic compatibility of electrically powered wheelchairs and scooters,and battery chargers,which requires that the wheel speed change of electrically powered wheelchairs needs to be monitored in the immunity test,this paper introduced a device for wheel speed monitoring in immunity test of electrically powered wheelchairs,which can accurately calculate and display the wheel speed change data,so as to provide convenience for medical equipment designers and test engineers to judge the test results.
