通过激光IMU与遥测系统接口匹配中出现丢帧问题,与仿真设备接口匹配中出现输出异常数问题两个实际案例,利用示波器采集分析IMU输入输出的数据波形和时钟波形等,给出了一种利用示波器排故的便捷方法。该方法高效实用,对现场不会造成破坏,且不改变其它设备的技术状态,降低了研制成本,节省了排故时间。
In interface matching experiments,laser IMU and telemetry system lost frame data,laser IMU and simulation device output abnormal data,through two practical cases,using the oscilloscope collect and analyse the input and output data waveform and clock waveforms of IMU,an convenient method for troubleshooting by oscilloscope is presented.This method is effective and practical,has litter influence on troubleshooting site,and do not change the technical status of other equipments,reduce the development costs,save the troubleshooting time.
