摘要
设计了一种飞机发电机控制机器(GCU)的测试方案。该方案通过DSP TMS320F2812实现对GCU过压/欠压、过频/欠频、差分保护等17个项目的自动测试工作;DSP在对多个测试项目启控点控制的同时,也对电压、频率、时延等检测信号进行传输和处理;通过计算机对DSP发出测试控制信号和接受DSP上传的测试结果数据,保存测试报告。测试证明,该方案设计的测试系统满足GCU元件维修维护手册(CMM)的要求,是切实可行的。
This article describe an test method to GCU,17 test programs were tested automatically including GCU over voltage/under voltage,over frequency/ under frequency,difference protect and so on in the whole system.The DSP controlled the starting point of programs,at the same time transmitting and processing the test signal as voltage,frequency,time delay.Computer transmitted test control signal to the DSP and received test results by DSP,then saved the test report.The design of testing system to meet the requirements of GCU CMM.This test method is feasible
