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。
A test program of Aircraft Generator Control Machine (GCU) was designed. The program through the DSP TMS320F2812 GCU overvoltage / undervoltage, over / under frequency, differential protection and other 17 projects of automatic test work; DSP in a number of test items control point control at the same time, but also on the voltage and frequency , Delay and other detection signals for transmission and processing; DSP issued by the computer test control signals and receive DSP test results upload data, save the test report. Tests show that the test system designed to meet the GCU component maintenance manual (CMM) requirements, it is feasible.
