Abstract:The most traditional detection of flight control computer of unmanned aerial vehicle (UAV)is manual operation, with cumbersome operation, large amount of data, vulnerable to human factors, resulting in low test efficiency, the results of subjective, lack of security.A one-button full-function detection scheme for flight control computer based on signal threshold automatic detection technology isproposed. A smart system of automatic detection is developed with 586-Driver board as the core. The interface board, power board, signal conditioning board and detection board are designed.Module function include the underlying drive, timing control, power control and current detection, functional testing, which realizes the sequential testing of the flight control computer without manual operation. The system test was carried out by using man-made fault test method. The test result shows:the system meets the requirement of detection,the efficiency of detection of UAV flight control computer is improved.
