基于586-Driver的无人机飞控计算机智能检测系统研制

摘要

传统无人机飞控计算机检测以人工操作为主,操作繁琐、数据量大、易受人为因素影响,导致测试效率低、结果主观性强、安全性不足;提出基于信号门限自动检测技术的飞控计算机一键式全功能检测方案;以586-Driver板卡为核心,设计了接口板、电源板、信号调理板和检测板,研制了智能检测系统;模块功能包括底层驱动、时序控制、上电控制与电流检测、功能检测等模块,实现了在全程无人干预情况下对飞控计算机按预设时序逻辑的自动测试;采用人为注入故障测试方式进行了系统测试,结果表明:该系统满足某型飞控计算机的检测需求,提高了飞控计算机检测效率,具有实际工程应用价值.%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.
