The invention specifically relates to an airplane pre-flight self-detection method, which comprises the following steps that: LRU equipment is divided into A-type equipment, B-type equipment and C-type equipment, and the A-type equipment directly reads other completed self-detection results as PBIT detection results; the B-type equipment needs to be driven by a VMC to detect, configure a zero position, apply excitation or cancel excitation; the C-type equipment is autonomous detection equipment, the VMC sends a detection instruction, detection is automatically executed, and the VMC reads a detection result in a delayed mode; performing parallel detection on all the C-type devices, and simultaneously performing serial detection on the A-type devices and the B-type devices; the detection of each LRU device is configured to be realized in one function unit; modeling is carried out on the detection state of each piece of LRU equipment; the PBIT main function schedules and executes once every 12.5 ms, the PBIT main function schedules all function units detected by the LRU equipment once every period, the detection state of the LRU equipment is judged, corresponding detection steps are executed, state migration is carried out, and PBIT detection is completed.
本申请属于具体涉及一种飞机飞行前自检测方法,包括:将LRU设备划分为A类设备、B类设备、C类设备,其中,A类设备检测直接读取其他已完成的自检测结果作为PBIT检测结果;B类设备需以VMC驱动进行检测,配置零位、施加激励或撤销激励;C类设备为自主检测设备,VMC发送检测指令,自动执行检测,VMC延时读取检测结果;对所有C类设备进行并行检测,同时串行执行A类设备、B类设备的检测;配置每个LRU设备的检测在一个函数单元中实现;对各个LRU设备的检测状态进行建模;PBIT主函数每12.5ms调度执行一次,PBIT主函数每周期调度所有LRU设备检测的函数单元一次,判断LRU设备所处的检测状态,执行对应的检测步骤,进行状态间的迁移,完成PBIT检测。
