According to the Vxworks-based fuel oil supply system real-time fault diagnosis method disclosed by the invention, when processing resources allocated by Vxworks are obtained, a fuel oil pressure value, a fuel oil pressure alarm value, a power supply state of a booster pump and a rotating speed of an engine fuel gas generator are obtained in real time, then the working state of the fuel oil supply system is judged according to the fuel oil pressure value, and a fault diagnosis result is obtained according to the working state of the fuel oil supply system. A diagnostic logic corresponding to the working state is selected to carry out fault diagnosis on a booster pump and a fuel pressure sensor in the fuel supply system according to whether the fuel pressure value triggers a fuel pressure alarm value or not, the power supply state of the booster pump and the rotating speed of an engine gas generator; wherein the power supply state information of the booster pump and the rotating speed of the fuel gas generator of the engine are obtained through an airborne bus, and the fuel pressure value and the fuel pressure alarm value are obtained through an acquisition circuit. According to the invention, fault diagnosis can be reliably carried out in real time.
本发明公开的一种基于Vxworks的燃油供油系统实时故障诊断方法，当获得Vxworks分配的处理资源时，实时获取燃油压力值、燃油压力告警值、增压泵的供电状态、发动机燃气发生器转速，然后根据燃油压力值对燃油供油系统的工作状态进行判断，再选择工作状态对应的诊断逻辑根据燃油压力值是否触发燃油压力告警值、增压泵的供电状态、发动机燃气发生器转速对燃油供油系统中的增压泵和燃油压力传感器进行故障诊断；其中，增压泵的供电状态信息和发动机燃气发生器转速通过机载总线获取，燃油压力值和燃油压力告警值通过采集电路获取。本发明能够实时且可靠地进行故障诊断。
