Method and system for monitoring lubricating oil low-pressure sensing system of aircraft engine

The invention discloses a monitoring method and system for a lubricating oil low-pressure sensing system of an aircraft engine, and the method comprises the steps: monitoring a first engine parameter of the engine in a starting stage and a shutdown stage, and carrying out the event triggering condition detection; when the event triggering condition is met, a second engine parameter is obtained, and an early warning message is generated according to the second engine parameter; and carrying out accumulative analysis on the early warning message, and carrying out fault prediction on the lubricating oil low-pressure sensor according to an accumulative analysis result of the early warning message. According to the method, the abnormal state of the lubricating oil low-pressure sensor can be automatically identified and monitored, and faults of the engine lubricating oil low-pressure sensor can be timely and accurately detected, so that delay events are avoided, and the safety of an aircraft is guaranteed. 本发明公开了一种
