The embodiment of the invention discloses a fault diagnosis method and device for an aircraft thermal management system, electronic equipment and a storage medium, and the method comprises the steps: obtaining the shutdown time of an aircraft under the condition that the aircraft is detected to be powered on; the initial temperature of cooling liquid before the aircraft is powered on is determined according to the shutdown duration; performing cyclic detection operation based on the initial temperature of the cooling liquid to obtain the limited temperature of the cooling liquid of a target part in the aircraft thermal management system, and obtaining the identification temperature of the cooling liquid of the target part; and performing fault diagnosis according to the cooling liquid identification temperature and the cooling liquid limit temperature of the target part. Thus, on one hand, a water temperature sensor does not need to be additionally arranged in the thermal management system, and system diagnosis false alarm or missing alarm caused by sensor faults can be avoided; and on the other hand, through the cooling liquid identification temperature and the cooling liquid limit temperature of the target part, the diagnosis process can be simplified, and more accurate fault diagnosis can be made.

    本申请的实施例揭示了一种飞行器热管理系统的故障诊断的方法、装置、电子设备及存储介质,该方法包括:在检测到飞行器上电的情况下,获取飞行器的停机时长;根据停机时长确定飞行器在上电前的冷却液初始温度;基于冷却液初始温度进行循环检测操作,获得飞行器热管理系统中目标零部件的冷却液限定温度,并获取目标零部件的冷却液识别温度;根据目标零部件的冷却液识别温度和冷却液限定温度进行故障诊断。这样,一方面,无需在热管理系统中增设水温传感器,能够避免由于传感器故障导致的系统诊断误报或漏报;另一方面,通过目标零部件的冷却液识别温度和冷却液限定温度,能够简化诊断流程,做出更准确的故障诊断。
