Excavator fault diagnosis method, excavator, electronic equipment and readable storage medium
The invention provides an excavator fault diagnosis method, an excavator, electronic equipment and a readable storage medium. The method comprises the steps that parameter data of the excavator in a preset time period and the environment temperature of the place where the excavator is located are obtained, wherein the parameter data comprise the actual cooling water temperature of an engine, the rotating speed of the engine and the oil consumption of the engine; based on the environment temperature, the rotating speed of the engine, the oil consumption of the engine and a first cooling water temperature model, the theoretical cooling water temperature of the engine of the excavator is calculated; and based on the actual cooling water temperature of the engine and the theoretical cooling water temperature of the engine, fault diagnosis is conducted on the excavator. According to the method, abnormality is found before the actual cooling water temperature of the engine reaches the alarm value, the fault of the excavator is judged and processed in advance, and fault expansion is prevented.
本发明提供一种挖掘机故障诊断方法、挖掘机、电子设备及可读存储介质，该方法获取挖掘机在预设时间段内的参数数据和挖掘机所在地的环境温度，所述参数数据包括发动机实际冷却水温、发动机转速以及发动机油耗；基于所述环境温度、所述发动机转速、所述发动机油耗以及第一冷却水温模型，计算所述挖掘机的发动机理论冷却水温；基于所述发动机实际冷却水温与所述发动机理论冷却水温，对所述挖掘机进行故障诊断，该方法在发动机实际冷却水温达到报警值之前发现异常，提前对挖掘机的故障进行判断和处理，防止了故障的扩大。
