Hydraulic motor fault detection method, device and system and excavator
The invention discloses a hydraulic motor fault detection method, device and system and an excavator. The hydraulic motor fault detection method comprises the following steps: respectively obtaining actual operation data of each operation characteristic quantity in a hydraulic motor operation characteristic quantity set in a preset time period; judging whether fault operation data exists in the multiple obtained actual operation data or not; when the fault operation data exists, obtaining a fault database, wherein the fault database comprises historical operation data of the operation characteristic quantity corresponding to the fault operation data under each fault; and determining the fault reason of the hydraulic motor according to the fault operation data and the fault database. Therefore, automation of data analysis during fault detection of the hydraulic motor can be realized, so that the efficiency and precision of fault detection are improved, and the labor cost is reduced.
本发明公开了一种液压马达故障检测方法、装置、系统及挖掘机，其中液压马达故障检测方法包括：分别获取液压马达运转特征量集合中的每个运转特征量在预设时间段内的实际运转数据；判断获取到的多个实际运转数据中是否存在故障运转数据；当存在所述故障运转数据时，获取故障数据库，所述故障数据库中包括与所述故障运转数据相对应的运转特征量在每个故障下的历史运转数据；根据所述故障运转数据和所述故障数据库确定所述液压马达的故障原因。由此可以实现液压马达故障检测时的数据分析自动化，从而提高故障检测的效率和精度，降低人力成本。
