The invention relates to the technical field of vehicle operation monitoring, and discloses a vehicle air conditioner refrigeration system abnormity early warning method and system.For each air conditioner refrigeration system on a vehicle and for each operation condition, an air conditioner refrigeration system early warning model is pre-stored, and the method comprises the steps that real-time operation data of each air conditioner refrigeration system is obtained; for each air conditioner refrigeration system, the operation condition of the air conditioner refrigeration system is determined according to the corresponding real-time operation data; calling a corresponding air conditioner refrigeration system early warning model based on the operation condition, and predicting the operation data at the next moment according to the current real-time operation data; and based on the preset threshold range of each operation data, whether the predicted value of each operation data is abnormal or not is judged, and if yes, the air conditioner refrigeration system and the specific part corresponding to the operation data are determined according to the source of the operation data. According to the invention, positioning from parts to a specific air conditioning refrigeration system and then to a specific compartment is realized, and timely maintenance is facilitated.

    本发明涉及车辆运行监测技术领域,公开了一种车辆空调制冷系统异常预警方法及系统,对于车辆上每个空调制冷系统,针对每个运行工况,均预先存储空调制冷系统预警模型,所述方法包括:获取各个空调制冷系统实时运行数据;对于每个空调制冷系统,根据相应实时运行数据确定所属运行工况;基于所述运行工况,调用相应空调制冷系统预警模型,根据当前实时运行数据对下一时刻的运行数据进行预测;基于各运行数据的预设阈值范围,判断各运行数据的预测值是否发生异常,若发生异常,根据所述运行数据的来源确定所述运行数据相应的空调制冷系统及具体部位。本发明实现了从部位,到具体空调制冷系统,再到具体车厢的定位,有助于及时维修。
