The invention discloses a health management system for an electric drive system. The health management system comprises a state parameter obtaining module which obtains state parameters of the electric drive system; a state monitoring module which performs feature extraction on the state parameters to output feature information of a health state, and sends the feature information to a fault diagnosis module, a fault prediction module and a health management module; the fault diagnosis module which processes the feature information, outputs diagnosis information of a fault state and sends the diagnosis information to the fault prediction module and the health management module; the fault prediction module which predicts the received information and outputs the remaining service life of theelectric drive system; and the health management module which processes the received feature information of the health state, the diagnosis information of the fault state and the remaining service life of the electric drive system and outputs a maintenance strategy. By calculating the collected information, the health management of the electric drive system is realized, the design efficiency of the management system is improved, and a guarantee is provided for the safe and reliable operation of the electric drive system in the whole life cycle.

    本发明公开了一种用于电驱动系统的健康管理系统,包括:状态参数获取模块获取电驱动系统的状态参数;状态监测模块对状态参数进行特征提取输出健康状态的特征信息,发送给故障诊断模块、故障预测模块及健康管理模块;故障诊断模块对特征信息处理输出故障状态的诊断信息,并将诊断信息发送给故障预测模块及健康管理模块;故障预测模块对接收到的信息进行预测输出电驱动系统的剩余使用寿命;健康管理模块对接收的健康状态的特征信息、故障状态的诊断信息及电驱动系统的剩余使用寿命进行处理输出维保策略。本发明通过对收集的各信息进行计算,实现对电驱动系统的健康管理,提高管理系统设计效率,为电驱动系统全生命周期安全、可靠地运行提供保障。
