摘要

针对车辆运行过程中部分继电器和接触器发生偶发性故障的问题，基于边缘计算理念，设计了一种适用于电气屏柜的健康管理装置，通过实时高速采集电气屏柜中关键电路的电压和电流基本数据，结合识别算法模型，实现电气屏柜全生命周期的实时监视、状态评估、逻辑控制分析、故障诊断和剩余寿命预测。因此，该健康管理装置能有效提升电气屏柜的自感知和健康状态管理能力，保障车辆更安全可靠运行，同时还可促进电气屏柜智能化检修，优化运维成本。

Abstract

In view of the accidental malfunction of relays and contactors during the operation of vehicles, a health management device for electrical cabinets was presented based on the concept of edge computing in this study. Specifically, the data of voltage and current of the key loops of electrical cabinets were obtained through health management device in real time with a high speed, the real-time monitoring, status assessment, logic control analysis, malfunction diagnosis and residual life prediction throughout the life cycle of electrical cabinets could be achieved based on a recognition algorithm model. Hence, the health management device can improve the self-perception and health management capability of electrical cabinets and thus make vehicles more reliable. The usage of the device can also beneficial to the intelligent maintenance of electrical cabinets and optimize maintenance costs.
