The invention discloses an automobile power supply management system, which is characterized in that an MCU (Microprogrammed Control Unit) of each fuse box acquires circuit data corresponding to a plurality of automobile circuits through an A/D (Analog to Digital) acquisition module, and the MCU judges the working state of the automobile circuits based on the circuit data and transmits the working state to an ECU (Electronic Control Unit) or a VCU (Vehicle Control Unit) of an automobile for external display; when an automobile breaks down, an abnormal automobile circuit is found through an ECU or a VCU of the automobile, automobile electric appliances and fuse boxes corresponding to the abnormal automobile circuit are rapidly found by means of automobile circuit arrangement information pre-stored in the ECU or the VCU of the automobile or arrangement specifications of the automobile circuits in the industry, and after the fuse boxes corresponding to the abnormal automobile circuit are opened, the automobile electric appliances and the fuse boxes corresponding to the abnormal automobile circuit are rapidly found out. A fuse corresponding to an abnormal automobile circuit can be quickly found by observing the light emitting condition of each LED working lamp; the technical problem that a fault automobile circuit and a corresponding fuse position are difficult to quickly determine based on a fuse box at present can be effectively solved, and the effect of high automobile fault removal speed is achieved.
本发明公开了一种汽车电源管理系统,各保险盒的MCU通过A/D采集模块采集对应多个汽车电路的电路数据,MCU基于电路数据判断汽车电路的工作状态并传递至汽车的ECU或VCU以便对外展示;当汽车出现故障时,通过汽车的ECU或VCU找到异常的汽车电路,并借助汽车的ECU或VCU中预存的汽车电路布置信息或行业内对于汽车电路的布置规范快速找到异常汽车电路所对应的汽车用电器和保险盒,打开异常汽车电路对应的保险盒后,可通过观察各LED工作灯发光情况快速找到异常汽车电路所对应的保险丝;可有效解决目前基于保险盒难以快速确定故障汽车电路和对应保险丝位置的技术问题,取得汽车故障排除速度的效果。
