The invention provides an intelligent fuse box, which comprises an MCU (Microprogrammed Control Unit) and an MOSFET (Metal-Oxide-Semiconductor Field Effect Transistor) which are connected through a signal line, the MOSFET is respectively connected with a whole vehicle storage battery power supply wire harness and a load wire harness, the MCU is connected with other controllers on a vehicle through a CAN (Controller Area Network) communication interface, and the MCU is connected with a whole vehicle storage battery sensor through an LIN (Local Interconnect Network) communication interface; the voltage division acquisition circuit is used for sampling switching signals from each switching wire harness, and sending the sampled switching signals to the MCU after voltage conversion; and the MCU controls the corresponding MOSFET to be switched on or switched off through a voltage signal sent by the voltage division acquisition circuit, so that power supply or power failure for the corresponding load is realized.

    本发明提供了一种智能保险盒,包括:通过信号线相连接的MCU和MOSFET管,MOSFET管分别与整车蓄电池供电线束和负载线束连接,MCU通过CAN通信接口和车辆上其它控制器连接,MCU通过LIN通信接口和整车蓄电池传感器连接;分压采集电路,用于采样来自各开关线束的开关信号,并将采样到的开关信号经过电压转换后发送至MCU;MCU通过分压采集电路发送的电压信号来控制相应MOSFET管进行开或关,实现为对应负载供电或断电。
