The power distribution module provided by the invention comprises a main control unit, a micro-control unit, an output driving unit and a slope driving control unit, the main control unit is connected with the micro-control unit and is used for driving the micro-control unit to operate and monitoring the operation state of the micro-control unit; the output driving unit is in communication connection with the micro-control unit; the slope driving control unit is connected with the main control unit and the output driving unit respectively; the main control unit is used for starting and stopping the slope running control unit according to the change of the running state of the micro-control unit; the output driving unit and the slope control unit form a feedback loop; and the slope control unit is configured to receive a driving signal fed back by the output driving unit through the feedback loop and drive the output driving unit to output the driving signal when the main control unit monitors that the running state of the micro-control unit is invalid. By arranging the slope control unit, the power supply state of the power supply distribution module can be kept when the micro-control unit fails.
本发明提供的电源分配模块包括主控制单元、微控制单元、输出驱动单元及坡行控制单元;主控制单元与微控制单元连接,用于驱动微控制单元运行和监测微控制单元之运行状态;输出驱动单元与微控制单元通信连接;坡行控制单元分别与主控制单元和输出驱动单元连接;主控制单元用于根据微控制单元之运行状态的变化以启停坡行控制单元;输出驱动单元还与坡行控制单元形成一反馈回路;坡行控制单元被配置为,当主控制单元监测所述微控制单元之运行状态为失效时,通过反馈回路接收输出驱动单元反馈的驱动信号,并驱动输出驱动单元输出所述驱动信号。通过配置坡行控制单元,可在微控制单元失效时保持电源分配模块的电源状态。
