The invention discloses a power supply network protection module, which is connected between a storage battery and a generator, and comprises a system input unit for carrying out redundancy sampling on analog signal input of external equipment and sampling digital signal input; the fault judgment unit judges the fault state of the current power supply network protection module according to the fault definition; the current fault state of the power supply network protection module is judged according to digital signal input; the disconnection arbitration unit is used for arbitrating whether the power supply network protection module needs to be disconnected or closed according to the fault state output by the fault judgment unit and the disconnection and closing signal output by the self-recovery unit; the self-recovery unit performs self-recovery and then outputs a closing signal to the disconnection arbitration unit, and the disconnection arbitration unit notifies the system output unit to control the power supply network protection module to perform closing or stop self-recovery; and the system output unit outputs a control signal to the pre-drive chip to control the power supply network protection module to be switched off and switched on according to the switching-off and switching-on signal output by the switching-off arbitration unit.

    本发明公开了一种电源网络保护模块,其连接在蓄电池和发电机之间,包括:系统输入单元对外部设备模拟信号输入进行冗余采样和对数字信号输入进行采样;故障判断单元根据故障定义判断当前电源网络保护模块的故障状态;其根据数字信号输入判断当前电源网络保护模块故障状态;断开仲裁单元根据故障判断单元输出的故障状态和自恢复单元输出的断开闭合信号进行仲裁是否需要断开或闭合电源网络保护模块;自恢复单元进行自恢复后输出闭合信号至断开仲裁单元,断开仲裁单元通知系统输出单元控制电源网络保护模块进行闭合或停止自恢复;系统输出单元根据断开仲裁单元输出的断开闭合信号,输出控制信号至预驱芯片控制电源网络保护模块断开闭合。
