Intelligent power-off control system

The invention discloses an intelligent power-off control system. The intelligent power-off control system comprises a battery on-off execution circuit, a power-off control circuit and a load and output feedback circuit. The power-off control circuit comprises an emergency stop differential control unit, a power switch control unit, an isolation driving unit and a state judgment unit. The state judgment unit is used for sending signals to the isolation driving unit when receiving the signals of the load and the output feedback circuit; the emergency stop differential control unit is used for sending a signal to the isolation driving unit when a second switch returns to the closed state when a first switch is closed; the isolation driving unit is used for controlling the power switch controlunit to be disconnected when receiving a signal of the emergency stop differential control unit or the state judgment unit; and the power switch control unit is used for controlling a third switch tobe closed when the first
