The network port on-off controller 1 is of a box body structure, adopts the size of a standard switch, and is suitable for a standard screen cabinet in a transformer substation; one side of the controller is provided with 24 RJ45 network cable interfaces 3, and 12 groups of control circuits are arranged in the controller; the two RJ45 network cable interfaces 3 are connected into a group of control circuits, and the two RJ45 network cable interfaces 3 can be connected or disconnected through the on-off power of the control circuits; the 12 groups of control circuits are all connected with the MCU 4, and the MCU 4 can control the power on and off of any control circuit. The MCU 4 is an MCU 4 used by the existing master station.

Further, the embodiment also provides a specific setting of the control circuit;
