The present invention discloses a terminal 'crash' fault removal device for cable transmission IP address positioning. The device comprises a main station computer, a switch, a terminal and a power strip. The terminal 'crash' fault removal device is characterized in that a relay, a control circuit board of the relay and a power supply control module are arranged in the power strip; a relay control circuit is connected with a data processing module of a single-chip microcomputer; the single-chip microcomputer is equipped with the data processing module, a TCP network protocol unit and an IP address; and the on-off action of the relay is controlled by the TCP network protocol unit so as to control the power-off or restart of an electric energy terminal of a gateway. The device disclosed by the invention is simple in circuit principle, ensures that address passwords can be quickly and accurately determined, cannot be limited by external environmental conditions, is reliable in action, low in manufacturing cost and easy in installation, can be used for effectively and timely restarting the terminal power supply through remote control when the terminal has a 'crash' fault, and ensures that rapid removal can be achieved, and the time delay and long-time channel interruption can be avoided.
