The invention discloses a scramming apparatus for an AGV (Automated Guided vehicle). The scramming apparatus for an AGV comprises an infrared obstacle avoidance detection apparatus, an alarm apparatus and a scramming apparatus, wherein the infrared obstacle avoidance detection apparatus is connected with a controller; the infrared obstacle avoidance detection apparatus reads the distance between the AGV body and an obstacle and feeds back the distance information to the controller; the alarm apparatus is connected with the controller; the distance information is smaller than a target distance prestored in the controller, and the controller sends the alarm information to the alarm apparatus to alarm; and the scramming apparatus is used for disconnecting power supply for the AGV body. The AGV protection system provided by the scramming apparatus for an AGV can emergently disconnect AGV power supply so as to stop the AGV at any time to improve the safety by means of setting of the scramming apparatus.
