Metro is a high-risk area of terrorist attacks. Although the method of manual security check is generally adopted in domestic subway, the traditional security check method has big loopholes due to the large number of passengers and long lines. This paper argues that, on the basis of the traditional metro security mode, the front end of video should be mainly reconstructed and the video monitoring system should be upgraded, so that it can have the functions of intelligent monitoring, intelligent command, intelligent research and judgment, and intelligent disposal, so that the subway anti-terrorism and effective platform can exert its maximum effectiveness. Introduction At present, international terrorism is rampant. Shopping malls, railway stations, bus stations, pedestrian streets, urban rail transit hubs and other public places with dense crowds have become the focus of terrorist attacks. In particular, the metro system has tunnel-like running lines, viaduct type closed track, closed narrow underground space, open platform and loose safety management. When earthquakes, collapses, floods, fires and other disasters come, or be subjected to such terrorist attacks as explosions, poison gas, arson, shooting, or slashing, Or in case of power failure, collision, failure, outage or other accidents, Or in case of power failure, collision, failure, outage or other accidents, or fighting, arguing, seat grabbing, stopping cars, jumping off rails and other emergencies. It is very easy to cause serious danger and emergency of group death and group injury. Although there has been no terrorist attack on metro in China, many terrorist attacks on subway in foreign countries have long sounded the alarm. For example, on 11March 2004, a bomb attack on a commuter train in Madrid killed 191 people and injured 1800 others. On 7 July 2005, 4Britons directed by al-Qaeda blew themselves up on three London subways stations during the morning rush hour, killing 52 passengers. On the morning of 29 March 2010, two “black widows” blew themselves up in a Moscow subway station, killing 38 people, and so on.
