Design Of Subway Tunnel Monitoring System Based On Infrared Sensor

With the rapid development of urbanization,The influx of a large number of urban migrants, Who go out and frequent exchange of material,Making urban transport situation facing a severe test,Traffic jams, chaotic traffic, road congestion situation has been prevalent in our major cities.Now, the focus of attention of the public in general has shifted to how to solve urban traffic problems.In this case,only to widen the road is not relying on mitigation and improve this situation. Rational use of limited land resources city,Extended Controls use conditions, and actively introduce medium and large passenger subway and light rail transportation,Is an inevitable trend.China’s urban rail transport, especially the Metro construction is facing unprecedented climax,However, due to the complex subway system, involving a large surface, difficult to manage, subway construction, commissioning and operation of all there is a big security risk,Accidents occurred frequently. Metro subway security situation is grim and losses of property,So subway disaster prediction and control has become the focus of attention.This paper presents a subway tunnel safety detection system based on wireless infrared sensor networks,The system can be constructed in a short time to judge whether someone tunnel,Achieve early warning,Let the train brake in time cause an accident.Wireless infrared sensor network as a wireless sensor network(WSN) is a subset,Compared with the high-speed, ultra-low power consumption and high real-time characteristics and other wireless sensor networks.Wireless infrared sensor networks,It is the main solution is in short range wireless communications technology,Meet the low-power, real-time performance and other requirements of the common good.Open ZIGBEE protocol stack can be defined for this set of communications standards.This article will focus on which part of the short-range wireless communication.The experimental verification, This article is designed to detect security monitoring system as a whole was 91.1 percent,Overall detection accuracy rate of 。Experimental results show that the system can complete mobility phenomena monitoring,It has practical value,can be applied to the subway tunnel or enclosed sensitive sites,Meanwhile, the system has good scalability.
