【摘要】：因我国城市发展速度不断加快、城市人口的数量也随之不断增加,经济发展速度越来越快,车辆行驶不断增加,致使我国交通状况拥堵不堪。普遍存在车辆堵塞、交通秩序混乱、道路拥挤等情况。改变交通方式(如地铁、轻轨)能够改善城市交通所面对的困境。地铁安全同样存在隐患,由于地铁深埋地下,环境封闭,人员密集,复杂且流动性大,如果有事故发生,将造成不可估量的损失。因此人们已经将关注的焦点转移到地铁灾害的预测与控制上。本文采用基于无线红外传感器网络来构建地铁隧道安全检测系统,系统能在短时间内对隧道中是否有人做出判断,实现早期报警,让列车及时制动避免造成意外事故用红外热释传感器监测是否有人员通过,再用Zigbee无线传输模块CC2530对传感器监测到的信息进行处理了和传输。最终将信息传送到FPGA开发板进行判断和报警并显示被测人编号。经实验验证,本文所设计的安全监控系统的整体检测率为91.1%,实验结果表明该系统能够完成对人员流动现象的监测,能够应用到地铁隧道或封闭的敏感场所,同时该系统具有良好的扩展性。
[Abstract]:Because the speed of urban development is speeding up, the number of urban population is increasing, the speed of economic development is getting faster and faster, and the number of vehicles is increasing, which leads to the traffic jam in our country. There are widespread traffic congestion, traffic disorder, road congestion and so on. Changing the mode of transportation (such as subway, light rail) can improve the plight of urban traffic. Subway safety also has hidden dangers, because of underground deep buried, closed environment, dense people, complex and mobile, if there is an accident, it will cause inestimable losses. Therefore, people have shifted the focus of attention to subway disaster prediction and control. In this paper, a subway tunnel safety detection system based on wireless infrared sensor network is constructed. The system can make a judgment on whether there is anyone in the tunnel in a short time, and realize the early alarm. The infrared thermoluminescence sensor is used to monitor the passage of people to avoid accidents caused by the train braking in time. Then the information monitored by the sensor is processed and transmitted by using Zigbee wireless transmission module CC2530. Finally, the information will be transmitted to the FPGA development board for judgment and alarm, and the number of the tested person will be displayed. The experimental results show that the overall detection rate of the safety monitoring system designed in this paper is 91.1%. The experimental results show that the system can monitor the human mobility phenomenon and can be used in subway tunnels or closed sensitive places. At the same time, the system has good expansibility.
