摘要

地震灾后道路随时可能因余震再次塌方堵塞,需要实时监测其可用性。为此,提出一种灾后道路可用性监测系统。利用传感器覆盖半径、系统覆盖期望和冗余度对节点进行布置,并根据其传输特点设计路由的建立、转发和维护算法,给出多传感器信息综合的事件判断算法和图像采集方式。实验结果表明,当事件发生时,该系统能及时收到警报和图像信息。
After the earthquake,roads are subject to be blocked by landslides caused by aftershocks.To solve the problem of real-time monitoring of transport lifeline systems,the post-disaster road available monitoring system solution is put forward.Sensors selection and node configurations,node arrangement method,routing algorithm,multi-sensor information integrated algorithm,and image collection mode are discussed.Node arrangement is calculated by sensor coverage radius,expectations of the system coverage and system redundancy.In routing setup,the forwarding and maintenance algorithms are designed according to node arrangement and transmission characteristics.Experimental results show that the system can receive an alert and the image information in time when the event occurs.
