基于WSAN的道路积水监控系统的设计与实现

Design and Implementation of Road Waterlogging Monitoring System Based on WSAN

摘要:

强降雨及城市排水系统的老化,使得城市道路低洼处积水严重,对市民人身安全、财产、路基、城市交通产生不容忽视的影响;针对该问题,采用无线传感器/执行器网络(WSAN)技术,设计了道路积水监控系统;该系统分为传感/执行层、网络层和应用层三层;传感/执行层的传感器节点使用超声波传感器采集积水信息,执行器节点使用执行器水泵进行排水；网络层网关及汇聚节点使用ZigBee网络和GPRS网络相结合来实现传感/执行层与应用层之间的数据双向传输；应用层服务器储存采集的道路积水信息,调用百度地图API将实时信息显示在web端,并通过网络层发送指令控制积水区域内的执行器水泵动作,实现闭环控制；该系统能够简洁有效地实现道路积水信息的实时共享,可以实现及时排水,具有实际的应用价值。

Abstract:

Heavy rainfall and aging urban drainage system make the low-lying road waterlogged seriously and have an important effect on the safety and property of citizens, roadbed and urban traffic. In order to solve this problem, the wireless sensor / actuator network (WSAN) technology is used to design a monitoring system. The system is divided into three layers:sensor / actuator layer, network layer and application layer. Ultrasonic sensors are deployed to collect the information of water level in sensor nodes of sensor / actuator layer, actuator pump is used to drain away the water in actuator nodes of sensor / actuator layer. The ZigBee network and GPRS network are configured for two-way data transmission between sensor / actuator layer and application layer in the gateway and sink node of network layer. The server of application layer stores the information of road waterlogging, calls Baidu map API to display the real-time information on the web, and sends commands to achieve closed-control by controlling the actuator pump in the road waterlogging area action through the network layer. The system not only shares the real-time information of the road waterlogging simply and effectively, but also realizes the timely drainage. So it has practical application value.
