基于无线传感器网络的水深监测系统设计

Design of Water Depth Surveying System Based on Wireless Sensor Networks

摘要: 水深测量在水库、河道等水域的治理开发中尤为重要，针对传统测量方法成本高、周期长的缺点，该文采用无线传感器网络技术，设计了一套水深实时监测系统。该系统采用了自行设计制作的无线水深测量节点，通过超声波测距传感器测量水深数据，并通过倾角检测传感器进行校准，数据经处理后传输到客户端，可以使用户获取目标水域的实时水深变化信息，若大规模部署节点，可应用于水下地形的测量。初步试验表明该系统部署方便，测量精度较高，具有一定的实用性和推广价值。该文为无线传感器网络在水利测量方面的应用做出了探索性研究。

Abstract: Surveying depth of water is particularly important in the management and development of reservoirs and rivers. In view of high cost and long cycle of the traditional artificial surveying method, this paper develops a real-time water depth surveying system based on wireless sensor networks. In this system, we design a node used for surveying depth of water, which uses the ultrasonic ranging sensor to survey and the angle detection sensor to calibrate. The processed data transmitting to the client can enable users to obtain depth information of the target area in real time. If we deploy large-scale of node, it can be used to measure underwater terrain. Preliminary experimentations prove the convenient deployment, high accuracy, practicability and popularization value of the system. This paper contributes to the exploration research on the applications of WSN in hydraulic engineering survey.
