摘　　要：水库、航道等水域的水下地形测量对安全生产至关重要,针对传统方法采用人工测船周期长、成本高的缺点,设计了基于无线传感器网络的水下地形监测方法.该方法利用自行设计的无线水深测量节点,首先采用二维定位算法计算节点平面坐标,并利用超声波测距传感器获得垂直深度坐标,然后利用所有节点的三维坐标进行曲面拟合,重建水下地形.试验和仿真结果表明:该方法有效可行,具有一定的实用价值.Underwater terrain survey is particularly important in safety production for reservoirs and channels. Compared with the high cost and long cycle of traditional artificial surveying method,this paper develops a surveying approach for underwater terrain based on wireless sensor networks. The wireless node is designed to survey the depth of water,with the help of two-dimensional localization algorithm to calculate the nodes＇ plane coordinates and that of ultrasonic sensors to obtain the vertical depth coordinates,then the three-dimensional coordinates of all the nodes are used to fit the surface and rebuild the underwater terrain. The results of test and the simulation show that the method is effective and feasible,with a certain practical value.
