摘　　要：受海底复杂环境影响,海洋气象浮标信号衰减变化幅度较大,导致出现海洋气象浮标碰撞预警精度较低的问题,因此提出基于多传感器数据的海洋气象浮标碰撞预警方法。融合多个传感器的数据,采集海洋气象浮标坐标方位数据。考虑噪声干扰,结合RSSI接收信号强度测距法,计算节点间的距离。综合考虑浮标节点对目标定位的水下环境复杂程度,定位浮标节点。根据多传感器获取的目标坐标,结合加速度计算结果,实现碰撞预警。测试结果表明,所研究方法在1~1.25 m、1.25~2.5 m、≥4.0 m波高区间内,需要对气象浮标碰撞进行预警。在2.5~4.0 m波高区间内,无需对气象浮标碰撞进行预警,与实际情况一致。Due to the complex underwater environment,the attenuation and variation of ocean meteorological buoy signals are significant,resulting in low accuracy of collision warning for ocean meteorological buoys.Therefore,collision warning method for ocean meteorological buoys based on multi⁃sensor data is proposed.Integrate data from multiple sensors and collect coordinate and azimuth data of marine meteorological buoys.Considering noise interference,combined with RSSI receiving signal strength ranging method,calculate the distance between nodes.Considering the complexity of the underwater environment where buoy nodes locate targets,locate buoy nodes.Based on the target coordinates obtained from multiple sensors and combined with the acceleration calculation results,collision warning is achieved.The test results indicate that the studied method requires early warning of meteorological buoy collisions within the wave height range of 1~1.25 m,1.25~2.5 m,and≥4.0 m.Within the wave height range of 2.5~4.0 m,there is no need to provide warning for meteorological buoy collisions,which is consistent with the actual situation.
