无线传感网络的应用已经逐渐由陆地发展到海洋。海洋观测数据与水下声学感知信息实时、高效、精准上传至岸基或母船，离不开无线传感网络中的数据传输系统与通信协议的协调搭配。通过软件仿真分析无线电台传输频率与系统数据通信协议传输误码率间的关系，搭建无线数据传输系统，实现数据收发功能，完成了外场湖面单节点无线电台拉锯通信。根据测试结果进行了多节点无线电台收发数据拥塞、信号串扰以及数据价值等相关领域研究。最后对海面无线数据传输系统进行功能分析，基于系统完备性的数据通信协议满足无线数据传输系统通信距离大于6 km的性能指标需求，为进一步实现海洋无线局域多传感器网络融合、打造智慧海洋提供有力支撑。
The application of wireless sensor network has gradually developed from land to ocean. Ocean observation data and underwater acoustic sensing information are uploaded to shore-based or mother ship in real time, efficiently and accurately, and it is inseparable from the coordination and combination of data transmission system and communication protocol in wireless sensor network. This paper analyzes the relationship between the transmission frequency of the radio station and the transmission error rate of the system data communication protocol through software simulation; and builds a wireless data transmission system to realize the data receiving and sending function, and completes the outfield lake single-node radio station see-saw communication. According to the test results, researches on the data congestion, signal crosstalk and data value of multi-node radio stations have been carried out. Finally, the function of the sea surface wireless data transmission system is analyzed, and the data communication protocol based on the completeness of the system meets the performance index requirements of the wireless data transmission system with a communication distance of more than 6 kilometers. Provide strong support to further realize the integration of marine wireless local multi-sensor networks and build a smart ocean.
