摘　　要：为实现浮标系统全天候、全天时的海洋数据采集,设计并实现了一套适用于浮标系统的水下传感器供电及通讯系统,预期技术指标为传输功率达到20 W,效率50%以上,数据传输正确率99%以上。系统采用浮标的系泊线缆作为传导介质,通过两级电磁耦合进行水上及水下的能量及数据的传输,采用合理的水上水下电路设计保证了模块的稳定工作及低功耗运行,利用可靠的通讯协议设计保证了数据的有效传输。只需在该平台的水下系统上挂接不同的传感器即可实现对各种水文数据的实时测量。对系统的测试表明该系统能够实现设计功能,运行稳定,效率较高。In order to implement sea data collection in all-weather and all-time condition, a power and data transmission platform was designed and established for the buoy system. The expected parameters were： 20 W transmission power, transmission efficiency over 50% and communication accuracy over 99%. Using mooring cable of the buoy as the transmission medium, the system transmitted power and data between above-water and underwater modules by electromagnetic coupling. The module＇s stability and high power efficiency were achieved by reasonable circuit design. The robustness of data transmission was guaranteed by reliable communication protocol design. All kinds of hydrologic data could be measured by attach different kinds of sensors to the underwater module of the platform. Test on the platform shows that the system can realize its designed functions and works stably and efficiently.
