一种湖泊浮标近距离无线调制解调器设计

摘要

从千米级近距离通信具体要求出发，选择低功率甚高频无线电通信模块，设计1200bit/s调制解调器，集成到湖泊水文监测浮标终端机中，完成浮标站到岸站的遥测数据近距离传输，通信协议符合 CCITT-V23标准。应用实践表明通信链路稳定可靠，还可以在水库、入海口和近海进行水文水生态测验推广应用。%From specific requirements of short range communication at kilometer level, it choices low-power VHF radio communication module, designs 1200 bit/s modem, integrates into a lake hydrological monitoring buoy terminal, and completes telemetry data transmission from buoys close to shore station. The communication protocol agreement conforms to CCITT-V23 standard. The application practice shows that communication links are reliable, and the system can be spreaded in reservoirs, estuaries and coastal hydrological aquatic ecosystems.
