Abstract:Hydrologic meteorological observation is an important part of the ocean environment observation, in order to meet the communication needs of different observation environment, the system based on satellite communication technology, serial communication technology, Ethernet technology was designed. The system collect hydrological meteorological data though XZY3 meteorological data collector and SCA11 Water Level Sensor, complete data docking through the multi-communication. The system realizes the data analysis, communication protocol conversion and external data communication, data graphical display and database storage. The system can display accurate hydrologic meteorological observation data and complete with different terminal equipment of the real-time data communication.
