无人值守海洋气象仪系统设计

Design of Unmanned and Automatic Hydrometeorological Observation System in Oceanic Station

针对传统海洋气象仪传感器种类繁多、系统集成度低、信息处理和通信能力弱等问题,研究基于数字多功能传感器组件、嵌入式控制器及无线通信模块的无人值守型海洋气象仪。采用数字式传感器,实现对风速、风向、气压、气温、湿度、降雨量及能见度的测量,具有功能集成度高、测量误差小、抗干扰能力强的优点;采用FPGA实现传感器信息接收与显示,采用ARM完成对传感器信息的处理、存储、发送及系统控制,采用"北斗"模块完成信息传输与远程遥测,系统具有性能高、功耗低、可靠、易维护升级等特点。

There is low integration, poor ability of information processing and communication in common automatic hydrometeorological observation system （HAOS） which is combined with many different sensors. An unmanned and automatic hydrometeorological observation system working in oceanic station is researched in this paper, which is based on multi-functional digital sensor, embedded controller and wireless communication module. The advanced digital sensor can measure wind-speed, wind-direction, pressure, temperature, humidity, volume of rainfall and visibility; it has the advantage of high integration, little deviation of measurement, and good anti-interference. The FPGA module can receive and display the data from sensors. The ARM module can process, store and send data. The Beidou module can accomplish data communication. The system has the advantage of high-performance, low power loss, high reliability and low maintenance requirements.
