基于CAN总线的地面自动气象观测集成系统

Surface Meteorological Auto-observation System Based on CAN Bus

随着气象业务领域进一步深入拓展,嘉兴市气象局从2006年起,增加了紫外线、下垫面温度等特种要素观测,并与江苏省无线电科学研究所合作研发了地面自动气象观测集成系统。该系统基于CAN总线,由中心站计算机,综合观测系统业务软件及各种分采集器组成,具备积木式扩充特点,能根据需求扩充气象要素,系统采用Microsoft VB 6.0作为开发工具,后台数据支持MS SQL Server2000专业版,采用C/S架构,适合多点多要素方式监测。该自动气象观测集成系统集数据查询、统计计算、报警监控等一体,具有可扩性好、稳定性高、信号衰减小、功能完备、运行稳定、界面友好等特点,能满足气象业务日益拓展的需要,适合在全国气象业务部门推广使用。

With the further expansion of weather service,the monitoring of special elements,such as ultraviolet radiation and underlying surface temperature,has been added to the daily meteorological observation in Jiaxing Meteorological Service since 2006,and the surface meteorological auto-observation system has been accomplished based on the CAN bus in cooperation with by the Wireless Scientific Research Institute of Jiangsu Province.The system is composed of the central station computer,integrated observing service software,and various sub-collectors.Characterized with the cordwood-like expansion style and equipped with Microsoft VB6.0 as a development tool,the professional version of MS SQL Server 2000 based on the backstage database,and C/S as architecture,the system works satisfactorily for the multi-point and multi-elemental monitoring,can be widely applied in data query,statistical calculation,alarm monitoring,etc.Having excellent stability,minor signal attenuation,perfect capabilities,and friendly interface,and being easy to be expanded,the system can meet the increasing needs of meteorological service and be widely employed throughout the nation.
