基于虚拟仪器技术的农业气象自动观测系统研究

Research on Agricultural Meteorological Automatic Observation System Based On Virtual Instrument Technology

基于虚拟仪器技术,以可编程数据采集器cFP和LabVIEW语言平台为核心构建的自动数据采集系统,具有较高的模块化和可扩展性,在各类型传感器和无线通信技术的配合下,可实现多类型多频次数据采集、传输、信号分析、处理、显示和存储的全程自动化。系统集成了多角度图像/声音自动采集装置,可实时捕捉环境及观测对象的特征变化。在此基础上,以农田生态系统为主要对象设计的农业气象自动观测系统针对性强、集成性好,既突出农田生态系统的观测特点,又能灵活扩展,不仅为野外生态环境及农业气象的长期观测提供了可行之道,也可作为其它各类生态子系统或不同环境条件下自动观测研究的参考。

This paper found the automated data acquisition system,which was built on the basis of virtual instrument,programmable data acquisition unit CFP and Lab VIEW language platform,was more modularized and expandable,and it could realize the automation for collecting,transmitting,signal analyzing,disposing,displaying and storing of polytypic and high frequency data with coordination of sensors and radio communication technology.Besides these,this system integrated multi-angle image / sound automatic collection device,and could real-time catch characteristic change on environment and objects.Based on these,the agricultural meteorological automatic observation system designed for farmland ecosystem,with greater pertinence and integration can both highlight the specialty of observing in farmland ecosystem and expand neatly.This system could not only provide some method for outdoors and agricultural meteorology long-term observation,but also offer some suggestion for research on automatic observation in different environment or other ecological subsystem.
