基于LabVIEW的农业气象环境监测系统设计

Design of Agricultural Meteorological Environment Monitoring System Based on LabVIEW

气象环境参数与农业息息相关,是农业智能化的重要参考数据,因此对农业气象环境的监测十分重要。以AT89S52单片机为主控芯片,结合各传感器模块、A/D转换芯片和计算机,搭建了一套农业气象环境监测系统硬件平台;以美国国家仪器公司的Lab-VIEW为软件开发平台,设计并编写了基于状态机程序架构的上位机软件,实现了友好的用户交互界面,完成了对空气温湿度、气压、光照、土壤温湿度、二氧化碳浓度、雨雪的实时测量、显示与记录等功能,并利用前面板网络发布功能实现了实时监测系统的局域网远程控制。

Meteorological environmental parameters are closely related to agriculture and are important reference data for agricultural intelligence.Therefore,monitoring of agricultural meteorological parameters is very important.Use AT89 S52 single-chip microcomputer as the main control chip and combining with some sensors,A/D conversion chip and computer,a set of agricultural meteorological environment monitoring system hardware platform is built;National Instruments’Lab VIEW is used as the software development platform,based on state machine program architecture,PC software is designed and programmed,which realizes a friendly user interface,completes the functions of real-time measurement,display and recording of air temperature and humidity,air pressure,illumination,soil temperature and humidity,carbon dioxide concentration,rain and snow,and realizes the remote control of the real-time monitoring system by using the front panel web publish.
