Study on the Field Information Remote Collection System Based on GPS,EDGE and LabVIEW Technology

为了高效实时地采集农田信息,实现农业生产的精细管理,设计出一种基于GPS、EDGE和LabVIEW技术的农田信息远程采集与监测系统。该系统采用自行设计的基于单片机、GPS和传感器技术的多参数农田信息采集仪,实现对土壤含水量、土壤温度、土壤电导率、环境温湿度等农田信息的快速定位测量。通过EDGE模块,利用移动EGPRS技术覆盖面广、传输速度快、资费低等特点,将测量所得数据快速实时传送至上位机。该系统的上位机系统把EDGE模块接收的数据存入数据库,并对其进行分析。该系统通过应用多功能信息采集设备和高速网络传输技术,实现对农田信息的实时、高效、精确和低成本采集,对精细农业作业决策具有广泛的应用价值。

In order to collect field information efficiently and achieve precision management of agriculture production, a system was designed, which could remotely collect and monitor the field information based on GPS, EDGE and the software of LabVIEW technology. The field information included moisture content, temperature and conductivity of soil lastly, and temperature and humidity of environment. These information have been measured and positioned by using a self-designed multi-parameter field information collection instrument based on the single-chip, GPS and sensor technology. Using the characteristics of wide coverage, fast transmission, low cost of EDGE technology, measured data were transmitted to PC in real-time through the EDGE module. Measured data were transmitted into database by EDGE module and was stored and analyzed. The system using multi-functional information collection instrument and high-speed transmission technology have achieved collection for field information in real-time, efficient, accurate and low-cost, and has a wide range of applications in precision agriculture decision-making.
