一种田间信息无线远程传输系统的设计

Design of Wireless Remote Transmission System for Field Information

针对传统的田间信息采集技术耗资费时的问题,设计了一种田间信息无线远程传输系统,能够快速、经济地实现田间空间和属性信息的无线远程传输。系统集成应用先进的微控制器、GIS、GPS和GSM技术,采用AT89C52单片机为控制中心,GPS接收机为定位设备,水分测试仪作为田间信息获取传感器,GSM终端模块为信息传输媒体,为解决田间信息远距离传输的实时性问题提供了一种有效方法。

Time-consuming and high cost is a serious problem for conventional field information collection in precision farming. The objective of this study was to design a wireless remote transmission system, which could transmit field spatial and property information rapidly and economically. A transmission system integrating single-chip computer, global positioning system （GPS） and global system for mobile communications （GSM） technologies was developed. The system employed a single-chip AT89C52 unit as the control center, a GPS receiver as the locating device, a moisture test apparatus as the field property acquiring sensor and a GSM terminal module for data transfer, which could effectively solve the problem of time-consuming and high cost in field information remote transmission. This paper provides key technology for the development of equipment for rapid information acquisition and processing and offers information basis to agricultural management decision-making and intelligentzed variable control technology in precision farming.
