摘　　要：针对农业对象具有的多样性、多变性、以及偏僻分散等特点,提出了一种基于GPRS和WEB技术的远程数据采集和信息发布系统方案。首先,通过RS-485总线与数字传感器连接,并与具有嵌入式系统和TCP/IP协议的现场监控模块构成监控系统;其次,通过GPRS建立现场监控系统与互联网的连接,将实时采集信息发送到WEB数据服务器。系统软件核心技术系MS VB.NET和ASP.NET开发而成,构建了基于B/S(Browser/Server)的服务模式,只要通过浏览器不仅可实时浏览监测数据,而且能进行历史数据的查询。实验表明该设计方案非常适合分散远距离条件下农业环境信息的获取、传输与应用。Aimed at the characteristics of the diversity, volatile variation,remote distribution for agricultural objects, a technical solution of a GPRS and Web based monitoring and publishing system for greenhouse environment information was presented. Firstly, a RS-485 bus cable as a middle bridge are used to connect digital sensors and a module with embedded system and TCP/IP protocol together forming a field monitoring system. Secondly, the communication was established between field monitoring system and INTERNET through GPRS so that the real-time field data could be transmitted to the remote database server. The software was developed with Microsoft VB.NET and ASP.NET criterion under the B/S （Browser-Server） mode. In this mode, users not only could check real time data coming from remote field site, but could visit historical data just by a client browser. The result showed that this system provided a flexible solution to get various environmental information distributed in remote and diverse agricultural spots.
