摘　　要：提出了一种针对温室环境监测的基于WEB的数据采集和信息发布系统设计方案,并从软、硬件的角度详细介绍了系统的实现方法。该系统应用MSVB.NET开发工具,采用ASP.NET技术规范,构建了B/S(Browser/Server)模式下的远程监控系统。硬件系统通过RS-485总线与数字传感器连接,并与具有联网功能的PC监控计算机构成温室现场监控系统。该系统不仅能够通过Internet远程浏览访问温室现场数据,而且能对系统运行参数进行远程修改和设置。该系统不仅可以实现对温室环境的异地和远距离数据监控管理,而且也可应用于农业的其它领域。In this paper, a technical scheme of a house environment data was presented firstly, and WEB based monitoring and publishing system for greenthe detailed description of the system was given to introduce the implementation of the hardware and software afterward. This remote supervisory system was established based on the Browser-Server（B/S） Mode Developed with Microsoft VB.NET and ASP.NET technical criterion. The hardware was composed of 3 parts： a PC computer that can access to internet, a RS-485 bus cable as a middle bridge connecting both the PC and digital sensors, all of which formed a field monitoring system for greenhouse environment information. The result showed not only the real-time greenhouse environment data could be acquired and browsed in a remote site, but system parameters could be edited and set up through accessing to the internet. In addition, this system was not only available to realize data acquisition and management for a greenhouse, but could be easily adopted to other agricultural field as also from other remote places.
