密闭式植物工厂的嵌入网络式环境监控系统

Web-based environmental control system for closed plant factories

21世纪对蔬菜、林木、药草、香料等各类种苗或植物的大量需求将推动完全使用人工光源的密闭式植物工厂的大力发展。为了配合密闭式植物工厂内的适度环境控制和能源收支核算的研究需要,基于关系数据库MS SQL Server 2000和面向对象的程序设计语言Visual Basic 6.0开发了通用型嵌入网络式环境监控系统软件。用户可根据实际生产需要选择适当的控制策略和控制目标,也可调整控制参数来增减或改善执行机构的运行。植物工厂内所有控制参数和实时监测的数据和图像都可以动态地进行WEB发布,用户界面友好并实施各级安全自动管理。经过近两年的实际运行,该环境监控系统软件有效地实现了人工光型密闭式植物工厂内的嵌入网络式动态环境监控和电能消耗自动计量。

Closed plant factories using artificial lighting will be extended commercially because of the large-scale requirements of the transplants or plant such as vegetables, forest tree, medicinal herb, and spice plant in the 21^st century. In order to research the optimal environmental control and electronic consumption accounting in the closed plant factories, a web-based environmental control system was developed using MS SQL Server 2000 and Visual Basic 6.0. The control strategy and control targets can be adjusted by end-user in local or remote areas via any browsers and the controlled equipment can be adjusted or improved easily with different levels of system security. All control variables and measured environmental data and plant images are monitored dynamically using web-server-embedded technology. The environmental control and electric consumption accounting were carried out in a pilot-type closed plant factory operated for two years in China Agricultural University.
