摘　　要：针对上海地区广泛使用的连栋塑料温室,提出了一种温室内环境智能控制方案。采用主从式结构,分为远程服务器和现场智能测控站。其中远程服务器负责温室集群远程管理,现场测控站负责温室环境数据处理,实施控制决策,提供人机交互;为了实现多任务并发,测控站采用Linux操作系统。测控软件采用Qt平台开发,具有高可扩展性和移植性,并包括了基于轻量级嵌入式数据库SQLite的专家系统。将华东地区典型作物生长和环境参数的数值关系引入温室控制决策中,提高环境控制效率,有效减少温室能耗。通过某示范温室的现场测试,表明系统稳定可靠,控制效果明显。An intelligent greenhouse environment control scheme is proposed for multi-span plastic greenhouses in Shanghai district. In the scheme, the hardware system is composed of a remote PC server, intelligent measurement and control station （ICS }, which implements environmental data measurement, control decision and human-machine interaction. Therefore, Linux was adopted as the operation platform for ICS due to its multi-task function. The ICS was developed on the Qt/Embedded platform to ensure high modularization and portability. Intelligence of the greenhouses is realized by an agricultural expert database based on SQLite. The database can provide expert control scheme based on the relationship between greenhouse environmental parameters and crop growth requirements in East China. The whole plastic greenhouse environment control system is running stably and efficiently in the sample greenhouse.
