为了解决当前温室监测系统存在的布线复杂、节点功耗大、部署不灵活、管理不便等问题，设计了一种基于无线传感器网络的温室环境信息监测系统。以CC2430为核心开发无线传感器节点，完成温室环境因子实时监测；采用ZigBee技术实现无线传感器网络自组网和监测数据自动汇聚；基于ARM9微处理器S3C2410A和WinCE5.0构建网关节点，采用嵌入式数据库管理模式实现了传感器节点管理、环境数据管理和预警等功能。初步试验表明系统具有功耗低、组网灵活、可扩展性强、人机界面友好等优点，能较好地满足温室环境监测的应用需求。

System Based on Wireless Sensor Networks

Based on wireless sensor networks, a greenhouse environment monitoring system was designed to deal with problems in current greenhouse monitoring system, such as complicated cabling, high energy consumption, limited transmission distance, and inflexible deployment. With SoC of CC2430 and ZigBee protocol, environment information was collected, self-organized networks were realized and aggregated monitoring data was collected by the wireless sensor node. Gateway hardware platform was structured based on the S3C2410A microprocessor, and WinCE5.0 operating system was chosen as software platform. A gateway management system was developed on embedded database for sensor node administration, data processing, and early warning of weather disaster. Preliminary experimentations showed that the system met the application requirements of greenhouse monitoring system excellently, and had the advantages of low power consumption, inexpensiveness, flexibility, extensibility, and friendly human-machine interface.
