摘要
针对连栋温室环境监测系统布线困难、监测低效、部署不灵活等问题,设计了一种基于无线传感器网络的低功耗监测系统。以CC2530为核心构建传感器节点,以Zig Bee技术构建树状无线传感器网络覆盖整个温室范围,搭配现场PC构建现场自动化监测系统,24 h监测环境变化;在传感器节点中进行硬件和软件的低功耗优化设计,降低建造和维护成本,添加时间同步管理和电源管理,增加系统可靠性。初步试验表明:系统能以较低的功耗(提高96.3%)实现数据的准确采集,符合科研和精细化生产的应用要求。
Aiming at problems in greenhouse monitoring system,such as difficult wiring,inefficient monitoring and inflexible arrangement,design a low power consumption environment monitoring system based on wireless sensor networks（ WSNs）. This system constructs sensor node using CC2530 as core,builds tree-like WSNs with Zig Bee technology to cover all the greenhouses fields,then coordinates a local PC server to build scene auto-monitoring system to monitor environment change continuously in 24 h. In sensor node,low power consumption optimal design of software and hardware are carried out to reduce building and maintenance cost,and time synchrony management and power management are added,increase system reliability. Preliminary experiment shows that,accurate acquisition of data can be realized with lower power consumption（ 96 % energy reduction ratio）,and meet requirement of science research and fine production.
