齐 齐 哈 尔 大 学 毕业设计（论文） 题 目 基于Zigbee的智能温室数据采集系统 学 院 通信与电子工程学院 专业班级 物联网工程112班 学生姓名 指导教师 成 绩 2015年 月 日 is a hot field in concern, was named one of the three future high-tech industries. Zigbee technology is a short distance, low rate, low power consumption, low cost and high reliability of wireless communication technology, mainly suitable for automatic control and remote control, you can embed a variety of devices, very suitable for the task as organization of WSN, these characteristics make the technology for low power consumption, low cost and low rate wireless communication market vacancy, its application prospect is very optimistic. This is the theoretical analysis of Zigbee technology, analyzes the networking mode of Zigbee technology, combining the domestic existing sensor technology, wireless sensor network system for greenhouse environment data acquisition scheme is proposed. Build a WSN through Zigbee wireless communication technology. The system consists of sensor nodes, routing node, central node and PC monitoring platform. The system uses a tree topology, the temperature of the sensor nodes join the network, the light intensity and rainfall data collection and analysis, applied to the environment on agricultural greenhouse monitoring and control.
