温室环境因子无线自适应系统

Wireless Adaptive Control System for the Enviremental Factors in the Greenhouse

现代温室的环境因子(包括温度、湿度等环境参数)测控系统中,传统的有线通信受到监测环境、数据传输距离和成本的制约,限制了温室进一步大规模的发展.因此,本文通过建立无线传感器网络,实现测控环境中不同区域的温湿度信息无线实时采集与监测;同时根据植物生长环境需求,通过无线传感器网络中的控制节点控制温室中的机电设备,启动或者关闭相应的执行器(天窗、湿帘、遮阳帘、风机等),实现对温室环境因子的无线自适应控制.因此,设计温室环境因子的无线自适应控制系统是解决现代农业温室测控领域中因有线通信而受限的有效途径之一.

In modem agriculture acquisition systems for the enviremental factors（temperature, humidity and so on）, traditional wired communications are subject to the constraints of environment, costs, and data transmission distances, etc. In this thesis, we establish a wireless sensor networks to realize real-time temperature and humidity data acquisition and monitoring from different areas in a greenhouse with wireless sensor nodes; Simultaneously, we control the mechanical and electrical equipment by the control node in the wireless sensor networks to turn on or turn off the equipment （such as skylight, wet curtain, sunshade, fan, etc）, according to the optimal growth conditions which are required by the crops in the greenhouses.Therefore, design a wireless adaptive system for the enviremental factors is one of the effective ways to solve the problems which occurred in the wired communications.
