Application Of Wireless Sensor Network In Agriculture Greenhouse

Modern agriculture and informatization are closely connected. To realize the agricultural modernization, we need to actively take advantage of modern technological achievement to speed up the development of agricultural informatization. In this process mature information technology can be gradually brought into agricultural production practice. In order to better solve agriculture greenhouse data acquisition problem, it is one of the best ways to apply wireless sensor network (WSN) to information detection of agricultural shelter. Through the application of wireless sensor network, we can effectively reduce the human consumption and crop environment influence so as to gain accurate crop environment and crop information of agricultural shelter. Wireless sensor network (WSN) is a kind of no center of whole distribution system node. Through random launch way, many sensor nodes are concentrated in the supervisory control area. The sensor node integrates sensors, data processing unit, communication module with energy units, through wireless channels,connected into a self-organizing network system.The dissertation adopts collecting atmospheric temperature and air humidity sensor, combining the characteristics of WSN, from the Angle of low power consumption, to monitor the vegetables canopy temperature and humidity factors, and designs vegetables shelter information acquisition and monitoring of wireless sensor network. This system consists of perception nodes, gathering nodes, the monitoring center based on WEB server, etc. Numerous perception nodes acquisition agricultural shelter crops'growth environment information and send messages to converge node by gathering Zigbee network nodes through the Internet real-time uploaded to the monitoring center of the database. Via system analysis and processing,these data can help management personnel manage vegetables greenhouse. Practically it shows that the application of wireless sensor network technology in agricultural greenhouse, not only promotes crop yields, but also provides new technology power to the development of modern agriculture through the wireless sensor networks which acquisition crops'growth environment.
