Design And Implementation Of Intelligent Greenhouse Monitoring System Based On ZigBee Technology

China as an great agricultural country, with the continuous development and expansion of the agricultural scale,and the increase of labor cost as well as the complexity of the cable laying the traditional cultivation method is no longer adapt to the development of The Times.In recent years, the Internet of Things technology is underway, including the Internet of agriculture.That is use the Internet of things system of various sensors in the greenhouse control system, detect the physical indexes of temperature and humidity as well as illumination in the environment, then real-time display them through the variety of instruments and meters or as a parameter depending on the automatic control involved in the automatic control, to ensure the crops have a good and suitable growth environment.This paper combine zigbee sensor network with Ethernet, using zigbee network complete environmental data collection in the greenhouse environment, then convert the data to Ethernet data through the gateway, allows the user to use mobile device through the Ethernet to check the environmental data in greenhouse, at the same time, users can make remote control for environmental control equipment in greenhouse through this system.In this paper, first has carried on the overall design according to the requirements of the system implementation,divide the whole system into several modules according to the function, and then make the detailed description to the design of each module.Because of this paper is mainly realize use zigbee module to achieve the data acquisition and upload in greenhouse,the two chapters after describe the zigbee management module and the design and implementation of zigbee terminal module.The terminal module mainly realize the data collection and upload,at the same time conduct the energy saving design and alarm design for the terminal module.Management module is mainly to complete collect upload data of the terminal module and transpond the data between zigbee and serial,and then design white list management, AP state of isolation and state identification function for the Management module.For each data collection process, use the terminal module as collect probe in greenhouses through the temperature,humidity and illumination sensor to collect environmental data and then transmit the data to management module through the zigbee network,management module via a serial port connection gateway and send the environmental data which collect by the white list’s terminal to the upper module through a serial port,finally the data realized transpond from serial port to Ethernet by the gateway and then sent to the server.At the end of this paper, firstly make unit testing for each functional of the zigbee module and then test the whole system, the test results show that the system achieve the desired effect.
