Research On The Control System Of Agricultural Greenhouse Based On Cloud Management

With the rapid development of China's modernization process,the traditional mode of agricultural communication and monitoring can not meet the growing demand of China.Traditional agricultural greenhouses more use of the site wiring,resulting in the field line complex,but also to the construction and maintenance of the difficulties brought about.In addition,it will be stored in the local computer for data collected in the field,which not only makes the data security threats of the location of the query time bound.In view of the above problems,put forward the solution of the overall design of the agricultural greenhouse control system based on cloud management.The whole system consists of two parts: the bottom data collection and the data processing section of the cloud.Data acquisition using ZigBee wireless communications,cloud computing consists of two parts: the cloud part and the client part.The cloud is a variety of hardware and software,computing,storage,services,network software and hardware resource pool.Greenhouse users or managers only have access to the Internet terminal equipment,environmental parameters of greenhouse can access,such as real-time display and historical curve.In the monitoring part,for the completion of the node of the wireless acquisition and transmission parts of the data(including the coordinator node,terminal node)programming,simultaneously with the VB software in the local monitoring part of the preparation of PC monitor screen.Local data is uploaded to the cloud database through the Web code in order to achieve Internet access in the data in the form of a web page.The result shows that: the wireless sensor node parameter acquisition work is normal,ZigBee wireless sensor network coordinator and terminal node network normal,data can be transferred to the cloud computing platform.People who are not at the scene by the authorized person only need a terminal by the Internet can access the cloud platform data.It is shown that the system is stable and practical,consistent with the requirements of greenhouse management.
