Design And Implementation Of Digital Greenhouses Cloud System Based On Hadoop

With the rapid development of China’s agricultural greenhouses, more and more technology gradually applied to the agricultural greenhouses, more intelligent greenhouses and digital greenhouses, appeared in people’s field of vision. However, there are differences and innovation points between digital greenhouses. Digital greenhouse can realize the environment needed for the plant in the parameters such as temperature, humidity, illumination and so on almost all of the indoor environment parameters for automatic control, Implement an intelligent monitoring system.Due to the size of digital greenhouse develop rapidly, large sensor system, task detection and control system urgently needs to a stronger performance, function more comprehensive system for management. Considering the development of distributed technology in recent years, if the technology can be applied to digital greenhouse of task management, regularly will greatly facilitate the management of these tasks, the number of tasks can be managed will also greatly increase.In this paper, using the Hadoop distributed file system, and components, including ZooKeeper etc, to build distributed task management platform. Using SQL database technology and the socket server programming technology and Java web technology to achieve a user can be remotely controlled by computer digital sensors in greenhouses, real-time information within the sensor real time back to the greenhouses and displayed to the user of the system. In this system, users can also set tasks regularly, within the system can monitor greenhouse environment parameter, once the parameters exceed expectations set limit, the system will automatically work out mission control greenhouse sensor to make a balance.
