Research On Intelligent Measurement And Control System For Greenhouse Based On The Internet Of Things

With the continuous improvement of agricultural informatization level, The intelligent measuring and control system of China's greenhouse have achieved great development in the aspect of technology and scale but compared with developed countries, there is still a big gap in the field of greenhouse intelligent control, especially in the control of the stability of production, supporting facilities modernization and industrialization degree. Meanwhile, because the introduction price of the foreign control system is high the operation is complicated, the system is not suitable for our climate characteristics and some other issues, greenhouse intelligent control system has been the bottleneck of China's greenhouse development. In view of this, I proposed the research project of intelligent measurement and control system for greenhouse based on the internet of things in order to achieve greenhouse intelligent control from low-cost, simple operation and other aspects.This paper first introduced the related research and development technology used in greenhouse intelligent control system of greenhouse, analyzed the principles and objectives to achieve starting from the overall system solution and gave the overall framework of the system. And then I introduced the system development thought and implement in accordance with the order of the perception of internet of things, the transmission of internet of things and the intelligent control of internet of things. Software design I introduced the PC program developed for needs of the hardware acquisition system to achieve the following functions: automatic data collection, cellphone APP, intelligent control by cellphone, PCside Web page, the data collection of greenhouse display.The intelligent measuring and control system uses a hierarchical design to divide the system into three parts, including the perception of internet of things, the transmission of internet of things and the intelligent control of internet of things. Each part is built by different modules. The perception of internet of things includes the sensors, information sensing module, signal conversion board, the information processing and control module to complete data collection. The transmission of internet of things is a GPRS module to transfer collected data to the server. The intelligent control of internet of things includes a mobile phone APP, control module, devices and the control terminal to achieve greenhouse intelligent by cellphone.And i developed the PC program based on VC ++ in support of existing hardware devices to complete the automatic data collection and verification of greenhouse,and then store the data in the Mysql. I developed the mobile App and PC application to let the farmers view the data collection of greenhouse real time and control greenhouse intelligently.The research on intelligent measurement and control system for greenhouse based on the internet of things improves the accuracy of information collection in modern agriculture and the efficiency reliability of transmission, makes the control more efficiently and effective, keep the system more stable. It has a high economic efficiency, broad market prospects and promotional value.
