Research And Design Of Intelligent Monitoring System Of Agricultural Greenhouse

With the continuous development of the Internet of things technology,greenhouse is become an important form of modern agriculture,and its monitoring and control technology have been improved at the same time.In order to improve production efficiency and increase production of greenhouse cultivation,it is need to rely on advanced automation technology and equipment because of that traditional wired control and manual operation have been unable to meet the demand of the market.The environment of crops in greenhouse in real-time can be collected and controlled for ensuring the best growing environment of plants.Internet technology is widely used in agricultural greenhouse,and Zig Bee technology have greatly promoted the Internet of things technology applied in intelligent greenhouse environment monitoring,and it will has a broad space for development.Based on the efficient agricultural production way in the greenhouse,agricultural greenhouse monitoring system was developed by the sensor technology,Internet technology,automatic control technology and measurement and control technology in this paper,and it could realized the refinement of agriculture planting for the characteristics of remote monitoring and control,and it has the very high practical value.(1)The development present situation of intelligent greenhouse monitoring system at home and abroad was investigated and analyzed,and then this paper determined the overall design.How to chose the server hardware,embedded operating system and wireless communication technology were discussed in this paper.And Zig Bee wireless network technology,IEEE802.15.2 standard and Zig Bee technology architecture were introduced in detail.(2)This paper introduced the software development environment build of monitoringsystem of greenhouse and the process of Zig Bee ad-hoc networking.The main function of data collectionwas to collect temperature,humidity,light,carbon dioxide and other data within the greenhouse using development board STM32F103ZE76,then transmitted to the server via Zig Bee CC2530.Furthermore,greenhouse control was used to remote control pumps,humidifiers,lighting and ventilation inside the greenhouse.The main function of monitoring system server of greenhouse was data aggregation,data packing and data transfer.Embedded server in the paper adopted Samsung Cortex-A9 as its main control chip and transplanting embedded Linux operating system.Moreover,PC web client and cell phone client were developed to monitor greenhouse environment in real-time.(3)Joint debugging of the hardware and software was done in the paper,and the whole performance of system was also proposed in the paper.The test results indicated that monitoring system of greenhouse proposed in this paper conforms to anticipated requirements of the design.
