Design And Realization Of Remote Greenhouse Monitoring System Based On ZigBee And Web Technology

Greenhouse is an important application of agricultural development in China facilities,there are already some professional construction of greenhouse enterprises.There are many existing research and design,but the application and the actual implementation are still relatively few,there are design errors,the greenhouse layout is cumbersome,the cost is too high can not be applied,the key issues lack a clear description of how to carry out intelligent remote management and control of the greenhouse,Poor portability and other issues.At present,the intelligent control of greenhouse is not mature,the cost is high and the transplant is poor.The purpose of this design is to build a low cost,easy to build,easy to operate,strong portability of greenhouse remote monitoring system.This design has carried on the analysis to the greenhouse monitoring program in the past,and points out its advantages and disadvantages,the existing monitoring scheme is improved,realizing the remote control,and the operation cost is low,the user can accept.In the process of design and implementation of the need to pay attention to the problems and key parts,are specified in the text.Based on ZigBee and Web technology,this paper studies how to collect data of various environmental parameters needed for greenhouse crops and display and control them through B/S(browser/server)structure.Compared with commonly used C/S(client/server)structure,system maintenance,user access are more convenient.Users can connect to the Internet as long as the equipment,whether computer or mobile phone,no matter where in the country,through the browser to view the greenhouse environment parameters,and the ability to remotely manually or automatically control the scene of the implementation of the device,the real realization of the greenhouse Of the remote monitoring,so that greenhouse monitoring to the wisdom of agriculture in the direction of development.This design abandons the ZigBee terminal node mount execution device design scheme,only uses the terminal node to collect the greenhouse environmental data,the greenhouse site execution devices are connected with the ZigBee coordinator to save energy,to save energy,reduce greenhouse wiring,improve system portability.In the remote server(also known as the cloud server),use C#language build server receiver software,The data sent by the GPRS module in the greenhouse is imported into the Sq1Server database,Using ASP.NET technology to design a three-tier architecture for easy maintenance Greenhouse monitoring Web site,and use a variety of third-party plugins to optimize the display page,simplify user operations,improve Web page access comfort.In addition to the on-off control of the greenhouse environment,in order to control greenhouse soil moisture simulation as an example,the use of intelligent automatic control of greenhouse soil humidity fuzzy control algorithm to achieve accurate irrigation and water conservation purposes.After the theoretical analysis and design of the whole system,the detailed experiments are carried out to verify the results.The experiments show that the system is reasonable in design,stable and reliable.
