| The rapid development of mobile Internet technology provides technical support for automation and intelligentization of agriculture.Intelligent agriculture based on mobile Internet technology is the new direction of agricultural development in China.This paper,based on the application of mobile Internet technology in intelligent agriculture,designed a remote intelligent monitoring system for agricultural greenhouse in view of the problems and shortcomings of our agricultural greenhouse monitoring and control system.The whole system is mainly composed of three parts: ZigBee wireless sensor monitoring module,ZigBee coordinator,+GPRS wireless gateway communication module and monitoring client.The ZigBee wireless sensor monitoring module converges the collected greenhouse environment information through the ZigBee network to the ZigBee coordinator +GPRS wireless gateway communication module.The gateway communication module uses the GPRS network to link the data with the mobile or the Unicom base station,and then sends the environmental information data to the remote Web server through these base stations.The data i s analyzed and stored by the Web server.The user can observe the real-time environmental data in the greenhouse through the browser on the PC or APP and query the change curve of the greenhouse information according to the historical record.The system su pports the user's real-time query and monitoring of the greenhouse environment information.It also supports remote control of the greenhouse equipment according to the growth stage of the crop and the environmental parameters of the greenhouse.In this paper,based on the analysis of the development trend of greenhouse technology at home and abroad,the overall demand of the system is put forward,and the overall design framework and key technology of the system are given in combination with the overall design requirements,and the ZigBee technology is emphatically introduced.In the hardware design,the selection of each node sensor module is completed,and the related hardware modules are elaborated and designed in detail.In the software design,the software function design and debugging of the system related hardware are completed,including the building of ZigBee wireless sensor network and the transmission of ZigBee wireless data..The ZigBee wireless sensor network and the GPRS module,the GPRS modul e and the Web server,the Web server and the Android terminal are realized,and the data communication process between the three is elaborated in detail.Then completed the Web server function design,Web server as the carrier of the system data,data proc essing,analysis and preservation.The design of Android client software is completed.The whole Android client implements real-time data monitoring,real-time monitoring,remote control of equipment,historical record query,alarm statistics and so on.Finally,the system function test is completed,including the networking test of ZigBee wireless sensor network,the acquisition and testing of sensing data and the testing of remote monitoring function of the system.The test results show that the design realizes the expected function,and the system works stably and reliably. |
