Tea Garden Environment Real-time Monitoring And Warning System For Frost Prevention Based On GIS

Tea is one of the major cash crops in the farming. In China, tea plantation area is wide,output is large, but the unit of production is not high. Due to various reasons, the productionof tea decrease, the quality of tea is poor, and a direct impact on the economic benefits of teacultivation. Frost damage resulting economic losses caused by late spring is relatively large,so the tea garden environment real-time monitoring and prediction of frost damage occursearly warning in a timely manner, it can reduce the economic losses caused by frost damage,improve the yield and quality of tea.Using ZigBeeSZ06ZigBeeSZ02module and the temperature and humidity sensorsbuild tea plantations temperature and humidity monitoring wireless sensor networks,real-time monitoring of plantations across the temperature and humidity changes.UsingMapinfo and its secondary development language Mapbasic and serial communicationinterface, develop tea garden environment real-time monitoring and Warning system forFrost Prevention to real-time monitoring of the tea garden environment, and timely warningbefore freezing injury. The main work and results of the study are as follows:(1) Design the Overall structure of tea garden environment real-time monitoring andWarning system for Frost Prevention. Design the overall structure and function of the system,and the system is divided into three parts of the network of data acquisition, signaltransmission, information processing center. The tea plantations data collection andtransmission network is build. Using ZigBee technology as the wireless data transmission,each acquisition node of the temperature and humidity sensor, through the collection ofnodes at the ZigBee module is connected to the central node ZigBee module for datatransmission, for each node in tea plantations, temperature and humidity data is transmittedto the central node, and finally through The serial communication interface to transfer data tothe data processing center. By constructing the output collection network, the tea gardenacquisition node at the temperature and humidity information is transmitted to the dataprocessing center for tea garden management, data processing and warning information release, provided the original data.(2) Develop tea garden environment real-time monitoring and Warning system toprevent frost. In this paper, Use Mapinfo secondary development of language Mapbasicdeveloping tea garden environment real-time monitoring and Warning system for FrostPrevention, combined with the serial interface communication technology, the entire teagarden each monitoring node temperature and humidity, entered into the system, and dataprocessing. Tea garden environment real-time monitoring and Warning system for FrostPrevention able to real-time the tea plantations temperature and humidity monitoring criteriaquery, statistics, decision-making, real-time display, history query capabilities, real-timemonitoring through the tea plantations of environmental information processing, teaenvironmental information, and frost warning.(3) Develop data acquisition and processing system based on mobile platform. Mobileplatform data acquisition and processing system to the development of the tea gardenenvironment real-time monitoring and frost warning system auxiliary. Using ARM JZ2440development board, running the program of Qt and serial communication program in theLinux operating system, real-time displaying of the monitoring node temperature andhumidity in the tea garden. Mobile platform for data acquisition and processing systemdeveloped in this paper, to make up for the tea garden environment real-time monitoring andlack of frost warning system, to facilitate the realization of the real-time display of the teaplantations environmental information.(4) Test tea garden environment real-time monitoring and Warning system for FrostPrevention, data acquisition and processing system based on mobile platform, and get theperformance of the system parameters. The tests showed that the tea garden environment ofthe PC real-time monitoring and frost warning system, can real-time monitoring of theenvironment of the tea garden, tea environmental information real-time monitoring anddisplay, real-time query, historical statistics, early warning and decision-making, real-timedisplay, history query and other functions; mobile platform to run data processing systembased on ARM JZ2440development board can be displayed in real time by moving thetemperature of the tea plantations acquisition node, wireless data reception and transmission.The tea garden environment for real-time monitoring and frost warning systems thatdeveloped in this paper meet the requirements of the monitoring and early warning. The dataprocessing system of the mobile platform can compensate for the tea plantation environmentreal-time monitoring and the frost warning systems rely on the PC insufficient on tea plantations temperature information is displayed in real time, to meet the designrequirements.The innovation of this paper is to use Mapinfo secondary development languageMapbasic to develop tea garden environment for real-time monitoring and frost warningsystem, which is able to real-time information display, real-time query, historical statistics,decision-making, real-time display, history of queries and other functions.Design anddevelop data acquisition and processing system based on the ARM9series JZ2440mobileplatform, mobile terminal in real time in the field for various monitoring temperature andhumidity data storage and real-time display to auxiliary tea garden environment real-timemonitoring and antifreeze early warning systems. The study’s significance lies in thecombination of GIS and sensor network applications, the tea garden environment forreal-time monitoring and frost warning by tea environmental information and tea plantationsspatial information combined to precise management of the tea plantations, real-timemonitoring of the environment for the growth of the tea plant, reduce the impact of naturaldisasters, and improve the yield and quality of tea, to achieve the purpose of improvingeconomic efficiency.
