Design Of Orchard Pest Information Monitoring System Based On Lot Technology

In order to protect the fruit trees and-obtain better yield,it is a very important measure to monitor the number of pests in the orchard accurately and timely.But many orchard area is bigger,wanting to obtain these relevant data information in the orchard,we need not only a lot of manpower and material force,and the real time also is difficult to get assurance.In view of the problems of early warning of pests and diseases in orchard and the lack of online monitoring methods,this article develops insect infestation surveillance sensors for disease transmission to realize the local area orchard pest information real-time monitoring based on ZigBee and GPRS technology.The research contents of this paper are as follows:Firstly,completed the design of data acquisition module.Acquisition module uses high voltage power grid down insects,and the number of pests is counted by photoelectric sensor.Combining with GPS module,acquisition module finally use Keil uVision for microcontroller programming to integrate the photoelectric sensor and GPS module of latitude and longitude information,and the data is periodically sent to the ZigBee terminal node via a serial port.Secondly,completed the design of ZigBee terminal node and gateway node.ZigBee coordinator in the terminal nodes and gateway nodes choose CC2530 chip of TI company,studying the ZigBee protocol and its protocol stack,and on this basis,we use the IAR Embedded programming to complete the coordinator node network establishment and ZigBee terminal nodes to join the design.At the same time,we configure the corresponding parameters of the coordinator node and GPRS module in the gateway,and conduct serial communication.Eventually,the gateway realizes ZigBee signal to the GPRS signal conversion,and signal is sent to the cloud platform via GPRS module.Thirdly,completed the design of the remote monitoring center.The design of the remote monitoring center including the remote data center software design and the software design,it uses SQL Server,Socket,and IIS Web Service technology to receive,storage and distribution the data.Meanwhile,it uses the Java language and Baidu map Android SDK for secondary development to display the monitoring data based on GIS display and user processing.Finally,test the propagation characteristics of wireless sensor network in the orchard environment.According to the characteristics of the environment of the peach garden,the test will measure the receiving signal strength and packet loss rate at different heights and at different distance points along a row of peach trees.We study different heights in the wireless signal attenuation,calculated the node signal coverage,and the regression analysis of experimental data in MATLAB.Plant diseases and insect pests information monitoring system design,this paper through constructing the organization information network transmission,spatial geographic information,mobile phone and computer network real-time monitor orchards of plant diseases and insect pests in the area of information distribution,reasonable threshold for orchard mechanization of plant diseases and insect pests prevention and control;Distribution according to the real-time monitoring of plant diseases and insect pests,late can combine the micro climate information inside the orchard,to early warning of orchard pests spread trend,generate orchard mechanization pest management decision-making,scientific guiding chemical pesticide precision spraying the target areas.
