Modern Agriculture Planting And Agriculture Products Information Management System Design

By controling the optimal growth conditons of crops invegetable for modern agriculture.The purpose is to maximize productivity,reduce labor intensity,scentific planting,ensure the security. That has changed the traditional outdoor planting with experience and weather. Through adopt RFID electronic tag technology to improve the information management of agriculture products,realize a whole process of products safety management mechanism from farm to table.Use IOT technology has important pratical significance to realize modern agriculture planting and agricultural information management.The IOT technology is based on Internet technology,is extending goods and goods between client.It is defined as through radio frequency identification(RFID),infrared sensors,global position,laser scanner sensor devices,accord to the agreed protocol,which Ant items can connect and commuincate with IOT,to achieve a network technology of intelligent identification,monitoring,tracking and managing.Because of automatic monitoring and food traceability in modern agriculture and circulation,ZigBee and RFID provides an effective solution to solve this problem.ZigBee is a short-range,low-power,low-data-rate,low-cost,low-complexity wireless network technology.ZigBee uses all the advantages of strong wireless physical layer of the IEEE802.15.4:energy saving,low cost,adds logical network,network security and application layer. Modern agriculture uses sensors and ZigBee network,which will translate into the network,intelligence,automation and remote control of the production mode. The data for monitoring is not huge,such as:temperature&humidity,light and so on.In modern agricultural production process,the node is vey huge,without human operation.The above characteristics of ZigBee provides a good solution to sovle remote automatic monitoring in agricultural production.In recent years,radio frequency identification(RFID)technology has been promoted and developed by China.RFID technology,also known as wireless identification technology or electronic tags. Through radio signal to identify a specifin target,and to read and write data without the need to make contact with a specific target.In recent years,the RFID has a wide applications,such as:access control system,libraries,food safety,traceability and so on.RFID is uesd in food safety management,and is accompanied by an electronic tag for the food every stage from form to table,this information is released to internet.When consumer shopping,the information of food can be found by electronic tag and truly traceable. This system appliy to agricultural production and agricultural safety management,which is divided into three main parts,the first to use sensors to perform the wireless data acquisition,the second to remote intelligent control,the third to use RFID technology to achieve food traceability.The operator install a multi-parameter sensor,such as temperature&humidity and light and so on,each sensor use ZigBee wireless module to transmite real-time information to the monitoring network.Gateway is responsible for receiving data from the wireless sensor node,and to storage data,proceesing,display and management,and display to the users with a intuitive charts and text prompts.and can provide alarm information.The system not only wireless monitor planting enviroment parameters,but also analysis paramters based on intelligent,and timely control greenhouse fan,sprinkler irrigation and other equipment,in order to achieve the agricultural cultivation intelligent monitoring. What is more,can use ultrasonic sensor to measure distance and use infrare sensor to alarm when someone trespassing into the canopy. The technology not only will improve productivity,energy saving and enviroment protection,but also reduce the waste of resource.When crop mature for the picking,paste electronic label and entry its meassage,and entry relatead message again in the process circulation,and to publish on the internet. In this way,consumers can query information in the electronic tags from production to distribution,and traceable to ensure food safety.This paper research wireless sensor data acquisition,remote intelligent monitoring and RFID technology.The main contents and conclusions are as follows:1.Design a monitoring system based on ZigBee CC2530greenhouse enviroment.The ZigBee node translate information from sensor to the coordinator through ZigBee network,the coordinator connect to PC through RS232interface and display information and save it to the database.2.This paper develop PC software and display the information in the electronic label based on existing MF-30W RFID,and read and modify information in the electronic label through PC software,and can store this message into database.3.The selection and design of the system hardware.To consider the requirement of low power consumption and low data transmission rate,so use TI’s ZigBee chip and conduct hardware design under this way. Including sensor selection and peripheral circuit components selection.This system uses four types of sensors:temperature&humidity sensors,light sensors,ultrasonic sensors and infrared sensors.This system uses a5V relay switch perform output.4.Network mode.Using Z-Stack protocol stack and IAR as software development platform,using C51language to develop each node application,so to complete data collection,transmission,control.And format different network structures according to the coordinator,router,terminal nodes,star,tree and a-mesh type network.This application uses a tree network structure as a wireless network structure.5.Host computer program design.The system uses two modes to remotely monitor lower machine:C/S mode and B/S mode.C/S mode:use basic2005development envirorment and Sql-server database to develop software.and to achieve real-time remote monitoring,data display,data storage and curve tracing.B/S mode:use PHP language and Sql-server database to realize remote monitor of enviroment grrenhouse,data display,and easy to browse.6.The whole system has been carried simulation test and analysised the summaried acquisition in the Yangtze university main building process control laboratory and corridor.The experiment results show that wireless sensor network work stable,monitoring system operate well,the control effect is good.
