The Research Of Intelligent Agricultural Based On Wireless Network Sensor

With the rapid development of electronic information industry, information technology has penetrated into various traditional industries, such as agriculture and information technology combined with traditional resource utilization can greatly improve the efficiency of agriculture and labor. Wireless sensor networks(Wireless Sensor Network, WSN) is a popular application in recent years, more and more distributed sensor networks, it is a great prospect micro network systems. By the end of its sensor tip is to obtain information on the various monitoring points and real-time feedback to the system control center to monitor nodes to achieve various environmental data to detect changes in object detection and tracking. Development to the present, wireless sensor networks have been widely used in modern military systems, intelligent transportation, environmental data monitoring, health healthcare, smart home and other fields.The first topic of intelligent information for agricultural background and significance of the study, also introduced the application status of agriculture of things, domestic and foreign intelligence information for agricultural development situation and trends; at home and abroad for the agricultural problems in the field of information and briefly describes the advantages of intelligent agricultural information.Secondly, this paper describes the design of some of the modules need to use: data acquisition module, ZigBee wireless transmission module, GPRS remote wireless transmission module, process control module, the energy module and PC terminals. Wherein the data acquisition module using various types of high-precision sensors, and the acquired analog signal into a digital signal that can be processed to identify the chip. Communications design issues, short-range wireless transmission using the ZigBee communication technology, remote communication using GPRS / GSM communication network. Process control subjects using ATmega32 microcontroller module for processing information for the relays and control operations, such as memory chips and circuit boards produced. Energy supply module utilizes solar panels and battery combination of programs, for power and endurance of the entire system has a great protection. Terminal with a time limit may be subject to geographical app Android-based phone systems and computer software for the above acquisition and display PC GPRS / GSM transmission network through over the information, and can make a scientific environmental data based on information received from the field judge, issued a directive corresponding control operation. Subject to performance requirements applied to wireless sensor networks, ZigBee technology, GPRS technology and other key technologies, parameters and problems performed a detailed introduction and a brief introduction to the advantages and disadvantages of these technologies.Finally, after each module to communicate with the above system independent testing is complete, the module integration, complete information for intelligent control scheme for agriculture based on wireless sensor networks. Through communication experiment proves successful enforceability and effectiveness programs.
