Some Key Technologies Used In Wireless Sensor Networks In Agriculture Research And Application

Along with China’s agricultural information and intelligence is gradually accelerating pace, agricultural applications of wireless sensor networks based on agriculture in the networking industry has been an unprecedented development, agricultural wireless sensor network technology as the core of the wisdom of agriculture is to enhance the pace of agricultural development strategy to make an important contribution to things related to agriculture intelligent system also plays an important role. Based on the characteristics of the Northeast ginseng industry in this industry as the research object, the relative independence between the lack of overall monitoring device protection, complicated wiring, power measurement and other issues between its regulatory and other aspects of the existence of planting equipment for centralized combing and put forward reasonable solutions.To solve the above problem, this paper has researched the following area:(1) Image-based remote collection of embedded LinuxRemote video monitoring system based on agriculture 4G includes hardware design and software design and testing problems encountered and solutions. For farmland signal is weak, difficult terrain and other conditions, by networking technology 4g camera and remote client organic combination, allowing users through the Internet will be able to observations from farmland at home.(2)Transmission signal strength between node researchIn zigbee, using two WeBee modules communicate with each other, a module for launch another module are received, then the measured packet error rate, RSSI value and the number of the received packet data, etc., in order to analyze the measured signal strength. While the construction of different models for different environments different obstacles field measurements and statistics the impact of different objects on the signal strength.(3) battery detectionIn order to further improve the system, response systems in practical applications has been improved and strengthened, such as for solar battery problem, add a power display function, Zigbee wireless sensor network technology used in the production of battery charge and discharge process parameter monitoring, the realization of power display, allowing users to keep abreast of power nodes and handle;(4)The establishment of ginseng Remote Monitoring SystemTo solve the above problem, and ginseng designed a remote monitoring system, so that the above three problems with this system as the basis of better reflected, while the system is equipped with light sensors, temperature and humidity sensors and other external devices to form wireless sensor networks, so that it can grow ginseng measured parameters to achieve intelligent monitoring environmental effects, thereby improving crop quality and yield.
