Design And Implementation Of Agricultural Sand Table Real-time Monitoring System Based On ZigBee Network

Agriculture is an important industry in the national economy,and it is the foundation of the national economy.The development of agriculture restricts the development of other industries directly.In order to realize the development of agriculture,it is necessary to apply modern science and technology to agriculture so as to realize the modernization of Agriculture.As an important part of agricultural modernization,agricultural greenhouse can provide the optimal growth and development environment for the crops,such as temperature,humidity,light,water and so on.Agricultural sand is a realistic scene modeling,can provide intuitive visual experience for people.In a laboratory sand table model,a sand table system consisting of ZigBee acquisition node,ZigBee coordinator and ZigBee control node is designed.The system uses a variety of sensors to collect greenhouse environmental parameters,such as soil temperature and humidity,ambient temperature and humidity,light intensity and so on.The collected environmental information is transmitted to the coordinator,and finally to the A8-information machine.A8-information machine to analyze the collected parameters,and then according to the control command to send commands to the control node.According to the received command and control node will open or close the greenhouse environmental control equipment.For example,the control node can be opened or closed through the fan,to regulate and control the environment for the growth of crops,provide accurate planting,visual management for agricultural production,intelligent decision-making,to realize the intelligent management of agricultural process.In the design of sand table system,firstly,the whole structure of intelligent monitoring sand table system based on ZigBee technology is designed.Secondly,the design of hardware and software of the system.The hardware design includes: ZigBee wireless transceiver module,various types of sensors,the coordinator,the selection and design of AC control module and a main control unit;the power supply system design and debug module design and so on.The software design includes: ZigBee development environment,using the IAR platform for the development of ZigBee protocol stack;ZigBee wireless network;design the acquisition node of the program;and monitoring real-time data for each region inside the sand table with A8 information machine,corresponding to the equipment for sand control.Finally,the system running and debugging.Sand table system vivid simulated greenhouse scene,the success of agricultural greenhouse visualization,played a very good networking teaching purpose.The design of sand table system can not only provide the networking teaching intuitive for undergraduates,but also for future research for networking research platform,contribution to the matter the network point force.
