Design And Implementation Of Temperature And Humidity Control System With ZigBee Location Information

With the development of social progress,electronic technology and computer science technology,environmental monitoring and control system has also get the level of technology and modernization.Data collection and display of environmental factors such as temperature and humidity has become closer to regional precision display.Temperature and humidity are considered as one of the most basic parameters in industry and agriculture,manufacturing and equipment storage.Using modern technology to collect,display and controlling real-time temperature and humidity can effectively improve work efficiency and economic value.A temperature and humidity control system with Zig Bee location information is designed in this system.This paper introduces the importance of temperature and humidity control system with Zig Bee location information firstly,the status of Zig Bee wireless technology,the research level of positioning technology all over the world,Besides the research history and current situation of temperature and humidity control system were introduced.Then the protocol specification of Zig Bee and the working principle of each layer are analyzed,and the structure and formation process of Zig Bee network are analyzed.A few large indoor wireless positioning technology are introduced,the positioning mechanism of indoor wireless positioning technology and positioning method based on RSSI are introduced in detail,the common positioning algorithms are introduced,the chip used in positioning engine and working principle are introduced in detail.The system based on Zig Bee wireless communication protocol is designed for temperature and humidity acquisition and control system.Because it uses Zig Bee positioning technology,it can display the areas where all temperature and humidity nodes are located.The design of the system makes full use of low power Zig Bee communication protocol,network capacity and reliability advantages of wireless sensor network node using Zig Bee a temperature and humidity,temperature and humidity information acquisition using Zig Bee wireless sensor network,and the temperature and humidity information analysis,storage,and ultimately can be monitorred information collection,showed in front of the observer on the PC software control center.According to theory knowledge mentioned and learned on the temperature and humidity control system,the design of the main software and hardware are designed in the coordinator,the temperature and humidity monitoring node and beacon node within three modules of network hardware,There is the hardware design of electric circuit system diagram in detail.The software of the indoor positioning algorithm,temperature and humidity acquisition function,PC software and network communication and other aspects of the implementation and Realization code are designed.In the test,the results of the analysis of the data are listed.The result of the final system realization shows that the proposed Zig Bee temperature and humidity monitoring system with location information can achieve the desired results.
