Based On Wireless Sensor Networks For Indoor Temperature Monitoring System Design

Temperature monitoring is to ensure that heating enterprises to improve the quality of an important means of heating, automatic temperature control technology to achieve the key link, through real-time acquisition and control of temperature, can achieve energy saving and pollution reduction goals. In this paper, based on ZigBee wireless sensor network technology to address the heating room temperature monitoring the user is a low-cost wireless sensor networks in the field of heating control of a new attempt to.Wireless sensor networks is a hot spot for research in internation, attention from the multidisciplinary study of a high degree of cross-frontier of the emerging, which combines sensor technology, wireless communication technology and computer technology development, with information collection, transmission and processing capabilities.At the same time,the ZigBee technology is a wireless sensor network technology with low cost, low power and simply application,which is a new direction of development of wireless sensor networks.This paper mainly for the following aspects of the study:1.Wireless sensor networks and ZigBee protocol, this paper on the concept of wireless sensor networks and architecture on the basis of the study, focusing on the characteristics of the ZigBee protocol, protocol stack architecture, and finally ZigBee technology with other wireless communication technologies, compared exposition the feasibility of using ZigBee technology.2. Of wireless sensor networks and ZigBee protocols of the study and research on the concept of wireless sensor networks and architecture on the basis of the study, focusing on the characteristics of ZigBee protocol, protocol stack architecture, network topology and network-depth discussions carried out the work process, and finally ZigBee technology with other wireless communication technologies, compared discusses the feasibility of using ZigBee technology solutions.3. Proposed based on ZigBee technology, the temperature monitoring system design, including system node hardware design and software design and monitoring of network topology determination.4. The completion of the system node hardware design work, the main components of the selected on the basis of research and draw out the system node circuit schematic and PCB circuit board diagram.5. According to the design mandate, the use of the node is designed hardware, set up a ZigBee-based MESH networking protocol, and the program flow chart, based on the study of the application function calls, and finally completed the preparation of the application6.The use of design and development of software and hardware equipment, the group net experiments, experimental results are given.Finally, the paper summarizes the work, and the next step was prospected.
