Design And Implementation Of Wireless Standard Measurement System Based On ZigBee

With the development of the science and techonoledge, the quality of life had been improved, there is growing concern about the problems of building health. People can get important information through real-time monitoring the structural parameters, on the basis of this information to judge the health of buildings, and then a series of measures to be taken to ensure the safe use of the building. However, in the existing building health monitoring system,the layout of line is very complicated, complex and costly, not suitable for large building's angle measurement. To solve this problem, People use the wireless sensor network technology in real-time monitoring system, simplifies the development of the system, and reducing system cost.This paper presents a new wireless level measurement system combines a wireless sensor network and ZigBee wireless communication technology, realized the function of the large building's angle measurement. This system can monitor the building's angle effectively at different positions through wireless sensor networks, does not require build extensive line,and the system's energy consumption low, stable performance, simple, easy to implement and has very broad application prospects.This paper analyzes the structures and methods of angle measurement principle and technical characteristics of sensor networks and ZigBee, proposes the function of the system requirements,determines the system's goals to be achieved, and develops the corresponding design method according to the characteristics of the system. The paper introduces the system's hardware and software implementation process, including the device selection and circuit design, as well as the development environment and program flow of related software.First, the system uses CC2430 radio chip, SCA103T angle sensor and the LCD liquid crystal display to build the hardware platform, and achieve the functions of angle data acquisition and transmission.Develop the host computer software to dynamic display of data and store it in a database,by using object-oriented and visualized programming environment,for user-friendly query and analysis operations. Second, for the shortcomings that the wireless sensor networks has a large number of nodes, the energy, memory resources are limited and the application environments of the wireless level measurement system, optimizing the system network topology and routing protocols, and changing the existing routing algorithm to enhance the network robustness and security, reduce network energy consumption, while increasing the network lifetime.This article tests the system's overall performance by simulation experiments and proves that the system can achieve the desired functionality, the hardware node and host computer software can work correctly, be able to monitoring of the angel of building in real-time.
