Application Of Real-time Wireless Transmission Technology

With the rapid development of China's national economy, all kinds of large structures is increasing. The importance of these large-scale structure is self-evident, in the event of damage, will result in huge casualties and property losses. Therefore, real-time monitoring of the health status of these structures is very important. Monitoring of large structures typically have more measurement points, wiring is difficult, and so large volumes of data, commonly used in vibration test technology has been difficult to meet the requirements. Wireless data transmission does not require wiring hair, simple construction, easy expansion and other characteristics, are very suitable for large-scale structural health monitoring. Combination of sensor network sensor technology, embedded computing technology, distributed information processing technology and wireless communication technology to collaborate in real-time monitoring, sensing and gathering information to monitor the object, and send the information to the user, in national security, industrial control , environmental monitoring, disaster relief, and many other areas has broad application prospects.Using wireless transmission and sensor networks and other advanced technology development of large structural health monitoring system will make users better understand the operation of the structure to reduce the tragedyThis article is a wireless sensor network system in the practical application and testing, and the parameters of the required hardware,performance indicators and a brief introduction, with emphasis on wireless sensor network system set up to implement a real-time information collection, wireless communications Analysis of transmission and control center to determine. Debugging and test results were also presented on the wireless sensor network systems long-term prospects. The main contents include:Firstly, the wireless sensor network system characteristics and advantages of a detailed exposition of the application while at home and abroad were presented and explore;second,described in detail based on the ZigBee standard for wireless sensor technology and its benefits,and In this article,the advantages to be a great application;again,This paper describes the various hardware used in the system, describes the functions used in this system, performance parameters and the use of standards. Finally, wireless sensor network system and terminal software, hardware, network design, and test and debug the system and achieve the object of surveillance monitoring.
