State monitoring is one of the important part of the structure healthy monitoring system, the dynamic characteristics of structures are evaluated rather frequently by measuring their vibrations. With the research and application going in deep, wireless sensor is a perfect way to expand the range of the structure health monitoring system. This dissertation started with a concept design of a wireless sensor that could be used in the structure health monitoring system. In this paper, the state monitoring of civil engineering structure by using wireless sensor technology has been gave out based on monitoring technology and network protocol analysis. Design and hand make the front-end measurement circuit board and software for secondary development based on the monitoring equipment of company. The monitoring network has been set up and experiments were carried out about the structure deformation in the standard steel beam of civil engineering structure laboratory.

Abstract This paper describes a design of wireless distributed SHM (Structure Health Monitoring) system with a particular emphasis on comparison of wireless communication standards. The presented solution is being deployed in the TULCOEMPA project. Several wireless communication standards are compared, with their benefits, disadvantages and typical areas of application. A choice of proper ISM (Industrial Scientific Medical) band and reasons for use of Wireless Sensor Networks are also discussed. The last part of this paper presents the proposed structure and designed prototype. The chosen architecture of the system and the program algorithm used for communication and measurements are described.

Cable Stayed Bridge

Steel and concrete are the main buiding material of the civil engineering community, but with its easily errosion behaviour and CO2 discharge, it should be substituded with new materials.Fiber reiforcement polymer (FRP) is such a developped material, with its high strength to weight ratio, durability prolongation, hight stiffness to weight ratio and its fatigue resistance behaviour, it is now getting widely used in civil engineering. This article focused on how to design, built and operate a structure health monitoring system for the noval steel-free cable stayed bridge, and a knowledge discovery model, SG（Simplified-General）modle was provided for analyzing the collected data.

Medical Health

Due to the gradual improvement of living standards in recent years and the continuous improvement of China’s health care awareness, the aesthetic medicine model has gradually changed from the treatment mode of disease treatment to the prevention mode of early detection and early treatment. Meanwhile, wireless sensor networks (WSNs) are gradually infiltrating into the medical field due to their low power consumption, small size, wireless transmission, and portability which complies with the needs of the development of medical models. Therefore, this paper studies and implements a beauty medical health monitoring system based on WSN and ZigBee short-range wireless transmission protocol; moreover, wireless power transfer (WPT) technology is used for charging sensors. Experimental results demonstrate the feasibility that the maximum power levels converted in sensors by the WPT for different ISM bands can meet the average power consumption expected in the range of 200–500 μW. And the designed system can provide an important practical reference for promoting the informationization of telemedicine and the development of beauty medical systems in China.
