In recent years, large steel structures in large public buildings in a wide range of applications, more and more innovative structural system, the form of more and more complex, increasingly large scale, has become the most important and the most active areas of contemporary architectural structure one. Accidents in the steel construction process, however, was in constant increase in the protection of the structural safety of the construction of the research and application of health monitoring technology in the steel construction process. The rapid development of the steel structure of the construction process health monitoring technology put forward higher requirements. This paper studies summarized the domestic and foreign steel structure construction process health monitoring method, the means and methods of the analysis of the deformation, stress, cable force, vibration, and construction environment in the steel construction process monitoring index system, and contrast and cited advantages and disadvantages of the two methods and the latest application instance. In addition, the calculation and analysis of the steel structure construction process theory, a brief summary of the content needs to be considered in the calculation of the steel construction process, the calculation method and load analysis. Through the study of wireless sensor network technology at home and abroad and its research progress in the field of civil engineering, summarized its advantages in the monitoring of civil engineering. On this basis, combined with the demand of the steel structure of the actual stress monitoring, from the design of miniaturization, low power consumption, low cost, high reliability point of view, to develop a set of vibrating wire strain monitoring system based on wireless sensor network technology detailed introduction to its hardware and software development, networking technology. The combination of long steel construction cycle features, such as 3G technology, stress monitoring of remote operation, monitoring cost savings, improved monitoring efficiency. And warning technology in the field of development, and put together the concept of early warning technology content. On this basis, in accordance with a clear police intelligence, looking for a police source, the analysis of the warning signs and pre-alarm level \The establishment of a system of early warning mechanism. To further study the safety warning theory, design a simple component of early warning test platform, which provides good conditions for further study. The binding the Ningbo steel structure covered bridges construction lifting process monitoring, wireless remote vibrating wire strain and acceleration monitoring system, measuring robots and other means of monitoring applications, the entire construction of the steel structure covered bridges lifting process of deformation, stress and vibration The whole process of tracking and monitoring and analysis, and the combination of the early warning system for early warning analysis presented in this paper, to ensure the smooth completion of the construction process.
