With the growing concern about the safety, durability and normal use function of large and important bridge, the research and development of bridge health monitoring system is developed. The purpose of this paper is to realize the system of real-time monitoring and security analysis results show the three-dimensional visualization, this paper studies the three-dimensional visual model of the bridge real-time security monitoring system. According to the functional requirements, the system is divided into three parts, such as 3D graphics engine, 2D graphics engine, database interface and so on. According to the idea of modern software engineering, a complete set of system architecture is designed, which makes the above modules work with high cohesion and low coupling. The system to the system development methods of the modern software engineering based, to all kinds of design patterns as a skeleton, integrated use of 3D modeling and rendering technology and GDI + and SQL database technology on the MFC platform is a great progress of the combination of computer software technology and monitoring system. At the same time, the success of the system development, the trial prove greatly improves the efficiency of the monitoring system of bridge, to predict bridge safety hidden trouble, ensuring the safe operation of the bridge to the very important role to promote the bridge monitoring technology development.
