Study on the Application of Video Surveillance System of Expressway Construction Based on 3G

Safety and quality supervision is an important part of expressway construction, the traditional regulation mode relies on artificial which exists objectivity and poor oversight, poor technical means and other issues, which brought a significant security risks to the project quality and safety. In this paper, based on the analysis of the existing video surveillance system, We explored the application of 3G technology in video surveillance system in the expressway construction. First of all, Composition and principle of the system are discussed in this paper. Secondly, the platform constitute of wireless video surveillance system is analyzed in detail, Finally, We summarized the application advantages of 3G technology in the expressway construction ,which is of great significance to enhance Expressway construction management.
