プロジェクト紹介


The rapid development of China's domestic economy has led to an increase in the number of highway and tunnel construction projects being conducted around the country. In the interest of maintaining a secure and safe highway and tunnel system, much emphasis is being placed on building robust tunnel monitoring and control systems. Western countries began researching advanced tunnel control systems in the 1960's. Since then, some developed countries, such as Japan, The United States, and various European countries, have developed different types of tunnel control system. The development of new technology for computers, image processing, communication, control, Ethernet, and system busses has led to a big improvement over the old technology, making it possible to increase the communication speed used by the monitoring and control systems used in tunnels.


System Description


This project uses 10/100 Mbps Ethernet as the main communication medium, with Turbo Ring topology used to increase reliability. Profibus is used to transmit control signals between substations (max. speed of 12 Mbps), and uses Ethernet to connect monitors, highway MIS, GIS, GPS, and monitoring stations (at 10/100 Mbps) for management. The modulated scheme and friendly WINCC Chinese user interface are advanced methods that are used widely around the world. Baifeng Tunnel has left and right openings on each side, with the left opening stretching a distance of 1,974 meters, and the right opening stretching a distance of 1,540 meters. The main communication and monitoring network system uses Moxa ED6008-MM-SC to build a ring topology that connects to the main control room using IMC-101-M-SC over long distances.
