| Highway tunnel monitoring system is a very important part of highway tunnel construction. As the throat area of highway, the stable running of the tunnel daily traffic is the most important to ensure the normal running of the highway, therefore, the study of tunnel monitoring system is particularly important.Highway tunnel monitoring system is an integrated platform. On the basis of a full understanding of the device of highway tunnel, a detailed analysis of the working theories of them and the way of the data transmission, the dissertation gives a detailed requirement analysis of the system and a specific illustration of the tunnel field system construction. The system includes traffic monitoring subsystem, lighting monitoring subsystem, ventilation monitoring subsystem, firefighting monitoring subsystem, alarm and incident handling subsystem and information board monitoring subsystem and so on. In the detailed design phase, the dissertation gives a specific functional illustration of these subsystems. The system designed as three operating modes: monitoring and control center, the tunnel station and tunnel device, and among of them the tunnel station is the core of the whole monitoring station platform, it is responsible for the daily operations and the handling of the events from tunnel. The system can collect real-time data from the device, it can also control device under automatic mode or manual mode. Therefore,the system uses database handling data to ensure the speed of data processing and transmitting, and it sets up different roles and operating authorities for the users to ensure system security.The system can automatically handle real-time event occurred in the tunnel, and it is a real-time, efficient, accurate and comprehensive monitoring system. The test of the system shows its rationality and effectiveness. The dissertation can provide some references of the experience and methods for the design and research of tunnel monitoring system. |
