At the same time, tunnel traffic has the characteristics of large flow and fast driving speed, and contains a large number of lighting, fans, pumps, indicators, information boards, power supplies and other equipment and facilities. If there is an emergency such as traffic accident or equipment failure in the tunnel, it will have a great impact on the safety of people and transportation in the tunnel.
Then, in the current practical work of highway tunnel management, due to the scattered layout of highway management and different division of labor among departments, the tasks of on-site disposal, centralized dispatching and decision-making command are relatively independent, and a unified vertical and horizontal command and dispatching system has not been formed.
Therefore, it is urgent to improve the level of intelligence, informationization, integration and green energy saving of highway tunnels in China, and transform the existing traditional management mode of compartmentalization into an innovative intelligent comprehensive monitoring mode. A visual management scheme to realize full connection and intelligence of intelligent tunnels-intelligent tunnel center dispatching platform. Guided by comprehensive tunnel management and control, improve the comprehensive business capabilities such as equipment control, event early warning, process management and emergency response. Help the tunnel operation control develop in a smarter, safer and more convenient direction, and promote the digital transformation and upgrading of the transportation industry.
The three-dimensional scenes in the system all adopt lightweight modeling method, which not only restores the overall building structure, internal equipment and facilities and the surrounding building road environment of the tunnel, but also supports the smooth display of the home page and displays the relevant operation and management data of the integrated tunnel.
With the vigorous development of tunnel traffic construction in China, various fire safety hazards emerge one after another, which brings great pressure to tunnel fire safety work, and traditional fire prevention means are difficult to deal with. Hightopo uses lightweight three-dimensional modeling technology to digitally duplicate the scene fire situation by docking platforms such as automatic fire alarm system, evacuation indication and fire broadcast.
Displaying the implementation process and details of the emergency plan in the tunnel through the background data interface, and making corresponding emergency measures in conjunction with on-site equipment and facilities, is conducive to real-time monitoring and inspection of fire-fighting facilities in the tunnel, and plays an important role in improving the safety factor of the tunnel and quickly handling fire accidents.
Complicated mechanical and electrical equipment and special environmental factors make the tunnel always face difficulties such as emergency command, supervision and operation. Digital twinning technology integrates equipment alarm information, fault information and other data, and digitally upgrades tunnel electromechanical equipment supervision. Break the information island and realize the intelligent cooperation of tunnel equipment.
Support manual clicking to view equipment information, including the total number of equipment, the number of equipment failures, the number of idle equipment and other information; Support rapid positioning according to the alarm information sent by the equipment. Operation and maintenance personnel can know the health status and maintenance of the equipment, including the number of processed and unprocessed, and display the location and time information on the 2D billboard.
In the front scene, the position of the fan in the tunnel and the corresponding parameters are displayed. Click the main button on the left to view the layout of the fan equipment. The failed fan is marked with a red fan icon. Click the corresponding fan in the scene to view the device number, device stack number, device direction, communication status and fault status. Managers can adjust the operation mode of ventilation system in time by remotely controlling the indicator signs in the fan or tunnel.
Relying on remote network patrol, intelligent forecasting and early warning can change passive waiting into active capture. Users can find abnormal road conditions at the first time with a click of the mouse and deal with them in time, saving disposal time and improving work efficiency. The positioning system is connected with the on-site camera. When there is an emergency alarm event or the designated personnel are strictly controlled, the live video images can be automatically switched according to the location information, which can help the supervisors to save the time of retrieving the video monitoring images and relieve the fatigue of the monitoring video images.
Grasp the overall traffic situation of the tunnel comprehensively and accurately.
The traditional monitoring system scheme only relies on video to identify the traffic conditions in the tunnel, and its accuracy and breadth are often limited by the video monitoring ability, which can not meet the needs of tunnel operators to comprehensively and accurately grasp the overall traffic conditions of the tunnel. Relying on charts, floor plans, three-dimensional graphics, videos and other forms to visualize the tunnel, a smart tunnel center dispatching platform is constructed, which can accurately cover the whole tunnel traffic state perception system and improve the tunnel precise control ability.
Tunnel traffic safety management system with full closed-loop process.
At present, tunnel management mainly focuses on the detection and disposal of traffic accidents and incidents in the tunnel, but there is still a lack of control over dangerous vehicles entering the tunnel. Construction of intelligent tunnel center dispatching platform, through linking different monitoring content and monitoring mechanism platforms inside and outside the tunnel, integrated tunnel safety comprehensive application, and realized tunnel traffic safety management business.
