Video surveillance solution for highway tunnels
Due to its unique geographical environment and usage characteristics, highway tunnels often become prone to traffic accidents. To ensure traffic safety, real-time and efficient video
surveillance systems have become necessary. Using the switch provided by our company and setting up
The ring network architecture can provide stable and reliable monitoring services for tunnels, while ensuring the security and efficiency of data transmission.
Scheme description:
Solution architecture:
Network topology structure: The video surveillance system for highway tunnels adopts a ring network topology structure to ensure the stability of data transmission. The access layer
adopts industrial 2 optical 8 electric ring network switches to build the most stable bandwidth link; The aggregation layer adopts.
The industrial 60000 megabit optical 48 gigabit optical switch is connected to the front-end access switch to form a ring network link, and then connected to the core switch through
optical fiber; The core layer adopts a frame type core switch to meet the access requirements of front-end switches.
Core switch: Deploy a rack mounted core switch in the highway management center as the data aggregation center for the entire toll collection system. This core switch has high-speed
data processing capabilities and rich port configurations to meet the access needs of various devices.
Ring network design: Multiple access switches are deployed along the tunnel to form a ring network through media such as fiber optic or twisted pair cables. This design ensures that
the failure of any node will not cause communication interruption, enhancing the stability of the network.
Video surveillance equipment access: Install high-definition cameras in key areas of the tunnel, such as entrances, exits, and intersections, and connect them to nearby access switches
through Ethernet cables to achieve communication with the core switch.
Data backup and redundancy: To ensure the security and reliability of data, the core switches provided by our company are also equipped with data backup and redundancy functions.
When the main switch fails, the backup switch can quickly take over data transmission tasks to ensure communication continuity.
Advantage analysis:
High reliability: Ring network design can avoid communication interruption caused by single point failures and improve network reliability. At the same time, data backup and
redundancy functions further enhance the stability of the system.
Efficient data transmission: Both core switches and access switches should have high-speed data processing capabilities to meet the real-time data transmission needs of electronic
police and ETC toll collection systems.Strong scalability: This solution has good scalability and can add access switches and related equipment according to future business needs, facilitating network upgrades and
maintenance.Easy maintenance: The ring network structure makes fault location and maintenance more convenient, reducing operating costs and maintenance difficulties.
The video surveillance solution for highway tunnels based on switch ring network architecture can provide stable, efficient, and reliable monitoring services, ensuring the safety and
smoothness of traffic. Through reasonable network planning, high-quality equipment selection, strict adherence to standards, and training support, this solution
The solution will bring many conveniences to the tunnel management of highways and provide strong guarantees for traffic safety. Meanwhile, with the continuous advancement of
technology and the increasing demand for applications, this solution will continue to be optimized and improved to meet the needs of future transportation development.
