1、 Background of the plan
With the continuous increase of relevant policies on the informationization construction of highways, as well as the development and innovation of landmark technologies such as the Internet of Things, 5G, big data, and new energy, the informationization construction projects of highways in various regions are increasing day by day. The informationization construction of highways mainly revolves around three major systems: monitoring system, toll collection system, and communication.

- Monitoring system transmission
The monitoring system needs to connect the surveillance cameras deployed in various sections of highways, bridges, tunnels, etc. to the monitoring center through network access. Tunnels, road exteriors, and other complex environments have long communication distances and strong electromagnetic interference, ensuring smooth data transmission.
- Analysis of Toll System Transmission
The toll system is interconnected through switches deployed at toll stations and toll sub centers, ensuring the safe and stable operation of the toll business system.
- Analysis of Communication System Transmission
The communication system utilizes fiber optic resources along the highway, deploys corresponding switches, and forms a communication transmission network to achieve interconnection between the sub center of the road section and the toll stations within the road section. It is an essential means to ensure the safety, high-speed, smooth, comfortable, and efficient operation of the highway.
2、 Solution
- Transmission scheme for monitoring system
By deploying industrial grade perception switches in scenarios such as tunnels and road exteriors, a ring network is formed to build a 20ms level fault protection capability, achieving network interconnection and reliable transmission. Each access ring network is connected to the sub center through the monitoring aggregation switch at the road convergence point. The core switch of the sub center is interconnected with the provincial monitoring center, completing the province wide controllable and traceable monitoring system.
- Toll system transmission scheme
By deploying industrial grade three-layer switches at each toll station and three-layer network switches at the toll sub center, interconnection is formed. The toll sub center is connected to the core switch of the provincial center through the provincial transmission network, ultimately achieving full interconnection of the toll system network and ensuring the safe and stable operation of the toll business system.
- Communication system transmission
By utilizing fiber optic resource components along the highway and based on 10 Gigabit Ethernet ring network technology, the backbone ring network bandwidth can reach 10G, 20G, and 40G, achieving interconnection between road sub centers and toll stations within the road section.
