Always go but do you really understand the highway video surveillance system?

With the large-scale construction of domestic expressways and the improvement of expressway networks, monitoring and management of expressway tolls and road sections has become an important part of highway management.

Highway monitoring system is essentially a closed-loop system. Video surveillance is mainly responsible for the collection, processing and storage of data, video, and road conditions, and provides traffic information resources. Provides fast, safe, comfortable and efficient highways.

Highway monitoring system can be divided into toll monitoring system, road monitoring system, monitoring center and bureau monitoring center.

Charge monitoring system

The charging monitoring system mainly focuses on the toll collection of the toll station lanes, toll plazas and toll booths, observes and records the types of vehicles that the toll lanes pass through, the operation procedures of the toll collectors, and the emergencies and special events during the toll collection process. Effective supervision.

For example, toll station monitoring, charging stations are mainly responsible for recording the types of passing vehicles, and at the same time supervising and recording the toll collection process, usually requires the deployment of video surveillance in the two directions of toll lanes and toll booths.

Road monitoring system

The road monitoring system is mainly to supervise key expressway sections such as highway trunk lines, interchanges, and tunnels, and master the freeway traffic conditions. It will promptly discover traffic congestion sections and illegal vehicles, and provide timely guidance to ensure the safe and unimpeded expressway.

Tunnel monitoring

The speed on highways is at least 90, 100 kilometers per hour. If you are in a tunnel section at such a high speed, the danger is much higher than the average road section. Therefore, the monitoring system of the tunnel requires a moderate size, can adapt to the backlight of the lights, waterproof and dustproof functions.

Road monitoring

The road monitoring system needs to conduct macro-monitoring on the dynamic status of traffic flow so as to enable real-time forensics and review of various abnormal conditions and achieve timely processing. The general monitoring front-end uses an integrated high-definition color monitor to send high-definition video images to the monitoring center through the transmission network.

Monitoring Center

The monitoring center is divided into the charge monitoring center and the communications monitoring center.

Charge monitoring center

It is mainly responsible for the management of video images and sounds within each toll station within the jurisdiction, as well as the toll collection transaction data for each toll station. These data and graphics are monitored and analyzed from time to time, and exceptions, unexpected events, and emergency incidents are monitored and handled in a timely manner. The monitoring center has the right to publish and mobilize the information of the toll stations under its control. The smooth flow and normal operation of toll stations.

Communication Monitoring Center

Responsible for managing the collection of data related to the surveillance of inter-division, intercommunication, tunnels, slopes, road surface conditions, weather conditions, etc., comprehensive analysis of these data, monitoring and investigation of road conditions, and timely Externally issued relevant information to warn vehicles on road traffic congestion, accident areas, frozen road sections, and rain and snow road sections, and induce and instruct vehicles passing by in advance so that users can understand road conditions more quickly and easily, so as to avoid delays and errors. The trip.

Bureau Monitoring Center

The Bureau's monitoring center carries out unified monitoring, management, and dispatch of all expressways in the province, and is divided into a charge monitoring center and a communications monitoring center.

Each charging monitoring center uploads its own video signals to the charging monitoring center. The charging monitoring center has the option of viewing and monitoring several images. Special events and emergencies can monitor all uploaded images. At the same time, it records, manages, and queries upload transactions and data at a charging center.

The communication monitoring center will uniformly manage and monitor the video images and collected data uploaded by each communication monitoring subcenter, and at the same time display the traffic conditions and lane occupancy rate of all roads in the province, and coordinate and schedule them in a unified manner.

Conclusion

According to the operation data of the expressway monitoring system, it not only can reduce the traffic jams and vehicle delay time, but also can reduce traffic accidents, shorten the transportation time, and exert the fast, safe, comfortable and high-efficiency function of the expressway.

On the one hand, advanced technology is used to integrate disparate and isolated roads, traffic, environment, and event information. Through information processing and control systems, information collection and information dissemination are organically combined to achieve a true sense of Interaction and interaction.

On the other hand, to take advantage of the overall road segment and road network, a single system that is isolated and responsible for a single road segment will be gradually developed into a large-scale comprehensive information network to provide road users with more comprehensive and thoughtful services. This ensures high-speed, safe and economical operation and management of the highway.
