I. Overview:

As the economy, trade, and travel between cities are getting closer, the expressway as an important mode of transportation has become the main carrier system in the modern transportation field due to its advantages of fast speed, large traffic, and high service level. Hidden accidents may occur at any time! Currently, the industry uses an intelligent monitoring and management system to centrally monitor and analyze traffic data and information and provide daily management and command decisions at the time of the incident. While ensuring the smoothness of roads and reducing hidden dangers of accidents, the system enhances the management and control capabilities and effectiveness of management departments in modern transportation. 

2. Display requirements for expressway monitoring:  

Intelligent highway monitoring system usually has multiple subsystems: professional systems such as image monitoring subsystem, data transmission subsystem, and dispatch management subsystem. The system is characterized by digitization, networking, and high-definition. The structure of the highway monitoring system can generally be divided into three levels, including from the bottom up: 

(1) Toll station: Each toll station needs to monitor the local video signal. The camera signals under each toll station are all introduced into the local video surveillance system, and the toll station monitors and manages all local images.

(2) Sub-centralized monitoring: A highway usually has several sub-centers for monitoring and management of a certain road section. Each toll station image is selected according to the requirements of the road section monitoring center, and the road section monitoring sub-center conducts unified monitoring and management of the images uploaded by each toll station in the road section.

(3) Provincial monitoring center: Each provincial highway authority needs to conduct unified monitoring, management, and dispatch of all expressways in the province. Each district monitoring center uploads the video signal within its own jurisdiction to the provincial center, which is uniformly monitored and managed by the provincial center. The provincial center, monitoring center, and monitoring center use networked hierarchical control. The control signal is forwarded to the device to be controlled in a progressive forwarding manner.

Through intelligent monitoring, the various monitoring centers of the expressway can realize real-time monitoring of the traffic volume and weather conditions of toll stations and highways. In the event of a vehicle accident and obstruction, immediately call the GIS road section of the incident, call the police patrol vehicle (GPS monitoring and scheduling system), and arrive in time for on-site grooming and troubleshooting.  

The three-party linkage and real-time monitoring system of the toll collection station, the monitoring center, and the provincial monitoring center has greatly speeded up the management departments at all levels to keep abreast of the on-site conditions of the expressway and quickly resolve traffic congestion, illegal vehicles, and foggy weather. .  

Third, the digital videowall system in the highway solution:

Excellent Color has launched a splicing system for traffic, public security and other fields that use IP video applications as the main application. It can fulfill the display requirements for multiple IP video surveillance applications in the industry, as well as GIS and police patrols for all road geographic information systems. Display requirements for vehicle GPS monitoring and dispatching systems. The splicing system can provide direct access and processing display for remote large-scale IP video surveillance. The image display is of good quality and stable, and has good compatibility with the front-end network equipment and subsequent expansion capability. Multiple types of signal source seamless access capabilities, and have sufficient expansion capabilities to meet the display needs of the upgrade in the future monitoring quantity, and further protect the user's investment interests.   

Flexible Tiled Display System Solution

Excellent color can provide liquid crystal splicing display unit suitable for use in the highway monitoring environment. The display screen can be spliced into any size splicing wall according to the display signal requirement and the size of the environment space. The powerful digital all-in-one distributed processing function of the splicing system meets the comprehensive high-definition display of various digital IP/analog video, high-resolution GIS, and GPS applications. 

Superior Color Superiority in Highway Monitoring Solutions:
Distributed Processing Increases Display Performance and Display Speed in Systems 

Full-digital distributed processing system: a distributed parallel processing architecture in which the signal processing nodes share the load, so that the system has a powerful signal processing capability to meet the application requirements of the rapid refresh of the system in a harsh environment; the overall system security is high.

Large number of IP video access and processing decoding capabilities

Each channel can display more than 20 signals at the same time, and a large number of connected IP video sources. The use of smaller splicing can also meet the display needs of a large number of monitoring sources.

All-digital image processing makes every picture more visible

High picture quality: the pixel accuracy of the end-to-end transmission guaranteed signal of all-digitalized data stream of the splicing system, lossless and loss of transmission signal is the basic of high-definition picture quality, combined with the unique dynamic picture edge smoothing technology , make each picture more perfect.

Powerful scalability and compatibility saves investment costs

Complete scalability and compatibility: The user monitoring environment usually has pre-investment, and the need for later upgrade and expansion. The splicing system adopts a modular design, is fully compatible with the user's previous simulation monitoring, and the later system capacity or scale upgrade, only The signal acquisition end increases the corresponding acquisition module without the need for changes to the system platform. It is easy, flexible, and effective to guarantee the user's upfront investment and save on late-stage input costs. 

The stitching system will bring revolutionary changes to the HD, integration and intelligence of the surveillance splicing field.
