I. Overview:　

　With the inter-urban economy, trade, travel increasingly close, highway as an important mode of transport with fast speed, traffic volume, service level advantages to become the main carrier of modern transportation systems sector. Accidents can happen at any time hidden suffering! Eye

Industry before using intelligent monitoring and management system, traffic data and information for centralized monitoring, analysis, and provide daily management of the incident command decision. System to ensure smooth traffic, reduce accidents at the same time, enhance the management of modern transport

Ability to control and effectiveness.

Second, highway monitoring display requirements:　

   Intelligent highway monitoring systems typically have multiple subsystems: image monitoring subsystem, the data transfer subsystem, schedule management subsystem and other professional systems, digital systems, network-based, high-definition into application characteristics. Highway monitoring system structure

Generally can be divided into three levels, from the bottom up include:

       (1) toll: each toll station needs local video signal monitoring. The toll stations under the jurisdiction of the camera signal is fully incorporated local video surveillance systems, charging stations for local monitoring and management of all images.

       (2) monitoring and control center: a highway is usually set several sections of the monitoring sub-centers, respectively, of a road monitoring and management. Each toll road to upload images to select several sections according to the requirements of monitoring and control center, monitoring and control center section of the toll road on the

Station uploaded images unified monitoring and management.

       (3) the provincial monitoring center: provinces Highway Administration requires all highways in the province unified monitoring, management and scheduling. The Area Control Center will own the video signal within the jurisdiction of the option to upload to the provincial center, the provincial center of unified monitoring and management

Management. Provincial centers, control centers, the use of hierarchical control network between the monitoring and control center. Control signals using forward stepwise form is forwarded to the need to control the device.

Through intelligent monitoring, highway monitoring center to achieve all toll stations, road traffic, weather conditions and other real-time monitoring. Vehicle accidents and congestion, the section of the incident immediately call the GIS, call the police patrol vehicles (GPS monitoring and dispatching system

EC), arrive on-site counseling and failure to lift.

The toll station, monitoring and control center, the provincial monitoring center tripartite collaboration, real-time monitoring system, greatly speeding up management departments at all levels to grasp the scene motorway quickly resolve traffic congestion, illegal vehicles, fog and other issues.

三、数字拼接墙系统在高速公路的解决方案：
　　Holley Connaught introduced for IP video applications to splicing system is mainly used for transportation, public security and other areas, to achieve the industry's demand for displaying a plurality of IP video surveillance applications, and whole sections of the geographic information system GIS, police patrol vehicle GPS monitoring and scheduling

The display system needs. Splicing system can provide large quantities of remote IP video surveillance with direct access to processing and display, the image display quality good and stable, has good compatibility and good subsequent expansion capabilities and front-end network equipment. Many types of sources seamless access capabilities,

And has sufficient capacity to meet the expansion needs of the display monitor when the number of upgrades in the future, to further protect the investment interests of users.

　　Flexible display wall system solutions

    Holley promise to provide suitable monitoring environment LCD splicing highway used by the display unit, the display can show the signal according to the needs and environment of space, spliced into any size video wall. Splicing system powerful all-digital distributed processing capabilities,

Meet a variety of digital IP / analog video, high-resolution GIS, GPS application of integrated high-definition display.

　　Holley Connaught in highway monitoring benefits of the solution:

　　Distributed processing to enhance the display performance of the system and display speed

　　All-digital distributed processing system: distributed parallel processing architecture, each of the signal processing nodes share the load, the system has a powerful signal processing capability to meet the needs of demanding applications on the system fast refresh; overall system security.

　　Large number of IP access and video decoding processing capability

　　Each channel can display twenty signals, large number of connections IP video sources. Spliced smaller display can meet the needs of the user to monitor a large number of sources.

　　Digital image processing allows each channel clearer picture quality

　　High picture quality: pixel precision splicing system-wide digital data stream to ensure end to end transmission of the signal, no signal transmission loss and loss is substantially produced in HD, coupled with the unique dynamic Holley promise smooth edge of the screen technology, each quality is more

perfect.

　　Powerful scalability and compatibility to save investment costs

　　Complete scalability and compatibility: the user to monitor the presence of pre-investment environment generally, later upgraded to expand demand, splicing system uses a modular design, fully compatible with analog control user pre, post or scale system capacity upgrade, just in the signal acquisition end changes without corresponding increase in acquisition module system platform, easy, flexible and effective protection of the user pre-investment and post-investment cost savings.

　　Splicing system will bring high-definition monitor mosaic art, revolutionized integrated and intelligent.
