Programme introduction
HD iDVR highway video surveillance system solution scheme in view of the problems existing in the highway of the various sections of the monitoring the "information isolated island" and the whole highway "information gap", according to the Ministry of transport GB/T28059 standards for the construction of the highway video monitoring integrated management system, the integration of compatible resource monitoring has been built and with seamless transportation department and the Provincial Department of transportation management platform for video surveillance, realize resource sharing and cascade control, improve the management level of video monitoring and emergency response capabilities, to the greatest extent play to the highway traffic capacity, improve the service level of the highway.

Background and challenges
Expressway video surveillance system is mainly of toll station, tunnel, service area etc. monitor, after more than 10 years of development, due to different sections in different period of system monitoring technology and equipment manufacturers, resulting in all sections of the monitoring system cannot be fully compatible and interoperable, can not give full play to the traffic monitoring global path induction, multi path traffic regulation, network scheduling, deal with emergencies promptly unified scheduling functions, to maximize the play to the highway traffic capacity, the construction of interconnection of network video monitoring system is imminent.

Solution
HD iDVR highway video surveillance system based on TCP/IP network architecture to achieve the image of the network interconnection, can facilitate the smooth upgrade and expansion of the system. The system consists of two parts of the road section and the monitoring center:
Section of the road through the deployment of video server to achieve the access to the video has been built, and through the streaming media server to achieve the sharing of video images;

Monitoring center through the deployment of all the sections of the video monitoring integrated management system platform for access to the video server; through the main control terminal, decoding terminal realize video image on the wall display, deploying streaming media server and share the video preview; through the web server provides remote access to the B / S mode.

Project advantage

1) using the standard protocol
System equipment and software support for the access and exchange of a variety of standardized protocols.

At the device level: support for direct access to devices that meet the onvif standard protocol; and support direct access to devices that meet the GB/T28181 specification;

In the platform layer: support and meet the GB/T28059 standards and GB/T28181 standard protocol interoperability platform. At present, the Ministry of transport system are using GB/T28059 interconnection, such as: Transportation Department, the Ministry of transportation network center, etc..

2) support multi level networking
Highway video surveillance integrated management system platform to support the highest four networking, you can effectively with the high-speed traffic police, the Ministry of communications, the Communications Department of flat / higher level units for video networking.

3) support a wide variety of business expansion
Platform in addition to support access video monitoring, traffic monitoring, extended event detection, weather monitoring, information dissemination, and other various business functions to meet the demand of the application, breaking the traditional control mode in the presence of business barriers, make monitoring more efficient.

4) support mobile client
In order to facilitate the monitoring of mobile applications, the platform supports mobile phone client access monitoring system. Side platform deployment of special mobile phone access to the server, through transcoding provides for a smart phone decoding and playing small video streaming, mobile client provide including real-time preview, video playback, PTZ control based video monitoring service.

And industry applications aiming at the characteristic of highway, the highway platform mobile client can further include high-speed news, high speed diagram and fast browsing and function to obtain real-time highway travel tips, and support the view above the highway traffic incident information and highway roads construction information etc.; through high speed diagram to reasonable planning route to obtain real-time traffic information.

By mobile phone customers, can be the highway video surveillance, event information alarm, construction information, traffic congestion and other centralized display, around the theme of high speed traffic services to a variety of presentation.

5) compatible with GB/T28181
Expressway video management platform, except in the device layer support access onvif equipment outside, and is also compatible with equipment in line with GB/T28181 protocol. At the same time, at the level of the platform, in addition to the support GB/T28059, also compatible conforms to the GB/T28181 protocol platform.
