Intelligent transportation, large-screen display and intelligent analysis are essential

In actual operation, the intelligent transportation system has two major features, namely focusing on the wide application and service of traffic information and improving the operating efficiency of existing transportation facilities. The response to the display terminal is to ensure the linkage, efficiency and integrity of the information display system and the monitoring system. The large-screen splicing system can not only achieve ultra-large display to meet the centralized display needs of a large amount of information, but also achieve multi-window display to ensure that each monitoring signal is included and convenient for users to view at any time. In order to maximize the value of intelligent transportation systems, large-screen display terminals have become a rigid requirement.

The application of large-screen display in intelligent transportation is not only a port for display in the indoor monitoring center, but also plays a great role in the transmission of outdoor traffic information.

The uneven distribution of vehicles on the road is also one of the causes of traffic jams. Drivers do not know the traffic conditions on the road ahead. If they encounter a traffic jam but have no way out, they can only bite the bullet and "add to the jam." Then rationally allocate traffic flow, guide drivers to choose smooth and feasible roads during driving, and disperse traffic flow, which can not only alleviate road congestion, but also improve driving efficiency.

The traffic guidance information screen, also called the variable information board, is an integral part of the advanced traffic information service system and traffic management system and is used to publish real-time traffic conditions. Its working principle is to obtain real-time road traffic data through a real-time traffic flow data collection system. After these data are automatically processed by the computer system, they are automatically released to the display screen to provide traffic participants with traffic information on the relevant roads and road networks ahead. The information released includes traffic conditions (smooth, slow, congested), travel time and emergencies (traffic accidents, temporary traffic control and special weather), etc., providing direct reference for traffic participants to reasonably choose travel routes, and achieving the goals of evening traffic flow, reducing travel time loss, and improving road network operation efficiency.

Intelligent video analysis for autonomous monitoring and early warning

From the perspective of the main applications of intelligent analysis, there are two major development directions. The first is intelligent recognition technology represented by license plate recognition and face recognition, which are mainly used in electronic police, airports, and customs.

The other is behavior analysis technology represented by rules such as perimeter prevention, people counting, automatic tracking, retrograde driving, and no parking. It is mainly used in wall perimeter warning areas, shopping malls, traffic, and scenic spot traffic statistics, road prohibition of parking and release, illegal retrograde driving, scene tracking, etc.

1. Dual-machine automatic tracking: intelligent analysis camera plus ordinary speed dome method. Can be applied to urban alarm emergency plans. Object tracking for emergencies.

2. People flow statistics: Count the number of people entering and exiting the selected area, which can be used to analyze and count customer flow in supermarkets and shopping malls to help merchants formulate corresponding sales strategies. It is used in scenic spots and subway entrances to provide traffic data for personnel control applications.

3. Crossing the warning zone: Detect the perimeter by setting up virtual fences. When a suspicious person or object is found crossing the fence, an alarm is triggered and the alarm signal is uploaded to the monitoring and management center. At the same time, the alarm screen can be uploaded to remote monitoring users through the network. It can be used in crosswalks or zebra crossings on traffic roads, fences in key areas of factories, fences in schools, detention centers, etc.

4. Loss analysis: By drawing an area where important items are placed on the monitoring screen as a warning area, as long as the item leaves the warning area, the alarm rule will be triggered immediately. Used in key protected areas such as museums, exhibition halls, auctions, gold and silver shops, etc.

5. Direction analysis: In actual monitoring, people may be concerned about the direction of the flow of people and the direction of traffic flow. Through direction recognition, it can be judged whether the target is walking or driving illegally. If there is reverse behavior, the target will be automatically locked and the alarm will be sounded at the same time. Applicable to one-way roads; important entrances and exits, etc.
