The Trend and Application of Smart City and Traffic Speed ​​Dome

First, the development of high-speed ball in the smart city The high-speed dome camera is an intelligent camera front-end, which is called the high-speed intelligent dome camera, or the integrated high-speed ball/smart ball, referred to as high-speed ball or fastball. High-speed dome is one of the most sophisticated camera front end of the surveillance system. It has been widely used in safe cities, airports, rail transit, electric power, education, retail and other industries in recent years, and is increasingly referred to as wisdom. eye".

The high-speed ball in the smart city The development of the intelligent high-speed ball The features of its fast speed and multiple intelligent monitoring methods make it widely used in the safe city system. The following uses the road monitoring part of the Safe City system as an example to look at the specific application of the high-speed ball.

Urban intersections are often areas where accidents occur frequently. At the same time, they are also places where high-speed balls give play to their advantages:

1. Because the high-speed ball can achieve 360 ​​continuous monitoring, so at a junction with a high-speed ball can achieve all-round monitoring, high-speed ball high-speed rotation feature allows the monitoring staff can well capture the desired video. It is worth mentioning that the current mainstream high-speed ball manufacturers provide the technology of automatically matching the focal length and the rotational speed of the high-speed ball, so that the ball machine can provide stable video effects regardless of the rotation in the case of large or small zoom. The advantage is obvious in close-up surveillance.

2. The high-speed ball can realize the scan monitoring between two points, which is used to monitor the fixed area, and can also switch monitoring between several intersections, or the user can set the monitoring route and speed, so that it can be monitored cyclically. For the high-speed ball with the guard position function, when no one is controlling, the guard position function can be automatically enabled to perform monitoring and cruising in the set manner.

3. In combination with the intersection of alarm equipment, in case of alarm, through the high-speed ball alarm function to achieve video linkage and output linkage, to achieve a rapid alert response.

4. Intersections usually require 24-hours-a-day surveillance, and high-speed domes with built-in color-to-black, low-illumination cameras allow for better surveillance at night.

5. Traffic Surveillance and Guidance: Through the system, the on-site images in the surveillance area will be transmitted back to the command center, so that the management personnel can directly grasp the traffic conditions such as queuing, traffic jams, and traffic lights, adjust the signal timing, or use other means to divert traffic and change traffic flow. The distribution, in order to achieve the purpose of relieving traffic jams, automatically tracks illegal vehicles.

The intelligent high-speed dome camera has a unique "smart patrol" function, which enables the crew to free themselves from the complicated operations. In the event of an emergency, it can quickly and easily send clear monitoring images to the monitoring center.

Second, the application of high-speed ball in the field of intelligent transportation Application of high-speed ball in the field of intelligent traffic Omni-directional monitoring At present, high-speed high-speed ball cameras are installed in the main road sections of some cities. Because these cameras have a wide field of vision. Therefore, only one seat can enable the monitoring personnel to capture the ideal signal, which undoubtedly brings great convenience to the macro-management and regulation of traffic conditions. In addition, because most of the high-speed dome cameras now include technologies that automatically match the focal length and the rotational speed (autofocus), the dome can freely provide stable video effects regardless of whether it is rotating under large or small magnification. This also lays an important foundation for the evidence collection of traffic violation information.

Automatic scanning Due to the numerous and complex roads in many of today's major cities, traffic information is variable. Therefore, this has brought great difficulties to the management of road traffic. The intelligent high-speed dome camera can realize automatic switching of different video points in a fixed area. Users can set their own monitoring routes and speeds according to their needs, and make them operate in a circular manner, so that the camera device can also ensure its normal operation without any control. In this way, it is possible to avoid the loss of data due to lack of attention and to provide great protection for the integrity of traffic data.

High-speed dome camera alarm and grooming automatic alarm For the camera violation of the phenomenon of traffic, intelligent high-speed dome camera can be based on the pre-set to respond to relevant behavior, automatic shooting or alarm response. While dealing with illegal phenomena at the first time, it also reduced the workload of traffic managers.

Road condition monitoring and grooming At most intersections in Beijing's urban areas, control signals for traffic lights are often issued by nearby video surveillance equipment. These devices will determine the smoothness of the road based on the driving conditions of the vehicle being photographed, and send different instructions to nearby signals according to the traffic conditions to control the change of traffic lights nearby. In order to achieve the most efficient and reasonable road traffic results, the investment in transportation resources has been greatly reduced. Data shows that since the use of the intelligent traffic management model, the probability of traffic jams on the Beijing road has been reduced by about 20% compared with before. This had to make people feel that smart camera equipment has brought great contribution to traffic management.

Conclusion In summary, the intelligent high-speed dome camera has gradually become a mainstream device in the field of security monitoring with its advantages of high efficiency, intelligence, and clear and stable picture. Its high-speed, high-intelligence work features, as well as a wide field of vision and a variety of installation modes, make this type of camera equipment able to meet the monitoring work in many environments, and thus also be favored by many special industries. At present, with the development of related science and technology, the working ability of high-speed dome cameras is destined to follow the social needs and get rapid improvement and improvement. It is believed that in the next few years, intelligent high-speed dome cameras will eventually become an indispensable assistant in people's daily life and work, providing more complete protection for urban security.
