New field of LED display applications: red light capture system

Obeying traffic regulations is related to the safety of motorists and pedestrians. It is the premise guarantee for the happy life of every family. However, due to the safety awareness and social morality of some people, dangerous situations such as red light and “ghost probe” still occur from time to time. It is unprepared. In order to regulate the traffic behavior of pedestrians and non-motor vehicles, Wuhan City, Hubei Province, recently installed three pedestrian red light automatic capture systems on the streets of Wuchang. Many pedestrians and drivers said that “capture artifacts” have certain warning functions.

Pedestrian and non-motor vehicle red light automatic capture system is not mysterious. It has already started piloting in Shijiazhuang and other places, mainly composed of many large angles, such as shooting head, voice prompt system and display large screen. If the pedestrian or non-motor vehicle owner does not obey the traffic rules, the camera will record the entire process. When the signal light turns into a red light, if a pedestrian crosses the waiting area, the system captures the first photo and simultaneously gives a voice reminder to promptly return to the waiting area; if the pedestrian does not care about the voice reminder, when walking to the middle of the zebra crossing and continuing to move forward, The second and third photos were captured; the fourth photo was a close-up of the red light, showing the full picture. It may be that when pedestrians smashed the red light and sneaked up, they inadvertently looked up and found that their unethical behavior had been magnified and widely publicized. The resulting shame caused us to pay more attention to our words and deeds.

The pedestrian red light capture system is another application of the big screen. It is necessary to clearly display the distinguishing characteristics of each pedestrian so that it can really serve as a warning. Compared with traditional LCD and DLP splicing walls, led large screens can achieve higher display accuracy and better color reproduction, and are excellent in dustproof and waterproof performance, especially suitable for traffic roads with complex environments. In addition, the current small-pitch LED display has made breakthroughs in outdoor applications, which helps to improve the screen effect of the red light capture system.
