LED display has a wide range of applications in many areas of the social economy. Among the many application fields of LED display, the display of traffic information is one of the important application fields, especially the arrival of the information age, the development of intelligent transportation system, and the release of information becomes important in the transportation field serving the public. The service content and various types of information display equipment have become the leading means for the public to release information to the public by train stations, docks, bus stations, highways, urban roads, parking lots, etc. Among them, LED display with high brightness, high reliability, etc. Features are favored.
LED is one of the means of intelligent transportation system display
Intelligent Trans-portation System (ITS) refers to an intelligent information system that provides integrated traffic information services to the public or special audiences. The intelligent traffic information service system generally includes information sources, information processing, and information release display. The release display mainly uses various multimedia display devices, such as LED display, LCD display, CRT display, and PDP display. Wait.
The development of modern information display technology has formed a series of information display products such as CRT, LCD, PDP, LED, EL, DLP and so on. Throughout the development of various display products, LCD is dominant under 14 inches, CRT is dominant in 14 inches to 32 inches, 40 inches to 70 inches or even 100 inches will be the market for PDPs, more than 100 inches, whether indoors Or outdoor, LED display has become an mainstream product with absolute advantage.
In China's transportation industry, relatively speaking, the airport flight dynamic information display system is generally leading in terms of system composition and display terminal; the railway passenger guidance information display system starts relatively early, and the display means traditionally adopts LED and CRT as The main development has been rapid in recent years. The system is connected with the passenger transportation automation system and shows an excellent level of intelligence. The road traffic guidance system is rapidly emerging and is in the process of development and improvement. Due to the environmental characteristics of road traffic, LED display becomes the main information. Display means.
LED display is the main release carrier of road traffic guidance system
The road traffic guidance system is an important traffic information service system in the modern urban intelligent traffic management system. The system processes and analyzes the traffic dynamic status in real time. The command and decision makers of the control center publish and display traffic information through manual or automatic methods. Road conditions, etc., reduce the degree of blockage and improve road capacity.
In practice, traffic-inducing information for the public is generally released in an outdoor environment. Due to the high brightness characteristics of LED display, various forms of LED display become the main distribution carrier of traffic guidance information. Common traffic-induced LED display modes include traffic-induced LED display (variable information board), traffic-induced route display, parking signs, and variable signage.
Traffic guidance information outdoor LED display, according to the requirements of road traffic management and the actual situation of traffic guidance information release display, has the following characteristics in specific use functions: high brightness, reasonable viewing angle; display color is mainly red, green and yellow; Display brightness is automatically adjustable; all-weather work, complex environmental conditions; remote control, intelligent detection; high security, real-time, accuracy, reliability requirements.
LED display has broad prospects in the transportation field
With the continuous improvement of material technology, the application range of LED has been broadened. Looking forward to the application of LED display in the transportation field, there are several aspects worthy of attention:
Traffic signal market demand is strong
Ultra-bright, high-power LED devices have been widely used in urban traffic lights. LED signal lights are favored by urban traffic management departments for their high brightness, high reliability, low cost of use, and long life. From a nationwide perspective, the urbanization process and the development of road municipal construction, the number of new traffic intersections continues to increase, and the traditional traffic lights currently used are also replaced by LED signal lights. It is predicted that the domestic road LED traffic signal market capacity should be several billion yuan. In addition, road lane indicator lights, machine-taste railways, shipping and other fields of signal, marking lamps, there is also a large market potential.
Highway LED variable information boards and other standardized and standardized products
Highway LED variable information board, variable speed limit sign and other products have developed into standardized and standardized products in highway construction. The existing roads need to be supplemented and improved. New roads have requirements for standard and standard supporting facilities, and the industry standards for related products are also It has been officially released for implementation. It is estimated that the market capacity of display products such as highway variable information boards and variable speed limit signs will be between 300 million yuan and 500 million yuan per year.
Broad application prospects in the automotive field
According to research statistics, the response time of LEDs used as the main brake lights of automobiles is 80 ns faster than that of traditional incandescent lamps, and the safety distance of 4 to 6 meters is increased on the highway. Due to the good seismic performance, power saving, and environmental protection of LEDs, the application of automotive lighting and lighting will also develop well. At present, many brands of automobile manufacturers at home and abroad have begun to adopt LED brake lights, instrument lights and lighting.
Urban road traffic guidance, signs, etc. are gradually expanding
Road traffic-induced LED display is growing rapidly in various cities, and product technology is developing rapidly. In terms of product types, traffic-induced LED displays are still mainstream products, but various simple, economical and practical variable traffic information signage products will be popularized and dominated.
Beijing 2008 Olympic Games, Shanghai 2010 World Expo will bring development opportunities
The 2008 Beijing Olympic Games and the 2010 Shanghai World Expo will bring huge business opportunities for LED display. In the field of urban transportation, the market for LED display will increase significantly.
