It is generally believed that intelligent transportation system is established in the road traffic infrastructure, urban public transport and road transport system, integrated information collection and processing, integration and exchange, analysis and control, and finally to the release of information as the goal of integration , Can achieve intelligent management of the transport system. The improvement of traffic management, transportation efficiency and traffic safety service level should be the target of intelligent transportation system construction. The realization process of this kind of goal will promote the change of traditional transportation industry to modern transportation service industry to a certain extent.
In the LED display technology related applications, for the public road traffic information display is one of the important application areas. In the way of public-oriented traffic-induced information release, the more common display and distribution information in daily life is road traffic induction screen, urban traffic guidance display screen, parking induction screen and road variable information sign. These different traffic-induced information dissemination methods, according to the relevant traffic road management requirements and the actual situation of road traffic information in real time.
The characteristics of intelligent transportation system
Intelligent transportation system is actually a road traffic information and communication system, its production and development is based on system integration, electronics, communications, information services and other different new technologies, has now penetrated and applied to aviation, water transport, rail transport, Urban traffic induction, highways, subway rail transportation in the field of new transport system. The construction of intelligent transportation system can not only improve the road network capacity and road traffic information service level, but also in the field of environmental protection, to promote the reduction of exhaust emissions and improve energy efficiency and so has a broad application prospects.
In the construction of intelligent transportation system, the construction and application of intelligent traffic information service system is the main content of the development of intelligent transportation field. The design and establishment of advanced transportation information service system for the public is the proper way of intelligent transportation system. Justice and development trend. For different types of transportation or different areas of transportation, intelligent transportation system to provide intelligent traffic information services will be focused and different.
Intelligent traffic information service system has many different transportation applications, including not only the variable information intelligence board for highway applications, variable speed limit signs, road access information service system, but also traffic guidance in urban transportation applications System, traffic management information integrated service system, road traffic information external release system.
In the field of intelligent transportation applications, the release of real-time traffic information of urban or road is the main form of intelligent traffic information service, that is, through a variety of information display equipment will be real-time traffic information display, most of the more common and common display Equipment, these display devices can include LED display, LCD display, DLP display and so on. With the continuous development of embedded technology, intelligent traffic information display system has developed into a functional scalable, multimedia technology, network connectivity integrated system.
LED display features
As the LED display technology continues to grow and develop, LED display equipment products in the field of intelligent traffic information display has been a very wide range of applications, has now become the mainstream of modern traffic information display. In the field of intelligent traffic information display, the corresponding traffic information display equipment products can be displayed according to the requirements of road traffic management and traffic guidance information in real time to display the current actual road traffic information, in which the LED display equipment products in the actual engineering application scene has the following characteristics :
(1) LED display with high brightness and reasonable viewing angle. Road traffic guidance information is mainly released for road traffic participants, the general situation for the driving vehicle, so the display of the product perspective is not demanding. In view of the fact that in the case of the front of the sun direct display, the display contents of the display product should be kept at a certain degree of visibility, and therefore the display product has a high brightness.
(2) LED display products can work without interruption, to adapt to different environmental conditions. As the traffic information induction LED display of the workplace are generally outdoor conditions, the relevant external environment is more complex and varied, should take into account the workplace of the highest temperature and minimum temperature, rainfall, environmental humidity, air quality and extreme weather and other aspects Environmental requirements, in order to maximize the stability of the traffic information to show the stability and reliability.
(3) LED display can be remote monitoring, intelligent detection. Due to the actual use of the scene needs, used to publish traffic information LED display installation location is usually distributed in a larger area, in this scenario, the general need for traffic management control center on the scene of a single LED display products Process monitoring. The use of remote control of the LED display for routine maintenance and environmental testing will be more convenient, but also save resources.
