Intelligent direction of LED traffic display
With the popularization of outdoor LED electronic large screens, LED traffic displays also play an indispensable role in people’s lives. Roadside signs, road condition descriptions, and road cultural construction are all inseparable from it. At present, the LED display screen is developing in the direction of intelligence and standardization in the field of transportation, which is undoubtedly a good development opportunity for the LED screen industry. So how to perfect and improve the LED traffic display? There are two aspects to improve the outdoor LED traffic screen:
1. The product quality of LED traffic screen. In the production of LED display, some low-end and middle-end enterprises do not hesitate to reduce the price of the display to participate in the competition in order to gain market share, which results in poor product quality. As a result, the brightness of some LED traffic displays on the road is not properly set, resulting in “light pollution”. The sun is not clear during the day, and the light is too bright and dazzling at night. The traffic induction effect of such products has caused strong dissatisfaction. Therefore, LED display companies should pay attention to the improvement of product quality and strictly control, and good products will be deeply loved by the majority of users.
2. Traffic communication protocol standards. Due to the lack of traffic communication protocol standards, the products produced by some LED display manufacturers have many problems, and at the same time, it also affects the development of the LED display industry to a certain extent. In order to make the various subsystems of the transportation system operate in a coordinated and efficient manner, it is necessary to establish an efficient communication network system to realize the heavy and close communication within the system. Informationization of traffic is an important part of Intelligent Transportation System (ITS). At present, the communication protocol standard applied to intelligent transportation in my country is still in the process of formulation. If a unified, open and sustainable communication standard is not established in time, it will lead to waste of investment, failure of coupling of various systems, and inability of each part to be efficient. coordination and other issues. The standard unification of traffic protocols is closely related to system integrators and display manufacturers, so the establishment of national-level unified standards will help the development of the LED traffic display industry.
