Project requirements

In the information age and the rapid development of intelligent transportation system today, in the field of transportation, information release has become an important service content. Traffic guidance screen is mainly used in dense sections of urban roads and main trunk roads to present the overall road outline and provide drivers with the road direction ahead. As the driver's "eyes" on the road, LED traffic display plays a very important role. LED traffic guidance display works 24 hours a day, and the environmental illumination changes greatly, which requires that the brightness of the screen can be adjusted automatically according to the environmental illumination. As the LED traffic guidance display works under outdoor conditions, it is required that the display has a high level of protection to avoid the influence of temperature, rain, humidity, corrosion, lightning and other factors. In addition, in the structural design of LED traffic guidance display screen, we also need to pay attention to the problems of heat dissipation, waterproof, dust and so on.

Implementation effect

KW's LED traffic guidance display adopts advanced energy-saving circuit design, with temperature control and light control technology, which can automatically adjust the brightness according to the changes of the surrounding environment. This not only ensures that the traffic guidance display can be clearly visible at the maximum ambient illumination in the daytime, but also avoids the "glare" phenomenon in rainy days and nights, so that it can be used for driving unfamiliar with road conditions in any weather conditions It provides road information guidance; it has a large viewing angle, no dead angle, no color deviation, no distortion, clear display content, wide display coverage, which meets the visual distance of about 200m of traffic guidance display screen under normal conditions; it adopts redundant n + 1 backup power supply mode and hot loop backup communication system, which reduces the average failure rate to 1 / 100000 and greatly reduces the power supply difference The black screen phenomenon often leads to meets the requirements of LED traffic guidance display on system stability and reliability; the box structure design of kW LED traffic guidance display meets the requirements of IP65 protection level, and the module is treated with three proofing paint, which can still guarantee absolute protection under extreme adverse conditions such as outdoor strong typhoon weather and plum rain season, under strong wind and heavy rainfall erosion The guidance screen can clearly display the traffic dynamic situation, guide and dredge the traffic, and ensure the smooth road.
