This variable message sign uses high-brightness full-color LED modules with a resolution of 64*64 pixels, which can display text, symbols, and images, providing rich dynamic traffic information. The automatic brightness adjustment system can adjust the display brightness from 0 to 10000cd/㎡ according to ambient light intensity, ensuring clear recognition in strong sunlight (visibility up to 1500 meters) and energy saving at night. It supports multiple communication modes (4G/Wi-Fi/wired), allowing remote control and content update in 10 seconds, which is 10 times faster than traditional manual update signs. The 5mm thick aluminum alloy panel and IP68 waterproof rating make it suitable for harsh outdoor environments, and the 15-level wind resistance design ensures stability in extreme weather such as typhoons. Unlike single-color variable signs, this full-color display can use different colors to distinguish warning levels (red for danger, yellow for warning, green for guidance), improving the recognition efficiency of drivers by 40%. It also has a fault self-diagnosis function, automatically sending alarm information to the management platform when a fault occurs, reducing maintenance time and costs.
The sign has a display area size of 1280mm*1280mm, with a 5mm thick high-strength aluminum alloy substrate weighing 45kg, which is durable and corrosion-resistant. The full-color LED modules have a pixel pitch of 20mm, and the display resolution is 64*64 pixels, which can clearly display 16*16 dot matrix text and simple images. The maximum display brightness is 10000cd/㎡, ensuring clear recognition within 1500 meters in strong sunlight, and the minimum brightness is 500cd/㎡, avoiding glare affecting drivers at night. The product supports 4G/Wi-Fi/wired communication, with a data transmission speed of up to 100Mbps, realizing real-time content update. The wind resistance rating is grade 15 (166km/h), and the waterproof rating is IP68, which can be submerged in 2m deep water for 1 hour without damage. It has passed NEMA TS-1 expressway sign certification, FCC electromagnetic compatibility certification, and complies with GB 5768-2009 traffic sign specifications. The LED module has a service life of 100,000 hours, and the overall service life of the product is 20 years with proper maintenance.
This intelligent variable message sign is widely applied in expressways, urban ring roads, high-speed interchanges, and tunnel entrances, providing real-time traffic guidance and safety warnings. In expressways, it can display real-time speed limits, accident warnings, road closure notifications, and weather information (such as fog, ice), guiding drivers to adjust their driving strategies in time and reducing traffic congestion and accidents. In urban ring roads, it can display real-time traffic flow information and detour routes, improving urban traffic operation efficiency. For expressway management departments, its remote control function reduces the cost of on-site maintenance, and the fault self-diagnosis function improves the efficiency of fault handling. It is also suitable for large-scale activities and emergency rescue scenes, providing real-time traffic guidance for large numbers of vehicles. Additionally, it can be used in port logistics areas and airport access roads, guiding vehicle flow and improving transportation efficiency.
