LED display technology on highways

1. Variable information board and variable speed limit sign

The variable information board and the variable speed limit sign are released as important information of the intelligent transportation system. The computer of the monitoring center performs remote control through the communication network to transmit and display various graphic and text information. To promptly release different road conditions and various types of traffic information on different road sections to the driver, and carry out traffic regulations and publicity of traffic knowledge to reduce the reproducible obstruction of expressways, reduce the impact of non-recurring accidents on expressways, and improve driving safety; Thereby effectively diverting traffic and improving the efficiency of highway use. It can be used on highways and general roads, especially those controlled by highway entrances and exits.

The composition of the system: the variable information board and the variable speed limit sign system are composed of the main monitoring computer, the communication network converter, the display screen, the control card and the built-in control system, the chassis, the frame, the electrical protection and the lightning protection device, and the cable safety connection. Pieces, pairs of modems, power and signal engineering required for installation.

Second, the car screen (mobile traffic information screen)

The closure or reduction of the lane caused by road construction and maintenance is an early scheduled work for the competent highway departments and construction personnel, but it is still an unpredictable event for most road users, so the driver is informed through the traffic guidance screen. Or passers-by is very important. The fixed variable board report is limited by the non-fixed characteristics of the road construction site and is not easy to function. The vehicle screen (mobile traffic information screen) is a kind of variable feeling board, which is compact, flexible and suitable for direct installation. In the trailer-mounted truck, it can be placed directly on the target site anytime and anywhere to make up for the shortcomings of the fixed variable information board.

The composition of the system: the vehicle screen system is controlled by a computer, a control box, a display screen, a built-in control system, a chassis, a frame, a carrier, a solar battery, a battery, and a cable safety connector. During operation, the induction information can be downloaded to the display screen by the computer, or the commonly used induction information can be downloaded to the control box, and then the control box can transmit the data to the display screen. The latter is easy to carry in the general application, and the control box can also edit the text. The information is downloaded to the display.

Third, the guide card

In order to ensure the safety of construction workers and vehicles on the expressway, and also to protect the safety of personnel and vehicles using highways, traffic safety management departments require that highway vehicles must be equipped with eye-catching signs to warn and guide follow-up Vehicles to avoid accidents. The guiding warning sign is the necessary equipment for the construction work on the expressway.

Only by fully considering the warning signs designed and manufactured at the above points, can it be regarded as a warning sign that meets the requirements of the times.

DC cable connector diameter (d) is 2.1mm, diameter (D) is 5.5mm, thickness (B) is 10mm.
