- Detail
Column type variable message sign is an important equipment of the traffic situation and traffic information released, it is the basic unit for displaying traffic information display device with LED light emitting device, display of graphics and text.according to the traffic, weather and command scheduling department instruction information,the operator can publish notifications and information to the variable message signs board, in order to effectively carry out induction on the traffic flow, improve the road network traffic capacity, traffic safety fast for the driver to provide quality services.
Product Features
● display module having the versatility and interchangeability can be composed of different display colors and different sizes according to needs.
● double-box structure, the formation of internal natural convection mode, so cabinets space temperature reaches equilibrium.
● pixel module junction box and use the "O" ring, with good moisture anti-leakage performance.
● module package uses advanced soft silicone, the elastic, strong anti-aging ability.
● power supply, it is important IC device through the heat sink cooling, not only solve the heat, but also to ensure the performance is unstable due to mechanical failure when the cooling fan caused.
● use special wide temperature range of the device, ensure the normal operation of the display at high or low temperatures.
● The control system only with the IPC, and higher reliability.
● use of sophisticated large-scale integrated chip high-speed serial transmission network alternative to discrete parallel transmission chip, reducing the complexity of the transmission display, reducing the complexity of the control system to improve the stability of the product.
● using the network cable to transmit data to reduce the screen body inside the transmission cable, greatly improve the stability of the display.
● using a common network data transmission technology, improve gradation display variable message signs, information boards enable a better display.
● using a common network data transmission technology, in favor of compatibility and product upgrading. Help to improve the response speed of the system variable message signs.
