Embodiment Construction

[0025] Under the condition of heavy fog and low visibility, the transmission loss of the light source of the traffic variable information board increases, so the transmission distance is much smaller than that under normal visibility conditions. Especially when the visibility is less than 100 meters or even lower, the effective visual distance of the variable information board is shortened, traffic information cannot be effectively released, and driving safety is seriously affected. Laser is a coherent light source, and LED is an incoherent light source. Compared with LED incoherent light source, laser has better beam directivity, and the beam can transmit farther under the same power condition, so laser can be used as traffic variable information panel light source. The only thing to pay attention to is the safety of the power of the light source to prevent it from affecting the human eye. Therefore, the output power of the laser light source needs to be automatically adjust...

Abstract

The invention provides a high-brightness traffic variable message sign and an implementation method thereof. The message sign comprises a traffic message display panel, a laser diode array, a power system, a light-emitting control system and a communication module, the laser diode array is composed of a plurality of laser diodes, emergent ends of the laser diodes are connected to preset light-emitting point positions on the traffic message display panel respectively through optical fibers, and the light-emitting control system acquires traffic information needing to be displayed through the communication module, outputs a control signal to the power system and respectively supplies power to the laser diodes. The high-brightness traffic variable message sign enables a power supply to be not directly exposed and is small in impact of outdoor temperature variation, thereby being longer in service life. Besides, the high-brightness traffic variable message sign is good in waterproofness, free of aging and soaking, concentrated in light beams, good in haze-penetrating property, high in system brightness, low in power consumption and capable of effectively displaying the traffic information under low-visibility conditions.

Description

technical field [0001] The invention belongs to the field of traffic information release and display, and in particular relates to a high-brightness traffic information board applied under low visibility conditions and a realization method thereof. Background technique [0002] Traffic Variable Message Sign (Variable Message Sign, VMS) is a kind of dynamic traffic sign board, which is usually arranged on traffic facilities such as intersections, bridges, tunnels, elevated roads, expressways, etc., to provide visible traffic guidance information display, used for Indicates information such as traffic conditions, road conditions and occasional events ahead of the driver. The traffic variable information board, together with the traffic information broadcast and the vehicle navigation system, has become an important means of traffic information release. [0003] The traffic variable information board can timely release different road conditions and various traffic information ...
