Problems solved by technology

[0002] Pedestrian crosswalks are an important guarantee for pedestrians in road safety. Motor vehicles need to give way to pedestrians when they reach the crosswalk. However, in the evening or when the weather is bad, the lighting affects the visual resolution and response speed of many motor vehicle drivers. At this time prone to traffic accidents

Embodiment Construction

[0008] Such as figure 1 As shown, the present invention includes an infrared induction detector module, an LED lamp and an optical fiber module, and the data output end of the infrared induction detector module is connected to the data input end of the LED lamp and the optical fiber module.

[0009] The infrared sensor detector module works by detecting the infrared rays emitted by the human body. Once a person enters the detection area, it can detect the existence or movement of the human body and send the detection signal to the LED light.

[0010] The LED lamp and the optical fiber module are pre-buried under the crosswalk. When the LED lamp receives the detection signal from the infrared sensor detector, the LED lamp lights up, and the light emitted by the LED lamp propagates in the optical fiber to brighten the optical fiber. A bright zebra crossing is displayed on the ground, and flashes are used to remind motor vehicles to pay attention to pedestrians and ensure their s...

Abstract

The invention provides a light-guide fiber intelligent prompt system for a pedestrian crosswalk and belongs to the fields of electronics, optics and the like. The system comprises an infrared induction detector module, an LED lamp and a light-guide fiber module, wherein the data output end of the infrared induction detector module is connected with the LED lamp and the data input end of the light-guide fiber module. The system has main functions that the pedestrian crosswalk is an important guarantee for pedestrians in road safety and motor vehicles need to yield to the pedestrians when reaching the pedestrian crosswalk; but due to nightfall or bad weather, light illumination influences the visual resolution factors and response speeds of a great number of motor vehicle drivers; light-guide fibers embedded into the pedestrian crosswalk are lightened by the LED lamp when a condition that the pedestrians pass through the pedestrian crosswalk is detected through an infrared induction detector under the circumstance that the light is dark; the motor vehicles are prompted to beware of pedestrians through flashing for guaranteeing that pedestrians can safely pass through the pedestrian crosswalk.

Description

technical field [0001] The invention belongs to the fields of electronics, optics, etc., relates to optical fibers, infrared induction detector devices and technology, and is applied to an optical fiber intelligent prompting system for pedestrian crossings. Background technique [0002] Pedestrian crosswalks are an important guarantee for pedestrians in road safety. Motor vehicles need to give way to pedestrians when they reach the crosswalk. However, in the evening or when the weather is bad, the lighting affects the visual resolution and response speed of many motor vehicle drivers. At this time Just very prone to traffic accidents. Contents of the invention [0003] In order to overcome the deficiencies of the above-mentioned prior art, the present invention provides a technology and device based on an optical fiber, an infrared sensing detector device and a technical application of an optical fiber intelligent prompting system for pedestrian crossings. The infrared se...
