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
The present invention belongs to the field such as electronics, optics, relates to light transmitting fiber, infrared induction detector device and technology, is applied to a kind of crossing light transmitting fiber intelligent prompt system.
Background technology
Crossing is the important leverage for pedestrian in road safety, motor vehicle needs, when arriving crossing, to give precedence to pedestrian, but during due to dusk or bad weather, light illumination has influence on vision addressability and the response speed of a lot of automobile driver, at this moment just very easily traffic hazard occurs.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the present invention is by providing a kind of technology and the device of applying a kind of crossing light transmitting fiber intelligent prompt system based on light transmitting fiber, infrared induction detector device and technology.Infrared induction detector module is by detecting the infrared ray of human-body emitting to carry out work, once people enters in search coverage, existence or the movement of human body just can being detected, and detection signal is sent to LED; Under LED and optical fiber module are embedded in crossing, when LED receives the detection signal from infrared induction detector, LED is lighted, the light that LED sends is propagated and light transmitting fiber is brightened in light transmitting fiber, demonstrate bright zebra stripes on the ground, carry out prompt machine motor-car by flash of light to watch for pedestrians, ensure its safety.
Hardware of the present invention is made up of infrared induction detector module, LED and optical fiber module.
Technical scheme of the present invention: comprise infrared induction detector module, LED and optical fiber module.The data output end of infrared induction detector module connects the data input pin of LED and optical fiber module.This device major function is that crossing is the important leverage for pedestrian in road safety, and motor vehicle needs, when arriving crossing, to give precedence to pedestrian.But during due to dusk or bad weather, light illumination has influence on vision addressability and the response speed of a lot of automobile driver, this device is detected when there being pedestrian by crossing by infrared induction detector when rather dark, and the light transmitting fiber be embedded under crossing is lighted by LED.Carry out prompt machine motor-car by flash of light to watch for pedestrians, ensure its safety.
The advantage that the present invention has: 1. simple to operate, it is unique to experience; 2. simple installation, compact.
Accompanying drawing explanation
Fig. 1 is block diagram of the present invention; Fig. 2 is configuration schematic diagram of the present invention.
Embodiment
As shown in Figure 1, the present invention includes infrared induction detector module, LED and optical fiber module, the data output end of infrared induction detector module connects the data input pin of LED and optical fiber module.
Described infrared induction detector module is by detecting the infrared ray of human-body emitting to carry out work, once people enters in search coverage, existence or the movement of human body just can being detected, and detection signal is sent to LED.
Under described LED and optical fiber module are embedded in crossing, when LED receives the detection signal from infrared induction detector, LED is lighted, the light that LED sends is propagated and light transmitting fiber is brightened in light transmitting fiber, demonstrate bright zebra stripes on the ground, carry out prompt machine motor-car by flash of light to watch for pedestrians, ensure its safety.
As shown in Figure 2, when in the search coverage that pedestrian 1 enters infrared induction detector 2, the infrared ray that pedestrian 1 self launches will be detected by infrared induction detector 2, thus infrared induction detector 2 just can detect existence or the movement of pedestrian 1, and detection signal is sent to LED 3, LED 3 and light transmitting fiber 4 are all embedded in crossing 5 times, when LED 3 receives the detection signal from infrared induction detector 2, LED3 will light, the light that LED 3 sends is totally reflected in light transmitting fiber 4, light transmitting fiber 4 is brightened, demonstrate bright zebra stripes on the ground, carry out prompt machine motor-car by flash of light to watch for pedestrians, ensure its safety.
Above one embodiment of the present of invention have been described in detail, but described content being only preferred embodiment of the present invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the present patent application scope change and improve, and all should still belong within patent covering scope of the present invention.
