Abstract

The utility model discloses an LED (light emitting diode) visible light intelligent traffic network system, and belongs to the field of intelligent traffic systems. The LED visible light intelligent traffic network system comprises LED traffic lights, a light emitter and a light receiver, wherein the light receiver and the light emitter are installed on one vehicle; the light receiver on a back vehicle receives a signal sent by the light emitter on a front vehicle; signals sent by the LED traffic lights comprise a road condition and traffic lamp conditions; the signal sent by the light emitter comprises a distance between the front vehicle and the rear vehicle and a warning signal; and the light receiver receives the signals sent by the LED traffic lights and the light emitter. Due to the method, a visible light intelligent traffic network is formed, so that road condition information, the distance between the front vehicle and the rear vehicle, the warning signal and the traffic light conditions which are sent by the LED traffic lights can be received timely; and therefore, the traffic safety is guaranteed, and the probability of traffic accidents is reduced.

Description

LED visible light intelligent transportation network system

Technical field

The utility model relates to the intelligent transport technology field, particularly relates to a kind of LED visible light intelligent transportation network system.

Background technology

At present, replace incandescent lamp by ultra-bright LED, be used for traffic lights, warning lamp, identification light all over the world, compare with incandescent lamp, the advantage of LED traffic lights is that visibility is good, little power consumption, low calorie, long service life, reaction are fast, and can increase substantially brightness, become the perfect light source of future transportation signal lamp.

In existing intelligent transportation system, by at automotive front and side radar or infrared detecting set being installed, thereby be used for judging the distance between car and the barrier, in case of emergency, the vehicle mounted electric brain-capacity in time gives the alarm or self-braking is dodged, and regulates road speed according to road conditions oneself.Radar is to utilize target that target is found in electromagnetic reflection and measure its position, relative velocity, and its detection range is far away, and reliable, performance is subjected to the impact of weather less, but cost is too expensive, and can't accurately work under the traffic environment of complexity; Infrared acquisition is that the infrared radiation signal with incident is transformed into electric signal output, infrared radiation is the electromagnetic wave of wavelength between visible light and microwave, have that environmental suitability is strong, good concealment, volume characteristics little, lightweight, low in energy consumption, but easily be subjected to various thermals source, sunlight source disturb and penetration power poor.

The utility model content

The technical matters that the utility model mainly solves provides a kind of LED visible light intelligent transportation network system, can form visible light intelligent transportation network, receive in time traffic information, the distance between the vehicle of front and back, alarm signal and traffic lights situation that the LED traffic lights sends, guarantee traffic safety, reduced the probability that traffic hazard occurs.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of LED visible light intelligent transportation network system is provided, comprise: the LED traffic lights, optical sender, and photoreceiver, described photoreceiver and optical sender are installed on the vehicle, the photoreceiver of a next automobile receives the signal that the vehicle glazing transmitter in front sends, comprise road conditions situation and traffic lights situation in the signal that sends in the described LED traffic lights, distance and alarm signal before and after comprising in the signal that described optical sender sends between vehicle, described photoreceiver receives the LED traffic lights, the signal that optical sender sends.

In preferred embodiment of the utility model, described LED traffic lights and optical sender include: controller, modulator, driver and LED lamp, described modulator receives the coded data that described controller sends and the level signal that converts thereof into particular form, described driver drives LED lamp is luminous, converts the electrical signal to light signal and sends.

In preferred embodiment of the utility model, described photoreceiver comprises: photoelectric sensor, demodulator circuit and signal output apparatus, described photoelectric sensor converts the light signal that receives to electric signal and is exported by signal output apparatus after the demodulator circuit demodulation.

The beneficial effects of the utility model are: the utility model adopts LED to realize wireless visible light communication, has advantages of that network structure is simple, cost is low, practical, power consumption is little.
