Description

[0001] The present invention relates to a safety lighting apparatus for a pedestrian crosswalk,

The present invention relates to a pedestrian safety device, and more particularly, to a pedestrian safety device that improves the safety of a pedestrian passing through a pedestrian crossing.

In general, a pedestrian crossing road is displayed across the road so that pedestrians can safely cross the road on the road where the car is traveling, and a pedestrian traffic light is installed on a pedestrian crossing with a large amount of traffic and a lot of pedestrian crossings Pedestrians are able to cross the road safely.

As an example of a conventional lighting device, a lighting device is known as Registration Utility Model No. 20-0218044 so that a driver of a vehicle can identify the presence of a pedestrian crossing a pedestrian crossing in a night vision environment by concentrating the pedestrian crossing at night. Since such an illumination device for a pedestrian is applied to only one illumination lamp in one reflector, there is a problem that the illumination lamp can not be expanded in the reflector depending on the required brightness.

In addition, the street including the vicinity of the pedestrian crossing is provided with a street light which is lit at sunset and unlit for the day, so that a vehicle traveling on the road at night and a pedestrian crossing the road can safely run and walk. The brightness of the illumination is reduced due to various reasons, and the driver's field of view of the driving vehicle is confused, so that the identification is not easy.

In addition, the crosswalk light of the related art operates simply as a light illuminating only the pedestrian crossing, and there is a problem that the visibility of the driver is lowered when the light of the same color as that of the surrounding streetlight is irradiated. In addition, there was a problem of unnecessary power wastage due to illumination at a constant brightness even in the dark environment of the crosswalk lighting.

Unlike these crosswalks, crosswalks without traffic lights are installed and operated. In the case of a crosswalk without a traffic light, the driving vehicle must start after stopping, but these are ignored in the middle of the night. In view of this, a vehicle detection unit is installed in front of the crosswalk, (Japanese Patent Laid-Open No. 10-2006-0088433) has been proposed.

In this pedestrian crossing safety system, a lighting structure (illuminating column) provided with illumination lamps is provided above the crosswalk, and control means for controlling the vehicle sensing portion is provided on the side of the illumination column. When the vehicle passes through the vehicle sensing portion, And the illumination lamp is turned on for a predetermined time when the switch of the control unit is short-circuited. Thus, when the vehicle passes through the vehicle detection unit, the illumination lamp is turned on to brighten the area around the crosswalk, thereby preventing accidents.

In addition, crosswalks and roads have traffic signs for drivers that use various letters and symbols to guide the road situation. However, when various signs (such as condensation and gender) are formed on the signs, automobile headlights and indirect lighting There is a problem in that the driver can not easily recognize characters, symbols, figures, etc. displayed on the sign.

In recent years, there has been a system in which images are captured through an image captured through a CCD camera as well as converted into digital data to recognize the appearance of a pedestrian as a signal and turn it into a lighting signal. However, In particular, in order to compensate for the weakness of such a camera, a large number of cameras may be installed or a single camera may be used. A camera system is used in which a blind spot is eliminated and a rotating camera is used to convert the signal of the photographed image or a camera is operated at a distance to intensively photograph a suspicious region. However, the maintenance cost is high, There was also a problem of introducing expensive equipment.

In order to solve these problems, it has been demanded to improve the crosswalk lighting device to improve the visibility of various signs and to improve the lighting device for the safe walking of the pedestrian walking on the crosswalk.

Therefore, the pedestrians walking on the pedestrian crossing should be safe, pedestrian pedestrians should be easily recognized for the driver and elderly people, and the advanced pedestrian crossing lighting system and urban beauty should be improved. , The lighting of the crosswalk), and a crosswalk lighting device which greatly reduces the waste of electric power.

It is also intended to improve the visibility of traffic lights and traffic signs on the roads near the crosswalk, in the case of the main night, in the nighttime and in bad weather conditions, and to ensure that these signs will maintain the improved color of the main and night colors, , It is possible to supply the emergency power source and reduce the blackening phenomenon caused by the damage of the illumination lamp and the signboard, so that the traffic light, lighting means, signs installed on the pedestrian crossing can be illuminated by all lighting means on the crosswalk In order to improve the safety of pedestrians crossing the pedestrian crossing, it is necessary to improve the pedestrian sensing means to detect whether or not the pedestrian crossing has entered the pedestrian crossing. In addition to the known pedestrian sensing means, So that it is possible to detect the entrance Detecting the weight and it has been also required to talk more stable operation of the traffic lights, pedestrian crossing lighting means in the screen by the switching signal of the illumination means.

The pedestrian crossing safety device according to the present invention includes pedestrian crossing and pedestrian crossing pedestals located in the vicinity of a pedestrian crossing by installing pedestrian weight detecting part 140 and pedestrian presence detecting part 112 with a predetermined width in a crosswalk, And pedestrians who take their feet nearby.

That is, when the pedestrian approaches the vicinity of the crosswalk streetlight (when the pedestrian approaches the one side crosswalk), the pedestrian presence detection unit 112 and the pedestrian weight detection unit 140 detect the pedestrian, The illuminating unit 130 is lit by the set reference value of the illuminating unit 100 to illuminate the crosswalk and its surroundings.

Therefore, by detecting the weight of the pedestrian through the pedestrian weight detection unit 140 without detecting only the pedestrian presence detection unit 112 as a detection signal, it is possible to prevent the malfunction of the pedestrian sensing operation and to secure the safety of the pedestrian passing through the pedestrian crossing do.

That is, when the pedestrian approaches the pedestrian's periphery, pedestrian presence detection unit 112 and pedestrian weight detection unit 140 detect or sense the pedestrian and detect the pedestrian through LEDs of illumination unit 130 through control unit 100 and illumination driving unit 160 Not only the illumination lamp 132 but also the red light of the vehicle signal lamp is clarified and a warning sound is emitted to warn the driver of the traveling vehicle.

On the other hand, when the pedestrian approaching the pedestrian crossing pedestrian crossing is moved along the pedestrian crossing without crossing the pedestrian crossing and is out of the sensing range of the pedestrian presence detection unit 112 and the walking weight detection unit 140 installed on the pedestrian crossing ( And if it is not detected, operates the signal lamp for a predetermined time to turn off the illumination unit 130 which is turned on.

If the traffic lights are operating normally, the pedestrian presence detection unit 112 and the pedestrian weight detection unit 140 maintain the pedestrian for a normal period of time. The pedestrian safety device of the present invention can be operated not only in a normal operating signal system but also in an abnormal dynamic signaling system.

First, in addition to the signal system in normal operation that detects a pedestrian entering the pedestrian crossing and detecting a pedestrian through the pedestrian weight detection unit 140 in addition to the pedestrian presence detection unit 112 on the pedestrian crossing, It is possible to detect the presence of the warning signal and to enable emergency operation of the function by applying a switching signal to both the LED lighting lamp 132 and the speaker 135 in addition to the walking signal lamp 133 and the vehicle signal lamp 134. [

Particularly, the illumination on the crosswalk can be seen clearly and the alarm sound can be emitted, the driving vehicle signal lamp 134 can emit red light, and the LED lighting lamp 121 of the sign 120 can also emit clearly, It is safe to walk on the sidewalk as well as unauthorized pedestrians.

On the other hand, when the normal traffic light signal in the crosswalk is turned on in red, and the vehicle in operation runs in violation of the signal during normal signal operation, the vehicle entrance sensing unit 190 senses the signal. The sensed signal may be applied to the control unit 100 to generate a predetermined operation signal.

At this time, a warning sound is generated through the speaker 135 to notify the pedestrian that the pedestrian is entering the pedestrian crossing, and at the same time, the pedestrian is informed of the entry of the vehicle that is in violation of the signal. The LED illumination lamp 132 is also illuminated Thereby making it possible for the driver of the traveling vehicle to avoid the pedestrians in front of the pedestrian crossing.

When a vehicle traveling on the road is detected by the vehicle entry detection unit 190 approaching the crosswalk while the traffic lights are operating with the blinking light (yellow blinking), when there is no pedestrian on the crosswalk, When the pedestrian has completely passed the pedestrian crossing, a straight-line signal (green light) is turned on to illuminate the pedestrian's pedestrian crossing, To be controlled.

When the pedestrian passes through the pedestrian crossing, the pedestrian presence detection unit 112 and the pedestrian weight detection unit (not shown) 140), the traffic light operates in its original blinking (yellow blinking) state.

As described above, in the pedestrian crossing safety device according to the present invention, the detection signal and the detection signal of the pedestrian presence detection unit 112 installed on the pedestrian walkway as well as the pedestrian weight detection unit 140 can be detected by a pedestrian The pedestrian presence / absence detection signal and the weight detection signal are applied to the control unit 100. When the signals of the pedestrian presence detection unit 112 and the pedestrian weight detection unit 140 are simultaneously applied, The present invention provides a safe pedestrian crossing illuminator that can prevent errors in the presence / absence detection signal or prevent an error in weight detection by selecting a possible signal, thus ensuring the detection and detection of the pedestrian.
