≪ Desc / Clms Page number 1 > Apparatus for controlling crosswalk light and operating method thereof <

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a pedestrian traffic light control apparatus and a method of operating the pedestrian traffic light control apparatus, and more particularly, And a method of operating the same.

Crosswalks or pedestrian crossings for pedestrians are installed on the roads. Pedestrian traffic lights are installed on both sides of the pedestrian crossings so that pedestrians can cross the roads. And an operator signal lamp for indicating the signal state is installed.

Further, it is general that a signal controller for controlling the pedestrian signal lamp and the driver signal is installed around the pedestrian crossing.

The driver recognizes the display state of the driver's signal lamp to advance or stop the vehicle, and the pedestrian located on the pedestrian crossing recognizes the display state of the pedestrian signal light and crosses the crosswalk or waits.

The driver signal light according to the prior art may not recognize the displayed state due to overlapping with sunlight or neglect of the driver's attention.

Further, even when the pedestrian is walking, the vehicle does not have a function of monitoring or restricting a case in which the driver slowly feels anxiety to the pedestrian by moving the vehicle slowly.

On the other hand, the School Zone, which is a child protection zone that protects children around the school, is designated and operated. School Zone designates school districts within a radius of 300 m from elementary schools and kindergarten front doors as a protected area. Traffic safety facilities and road accessories are installed to secure students' safe areas to prevent traffic accidents.

Children attending elementary schools and kindergartens can not wait for a relatively long time. They move quickly and behave only in front of them. If the traffic lights change, they can cause accidents by crossing the crosswalk without checking the directions to the right and left.

Korean Patent Laid-Open Publication No. 10-2004-0002374 (2004.01.07), "Crosswalk warning and illumination device" according to the prior art partially solves this problem by installing a warning light signal generating device on a crosswalk So that the driver can recognize the pedestrian more easily.

1 is a functional block diagram illustrating a crosswalk signal lamp apparatus according to an embodiment of the prior art.

In the following, with reference to the accompanying drawings, a detailed description will be given of a pillar 5 installed on the road side of the road where the crosswalk is located, a transverse bar 7 extending toward the road from the top of the pillar 5, A warning light generating means 15 installed to face the road side at a central portion of the column 5 to emit warning light toward the light emitted from the illumination lamp 10, a plurality of illumination lights 10 for illuminating the downward crosswalk, , And a control unit (20) for controlling the illumination light (10) and the warning light generating means (15).

The pedestrian traffic light device according to the related art controls the warning light generating means 15 to send a warning signal to the driver merely raises a warning to the driver and has a problem that the driver's cognitive ability depends on the safety of the pedestrian.

In addition, when the pedestrian traffic light on the pedestrian crossing flashes, many drivers feel the anxiety of the pedestrian by moving the vehicle slowly regardless of the pedestrian. However, the pedestrian traffic light device according to the prior art does not have a special device There is a need to develop a technology that can alert the driver and safeguard pedestrians.

The signal lamp control unit 300 receives a signal indicating that the pedestrian has entered the waiting position of the pedestrian in the sensor unit 200 and receives a corresponding signal from the pedestrian signal lamp for a predetermined first time 130 of the vehicle.

The traffic light controller 300 blocks or ignores the pedestrian detection signal input from the sensor unit 200 for the second time set after the end of the first time and controls the pedestrian traffic light 130 to display a state in which the crossing can not be crossed .

That is, when the signal lamp control unit 300 detects that the pedestrian has entered the pedestrian waiting position in the sensor unit 200, the signal lamp control unit 300 displays the pedestrian's walking light signal in the signal lamp of the pedestrian crossing during the first time set so that the pedestrian can cross the crosswalk And controls the pedestrian signal lamp 130 so as not to output the pedestrian crossing signal even if it detects that the pedestrian has entered the pedestrian waiting position for a predetermined second time after the end of the first time.

The traffic light control unit 300 may calculate the first time by adding a predetermined margin time or a safety time to a value obtained by dividing the distance of the pedestrian crossing by the average walking speed value of a general person.

In addition, the traffic light control unit 300 may calculate a second time that is varied in proportion to the traffic volume for each time period irradiated on the road where the pedestrian crossing is installed, to an arbitrary value so that the walking signal is displayed excessively repeatedly, .

The blocking unit 400 may be installed at a central position of the electric pole 110 or a position between a waist and a chest of a person and may be rotated or rotated on the road for a first time by a corresponding control signal of the signal lamp control unit 300 Blocks the passage of the vehicle, and turns or rotates to one end of the pedestrian waiting position for a second time period, thereby blocking the pedestrian's passage.

The drive motor may use any one or more selected from among an electric motor, an air pressure motor, Or by using a plurality of reduction gears.

The vehicle number recognizing unit 500 takes the vehicle number of the vehicle that passes through the crosswalk for the first time for ignoring the status displayed on the traffic light or the vehicle signal lamp 135 by the corresponding control signal of the traffic light control unit 300 .

The vehicle number recognizing unit 500 includes a first photographing unit 510 for repeatedly photographing the front plate of the vehicle passing through the crosswalk repeatedly at least twice, a rear plate of the vehicle passing through the crosswalk at least twice A second photographing unit 520 for photographing repeatedly, images of images photographed by the first photographing unit and the second photographing unit are recorded on a license plate using digital image processing (DSP) A license plate recognizing unit 530 for recognizing the car number, an error in which the recognized car number is not the same among the two or more images captured by the first and second photographing units and the difference is generated , At least two images captured by the first image capturing unit are analyzed to solve the problem or at least two images captured by the second capturing unit are combined to recover the error, An error restoration unit 540 for restoring an error by combining at least two images photographed by the second photographing unit, a license plate of the vehicle, and a video to be a proof time and a proof image to a signal violation server of the police agency through a dedicated communication line or a general public communication line And a communication unit 550 for transmitting the data through wired or wireless communication.

In one embodiment, when two or more images captured by the first photographing unit are analyzed and recognized differently from "80max 13XX" and "XXmax 1318", the error reconstructing unit 540 synthesizes the two images, 1318 ", it is possible to derive the vehicle number of the vehicle that violates the traffic lights illegally. In such cases, it is reasonable to apply the majority rule.

Also, even when there is a difference between the images captured by the first and second photographing units, the error restoring unit 540 can correctly derive the license plate of the offending vehicle through the synthesis process by the majority vote.

When the illuminance of the pedestrian crossing is lower than the reference illuminance by the corresponding control and monitoring of the traffic light control unit 300, the illumination control unit 600 controls the lighting apparatus embedded in the pedestrian crossing so that the illuminance of the pedestrian crossing is controlled to the first illuminance If the vehicle is approaching the crosswalk at a speed higher than the predetermined speed, the controller controls the illuminance of the crosswalk to be a second illuminance that is brighter than the first illuminance.

<How to Operate Pedestrian Traffic Light>

A method of operating a pedestrian crossing signal lamp according to the present invention is a method in which a traffic light control unit constituting a pedestrian crossing signal lamp control unit detects an ultrasonic signal at a pedestrian waiting position by detecting the presence of a pedestrian (S1010) A change in output of the sensor, an output change of an infrared sensor which is installed on the front of a pedestrian signal and outputs an infrared signal to a pedestrian waiting position to detect whether or not there is a pedestrian (S1020) In step S1100, the pedestrian entering the pedestrian waiting position is detected based on the result of the weight sensor detecting the presence or absence of the pedestrian.

At this time, the first time is calculated by adding the predetermined safety time to the value obtained by dividing the distance of the pedestrian crossing by the walking speed, the second time is calculated so as to be changed in proportion to the traffic volume by the time zone of the road where the crosswalk is installed, When the pedestrian senses that the pedestrian has entered the position, the pedestrian signal is blinked to the pedestrian signal lamp for the first time set so that the pedestrian can cross the pedestrian crossing, and the pedestrian detection signal is blocked during the second time which is a predetermined time after the first time And controls the signal lamp so that a signal indicating that the pedestrian signal can not be walked is turned on or outputted.

Next, if a pedestrian is detected, it is determined whether a second time has elapsed (S1200). The second time is measured from the end of the first time, and the second time can be arbitrarily calculated based on the traffic volume per hour so that the flow of the vehicle is not interrupted too often.

Next, when the second time has elapsed, the walking signal is turned on to the pedestrian signal lamp (S1300), and the blocking part installed on the pole is rotated on the road for the first time to block the vehicle from passing (S1400).

The traffic light control unit, the blocking unit, the vehicle number recognizing unit, and the lighting control unit can display the pedestrian crosswalk at the pedestrian waiting position from the walking button provided on the front of the walker even within the second time To be output.

If the illuminance of the pedestrian crossing is below the reference illuminance, the illuminating device embedded in the pedestrian crossing should be controlled so that the illuminance of the pedestrian crossing becomes the preset first illuminance. (Step S1500), the illuminance output from the illuminator of the pedestrian crossing is controlled to be a second illuminance that is brighter than the first illuminance.

The front plate of the vehicle passing through the crosswalk during the first time is repeated at least twice to capture a plurality of frame images to secure the first image and to make the rear plate of the vehicle pass through the crosswalk at least twice And repeatedly capturing an image of a plurality of frames to secure a second image.

When license plate information of the vehicle is recognized by using the first image and the second image, and when a difference occurs in license plate information recognized from the first image and the second image, at least two images photographed by the first photographing unit are combined Or restores an error by combining at least two images photographed by the second photographing unit, or combines at least two images photographed by the first photographing unit and the second photographing unit to reconstruct an error The license plate information of the vehicle, the time of the violation, the place of the violation, and the video image for the proof are transmitted to the signal violation server of the police agency (S1600).

Further, even when there is a difference between the images taken by the first photographing unit for photographing the front plate of the vehicle and the second photographing unit for photographing the rear plate of the vehicle, the license plates of the offending vehicles can be accurately derived through the above- . It is natural that the majority rule applies to this synthesis process.

When the first time period ends (S1700), the blocking portion is rotated in the crosswalk direction so that the vehicle can pass, and blocks the pedestrian from crossing the pedestrian crossing.

It will be understood by those skilled in the art that the present invention can be embodied in other specific forms without departing from the spirit or essential characteristics thereof.

Therefore, it should be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
