Thus, in other implementations of the present invention, other components may be used without departing from the spirit and scope of the present invention. In addition, each component may be implemented solely by hardware or software configuration, but may be implemented by a combination of various hardware and software configurations performing the same function. Also, two or more components may be implemented together by one hardware or software.

Also, the expression " comprising " is intended to merely denote that such elements are present as an expression of " open ", and should not be understood to exclude additional elements.

1 is a view illustrating a vehicle stop line display system according to an embodiment of the present invention.

Referring to FIG. 1, a vehicle stop line display system includes a traffic signal controller 100, a stop line alert 200, and a detector 300.

The traffic signal controller 100 is a device for controlling a pedestrian signal lamp and a vehicle signal lamp. A pedestrian traffic light is a traffic light for a pedestrian walking on a pedestrian crossing, and a traffic light for a vehicle is a traffic light for driving the vehicle.

The traffic signal controller 100 transmits the traffic signal status information to the stop line notifier 200. Here, the traffic signal status information is information on which traffic signal is displayed on the current traffic light, and information on whether or not each signal indicating red, yellow, green, or left turn is turned on .

The stop line announcement device 200 is installed on the road along the vehicle stop line 10 before entering the crosswalk and the intersection by a method such as embedding or mounting. The vehicle stop line 10 is a position line set so that the vehicle stops at a position before the crosswalk in the pedestrian crossing signal.

The stop line notifier 200 provides a traffic signal to the driver through an optical display device such as an LED or sound according to the traffic signal status information transmitted from the traffic signal controller 100 and the external brightness.

That is, when the traffic signal state information indicates that the vehicle is temporarily stopped, and the external brightness is equal to or less than a predetermined reference brightness, the stop line announcer 200 lights the optical display device (for example, LED) (Vehicle suspension). The information indicating that the traffic signal state information indicates the vehicle stoppage may be information set to stop the vehicle such as a case where a red signal is lighted on a vehicle signal light and a left turn signal is turned on simultaneously with a red signal.

In addition, the stop-line notifier 200 detects the first vehicle approaching a predetermined distance when the traffic signal status information indicates that the vehicle is temporarily stopped, and when the external brightness exceeds the reference brightness, And sends a stop line notification signal to the terminal device. The terminal receiving the stop line notification signal can transmit a sound such as 'Stop before a few meters ahead of the stop line' or display a notification signal through the in-vehicle video display means. At this time, if the detected vehicle does not have a terminal device capable of short-distance communication, the stop line notifier 200 can inform the driver of the stop of the vehicle by lighting the optical display device (for example, LED). Here, the terminal device of the vehicle is a terminal device capable of short-range wireless communication, and may include audio of a vehicle, a terminal device (for example, a cellular phone, a DMB, a telematics, etc.) carried by a user, and the like.

For example, if the traffic signal status information is a red signal and the external brightness is less than the predetermined reference brightness, the stop line announcer 200 determines that the time is dark and informs the driver of the stoppage by lighting the optical display device. If the traffic signal state information is a red signal and the external brightness exceeds the reference brightness, the stop line notifier 200 determines that it is a bright time, and transmits a stop line notification signal to the terminal of the first vehicle approaching a predetermined distance And notifies the driver of the pause.

As described above, since the stop line informer 200 is bright during the daytime, the traffic signal can be informed in advance by using the sound, and the traffic signal can be informed in advance by using the optical display device such as LED because it is dark at night. In addition, the stop line announcer 200 may drive the sound and the optical display device together to inform the traffic signal in advance.

A yellow signal of a signal lamp for notifying the stop of the vehicle or a driver of a vehicle running by the stop line signal reminder 200 when the red signal is generated causes the driver himself to feel the risk of accident, So that it can be stopped.

On the other hand, the stopper announcer 200 includes a receiving box (not shown) inserted into the groove of the bottom surface of the road, and a transparent cover member (not shown) attached to the upper side of the receiving box.

The receiving box is formed of a metal material so as to have a predetermined rigidity, and is formed into a box-like box shape having an open top. An optical display, a brightness measuring unit, a communication unit, and a printed circuit board (PCB) assembly may be incorporated in the receiving box. At this time, the printed circuit board assembly functions as a control unit.

The transparent cover member to be bonded to the upper part of the receiving box preferably uses transparent tempered glass and is finished with a reinforced pair glass so as to smoothly illuminate the light and serve also as a lid.

A detailed description of the stop line announcer 200 will be given with reference to FIG.

The detector 300 is installed at both ends of the vehicle stop line 10 to detect whether or not the vehicle is stopped by the vehicle stop line 10 and to output a warning sound when the vehicle stop line 10 is touched. At this time, the detector 300 may be a laser detector or the like.

Both ends of the vehicle stop line 10 where the detector 300 is installed can be a point where the center line of the vehicle stop line 10 intersects with the vehicle and a point where the vehicle stop line 10 crosses the right side cargo.

The traffic controller 100, the stop line notifier 200, and the detector 300 communicate via a communication network. Here, the communication network may include a wireless communication network, a wired communication network, a local communication network, and the like.

2 is a block diagram schematically showing the configuration of a stop line alarm device according to an embodiment of the present invention.

2, the stop line notifier 200 includes a communication unit 210, at least one optical display device 220, a brightness measuring unit 230, and a control unit 240.

The communication unit 210 receives the traffic signal status information from the traffic signal controller and transmits a stop line notification signal to the terminal device of the vehicle. The communication unit 210 is a communication unit that interconnects a traffic signal controller or a terminal device through a communication network. The communication unit 210 includes a wireless communication module such as mobile communication and satellite communication, a wired communication module such as the Internet, And the like.

The optical display device 220 is electrically connected to the control unit of the ordinary traffic signal controller in the ground between the vehicle stop lines and is connected to a traffic light such as a traffic light on a road or a traffic light on the road, A plurality of LED modules are installed at predetermined intervals according to the design. Here, the optical display device 220 is described as an LED, but the optical display device 220 may be implemented by various devices that can be turned on or off like an LED.

The optical display device 220 is turned on when the traffic light on the crosswalk is illuminated in a blue color for pedestrians to pass, and when the external brightness is lower than a predetermined reference brightness, the optical display device 220 informs the driver in advance of a traffic signal of vehicle stoppage.

The brightness measuring unit 230 measures the external brightness. The brightness measuring unit 230 may be implemented by various apparatuses for measuring the brightness, such as an illuminance sensor.

The control unit 240 controls the lighting of the optical display device or controls the transmission of the stop line announcement signal according to the traffic signal status information from the communication unit 210 and the brightness measured by the brightness measurement unit 230.

That is, the control unit 240 informs the driver of the traffic signal of the vehicle stop by lighting the optical display unit 220 when the traffic signal status information indicates the pause. When the external brightness exceeds the reference brightness, the control unit 240 detects the first vehicle approaching a predetermined distance, and transmits the detected traffic light to the terminal device of the detected vehicle And transmits the stop line notification signal through the communication unit 210.

The control unit 240 controls the operation of various components of the stop signal reminder 200 including the communication unit 210, the optical display device 220, and the brightness measuring unit 230.
