The floor glare lighting 210 is preferably mounted in a plurality of longitudinal directions so that the vehicle driver can easily identify the crosswalk line to serve as a lighting. When the light is irradiated by changing the direction of irradiation by distance and angle from the bottom to the bottom of the road surface, good visibility lines may be generated. However, only one floor illuminating light 210 may be mounted in the embodiment of the present invention.

In the intelligent road boundary stone 110 according to the present invention, one surface on which the warning light 200 and the floor lighting lighting 210 are mounted is preferably faced to the road. On the other hand, the intelligent road boundary stone 110 may further include a warning device for driving at the same time as the warning light 200 or the floor lit lighting (210). The warning device may be used as a way to alert the vehicle driver.

In addition, the intelligent road boundary stone 110 is equipped with a human body sensor 220. The human body sensor 220 performs a function of detecting a person trying to enter the crosswalk in an embodiment of the present invention. When the human body sensor 220 detects a person, the beacon 200 and the floor lighting 210 may operate at the same time to simultaneously drive the pedestrian crossing safely and the vehicle driver safely.

In addition, the sensor road module 230 is mounted on the intelligent road boundary stone 110. The sensor node module 230 performs an intercommunication function between the intelligent road boundary stones 110 and transmits data to an intelligent street lamp 120 located nearby. The sensor node module 230 may be understood as a conventional sensor node concept used in a Ubiquitous Sensor Network (USN).

The intelligent road boundary stone 110 further includes a power control panel for controlling power inside, a storage battery and a logo, and an integrated controller for controlling the entire operation, and an internal environmental measurement sensor for measuring the internal environment such as temperature, humidity, and flooding. It can be provided.

The intelligent streetlight 120 shares information acquired by the intelligent road boundary stone 110 and transmits the information to the intelligent road boundary stone 110 on the opposite side, or transmits the information to a management server (not shown). The sink node module of the intelligent street light 120 may exchange information with the sensor node module 230 of the intelligent road boundary stone 110 and include environmental information and lighting control information.

Next, a crosswalk display method using the intelligent road boundary stone 110 will be described. 5 is a flowchart illustrating a pedestrian crossing display method using an intelligent road boundary stone according to a preferred embodiment of the present invention. A description with reference to FIG. 5 is as follows. In FIG. 5, a pedestrian crossing display method is divided into a case where there is no traffic light, a traffic light and a traffic light controller, and a traffic light and a traffic light controller.

1. No signal (A cycle)

When a person enters the crosswalk, the human body sensor 220 of the intelligent road boundary stone 110 recognizes a person who wants to walk the crosswalk (S_A1). Thereafter, the warning lamp 200 and the floor illumination lighting 210 are turned on (S_A2).

After a predetermined time has elapsed (that is, when a person has reached the center of the crosswalk), the sensor node module 230 requests the lighting of the intelligent road boundary 110 located at the opposite side (S_A3). In this case, the sensor node module 230 may perform the lighting request as soon as the warning lamp 200 and the floor lighting lighting 210 are turned on. The integrated controller 420 of the intelligent road boundary stone 110 located on the opposite side lights the beacon 200 and the floor illuminating light 210 upon receiving the request (S_A4).

The human body detecting sensor 220 provided in each intelligent road boundary stone 110 located at two opposite locations continuously performs a sensing function at predetermined time units (S_A5). In addition, the sensed value is shared with each other using the sensor node 230. If the two human body sensors 220 are no longer able to sense a person for a predetermined time, the warning lights 200 and the floor illuminating lights 210 on both sides are turned off (S_A6).

2. If you have a traffic light and use a traffic light controller (B cycle)

In general, in pedestrian crossings with traffic lights, people walk the crosswalk when the traffic light indicates a walking signal. When the traffic light indicates a walking signal, the traffic light controller recognizes a walking signal display fact of the traffic light and transmits the fact to the intelligent road boundary stone 110 (S_B1). At this time, the traffic light controller may use a photo sensor or a blue diode installed in the traffic light. The traffic light controller may recognize that the traffic light displays a walking signal when the photo sensor or the blue diode detects a walking signal such as a traffic light. Then, the warning light 200 and the floor illumination lighting 210 of the intelligent road boundary stone 110 is turned on (S_B2). Typically, the traffic lights are installed on both sides of the road, and in step S_B2, both intelligent road boundary lights 110 turn on the warning lamp 200 and the floor illumination light 210. If the traffic light is installed on only one side of the road, steps S_A3 and S_A4 may be performed in order.

Thereafter, when the traffic light controller acquires a walking prohibition signal from the traffic light, the traffic light controller transmits the fact to the intelligent road boundary stone 110 (S_B3). Then, the sensor node module 230 receives the fact, and the warning lamp 200 and the floor illuminating lamp 210 are turned off (S_B4).

3. If there is a traffic light and no traffic light controller is used (C cycle)

If the traffic light controller is not used, the walking signal display or the walking prohibition signal display of the traffic light is not known. In this case, a device for detecting a walking signal is installed in the traffic light. Then, the sensor node module 230 of the intelligent road boundary stone 110 formed on both sides can receive the signal detected from the photo sensor or the blue diode to detect the illuminance of the traffic light (S_C1). When the photo sensor or the blue diode detects blue at step S_C1, the warning lamp 200 and the floor illumination light 210 of the intelligent road boundary stone 110 are turned on (S_C2).

Subsequently, the sensor node module 230 detects a walking signal such as a traffic light in conjunction with a photo sensor or a blue diode installed in the traffic light at a predetermined time unit, and if the sensor node module 230 does not receive a detection signal for a predetermined time (S_C3). In operation S_C4, the warning lights 200 and the floor lighting lights 210 of the intelligent road boundary stone 110 are turned off.
