The features of the components of each recognition device are the same. Accordingly, only the control configuration of the first recognition device 410 will be described by way of example.

The recognition unit 411 recognizes the terminal 200, and when the terminal 200 is recognized, detects the received signal strength RSSI of the terminal 200 and transmits the detected received signal strength to the controller 412.

The control unit 412 controls the transmission of the received signal strength of the terminal 200, the identification number of the terminal 200, and its own identification number stored in advance.

The communication unit 413 transmits the received signal strength of the terminal, the identification number of the terminal, and its own stored identification number to the notification device 510 in response to a command from the controller.

The features of the components of each notification device are the same. Accordingly, only the control configuration of the notification device 510 will be described by way of example.

When the information of the terminal and its identification number are transmitted from the recognition device 410, the second communication unit 513a transmits the information to the second control unit 513b.

The second communication unit 513a communicates with the server 300 and, if there is a possibility of an accident, transmits the information on the likelihood of occurrence of the accident and its preset location to the server 300 in response to a command of the controller 513b. .

 The control unit 513b checks which recognition device information is received from the terminal received through the second communication unit 513a based on the identification number of the recognition device received by the second communication unit 513a, and checks the identified recognition. Check whether the information of the same terminal is received from the recognition device located in the same direction as the device.

That is, when the information of the terminal is transmitted from the first recognition device 410, the controller 513b checks whether the information of the terminal having the same identification number is transmitted from the second recognition device 420.

In this case, when the information of the terminal having the same identification number is received from the second recognition device 420 located in the same direction, the controller 513b determines the area where the terminal is located as the first area, and corresponds to the determined first area. The care level is checked and the output of the notification information corresponding to the checked care level is controlled.

That is, the controller 513b controls the lighting of the traffic light of the display 512 or the output of the announcement regarding whether the crosswalk is crossed through the speaker 514.

If the information of the terminal having the same identification number is not received from the second recognition device 420 located in the same direction, the controller 513b receives the transmission transmitted from the first recognition device 410 based on the information stored in the storage unit. Acquire the distance of the terminal 200 corresponding to the signal strength, determine the area where the terminal 200 is located based on the radius information and the acquired distance of the first recognition device 410, the care level of the determined area The control unit may determine the search result, search for notification information corresponding to the checked care level, and control driving of the display driver and the sound driver to output the searched notification information.

That is, the controller 513b checks the area where the terminal 200 is located, checks the care level corresponding to the second area if the location of the confirmed terminal 200 is the second area, and informs the corresponding care level. If the location of the checked terminal 300 is in the third area, the control unit outputs the information and checks the care level corresponding to the third area, and controls the output of the notification information corresponding to the checked care level.

When the distance of the terminal 200 is confirmed, the controller 513b counts a time for which the distance of the terminal 200 is kept constant, compares the counted time with a predetermined time, and if the counted time is longer than a predetermined time, the second communication unit. Incident occurrence notification information is transmitted to the server 300 through 513a.

If there is a pedestrian traffic light, the controller 513b checks the color of the light that is turned on at the pedestrian traffic light, and sounds when the pedestrian traffic light is red when the distance of the terminal 200 is close to the crosswalk. By controlling the driving of the driving unit 513e, the speaker 514 outputs a guiding message, 'Now it is a red light, do not cross the crosswalk', and the pedestrian with the distance of the terminal 200 approaching the crosswalk. If the traffic light is a green light, the sound driving unit 513e controls the driving of the speaker 514, and now the traffic light is crossing the crosswalk with the green light. Or 'Stop driving the vehicle' message.

The storage unit 514c stores the identification number and location for each recognition device, stores the distance for each received signal strength, stores the first and second radiuses r1 and r2, and stores the first and second radiuses r1 and r2. The plurality of areas set on the basis of the plurality of areas and the care level for each area are stored, and the notification information for each care level is stored.

That is, the storage unit 514c uses the second area of the area formed by the first radius r1 as the first area among the area formed by the first radius r1 as the first area. And a region between the outer region formed by the first radius r1 and the inner region formed by the second radius r2 as the third region.

At this time, the storage unit 514c stores different notification information for each care level, stores colors of different colors and different speeds for each care level, and stores different sounds for each care level.

More specifically, the first area is an area adjacent to the pedestrian crossing, and is an area in which the traffic weak is to be protected. When the traffic weakness is located in the first area, the first care level L1 is performed.

When the first care level L1 is performed, the traffic light of the display 512 turns on a red light and the speaker 514 outputs a stopment.

The second area is a radius area excluding the first area, which is likely to arrive at the crosswalk soon. When the traffic weakness is located in the second area, the second care level L2 is performed.

When the second care level L2 is performed, the traffic light of the display 512 turns on a yellow light and the speaker 514 outputs a slow comment.

The third area is an outer area of the radius, in which the traffic weak is located far from the crosswalk, but the traffic weak needs protection. If the traffic weak is located in the third area, the third care level L3 is performed.

When the third care level L3 is performed, the display 152 lights up a green light, and the speaker 154 outputs a comment to keep the speed limit.

The display driver 513d drives the display 120 in response to the command of the controller 513b, and the sound driver 513e drives the speaker 140 in response to the command of the controller 513b.

In this way, the visibility of the traffic lights is controlled or the speed limit is controlled based on the distance from the crosswalk to the traffic weak, and the sound output is controlled to alert the traffic weak or the driver. It is possible to induce safe driving of the car and to induce a safe crossing of the traffic weaker to prevent traffic accidents.

In addition, when the reception signal strength is transmitted from the recognition unit 411, the control unit 412 of the recognition device 410 determines the distance of the terminal 200 corresponding to the received reception signal strength based on previously stored distance information for each reception signal strength. The terminal acquires the location information of the terminal based on the acquired distance of the terminal and the previously stored location information of the terminal, and controls the transmission of the obtained location information of the terminal, the identification number of the terminal, and the previously stored identification number of the terminal.

In this case, the notification device 510 determines an area in which the terminal is located based on whether the recognition device 420 recognizes the same terminal, the length of the first and second radiuses of the recognition device 410, and the obtained distance. The control level of the area is checked, the notification information corresponding to the checked care level is searched, and the driving of the display driver and the sound driver is controlled to output the retrieved notification information.
