Recognize the existence of. Specifically, since the user terminal 200 broadcasts its identification information at a set time, the first guide device AP1 receives the identification information of the user terminal 200 to detect the presence of the user terminal 200. Then, location information and guide information are transmitted to the detected user terminal 200.

In this case, the user terminal 200 automatically starts the guide by outputting the information received from the first guide device AP1 according to the setting, or outputs the received information according to the user's selection. For example, if the voice has entered the station XX. If you want the voice guidance, press the 'Shop' button on the terminal first. If the user presses the 'Shop' button, the guidance may be started. Here, the user terminal 200 compares the position information of the previous guide apparatus stored in the memory 110 with the position information of the first guide apparatus AP1 located in the subway station, whereby the user is located in the first guide apparatus AP1. It can be recognized that the XX station has entered.

When the guidance is started, voice information using the information from the first guidance apparatus AP1 is provided. For example, voice information is output to the voice output unit 240 of the user terminal 200. "The left direction is a ticket office. The straight direction is a ticket gate or a toilet."

When the user continues to go straight, the corresponding guide information is received again from the second guide device AP2 recognized next, and the user is provided with voice information using the information from the second guide device AP2. . In this case, as described above, since the previous guide device information, that is, the location information of the first guide device AP1 is stored in the memory 210 of the user terminal 200, the user terminal 200 moves straight from the user's location. It can be recognized that the direction is the toilet and the left direction is the ticket gate. Through this, voice information is output to the voice output unit 240, "the left direction is the ticket gate. The straight direction is the toilet." Here, if the user continues to go straight, the voice information “it is the entrance of the toilet” is output through the third guide device AP3, and when the user turns to the turnstile direction and enters the direction change zone, the user is installed in the direction change zone. The audio information is output via the fourth guide device AP4: "The left direction is the platform for A. The right direction is the platform for B."

When the user enters the platform A through the voice information, the voice information “The vehicle has entered the platform A toward the A” through the fifth guide device AP5 enters the platform B, and then through the sixth guide device AP6. The voice information "entering the platform B side" is output from the voice output unit 240, respectively.

As described above, according to the present invention, the guide information from the guide apparatus 100 installed in various places is transmitted to the user terminal 200, and the voice guidance is performed on the user terminal 200 itself, and the corresponding guide apparatus 100 is provided. By receiving the location information of the user, the user terminal 200 can recognize the walking direction of the user, it is possible to accurately guide the road.

5 is a view for explaining a voice guidance method in a place where the communication zones of the plurality of guide apparatuses 100 overlap.

In FIG. 5, three communication zones of the guide apparatus 100 overlap at a location of a user. In this case, the user terminal 200 receives all the information of the guide apparatus 100, and arranges the information, and sequentially outputs the position information of the guide apparatus 100. For example, the voice output unit 240 outputs a voice guidance, "a number of guide devices have been searched. Press a number for guidance. The number 1 is a ticket gate, the number 2 is a ticket office and the number 3 is a toilet."

In one embodiment, when the user presses the corresponding number of the user terminal 200, only the guide information of the corresponding number is output to the voice output unit 240 of the user terminal 200.

Meanwhile, in another embodiment, when the user presses the corresponding number of the user terminal 200, the voice guidance is output from the guide apparatus 100 of the corresponding number. That is, when the user presses the corresponding number of the user terminal 200, the voice guide request is transmitted to the guide device 100, and the guide device 100 receiving the voice guide request outputs the stored guide information as voice. To this end, the guide apparatus 100 may further include a voice output unit, and the guide apparatus 100 may output the same voice guide as in the user terminal 200 by using the own voice output unit. In this case, as the user terminal 200 recognizes the direction through the position information of the previous guide device 100 and the current guide device 100 stored in the memory 220, the current guide device 100 is a user terminal ( By comparing the location information of the previous guide device 100 transmitted from the 200 with its own location information, the direction of the corresponding user terminal 200 is recognized.

As described above, in the present invention, even when a plurality of guide devices 100 are densely installed, only the desired information can be selected and listened to, so that the accurate road guide can be provided. Since voice guidance through the device 100 is possible, an optimal guidance is possible according to the situation.
