As shown in the figure, the wireless communication-based public transportation information guidance system using a mobile terminal according to the present invention starts by executing a public transportation information guidance program (S10).

Here, before executing the present program, the user is equipped with a station information receiving apparatus capable of receiving information of each station, so that the user can set a criterion according to a destination to be input.

Then, when receiving the ID code for identifying each station from the station signal generator through the station information receiving apparatus (S20), and receiving the station signal of the starting point at which the current user is to be set for the destination for the first time. Continue to drive the step (S20) until.

In addition, when the reception is completed (S30), the destination is input using a keypad or the like provided for inputting symbols, letters, numbers, etc. from the user (S40), and the starting point, which is a reference in the step S20, is input. Since the destination is input in step S40, the controller outputs the path from the current station to the destination to be displayed to the user (S50).

Then, information on waypoints, transfer destinations, etc. is output according to the shortest distance, minimum time, minimum transfer, and the like, and the user waits until the user selects a route (S61).

Here, when the user completes the route selection (S60), the user is driven to guide the user through the station and the transfer information, etc. while moving to the user using the information according to the selected route (S70), and the public transportation information guidance. Until the program ends, the process returns to step S20 to repeatedly drive the public transportation information guide program according to the present invention.

FIG. 6 is a flowchart illustrating a process of guiding public transportation information of FIG. 5 in detail. As shown in the figure, the public transit information guide process according to the present invention begins by outputting a text, voice, vibration, etc. containing a message according to the guide program to the user (S71).

Then, it waits until it detects the station signal of the next station signal generator (S73), and if the station signal of the next station signal generator is detected (S72), the station signal detected in the step S72 is Ask whether it is close to the destination (S74), and outputs an alarm message using text, voice, vibration, etc. so that the user does not pass the destination.

Here, the alarm message may be output differently according to the function of the output device of the mobile terminal, and may be output to include any one of text, voice, and vibration according to the user's setting, or according to the user's setting. Text, voice, vibration presence, intensity, etc. are set and can be changed.

When the stop information received in step S74 is not close to the destination, the stopover information including transfer information is guided (S76), and the step S72 is performed to determine whether the stop signal generator is detected. And then drive accordingly.

In addition, when the currently received stop information is the same as the destination, that is, when the destination has been completed by the user to enter the destination, the step of asking whether the user terminated the public transportation information guide program according to the present invention Move to S80.

If the currently received stop information is not the same as the destination, the process moves to step S74 in which the stop information is close to the destination input by the user to drive the program according to the present invention.

FIG. 7 is a detailed flowchart illustrating a stopover information guiding process including transfer information of FIG. 6. As shown in the figure, the waypoint information guiding process including transfer information according to the present invention starts with outputting waypoint information according to a route selected by the user (S76-1).

Here, it is asked whether or not the station information of the station information receiving device attached to the mobile terminal is detected (S76-2), and if the stop information is not detected after detecting stop information until the next stop is reached. Wait (S76-3).

Then, it is asked whether the stop signal detected in the step (S72-2) is close to the transfer area (S76-4), and outputs an alarm message using text, voice, vibration, etc. so that the user does not pass the transfer area (S76-). 5).

Here, the alarm message may be output differently according to the function of the output device of the mobile terminal, and may be output to include any one of text, voice, and vibration according to the user's setting, or according to the user's setting. Text, voice, vibration presence, intensity, etc. are set and can be changed.

When the station information received in the step S76-4 is not close to the transfer location, the method determines whether the station information of the station information receiver attached to the mobile terminal is detected (S76-2). To return.

In addition, if the currently received stop information is the same as the transfer destination, that is, when the transfer destination is reached, the step of informing the transfer information is terminated and the process returns to the step S72.

If the currently received stop information is not the same as the transfer place, the process moves to step S76-4 in which the stop information is close to the transfer place input by the user to drive the program according to the present invention.

In the above described exemplary embodiments of the present invention by way of example, the scope of the present invention is not limited to this specific embodiment, and those skilled in the art within the scope described in the claims of the present invention Changes may be made as appropriate.
