When the extracted unique ID information matches each other, the user terminal 204 provides a notification that the user has arrived at the notification station. When the user receives a notification from the user terminal 204 , the user gets off the station exactly without missing a station to get off, so that the convenience of using the train is improved. Each specific process included in the station arrival notification method will be described in detail with reference to FIGS. 3 and 4 .

3 is a flowchart illustrating a method for notifying a station arrival using an intelligent braille block according to an embodiment of the present disclosure.

Hereinafter, with reference to FIG. 3, each process of a method of providing a station arrival notification using a first RF signal (RFS ₁ ) received by a user terminal from a first intelligent braille block (SBB ₁ , 100_A) Explain.

The user terminal 204 receives and stores an alarm station to which the user wants to receive a notification from the user (S300). The notification station input by the user may be any one of an arrival station to which the user wants to get off, a station immediately preceding the arrival station, and one or more stopping stations between a boarding station and an arrival station. Accordingly, the user may be provided with a notification only when entering an arrival station as needed, and may be provided with a notification every time the user enters a plurality of stopping stations selected by the user. A process in which the user terminal 204 receives the notification station will be described in detail with reference to FIGS. 6A to 6D .

The user terminal 204 is a first RF signal including the unique ID information of the station where the intelligent braille block 100 is installed and the location information of the first intelligent braille block 100_A from the first intelligent braille block 100_A (RFS ₁ ) is received, and the first RF signal is processed to extract the first unique ID (UID ₁ ) information (S302). As described above, the number of the intelligent braille block 100 such as 'first' is according to the order in which the user terminal 204 receives the RF signal, and is not limited according to the specific location where the intelligent braille block 100 is installed. . The first RF signal according to an embodiment of the present disclosure may be a signal transmitted in the form of an advertising packet according to a Bluetooth Low Energy (BLE) communication method, but is not limited thereto. The RF signal processing may be, for example, a process of extracting a Universally Unique IDentifier (UUID) from an advertising packet according to the BLE communication method by demodulating the RF signal. On the other hand, a specific method for the user terminal 204 to demodulate the RF signal to extract the UUID is common in the art, and a detailed description thereof will be omitted.

The user terminal 204 extracts the unique ID information (UID _A ) of the notification station received and stored according to the process S300 from the previously installed ID database (S304). The ID database includes unique ID information of each stop where the passenger gets on or off, and may be a part of data stored in the station arrival notification application. Accordingly, the user terminal 204 may extract the unique ID information of the notification station without data communication using the communication company network. Meanwhile, in step S300, the user may input a plurality of notification stations, for example, a first notification station to an M-th notification station, and in step S304, the user terminal 204 provides unique ID information (UID _{A_1} ) to the first notification station. Unique ID information (UID _{A_M} ) of the Mth notification station may be extracted, respectively.

The user terminal 204 compares the first unique ID information (UID ₁ ) extracted according to the process S302 with the unique ID information (UID _A ) of the notification station extracted according to the process S304 to determine whether the user has arrived at the notification station It is determined (S306). When the user inputs a plurality of notification stations according to process S300, a comparison operation with the first unique ID information may be sequentially performed on the unique ID information UID _{A_1} to UID _{A_M} of each of the plurality of notification stations.

The user terminal 204 determines that the user has arrived at the notification station only when the first unique ID information (UID ₁ ) and the unique ID information (UID _A ) of the notification station match each other, and provides a station arrival notification (S308) ). In an embodiment of the present disclosure, the station arrival notification may be provided in a visual form together with the name of the notification station using the display of the user terminal 204 . In another embodiment of the present disclosure, the station arrival notification may be provided in an auditory form using a speaker of the user terminal 204 or may be provided in a haptic type using vibration of the user terminal 204 . there is. The display, speaker and vibration of the user terminal 204 described in the embodiment of the present disclosure are exemplary means for providing a notification, and the station arrival notification is smart glasses, a smart band, and a wireless headphone ( It may be provided using an electronic device such as a wireless headphone.

The station arrival notification method according to the embodiment of the present disclosure is an RF signal transmitted from the intelligent braille block 100 installed in the platform, for example, a signal transmitted in the form of an advertising packet according to the BLE communication method. use Accordingly, the station arrival notification method described in the embodiment of the present disclosure has the effect of being able to provide station arrival notification without data communication using a telecommunication company network, compared to the prior art.

4 is a flowchart for improving the accuracy of a station arrival notification method using an intelligent braille block according to an embodiment of the present disclosure.

In FIG. 3 , the user terminal 204 compares the first unique ID information (UID ₁ ) extracted from the first RF signal (RFS ₁ ) with the unique ID information (UID _A ) of the notification station extracted from the ID database, thereby alerting the user The process of determining whether a station has arrived or not has been described. Hereinafter, with reference to FIG. 4, the user terminal 204 determines whether the user has arrived at the notification station based on the 1st to Nth RF signals received from the 1st to Nth (N is a natural number greater than or equal to 2) intelligent Braille block. Describe the verification process.

The user terminal 204 processes the first and second RF signals received from the first and second intelligent braille blocks 100_A and 100_B to extract first and second unique ID information (S400 to S406). The user terminal 204 requires the unique ID information extracted by processing at least two RF signals to determine the unique ID information of the station where the train enters by determining whether the sequentially extracted unique ID information matches each other. do it with

The user terminal 204 determines whether the extracted first and second unique ID information match each other (S408). When the first and second unique ID information do not match each other, the user terminal 204 continuously extracts the unique ID information from the received RF signal until the sequentially extracted unique ID information matches each other, and the second ( N-1) and it is determined whether the N-th unique ID information matches (S406, S402, S404).

When the extracted (N-1) and N-th unique ID information match, the user terminal 204 determines that the N-th unique ID information (UID _N ) is the unique ID of the station where the current train enters, It is determined whether the UID _N and the unique ID information (UID _A ) of the notification station match each other (S408, S410).

When UID _N and UID _A match each other, the user terminal 204 determines that the user has arrived at the notification station and provides the notification station arrival notification to the user (S412). In this way, when two consecutive unique ID information among the unique ID information extracted from the RF signal coincide with each other, by determining that the matching unique ID information is the unique ID information of the current station, the station arrival notification method accuracy can be improved. In another embodiment of the present disclosure, when N (N is a natural number greater than or equal to 2) consecutive unique ID information among each unique ID information extracted from the RF signal coincide with each other, the matching unique ID information is the current station It can be determined that the unique ID information of That is, the process of determining the unique ID information of the current station by comparing each unique ID information extracted from the RF signal may be changed as necessary, and is not limited to the process illustrated in FIG. 4 . When the user terminal 204 provides the notification station arrival notification according to step S412, the arrival notification of the same notification station is not provided in order to prevent user confusion.

When UID _N and UID _A do not match each other, the user terminal 204 determines that the user has not arrived at the notification station and stops RF signal processing for a preset time (S414). As described above, when it is determined that the current stop is not the notification station, the user terminal 204 stops the RF signal processing, thereby reducing the amount of computation of the user terminal 204 . At this time, the preset time is the difference between the time for receiving the RF signal from the intelligent braille block 100 installed at the current stop and the time for receiving the RF signal from the intelligent braille block 100 installed at the next stop, for example, 60 seconds (s) ) to 80 seconds.
