In the following description, “sound wave output device 102” is used to indicate an arbitrary sound wave output device among the plurality of sound wave output devices 102-1 to 102-3. Similarly, when an arbitrary section is indicated among the plurality of sections 103-1 to 103-3, “section 103” is used.

  Note that the numbers of the sound wave output devices 102 and the partitions 103 in FIG. 1 are examples, and other numbers may be used. In the present embodiment, for example, a large effect can be expected in a place where there are a large number of sections 103 (for example, parking sections) such as a large parking lot, but in FIG. The number is 3.

  The sound wave output device 102-1 is provided corresponding to the section 103-1, and outputs a sound wave including unique information corresponding to the section 103-1. Similarly, the sound wave output device 102-2 is provided corresponding to the section 103-2, and outputs a sound wave including unique information corresponding to the section 103-2. Furthermore, the sound wave output device 102-3 is provided corresponding to the section 103-3, and outputs a sound wave including unique information corresponding to the section 103-3. The sound wave output device 102 includes, for example, an electroacoustic conversion element such as a speaker.

  For example, the sound wave output device 102 stores in advance a speaker ID that is identification information of the own device, and outputs this speaker ID as a unique information described above in a sound wave. Alternatively, the sound wave output device 102 has a function of communicating with the server device 106 via a network 107 such as the Internet or a LAN (Local Area Network), for example, and uses information specified by the server device 106 as specific information. It may be a thing. In the example of FIG. 1, the sound wave output device 102-1 has its own speaker ID “SP000001”, the sound wave output device 102-2 has its own speaker ID “SP000002”, and the sound wave output device 102-3 has its own device ID. Sound waves including the speaker ID “SP000003” are output.

In addition, it is desirable that the partition number is displayed on the partition 103 and its surroundings so that the user 105 can easily recognize it. In the present embodiment, the section 103 assumes a parking space for one vehicle. However, the section 103 may include a plurality of parking spaces, and the parking lot is divided into a plurality of areas. The thing etc. which were done may be sufficient.

  The terminal device 104 is an information processing device such as a smartphone, a mobile phone, or a tablet terminal that the user 105 has, and can transmit and receive data to and from the server device 106 by connecting to the network 107 by wireless communication or the like. . Further, the terminal device 104 can acquire the sound wave output from the sound wave output device 102 using a built-in microphone or the like, and can specify the unique information of the sound wave output device 102 included in the acquired sound wave.

Hereinafter referred to as a registration information DB). The registration information DB is stored in advance in storage means such as the terminal device 104 and / or the server device 106, for example. The terminal device 104 determines the partition 103 where the terminal device 104 is currently located based on the specific information identified from the sound wave output from the sound wave output device 102 and the registration information DB, and information on the partition 103 where the terminal device 104 is located. Can be displayed.

Further, the server device 106 may have a function of setting unique information transmitted by the sound wave output device 102 by transmitting unique information such as a speaker ID to the sound wave output device 102 via the network 107. .

  With the above configuration, when the user 105 located in the section 103-1 in FIG. 1 starts an application corresponding to the location management system 100 installed in the terminal device 104, the terminal device 104 outputs from the sound wave output device 102-1. The acquired sound wave is acquired with a microphone. Further, the terminal device 104 identifies the speaker ID “SP000001” included in the acquired sound wave, and determines that it is currently located in the section 103-1 based on the registration information DB stored in advance in the storage unit. Can do.

  Similarly, when the terminal device 104 moves to the partition 103-2, the terminal device 104 acquires the sound wave output from the sound wave output device 102-2, and currently, based on the speaker ID “SP000002” included in the acquired sound wave, the partition 103 -2 can be determined.

  Thereby, the user 105 who is a user of the parking lot easily uses the application or the like corresponding to the position management system 100 to park the parked section 103 on the terminal device 104 or the server device 106 when the vehicle is parked. You can register. Further, when searching for a parked vehicle, the user 105 can display the section 103 where the vehicle is parked and the section 103 where the user 105 is located on a parking lot map or the like.

  When receiving the registration response from the server device 106, the terminal device 104 displays the parking position number included in the registration response, for example, as shown in FIG. 10B (step S1608).

(Parking position confirmation process)
FIG. 17 is a sequence chart of the parking position confirmation process according to the second embodiment. For example, when the user 105 who is a user of the parking lot returns to the parking lot after finishing shopping or the like, the user 105 activates an application corresponding to the location management system 100 installed in the terminal device 104 (step S1701).

  The terminal device 104 activates an application in response to the activation operation of the user 105 (step S1702), and displays an operation screen (step S1703).

  The user 105 performs a parking position confirmation operation (for example, selecting “return to parking” from the menu) from the operation screen of the terminal device 104 (step S1704).

  The terminal device 104 makes a parking position confirmation request to the server device 106 in response to the user 105's parking position confirmation operation (step S1705). The parking position confirmation request includes, for example, a mobile terminal ID, mode information indicating a parking position confirmation request, and the like.

  In response to the parking position confirmation request from the terminal device 104, the server device 106 acquires the speaker ID corresponding to the requested terminal ID from the registration information DB (step S1706), and acquires the acquired speaker ID or A confirmation response including the parking position number and the like corresponding to the speaker ID is transmitted to the terminal device 104 (step S1707).

  The terminal device 104 creates a parking position display screen as shown in FIG. 12, for example, based on the speaker ID or the parking position number included in the confirmation response received from the server device 106 (step S1708). The displayed display screen is displayed (step S1709).

(Route guidance processing)
FIG. 18 is a sequence chart of route guidance processing according to the second embodiment. When the user 105 performs a route guidance operation for the parking position (step S1801), the terminal device 104 acquires a sound wave (step S1802) and specifies a speaker ID included in the acquired sound wave (step S1803). In addition, the terminal device 104 transmits a route request for the parking position including the mobile terminal ID, the speaker ID, and mode information indicating the route request to the server device 106 (step S1804).

  Upon receiving the parking position route request from the terminal device 104, the server device 106 acquires a parking position number corresponding to the speaker ID included in the route request and a parking position number corresponding to the mobile terminal ID (step S1805). Further, the server device 106 transmits a route response including the parking position number corresponding to the acquired speaker ID and the parking position number corresponding to the mobile terminal ID to the terminal device 104 (step S1806).

  Based on the parking position number corresponding to the speaker ID received from the server apparatus 106 and the parking position number corresponding to the mobile terminal ID, the terminal device 104 creates a route guidance screen as shown in FIG. Step S1807). The terminal device 104 displays the created route guidance screen (step S1808).

(Exit processing)
As described above, when the user 105 performs the parking position confirmation process or the route guidance process, the terminal device 104 may acquire sound waves continuously at predetermined intervals by the sound wave acquisition unit 501. Thereby, the terminal device 104 can determine that the user 105 has arrived at the section 103 where the vehicle is parked when the unique information included in the acquired sound wave matches the unique information of the parking position. At this time, the terminal device 104 can transmit the store closing information to the server device 106, and the server device 106 can record the store closing date 1506 in the registration information DB 1500.

(Processing at closing)
The manager of the parking lot, for example, accesses the registration information DB 1500 when the store is closed, and confirms the presence / absence of the parking position number 1503 and the portable terminal ID 1504 in which the store closing date 1506 is not recorded. Thereby, for example, the manager checks whether or not the parking position number 1503 in which the store closing date and time 1506 is not recorded is parked. If the vehicle is parked, the manager uses the portable terminal ID 1504 to close the store. It is possible to promptly exit from the store.

(Other processing)
For example, when an administrator of the parking lot finds an abnormality in the vehicle such as forgetting to turn off the light, the parking location number 1503 can be used to obtain the mobile terminal ID 1504 from the registration information DB 1500. Thereby, the manager of the parking lot can notify the user 105 of the terminal device 104 of the abnormality through a call addressed to the terminal device or SMS (Short Message Service). Alternatively, an application corresponding to the position management system 100 may display a notification or the like of the vehicle abnormality to the user 105 on the display screen of the terminal device 104 or the like. In this case, the user who has dealt with the vehicle abnormality can press the abnormality release button or the like of the terminal device 104 to notify the administrator or the position management system 100 that the abnormality has been resolved.

<Directional characteristics of sound waves of the sound wave output device>
It is desirable that the sound wave output device 102 that outputs a sound wave including unique information (speaker ID or the like) corresponding to the section 103 has a directivity characteristic corresponding to the section 103.

  FIG. 19 is a diagram for explaining a speaker according to an embodiment. Since the directivity of a general speaker is uniform, for example, as shown in FIG. 19A, when the reach of a sound wave by the speaker 1900 is matched with the width direction of the vehicle 1901, the sound wave in the length direction of the vehicle is Insufficient reach. In this case, before and after the vehicle 1901, a situation in which the terminal device 104 cannot acquire sound waves may occur.

  On the other hand, for example, as shown in FIG. 19B, when the reach of the sound wave by the speaker 1900 is matched with the length direction of the vehicle 1901, the sound wave output device 102 corresponding to another section 103 adjacent in the width direction of the vehicle 1901. There is a risk of interference with sound waves from. The speaker 1900 is an example of the sound wave output device 102.

  FIG. 20 is a diagram for explaining the directivity characteristics of the speaker according to the embodiment. FIG. 20A shows a side view of the speaker 2000, which outputs sound waves in the right direction of the figure. FIG. 20B is a front view of the speaker 2000, and it is assumed that sound waves are output in the front direction of the figure. 20B, the X direction (first direction) is the longitudinal direction of the vehicle 1901 or the section 103, and the Z direction (second direction) intersecting the X direction is the width direction of the vehicle 1901 or the section 103. And The speaker 2000 is an example of the sound wave output device 102.

  Here, when a sound wave including unique information corresponding to the section 103 is transmitted from the speaker 2000, it is desirable that the sound pressure level in the X direction of the speaker 2000 and the sound pressure level in the Z direction of the speaker 2000 are different. Preferably, when a sound wave including unique information corresponding to the section 103 is transmitted from the speaker 2000, the sound pressure level in the Z direction of the sound wave is preferably lower than the sound pressure level in the X direction of the sound wave.

  As a specific example, the standard parking regulations that the Ministry of Land, Infrastructure, Transport and Tourism has informed for reference when reflecting in the parking regulations established by local governments include the size of the standard parking area, width 2 .3m or more and depth of 5m or more are described. According to this, in order to reduce the leakage of sound waves to the parking spaces adjacent in the horizontal direction and to cover the vertical direction of the parking spaces with sound waves, the sound pressure level in the X direction of the speaker 2000 and the Z direction The ratio of the sound pressure levels is preferably 5 / 2.3 = 2.17 or more, for example.

  Also, if this ratio is large, sound wave leakage occurs in the front-rear direction of the parking section. Preferably, the ratio of the sound pressure level in the X direction of the speaker 2000 to the sound pressure level in the Z direction is about 2.2. (For example, 2.17 or more and 2.23 or less) is desirable.

[Other Embodiments]
In the position management system 100, the sound wave output device 102 transmits unique information (for example, a speaker ID) by sound waves having a frequency of 16 kHz or higher that is difficult for humans to hear. However, this sound wave can be recorded by a recording device such as a voice recorder. Therefore, for example, in order for a malicious person or the like to interfere with the position management system 100, a sound wave including specific information is recorded by a voice recorder or the like, and the recorded sound wave is reproduced by another speaker. The specific information may be changed. A similar problem can occur when a non-malicious person records a sound wave including unique information and reproduces it at another location without his / her awareness.

  In order to reduce such a problem, it is desirable that the position management system 100 encrypts the unique information transmitted by the sound wave output device 102 and changes the encryption key used for encryption with time, for example.

  For example, the server device 106 updates an encryption key for encrypting the unique information at a predetermined time interval and a decryption key for decrypting the encrypted unique information. In addition, the server device 106 transmits the updated encryption key to the sound wave output device 102 via the network 107 or the like. The sound wave output device 102 encrypts the unique information using the encryption key received from the server device 106, and outputs a sound wave including the encrypted unique information. Thereby, the unique information included in the sound wave output from the sound wave output device 102 is encrypted, and the encryption key used for encryption is changed (updated) with time.

  In addition, the terminal device 104 that has received the sound wave including the encrypted unique information requests the server device 106 to obtain a decryption key for decrypting the unique information. The server device 106 transmits the updated decryption key to the terminal device 104 in response to a request from the terminal device 104. The terminal device 104 can decrypt the encrypted unique information using the decryption key received from the server device 106.

  According to the present embodiment, it is possible to reduce malfunctions that may occur when the unique information output by the sound wave output device 102 is recorded and reproduced at another location.
