The communication terminal 10 is an acoustic information processing device that is configured by installing an application on, for example, a smartphone (smartphone) or the like, and enables sound reception (sound collection) from the speaker SK by acoustic communication. A more specific configuration example of the communication terminal 10 will be described later with reference to FIG.

Of the parking position information transmission system 500, the parking position information output device 60 is connected to a plurality of speaker SKs arranged in various places in the parking lot PA and the parking management unit 100 as shown in FIG. It is provided with an acoustic communication control unit SC connected to.

Each speaker SK transmits (outputs) an ultrasonic UL for providing information to the vehicle VE, but as shown in the figure, for example, even if the voice guidance VG is performed in the audible range in parallel with this. good. From a different point of view, each speaker SK may be used as a speaker for an announcement in the parking lot PA. Here, each speaker SK provides information on the parking position in individual contents according to the installation position of the parking lot PA. For example, it is conceivable to show the position information in the vehicle interior area unit composed of a plurality of vehicle compartments, or to show the position information in the vehicle interior unit in more detail. In the illustrated example, the speaker SKα arranged in the area α on the center side of the parking lot PA transmits a transmission wave ULα as information for transmitting that the parking position is in the center as an ultrasonic UL. Similarly, from the speaker SKβ located in the area β on the left side of the parking lot PA (on the right side when viewed from the entrance / exit DW), the transmitted wave ULγ as information for transmitting that the parking position is to the left is used as the ultrasonic UL. From the speaker SKγ, which is transmitted and is placed in the area γ on the right side of the parking lot PA (on the left side when viewed from the entrance / exit DW), the transmitted wave ULγ as information for transmitting that the parking position is to the right is used as ultrasonic UL. It will be sent.

The acoustic communication control unit SC is composed of a circuit board or the like, and controls the operation of the voice output of each speaker SK according to a command from the parking management unit 100. That is, as described above, the position information having different contents is output according to the installation position of each speaker SK.

In the example shown in FIG. 2, the parking management unit 100 includes a control device CT and a storage unit ME. The control device CT is composed of, for example, a CPU or the like, and performs various arithmetic processes. The storage unit ME is a memory or the like for storing various data and programs. Further, the storage unit ME functions as a parking management database in parking management.

Hereinafter, one configuration example of the communication terminal 10 from the functional aspect will be described in more detail with reference to FIG. 2.

As shown in the figure, the communication terminal 10 functions as an acoustic information processing device capable of acquiring information by acoustic communication by including a microphone MCm, a display unit DSm, a main control unit 11, and a storage unit 12. .. As described above, the communication terminal 10 is an in-vehicle portable terminal configured by installing an application on, for example, a smartphone. In this case, for the microphone MCm or the like, an existing device is used on the smartphone, for example. It is possible to do.

The microphone MCm can receive the ultrasonic UL transmitted as a transmitted wave from the speaker SK installed in the parking lot PA. Further, the communication terminal 10 has a display unit DSm composed of, for example, an organic EL panel, and can visualize and display parking position information based on the reception result from each speaker SK (see FIG. 5). ).

The main control unit 11 is composed of a CPU or the like, is connected to a microphone MCm, a display unit DSm, and a storage unit 12, performs various arithmetic processes, outputs various command signals to each unit, and performs various operations as described above. Controls about.

The storage unit 12 stores various programs, data, and the like necessary for receiving a signal from the above-mentioned application, that is, the speaker SK, and grasping the parking position based on the reception result (see FIG. 5). The main control unit 11 appropriately reads out various programs, data, and the like stored in the storage unit 12 and performs various operation controls.

As described above, the communication terminal 10 extracts acoustic communication data from the microphone MCm that receives the sound wave output from the speaker SK, which is the acoustic communication speaker, and the sound wave received by the microphone MCm as the acoustic information processing device. It has a main control unit 11 as a data processing unit for acquiring information on the parking position, and a display unit DSm which is an output unit for outputting the recognized parking position.

It is assumed that the communication terminal 10 composed of a smartphone or the like is in a state in which an application necessary for enabling the above communication is activated in advance when the vehicle VE is parked in the passenger compartment. Various aspects can be considered for this, for example, the application may be always started not only when parked, and the user, that is, the owner of the communication terminal 10 may manually start the application. Further, for example, a voice guidance VG (see FIG. 1) may be performed from the speaker SK to urge the user to start the application by another method. Alternatively, the application may be activated or prompted to be activated at the entrance / exit DW when entering the parking lot PA.

Hereinafter, the arrangement and operation of each speaker SK constituting the parking position information output device 60 will be described with reference to FIGS. 3 and 4.

First, referring to the conceptual plan view of FIG. 3, a speaker SK, which is an acoustic communication speaker, is installed in a vehicle interior area unit composed of a plurality of vehicle interior RMs, and information on the vehicle interior area is acoustically input. An example will be described with respect to the mode of outputting by communication. In FIG. 3, an area α composed of three side-by-side vehicle interior RMs and an area β composed of five side-by-side vehicle interior RMs are exemplified. In the illustrated example, the speaker SKα of the speaker SK is installed in the area α, and the transmitted wave ULα is transmitted from the speaker SKα as an ultrasonic UL according to a command from the parking management unit 100 via the acoustic communication control unit SC. Is output. The transmitted wave UL α contains information for making it possible to identify that the parking position is the area α in the communication terminal 10. That is, the communication terminal 10 can recognize that the current parking position is the area α by receiving (receiving) the transmitted wave ULα in the area α.

Similarly, a speaker SKβ is installed in the area β, and a transmission wave ULβ containing information for making it possible to identify the parking position in the communication terminal 10 as an ultrasonic UL from the speaker SKβ is provided. It is being output.

That is, the transmitted wave ULα from the speaker SKα and the transmitted wave ULβ from the speaker SKβ include information having different contents from each other in order to specify the individual parking positions. In addition to the individual information regarding the parking position, the transmitted waves ULα and ULβ may include various information such as a parking lot name (○○ parking lot) and a parking time.

In the illustrated example, one speaker SKα corresponds to the area α including the three vehicle interior RMs for the plurality of set speaker SKs. On the other hand, two speakers SKα correspond to the area β including the five wider vehicle interior RMs. However, the number and arrangement status of the speaker SKs to be arranged are merely examples, and the present invention is not limited to this, and various modes can be used.

Hereinafter, with reference to the conceptual plan views of FIGS. 4 (A) and 4 (B), a speaker SK, which is an acoustic communication speaker, is provided for each vehicle interior RM, and is provided in a predetermined area of the corresponding vehicle interior. An example of the mode of emitting a sound wave will be described. In FIG. 4A, among the speaker SKs, a plurality of speakers Sα1, Sα2, correspond to a plurality of vehicle compartments Rα1, Rα2, Rα3, etc., which are vehicle compartment RMs arranged side by side in the area α, for example. Sα3 ... is installed. Similarly, a plurality of speakers Sβ1, Sβ2, Sβ3 ... Are installed corresponding to each of the plurality of vehicle interiors Rβ1, Rβ2, Rβ3 ... Constituting the area β. From each speaker Sα1, Sα2, Sα3, Sβ1, Sβ2, Sβ3 ..., Information having different contents is included in order to specify individual parking positions. That is, the transmission waves Uα1, Uα2, Uα3, Uβ1, Uβ2, Uβ3, ...

In the case of the illustrated example, the parking position is the vehicle compartment Rα2 by receiving (receiving) the transmitted wave Uα2 from the speaker Sα2 in the communication terminal 10 mounted on the vehicle VE parked in the vehicle compartment Rα2. That is, it can be recognized that it is the second position of the area α.

Here, in order to achieve the above aspect, it is desired that the transmitted wave Uα1 or the like transmitted toward each vehicle compartment RM does not interfere with the transmitted wave Uα2 or the like of the adjacent vehicle compartment RM. Therefore, for example, as shown in FIG. 4B, the receivable range of the ultrasonic UL in each vehicle compartment RM is limited to the range DA inside each vehicle compartment RM, and the range is limited to the other ranges adjacent to each other. An interference range BU is provided between the two. In order to bring about such a state, the ultrasonic UL transmitted from each speaker SK has directivity and the output intensity is appropriately adjusted. It should be noted that the directivity and the output intensity can also be adjusted in the acoustic communication in the area unit illustrated in FIG. 4 (A).

Hereinafter, an example of operation processing in the portable communication terminal 10 as an acoustic information processing device will be described with reference to FIG. FIG. 5A is a block diagram showing a configuration example of the storage unit 12 of the communication terminal 10 as an acoustic information processing device. Further, FIG. 5B is a conceptual front view showing an example of a display mode on the communication terminal 10.

First, in the example of FIG. 5A, the storage unit 12 has a program storage unit 12p and a data storage unit 12d. Of these, the program storage unit 12p stores the speaker voice recording program RC and the parking position collation program VF. On the other hand, the data storage unit 12d includes a recording data unit RD, a parking lot data unit PD, and a parking status data unit SD.

In the program storage unit 12p, the speaker voice recording program RC analyzes the ultrasonic UL from the speaker SK received by the microphone MCm and can extract various information such as parking position information (acoustic communication data). It is a program for recording as. The parking position collation program VF is a program for collating the data analyzed by the speaker voice recording program RC with the data related to the parking lot and specifying the parking position corresponding to the received sound data.

In the data storage unit 12d, the recording data unit RD, for example, raw audio data of the ultrasonic UL received by the microphone MCm, data analyzed by the speaker audio recording program RC (acoustic communication data), and the like during parking. Stores various data related to recording. The parking lot data unit PD stores data for collating the parking position in the parking position collation program VF. That is, the parking lot data unit PD stores map information and the like about the vehicle interior position in the target parking lot. The parking status data unit SD stores various data related to the parking status of the vehicle VE, such as the result of collation by the parking position collation program VF and the time at the time of parking.

These programs and data stored in the storage unit 12 are appropriately read out by the main control unit 11 and various processes are performed. As a result, the user of the communication terminal 10 can perform an appropriate operation to display, for example, an image GG as illustrated in FIG. 5B on the display unit DSm. That is, after parking, the user can confirm the parking position of his / her vehicle by operating the communication terminal 10 as necessary.

As described above, the parking position information transmission system 500 according to the present embodiment has a speaker SK, which is an acoustic communication speaker that outputs parking position information corresponding to an installed portion of the parking lot PA by acoustic communication. It includes a parking position information output device 60 and a communication terminal 10 which is an acoustic information processing device which can be mounted on a vehicle and receives information from a speaker SK to recognize a parking position. As a result, in the parking position information transmission system 500, the vehicle-mounted communication terminal 10 receives the information by acoustic communication from the speaker SK of the parking position information output device 60 and recognizes the parking position to transmit the parking position information. This makes it possible to easily and reliably detect the parking position on the vehicle VE side.

Further, in the above embodiment, by using the acoustic communication by ultrasonic waves, the directivity can be given as compared with the case of using the radio wave communication using, for example, UHF, so that the vehicle other than the target vehicle to be communicated with can be provided. It becomes easier to avoid interference with the vehicle. In the above, ultrasonic waves are used, but the present invention is not limited to this, and sound waves in the audible range may be used. For example, the information for parking management may be mixed in the voice guidance VG within a range that does not interfere with the normal voice guidance VG.

Further, the speaker SK, which is an acoustic communication speaker according to the present embodiment, is installed at a predetermined location in the parking lot PA, and outputs information on the parking position corresponding to the installed location by acoustic communication. In the speaker SK, information on the parking position corresponding to the installation location of the device can be easily and accurately transmitted to the device capable of receiving the acoustic communication.

Further, the portable communication terminal 10 according to the present embodiment receives a sound wave including parking position information, extracts acoustic communication data from the received sound wave, and recognizes the parking position. In the communication terminal 10, the parking position can be detected easily and reliably by receiving the parking position information from the device (parking position information output device 60) capable of outputting by acoustic communication.

Further, in this case, as for the parking position information to be transmitted as the ultrasonic UL, the information stored in the control board CTs can be used as necessary for parking management.

FIG. 6B shows an example of a configuration of a so-called lock-type parking lot. By attaching a pole POa having a speaker SK that emits ultrasonic UL to a flap device (flap plate) FP, the pole POa Can function as a parking position information output device. For example, by connecting the control board CTs of the pole POa to the control board CTf of the flap device FP, information on the parking position to be transmitted as ultrasonic UL can be acquired from the control board CTf. Further, the pole POa may be able to receive electric power from the power supply PS of the flap device FP via, for example, the control board CTf.

Further, FIG. 14 illustrates a case where one parking management unit 100 manages a plurality of entry / exit management units 50.

First, each part of the entry / exit management unit 50 will be described. As shown in FIGS. 13 and 14, and as described above, the entry / exit management unit 50 includes an acoustic communication unit 20, a vehicle detection unit 30, and a gate unit 40.

In addition, the entry / exit management unit 50 includes, for example, as shown in FIG. 14, a main control unit 51 composed of a CPU and the like, and a storage unit 52 composed of various storage devices. Further, in the illustrated example, among those constituting the main control unit 51, the storage unit 52, the acoustic communication unit 20, the vehicle detection unit 30, and the gate unit 40, the part related to the operation control is referred to as the control base unit MP. For example, it is integrally formed by a housing (see FIG. 12).

Hereinafter, among the respective parts of the entry / exit management unit 50, the acoustic communication unit 20 will be described in more detail.

The acoustic communication unit 20 has a speaker SKK that emits ultrasonic ULL for communication, a microphone MCC that receives ultrasonic ULL transmitted from the vehicle side, and an acoustic communication control that controls the acoustic communication operation of the speaker SKK and the microphone MCC. A unit 21 is provided.

Among the acoustic communication units 20, first, as illustrated in FIG. 13, the speaker SKK is the first speaker SKKa installed toward the entering vehicle VE and the first speaker SKK installed toward the participating vehicle VE. It is composed of two speakers SKKb. For example, as shown in the figure, the first speaker SKKa transmits a transmission wave TW, which is an ultrasonic ULL, to the communication terminal 10 mounted on the vehicle VE to enter, and the communication terminal 10 transmits the transmission wave TW to the communication terminal 10. The response wave RW is transmitted.

Next, the microphone MCC is a sound collecting device that receives an ultrasonic ULL for communication (for example, the response wave RW described above) transmitted from the communication terminal 10. That is, the microphone MCC has sensitivity and directivity capable of receiving the ultrasonic UL from the communication terminal 10 mounted on the vehicle VE when the vehicle VE is in the position where the vehicle should enter or the position where the vehicle VE should enter. There is.

Finally, the acoustic communication control unit 21 is composed of, for example, a circuit board or the like, and is connected to the main control unit 51 in the control board unit MP as shown in FIG. 14, according to the instruction from the main control unit 51.

The loop coil LC is composed of a first loop coil LCa embedded immediately outside the doorway DW and a second loop coil LCb embedded immediately inside the doorway DW. The loop coil detection unit 31 is composed of, for example, a circuit board or the like, is connected to the loop coils LCa and LCb, and is connected to the main control unit 51. The loop coil LCa and LCb are connected to the main control unit 51. The result of vehicle detection is output. In the illustrated example, the presence or absence of vehicle VE in the detection ranges DAa and DAb is detected by each loop coil LCa and LCb, and based on this detection result, the access control unit 50 starts communication by the acoustic communication unit 20. Will be done.

Here, the first speaker SKKa efficiently transmits the ultrasonic UL as the transmission wave TW to the detection range DAa, and the ultrasonic UL is super-transmitted to a range other than the detection range DAa as much as possible. Transmission is performed with the sound wave UL having directivity. In particular, when there is a following vehicle to be parked in the parking lot PA, it is conceivable to adjust the directivity of the transmitted wave TW in order to suppress the mixture of communication with the following vehicle. As described above, accurate communication is performed between the acoustic communication unit 20 which is the parking lot side acoustic communication unit and the communication terminal 10 which is the vehicle side acoustic communication unit by the directional ultrasonic UL. You can communicate about various ranges and directions.

Next, the gate unit 40 is a gate device including a main body portion GE composed of a gate bar BA or the like and a gate control unit 41. The main body portion GE indicates whether or not the vehicle VE can proceed into the parking lot PA by raising and lowering the gate bar BA at the entrance / exit DW of the parking lot PA. The gate control unit 41 is connected to the main control unit 51, and the main control unit 51 determines (instructs) whether or not to allow passage of the vehicle VE according to the communication result between the communication terminal 10 and the acoustic communication unit 20. Therefore, the ascending / descending operation of the gate bar BA is controlled.

In contrast to the above, in the vehicle VE equipped with the communication terminal 10, when entering the parking lot PA, first, the vehicle passes through the gate by acoustic communication between the entry / output management unit 50 and the communication terminal 10, and then the parking position. When the vehicle VE is stored in the warehousing, the parking position is stored by acoustic communication between the parking position information output device 60 and the communication terminal 10. In addition, in the above-mentioned series of operations related to parking, for example, by starting the application that is in a standing state at the time of admission as it is, it is possible to perform necessary processing in the operation from admission to parking. It should be noted that the processing may be performed individually at the time of admission and at the time of warehousing.

Hereinafter, an example of parking management in the parking management unit 100 in the above-described embodiment will be described.

The parking management unit 100 relates to information on the vehicle VE acquired by acoustic communication in the entry / exit management unit 50 and the parking position of the vehicle VE acquired by acoustic communication in the parking position information output device 60 when entering and exiting the vehicle VE. By acquiring the information, for example, a data table as shown in FIG. 15A can be created and parking can be managed. That is, the entry / exit management unit 50 outputs the ID information and the like of the communication terminal 10 at the time of admission, and then the parking position information output device 60 outputs the parking position information and the like associated with the ID information and the like of the communication terminal 10. To. In addition, the entry / exit management unit 50 outputs information on participation. From these, a data table as shown in FIG. 15A is created. For the entry time, it is conceivable to use the communication time of the entry / exit management unit 50 or the parking position information output device 60, and for the entry time, the communication time of the entry / exit management unit 50 or advance settlement can be used. In the case of, it is conceivable to use the time at that time. In addition, various modes can be considered for the settlement process. Further, also in the above case, for example, a data table as illustrated in FIG. 15B is stored as information registered in advance in the storage unit ME of the parking management unit 100. Here, as the stored cormorant information, in addition to the information illustrated in FIG. 9A, various information may be included as needed, for example, communication between the parking lot side and the communication terminal 10. The communication method for performing the above may be defined. Here, as described above, acoustic communication is performed by ultrasonic UL, but the sound range (frequency band), communication range, directivity, etc. applied at that time may be appropriately determined.

As described above, in the parking position information transmission system 700 according to the present embodiment, as in the other embodiments, the parking position information output device 60 enables the information transmission of the parking position to the communication terminal 10 and further. By using the entry / output management unit 50 and the parking position information output device 60 in the parking management unit 100, centralized management regarding parking is possible.

Further, in the above, the mode of using a smartphone is shown as an example of the communication terminal 10 that can be mounted on a vehicle, but if the device has equipment for enabling acoustic communication such as a microphone and a speaker, a device other than the smartphone is used. May be adopted as the communication terminal 10. In the present embodiment, as described above, the communication terminal 10 can be easily and surely configured by enabling acoustic communication by using the microphone and the speaker which are the existing equipments in the smartphone. For example, warehousing / delivery management using NFC (Near Field Communication) can be considered, but in this case, it cannot be used with a smartphone not equipped with the NFC function.

For example, when using the NFC function or QR code (registered trademark) of a smartphone, the user needs to perform operations such as holding the smartphone over a device installed in a parking position or a QR code (registered trademark). In the case of acoustic communication, for example, by automatically starting up the smartphone or always starting it up, it is possible to make it a mode that does not require such trouble.

Further, various modes of transmission for acoustic communication can be considered, and for example, the directivity, that is, the direction of transmission, the frequency band to be used, the transmission intensity, and the like may be variously changed. For example, the optimum frequency band, transmission intensity, and the like may be selected according to the characteristics of the pre-registered communication terminal 10 (for example, the type of smartphone). Alternatively, it is conceivable to change the directivity in consideration of the size of the vehicle VE and the like.

Further, for example, various modes can be considered for an application for making a smartphone usable as a communication terminal 10. For example, when a parking lot PA is attached to a commercial complex, the commercial complex has the same aspect as the application. It may be attached to the application to be used, and it may be possible to apply a discount on the parking lot fee, for example, by associating it with various information registered when using the application.

Further, various aspects of the parking management unit 100 can be considered, and for example, the parking management unit 100 may be configured by a cloud-type server. Further, the acoustic communication control unit SC and the like of the parking position information output device 60 may be shared with the parking management unit 100.
