1 is a schematic diagram of a mobile monitoring system according to a first embodiment; FIG. 1 is a block diagram of a computer; FIG. It is a figure which shows typically the collation operation|movement of the identification information in a control part. It is a schematic diagram of the mobile monitoring system by 2nd Embodiment.

[Premise of the embodiment]
The mobile monitoring system according to the embodiment described later distinguishes mobiles equipped with registered child devices (hereinafter referred to as "registered mobiles") and mobiles equipped with unregistered child devices or mobiles without child devices (hereinafter both referred to as "unregistered mobiles"). The mobile object monitoring system monitors these mobile objects by managing the locations of these mobile objects. As a result, the mobile object monitoring system distinguishes registered mobile objects that are permitted to operate the door from unregistered mobile objects that are not permitted (for example, an intruder), and prevents them from tailgating into or exiting a managed building.

With the technique of Patent Literature 1 described above, entrance/exit management that prevents tailgating is certainly possible. However, since entry into and exit from the entrance/exit management area is performed through the "anteroom", the equipment becomes large-scale. On the other hand, each embodiment to be described later achieves tailgating prevention with a small-scale equipment configuration. Further, in the technique disclosed in Patent Document 1, identity verification is performed by biometric authentication (fingerprint verification). This identity verification takes a long time because it stops the person entering and leaving the room. Furthermore, there may be cases where it is difficult to obtain a fingerprint, such as when the finger is injured. Each embodiment to be described later solves these problems as well as preventing tailgating.

[First embodiment]
<Structure of the first embodiment>
FIG. 1 is a schematic diagram of a mobile monitoring system 1 according to the first embodiment.
The mobile monitoring system 1 includes a base unit 10 , a base unit antenna 12 , a sensor unit 14 , a control unit 60 , a door 82 and a locking/unlocking device 84 . A plurality of moving bodies 30-1, 30-2, and 30-3 are positioned around the door 82. As shown in FIG. In the following description, a plurality of components, information, etc. having the same or similar functions and meanings may be denoted by the same reference numerals with "-" added, such as "moving bodies 30-1, 30-2, 30-3". However, when there is no need to distinguish between these plural components, they may be indicated by omitting "-" and numerals, such as "moving body 30". The moving body 30 is, for example, a person (human) who enters and exits the hall, but may be a trolley, a carrier, or the like.

In the illustrated example, mobile units 30-1 and 30-2 are provided with child devices 20-1 and 20-2, respectively, but mobile device 30-3 is not provided with child device 20. FIG. Each child device 20 has a child device antenna 22 . However, the child device antenna 22 may be built in the child device 20 . The slave device 20 may be a dedicated terminal applied to the mobile monitoring system 1, or may be a general-purpose terminal such as a smart phone. Also, the parent device 10 is connected to the parent device antenna 12 and communicates with the child device 20 via the parent device antenna 12 . However, the parent device antenna 12 may be built in the parent device 10 .

Base unit 10 and slave unit 20 perform first wireless communication using first protocol P1 (not shown) and second wireless communication using second protocol P2 (not shown). The parent device antenna 12 and the child device antenna 22 described above are compatible with both the first and second protocols P1 and P2.

Here, the second protocol P2 is a protocol that can reduce the power consumption of the handset 20 compared to the first protocol P1, and can adopt, for example, Bluetooth (registered trademark), that is, the IEEE standard "802.15.1." Also, the first protocol P1 is a protocol that allows the base device 10 to detect the position of the child device 20, and for example, UWB (Ultra Wide Band), that is, the IEEE standard "802.15.4z" can be adopted. Child device 20 stores identification information IDC (see FIG. 3) for identifying child device 20, and child device 20 transmits identification information IDC to parent device 10 by first protocol P1.

In FIG. 1 , the narrow management area 50 (first area) is the area near the door 82 . Also, the wide area management area 40 (second area) is a wider area including the narrow area management area 50 . The wide area management area 40 and the narrow area management area 50 may be set based on the distance from the main unit antenna 12 . In other words, it is preferable to test-operate the mobile monitoring system 1 in a stage prior to the actual operation of the mobile monitoring system 1, and to set appropriate ranges for the wide area management area 40 and the narrow management area 50 based on the conditions for using the mobile monitoring system 1. Further, the base unit antenna 12 preferably has directivity, and is preferably installed facing the wide area management area 40 .

Further, the sensor unit 14 detects the position and shape of the moving body 30 in the same range as the wide area management area 40 (although there may be some differences). A LiDAR (Light Detection and Ranging) sensor, for example, is preferably applied to the sensor unit 14 . However, the position and shape of the moving body 30 may be calculated by applying a monitoring camera or the like as the sensor unit 14 and analyzing the captured image data.

The lock/unlock device 84 locks, unlocks, opens, and closes the door 82 based on commands from the control unit 60 . The control unit 60 includes a registration information storage unit 62, a registration information acquisition unit 64, a mobile unit identification unit 66 (mobile unit identification process), a mobile unit position management unit 68 (mobile unit position management process), and a door control unit 70 (door control process).

The registration information storage unit 62 stores part of the identification information IDC described above as registration information IDR (see FIG. 3) that permits opening and unlocking of the door 82 . The registration information acquisition unit 64 acquires the registration information IDR from the registration information storage unit 62 . Based on the detection result of the sensor section 14, the mobile body position management section 68 detects and manages the position of each mobile body 30 in the wide area management area 40 (including the narrow area management area 50). The moving object identification unit 66 classifies the moving object 30 into one of a plurality of types based on the position of each moving object 30 detected by the moving object position management unit 68, the position of each slave unit 20, and the like. The door control unit 70 outputs commands for locking, unlocking, opening, and closing the door 82 to the lock/unlock device 84 based on the position of each moving body 30 and the like.

FIG. 2 is a block diagram of computer 980 . The control unit 60 shown in FIG. 1 includes one or more computers 980 shown in FIG.
In FIG. 2, computer 980 includes CPU 981 , storage unit 982 , communication I/F (interface) 983 , input/output I/F 984 and media I/F 985 . Here, the storage unit 982 includes a RAM 982a, a ROM 982b, and an HDD 982c. Communication I/F 983 is connected to communication circuit 986 . The input/output I/F 984 is connected to the input/output device 987 . A media I/F 985 reads and writes data from a recording medium 988 . The ROM 982b stores an IPL (Initial Program Loader) and the like executed by the CPU. The HDD 982c stores control programs, various data, and the like. The CPU 981 implements various functions by executing control programs and the like loaded from the HDD 982c into the RAM 982a. The inside of the control unit 60 previously shown in FIG. 1 shows functions implemented by a control program or the like as blocks.

<Operation of the first embodiment>
Next, the operation of this embodiment will be described.
Child device 20 continuously transmits pairing information according to second protocol P2 and attempts communication with parent device 10 regardless of whether it is located inside or outside wide area management area 40 . In this way, the slave device 20 constantly transmits the pairing information in the second protocol P2, so as described above, the second protocol P2 is preferably a protocol with low power consumption.

Then, when the child device 20 enters the wide area management area 40, the parent device 10 responds to the pairing information, and the pairing between the parent device 10 and the child device 20, that is, the second wireless communication by the second protocol P2 is established. Next, master device 10 starts first wireless communication with slave device 20 according to first protocol P1. As a result, master device 10 can detect the position of slave device 20 in wide area management area 40, that is, the position of corresponding mobile object 30 with high accuracy.

When the mobile object 30 enters the wide area management area 40, the mobile object identification unit 66 classifies the mobile object 30 as a registered mobile object 30A, a class 1 unregistered mobile object 30B, or a class 2 unregistered mobile object 30C. The first class unregistered mobile object 30B and the second class unregistered mobile object 30C may be collectively referred to as "unregistered mobile bodies 30B and 30C". In the example of FIG. 1, the mobile body 30-1 is the registered mobile body 30A, the mobile body 30-2 is the first class unregistered mobile body 30B, and the mobile body 30-3 is the second class unregistered mobile body 30C. These classifications are described below.

(Registered moving body 30A)
If the mobile unit 30 is equipped with the mobile unit 20 and the mobile unit 20 is registered in the registration information storage unit 62, the mobile unit 30 is the registered mobile unit 30A. The mobile unit position management unit 68 determines that the mobile unit 30 is equipped with the mobile unit 20 if any mobile unit 20 is positioned inside the outer edge of the three-dimensional area occupied by the mobile unit 30 in the space. Further, when any child device 20 is not located within the outer edge of any mobile device 30, the mobile device position management unit 68 determines that the mobile device 30 closest to the child device 20 is equipped with the child device 20.

As described above, when mobile unit 30 equipped with child device 20 enters wide area management area 40 , the second wireless communication is established between master device 10 and child device 20 . After the second wireless communication is established, the first wireless communication is established between the master device 10 and the slave device 20 . The mobile unit identification unit 66 acquires the identification information IDC from the child device 20 via the base device 10 by the first wireless communication. Further, the registration information acquisition unit 64 reads the mobile unit identification unit 66 and acquires the registration information IDR.

The mobile identification unit 66 collates the acquired identification information IDC with each piece of registration information IDR. Then, when the identification information IDC matches any registration information IDR, the mobile identification unit 66 identifies the child device 20 as the registered child device 20A registered in the control unit 60 . Further, the mobile unit identification unit 66 identifies the mobile unit 30 equipped with the registered slave unit 20A as the registered mobile unit 30A. After that, the mobile unit location management unit 68 uses the first wireless communication to detect the location of the registered slave unit 20A in the wide area management area 40 and the narrow area management area 50, and based on this, detects and manages the location of the registered mobile unit 30A.

FIG. 3 is a diagram schematically showing the matching operation of the identification information IDC in the control section 60. As shown in FIG.
First, a plurality of pieces of registration information IDR are stored in the registration information storage section 62 of the control section 60 . The registration information IDR is a combination of letters, numbers, etc., and is unique. The mobile unit identification unit 66 (see FIG. 1) of the control unit 60 acquires the identification information IDC from the handset 20 . In the illustrated example, it is assumed that the identification information IDC is "XXX003". A plurality of pieces of registration information IDR stored in the registration information storage unit 62 include "XXX003" which is the same as this identification information IDC. Accordingly, the mobile unit identification unit 66 identifies the mobile unit 20 as the registered mobile unit 20A, and identifies the mobile unit 30 (see FIG. 1) equipped with the registered mobile unit 20A as the registered mobile unit 30A.

(Type 1 unregistered mobile object 30B)
As described above, when mobile unit 30 equipped with child device 20 enters wide area management area 40 , the second wireless communication is established between master device 10 and child device 20 . Then, when the second wireless communication is established, the first wireless communication is established between the master device 10 and the slave device 20 . The control unit 60 tries to acquire the identification information IDC from the slave device 20 through the first wireless communication via the master device 10, but there are cases where the identification information IDC cannot be acquired in the first place.

Further, even if the identification information IDC can be acquired, the identification information IDC may not be included in the registration information IDR stored in the registration information storage unit 62 . In such a case, the mobile identification unit 66 identifies the child device 20 as an unregistered child device 20B, and identifies the mobile device 30 equipped with the unregistered child device 20B as a type 1 unregistered mobile device 30B. After that, the mobile unit location management unit 68 uses the first wireless communication to detect the location of the unregistered handset 20B in the wide area management area 40 and the narrow area management area 50, and based on this, detects and manages the location of the type 1 unregistered mobile unit 30B.

(Second class unregistered mobile object 30C)
Also, when a moving body 30 not equipped with a handset 20 enters the wide area management area 40 , the sensor unit 14 detects the presence of the moving body 30 . In this case, since there is no slave device 20 that can be paired with the base device 10, the mobile unit identification unit 66 identifies the mobile unit 30 as a type 2 unregistered mobile unit 30C. After that, based on the detection result by the sensor unit 14, the mobile unit position management unit 68 detects the location of the type 2 unregistered mobile unit 30C in the wide area management area 40 and the narrow area management area 50, and monitors movement by managing them.

When any mobile body 30 enters the narrow area management area 50, the mobile body position management section 68 supplies the door control section 70 with information to that effect and the type of the mobile body 30 (registered mobile body 30A or non-registered mobile bodies 30B, 30C). The door control unit 70 automatically unlocks and opens the door 82 when the registered mobile object 30A is located in the narrow area management area 50 and neither of the unregistered mobile objects 30B, 30C is located within the narrow area management area 50.

On the other hand, when the registered mobile unit 30A is located in the narrow area management area 50 and one of the non-registered mobile units 30B and 30C is located in the narrow area management area 50, the door control unit 70 controls the lock/unlock device 84 to unlock and open the door 82 on condition that a predetermined operation is performed in the registered mobile unit 20A of the registered mobile unit 30A. More specifically, when a predetermined operation is performed in the registered slave device 20A, an unlock command signal is output to the door controller 70 of the controller 60 via the master device 10 from the registered slave device 20A. Based on this unlock command signal, the door control unit 70 causes the lock/unlock device 84 to unlock and open the door 82 .

If the door 82 is not automatically unlocked even though the registered mobile body 30A is located in the narrow management area 50, it means that one of the non-registered mobile bodies 30B and 30C is located in the narrow management area 50.例文帳に追加The fact that the unregistered mobile bodies 30B and 30C are close to the door 82 means that there is a possibility of tailgating that the unregistered mobile bodies 30B and 30C pass through the door 82 together with the registered mobile body 30A. As a result, the registered mobile body 30A can recognize the possibility of tailgating, and can prevent tailgating by unlocking and opening the door 82 while paying attention to the surroundings.

[Second embodiment]
<Configuration of Second Embodiment>
FIG. 4 is a schematic diagram of a mobile monitoring system 2 according to the second embodiment. In the following description, parts corresponding to those in the first embodiment described above are denoted by the same reference numerals, and description thereof may be omitted.
The moving body monitoring system 2 is a system for monitoring moving bodies 30 entering and leaving the restricted area 300 . The restricted area 300 is a private residence, an apartment complex, a business office, a warehouse for storing articles, or the like. Also, the outside of the restricted area 300 is called an external area 200 .

By the way, there is a high possibility that the moving object 30 approaching the door 82 in the external area 200 is about to enter the restricted area 300 . Therefore, the external area 200 is sometimes referred to as the "entrance side". In addition, there is a high possibility that the moving body 30 approaching the door 82 in the restricted area 300 is about to leave the restricted area 300 . Therefore, the restricted area 300 is sometimes referred to as the "exit side".

The mobile monitoring system 2 includes a base unit 10, a base unit antenna 12, a sensor unit 14, a control unit 60, a door 82, and a locking/unlocking device 84, as in the mobile monitoring system 1 of the first embodiment.

However, the mobile object monitoring system 2 has the master unit antenna 12 and the sensor unit 14 on both the entrance side and the exit side. Here, the entrance-side parent device antenna 12 and the sensor unit 14 are referred to as an entrance-side parent device antenna 212 and an entrance-side sensor unit 214, respectively. The wide-area management area 40 and the narrow-area management area 50 on the entrance side are called an entrance-side wide-area management area 240 (second entrance-side area) and an entrance-side narrow-area management area 250 (first entrance-side area), respectively. Also, the exit-side parent device antenna 12 and the sensor unit 14 are referred to as an exit-side parent device antenna 312 and an exit-side sensor unit 314, respectively. Also, the wide-area management area 40 and the narrow-area management area 50 on the exit side are called an exit-side wide-area management area 340 (second exit-side area) and an exit-side narrow-area management area 350 (first exit-side area), respectively.

In this embodiment as well, the mobile device 30 may or may not be equipped with the slave device 20 . Then, the master device 10 and the slave device 20 perform the second wireless communication and the first wireless communication on both the entrance side and the exit side. That is, master device 10 communicates with slave devices 20 located in entry-side wide-area management area 240 and exit-side wide-area management area 340 using first and second protocols P1 and P2.

Here, the entrance-side narrow area management area 250 is an area around the door 82 and is part of the entrance-side wide area management area 240 . Similarly, the exit side narrow management area 350 is an area around the door 82 and is part of the exit side wide management area 340 . In this embodiment, among the registered mobile bodies 30A, those positioned on the entrance side are referred to as entrance side registered mobile bodies 230A, and those positioned on the exit side are referred to as exit side registered mobile bodies 330A.

Similarly, among the type 1 unregistered moving bodies 30B, those located on the entrance side are called type 1 entrance side unregistered moving bodies 230B (entrance side unregistered moving bodies), and those located on the leaving side are called type 1 exit side unregistered moving bodies 330B. Similarly, among the type 2 unregistered moving bodies 30C, those located on the entrance side are called type 2 entrance side unregistered moving bodies 230C (entrance side unregistered moving bodies), and those located on the exit side are called type 2 exit side unregistered moving bodies 330C.

When a moving object 30 equipped with a child device 20 enters an entrance-side wide area management area 240 and second radio communication is established between the master device 10 and the child device 20, the master device 10 starts the first radio communication with the child device 20.例文帳に追加Then, master device 10 tries to acquire identification information IDC from slave device 20 . When the identification information IDC can be acquired from the child device 20 and the identification information IDC is included in the registration information IDR stored in the registration information storage unit 62, the mobile unit identification unit 66 identifies the child device 20 as the registered child device 20A, and monitors the movement of the mobile unit 30 equipped with it as the entrance side registered mobile unit 230A.

In addition, when the identification information IDC cannot be obtained from the child device 20 in the mobile device 30 in the entry-side wide area management area 240, or when the obtained identification information IDC is not included in the registration information IDR, the mobile device identification unit 66 identifies the child device 20 as an unregistered device 20B, identifies the mobile device 30 equipped with the child device 20 as a type 1 entry-side non-registered mobile device 230B, and the mobile device location management unit 68 monitors its movement. Also, when a moving body 30 not equipped with a handset 20 enters the entrance side wide area management area 240, the moving body identification unit 66 identifies the moving body 30 as a type 2 entrance side non-registered moving body 230C, and the moving body position management part 68 monitors its movement.

Further, when the moving body 30 equipped with the child device 20 enters the exit side wide area management area 340 and the second wireless communication is established between the master device 10 and the slave device 20, the master device 10 starts the first wireless communication with the slave device 20.例文帳に追加Then, master device 10 tries to acquire identification information IDC from slave device 20 . When the identification information IDC can be obtained from the child device 20 and is included in the registration information IDR stored in the registration information storage unit 62, the mobile unit identification unit 66 identifies the child unit 20 as the registered child unit 20A, identifies the mobile unit 30 equipped with this as the exit side registered mobile unit 330A, and the mobile unit position management unit 68 monitors the movement thereof.

In addition, when the identification information IDC cannot be obtained from the child device 20 in the mobile device 30 in the exit-side wide-area management area 340, or when the identification information IDC that has been obtained is not included in the registration information IDR, the mobile device identification unit 66 identifies the child device 20 as an unregistered device 20B, identifies the mobile device 30 equipped with the child device 20 as a type 1 exit-side non-registered mobile device 330B, and the mobile device position management unit 68 monitors its movement. In addition, when a mobile body 30 not equipped with a handset 20 enters the exit side wide area management area 340, the mobile body identification unit 66 identifies the mobile body 30 as a type 2 exit side unregistered mobile body 330C, and the mobile body position management unit 68 monitors its movement.

<Operation of Second Embodiment>
(preset)
In the moving object monitoring system 2 of the present embodiment, when the moving object 30 attempts to move from the entrance side to the exit side, or from the exit side to the entrance side, the control unit 60 determines whether the move is appropriate and locks or unlocks the door 82. In the test operation, which is the stage prior to the actual operation of the mobile object monitoring system 2, the worker makes the following preparations.
(1) The entry-side wide-area management area 240 and the entry-side narrow-range management area 250 are set as communication ranges for the second wireless communication of the base unit 10 via the entrance-side base unit antenna 212 .

(2) Further, the detection range of the entrance-side sensor unit 214 is set within the same range as the entrance-side wide-area management area 240 (a slight error may be allowed).
(3) Set exit-side wide-area management area 340 and exit-side narrow-area management area 350 as a communication range for master unit 10 to perform second wireless communication via exit-side master unit antenna 312 .
(4) Further, the detection range of the exit-side sensor unit 314 is set within the same range as the exit-side wide-area management area 340 (a slight error may be allowed).

(5) Store one or more pieces of registration information IDR in the registration information storage unit 62 of the control unit 60 . When storing a plurality of pieces of registration information IDR, each piece of registration information IDR is unique and non-duplicated.
(6) Select one or a plurality of stored registration information IDR, and set each registration information IDR as the identification information IDC of the same number of child devices 20 to be permitted to enter/exit the restricted area 300 . As a result, these child devices 20 become registered child devices 20A permitted to enter and leave the restricted area 300. FIG.
(7) An unlocking command means is set in the registration slave device 20A so that the registration slave device 20A can transmit an unlocking command signal for commanding the unlocking operation to the lock/unlock device 84 via the door control unit 70 . This unlock command means may be hardware (for example, a button and a transmission circuit) installed in the registration slave device 20A, or may be software (for example, icon + communication function of the terminal).

(operation of this operation)
Next, the operation of the mobile monitoring system 2 in this operation will be described.
In addition, in the following description, the operation when the moving body 30 moves from the outside area 200 to the restricted area 300 will be mainly described. When the moving object 30 moves from the restricted area 300 to the external area 200, the operations are similar, for example, "entering" and "exiting" are switched, so the explanation is omitted.

(1) Assume that the mobile device 30 is equipped with the slave device 20 . The child device 20 always transmits pairing information by the second protocol P2. Here, when the mobile unit 30 enters the entry-side wide-area management area 240, pairing is established between the master device 10 and the slave device 20, and the second wireless communication is established. After that, the first wireless communication is established between the master device 10 and the slave device 20 according to the first protocol P1.

In the first protocol P1, the parent device 10 receives the identification information IDC from the child device 20. FIG. It is assumed that this identification information IDC matches any registration information IDR stored in the registration information storage unit 62 . Then, the moving object identification unit 66 identifies the child device 20 as the registered child device 20A, and identifies the mobile device 30 equipped with the registered child device 20A as the entry side registered mobile body 230A. Then, the mobile unit position management section 68 manages the positions of the registered slave unit 20A and the entrance-side registered mobile unit 230A by the first wireless communication, and monitors their movements.

Further, when the master device 10 cannot acquire the identification information IDC that matches any of the registration information IDR from the slave device 20, the mobile unit identification unit 66 identifies the slave device 20 as the unregistered slave unit 20B, and identifies the mobile unit 30 equipped with the unregistered slave unit 20B as the first type entry side unregistered mobile unit 230B.

In this case, the door control unit 70 does not unlock the door 82 until an unlock command signal is supplied from the registration slave device 20A.

On the other hand, when the unlock command means in the registration slave device 20A is operated and an unlock command signal is supplied to the door control unit 70 via the master device 10, the door control unit 70 transmits the unlock signal to the lock/unlock device 84 to unlock the door 82. Further, the lock/unlock device 84 may automatically open the door 82 . That is, the registered mobile unit 30A permitted to enter and exit the restricted area 300 can operate the registered slave unit 20A to permit tailgating. Here, it is assumed that both the entry side registered mobile body 230A and the type 1 entry side unregistered mobile body 230B or the type 2 admission side unregistered mobile body 230C move to the exit side wide area management area 340. FIG. When the door control unit 70 confirms that both of them have moved to the exit side wide area management area 340, the door control unit 70 automatically closes and locks the door 82 by transmitting a lock signal to the lock/unlock device 84.

The above-described embodiments are exemplified for easy understanding of the present invention, and are not necessarily limited to those having all the described configurations. Also, part of the configuration of one embodiment can be replaced with the configuration of another embodiment, and the configuration of another embodiment can be added to the configuration of one embodiment. Also, it is possible to delete part of the configuration of each embodiment, or to add or replace other configurations. Also, the control lines and information lines shown in the drawings are those considered to be necessary for explanation, and do not necessarily show all the control lines and information lines necessary on the product. In practice, it may be considered that almost all configurations are interconnected. Possible modifications to the above embodiment are, for example, the following.

(1) In each of the above embodiments, non-registered mobile bodies other than the registered mobile body 30A are classified into the type 1 non-registered mobile body 30B and the type 2 non-registered mobile body 30C. However, by classifying unregistered mobile bodies into the first class unregistered mobile body 30B and the second class unregistered mobile body 30C as in the above embodiment, there is an advantage that the identification and management of the unregistered mobile bodies are facilitated. For example, when a large number of unregistered moving bodies are concentrated, it may be difficult to distinguish individual unregistered moving bodies based only on the detection results of the sensor unit 14 . In such a case, by managing at least part of the non-registered mobile bodies as the first type non-registered mobile bodies 30B, it is possible to discriminate them from other mobile bodies 30, so that individual non-registered mobile bodies can be precisely discriminated.

The reason for this is that the slave device 20 always transmits the pairing information according to the second protocol P2, so that the power consumption for that purpose is reduced. However, if there is no particular need to consider the power consumption of the child device 20, the second protocol P2 may not be used. That is, the slave device 20 may always transmit the pairing information using the first protocol P1.

(3) Since the hardware of the control unit 60 in the above embodiment can be realized by a general computer, the programs and the like for executing the various processes described above may be stored in a storage medium (a computer-readable recording medium on which the program is recorded) or distributed via a transmission path.

(4) Each of the processes described above has been described as software processing using a program in the above embodiment, but part or all of it may be replaced with hardware processing using an ASIC (Application Specific Integrated Circuit), FPGA (Field Programmable Gate Array), or the like.

(5) The registration information storage unit 62 may be placed in a cloud or the like on a network (not shown), and may not be included in the control unit 60 .
