[0004] As in Patent Document 1, in police operations and the like, there is a need for secure data transmission between devices mounted on vehicles and computers for business systems at headquarters or bases. One possible method for exchanging this data is to transmit it via a wireless LAN (Local Area Network) or the like. However, because the radio waves of a typical wireless LAN are adjusted to pick up as many radio waves as possible within the scope of regulations such as the Radio Law, there is a risk of eavesdropping. Furthermore, because image and video data and the like are large in size, problems arise in that using a wide-area communication network such as a Long Term Evolution (LTE) line as in Patent Document 1 takes a long time and places a load on the wide-area communication network.

DETAILED DESCRIPTION OF THE INVENTION

[0012] First, an overview of one embodiment of the present disclosure will be described with reference to the drawings. Note that the reference numerals in this overview are added to each element for convenience as an example to facilitate understanding, and are not intended to limit the present disclosure to the illustrated form. Furthermore, connecting lines between blocks in the drawings and the like referred to in the following description include both bidirectional and unidirectional lines. Unidirectional arrows are used to schematically indicate the flow of main signals (data) and do not exclude bidirectionality. A program is executed via a computer device, which includes, for example, a processor, a storage device, an input device, a communication interface, and, if necessary, a display device. Furthermore, this computer device is configured to be able to communicate with internal or external devices (including computers) via the communication interface, whether wired or wireless. Furthermore, ports or interfaces are present at the input / output connection points of each block in the drawings, but are not shown.

[0013] In one embodiment, the present disclosure can be realized in a configuration including a terminal 10 of a business system and a communication device 20, as shown in Fig. 1. More specifically, the terminal 10 of the business system includes a first antenna 11 and a wireless communication unit 12. The first antenna 11 is installed in a space where a mobile object V is to be positioned, and is installed so that the distance from a second antenna 21 on the mobile object V side is equal to or less than a predetermined value when the mobile object V is positioned in a normal position in the space. The wireless communication unit 12 performs a communication function with a communication device 20 mounted on the mobile object V, which includes a second antenna 21 installed opposite the first antenna 11.

[0014] The communication device 20 includes a second antenna 21, a communication unit 22, and a relay unit 23. The second antenna 21 is installed on the mobile object V in a space where the mobile object V is positioned, such that the distance between the second antenna 21 and the first antenna 11 installed in the space is equal to or less than a predetermined value when the mobile object V is positioned in a normal position in the space. The communication unit 22 performs wireless communication using the second antenna 21 with a business system terminal 10 connected to the first antenna 11 when the mobile object V is positioned in the normal position in the space. The relay unit 23 relays communication between the business system terminal 10 and a device 24 installed on the mobile object V. Examples of the device 24 include an in-vehicle camera, a tablet terminal, a passenger's smartphone, a digital camera, and a sound-collecting microphone. The in-vehicle camera may also be a 360-degree camera capable of capturing images of the surroundings of the mobile object.

[0015] The terminal 10 and communication device 20 of the business system configured as described above operate as shown in Fig. 2. First, at least one of the terminal 10 and communication device 20 of the business system detects that the mobile object V has been positioned in the correct position in the space where the first antenna 11 is installed (step S11).

[0016] Next, the terminal 10 of the business system and the communication device 20 start communication (step S12). Specifically, when the mobile body is located in the normal position, the distance between the first antenna 11 installed in the space and the second antenna 21 installed in the mobile body V becomes equal to or less than a predetermined value. In this state, communication starts between the device 24 mounted on the mobile body and the terminal 10 of the business system connected to the first antenna 11 via the first and second antennas.

[0017] The operation of the terminal 10 and communication device 20 of the business system will be described in detail with reference to Figures 3 and 4. Figure 3 shows the process of a mobile object V moving backward toward its normal position in the space where it is to be positioned. In the state of Figure 3, the distance L between the first antenna 11 and the second antenna 21 exceeds the threshold value at which they can communicate with each other, and therefore communication is not possible.

[0018] 4 shows a state in which the mobile object V is located in the normal position in the space. In the state shown in FIG. 4, the distance L between the first antenna 11 and the second antenna 21 is equal to or less than the threshold value at which they can communicate with each other, enabling communication between the wireless communication unit 12 and the communication unit 22. In this state, the relay unit 23 relays communication between the terminal 10 of the business system and the device 24 mounted on the mobile object V.

[0019] The communication distance between the terminal 10 of the business system and the communication device 20 can be adjusted by the transmission power of the radio waves transmitted by the first antenna 11 and the second antenna 21. If a high level of security is required for data exchanged between the terminal 10 of the business system and the communication device 20, the transmission power is reduced. This narrows the range considered to be the authorized location, thereby reducing the risk of data leakage. Conversely, if a high level of security is not required for data exchanged between the terminal 10 of the business system and the communication device 20, the transmission power can be set to a larger value. This widens the range considered to be the authorized location, thereby improving user convenience.

[0020] 1 to 4, the mobile object V is a vehicle. However, as shown in FIG. 5, the mobile object V may be an unmanned airplane. Similarly, in the configuration of FIG. 5, when the distance L between the first antenna 11 and the second antenna 21a is equal to or less than a communication threshold, communication between the wireless communication unit 12 and the communication unit 22a becomes possible. In this state, the relay unit 23a relays communication between the terminal 10 of the business system and a device 24a, such as a camera, mounted on the mobile object V. As shown in FIGS. 3 and 4, in the case of either a vehicle or an unmanned airplane, the second antenna 21, 21a may be installed on the bottom or side of the vehicle or aircraft.

[0021] [First embodiment] Next, a first embodiment in which the present disclosure is applied to data transmission and reception between a police station's business system and a camera-equipped terminal mounted on a patrol car will be described in detail with reference to the drawings.

[0022] Fig. 6 is a diagram showing a first configuration of the present disclosure. Referring to Fig. 6, the police station grounds where a building (office building) 300 and a parking lot 400 are installed are shown.

[0023] Parking lot 400 is provided with parking space PS. In parking space PS, antenna unit 101 is installed at a position that faces antenna unit 201 on the side of patrol car PC when patrol car PC is parked in a specified position. This antenna unit 101 is connected to PC 102 via network device 103. Antenna unit 201 may be installed on the paved surface of parking space PS, or may be embedded in the paved surface of parking space PS. This antenna unit 101 corresponds to the first antenna 11 described above.

[0024] In addition, a sensor 104 is installed near the parking space PS to detect the entry of a patrol car PC into the parking space PS. When the sensor 104 detects that the patrol car PC has entered, it sends an entry signal to the PC 102. This sensor 104 may be, for example, an infrared sensor or a footboard sensor. Alternatively, a license plate reader or the like may be used as the sensor 104.

[0025] A personal computer 102 for the police station's business system and network devices 103 such as hubs and switches are installed in a building (office building) 300. This personal computer 102 (hereinafter referred to as "PC 102") corresponds to the "business system terminal" described above.

[0026] When the PC 102 receives an approach signal from the sensor 104, it issues a command to the antenna unit 101 to transmit radio waves.

[0027] The PC 102, the network device 103, the sensor 104, and the antenna unit 101 are connected to each other via a wired LAN (Local Area Network).

[0028] An antenna unit 201 is installed on the underside of the body of the patrol car PC. This antenna unit 201 is installed so that when the patrol car PC is parked in a specified position in the parking space PS, the antennas of the antenna unit 201 and the antenna unit 101 of the parking space PS face each other and are closest to each other. At this time, the distance between the two antennas is closest, about several tens of centimeters. This enables communication between the antenna unit 101 and the antenna unit 201. Note that a VPN (Virtual Private Network) connection is used to ensure security when connecting the antenna unit 101 and the antenna unit 201. Note that the installation location of the antenna unit 201 is not limited to the underside of the body. For example, the antenna unit 201 can also be installed under a seat.

[0029] The patrol car PC is also equipped with a tablet terminal 203 equipped with a camera for taking photos and videos of the scene, etc. This tablet terminal corresponds to the device described above. The tablet terminal 203 can be connected to the vehicle's antenna unit 101 via a LAN cable or the like. Note that the connection between the tablet terminal 203 and the antenna unit 201 does not have to be via a LAN cable. For example, if the antenna unit 201 is provided with a USB port, the tablet terminal 203 and the antenna unit 201 may be connected using a USB cable.

[0030] 1. Therefore, the antenna unit 201 corresponds to the second antenna 21, the communication unit 22, and the relay unit 23 described above. The antenna unit 201 cannot communicate when there is no partner with which to handshake. Therefore, when there is no partner with which to handshake, the antenna unit 201 cannot transmit business data including video data and audio data stored in the tablet terminal 203.

[0031] The transmission power of the radio waves from antenna unit 201 and antenna unit 101 is set to a level that allows communication by short-range wireless communication when the distance between the two antennas is within a predetermined value (for example, within a distance of several tens of centimeters). In other words, the output of antenna unit 201 and antenna unit 101 is adjusted so that data cannot be transmitted when the distance between the antennas exceeds a predetermined value.

[0032] Next, the operation of this embodiment will be described in detail with reference to the drawings. Fig. 7 is a sequence diagram showing the operation of the first configuration of the present disclosure. Referring to Fig. 7, first, when the patrol car PC enters the parking space PS, the PC 102 receives an entry signal from the sensor 104 (step S001).

[0033] Next, the PC 102 issues a start-up command to the antenna unit 101 to transmit radio waves (step S002). As a result, the antenna unit 101 emits radio waves.

[0034] Meanwhile, the antenna unit 201 on the vehicle side is activated at a predetermined timing, such as when the shift lever is moved to the parking position, and emits radio waves (step S003). The activation timing of the antenna unit 201 is not limited to when the shift lever is moved to the parking position. For example, a switch for activating the antenna unit 201 may be provided, and the antenna unit 201 may be activated when the switch is turned on.

[0035] When the antenna unit 101 and the antenna unit 201 are activated and communication between them is established (step S004), data is transmitted from the tablet terminal 203 on the vehicle side to the PC 102 (step S005).

[0036] The PC 102 saves the data received from the tablet terminal 203 (step S005). When the data saving is complete, the PC 102 instructs both antennas to stop transmitting radio waves. This ends communication between the two.

[0037] As described above, according to the present disclosure, by simply parking the patrol car PC in a specified parking space PS and moving the shift lever to the parking position, the safe transfer of various data recorded on the tablet terminal 203 is completed. Furthermore, since there is no need to remove the tablet terminal 203 from the patrol car PC, it is also possible to prevent the tablet terminal 203 from being lost or forgotten.

[0038] In the above embodiment, the trigger for starting data transmission from the tablet terminal 203 to the PC 102 is described as being automatic, but in order to further enhance security, some kind of ID / password authentication or two-step authentication may be introduced.

[0039] Furthermore, according to the present disclosure, in the wireless section where security is a concern, short-range wireless communication of about several tens of centimeters is used, so radio waves from antenna unit 101 do not reach the vicinity of the patrol car PC or the building. Also, since the parking lot itself is on the grounds of the police station, it is difficult for suspicious persons to peer into the vicinity of the patrol car PC. By adopting such a configuration, the present disclosure ensures physical security even in the wireless section.

[0040] [Second embodiment] Furthermore, in the above embodiment, an example has been described in which data is transmitted from the tablet terminal 203 to the PC 102, but the present disclosure can also be applied to data transmission from the PC 102 to the tablet terminal 203.

[0041] Fig. 8 is a sequence diagram showing the operation of another configuration of the present disclosure. The first difference from the operation shown in Fig. 7 is that after communication between antenna unit 101 and antenna unit 201 is established, data is transmitted from PC 102 to tablet terminal 203 (step S105). The second difference from the operation shown in Fig. 7 is that thereafter, tablet terminal 203 stores the received data (step S106). The other operations are the same as those in the first embodiment, and therefore description thereof will be omitted.

[0042] Depending on the task of the patrol car PC, there may be cases where it is desirable to receive data necessary for investigations or surveys from the business system and carry it to the scene. According to this embodiment, even in such a situation where the patrol car PC is dispatched, data can be transmitted safely and efficiently.

[0043] Although the embodiments of the present disclosure have been described above, the present disclosure is not limited to the above-described embodiments, and further modifications, substitutions, and adjustments can be made without departing from the basic technical concept of the present disclosure. For example, the network configuration, element configuration, and data representation format shown in each drawing are examples to aid in understanding the present disclosure, and are not limited to the configurations shown in these drawings.

[0044] For example, in each of the above-described embodiments, an example has been described in which data is sent from the tablet terminal 203 mounted on the patrol car PC, but the camera-equipped device is not limited to the tablet terminal 203. For example, the present disclosure can of course also be applied to the transfer of data stored in a drive recorder mounted on the patrol car PC or an in-vehicle terminal.

[0045] For example, in the above-described embodiments, the sensor 204 detects the entry of a patrol car PC, and the PC 202 activates the antenna unit 101. However, the user of the PC 202 may manually activate the antenna unit 101. Furthermore, the antenna unit 101 may be activated from the patrol car PC side after introducing a necessary authentication procedure.

[0046] (About hardware configuration) In each embodiment of the present disclosure, each component of each device represents a functional block. Some or all of the components of each device are realized by any combination of an information processing device 900 and a program, for example, as shown in Fig. 9. Fig. 9 is a block diagram showing an example of the hardware configuration of the information processing device 900 that realizes each component of each device. As an example, the information processing device 900 includes the following configuration. ·CPU(Central Processing Unit)901 ROM (Read Only Memory) 902 ·RAM(Random Access Memory)903 Program 904 loaded into RAM 903 A storage device 905 for storing a program 904 A drive device 907 for reading and writing data from and to the recording medium 906 A communication interface 908 for connecting to a communication network 909 Input / output interface 910 for inputting and outputting data Bus 911 connecting each component

[0047] Each component of each device in each embodiment is realized by the CPU 901 acquiring and executing a program 904 that realizes the function. That is, the CPU 901 in FIG. 9 executes a startup program and a communication control program for the antenna unit, and performs an update process for each calculation parameter stored in the RAM 903, the storage device 905, or the like. The program 904 that realizes the function of each component of each device is stored in the storage device 905 or the ROM 902 in advance, for example, and is read out by the CPU 901 as needed. The program 904 may be supplied to the CPU 901 via the communication network 909, or may be stored in advance on the recording medium 906, and the drive device 907 may read out the program and supply it to the CPU 901.

[0048] There are various variations in the method of realizing each device. For example, each device may be realized by any combination of a separate information processing device 900 and a program for each component. Furthermore, multiple components of each device may be realized by any combination of a single information processing device 900 and a program. In other words, the functions of the communication devices and terminals shown in FIG. 1 and subsequent drawings can be realized by a computer program that causes a processor installed in each device to execute the above-described processes using its hardware.

[0049] In addition, some or all of the components of each device may be realized by other general-purpose or dedicated circuits, processors, etc., or a combination of these. These may be configured by a single chip, or by multiple chips connected via a bus.

[0050] Some or all of the components of each device may be realized by a combination of the above-mentioned circuits and programs.

[0051] When some or all of the components of each device are realized by multiple information processing devices, circuits, etc., the multiple information processing devices, circuits, etc. may be centrally or decentralized.
