  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Note that, in the following embodiments, the same reference numerals are given to configurations showing similar functions.

  As shown in FIG. 1, a plurality of wireless communication devices 1 (1-1 to 1-n) are configured to be capable of wireless communication with a command station 5 and a public wireless line via a public network base station 4. Yes. Each wireless communication device 1 includes an in-vehicle wireless device 2 (2-1 to 2-n) and an operation terminal 3 (3-1 to 3-n). The in-vehicle wireless device 2 is installed in a vehicle such as an automobile. The operation terminal 3 is a handset or the like, and is configured to be separable from the in-vehicle wireless device 2. The operation terminal 3 is assigned for each crew member (user), and the crew member operates the in-vehicle wireless device 2 by connecting the assigned operation terminal 3 to the in-vehicle wireless device 2 of the boarding vehicle in a wired or wireless manner. A voice call or data transmission / reception with the command station 5 can be performed. For example, when a crew member performs work in the vicinity of a parked vehicle such as a garage, a warehouse, or a waiting place, conventionally, in order for the crew member to perform a voice call or data communication, a wireless device different from the in-vehicle wireless device is required. Met. However, according to the wireless communication device 1, the crew can use the operation terminal 3 as a portable wireless device by removing the operation terminal 3.

  Specifically, as illustrated in FIG. 2, the in-vehicle wireless device 2 includes a vehicle information acquisition unit 21, a vehicle information analysis unit 22, a communication control unit 23, a wireless communication unit 24, an authentication unit 25, and authentication. An information storage unit 26 and a terminal connection unit 27 are provided.

  The wireless communication unit 24 has a function of performing wireless communication with the command station 5 via the 3G antenna 62. Wireless communication is performed via the base station 4. The 3G line is an example and may be a public network.

  The terminal connection unit 27 has a function of connecting the operation terminal 3 to the in-vehicle wireless device 2. The terminal connection unit 27 includes a wired connection unit 271, a wireless LAN connection control unit 272, a received electric field strength determination unit 273, and a wireless LAN connection unit 274.

  The wired connection unit 271 has a function of wired connection with the operation terminal 3 via a cable 70 such as a curl cord.

  The wireless LAN connection unit 274 includes a transmission unit 275 and a reception unit 276, and has a function of connecting to the operation terminal 3 through the wireless LAN via the wireless LAN antenna 82.

  The received electric field strength determination unit 273 has a function of measuring the received electric field strength of the signal received from the operation terminal 3 via the receiving unit 276 and determining whether the measured received electric field strength exceeds a predetermined threshold value. . The predetermined threshold is set in advance so as to be a boundary between the received electric field strength inside the vehicle and the received electric field strength outside the vehicle in the vehicle in which the in-vehicle wireless device 2 is installed.

  The wireless LAN connection control unit 272 has a function of controlling the wireless LAN connection between the wireless LAN connection unit 274 and the operation terminal 3 based on the determination result of the received electric field strength determination unit 273. When the received electric field strength of the signal received from the operation terminal 3 exceeds a predetermined threshold, the wireless LAN connection control unit 272 determines that the operation terminal 3 is in the vehicle and transmits the operation terminal 3 via the transmission unit 275. A connection release signal is transmitted to the control terminal 3 so that the wireless LAN connection with the operation terminal 3 is disconnected. This is because the operation terminal 3 is not used as a portable wireless communication device in the vehicle. In this case, the operation terminal 3 needs to be switched to a wired connection via the cable 70. On the other hand, when the received electric field strength of the signal received from the operation terminal 3 is equal to or less than a predetermined threshold, the wireless LAN connection control unit 272 performs control to maintain the wireless LAN connection with the operation terminal 3, and the operation terminal 3 The reception signal from is output to the communication control unit 23.

  For example, as illustrated in FIG. 3, it is assumed that the operation terminals 3-1 to 3-3 are in the wireless LAN connection area 85 of the in-vehicle wireless device 2 and outside the vehicle in which the in-vehicle wireless device 2 is installed. In this case, the received electric field strengths of the received signals from the operation terminals 3-1 to 3-3 are all equal to or less than the predetermined threshold value 86, and the wireless LAN connection control unit 272 maintains the wireless LAN connection with the operation terminal 3. Control. 3 to 5 indicate the interior of the vehicle where the in-vehicle wireless device 2 is installed.

  On the other hand, as shown in FIG. 4, it is assumed that the operation terminal 3-2 is arranged in the vehicle. In this case, the received electric field strength of the received signal from the operation terminal 3-2 exceeds a predetermined threshold value 86. Therefore, the wireless LAN connection control unit 272 transmits a connection release signal to the operation terminal 3-2 and controls to release the wireless LAN connection with the operation terminal 3. Since the other operation terminals 3-1 and 3-3 are within the wireless LAN connection area 85 of the in-vehicle wireless device 2 and are outside the vehicle, they have not received a connection release signal from the wireless LAN connection control unit 272 and continue. Wireless LAN connection with the in-vehicle wireless device 2 is possible.

  As illustrated in FIG. 5, the operation terminal 3-2 that has been disconnected from the wireless LAN connection with the in-vehicle wireless device 2 in response to the connection release signal can be wired to the in-vehicle wireless device 2 via the cable 70.

  The wireless LAN connection control unit 272 acquires a vehicle door opening / closing signal via the vehicle information acquisition unit 21, and the operation terminal 3 is placed in the vehicle based on the determination result of the received electric field strength determination unit 273 and the door opening / closing signal. Reliability may be improved by determining whether the vehicle is outside the vehicle.

  The communication control unit 23 is connected to the vehicle information analysis unit 22, the wireless communication unit 24, the authentication unit 25, and the terminal connection unit 27.

  The communication control unit 23 can control the wireless communication connection order of the operation terminals 3 connected to the terminal connection unit 27 in wireless communication with the command station 5. Specifically, in the terminal connection unit 27, when both the wired connection operation terminal 3 and the wireless LAN connection operation terminal 3 are connected, the communication control unit 23 sets the wired connection operation terminal 3. Is wirelessly communicated with the command station 5 with the highest priority. However, even if the wired-connected operation terminal 3 and the command station 5 perform wireless communication, if there is a vacant wireless communication band, the wireless LAN-connected operation terminal 3 continues to wirelessly communicate with the command station 5. . When there are a plurality of operation terminals 3 connected by wireless LAN, they may be assigned so that the wireless communication connection order becomes higher, for example, in the order of wireless LAN connection or in the order of authentication by the authentication unit 25 described later.

  Further, the communication control unit 23 functions as the authentication / communication switching unit 231, and accepts an operation only from the operation terminal 3 that has been successfully authenticated, among the operation terminals 3 connected to the terminal connection unit 27, via the wireless communication unit 24. Wireless communication with the command station 5 is permitted.

When the authentication is successful, the authentication / communication switching unit 231 notifies the operation terminal 3 that has succeeded in the authentication to the effect that the authentication has been successful, and permits wireless communication between the operation terminal 3 and the command station 5 that have succeeded in the authentication. As a result, the operation terminal 3 that has succeeded in authentication can operate the in-vehicle wireless device 2, and can transmit and receive voice and data to and from the command station 5 through the in-vehicle wireless device 2. On the other hand, if the authentication fails, the authentication / communication switching unit 231 notifies the operation terminal 3 that has failed the authentication via the terminal connection unit 27 and notifies the connection between the operation terminal 3 and the terminal connection unit 27. The operation from the operation terminal 3 is not accepted. For example, the authentication / communication switching unit 231 may manage whether or not each operation terminal 3 connected to the terminal connection unit 27 has been successfully authenticated based on the individual identification number of the operation terminal 3 or the like.

  The authentication unit 25 has a function of performing user authentication by comparing the user information 311 of the operation terminal 3 with a plurality of user information 262 stored in the authentication information storage unit 26. When user information that matches the user information 311 of the operation terminal 3 is stored in the authentication information storage unit 26, authentication is successful, and user information that matches the user information 311 of the operation terminal 3 is stored in the authentication information storage unit 26. If not, authentication fails.

  The authentication information storage unit 26 stores group information 261 and a plurality of user information 262 in association with each other. The group information 261 is a group in which the in-vehicle wireless device 2 is registered, and the plurality of user information 262 is a user ID of each crew member registered in the group. The operation terminal 3 assigned to each crew member stores user information 311 of the crew member. If the crew member is the in-vehicle wireless device 2 of the same group as the group in which the user information 311 is registered, the crew member can use the in-vehicle wireless device 2 by performing user authentication via the assigned operation terminal 3. Yes. This is because the crew's boarding vehicle is not always the same.

The vehicle information analysis unit 22 receives vehicle operation information (speed during driving, travel distance, driving travel time, drive recorder information, door open / close signal, etc.) from an in-vehicle sensor or the like installed in the vehicle via the vehicle information acquisition unit 21. Has a function of acquiring and analyzing appropriately. The vehicle information analysis unit 22 may be provided with a GPS or an acceleration sensor, and may analyze the positional information by GPS or the information such as the vehicle tilt or impact by the acceleration sensor together with the vehicle operation information from the vehicle information acquisition unit 21. Good. The vehicle information analysis unit 22 can also analyze the vehicle operation information transmitted from the command station 5. The vehicle information analysis unit 22 transmits vehicle operation information to the command station 5 and the operation terminal 3 in response to an operation from the operation terminal 3 that has been successfully authenticated. The vehicle operation information may include a vehicle body number of the vehicle and user information 311 stored in the operation terminal 3. Further, in the event of a disaster, the vehicle information analysis unit 22 automatically transmits vehicle operation information to the command station 5 even when the operation terminal 3 is not connected to the in-vehicle wireless device 2, and as information at the time of the disaster You may make it usable. The vehicle may be provided with an in-vehicle sensor that detects a disaster such as a seismometer.
In addition, when the vehicle information analysis unit 22 determines that the vehicle is running based on the position information and acceleration sensor information by GPS, the communication control unit 23 receives the result and sends the result to the wireless LAN connection control unit 272. The wireless LAN connection with the operation terminal 3 may be instructed to be disconnected. Thereby, it can suppress more reliably that the operation terminal 3 is used as a portable radio | wireless telephone apparatus inside a vehicle while driving | running | working a vehicle.

  As shown in FIG. 6, the operation terminal 3 includes a wireless LAN connection unit 32, a wired connection unit 33, a terminal control unit 36, an operation unit 35, a call unit 34, and a user information storage unit 31. Yes.

  The call unit 52 includes a microphone and a speaker, and has a function of inputting and reproducing audio data.

  The storage unit 54 includes a vehicle operation information DB 541 and a registered user information DB 542. The vehicle operation information DB 541 stores identification information of the in-vehicle wireless device 2 installed in the vehicle, group information 261 of the in-vehicle wireless device 2, and vehicle operation information collected through the in-vehicle wireless device 2. . The registered user information DB 542 stores the user information of each crew member and the group information 261 of the in-vehicle wireless device 2 that can be used by each crew member in association with each other.

  The control unit 55 is connected to the wireless communication unit 53, the operation unit 51, the call unit 52, and the storage unit 54. The control unit 55 is configured by a microcomputer or the like, and has a function of controlling each unit by developing a control program stored in a ROM (not shown) in a RAM (not shown).

  The control unit 55 functions as a vehicle operation management unit 551 that receives vehicle operation information from each in-vehicle wireless device 2 and analyzes and manages the vehicle operation information. Based on the vehicle operation information collected from the in-vehicle wireless device 2 and the information obtained by analyzing the vehicle operation information, the vehicle operation management unit 551 checks which vehicle is on which vehicle and the operation state of the vehicle. It can be stored in the operation information DB 541. In addition, the vehicle operation information collected from the in-vehicle wireless device 2 and information obtained by analyzing the vehicle operation information can be transmitted to each in-vehicle wireless device 2 to notify the crew through the operation terminal 3. In addition, the vehicle operation management unit 551 can add the crew member user information to the registered user information DB 542, and can change the group information 261 of the in-vehicle wireless device 2 that can be used by the crew member. The vehicle operation management unit 551 periodically transmits the group information 261 and the plurality of user information 262 stored in the registered user information DB 542 to each in-vehicle wireless device 2, and is mounted on the vehicle with the transmitted group information 261 and the plurality of user information 262. The group information 261 and the plurality of user information 262 stored in the authentication information storage unit 26 of the wireless device 2 can be updated.

  With reference to FIG. 8, the flow of processing in which the in-vehicle wireless device 2 causes the operation terminal 3 and the command station 5 to perform wireless communication will be described.

  The terminal connection unit 27 of the in-vehicle wireless device 2 determines whether the operation terminal 3 is connected (step s11). If not connected (No in step s11), the process returns to step s11. When the operation terminal 3 is connected (Yes in step s11), the terminal connection unit 27 determines whether it is a wireless LAN connection, that is, a wireless LAN connection or a wired connection (step s12).

  In the case of wireless LAN connection (Yes in step s12), the terminal connection unit 27 determines whether or not the received electric field strength of the received signal of the operation terminal 3 connected to the wireless LAN exceeds a predetermined threshold value 86 (step s13). . When the received electric field strength exceeds the predetermined threshold value 86 (Yes in Step s13), the terminal terminal 27 disconnects the wireless LAN connection with the operation terminal 3 because the operation terminal 3 is in the vehicle (Step s14). This process is terminated.

  On the other hand, if the received electric field strength does not exceed the predetermined threshold value 86 even when the wireless LAN connection is not established (No in step s12 and No in step s13), the communication control unit of the in-vehicle wireless device 2 23 acquires user information 311 from the operation terminal 3 connected to the terminal connection unit 27 (step s15), and whether or not the user can use the group of the in-vehicle wireless devices 2 via the authentication unit 25 Is determined (step s16).

  If the user is not a user who can use the group of the in-vehicle wireless devices 2 (No in step s16), the communication control unit 23 disallows wireless communication with the command station 5 by the operation terminal 3 (step s17). This process ends. The communication control unit 23 may disconnect the connection between the operation terminal 3 and the terminal connection unit 27 when wireless communication with the command station 5 is not permitted.

  On the other hand, when the user can use the group of the in-vehicle wireless devices 2 (Yes in step s16), the communication control unit 23 permits the wireless communication with the command station 5 by the operation terminal 3 (step s18). . Subsequently, the communication control unit 23 causes the operation terminal 3 to wirelessly communicate with the command station 5 in accordance with the wireless communication connection order of the operation terminal 3 (step s19), and ends this process.

  The communication control unit 23 is connected to the operation terminal 3 in the order in which wireless communication with the command station 5 is permitted or the connection to the terminal connection unit 27 among the operation terminals 3 connected to the terminal connection unit 27. A rank may be assigned. However, when there is the terminal connection unit 27 and the operation terminal 3 connected in a wired connection, the communication control unit 23 sets the wireless communication connection order of the operation terminal 3 connected in a wired manner to the highest and connects to another wireless LAN. The operating terminal 3 is controlled so as to be capable of wireless communication according to the availability of the wireless communication band with the command station 5.

  The wireless LAN connection control unit 272 of the terminal connection unit 27 monitors each operation terminal 3 that is connected to the wireless LAN. When the received electric field strength exceeds a predetermined threshold value 86, the operation terminal is in each case. 3 is transmitted so that the wireless LAN connection with the operation terminal 3 is disconnected.

  If the user information that matches the user information 311 of the operation terminal 3 is not stored in the authentication information storage unit 26, the authentication unit 25 stores the user information 311 of the operation terminal 3 in the registered user information DB 542 of the command station 5. You may make it authenticate by collating with the stored user information. In this case, the authentication unit 25 may acquire user information 262 associated with the group of the in-vehicle wireless device 2 from the command station 5 and use it for user authentication. Further, the authentication unit 25 may acquire the authentication result from the command station 5 by transmitting the user information 311 of the operation terminal 3 to the command station 5 so as to be authenticated inside the command station 5.

  As described above, the wireless communication device 1 of the present embodiment is configured so that the in-vehicle wireless device 2 and the operation terminal 3 can be separated wirelessly, and the in-vehicle wireless device 2 is wired to the operation terminal 3 in the vehicle, Since the terminal connection unit 27 for wireless LAN connection with the operation terminal 3 outside the vehicle is provided, the in-vehicle wireless device 2 and the operation terminal 3 can communicate by wireless LAN connection when the crew member takes the operation terminal 3 out of the vehicle. is there. The in-vehicle wireless device 2 mounted on each vehicle is group-registered and has a plurality of user information 262 registered in the group. The user information 311 is acquired from the connected operation terminal 3 and user information is acquired. The operation terminal 3 corresponding to the group is authenticated by checking 311 with a plurality of user information 262, and the operation of the operation terminal 3 that has succeeded in authentication is accepted. Therefore, the user of the vehicle-mounted wireless device 2 can be limited and security can be improved. Moreover, since a crew member can use the in-vehicle wireless device 2 of the same group, the boarding vehicle can be changed. The in-vehicle wireless device 2 determines whether the operation terminal 3 connected to the wireless LAN is in the vehicle or outside the vehicle based on the received electric field strength of the operation terminal 3 connected to the wireless LAN. Since the connection with the operation terminal 3 connected via the LAN is disconnected, it is possible to prevent the in-vehicle wireless device 2 from being operated wirelessly in the vehicle and to comply with the Road Traffic Law. Further, since the in-vehicle wireless device 2 can wirelessly communicate a plurality of operation terminals 3 connected to the terminal connection unit 27 with the command station 5, the higher the communication function of the in-vehicle wireless device 2 (there is a margin in the communication band). The operation terminal 3 of many group users can be wirelessly communicated with the command station 5.

As described above, the present invention is outlined.
(1) A wireless communication device of the present invention is a wireless communication device including an in-vehicle wireless device installed in a vehicle and an operation terminal of the in-vehicle wireless device, and the in-vehicle wireless device is the operation terminal in the vehicle. And a terminal connection unit for wireless LAN connection with the operation terminal outside the vehicle, and the in-vehicle wireless device and the operation terminal can be separated wirelessly.
(2) In addition, the in-vehicle wireless device has a group registered, and has user information corresponding to the group, and the user information stored in the connected operation terminal corresponds to the user information corresponding to the group An authentication unit that authenticates whether or not, and a communication control unit that enables wireless communication between the command terminal and one or more operation terminals that store user information corresponding to the group.
(3) In addition, the terminal connection unit determines whether the operation terminal connected to the wireless LAN is inside the vehicle or outside the vehicle based on the received electric field strength of the operation terminal connected to the wireless LAN. And a wireless LAN connection control unit that disconnects the wireless LAN connection with the operation terminal determined to be in the vehicle.
(4) When the terminal connection unit is connected to both the operation terminal in the vehicle and the operation terminal outside the vehicle, the operation terminal in the vehicle and the command station are preferentially wirelessly communicated, and the command The operation terminal outside the vehicle may wirelessly communicate with the command station in accordance with the availability of a wireless communication band with the station.
(5) The present invention is a wireless communication system including an in-vehicle wireless device installed in a vehicle and an operation terminal of the in-vehicle wireless device, and the in-vehicle wireless device is connected to the operation terminal in the vehicle by wire. A terminal connection unit for wireless LAN connection with the operation terminal outside the vehicle is provided, and the in-vehicle wireless device and the operation terminal are configured to be separable wirelessly.
(6) Moreover, the said vehicle-mounted radio | wireless machine may have a vehicle information analysis part which transmits the vehicle operation information of the said installed vehicle to a command station.
(7) The vehicle information analysis unit may automatically transmit vehicle operation information to the command station in the event of a disaster.

The present invention is not limited to the above-described embodiment, and it goes without saying that various changes can be made without departing from the spirit of the present invention.
For example, in the above-described embodiment, the case where the in-vehicle wireless device 2 includes the reception electric field strength determination unit 273 and the wireless LAN connection control unit 272 is taken as an example. However, the operation terminal 3 may have these functions. That is, the terminal control unit 36 of the operation terminal 3 measures the received electric field strength of the signal received from the in-vehicle wireless device 2 via the receiving unit of the wireless LAN connection 32, and the measured received electric field strength exceeds a predetermined threshold value. By determining whether or not the own operation terminal 3 is in the vehicle or outside the vehicle, it may be controlled to turn on / off communication with the in-vehicle wireless device 2 by the wireless LAN. That is, when the terminal control unit 36 determines that the terminal device 3 is in the vehicle, the terminal control unit 36 disconnects the wireless LAN connection with the in-vehicle wireless device. Also by this, the same effect as the above-described embodiment can be obtained.
Further, the operation terminal 3 may start communication with the in-vehicle wireless device 2 by the wireless LAN when the operator operates the operation unit 35, and the terminal control unit 36 is connected via the wired connection unit 33. When it is determined that the connection with the in-vehicle wireless device 2 has been disconnected, the connection processing by the wireless LAN connection unit 32 may be automatically started periodically. As a result, the crew can automatically connect to the in-vehicle wireless device 3 by wireless LAN by simply removing the wired connection of the operation terminal 3 and taking it out of the vehicle, and wireless communication using the operation terminal 3 can be performed. Will improve. When the terminal control unit 36 determines that the wired connection has been disconnected without automatic connection, a display prompting the start of the wireless LAN connection on the display unit (not shown) of the operation terminal 3, for example, whether to make a wireless LAN connection or not. The selection screen may be displayed. Thereby, since a crew member only removes the operation terminal 3 from the vehicle-mounted radio | wireless machine 2, since a wireless LAN connection screen is displayed on a display part, the convenience improves.
Furthermore, in the above-described embodiment, the case where the connection destination by the wireless LAN connection unit 32 of the operation terminal 3 is the in-vehicle wireless device 2 has been described as an example. However, the present invention is not limited to this, and the operation terminal 3 may be connectable to a wireless LAN connection point other than the in-vehicle wireless device 2.
