Description

Technical Field

[0001] The present invention relates to a short-distance wireless communication system for connecting a mobile communication terminal and a vehicle-mounted communication terminal through short-distance wireless communication. Background Art

[0002] As IoT devices develop, there are many wireless communication devices in construction sites. Many of these devices use short-range wireless communication that can be used without a protocol and share the communication band, which may cause communication performance to deteriorate due to mutual radio wave interference.

[0003] On the other hand, engineering machinery is required to realize body diagnostic functions by connecting mobile communication terminals such as smartphones to the body through short-range wireless communication, but the influence caused by radio wave interference on existing equipment needs to be suppressed to a minimum. On this basis, it is sometimes required to limit the communication band of short-range wireless functions according to the communication regulations in each country, or to prohibit the use of short-range wireless communication itself according to the situation. In view of this background, a method is required that can confirm the guidelines of laws and regulations while arbitrarily switching the action state of short-range wireless communication on the body side using wireless.

[0004] As a technology related to wireless switching, for example, a vehicle electronic key can be cited. According to Patent Document 1, the following function is realized: when the electronic key receives a start signal from the vehicle body, the electronic key ID information is sent to the vehicle body, and if the ID information is correct, the vehicle body unlocks the key.

[0005] In addition, when short-range wireless communication is enabled for use (turned on), guidelines for the laws and regulations of each country are required. In this case, a method is proposed in Patent Document 2, which compares communication restriction data (a data map divided into areas where wireless communication is allowed and areas where wireless communication is not allowed) with the current position of the vehicle body, and allows wireless communication when the vehicle body is located in an area without communication restrictions, and prohibits wireless communication when the vehicle body is located in an area with communication restrictions.

[0007] Patent Literature

[0008] Patent Document 1: Japanese Patent No. 5365979

[0009] Patent Document 2: Japanese Patent Application Publication No. 2008-121203 Summary of the invention

[0010] The technology of Patent Document 1 realizes a function of unlocking the vehicle by a key through communication between the vehicle body and the electronic key that are paired in advance, but does not take into account laws and regulations, and thus has the possibility of using short-range wireless communication in areas where communication is restricted.

[0011] Furthermore, the method of Patent Document 2 requires storing the communication restriction data on the vehicle body side. Therefore, if the communication restriction data is not updated to the latest information, wireless communication may be erroneously permitted in the area where the communication restriction has been newly introduced.

[0012] The present invention has been made in view of the above problems, and an object of the present invention is to provide a short-range wireless communication system capable of connecting a mobile communication terminal and an in-vehicle communication terminal through short-range wireless communication while complying with the latest laws and regulations.

[0013] In order to achieve the above-mentioned object, the short-distance wireless communication system of the present invention comprises: an on-vehicle communication terminal mounted on a vehicle body; and a mobile communication terminal that can be connected to the on-vehicle communication terminal via a short-distance wireless communication line, wherein the short-distance wireless communication system comprises a management server connected to the on-vehicle communication terminal and the mobile communication terminal via a communication network, and when the mobile communication terminal is connected to the on-vehicle communication terminal via the short-distance wireless communication line, the management server transmits a wireless communication activation request to the management server, and the management server is configured to have a storage unit that obtains and stores the latest legal and regulatory information, and when receiving the wireless communication activation request from the mobile communication terminal, based on the latest legal and regulatory information stored in the storage unit, determines whether the current position of the vehicle body received from the on-vehicle communication terminal is included in an area where short-distance wireless communication is allowed, and when it is determined that the current position is included in the area where short-distance wireless communication is allowed, the wireless communication activation request is transmitted to the on-vehicle communication terminal, and when it is determined that the current position is not included in the area where short-distance wireless communication is allowed, the wireless communication activation request is not transmitted to the on-vehicle communication terminal.

[0014] According to the present invention constructed as described above, only when the management server determines that the vehicle body is in an area where short-range wireless communication is permitted, the wireless communication start request sent by the mobile communication terminal is received by the vehicle-mounted communication terminal via the management server. Thus, the mobile communication terminal and the vehicle-mounted communication terminal can be connected through short-range wireless communication while complying with the latest laws and regulations.

[0015] Effects of the Invention

[0016] According to the short-distance wireless communication system of the present invention, it is possible to connect a mobile communication terminal and a vehicle-mounted communication terminal through short-distance wireless communication in accordance with the latest laws and regulations.

[0021] Hereinafter, the embodiments of the present invention will be described using the drawings. In the drawings, the same reference numerals are given to the same elements, and duplicate descriptions are omitted as appropriate.

[0022] Example 1

[0023] Figure 1 1 is a diagram showing a configuration of a short-distance wireless communication system in a first embodiment of the present invention. The short-distance wireless communication system in the first embodiment includes a mobile communication terminal 1 , an in-vehicle communication terminal 2 , and a management server 3 .

[0024] The mobile communication terminal 1 is composed of, for example, a smart phone or a tablet computer carried by an operator 4, and can communicate with the vehicle-mounted communication terminal 2 via short-range wireless communication, and can communicate with the management server 3 via a communication network 5 mainly composed of a cellular communication line and the Internet. The vehicle-mounted communication terminal 2 is mounted on the vehicle body 6, and is connected to the in-vehicle network (not shown) mainly through a wired connection, and is connected to the vehicle body system 7 via the in-vehicle network. The vehicle-mounted communication terminal 2 can communicate with the management server 3 via the communication network 5. Figure 1 In the drawings, a hydraulic excavator is exemplified as the vehicle body 6 , but the type of the vehicle body 6 is not particularly limited.

[0025] When the vehicle body 6 is in normal operation, the short-range wireless communication of the vehicle-mounted communication terminal 2 is turned off (invalid). When the mobile communication terminal 1 is connected to the vehicle-mounted communication terminal 2 via the short-range wireless communication, it sends a wireless communication start request to the management server 3 via the communication network 5. The management server 3 determines whether there is no problem even if the wireless communication start request is sent to the vehicle-mounted communication terminal 2 based on the position information of the vehicle body 6, etc. The vehicle-mounted communication terminal 2 that receives the wireless communication start request sets the short-range wireless communication to be turned on (valid), and sends the information (connection information) necessary for the communication connection with the vehicle-mounted communication terminal 2 to the mobile communication terminal 1 via the management server 3. The mobile communication terminal 1 is connected to the vehicle-mounted communication terminal 2 via the short-range wireless communication, and receives monitoring data from the vehicle body 6. The operator 4 uses the monitoring data received from the vehicle body 6 as a reference to perform maintenance work, etc. The mobile communication terminal 1 can also set parameters and operate the vehicle-mounted communication terminal 2 and the vehicle body system 7. Since the mobile communication terminal 1 is wirelessly connected to the vehicle-mounted communication terminal 2, a wired connection to the communication port in the cabin is not required, and the operator 4 can work without worrying about connection even when outside the cabin such as the engine room.

[0026] Figure 2 The management server 3 has: a storage unit 17 for acquiring and storing the latest legal and regulatory information; a permitted area determination unit 8 for determining the area (operating area) where the vehicle body 6 is operating based on the current position of the vehicle body 6 received from the vehicle-mounted communication terminal 2; a wireless communication permission determination unit 9 for receiving a wireless communication activation request from the mobile communication terminal 1 and comparing the operating area with a communication permission country list prepared based on the latest laws and regulations of each country to determine whether communication is possible; a wireless communication activation request transmission unit 10 for transmitting the wireless communication activation request to the vehicle-mounted communication terminal 2; and a connection information transmission unit 11 for transmitting connection information to the mobile communication terminal 1.

[0027] In addition to the vehicle communication terminal 2, the vehicle body 6 is equipped with a vehicle monitor 12, a monitor controller 13 for controlling the vehicle monitor 12, and a user interface 14 capable of inputting instructions to the monitor controller 13 according to the operation of the operator 4. The functions of these devices will be described later. In addition, the maintenance tool 15 and the management server operation terminal 16 will be described through the following embodiments.

[0028] Figure 3 1 is a flowchart showing the processing of the short-range wireless communication system.

[0029] First, the operator 4 inputs information that can identify the vehicle body 6 to be connected by short-range wireless communication to the mobile communication terminal 1, and sends a wireless communication start request to the management server 3 via the communication network 5 (step S101). At this time, the information inherent to the mobile communication terminal 1 (such as the MAC address) may also be sent together.

[0030] The management server 3 determines whether a wireless communication start request is received from the mobile communication terminal 1 (step S102). If a wireless communication start request is received, a location request is sent to the vehicle-mounted communication terminal 2 via the communication network 5 (step S103). The vehicle-mounted communication terminal 2 that receives the location request sends the current location of the vehicle body 6 to the management server 3 (step S104).

[0031] The management server 3 that has acquired the current position of the vehicle body 6 determines whether the vehicle body 6 is in an area where short-range wireless communication is permitted (whether wireless communication is permitted or not) (step S105). Alternatively, instead of step S103, the current position of the vehicle body 6 may be inquired from the communication carrier currently being used by the vehicle-mounted communication terminal 2, or the current position of the vehicle body 6 may be estimated based on the customer information logged in to the management server 3.

[0032] The management server 3 that determines that short-range wireless communication is possible sends a wireless communication start request to the vehicle-mounted communication terminal 2 (step S106). Here, when the information inherent to the mobile communication terminal 1 is acquired, it can also be sent to the vehicle-mounted communication terminal 2. In this way, communication connection can be allowed only for a specific mobile communication terminal 1 that has requested a communication connection.

[0033] The management server 3 that determines that short-distance wireless communication is not possible notifies the mobile communication terminal 1 that short-distance wireless communication is not permitted (step S107). The mobile communication terminal 1 that is notified that short-distance wireless communication is not permitted displays that short-distance wireless communication is not available on the terminal screen and notifies the operator 4 (step S108).

[0034] The vehicle-mounted communication terminal 2 determines whether a wireless communication activation request is received from the management server 3 (step S109). If a wireless communication activation request is received, the short-range wireless communication is turned on (valid) (step S110), and the connection information is sent to the management server 3 (step S111). The connection information referred to here is, for example, an ID and a password.

[0035] The management server 3 that receives the connection information from the vehicle-mounted communication terminal 2 sends the connection information to the mobile communication terminal 1 (step S112). The mobile communication terminal 1 that receives the connection information connects to the vehicle-mounted communication terminal 2 using short-range wireless communication (step S113). When the vehicle-mounted communication terminal 2 receives the inherent information of the mobile communication terminal 1 from the management server 3, it compares it with the inherent information of the mobile communication terminal 1 that has attempted to connect, and allows the connection only when the two are consistent.

[0036] In addition, in order to prevent interference with military lines and weather satellites, some countries sometimes prohibit the use of part of the short-range wireless communication band. In addition, in other countries, there is a demand to use as many bands as possible for communication, based on the fact that the more bands that can be used, the higher the communication performance. Therefore, the structure that allows / prohibits the use of short-range wireless communication itself can be replaced with a structure that allows / prohibits the use of a specific band, for example.

[0037] In addition, it is considered that when the vehicle body 6 is operated near the border, the operating area may be wrongly determined based on the information of the satellite positioning system such as GPS. Therefore, it can also be configured so that when the vehicle body 6 is operated within a fixed distance from the border, a screen is displayed on the vehicle monitor 12 to inquire whether the operating area determined by the management server 3 is correct, and when the operator 4 confirms that it is correct, the wireless communication is switched to on, and when it is not confirmed that it is correct, the actual operating area is sent to the management server 3, so that the management server 3 determines that wireless communication is possible within the operating area. Alternatively, it can also be configured so that the short-range wireless communication is not turned on when the vehicle body 6 is operated within a fixed distance from the border.

[0038] In addition, there is sometimes a requirement to turn on short-range wireless communication only when it is needed, so a configuration in which the short-range wireless communication is turned off after the communication is disconnected is also considered. However, in this configuration, it takes time to reconnect each time after disconnection depending on the radio wave conditions, so the convenience of using the short-range wireless communication function is reduced. Therefore, it is also possible to configure, for example, to keep the wireless communication turned on for a sufficient time to use the short-range wireless communication function during the period when the key switch of the vehicle body 6 is turned on and until the date changes. In addition, considering the risk of crossing the national border with the short-range wireless communication turned on, it is also possible to switch the short-range wireless communication to off after moving a fixed distance.

[0039] In the first embodiment, a short-distance wireless communication system includes: an on-vehicle communication terminal 2 mounted on a vehicle body 6; and a mobile communication terminal 1 that can be connected to the on-vehicle communication terminal 2 via a short-distance wireless communication line, wherein the short-distance wireless communication system includes a management server 3 connected to the on-vehicle communication terminal 2 and the mobile communication terminal 1 via a communication network 5, and when the mobile communication terminal 1 is connected to the on-vehicle communication terminal 2 via the short-distance wireless communication line, the management server 3 sends a wireless communication activation request to the management server 3, and the management server 3 is configured to have a storage unit 17 that obtains and stores the latest legal and regulatory information, and when receiving the wireless communication activation request from the mobile communication terminal 1, based on the latest legal and regulatory information stored in the storage unit 17, determines whether the current position of the vehicle body 6 received from the on-vehicle communication terminal 2 is included in an area where short-distance wireless communication is allowed, and when it is determined that the current position is included in the area where short-distance wireless communication is allowed, the wireless communication activation request is sent to the on-vehicle communication terminal 2, and when it is determined that the current position is not included in the area where short-distance wireless communication is allowed, the wireless communication activation request is not sent to the on-vehicle communication terminal 2.

[0040] According to the first embodiment constructed as described above, only when the management server 3 determines that the vehicle body 6 is present in an area where short-range wireless communication is permitted, the wireless communication start request sent by the mobile communication terminal 1 is received by the vehicle-mounted communication terminal 2 via the management server 3. Thus, the mobile communication terminal 1 and the vehicle-mounted communication terminal 2 can be connected by short-range wireless communication in accordance with the latest laws and regulations.

[0041] In addition, the vehicle-mounted communication terminal 2 in the first embodiment turns off the short-distance wireless communication when the short-distance wireless communication is turned on and moves a fixed distance, or when a fixed time has passed after the short-distance wireless communication is turned on. This can improve the convenience of the short-distance wireless communication and prevent the vehicle body 6 from intruding into an area where the short-distance wireless communication is not allowed when the short-distance wireless communication is turned on.

[0042] Example 2

[0043] The second embodiment of the present invention will be described with the differences from the first embodiment as the center. In the first embodiment, when determining whether short-range wireless communication is possible, a location request is sent from the management server 3 to the vehicle-mounted communication terminal 2, and the vehicle-mounted communication terminal 2 that receives the location request sends the current location of the vehicle body 6 to the management server 3. Therefore, the processing time until the short-range wireless communication is turned on and the communication cost in the communication network 5 increase. The second embodiment takes this into consideration.

[0044] The vehicle-mounted communication terminal 2 periodically transmits the position information of the vehicle body 6 to the management server 3. In the second embodiment, the position information transmitted periodically is used to assist in determining whether wireless communication is possible. Figure 4 Describe the sequence.

[0045] Figure 4 1 is a flowchart showing the processing of the short-distance wireless communication system in the second embodiment. Each step will be described below in sequence.

[0046] First, the operator 4 inputs information that can identify the vehicle body 6 to be connected by short-range wireless communication into the mobile communication terminal 1, and transmits a wireless communication start request to the management server 3 via the communication network 5 (step S201).

[0047] The management server 3 determines whether a wireless communication start request is received from the mobile communication terminal 1 (step S202). If a wireless communication start request is received, it determines whether wireless communication is possible at the position (past position) indicated by the position information last received from the vehicle-mounted communication terminal 2 (step S203). If it is determined that wireless communication is possible, a conditional wireless communication start request and the past position are sent to the vehicle-mounted communication terminal 2 (step S204). If it is determined that wireless communication is not possible, a position request is sent to the vehicle-mounted communication terminal 2 (step S205). This process is similar to the process described above. Figure 3 The same as step S103.

[0048] The vehicle-mounted communication terminal 2 determines whether a conditional wireless communication activation request is received from the management server 3 (step S206). The vehicle-mounted communication terminal 2 that receives the conditional wireless communication activation request determines whether the moving distance from the past position received from the management server 3 to the present position is below a predetermined threshold value (step S207). If it is below the predetermined threshold value, the short-range wireless communication is set to be activated (step S208). The threshold value referred to here is set to, for example, a distance that can be regarded as the vehicle body 6 not moving within the operating site from the past position. The subsequent processing of step S208 is the same as that of step S208. Figure 3 The processing after step S111 shown is the same.

[0049] If the moving distance from the past position to the present position is greater than the threshold, it is assumed that the vehicle body 6 is moving to another site or being transported abroad, and thus the present position is sent to the management server 3 (step S209), and the determination of whether wireless communication is possible is performed again. Figure 3 The processing after step S105 shown is the same.

[0050] The vehicle-mounted communication terminal 2 in the second embodiment periodically sends the position information of the vehicle body 6 to the management server 3. When the management server 3 receives the wireless communication start-up request from the mobile communication terminal 1 and when the position information of the vehicle body 6 last received from the vehicle-mounted communication terminal 2, i.e., the past position information, is included in the area where short-range wireless communication is allowed, the vehicle-mounted communication terminal 2 sends the past position information to the vehicle-mounted communication terminal 2. When the moving distance from the past position information to the current position information of the vehicle body 6 is less than a specified threshold, the vehicle-mounted communication terminal 2 starts short-range wireless communication. When the moving distance is greater than the threshold, the short-range wireless communication is not started and the current position information is sent to the management server 3.

[0051] According to the second embodiment configured as described above, only when the vehicle body 6 is operating near a past location (the same country, the same site, etc.) where short-range wireless communication is permitted, the transmission of the location request from the management server 3 to the vehicle-mounted communication terminal 2 and the transmission of the location information from the vehicle-mounted communication terminal 2 to the management server 3 are omitted. As a result, the processing time until the short-range wireless communication is turned on and the communication cost in the communication network 5 can be suppressed.

[0052] Example 3

[0053] The third embodiment of the present invention is described with the differences from the first embodiment as the center. In the configuration of the first embodiment, the short-range wireless communication is set to be valid (on) via the communication network 5. However, depending on physical conditions such as the operating state of the vehicle body 6, there is a situation where the communication between the mobile communication terminal 1 or the vehicle-mounted communication terminal 2 and the communication network 5 cannot be achieved (the connection with the base station cannot be established). In this case, the short-range wireless communication cannot be set to be valid (on). Therefore, a feedback method for manually setting the short-range wireless communication to be valid (on) is required. The third embodiment takes this requirement into consideration.

[0054] The monitor controller 13 in the third embodiment can display an operation menu of "manual wireless communication start" on the vehicle monitor 12 according to the operation performed by the operator 4 on the vehicle monitor 12. When the operator 4 selects the operation menu, the vehicle communication terminal 2 sets the short-range wireless communication to start, and displays the connection information on the vehicle monitor 12. The connection information in this case is displayed by, for example, an image code (barcode and QR code) that can be read by the camera of the mobile communication terminal 1.

[0055] In the third embodiment where wireless communication can be manually activated, the operator 4 needs to obtain the latest communication restriction status from the management server 3 in advance and be careful not to activate short-range wireless communication in a communication-prohibited country. Since it is necessary to confirm afterwards whether the manual activation of wireless communication is in accordance with the latest laws and regulations, the vehicle-mounted communication terminal 2 may record the location information of activating the wireless communication when it is manually activated, and notify the management server 3 after the communication network 5 can be used.

[0056] In addition, it can also be configured that when the vehicle-mounted communication terminal 2 detects that the communication network 5 cannot be used (for example, outside the communication circle), the monitor controller 13 displays an operation menu of "manual wireless communication activation" on the vehicle-mounted monitor 12, and makes the operation menu disappear after the communication network 5 can be used again.

[0057] The short-distance wireless communication system in the third embodiment includes an on-vehicle monitor 12 mounted on the vehicle body 6. When the on-vehicle communication terminal 2 detects that the communication network 5 is unavailable, the on-vehicle monitor 12 displays an operation menu for manually starting the short-distance wireless communication.

[0058] According to the third embodiment configured as described above, when the in-vehicle communication terminal 2 cannot use the communication network 5, the operator 4 can quickly turn on the short-range wireless communication manually.

[0059] Example 4

[0060] The fourth embodiment of the present invention will be described with a focus on the differences from the third embodiment. In the third embodiment, the operator 4 can manually start wireless communication, which may result in the operator 4 not paying attention and using short-range wireless communication in violation of the latest laws and regulations. The fourth embodiment takes this into consideration.

[0061] The vehicle-mounted communication terminal 2 in the fourth embodiment has an operation mode that prohibits the operator 4 from manually turning on the wireless communication. That is, the vehicle-mounted communication terminal 2 has three operation modes, namely, a "wireless communication effective mode", a "wireless communication stop mode", and a "wireless communication prohibition mode", wherein the "wireless communication effective mode" is an operation mode in which the short-range wireless communication is set to be turned on (effective), the "wireless communication stop mode" is an operation mode in which the short-range wireless communication is set to be turned off (invalid) and can be set to be turned on (effective) by a wireless communication turn-on request, and the "wireless communication prohibition mode" is an operation mode in which the short-range wireless communication is set to be turned off (invalid) and switching to on (effective) is not allowed.

[0062] The switching from the wireless communication stop mode to the wireless communication enable mode is the same as that described in the first embodiment. The switching from the wireless communication stop mode to the wireless communication disable mode is performed through the operation menu on the vehicle monitor 12, or from the mobile communication terminal 1 via the communication network 5. The switching from the wireless communication enable mode to the wireless communication disable mode is performed through the operation menu on the vehicle monitor 12, or from the mobile communication terminal 1 via the communication network 5 or short-range wireless communication. The switching from the wireless communication disable mode to the wireless communication stop or wireless communication enable is not allowed except for the initialization and design commands for factory settings.

[0063] Furthermore, when the vehicle-mounted communication terminal 2 receives a request to start wireless communication in the wireless communication prohibition mode, the vehicle-mounted communication terminal 2 may be notified to the mobile communication terminal 1 via the management server 3 that the short-range wireless communication cannot be started. Furthermore, when the management server 3 holds information that wireless communication is prohibited, the management server 3 that receives the request to start wireless communication from the mobile communication terminal 1 may notify the mobile communication terminal 1 that short-range wireless communication is not possible without determining whether wireless communication is possible. Furthermore, the management server 3 may hold information on whether short-range wireless communication of a specific vehicle body 6 is prohibited, and the information may be changed from the mobile communication terminal 1 of the owner and the service personnel.

[0064] The short-range wireless communication system in the fourth embodiment has a vehicle-mounted monitor 12 mounted on the vehicle body 6, and the vehicle-mounted communication terminal 2 has: a wireless communication effective mode in which short-range wireless communication is effective; a wireless communication stop mode in which short-range wireless communication is turned off and the short-range wireless communication can be switched to on; and a wireless communication prohibited mode in which short-range wireless communication is turned off and the short-range wireless communication cannot be switched to on, and the switching from the wireless communication effective mode or the wireless communication stop mode to the wireless communication prohibited mode can be performed by operating the mobile communication terminal or the vehicle-mounted monitor, and the switching from the wireless communication prohibited mode to the wireless communication effective mode or the wireless communication stop mode cannot be performed by operating the mobile communication terminal or the vehicle-mounted monitor.

[0065] According to the fourth embodiment constructed as described above, a wireless communication prohibited mode is provided in the vehicle-mounted communication terminal 2. By disabling the switching from the wireless communication prohibited mode to the wireless communication valid mode or the wireless communication stop mode based on the operation of the mobile communication terminal 1 or the vehicle-mounted monitor 12, it is possible to prevent the use of short-range wireless communication in violation of the latest laws and regulations due to the operator 4's inattention.

[0066] Example 5

[0067] The fifth embodiment of the present invention will be described with the focus on the differences from the first embodiment. There are cases where you want to disable short-range wireless communication even in an area where short-range wireless communication is permitted, for the reason that you absolutely do not want to interfere with IoT devices used for high-precision construction, etc. The fifth embodiment takes this into consideration.

[0068] The mobile communication terminal 1, the in-vehicle communication terminal 2, and the management server 3 in the fifth embodiment each store a signal (wireless communication use rejection signal) indicating whether or not to reject an attempt to use short-distance wireless communication.

[0069] The wireless communication use rejection signal of the mobile communication terminal 1 can be enabled by a predetermined operation on the mobile communication terminal 1. If an operation to send a wireless communication start request is performed when the wireless communication use rejection signal is enabled, the mobile communication terminal 1 notifies on the terminal screen that the wireless communication start request cannot be sent.

[0070] The wireless communication use rejection signal of the vehicle-mounted communication terminal 2 can be enabled by a predetermined operation on the vehicle-mounted monitor 12 or the maintenance tool 15. When the vehicle-mounted communication terminal 2 receives a wireless communication activation request in a state where the wireless communication use rejection signal is enabled, the vehicle-mounted communication terminal 2 does not activate the short-range wireless communication, and notifies the mobile communication terminal 1 through the management server 3 that the short-range wireless communication cannot be activated.

[0071] The wireless communication use rejection signal of the management server 3 can be enabled by a predetermined operation on the management server operation terminal 16 composed of a personal computer and a tablet computer. When the management server 3 receives a wireless communication start request in a state where the wireless communication use rejection signal is enabled, the management server 3 does not perform a wireless communication permission judgment, and notifies the mobile communication terminal 1 that the short-range wireless communication cannot be enabled.

[0072] The mobile communication terminal 1 in the fifth embodiment stores a first signal (wireless communication use rejection signal) that can be validated by a prescribed operation. When an operation to send the wireless communication start request is performed while the first signal is validated, the wireless communication start request is not sent to the management server 3, and a notification that the wireless communication start request cannot be sent is reported on the terminal screen. The vehicle-mounted communication terminal 2 stores a second signal (wireless communication use rejection signal) that can be validated by a prescribed operation on the vehicle-mounted monitor 12 or the maintenance tool 15. When a wireless communication start request is received from the management server 3 while the second signal is validated, the short-range wireless communication is not started, and a notification that the short-range wireless communication cannot be started is reported to the mobile communication terminal 1 via the management server 3. The management server 3 stores a third signal (wireless communication use rejection signal) that can be validated by a prescribed operation. When the wireless communication start request is received from the mobile communication terminal 1 while the third signal is validated, the wireless communication start request is not sent to the vehicle-mounted communication terminal 2, and a notification that the short-range wireless communication cannot be started is reported to the mobile communication terminal 1.

[0073] According to the fifth embodiment constructed as described above, by activating any one of the wireless communication use rejection signals stored in the mobile communication terminal 1, the vehicle-mounted communication terminal 2 and the management server 3, short-range wireless communication can be made unusable even in an area where short-range wireless communication is permitted.
