Currently, in home security services or devices provided on the market, as described in Non-Patent Document 1, those that can confirm the locked / unlocked state of locks such as windows and doors from a remote location. is there. In these cases, it is common to obtain an answer by inquiring about the lock state of the lock from a mobile phone or a computer to a server or the like that manages the lock state. At this time, in order to prevent confirmation by a third party other than the manager of the lock (usually a resident of the house where the lock is installed), the identity confirmation (authentication) of the lock manager is performed. This is usually by entering an ID and password.
On the other hand, a mobile phone or PHS (Personal Handyphone System) is added to the car's anti-theft device to provide a communication function, and in the event of an emergency, an alarm is sent to the car's owner, or vice versa. Then, there is a system that can perform function setting of the anti-theft device, ON / OFF of the system, and the like (for example, see Non-Patent Document 2). In addition, there is a system that can track the criminal and recapture the stolen vehicle in cooperation with the security company by tracking the location of the stolen car using positioning technology such as GPS (Global Positioning System). It has been put into practical use. These are becoming indispensable functions for car owners against the background of a significant increase in the number of car thefts in recent years.
Another point of view is that the above-mentioned vehicle location tracking function is useful for finding your own vehicle when the parking position is lost in a vast parking lot. Rather, it is widely used as a tool that makes car life more convenient.

  FIG. 1 is an overview of a key 100 according to the first embodiment of the present invention. The key 100 includes an insertion portion 110 that is inserted into a key hole of a lock 200 (not shown) and locked or unlocked, and a handle portion 120 that holds the key by hand when locking or unlocking. The handle unit 120 includes a display unit 121 that displays locking or unlocking information and the like, and an operation unit 122 that generates a trigger signal for the action when requesting the locking information. The display means 121 is realized by a flat display such as a liquid crystal display or an EL display (electroluminescence display). The operation means 122 is realized by a push button or the like. The external appearance of the key 100 differs greatly depending on the transmission / reception circuit, the display mounting method, the external appearance design, etc., and is not limited to that shown in FIG.

  FIG. 2 is a block diagram of the key 100. When the operation means 122 is operated (a button is pressed), the control means 123 transmits a key ID stored in the storage means 124 and an information request signal that is a signal for requesting information on the lock state of the lock. By driving 126, it is transmitted to the lock 200 (not shown). A signal transmitted from the lock 200 in response to this information request signal is received by the receiving means 127 and is displayed by the display means 121 through processing in the control means 123. The power supply to these is performed by the power supply means 125. As the power supply means 125, for example, a button-type battery is conceivable, but not limited thereto. Each means shown in FIG. 2 is built into the handle portion 120 of the key 100.

  FIG. 3 is a block diagram of a lock 200 (not shown). The key ID and the information request signal transmitted from the key 100 are received by the receiving unit 215. Thereafter, the control means identifies the key ID of the key 100 received together with the information request signal. If it matches the key ID stored in the storage means 212, the lock information (unlocked or locked) of the lock 200 at that time detected by the lock state detection means 213 is sent to the key 100 by the sending means 214. . If the key ID of the received key 100 does not match the key ID stored in the storage unit 212, only a message indicating that there is no information reception right is transmitted to the key 100, and the lock information of the lock 200 is not transmitted. As a power supply means, it is considered that there are few space restrictions compared to a key, so a large capacity battery can be used instead of a button type, but this is not restrictive.

  FIG. 4 is a flowchart for locking or unlocking. When the lock 200 is locked or unlocked using the key 100 (step S11, step S21), the lock 200 is detected to be locked or unlocked by the lock state detection means 213 (step S22). The determination result is “Yes”, and the process proceeds to step S24. If the lock state detection means 213 has not detected locking or unlocking, the determination result of step S23 is “No” and the process returns to step S22.

  In step S <b> 24, the lock 200 transmits a signal requesting transmission of the key ID to the key 100 by the transmitting unit 214. The key 100 receives the signal by the receiving means 127, and transmits the key ID stored in the storage means 124 to the lock 200 by the transmitting means 126 (step S12). When the lock 200 receives the key ID of the key 100 by the receiving means 215 (step S25), the lock 200 holds the key ID in the storage means 212 (step S26).

  FIG. 5 is a flowchart when the key 100 inquires the lock 200 of lock information. When the key 100 transmits the information request signal and the key ID by the transmitting means 126 (step S31), and the lock 200 receives the information request signal and the key ID by the receiving means 215 (step S41), the key 100 is received together with the information request signal. The key ID of the key 100 and the key ID stored in the storage means 212 are compared (step S42). If they match, the determination result in step S43 is “Yes” and the process proceeds to step S44. Send locking information as a message. On the other hand, if they do not match, the determination result in step S43 is “No”, the process proceeds to step S45, and a message “no information reception right” is transmitted to the key 100. The key 100 receives a message from the lock (step S32), and displays this message on the display means 121 (step S33).

  Although communication between the key 100 and the lock 200 is based on a wireless access method, when the key 100 and the lock 200 are greatly separated from each other, communication between the two is realized as shown in the schematic diagram of FIG. The present invention assumes that the public operator and the wide area operated by the telecommunications carrier so as not to impair the convenience of the user, that is, so that the locked state of the lock can be confirmed no matter where the user goes out. Via a wireless access network. For example, PHS network or NTT Docomo's DoPa network.

  According to this embodiment, the locked state of the lock is notified only to the owner of the key that locks or unlocks the lock. Normally, even if the resident changes due to moving, etc., the key itself is handed over to the next resident. In addition, since the locked state is displayed on the display incorporated in the key, the locked state is not notified to the previous resident. In addition, according to the present invention, even when there are a plurality of keys and only a part of them is taken over, the locked state is notified only to the key that has actually been locked or unlocked. The locked state is not notified. If there are multiple inhabitants and each owns a key, if the display says "No information reception right", at least you are not locked. If not, it is unlocked).

  The above effect is essentially due to the fact that the right authentication information (key ID) for knowing the lock and the lock information transmission / reception means and the display means are physically integrated with the key. is there. For example, when inquiring locking information with a mobile phone, even if it is not the owner of the key, it is possible to make an inquiry if only the authentication information is known.

  Next, a second embodiment will be described with reference to FIGS. FIG. 7 is a block diagram of the key 100 in the present embodiment. The difference from the first embodiment is that a key ID sending means 128 is provided separately. FIG. 8 is a block diagram of the corresponding lock 200. The difference from the first embodiment is that a key ID receiving means 217 is provided separately corresponding to the key ID sending means 128 in the key 100 of FIG. The key ID communication means and the lock information and request message communication means are separated because the key ID exchange performed between the key 100 and the lock 200 when the key 100 is locked or unlocked via the public network. This is because, by directly communicating, it is possible to avoid unauthorized acquisition of the key ID by interception or the like and to ensure safety. Therefore, the transmission and reception of the key ID of the present embodiment is performed at the time of locking or unlocking of the wireless narrow area communication such as DSRC (Dedicated Short Range Communication), or the locking between the key insertion part 110 and the keyhole part of the lock 200, for example. There is a method by wired communication using mechanical contact at the time of locking. The flow at the time of locking or unlocking and the flow in the case of inquiring about the lock information before lock are the same as those in FIGS. 4 and 5.

  Next, a third embodiment will be described with reference to FIGS. 9 and 10. In the present embodiment, the lock information is not requested from the key 100 to the lock 200. FIG. 9 is a block diagram of the key 100. Since the lock information is not requested, the operation unit 122 and the transmission unit 126 are not provided, and the key ID transmission unit 128 is provided, which is a difference from the first embodiment. FIG. 10 is a block diagram of the lock 200. Since the lock information request signal from the key 100 is not transmitted, the receiving unit 215 is not provided and the key ID receiving unit 217 is provided, which is a difference from the first embodiment.

  The flowchart when the lock 200 is locked or unlocked by the key 100 is the same as that shown in FIG. When locking or unlocking is performed, the key 100 transmits its key ID to the lock 200. The lock 200 receives and stores it.

  FIG. 11 is a flowchart of the lock side. The process in this flowchart is performed together with the process in the flowchart of FIG. 4 when the lock 200 is locked or unlocked by the key 100. When the lock 200 is locked or unlocked by the key 100, the determination result in step S51 is "Yes" and the process proceeds to step S52, and the key ID is received from the key 100 as shown in FIG. Step S52). On the other hand, when the action of locking or unlocking is not performed, the determination result of step S51 is “No”, and the process returns to step S51. After the process of step S52, the lock information is transmitted to the key 100 corresponding to the key ID received in step S52, and is stored in the storage unit 212 of the lock 200, ie, the lock key that is not locked or unlocked. A message “no reception right” is transmitted to the key 100 corresponding to the key ID other than the key ID received in step S52 (step S53). Every time a locking or unlocking action occurs, a message (locking information or “no reception right”) is transmitted to the key 100. Therefore, even if there is no information request from the key 100, the key 100 has a lock 200 at that time. Will be notified. When the process of step S53 ends, the process returns to step S51, and the above process is repeated.

  When the lock 200 receives the information request signal from the key 100 in the first embodiment and the second embodiment, and when the lock 200 is locked or unlocked in the third embodiment, the lock 200 is the key. Receive ID. At this time, after notifying the key 100 corresponding to the key ID held before reception of the change in the lock state accompanying locking or unlocking, the key ID is erased and locked or unlocked instead. It is also possible to hold the key ID of the key that has been performed. By doing so, it is possible to reduce the number of times the “no reception right” message is received when there are a plurality of key owners. However, this increases the risk that the lock state will be notified to a person who does not have the right to receive such as the previous owner. Which is implemented depends on the risk management policy settings.

Next, a fourth embodiment will be described. The difference from the third embodiment is that the lock 200 holds the key ID of the key 100 previously locked or unlocked within a certain period in addition to the last held key ID. The key lock state is transmitted to the key 100 corresponding to the key ID.
According to this embodiment, when there are a plurality of lock users (for example, when each couple has a key), the lock state can be transmitted to each.

  FIG. 12 is a flowchart on the lock side in this embodiment. The difference from FIG. 11 is that not only the key ID of the key 100 that was most recently locked or unlocked, but also the key ID of the key that was previously locked or unlocked must have passed for a certain period of time since it was locked or unlocked. For example, it is held at the lock 200 and the lock state is transmitted to the keys 100 corresponding to all the held key IDs.

That is, if there is a key ID held by the lock 200, the determination result in step S61 is “Yes” and the process proceeds to step S62. If there is no key ID held, the determination result is “No” and the process proceeds to step S65.
If the key ID held by the lock 200 in step S62 is the last stored key ID, the determination result is “Yes” and the process proceeds to step S65. If the key ID is not stored last, the determination result is “No” and step S63. Proceed to
In step S63, after the lock 200 has stored the key ID, if a certain period of time has elapsed, the determination result is “Yes”, the process proceeds to step S64, and the key ID is discarded. If the predetermined period has not elapsed, the determination result is “No”, and the process proceeds to step S65.
Step S65 and step S66 are the same as step S51 and step S52 in FIG. 11, except that if the determination result in step S65 is “No”, the process returns to step S61. After the process of step S66, in step S67, the lock state is transmitted to the keys 100 corresponding to all the key IDs held by the lock 200 as described above. After this process is completed, the process returns to step S61 and the above process is repeated.

  In general, a key user can assume that the frequency of locking / unlocking is not so small. This embodiment is based on the assumption, and if a certain period is set shorter than the period after the previous key user stops using, for example, longer than the interval used by the current key user, the lock 200 In this storage means, only the ID of the key owned by the current user is held, and it becomes possible to notify the lock state to all the current users.

Next, a fifth embodiment will be described.
FIG. 13 is a schematic diagram showing the overall configuration of a vehicle remote monitoring control system according to the fifth embodiment of the present invention. In the figure, a vehicle 1200 is a moving body and includes an in-vehicle unit 1210. The key 1100 of the vehicle 1200 and the in-vehicle unit 1210 perform wireless communication with the base station 1310 constituting the public wide area wireless access network 1300, respectively. Because of the nature of the remote monitoring / control function, the public wide area wireless access network 1300 used for communication between the key 1100 and the in-vehicle unit 1210 is preferably a public wide area wireless access network operated by a communication carrier. Examples thereof include a PHS (Personal Handyphone System) network and a DoPa (registered trademark) network which is a packet-based data communication service provided by NTT Docomo (registered trademark). Note that, for example, in the case of a DoPa (registered trademark) network, the service specifications are such that wireless terminals cannot directly communicate with each other. In that case, a relay server may be installed on the network.

When a remote monitoring control system as shown in FIG. 13 is operated, the number of mobile phones 1200 (locks) having a communication function (wireless function) and the number of keys 1100 is approximately the same as the population (below the population). Much more. Therefore, the public wide area wireless access network 1300 in FIG. 13 needs to be able to accommodate terminals several to several hundred times the population.
Unlike a wired network, in order to accommodate a large number of terminals in a wireless network having a large band resource limit, it is important how efficiently communication traffic can be accommodated. For example, the destination terminal ID field in the header can be omitted by fixing the communication partner. Further, in the case of communication between objects as in the present invention, there is a feature that the main information traffic is small and the ratio of control information traffic is relatively large compared to communication between persons. By utilizing this feature and optimizing the band allocation unit in the wireless MAC (Media Access Control) layer, the frame utilization efficiency can be improved. The above are features that are not found in conventional mobile phone networks and PHS networks.
However, the public wireless network can be applied to a mobile phone network and a PHS network as long as the number of terminals can be accommodated.
In addition, this type of remote monitoring and control system with communication functions incorporates a mechanism to protect against security threats such as eavesdropping and spoofing by malicious third parties by mutual authentication and encryption. It is common that Also in the present embodiment, it is desirable to provide these security functions for communication between the key 1100 and the in-vehicle unit 1210.

  FIG. 14 is an overview of the vehicle key 1100 shown in FIG. The key 1100 includes an insertion portion 1110 that is inserted into a keyhole of a door lock of the vehicle 1200 and locked or unlocked, and a handle portion 1120 that holds a key by hand when locking or unlocking. The handle 1120 includes a display unit 1121 for displaying various information and the like, and an operation unit 1122 for requesting locking information and the like and selecting / transmitting a vehicle control command. The display unit 1121 is realized by a flat display such as a liquid crystal display or an EL display. The operation means 1122 is realized by a push button or the like. The appearance of the key 1100 varies greatly depending on the transmission / reception circuit, the mounting method of the display, the appearance design, etc., and is not limited to FIG.

  FIG. 15 is a block diagram of the key 1100 shown in FIG. Using the operating means 1122 (button) and display means 1121 of the key 1100, the user selects various information requests or various control commands relating to the vehicle described below according to the situation. These selected various information requests or various control commands are transmitted to the in-vehicle unit 1210 of the vehicle 1200 via the transmission means 1126. The transmission information includes unique information for identifying the key itself, such as a key ID stored in the storage unit 1124 or a communication address of the key.

  Information returned from the in-vehicle unit 1210 according to the content of the transmission information received from the key 1100 is received by the receiving unit 1127, and is displayed by the display unit 1121 through processing in the control unit 1123. Each unit shown in FIG. 15 is built in the handle 1120 of the key 1100, and the power supply unit 1125 supplies power to each unit. As the power supply unit 1125, for example, a button-type battery can be considered, but this is not restrictive.

  FIG. 16 is a block diagram of the in-vehicle unit 1210 shown in FIG. Information transmitted from the key 1100 is received by the receiving means 1218. The control unit 1211 controls each unit and identifies the key ID or transmission address of the key 1100 included in the received information. If it matches the one stored in the storage unit 1212, the received information is Recognize that the information is correct.

  The in-vehicle unit 1210 includes position information acquisition means 1213. For the position information acquisition unit 1213, for example, GPS (Global Positioning System) is used. When a signal requesting vehicle position information is received from the key 1100, the position information acquired by the position information acquisition unit 1213 is transmitted to the key 1100 by the transmission unit 1217.

  Further, the in-vehicle unit 1210 includes a door lock monitoring control unit 1214. The door lock monitoring control unit 1214 is connected to the door lock system of the vehicle 1200, and can acquire the lock state and control the lock state based on the lock and unlock commands. When a signal requesting the door lock locked state of the vehicle is received from the key 1100, the lock state information acquired by the door lock monitoring control unit 1214 is transmitted to the key 1100 by the transmitting unit 1217. When a command for locking or unlocking the vehicle door lock is received from the key 1100, the door lock is locked or unlocked via the door lock monitoring control means 1214.

  Furthermore, the in-vehicle unit 1210 includes in-vehicle air conditioning monitoring control means 1215. The in-vehicle air conditioning monitoring control means 1215 is connected to the in-vehicle air conditioning system of the vehicle 1200 and can acquire in-vehicle temperature information and control the air conditioning system (ON / OFF of the air conditioner, etc.). When a signal requesting the temperature in the vehicle cabin is received from the key 1100, the temperature information in the vehicle cabin is acquired by the vehicle air conditioning monitoring control means 1215 and transmitted to the key 1100 by the transmission means 1217. Further, when a control command for the vehicle air conditioning system (ON / OFF of the air conditioning system, change of set temperature, etc.) is received from the key 1100, the vehicle air conditioning system is controlled via the vehicle air conditioning monitoring control means 1215.

  The in-vehicle unit 1210 includes power supply means 1216. A form of receiving power supply from the battery of the vehicle 1200 is common, but this is not a limitation.

  FIG. 17 is a flowchart relating to the remote monitoring of the position information of the vehicle 1200 in the remote monitoring control system for the vehicle shown in FIG. In the figure, the user selects a monitoring target, here, position information by using the button (operation unit 1122) of the key 1100 and the display (display unit 1121) (step S2010). Thereby, the position information transmission request is transmitted from the transmission means 1126 of the key 1100 to the in-vehicle unit 1210 of the vehicle 1200 (step S2020). When the receiving unit 1218 of the in-vehicle unit 1210 receives the position information transmission request, the position information acquiring unit 1213 acquires the position information (step S2030). The transmission unit 1217 transmits the position information acquired by the position information acquisition unit 1213 to the key 1100 (step S2040). The display (display unit 1121) of the key 1100 displays the position information received by the receiving unit 1127 (step S2050).

  FIG. 18 is a flowchart relating to remote control of the door lock in the vehicle remote monitoring control system shown in FIG. In the figure, the user selects a control command for instructing execution, here, door lock locking (step S2110) using the button (operation unit 1122) of the key 1100 and the display (display unit 1121). Thereby, the door lock locking request is transmitted from the transmitting means 1126 of the key 1100 to the in-vehicle unit 1210 of the vehicle 1200 (step S2120). When the receiving unit 1218 of the in-vehicle unit 1210 receives the door lock locking request, the door lock monitoring control unit 1214 transmits the door lock locking request to the door lock system of the vehicle 1200 (step S2130). When the door lock system locks the door of the vehicle 1200 (step S2140), the door lock system returns a door lock lock confirmation to the in-vehicle unit 1210 (step S2150). When the door lock monitoring control unit 1214 of the in-vehicle unit 1210 receives the door lock locking confirmation, the transmission unit 1217 transmits the door lock locking confirmation to the key 1100 (step S2160). When the reception unit 1127 of the key 1100 receives the door lock locking confirmation, the display (display unit 1121) displays the completion of the door lock locking (step S2170).

“Door lock locking request” can be read as “Door lock unlocking request” or “Door lock locking status request”, and “Door lock locking confirmation” can be read as “Door lock unlocking confirmation” or “Door lock locking status information”. For example, the door lock locking control and the remote monitoring of the locked state can be performed by the same flow as in FIG.
Further, when performing remote control or remote monitoring of the in-vehicle air conditioning system, “door lock system” in the flowchart shown in FIG. 18 may be read as “air conditioning system”.

  In the above description, position information and temperature are described as vehicles to be monitored. However, information obtained by, for example, a humidity sensor, a human condition sensor, a light / dark sensor, etc. can be considered depending on market needs. Obviously, these are within the scope of the present invention.

  Next, a vehicle remote monitoring control system according to a sixth embodiment will be described. The difference between this embodiment and the fifth embodiment is whether the vehicle key has a function of communicating with a remote vehicle or a monitoring control server (fifth embodiment) or not (this first) 6 embodiment). In this embodiment, a vehicle owner's portable information communication terminal (for example, a mobile phone) is used as a vehicle key communication function and information display function.

  An object of the present embodiment is to provide a method for more safely communicating vehicle information and vehicle control information with the vehicle owner at a remote location. In the fifth embodiment, the fact that “the vehicle key is owned” is applied as the fact that best represents the vehicle owner, and the vehicle key itself is given the right to monitor and control the vehicle. Has achieved this goal. On the other hand, in the present embodiment, by providing a random number generation function having the same algorithm in the key and the monitoring control server, authentication of the vehicle owner is performed when the two random numbers match. If the number of digits of the random number is set sufficiently large, the probability that a malicious third party will accidentally apply this random number can be sufficiently reduced. Further, by periodically changing the random number, it is safe even if the random number is stolen for some reason. That is, safety equivalent to “having the vehicle key” in the fifth embodiment can be realized.

  FIG. 19 is a schematic diagram showing the overall configuration of a vehicle remote monitoring control system according to the sixth embodiment of the present invention. In the figure, a vehicle 1500 is a moving body and includes an in-vehicle unit 1510. The mobile phone 1630 and the in-vehicle unit 1510 perform wireless communication with the base station 1610 constituting the public wide area wireless access network 1600, respectively. The configuration of the in-vehicle unit 1510 mounted on the vehicle 1500 is the same as that of the in-vehicle unit 1210 in the fifth embodiment, except that the communication partner is the monitoring control server 1620 on the public wide area wireless access network 1600. The public wide area wireless access network 1600 is formed by connecting a mobile phone network or a wireless packet communication network and the Internet. The monitoring control server 1620 is connected to the Internet, and communication between the mobile phone 1630 and the monitoring control server 1620 and between the monitoring control server 1620 and the in-vehicle unit 1510 is performed via the public wide area wireless access network 1600. . As a mobile phone network or a wireless packet communication network used for the public wide area wireless access network 1600, for example, a PHS (Personal Handyphone System) network or a packet data communication service provided by NTT Docomo (registered trademark) A DoPa (registered trademark) network or the like.

  FIG. 20 is an overview of the vehicle key 1400 shown in FIG. In the illustrated example, the key 1400 includes an insertion portion 1410 that is inserted into a keyhole of a door lock of the vehicle 1500 to lock or unlock, and a handle portion 1420 that holds the key by hand when locking or unlocking. . The handle portion 1420 is provided with display means 1421 and operation means 1422. This assumes an operation in which a random number is generated by operating the operating means 1422 and the random number is displayed by the display means 1421 (see FIG. 21 described later). Since the information to be displayed is only a random number, the display area may be small as compared with the fifth embodiment. In addition, only one button is sufficient for the operating means 1422 because it only gives an opportunity to generate a random number. In addition to this, there is a method in which the operation unit 1422 is omitted and the random number is periodically updated and displayed on the display unit 1421 (see FIG. 22 described later). On the contrary, there is a method in which the display means 1421 is omitted and the operation means 1422 is operated to transmit a random number to the mobile phone (see FIG. 23 described later). This has the advantage that the display means requiring a relatively large area can be omitted.

21, 22 and 23 are block diagrams of the vehicle key 1400 shown in FIG.
FIG. 21 shows a case where the key 1400 is provided with a display means 1421, an operation means 1422, a random number generation means 1423 for generating a random number by a predetermined algorithm, and a power supply means 1425 for supplying power to each unit.
On the other hand, FIG. 22 shows a case where the operation unit 1422 is omitted from the configuration of FIG. 21 and a display unit 1421, a random number generation unit 1423, and a power supply unit 1425 are provided.
FIG. 23 shows a case where the display unit 1421 is omitted, and an operation unit 1422, a random number generation unit 1423, a random number transmission unit 1424, and a power supply unit 1425 are provided. In FIG. 23, the random number generated by the random number generation unit 1423 is transmitted to the mobile phone 1630 by the random number transmission unit 1424. For the random number transmission means 1424, an IrDA (Infrared Data Association) method or the like is used.

  Next, an operation flow in the vehicle remote monitoring control system shown in FIG. 19 will be described. The monitoring control server 1620 has the same random number generation algorithm as the random number generation means 1423 of the vehicle key 1400, for example, generates the same random number at the same time.

FIG. 24 is a flowchart when the position information of the vehicle 1500 is remotely monitored in the vehicle remote monitoring control system shown in FIG.
The monitoring control server 1620 communicates with the in-vehicle unit 1510 of the vehicle 1500, acquires position information from the in-vehicle unit, and stores it in the internal storage means (step S2210).
On the other hand, when the user presses the button (operation unit 1422) of the key 1400 configured as shown in FIG. 21, the random number generation unit 1423 generates a random number, and the display (display unit 1421) displays the random number (step S2220). . The user visually reads the random number displayed on the display of the key 1400 (step S2230), and inputs the read random number using the numeric keypad of the mobile phone 1630 (step S2240). When the user inputs a location information transmission request transmission instruction to the mobile phone 1630 using the key, the mobile phone 1630 transmits the input random number and the location information transmission request to the monitoring control server 1620 (step S2250). The monitoring control server 1620 checks whether or not the received random number matches the random number generated by itself (step S2260). If the received random number matches the random number generated by the monitoring control server 1620, the monitoring control server 1620 transmits the position information of the vehicle 1500 read from the internal storage means to the mobile phone 1630 (step S2270). The display of the mobile phone 1630 displays the received position information (step S2280).

  In the figure, the monitoring control server 1620 shows a flow in the case where the position information is acquired by communicating with the vehicle-mounted unit 1510 in advance. Acquisition may begin. As a display method of position information, there are latitude and longitude, display on a map, display by a relative position from a key, and the like.

  FIG. 25 shows a flowchart of remote control (door lock locking) in the vehicle remote monitoring control system shown in FIG. As shown in FIG. 18, except that the key generates a random number, thereby identifying that the communication is from the key owner, and that the communication function and the information display function use those of the mobile phone 1630. This is similar to the case of the door lock locking of the fifth embodiment.

  That is, as in steps S2220 to S2240 in FIG. 24, the user visually reads the random number displayed on the display by pressing a button of the key 1400, and inputs the random number to the mobile phone 1630 with the numeric keypad (steps S2310 to S2330). Furthermore, when the user inputs a door lock locking request transmission instruction to mobile phone 1630 using the key, mobile phone 1630 transmits the input random number and the door lock locking request to monitoring control server 1620 (step S2340). . The monitoring control server 1620 checks whether or not the received random number matches the random number generated by itself (step S2350), and if it matches, transmits a door lock locking request to the in-vehicle unit 1510 of the vehicle 1500 (step S2350). S2360).

  When the in-vehicle unit 1510 receives the door lock locking request, it transmits the door lock locking request to the door lock system of the vehicle 1500 (step S2370). When the door lock system locks the door lock of the vehicle 1500 (step S2380), the door lock system returns a door lock lock confirmation to the in-vehicle unit 1510 (step S2390). When receiving the door lock locking confirmation, the in-vehicle unit 1510 transmits the door lock locking confirmation to the monitoring control server 1620 (step S2400). When the monitoring control server 1620 receives the door lock locking confirmation, the monitoring control server 1620 transmits the door lock locking confirmation to the mobile phone 1630 (step S2410). When the cellular phone 1630 receives the door lock locking confirmation, it displays completion of door lock locking on its own display (step S2420).

“Door lock locking request” can be read as “Door lock unlocking request” or “Door lock locking status request”, and “Door lock locking confirmation” can be read as “Door lock unlocking confirmation” or “Door lock locking status information”. For example, the door lock locking control and the remote monitoring of the locked state can be performed by the same flow as in FIG.
Further, when performing remote control or remote monitoring of the in-vehicle air conditioning system, “door lock system” may be read as “air conditioning system” in the flowchart shown in FIG.

  In the above, position information and temperature are described as the vehicle monitoring target. However, information obtained by a humidity sensor, a human sensor, a light / dark sensor, or the like can be considered depending on market needs. Obviously, these are within the scope of the present invention.

  In the present embodiment, a method of avoiding the space limitation of the key by using the communication function and the information display function of a portable information communication terminal such as a cellular phone has been shown. This method is not limited to a vehicle key, but can be extended to a general key. That is, the present invention can also be applied to the lock state notification method shown in the above embodiment.

  In the present embodiment, the mobile phone 1630 and the monitoring control server 1620 communicate with each other, and the mobile phone 1630 and the in-vehicle unit 1510 do not directly communicate with each other. However, the monitoring control server 1620 is not provided, and the mobile phone 1630 and the in-vehicle unit 1510 have no communication. A configuration in which the devices directly communicate with each other is also conceivable. In this case, the in-vehicle unit 1510 performs random number generation and user terminal authentication using the random number. Since the monitoring control server 1620 is unnecessary, there is an advantage that the cost of construction and operation of the entire system can be suppressed. However, in the present embodiment, since it is necessary to synchronize the time of the random number generation algorithm, the configuration in which the monitoring control server 1620 in which the power supply and other operating environments have a stable operating environment is responsible for random number generation provides the system stability. From the viewpoint of

  FIG. 26 shows a flowchart of remote monitoring of position information when the mobile phone 1630 and the in-vehicle unit 1510 directly communicate with each other. Similar to steps S2220 to S2240 in FIG. 24, the user visually reads a random number displayed on the display by pressing a button of the key 1400, and inputs the random number to the mobile phone 1630 with the numeric keypad (steps S2510 to S2530). Furthermore, when the user inputs a location information transmission request transmission instruction to mobile phone 1630 using the key, cellular phone 1630 transmits the input random number and the location information transmission request to in-vehicle unit 1510 (step S2540). The in-vehicle unit 1510 confirms whether the received random number matches the random number generated by itself (step S2550), and if it matches, acquires the position information (step S2560) and notifies the mobile phone 1630 ( Step S2570). The display of the mobile phone 1630 displays the received position information (step S2050).

  In the flow of FIGS. 24 to 26 described above, the case where the key 1400 having the configuration shown in FIG. 21 is used has been described. However, when the key 1400 having the configuration shown in FIG. Since the random number generated by the random number generation unit 1423 at a certain timing is displayed on the display unit 1421, the user inputs the currently displayed random number to the mobile phone 1630. When the key 1400 having the configuration shown in FIG. 23 is used, when the button 1422 is pressed, the random number generation unit 1423 generates a random number, and the random number transmission unit 1424 transmits the random number to the mobile phone 1630. There is no need to input a random number to the mobile phone 1630.

  In addition, this type of remote monitoring and control system equipped with a communication function incorporates a mechanism that protects against security threats such as eavesdropping and spoofing by malicious third parties by performing mutual authentication and encryption. It is common that Also in the present embodiment, it is desirable to provide these security functions for communication between the mobile phone 1630 and the in-vehicle unit 1510 or the monitoring control server 1620.

  Note that the above-described key 1100, in-vehicle units 1210 and 1510, the monitoring control server 1620, and the mobile phone 1630 each have a computer system. The operation processes of the control unit 1123 of the key 1100, the control unit 1211 of the in-vehicle unit 1210, the in-vehicle unit 1510, the monitoring control server 1620, and the mobile phone 1630 are stored in a computer-readable recording medium in the form of a program. When the computer system reads out and executes this program, the above processing is performed. The computer system here includes an OS and hardware such as peripheral devices.

Further, the “computer system” includes a homepage providing environment (or display environment) if a WWW system is used.
The “computer-readable recording medium” refers to a portable medium such as a flexible disk, a magneto-optical disk, a ROM, and a CD-ROM, and a storage device such as a hard disk built in the computer system. Furthermore, the “computer-readable recording medium” dynamically holds a program for a short time like a communication line when transmitting a program via a network such as the Internet or a communication line such as a telephone line. In this case, a volatile memory in a computer system serving as a server or a client in that case, and a program that holds a program for a certain period of time are also included. The program may be a program for realizing a part of the functions described above, and may be a program capable of realizing the functions described above in combination with a program already recorded in a computer system.

  The present invention relates to an administrator (a machine corresponding to a key) located in a remote place for a door of a house, a car door, a gas tap, a window key, and other objects whose state can be changed by a mechanical device corresponding to the key. This is used when notifying a person who has changed the state of the object using an instrument). It is also used for remote monitoring and transmission of control information of systems that require keys to operate automobiles, motorcycles, certain machine tools, and computers with security measures.
