For example, a mobile phone control program for transmitting and receiving data to and from the ID management server 404 is downloaded from, for example, a program download server device managed by a mobile phone operator. Alternatively, the mobile phone control program is stored in the storage unit 105 included in the electronic key device 101, and the mobile phone 301 is configured to execute the mobile phone control program stored in the storage unit 105. Good.

  FIG. 6 is a flowchart for explaining the operation of the electronic key system 1. First, the user operates the operation unit 304 of the mobile phone 301 to which the electronic key device 101 is attached, and the operation unit 304 changes the initial ID of the electronic lock device 201 and the ID change requesting the change of the current ID in the electronic lock device 201. The request is accepted (step S101). The initial ID can be acquired by the user, for example, by being described in a rental contract of a weekly apartment or by being described in the case of the padlock 223 if the electronic lock device 201 has a form such as a padlock 223. ing.

  Then, the instruction signal (operation instruction information) indicating the initial ID and the ID change request received by the operation unit 304 is sent to the external interface unit 302 in the mobile phone 301 and the mobile phone interface unit 112 in the electronic key device 101 shown in FIG. The communication frame including the initial ID, the current ID request command for requesting the current ID of the electronic lock device 201, and the CRC calculated by the CRC calculation unit 107. Is generated and output to the transmission unit 108, and the transmission unit 108 converts the communication frame into a radio signal, which is emitted from the antenna 109 to the space (step S102).

  Next, in the electronic lock device 201 shown in FIG. 3, the wireless signal emitted from the antenna 109 in the electronic key device 101 to the space is received by the antenna 202 in the electronic lock device 201, and the wireless signal is transmitted to the communication frame by the receiving unit 203. Demodulated. The demodulated communication frame is stored in the shift register 204 while being shifted bit by bit, and the CRC calculation unit 205 calculates the CRC.

  When the initial ID is stored in the shift register 204, the matching unit 207 compares the initial ID stored in the shift register 204 with the current ID of the electronic lock device 201 stored in the storage unit 206. A signal indicating the comparison result is transmitted to the control unit 208. In this case, since the current ID is in an initial state, the current ID is equal to the initial ID.

  Next, if the control unit 208 indicates that the signal from the matching unit 207 does not match, the received communication frame is not addressed to itself, so the reception operation is terminated (NO in step S103), while the signal from the matching unit 207 is Indicates a match (YES in step S103), since the received communication frame is addressed to itself, the reception operation is continued and the current ID request command is stored in the shift register 204. Existence is confirmed.

  Next, the control unit 208 checks whether or not the initial ID stored in the storage unit 206 is equal to the current ID (NO in step S104), and the current ID is not in the initial state but is already a new one. Since the ID is registered, the process is terminated to cancel the current ID request command transmitted from the electronic key device 101. If the IDs are equal (YES in step S104), the electronic lock device 201 is initialized by the control unit 208. A communication frame including the initial ID stored in the storage unit 206 is output to the transmission unit 209 to indicate that the state (current ID can be changed), and the communication unit converts the communication frame into a radio signal. Then, it is emitted from the antenna 202 to the space (step S106).

  In this case, after a new ID is registered in the electronic lock device 201 and the current ID is changed to an ID different from the initial ID, the current ID request command is canceled by the control unit 208 in step S104. Thus, after a new ID is registered in the electronic lock device 201, the current ID of the electronic lock device 201 is prevented from being illegally changed by a third party.

  Next, a radio signal emitted from the antenna 202 in the electronic lock device 201 to the space is received by the antenna 109 in the electronic key device 101 shown in FIG. 2, and the radio signal is demodulated into a communication frame by the receiving unit 111. Then, the initial ID of the electronic lock device 201 acquired by the control unit 106 from the demodulated communication frame is output to the mobile phone 301 via the mobile phone interface unit 112 and the external interface unit 302. Then, the initial ID of the electronic lock device 201, the telephone number (mobile ID) of the mobile phone 301, and the electronic lock device 201 are transferred from the mobile phone 301 to the ID management server 404 via the mobile phone network 401, the router 402, and the LAN 403. A new ID issuance request command requesting issuance of a new ID is transmitted (step S107).

  Next, the user who received the initial ID transmitted from the mobile phone 301, the telephone number of the mobile phone 301, and the new ID issue request command by the ID management server 404 shown in FIG. 1, and transmitted the new ID issue request command. The received telephone number of the mobile phone 301 is compared with the telephone number 453 stored in the ID management storage unit 405 to confirm whether or not the user is an appropriate user who has made a lease agreement for a weekly apartment. (Step S108).

  If the result of the comparison by the ID management server 404 is a mismatch, the ID management server 404 determines that the user who transmitted the new ID issuance request command is not an appropriate user who has made a lease agreement for a weekly apartment, When the processing ends (NO in step S108), the ID management server 404 determines that the user who transmitted the new ID issuance request command is an appropriate user who has executed a lease contract for the weekly apartment (step NO). The process proceeds to step S110 to confirm whether or not the electronic lock device 201 is in an initial state (a state where a new ID can be registered).

  As described above, the telephone number 453 of the cellular phone 301 of the user who has previously contracted the weekly apartment stored in the ID management storage unit 405 and the telephone number of the cellular phone 301 that has transmitted the new ID issue request command must match. For example, the new ID issue request command is canceled by the ID management server 404, and the process ends, so that the current ID of the electronic lock device 201 is changed by a third party other than the appropriate user who contracts the weekly apartment. Can be prevented. Instead of the phone number of the mobile phone 301, an ID known as a so-called mobile phone wireless ID unique to each mobile phone 301 may be used as the mobile ID.

  Next, in step S110, the ID management server 404 checks whether or not the initial ID 451 stored in the ID management storage unit 405 is equal to the current ID 452, and if not equal (NO in step S110), the current ID is Since the new ID is already registered instead of the initial state, the process ends to cancel the new ID issuance request command transmitted from the mobile phone 301, while if equal (YES in step S110), the ID management server 404 A new current ID is generated and stored in the ID management storage unit 405 as a current ID 452. Then, by the ID management server 404, a new current ID, an initial ID and a telephone number transmitted from the mobile phone 301, and a current ID change command (ID change instruction) that instructs the electronic lock device 201 to register a new current ID. Information) is transmitted to the mobile phone 301 via the LAN 403, the router 402, and the mobile phone network 401 (step S111).

  In this case, the ID management server 404 stores the new current ID as the current ID 452 in the ID management storage unit 405, and after the current ID 452 is changed to an ID different from the initial ID 451, the ID management server 404 performs the current ID in step S110. Since the request command is canceled, a new current ID is stored as the current ID 452 in the ID management storage unit 405 in response to the current ID request command transmitted by the appropriate user by the ID management server 404, and then by a third party. In response to the transmitted current ID request command, a new current ID is prevented from being issued illegally.

  Next, a new current ID, initial ID, telephone number, and current ID change command transmitted from the ID management server 404 by the mobile phone 301 shown in FIG. 2 are received, and the external interface unit 302 and the mobile phone are received from the mobile phone 301. An initial ID, a new current ID, and a current ID change command are output to the control unit 106 via the interface unit 112, and the new current ID is stored in the storage unit 105 by the control unit 106. An initial ID, a new current ID, and a current ID change command are transmitted as a radio signal to the electronic lock device 201 via the transmitting unit 108 and the antenna 109 in order to request registration of a new current ID as in step S102. (Step S112).

  Next, the wireless signal emitted from the antenna 109 in the electronic key device 101 to the space is received by the antenna 202 in the electronic lock device 201 shown in FIG. The new current ID and the current ID change command are demodulated and output to the control unit 208. Then, the control unit 208 stores a new current ID in the storage unit 206 as the current ID of the electronic lock device 201 in accordance with the current ID change command (step S113).

  Next, the lock opening / closing operation in the electronic key system 1 will be described. FIG. 7 is a flowchart showing an example of the lock opening / closing operation in the electronic key system 1. First, the user operates the operation unit 304 of the mobile phone 301 to which the electronic key device 101 is attached, and the operation unit 304 receives a lock opening / closing instruction for instructing the lock opening / closing operation to the electronic lock device 201 (step S201).

  Then, the instruction signal indicating the lock opening / closing instruction received by the operation unit 304 is acquired by the control unit 106 via the external interface unit 302 in the cellular phone 301 and the cellular phone interface unit 112 in the electronic key device 101 shown in FIG. Is done. Further, the control unit 106 obtains the current ID of the electronic lock device 201 stored in the storage unit 105 in step S112 and the lock opening / closing command (opening / closing instruction information) corresponding to the lock opening / closing instruction received by the operation unit 304. The wireless signal is transmitted from the control unit 106 to the electronic lock device 201 via the transmission unit 108 and the antenna 109 in the same manner as in step S102 (step S202).

  In addition, although the example in which the current ID of the electronic lock device 201 and the lock opening / closing command stored in the storage unit 105 are transmitted to the electronic lock device 201 by the control unit 106 has been shown, the user uses the operation unit 304 to The input ID may be transmitted as the current ID. When there are a plurality of electronic lock devices 201, the control unit 106 stores the current ID of each electronic lock device 201 in the storage unit 105 through the processing of steps S101 to S113, and the user performs a lock opening / closing operation. At this time, a plurality of current IDs stored in the storage unit 105 are displayed in a list on the display unit 303, and the current ID selected from the ones displayed on the display unit 303 is transmitted when the user operates the operation unit 304. You may make it do. Accordingly, a lock opening / closing command can be transmitted to a plurality of electronic lock devices 201 using one mobile phone 301 and electronic key device 101.

  Further, when the control unit 106 stores a plurality of current IDs in the storage unit 105, the control unit 106 associates each lock ID with the current ID, which is the name of each electronic lock device 201 set so as to be easily understood by the user. When the user performs a lock opening / closing operation, a plurality of lock names stored in the storage unit 105 are displayed in a list on the display unit 303 and displayed on the display unit 303 by the user operating the operation unit 304. The lock name selected from the obtained lock names may be acquired, and the current ID stored in association with the acquired lock name may be transmitted based on the correspondence stored in the storage unit 105. Thus, the electronic lock device 201 that is to perform the lock opening / closing operation can be selected by the name set so that the user can easily understand, and the operability can be improved.

  Next, the radio signal emitted from the antenna 109 in the electronic key device 101 to the space is received by the antenna 202 in the electronic lock device 201 shown in FIG. 3, and the current ID and the lock opening / closing command are received from the radio signal by the receiving unit 203. Demodulated and output to the control unit 208. Similarly to step S103, the matching unit 207 compares the current ID demodulated by the receiving unit 203 with the current ID of the electronic lock device 201 stored in the storage unit 206, and a signal indicating the comparison result. Is transmitted to the control unit 208.

  Next, when the control unit 208 indicates that the signal from the matching unit 207 does not match (NO in step S203), the received communication frame is not addressed to itself, so the reception operation is terminated, while the signal from the matching unit 207 is Indicates a match (YES in step S203), since the received communication frame is addressed to itself, is the current ID changed from the initial ID and is the electronic lock device 201 ready to accept the key opening / closing command? The process proceeds to step S204 to confirm whether or not.

  Next, in step S204, the control unit 208 confirms whether or not the initial ID stored in the storage unit 206 is equal to the current ID. If they are equal (YES in step S204), the ID management server 404 is set as the current ID. The ID management server determines that the issued ID is not registered and terminates the process to cancel the lock opening / closing command transmitted from the electronic key device 101, but if not equal (NO in step S204), the ID management server as the current ID It is determined that the ID issued by 404 is registered and the key opening / closing command can be accepted, and the process proceeds to step S206 to execute the key opening / closing command.

  Next, in step S206, the controller 208 executes a lock opening / closing command. That is, when the lock opening / closing command indicates an instruction to open the lock, the actuator 211 is driven by the control unit 208 to unlock the lock mechanism 212, while the lock opening / closing command closes the lock. When the instruction is given, the actuator 211 is driven by the control unit 208 to lock the lock mechanism unit 212.

  As described above, after the new ID issued by the ID management server 404 is stored as the current ID in the storage unit 206 of the electronic lock device 201 by the process of step S203, the radio signals other than the radio signal including the new ID are received. Therefore, only a user who possesses the electronic key device 101 whose new ID is stored in the storage unit 105 transmits a lock open / close command to the electronic lock device 201 to unlock and lock the lock mechanism unit 212. It is possible to improve the reliability of the electronic lock device 201 as a lock.

  Further, by the processing in step S204, the lock opening / closing command is not executed when the new ID issued by the ID management server 404 is not stored as the current ID in the storage unit 206 of the electronic lock device 201. Even if a lock opening / closing command is transmitted to the device 201 using the initial ID, the lock mechanism 212 cannot be unlocked or locked, so that the reliability of the electronic lock device 201 as a lock can be improved.

  In addition, the user causes the electronic key system 1 to execute the current ID registration process in steps S101 to S113, thereby using the electronic key device 101 connected to his / her mobile phone 301 to connect the weekly device to which the electronic lock device 201 is attached.
