According to the open / close control, the lock is automatically opened or closed, or the lock can be manually opened / closed.

There is known a keyless entry system in which a security code is used as a signal for performing the electronic lock opening / closing control, preventing accidental opening / closing of a door by a user having the same security code, and improving security (for example, Patent Document 1). This keyless entry system is a system for controlling the opening and closing of a key of a vehicle such as an automobile, and each time an operation switch is operated, a transmitter that transmits a transmission code including a password is received, and the transmission code is received and transmitted. And a receiver that outputs an operation signal corresponding to the transmission code on condition that the code code matches the reference code. Each time the operation switch is operated, the transmitter calculates and updates the code according to a predetermined function, and transmits a transmission code including the code. Each time the transmission code is received, the receiver calculates and updates the reference code according to the same function as the transmitter. If the code and reference code do not match at the receiver, the receiver temporarily stores this transmission code. Only when the user inserts a legitimate key into the door key cylinder within a predetermined time and the door lock state changes, the code of this transmission code is regarded as the matched code, and the receiver is used as the reference code. Will be re-registered. Since users having the same password do not have a regular key, accidental opening and closing of the door is prevented. In addition, the case where the user does not press the operation switch of the transmitter is included when the password code and the reference code do not match.

  FIG. 7 shows the operation of each communicator at the time of lock opening / closing control in the electronic lock system 1 in time series. It is assumed that the storage unit 40 of the lock control communication device 4 stores its own ID information such as IDxx, for example. When the user starts the lock opening / closing operation, the user communication device 2 and the lock control communication device 4 possessed by the user start communication.

  (1) First, the lock control communication device 4 performs an operation of reading the ID information of the user communication device 2 from the address 1 (# 1) of the storage unit 20 of the user communication device 2. (2) The user communication device 2 causes the lock control communication device 4 to load its own ID information such as IDxx, for example. The lock control communication device 4 collates this ID information of the user communication device 2 with its own ID information. Since these pieces of ID information are IDxx and match, the electronic lock 3 can be opened and closed. The address 1 is an address in which ID information that is collated with the ID information of the lock control communication device 4 for opening / closing control of the electronic lock 3 is stored.

(9) The user communication device 2 causes the ID conversion communication device 5 to load the ID information IDxy stored at the address 2. (10) The ID conversion communication device 5 writes this ID information IDxy to the address 1 of the user communication device 2 and is collated with the ID information of the lock control communication device 4 for opening / closing control of the electronic lock. ID information is newly set. In this way, the ID information of the user communication device 2 is converted.

  It is assumed that the user communication device 2 communicates with the lock control communication device 4 in order to open and close the electronic lock 3 after the ID information conversion of the user communication device 2. (11) The lock control communication device 4 performs an operation of reading the ID information of the user communication device 2 from the address 1 of the storage unit 20 of the user communication device 2. (12) The user communication device 2 causes the lock control communication device 4 to load its own ID information IDxy. The lock control communication device 4 collates this ID information of the user communication device 2 with its own ID information. Since the ID information of the lock control communication device 4 is IDxy, the ID information of these communication devices is the same. As a result, the electronic lock 3 can be opened and closed.

  Thus, when the ID information of the lock control communication device 4 and the ID information of the user communication device 2 do not match, the ID lock communication device 5 does not set the ID information of the user communication device, and the electronic lock 3 is Since it cannot be opened and closed, security can be improved. Moreover, since the ID conversion communication device 5 is owned by the system administrator and the ID information of the user communication device is not rewritten by the user, it is possible to prevent rewriting of the ID information by a malicious user and to improve security. Can do.

When this communication is successful and the lock control communication device 4 can acquire the ID information of the user communication device 2 (Yes in S103), the lock control communication device 4 determines the ID information of itself and the ID information of the user communication device 2. Are collated (S104). When the communication is not successful (No in S103), an LED (not shown) provided in the lock control communication device 4 blinks to notify the user of the occurrence of an error. Thereafter, the operation of S102 is performed again.

  If the ID information matches as a result of the collation (Yes in S105), the unlocking of the electronic lock 3 is controlled (S106). The unlocking control allows the user to rotate the knob portion 31 of the electronic lock 3 and open the door or the like to which the electronic lock 3 is attached. After the electronic lock 3 is controlled to be unlocked, if the user does not open the door or the like (No in S107) and a predetermined time has passed (Yes in S108), the electronic lock 3 is automatically locked and the electronic lock is again displayed. 3 is performed again, the operation of S102 is performed again (S109). While the predetermined time has not elapsed (No in S108), the electronic lock 3 stands by in an unlocked state. On the other hand, after the electronic lock 3 is unlocked, when the user opens the door or the like (Yes in S107) and then closes the door or the like (Yes in S110), the electronic lock 3 is automatically locked. (S109). After the user opens the door or the like, while the door is not closed (No in S110), the electronic lock 3 stands by in an unlocked state.

  If the ID information does not match as a result of the collation (No in S105), the lock control communication device 4 starts communication to write its own ID information to the address 2 of the user communication device 2 (S111). If this communication is not successful (No in S112), the above LED blinks, an error is notified to the user, and a repetitive writing operation is performed. When this communication is successful and the writing of the ID information is completed (Yes in S112), the LED is turned on to notify the user of the success.

  Assume that the administrator communicates the ID conversion communication device 5 and the user communication device 2 possessed after the completion of writing the ID information. The ID conversion communication device 5 starts an operation of reading ID information from the address 2 of the user communication device 2 (S113). If this communication is successful and ID information can be acquired (Yes in S114), the ID conversion communication device 5 starts an operation of writing this ID information in the address 1 of the user communication device 2 (S115). Address 1 is an address in which ID information that is collated with the lock control communication device 4 is stored for opening / closing control of the electronic lock 3. When the above communication is successful and the ID information is written in the user communication device 2 (Yes in S116), an LED (not shown) provided in the ID conversion communication device 5 is turned on, and the communication success is indicated to the administrator. Notification is made (S117). When the user performs the opening / closing operation of the electronic lock 3 again after writing the ID information to the address 1 of the user communication device 2, the operation of S102 is performed again. When reading or writing of ID information by the ID conversion communication device 5 is not successful (No in S114, No in S116), the above LED blinks and an error is notified to the administrator (S118). Thereafter, the operation of S113 is performed again.

  FIG. 9 shows the contents of the ID information writing operation (corresponding to S111 in FIG. 8) and the reading operation of the written ID information (corresponding to S115 in FIG. 8) in the above-described lock opening / closing control. The contents are shown in detail. When the control unit 47 of the lock control communication device 4 transmits its own ID information to the user communication device 2, this control unit 47 encrypts this ID information (S201) and writes this ID information in the address 2 of the user communication device 2 (S202). ). This encryption is performed based on ID information before the change by the ID changing unit 48, for example. Thus, since the ID information is encrypted, the leakage of the ID information can be prevented when the user communication device 2 is stolen, and the security can be improved.

  The lock control communication device 4 writes its own ID information in the address 2 of the user communication device 2 when the ID information of the address 1 of the user communication device 2 and its own ID information do not match. The address 1 stores ID information that is collated with the ID information of the lock control communication device 4. The mismatch of the ID information occurs, for example, when the ID information of the lock control communication device 4 is updated by the ID changing unit 48. If the ID information does not match, the ID information of the address 2 needs to be written to the address 1 in order to match the ID information of the lock control communication device 4 and the ID information of the user communication device 2. Therefore, the control unit 57 of the ID conversion communication device 5 reads the encrypted ID information from the address 2 of the user communication device 2 (S203), and decrypts this ID information (S204). Further, the control unit 57 writes the decrypted ID information to the address 1 of the user communication device 2 (S205).

  FIG. 10 shows a method for unifying ID information of the communication devices when a plurality of lock control communication devices 4 are provided in the electronic lock system 1. The electronic lock system 1 further includes a communication line 7 (communication means) that connects a plurality of lock control communication devices 4 in a communicable manner. The communication line 7 includes, for example, a local area network (LAN), a wireless LAN, a power line that supplies power to the lock control communication device 4, or RS-485.

  The plurality of lock control communication devices 4 are connected to each other via a communication line 7 so that they can communicate with each other, and one of them is set as a master. The master setting is performed, for example, by connecting the communication line 7 to one master terminal among the plurality of lock control communication devices 4 provided with the master terminal. The control unit 47 of the lock control communication device 4 having the communication line 7 connected to the master terminal detects this connection and recognizes that it has been set as a master.

  When the power of the lock control communication device 4 set as the master is turned on, (1) only the ID changing unit 48 of the communication device changes the ID information of the communication device to new ID information. Here, it is assumed that the new ID information is set to IDxx. (2) After setting the ID information, the control unit 47 of the lock control communication device 4 set as the master instructs the other lock control communication device 4 to set the ID information to IDxx via the communication line 7. An instruction signal is transmitted. (3) Upon receiving this instruction signal, the control unit 47 of the lock control communication device 4 sets its own ID information as the new ID information IDxx. In this way, the ID information of the other lock control communication devices 4 is set by the lock control communication device 4 set as the master.

  With the configuration as described above, only the lock control communication device 4 set as the master creates new ID information, and the ID information is transferred to the other lock control communication device 4 via the communication line 7, and all lock control communication is performed. The ID information of the machine 4 can be unified. As a result, a plurality of electronic locks can be opened and closed using the same user communication device.

  Next, an electronic lock system according to a second embodiment of the present invention will be described with reference to FIGS. 11 to 13. The electronic lock system of this embodiment is different from the above embodiment in that the ID conversion communication device 5 further includes a storage unit and a switch unit.

  FIG. 11 shows the configuration of the ID conversion communication device 5. Compared with the ID conversion communication device 5 of the above embodiment (see FIG. 5), the ID conversion communication device 5 of the present embodiment stores a storage unit 50 (stores various information including ID information transmitted and received with the user communication device 2). Storage means) and a switch unit 60 (operation means) that can be pushed down by the user.

  The storage unit 50 includes a volatile memory such as a RAM for temporarily storing ID information read from the user communication device 2. The control unit 57 can store the ID information read from the user communication device 2 in the storage unit 50, further read the ID information stored in the storage unit 50, and write it in the user communication device 2. Thus, since the ID information is stored in the volatile memory, when these communication devices are disassembled and the memory is taken out, power is not supplied to the memory, and the ID information stored in the memory is lost. Information cannot be read. Therefore, when the ID conversion communication device 5 is stolen, leakage of ID information can be prevented and security can be improved.

  The storage unit 50 also includes a ROM (Read Only Memory), and this ROM stores a program for decrypting the encrypted ID information. When the ID information read from the user communication device 2 is encrypted, the control unit 57 uses this program to decrypt the ID information.

  The switch unit 60 includes a switch, a button, or a key. The control unit 57 reads the ID information of the address 2 of the user communication device 2 when communicating with the user communication device 2 while the switch, button, or key is pressed by the user and the switch unit 60 is being operated. At the same time, the ID information is stored in the storage unit 50. When communicating with the user communication device 2 while the switch unit 60 is not operated, the ID information stored in the storage unit 50 is written to the address 1 of the user communication device 2.

  12 (a), 12 (b), and 12 (c) show an overview of the ID conversion communication device 5, and FIG. 12 (d) shows the case where the ID conversion communication device 5 and the user communication device 2 are electrically connected. Show the state. Various memories constituting the storage unit 50 are housed in a housing 58. The switch unit 60 is provided on the surface of the housing 58 so that the user can press it down.

If the ID information stored in the address 1 of the user communication device 2 is different from the ID information stored in the storage unit 40 of the lock control communication device 4, an authentication error occurs. Here, ID information stored in the address 1 is IDxx, and ID information of the lock control communication device 4 is IDxy. IDxx and IDxy are different ID information.

  (1) When an authentication error occurs, the lock control communication device 4 automatically writes its own new ID information IDxy in the address 2 (# 2) of the user communication device.

  Assume that the user communication device 2 and the ID conversion communication device 5 communicate with each other while the user operates the switch unit 60 of the ID conversion communication device 5 and presses the button. While the button is pressed, (2) the ID conversion communication device 5 starts an operation of reading the ID information written in the address 2 of the user communication device 2 by the lock control communication device 4. (3) The user communication device 2 causes the ID conversion communication device 5 to load the ID information IDxy stored at the address 2, and the storage unit 50 of the ID conversion communication device 5 stores the IDxy.

  Assume that after reading the ID information from address 2, the user stops pressing the button and stops the operation of the switch unit 60. When the ID conversion communication device 5 communicates with the user communication device 2 while the switch unit 60 is not operated, (4) the ID information stored in the storage unit 50 is written to the address 1 of the user communication device 2, For the opening / closing control of the electronic lock, the ID information of the user communication device 2 that is collated with the ID information of the lock control communication device 4 is newly set. Thus, the ID information reading operation from the user communication device 2 and the ID information writing operation to the user communication device 2 in the ID conversion communication device 5 are performed separately according to the operation of the switch unit 60. The ID information of the user communication device 2 is converted by this ID information writing operation.

  It is assumed that the user communication device 2 communicates with the lock control communication device 4 in order to open and close the electronic lock 3 after the ID information conversion of the user communication device 2. (5) The lock control communication device 4 performs an operation of reading the ID information of the user communication device 2 from the address 1 (# 1) of the storage unit 20 of the user communication device 2. (6) The user communication device 2 causes the lock control communication device 4 to load its own ID information IDxy. The lock control communication device 4 collates this ID information of the user communication device 2 with its own ID information. Since the ID information of the lock control communication device 4 is IDxy, the ID information of these communication devices is the same. As a result, the electronic lock 3 can be opened and closed.

  As described above, in the ID conversion communication device 5, the ID information reading operation from the user communication device 2 and the ID information writing operation to the user communication device 2 can be performed separately. Is provided, ID information can be read from one user communication device 2 and then the information can be written to a plurality of user communication devices 2. For this reason, when a plurality of user communication devices 2 are provided, the ID information of the user communication device 2 can be easily changed.

  Next, an electronic lock system according to a third embodiment of the present invention will be described with reference to FIGS. The electronic lock system according to the present embodiment is different from the above-described embodiment in that the lock control communication device 4 further includes a switch unit that is operated by the user in order to update the ID information.

The switch unit 49 includes a switch, a button, or a key, and instructs the control unit 47 to create new ID information using the above program based on a user operation.

  Based on an instruction from the switch unit 49, the ID changing unit 48 of the control unit 47 updates the ID information based on the pseudo random number generated by the above program, and creates new ID information. For this reason, ID information can be made difficult to decipher and security can be improved. Further, since the new ID information is created when the user operates the switch unit 49, the ID information of the lock control communication device can be updated at any time.

  FIG. 15 shows the operation of the lock control communication device 4 when updating the ID information. Here, ID information of the lock control communication device 4 is IDxx. (1) When the user operates the switch unit 49 of the lock control communication device 4, (2) the control unit 47 executes a program for generating random numbers, and the ID changing unit 48 generates a pseudo-data generated by this program. Based on the random number, the ID information is updated to the new ID information. For example, if the new ID information is IDxy, the ID information stored in the storage unit 40 is changed to the new ID information IDxy.

  FIG. 16 shows a method of unifying ID information of the communication devices when a plurality of lock control communication devices 4 are provided in the electronic lock system 1. The plurality of lock control communication devices 4 can communicate with each other via the communication line 7.

  (1) It is assumed that the user operates the switch unit 49 of an arbitrary lock control communication device 4. It is assumed that the ID information of this communication device before operation is IDxx. (2) Based on the operation of the switch unit 49, the ID changing unit 48 of the communication device changes the ID information of the communication device to new ID information. Here, it is assumed that the new ID information is set to IDxy. (3) After setting the ID information, the control unit 47 of the lock control communication device 4 operated by the switch unit 49 rewrites the ID information to IDxy in the other lock control communication device 4 via the communication line 7. An instruction signal for instructing is transmitted. (4) Upon receiving this instruction signal, the control unit 47 of the lock control communication device 4 changes its own ID information to the new ID information IDxy. Thus, the lock control communication device 4 whose ID information has been changed by the user's operation rewrites the ID information of the other lock control communication device 4 with its own new ID information via the communication line 7.

  With the above configuration, when the user updates the ID information of one lock control communication device 4, the ID information is transferred to the other lock control communication device 4 via the communication line 7, and all lock control communication devices are transferred. 4 ID information can be unified. As a result, a plurality of electronic locks can be opened and closed using the same user communication device.

  Next, a fourth embodiment of the present invention will be described with reference to FIGS. The electronic lock system of this embodiment is different from the above-described embodiment in that the lock control communication device 4 further includes a count unit that counts according to time.

  The ID changing unit 48 creates new ID information based on the value of the counter. For example, the lock control communication device 4 creates new ID information based on the value of the counter when it first communicates with the user communication device 2 after the power is turned on.

  FIG. 18 shows a procedure for updating the ID information of the lock control communication device 4 by the ID changing unit 48. When the lock control communicator 4 is powered on, the counter value of the count unit 70 is set to 0 (S301), and then the counter value is incremented as the specified time elapses (S301). When the lock control communication device 4 starts the first communication with the user communication device 2 after the power is turned on and starts the operation of reading the ID information from the user communication device 2 (S303). ), The ID changing unit 48 generates new ID information in accordance with the counter value. The old ID information is changed to new ID information, and the ID information is updated (S505). If the above communication fails (No in S504), the operation in S302 is performed again.

  In this way, by creating new ID information of the lock control communication device 4 according to an indefinite elapsed time from the time of power-on to the first communication of the lock control communication device 4, ID information that is difficult to decipher can be obtained. Can be created. As a result, security can be improved. Further, since the new ID information is created when the lock control communication device 4 performs communication for the first time, the ID information can be automatically updated.

  Next, a fifth embodiment of the present invention will be described with reference to FIG. Compared with the above embodiment, the electronic lock system of the present embodiment includes a switch unit operated by the user to update the ID information, a count unit that performs counting according to time, It differs in that it further comprises.

The difference is that the switch unit 49 includes a count unit 70 that counts according to the elapsed time from a specific time.

  The switch unit 49 includes a switch, a button, or a key, and outputs an instruction signal instructing creation of ID information to the ID changing unit 48 of the control unit 47 based on a user operation.

  The count unit 70 is provided in the control unit 47 and includes a timer that measures time and a counter that counts according to the time measured by the timer. For example, the timer measures an elapsed time from when the lock control communication device 4 is turned on, and the counter is incremented every time a specified time elapses.

  Based on the instruction signal from the switch unit 49, the ID changing unit 48 creates new ID information based on the value of the counter when the instruction signal is received. Since it is indefinite when the user operates the switch unit 49, for example, new ID information of the lock control communication device 4 is created according to the elapsed time from when the lock control communication device 4 is powered on to when the switch unit 49 is operated. By doing so, ID information that is difficult to decipher can be created. For this reason, security can be improved. Further, since the new ID information is created when the user operates the switch unit 49, the ID information of the lock control communication device 4 can be updated at any time.
