Description

  The present invention relates to an electronic lock system, an electronic lock, and a server.

  Conventionally, locks are used for various purposes at construction sites. For example, in order to prevent outsiders from entering the construction site before starting work or after finishing work, a partition fence (for example, a temporary fence) is provided at the entrance of the construction site, and an opening / closing part (for example, a door part) of the partition fence is provided. A lock is used to lock. Alternatively, a lock is used to lock a work box containing tools and electronic equipment.

  Since many site workers often go in and out at construction sites, generally, locks used at construction sites are locked or unlocked using a key (hereinafter referred to as “lock operation”). Locks to do are not suitable. Therefore, as a lock used at a construction site, a code-type lock that performs a lock operation by matching codes such as numerals is often used. As a code-type lock, the lock / unlock code is stored in the memory, and based on the comparison between the input code and the unlock / lock code, the actuator or motor is operated to set the lock / unlock state. A switching type electronic lock (for example, Patent Document 1) is known.

In the electronic lock system 10 shown in FIG. 1, only one electronic lock 12, one worker terminal 14, and one administrator terminal 16 are shown, but a plurality of these may be provided. The term “site worker” in this specification is not limited to those who actually work at the construction site where the electronic lock 12 is used, but also those who simply carry in / out materials to the construction site, or It is a concept that includes those who visit and confirm construction sites.

  The electronic lock 12 is one in which at least one of unlocking and locking (hereinafter referred to as “locking operation”) is performed by a field worker. In the present embodiment, the electronic lock 12 is used to lock a partition fence such as a temporary fence provided at the entrance of the construction site. Of course, the electronic lock 12 may be used for other purposes. For example, it may be used to lock a work box installed at a construction site.

  The lock type of the electronic lock 12 may be any type as long as the lock on the lock target can be realized. For example, a padlock type or a dial lock type having a dial part and a wire part may be used.

  The control unit 30 includes, for example, a microcontroller and controls each unit of the electronic lock 12 according to a program stored in the storage unit 34 described later. The control unit 30 also functions as a lock number setting unit 32 as a lock code setting unit according to the program.

  The lock number setting unit 32 sets a lock code for performing the lock operation of the electronic lock 12. The lock code is composed of, for example, numbers, letters, symbols, or combinations thereof. In the present embodiment, the lock code is a lock number composed of 8 digits, but is not limited to this.

  The lock number setting unit 32 sets a lock number including an on-site worker ID for identifying a person who may lock the electronic lock 12, that is, an on-site worker at a construction site where the electronic lock 12 is used. . In the present embodiment, the field worker ID is transmitted from the server 18. In the present embodiment, among the lock numbers composed of 8 digits, the upper 4 digits are the vendor ID, and the lower 4 digits are the numbers selected by the lock number setting unit 32 at random.

  In this embodiment, the unlock number for unlocking the electronic lock 12 and the lock number for locking are the same number. However, the unlock number and the lock number are set to different numbers. May be.

  The storage unit 34 includes, for example, a ROM (Read Only Memory) or a RAM (Randam Access Memory). The storage unit 24 stores a program for operating each unit of the electronic lock 12.

  The storage unit 34 stores the lock number 36 set by the lock number setting unit 32. A plurality of lock numbers 36 may be set and stored. For example, when two lock numbers are set, the lock operation can be performed by any one of the lock numbers.

  Further, the storage unit 34 stores a serial number 38 for uniquely specifying the electronic lock 12. As will be described later, the serial number 38 is transmitted to the server 18 together with various information, so that the server 18 can identify which electronic lock 12 has transmitted the various information. It is done.

  The number input unit 40 includes, for example, a dial unit or a number input button. The number input unit 40 is for a field worker who performs a lock operation on the electronic lock 12 to input an input lock number.

  The locking / unlocking unit 42 includes, for example, an actuator (including a motor or a solenoid) for switching between fixing / releasing of a wire or a shackle that realizes locking of a lock target. The locking / unlocking unit 42 switches the locking / unlocking state of the electronic lock 12 by switching the fixation / release of the wire or shackle according to the instruction command from the control unit 30.

  The communication unit 44 as the electronic lock side transmission unit includes, for example, a LAN adapter or a short-distance communication adapter (Bluetooth (registered trademark) adapter). The communication unit 44 is used for connecting to the communication line 20. The electronic lock 12 may be directly connected to the communication line 20 via the communication unit 44, or communicates with a communication device installed at a construction site by short-range communication, and communicates via the communication device. It may be connected to the line 20. Each information transmitted / received in the communication unit 44 will be described later.

  The configuration of the electronic lock 12 is as described above. Here, an outline of the operation of the electronic lock 12 will be described.

  First, when a vendor ID is received from the server 18, the lock number setting unit 32 sets a lock number 36 including the vendor ID and stores it in the storage unit 34. When the lock number 36 is set, the control unit 30 causes the communication unit 44 to transmit the lock number 36 and the serial number 38 to the server 18. Next, when an input lock number is input by the field worker in the number input unit 40, the control unit 30 reads the input lock number. The control unit 30 compares the read input lock number with the lock number 36 stored in the storage unit 34. As a result of the comparison processing, when both match, the locking / unlocking unit 42 is switched between the locking state and the unlocking state. When the lock state is switched (that is, when the lock operation is performed), the control unit 30 causes the communication unit 44 to store the lock state information as the lock operation information, the input lock number used for the lock operation, and The serial number 38 is transmitted to the server 18. The lock state information indicates that the lock operation has been performed, and at the same time indicates the current lock state (whether it is locked or unlocked). Preferably, the communication unit 44 transmits at least the lock state information to the server 18 when the lock operation is performed on the electronic lock 12, that is, immediately after the lock operation is performed.

  The worker terminal 14 is a terminal used by the field worker as described above, and may be any terminal as long as the functions described below can be realized. For example, it may be a smartphone, a tablet terminal, or a PC (Personal Computer).

  The control unit 50 includes, for example, a microcontroller and controls each unit of the worker terminal 14 according to a program stored in a storage unit (not shown) of the worker terminal 14.

  The communication unit 52 includes, for example, a LAN adapter or a mobile phone line antenna. The communication unit 44 is used for connecting to the communication line 20. In the present embodiment, the communication unit 52 receives the lock number 36 set in the electronic lock 12 from the server 18.

  The display unit 54 includes, for example, a liquid crystal panel. The display unit 54 displays various information. In the present embodiment, the lock number set in the electronic lock 12 is displayed on the display unit 54.

  In addition, the worker terminal 14 is provided with a storage unit including a ROM or a RAM, an input unit including a touch panel or a button, and the like.

  As described above, the manager terminal 16 is a terminal used by a construction site where the electronic lock 12 is used or a manager of the site worker. Since the configuration outline of the administrator terminal 16 is the same as that of the worker terminal 14, the description thereof is omitted.

  The server 18 is composed of a computer having a performance that can realize the functions described below. The server 18 is for managing one or a plurality of electronic locks 12 used at one or a plurality of construction sites. Further, the server 18 is for managing an operator (on-site worker) who performed a lock operation on the electronic lock 12 and an operation time.

  The control unit 60 includes, for example, a microcontroller and controls each unit of the server 18 according to a program stored in a storage unit 66 described later.

  The timer 62 includes, for example, a timer IC, a crystal resonator, a clock module, and the like. The timer 62 measures the current time (including date) and outputs it to the controller 60.

  The communication unit 64 as the server side transmission unit includes, for example, a LAN adapter. The communication unit 64 is used to connect to the communication line 20. In the present embodiment, the communication unit 64 transmits and receives various types of information to and from the electronic lock 12, the worker terminal 14, and the administrator terminal 16.

  The storage unit 66 as a server-side storage unit includes a ROM, a RAM, a hard disk, or the like. The storage unit 66 stores a program for operating each unit of the server 18.

  The storage unit 66 stores various DBs (databases). In the present embodiment, the storage unit 66 stores an operator DB 70, a work schedule DB 72, a lock number DB 74, and a lock operation history DB 76. Hereinafter, each DB will be described with reference to FIGS.

  The worker DB 70 has one or more construction sites where one or more electronic locks 12 are used, that is, a site worker who may perform a locking operation on one or more electronic locks 12 managed by the server 18. The information of the field worker who performs work etc. is memorized. For example, the name of the field worker, the field worker ID, and the contact information are associated and stored. The above information is registered in the worker DB 70 by a manager or a field worker. For example, the manager accesses the server 18 from the manager terminal 16 and the manager registers information on the site worker.

  An example of the data structure of the worker DB 70 is shown in FIG. In the present embodiment, in the worker DB 70, the name of the field worker, the name of the contractor to which the field worker belongs, the contractor ID as the field worker ID for identifying the field worker, and the contact information of the field worker As a registered email address. In the present embodiment, a trader ID for identifying a field worker in a trader unit is used as the field worker ID. For example, “A Taro” and “A Taro” belong to the same contractor “A field construction”, and therefore the same contractor ID “1234” is associated with both. In addition, as field worker ID, it replaces with trader ID and the personal ID identified per field worker may be used.

  The work schedule DB 72 stores information indicating work schedules (work schedules) of one or more construction sites where the one or more electronic locks 12 managed by the server 18 are used. For example, the name of the construction site, the serial number 38 of the electronic lock 12 used at the construction site, the construction date, the contractor ID indicating the planned work contractor, and the like are associated and stored. Similar to the worker DB 70, the above information is registered in the work schedule DB 72 by a manager or a field worker. For example, the administrator accesses the server 18 from the administrator terminal 16, and the administrator registers information indicating the work schedule.

  FIG. 3 shows an example of the data structure of the work schedule DB 72. In this embodiment, in the work schedule DB 72, a work site ID for uniquely identifying a construction site, a construction site name, a serial number 38 of the electronic lock 12 used at the construction site, a construction date, and a contractor scheduled to perform the construction work. Is associated and registered.

  The lock number DB 74 stores the serial number 38 of one or more electronic locks 12 managed by the server 18 and the lock number set for the electronic lock 12 in association with each other. As described above, when the lock number 36 is set by the lock number setting unit 32 of the electronic lock 12, the lock number 36 and the serial number 38 of the electronic lock 12 are transmitted from the electronic lock 12 to the server 18. The control unit 60 registers these pieces of information received from the electronic lock 12 in the lock number DB 74.

  FIG. 4 shows an example of the data structure of the lock number DB 74. As described above, a plurality of lock numbers may be associated with one electronic lock 12 (that is, one serial number 38). For example, the electronic lock 12 whose serial number 38 is “B0001” is associated with “123-6048” and “5768-9940” as lock numbers. That is, for the electronic lock 12 whose serial number 38 is “B0001”, the lock operation is enabled when either “123-6048” or “5768-9940” is input as the input lock number. When the unlock number and the lock number are set separately, the serial number 38, the unlock number, and the lock number are associated in the lock number DB 74.

  The lock operation history DB 76 stores lock operation history information, which is a lock operation history for one or more electronic locks 12 managed by the server 18. At least the serial number 38 of the electronic lock 12, the field worker who unlocked the electronic lock 12, the field worker who locked the electronic lock 12, and the like are associated and stored. Preferably, information indicating the time at which the server 18 receives the lock state information is further associated and stored. As described above, when a lock operation is performed on the electronic lock 12, the lock state information, the lock number 36, and the serial number 38 of the electronic lock 12 are transmitted from the electronic lock 12 to the server 18. The control unit 60 registers various information in the lock operation history DB 76 based on the information received from the electronic lock 12.

  FIG. 5 shows an example of the data structure of the lock operation history DB 76. In the present embodiment, in the lock operation history DB 76, the serial number 38 of the electronic lock 12, the site ID for uniquely identifying the construction site where the electronic lock 12 is used, the name of the construction site, and the date when the lock operation was performed. The unlocking time when the unlocking operation was performed, the vendor ID for identifying the site worker who performed the unlocking operation, the name of the site worker who performed the unlocking operation, the locking time when the locking operation was performed, and the locking operation The trader ID for identifying the performed field worker and the name of the field worker who performed the locking operation are registered in association with each other.

  The control unit 60 registers each piece of information in the lock operation history DB 76 based on various information transmitted from the electronic lock 12. Details of the registration process of the lock operation history DB 76 will be described later.

  Hereinafter, the flow of processing in the electronic lock system 10 will be described with reference to the flowchart shown in FIG. At the start of the flowchart shown in FIG. 6, it is assumed that the electronic lock 12 is in a state where a partition fence at the construction site is locked, and the storage unit 66 of the server 18 stores the worker DB 70 shown in FIG. It is assumed that the work schedule DB 72 shown in FIG.

  In step S <b> 10, the control unit 60 of the server 18 refers to the work schedule DB 72 and plans to perform the work on the construction site for the electronic lock 12 used at the construction site where the work is scheduled for today. A trader ID indicating the trader is transmitted. For example, if today is “June 27”, the control unit 60 refers to the work schedule DB 72 shown in FIG. 3 and the electronic lock 12 (used in “Yamada House (site ID: A0001)”) ( The vendor IDs “1234” and “5768” are transmitted to the serial number: B0001. At the same time, the vendor ID “1487” is transmitted to the electronic lock 12 (serial number: B0002), and the vendor ID “9987” is transmitted to the electronic lock 12 (serial number: B0003). In the present embodiment, the supplier ID transmission process in step S10 is executed every day before the work at the construction site is started (early morning, etc.). Hereinafter, the processing of the electronic lock 12 with the serial number “B0001” will be described.

  In step S12, the lock number setting unit 32 of the electronic lock 12 sets the lock number 36 including the transmitted supplier ID. In this example, since two vendor IDs are transmitted in step S10, the lock number setting unit 32 sets two lock numbers 36. The two lock numbers 36 correspond to each supplier. Here, the lock number 36 includes the supplier ID “1234”, that is, the lock number “1234-6048” corresponding to the supplier “A field construction”, and the lock number “5768-” corresponding to the supplier “B mountain construction”. 9940 "is set. The two set lock numbers 36 are stored in the storage unit 34.

  In step S <b> 14, the electronic lock 12 transmits the two lock numbers 36 and the serial number 38 set in step S <b> 12 to the server 18.

  In step S16, the server 18 that has received the lock number 36 and the serial number 38 registers them in the lock number DB 74 (see FIG. 4).

  In step S18, the control unit 60 of the server 18 searches the worker DB 70 using the supplier ID included in the lock number 36 registered in the lock number DB 74 as a key, and contacts (email addresses) associated with the supplier ID. ). In this example, the mail addresses of the field workers “A Taro” and “A Taro” are specified using the vendor ID “1234” as a key. Further, the mail address of the field worker “B Yamasaburo” is specified using the vendor ID “5768” as a key.

  The server 18 transmits the lock number 36 set in the electronic lock 12 to the identified contact (that is, the worker terminal 14). As a result, the lock number 36 is displayed on the display unit 54 of the worker terminal 14 used by “Taro Ada”, “Jiro Ada”, and “B Saburo B”. The lock number for performing the lock operation on can be grasped.

  Here, the server 18 transmits only the lock number “1234-6048” including the supplier ID to “A Taro” and “A Taro” corresponding to the supplier ID “1234”, and the supplier ID “5768”. "B Yamasaburo" corresponding to "", only the lock number "5768-9940" including the supplier ID is transmitted. As a result, the lock number “1234-6048” including the supplier ID “1234” can be known only by the field workers (“Taro Ada” and “Taro Ada”) identified by the supplier ID. The lock number “5768-9940” including the trader ID “5768” is known only to the field worker (“B Yamasaburo”) identified by the trader ID.

  In step S20, the control unit 30 of the electronic lock 12 determines whether or not the unlocking operation has been performed by the field worker. Specifically, it is determined whether the input lock number input in the number input unit 40 matches one of the two lock numbers 36 stored in the storage unit 34. The electronic lock 12 stands by until an unlocking operation is performed, and when it is determined that the unlocking operation has been performed, the process proceeds to step S22. Here, it is assumed that “Ada Taro” inputs the input lock number “1234-6048” and performs the unlocking operation.

  When the unlocking operation is performed in step S20, the electronic lock 12 immediately, in step S22, the lock state information indicating the unlocked state, the input lock number “1234-6048” input in the unlocking operation, and the serial number 38. Is transmitted to the server 18.

  In step S24, the control unit 60 of the server 18 registers various information in the lock operation history DB 76 based on the information transmitted from the electronic lock 12 in step S22. Hereinafter, the registration process for the lock operation history DB 76 will be described in detail.

  First, the control unit 60 registers the received serial number 38 in the lock operation history DB 76. Next, referring to the work schedule DB 72 (FIG. 3), the site ID and construction site name are identified from the received serial number 38, and the identified site ID and construction site name are registered in the lock operation history DB 76.

  In addition, the control unit 60 acquires the time sent from the time measuring unit 62 when the lock state information is received from the electronic lock 12. In this embodiment, since the lock state information indicating the unlocked state is transmitted to the server 18 immediately after the unlocking operation is performed, the time when the lock state information indicating the unlocked state is received is set to the unlocking state of the electronic lock 12. It can be regarded as the lock time. Further, as described above, in the present embodiment, the electronic lock 12 is used to lock the partition wall at the construction site, and therefore, the work at the site where the electronic lock 12 is unlocked at the time when the electronic lock 12 is unlocked. It is assumed that it is the time when the worker enters the construction site (construction start time). The control unit 60 registers the date and the unlocking time (entry time) specified in this way in the lock operation history DB 76.

  In addition, the control unit 60 acquires a vendor ID included in the input lock number “1234-6048” input in the unlocking operation. In the present embodiment, “1234” that is the first four digits of the input lock number “1234-6048” is acquired as the supplier ID. Further, the control unit 60 searches the worker DB 70 (FIG. 2) using the acquired supplier ID “1234” as a key, and specifies the supplier name “A field construction” associated with the supplier ID “1234”. Then, the acquired trader ID and trader name are registered in the lock operation history DB 76 (see the first record in FIG. 5).

  In step S <b> 26, the server 18 transmits various information registered in the lock operation history DB 76 in step S <b> 24 to the administrator terminal 16. The server 18 may transmit all information registered in the lock operation history DB 76. In this example, the server 18 transmits information indicating the site name, date, unlocking time (entry time), and unlocking company. . Thereby, these pieces of information are displayed on the display unit (not shown) of the administrator terminal 16.

  The following steps S28 to S34 are processing when the electronic lock 12 is locked. Basically, the flow of processing is the same as the processing from steps S20 to S26, which is processing when unlocked.

  In step S28, the control unit 30 of the electronic lock 12 determines whether or not a locking operation has been performed by a site worker. Specifically, it is determined whether the input lock number input in the number input unit 40 matches one of the two lock numbers 36 stored in the storage unit 34. The electronic lock 12 waits until the locking operation is performed. If it is determined that the electronic lock 12 is locked, the process proceeds to step S30. Here, it is assumed that “B Yamasaburo” inputs the input lock number “5768-9940” and performs the locking operation.

  When the locking operation is performed in step S28, the electronic lock 12 immediately receives the lock state information indicating the locking state, the input lock number “5768-9940” input in the locking operation, and the serial number 38 in step S30. Send to.

  In step S32, the control unit 60 of the server 18 registers various types of information in the lock operation history DB 76 based on the information transmitted from the electronic lock 12 in step S30.

  First, the control unit 60 registers the received serial number 38 in the lock operation history DB 76. Next, referring to the work schedule DB 72 (FIG. 3), the site ID and construction site name are identified from the received serial number 38, and the identified site ID and construction site name are registered in the lock operation history DB 76. In addition, when the record regarding the set of the received serial number 38 and the date acquired from the timing unit 62 is already registered in the lock operation history DB 76, the following information is registered in the form added to the record. Also good.

  The control unit 60 acquires the time sent from the time measuring unit 62 when the lock state information is received from the electronic lock 12. In this embodiment, since the lock state information indicating the lock state is transmitted to the server 18 immediately after the lock operation is performed, the time when the lock state information indicating the lock state is received is regarded as the lock time of the electronic lock 12. be able to. Further, as described above, in the present embodiment, the electronic lock 12 is used to lock the partition bar at the construction site. Therefore, the worker at the site who locked the electronic lock 12 at the time when the electronic lock 12 was locked was used. It is assumed that it is the time of leaving the construction site (the construction end time). The control unit 60 registers the date and the lock time (exit time) thus specified in the lock operation history DB 76.

  In addition, the control unit 60 acquires the supplier ID included in the input lock number “5768-9940” input in the locking operation. In the present embodiment, “5768”, which is the first four digits of the input lock number “5768-9940”, is acquired as the supplier ID. Further, the control unit 60 searches the worker DB 70 (FIG. 2) using the acquired supplier ID “5768” as a key, and specifies the supplier name “B mountain construction” associated with the supplier ID “5768”. Then, the acquired trader ID and trader name are registered in the lock operation history DB 76 (see the first record in FIG. 5).

  In step S <b> 34, the server 18 transmits various information registered in the lock operation history DB 76 in step S <b> 32 to the administrator terminal 16. In this example, information indicating the site name, date, locking time (exit time), and locking company is transmitted. Thereby, these pieces of information are displayed on the display unit of the administrator terminal 16.

  As described above, in the electronic lock system 10, the lock number setting unit 32 of the electronic lock 12 sets the lock number 36 including a supplier ID for identifying the field worker. The set lock number 36 is disclosed only to the trader indicated by the trader ID included therein, and only the trader knows it. After that, when the input lock number is input to the electronic lock 12 and the lock operation is performed, the input lock number is transmitted to the server 18. Since the input lock number includes a trader ID indicating the trader who performed the lock operation, the trader who performed the lock operation can be identified based on the trader ID acquired from the input lock number. The lock operation history information including the supplier ID indicating the supplier who performed the lock operation is transmitted from the server 18 to the administrator terminal 16, so that the administrator operates the electronic lock 12 with respect to the electronic lock 12 while being remote from the construction site. It is possible to know what has been done and who has operated the lock.

  In the electronic lock system 10, the lock state information is transmitted to the server 18 when the lock operation is performed. Therefore, it can be assumed that the time when the server 18 receives the lock state information is the time when the lock operation is performed on the electronic lock 12. In the lock operation history DB 76, the operation time when the lock operation is performed is also registered in association with the supplier who performed the lock operation. Thereby, the administrator can grasp not only the trader who performed the lock operation on the electronic lock, but also the operation time. For example, as in the present embodiment, if the electronic lock 12 locks a partition bar provided at the entrance of the construction site, the operation time is used as the entrance time and the exit time of the contractor's construction site. Is possible.

  Furthermore, according to the electronic lock system 10, the lock number 36 set by the lock number setting unit 32 includes a lower four-digit number set at random. Thereby, the lock number 36 of the electronic lock 12 differs for each construction site. Further, if the lock number setting unit 32 updates and sets the lock number every day (that is, the lock number 36 is updated intermittently), the lock number varies from day to day. Furthermore, the lock number 36 is notified only to the field worker registered in the server 18 (worker DB 70). These characteristics make it more difficult for a person who should not unlock the electronic lock 12, such as an outsider, to unlock the electronic lock 12. That is, an improvement in the security level of the electronic lock 12 can be expected.

  As mentioned above, although embodiment which concerns on this invention was described, this invention is not limited to the said embodiment, A various change is possible unless it deviates from the meaning of this invention.

  For example, the lock number setting unit 32 of the electronic lock 12 may set (that is, update) the lock number 36 a plurality of times within one day. For example, the lock number setting unit 32 executes update processing for updating the lock number 36 every hour, every three hours, every six hours, or the like. In this case, the vendor ID transmitted from the server 18 is held in the storage unit 34 of the electronic lock 12 before the work on the construction site is started, and the lock number 36 including the held vendor ID is re-used for the day. Set. Each time the lock number 36 is updated, the updated lock number 36 and serial number 38 are transmitted from the electronic lock 12 to the server 18, and the lock number 36 is transmitted from the server 18 to the worker terminal 14. By intermittently updating the lock number 36, the security level of the electronic lock 12 can be further improved.

  In the electronic lock system 10, the server 18 has acquired the lock operation history of one or a plurality of electronic locks 12. From the viewpoint of acquiring the lock operation history of one electronic lock 12, the electronic lock 12 can be obtained. Can be operated stand-alone. In this case, the worker DB 70, the work schedule DB 72 (of which at least the date and the planned work supplier ID), and the lock operation history DB 76 (of which at least the date, the unlock time, the unlocker ID, the lock time, and the locker ID) are electronic. It is stored in the storage unit 34 as a lock side storage unit. In addition, the electronic lock 12 is provided with a time measuring unit for measuring the current time.

  When the electronic lock 12 operates in a stand-alone manner, information indicating the lock number 36 is transmitted from the communication unit 44 to the operator terminal 14 when the lock number setting unit 32 sets the lock number 36. And if an input lock number is input into the number input part 40 by a field worker and a lock operation is carried out, the control part 30 will acquire trader ID from an input lock number, and will carry out lock operation log information including the said trader ID. Register in the lock operation history DB 76 stored in the storage unit 34. Preferably, the control unit 30 acquires an operation time when the lock operation is performed, and registers the operation ID and the operation time in the lock operation history DB 76 in association with each other. When the lock operation history information is registered in the lock operation history DB 76, the registered lock operation history information is transmitted from the communication unit 44 of the electronic lock 12 to the administrator terminal 16.
