Description

  The present invention relates to an electric lock system and a building including the same.

  Conventionally, door bodies such as an entrance door provided with an electric lock for electrically locking and unlocking a lock are known. This door has an advantage in that the electric lock can be remotely operated by an electronic key possessed by the user.

  However, even a door body provided with an electric lock in this way is conventionally provided with a locking / unlocking device that mechanically locks and unlocks the lock (see, for example, Patent Document 1). In this mechanical locking / unlocking device, a key is inserted into a key hole of the device to perform locking / unlocking.

The reason why the mechanical locking / unlocking device is also used in this way is that it can cope with a case different from the normal use in which the electric lock is locked / unlocked by the electronic key. For example, since a building is under construction, even if a door is installed in the building in a state where power from a commercial AC power source is not supplied, the electric lock of the door cannot be used. For this reason, in the case of building construction, if the door body is locked using the mechanical locking / unlocking device, it is possible to cope with a state where the electric lock cannot be used.
JP-A-8-184228

  However, the door body having the above-described conventional mechanical locking / unlocking device always has a risk of being unlocked illegally by picking or the like.

  Therefore, as one measure for preventing unauthorized unlocking due to picking or the like, it is conceivable to completely eliminate the mechanical locking / unlocking device from the door body. In this way, the door body has no keyhole, so that unauthorized unlocking due to picking or the like can be prevented.

  However, on the other hand, if the mechanical locking / unlocking device is lost, another problem will arise. In other words, if it becomes impossible to supply power to the electric lock from the normally used power supply system, the electric lock cannot be locked or unlocked at all. As an example of such a case, a case where a building is under construction can be considered. In this case, since the power source is not supplied from the commercial AC power source that is supplied during normal use, the electric lock cannot be locked or unlocked at all.

  The present invention has been made in view of such problems, and it is not necessary to provide a mechanical locking / unlocking device as a countermeasure against the inability to supply power from a normally used power supply system. The main object is to provide an electric lock system capable of preventing the release and a building equipped with the same.

  The present invention employs the following means in order to solve the above problems.

  That is, in the first invention, the identification information provided to the door body that opens and closes the opening to be attached, and the electric lock that electrically locks and unlocks the lock, and the unique identification information for remotely operating the lock and unlock of the electric lock. An electronic key that wirelessly transmits the identification information, and a control unit that compares the identification information wirelessly received from the electronic key with previously registered identification information and locks and unlocks the electric lock when the two information matches. In this electronic lock system, a plurality of power supply systems are provided, and power is supplied to the electric lock from any one of the power supply systems.

  According to the first aspect of the present invention, even when power cannot be supplied to the electric lock from one normally used power supply system, power can be supplied to the electric lock using another power supply system. It becomes. For this reason, even if there is no mechanical locking / unlocking device, locking / unlocking does not become impossible. Therefore, there is no need to provide a mechanical locking / unlocking device as a countermeasure against the inability to supply power from a normally used power supply system, and unauthorized release due to picking or the like can be prevented.

  In a second invention, in the first invention, the plurality of power supply systems preferably include an AC power supply system using a commercial AC power supply as a source and a DC power supply system using a DC power supply as a source.

  If the AC power supply system is a normal power supply system, power may not be supplied from the AC power supply system due to, for example, building construction or power outage. In such a case, since it is possible to supply power from the DC power supply system, the electric lock can be locked and unlocked by the electronic key even when power is not supplied from the AC power supply system. For this reason, it is not necessary to provide a mechanical locking / unlocking device as a countermeasure against power being not supplied from the AC power supply system.

  In the second aspect of the invention, the door body opens and closes an opening that communicates indoors and outdoors of the building, and the DC power supply system includes a power supply connection portion that can be connected to a DC power source on the outdoor side of the door body. It is preferable to have.

  In a door body that opens and closes an opening that communicates indoors and outdoors of a building, remote control of an electric lock by an electronic key is performed on the outdoor side of the door body. For this reason, in the structure connected to the DC power supply on the indoor side of the door body, the connection between the DC power supply and the power supply connecting portion cannot be canceled after the electric lock is locked. In that respect, if the power supply connection portion can be connected to the DC power supply on the outdoor side of the door body, the connection between the DC power supply and the power supply connection portion can be eliminated even after locking with an electric lock. By doing so, the consumption of the DC power supply can be suppressed.

  In the second invention, the electronic key includes a plurality of keys to which identification information different from each other is assigned, the identification information of each key is associated with the plurality of power supply systems, and the control means includes It is preferable to determine which one of the plurality of power supply systems is supplied with power, and use identification information corresponding to the determined power supply system for verification.

  According to the present invention, if the power supply system for supplying power to the electric lock is different, the identification information used for verification by the control means is different, and the electronic key that can be used to lock and unlock the electric lock is also different. This makes it possible to use different electronic keys depending on the power supply system, such as a normal key and an emergency key.

  Furthermore, in the second invention, the electronic key includes a primary key and a temporary key to which different identification information is given, power is not supplied from the AC power supply system to the electric lock, and the DC When power is supplied from the power supply system to the electric lock, it is preferable that the control means uses the pre-registered identification information of the temporary key for verification.

  As a result, when power is not supplied from the AC power supply system and a temporary key different from the primary key is required for construction personnel, for example, during construction of a building, a DC power supply is supplied to the electric lock. If power is supplied from the system, the electric lock can be locked and unlocked by the temporary key. For this reason, it is not necessary to provide a mechanical locking / unlocking device as a countermeasure for locking / unlocking with a temporary key.

  In this case, when power is supplied to the electric lock from the AC power supply system, the control means is preferably invalidated by deleting the identification information of the temporary key registered in advance. As a result, when power is supplied from the AC power supply system, it is only possible to lock and unlock the electric lock with the primary key, and it becomes impossible to lock and unlock the electric lock with the temporary key. Release can be prevented.

  Furthermore, it is preferable that the control means invalidates the temporary key identification information after a predetermined time has elapsed after power supply from the AC power supply system. As a result, it is possible to lock and unlock the electric lock with the temporary key until a predetermined time elapses after the power from the AC power supply system is supplied. For this reason, for example, a temporary key can be used for treatments required after power is supplied from the AC power supply system, such as final finishing processing before delivery after completion of building construction.

  Note that any one of the electric lock systems is preferably provided in a building.

  Below, the entrance door which is one embodiment is demonstrated, referring drawings.

It has become. The door frame 13 is provided with a locking hole (not shown), and the locking member 32 of the electric lock 22 advances and retreats toward the locking hole to lock and unlock the electric lock 22. When the electric lock 22 is locked, it becomes impossible to open the door body 12 in the state where the opening is closed. On the other hand, when the electric lock 22 is unlocked, the door body 12 is opened and the door frame 13 is opened. The opening can be opened.

  The entrance door 11 includes an energizing member 41. The energizing member 41 is provided on the upper side on which the hinge 36 is provided. The energization member 41 is for supplying power between the door body 12 and the door frame 13 so as to supply power from the door frame 13 side to the electric lock 22 and the controller 24 provided on the door body 12.

  Similarly to the door side member 42, the frame side member 43 includes a flat plate portion 61 and a wiring storage portion 64. The flat plate portion 61 is provided with a through hole 62 through which the fastening member T is inserted when the frame side member 43 is attached to the door frame 13 and a wiring insertion hole 63. The wiring storage part 64 is provided on the attachment side of the flat plate part 61 to the door frame 13, and its upper part is open.

  Of the pair of energization wires 44, 45, the first energization wire 44 constitutes a part of an AC power supply system using the commercial AC power supply AC as a source, and the second energization wire 45 is a DC power supply system using the DC power supply DC as a source. Part of A door-side connection portion 71 is provided at one end of the first energization wiring 44, and the door-side connection portion 71 is drawn out above the wiring storage portion 54 of the door-side member 42. Further, a power connection portion 72 is provided at the other end portion of the first energization wiring 44, and the power connection portion 72 reaches the wiring storage portion 64 of the frame side member 43 through the wiring insertion holes 53 and 63, and above it. Has been drawn to. On the other hand, a door-side connection portion 73 is provided at one end of the second energization wiring 45, and the door-side connection portion 73 is drawn above the wiring storage portion 54 of the door-side member 42. In addition, a power connection portion 74 is provided at the other end of the second energization wiring 45, and the power connection portion 74 extends from the gap 14 between the door side member 42 and the frame side member 43 through the wiring insertion hole 53. Has been pulled out.

  In the energizing member 41 configured as described above, the door-side member 42 is attached to the door body 12 and the frame-side member 43 is attached to the door frame 13 with the door body 12 attached to the door frame 13. . In this case, the wiring accommodating portions 54 and 64 are accommodated in the accommodating holes 81 and 82 provided in the door main body 12 and the door frame 13, and in this state, provided in the upper and lower sides of the through holes 52 and 62 and the accommodating holes 81 and 82. The mounting holes 83 and 84 are used to attach the fastening member T.

  Here, in the door main body 12, a pair of internal wirings 91 and 92 whose one ends are connected to the controller 24 are provided. The first internal wiring 91 constitutes a part of the AC power supply system, and the second internal wiring 92 constitutes a part of the DC power supply system.

  The door side connection portion 71 of the first energization wiring 44 is connected to the connection portion 93 of the first internal wiring 91. The power supply connection portion 72 is connected to the connection portion 97 of the first power supply wiring 96. The first power supply wiring 96 is connected to the commercial AC power supply AC via the power supply circuit 111. On the other hand, the door side connection portion 73 of the second energization wiring 45 is connected to the connection portion 94 of the second internal wiring 92. The power supply connection portion 74 can be connected to the connection portion 99 of the second power supply wiring 98. The second power supply wiring 98 is connected to a DC power supply DC such as a battery.

  When the construction of the building is completed, power is supplied from a commercial AC power supply AC. Accordingly, the commercial AC power supply AC, the power supply circuit 111, the first power supply wiring 96, the first energization wiring 44, and the first internal wiring 91 become an AC power supply system, and the electric lock 22 and the controller of the door body 12 are connected through the AC power supply system. Power is supplied to 24.

  On the other hand, when the building is still under construction, the power supply connection portion 74 is connected to the connection portion 99 of the second power supply wiring 98 with the start of construction every day. As a result, during building construction, the DC power supply DC, the second power supply wiring 98, the second energization wiring 45, and the second internal wiring 92 become a DC power supply system, through which the electric lock 22 and the controller of the door body 12 are connected. Power is supplied to 24.

  Next, an electric lock system, that is, a control system for controlling locking / unlocking of the electric lock 22 by the controller 24 will be described with reference to FIG. FIG. 4 is a block diagram showing an outline of the present control system.

  As shown in FIG. 4, the present control system mainly includes the controller 24 and electric lock 22 provided on the door body 12 and an electronic key K. The controller 24 is configured by a known microcomputer including a CPU 101, a memory 102, and the like. The memory 102 stores in advance a control program for executing this control system, and stores identification information received from the electronic key K.

  The controller 24 is connected to the wireless communication unit 103 and the energization member 41. The wireless communication unit 103 is provided in the verification unit 23, and the wireless communication unit 103 enables the controller 24 to perform wireless communication with an external device. The energizing member 41 is connected to the first power supply wiring 96 and can be connected to the second power supply wiring 98. When power is supplied from the commercial AC power supply AC, the controller 24 is supplied with power through the AC power supply system. When the power connection unit 74 is connected to the second power supply wiring 98, power is supplied to the controller 24 through a DC power supply system.

  The electric lock 22 is connected to the controller 24. For this reason, when power is supplied to the controller 24 from the AC power supply system, the power is supplied to the electric lock 22 through the controller 24. Further, when power is supplied to the controller 24 from the DC power supply system, the power is supplied to the electric lock 22 through the controller 24. The controller 24 transmits a control signal to the electric lock 22, and the electric lock 22 locks and unlocks the lock based on the control signal.

  The electronic key K is composed of a primary key K1 possessed by the user and a construction temporary key K2 possessed by a construction person. Each of the keys K1 and K2 includes a wireless communication unit m1, and a distance of about several meters (for example, 1 to 2 m) or several centimeters (for example, 1 to 2 cm) is used as a transmission / reception area, Wireless communication is possible. Each key K1, K2 is provided with a memory m2, and individual identification information different for each key K1, K2 is stored in the memory m2. Among these, in the memory m2 of the temporary key K2, in addition to the identification information of the temporary key K2, the identification information of the primary key K1 corresponding to the temporary key K2 is stored in association with the identification information of the temporary key K2.

  Each key K1, K2 is provided with an input member m3 having a registration button, a lock button, an unlock button, and the like. The user operates a registration button when registering identification information in the controller 24, a lock button when the electric lock 22 is locked, and an unlock button when the electric lock 22 is unlocked. . The registration button is provided only on the temporary key K2.

  In the electric lock system configured as described above, a request signal is transmitted from the controller 24 based on the button operation of each key K1, K2 in the transmission / reception area between each key K1, K2 and the controller 24. Each key K1, K2 transmits identification information in response to the request signal. In this case, the temporary key K2 transmits not only the identification information of the temporary key K2 but also the identification information of the corresponding primary key K1. The controller 24 receives the identification information from the keys K1 and K2, and executes identification information registration and authentication processing based on the identification information. Each key K1, K2 transmits a control signal corresponding to the operation to the controller 24 based on the button operation of the input member m3. The controller 24 receives the control signal and executes control according to the button operation.

  Next, the controller 24 determines whether power is supplied to the controller 24 from the AC power supply system or the DC power supply system by the internal circuit. Therefore, the internal circuit will be described with reference to FIG. FIG. 5 is a circuit diagram showing an internal circuit, and shows a state where both the AC power source AC and the DC power source DC are connected for convenience. However, in practice, only the DC power source DC is connected during construction of the building, and only the commercial AC power source AC is connected after completion of construction of the building.

  When power is supplied from the AC power supply system (specifically, when power is supplied from the commercial AC power supply AC), the DC voltage output from the switching power supply circuit 111 is input to the voltage detection circuit 112. It has become. The first output side of the voltage detection circuit 112 is connected to the base of the first transistor TR1. The collector of the first transistor TR1 is connected to the CPU 101, and the emitter is grounded.

  The first output side of the voltage detection circuit 112 is connected to the activation circuit 113. The output side of the start circuit 113 is connected to the base of the second transistor TR2 for driving the relay. When a DC voltage is supplied from the voltage detection circuit 112, the start circuit 113 causes the second transistor TR2 to be connected. Turned off. The collector of the second transistor TR2 is connected to one end of the drive coil 121 of the relay 114. When the second transistor TR2 is in the off state, the drive coil 121 is in a non-energized state, and the relay switch 122 is connected to the left terminal 123 shown in the figure. Turn on. The left terminal 123 of the relay switch 122 is connected to the second output side of the voltage detection circuit 112. For this reason, the DC voltage output from the second output side is supplied to the relay 114 and output from the relay 114. The output side of the relay 114 is connected to the collector of the first transistor TR1 through a resistor 131. Further, the output side of the relay 114 is connected to the electric lock 22, whereby a DC voltage is supplied to the electric lock 22.

  On the other hand, when power is supplied from the DC power supply system (specifically, when the power supply connecting portion 74 is connected to the second power supply wiring 98), the negative side of the DC power supply DC is grounded. The plus side of the DC power source DC is connected to the starter circuit 113, one end of the drive coil 121 of the relay 114, and the right terminal 124 of the relay 114. When the DC voltage from the DC power source DC is supplied to the startup circuit 113, the startup circuit 113 turns on the second transistor TR2. As a result, the drive coil 121 is energized, and the relay switch 122 is turned on to the right terminal 124. Since the right terminal 124 of the relay switch 122 is connected to the positive side of the DC power source DC, a DC voltage is supplied to the relay 114 and output from the relay 114. This DC voltage is supplied to the collector side of the first transistor TR1 and the electric lock 22.

  As described above, when power is supplied from the AC power supply system, the DC voltage output from the switching power supply circuit 111 is supplied to the electric lock 22 via the relay 114. Further, the first transistor TR1 is turned on by the DC voltage, and the DC voltage is not supplied to the CPU 101, so the input to the CPU 101 is Low. Thereby, the controller 24 recognizes that power is supplied from the AC power supply system.

  On the other hand, when power is supplied from the DC power supply system, a DC voltage is supplied to the electric lock 22 via the relay 114. Further, since no DC voltage is output from the switching power supply circuit 111, the first transistor TR1 is turned off, and the DC voltage output from the relay 114 is supplied to the CPU 101 via the resistor 131. Thereby, the input to the CPU 101 becomes Hi, and the controller 24 recognizes that power is supplied from the DC power supply system.

  Next, a flow for controlling locking / unlocking of the electric lock 22 will be described. This control has three processes: a user registration process for the electronic keys K1, K2, a locking / unlocking process for locking / unlocking the electric lock 22 with the electronic keys K1, K2, and an identification information deleting process for the temporary key K2.

  First, user registration processing of the electronic keys K1 and K2, which is the first processing, will be described based on the flowchart of FIG. This user registration process is executed only once as an initial setting when the entrance door 11 is installed in a building and power is first supplied from the DC power supply system.

  As shown in FIG. 6, in step S11, it is determined whether or not the registration button of the temporary key K2 is operated. If the registration button is not operated, the determination is denied, and the determination is repeated until the registration button is operated.

  Then, when the registration button is operated by the user, the determination is affirmed and the process proceeds to step S12 to execute a process for shifting to the registration mode. In subsequent step S13, a request signal transmission process is executed. In step S14, it is determined whether or not identification information has been received in response to the request signal. When there is no response, that is, when the identification information is not received, the transmission of the request signal is continued until the identification signal is received.

  If there is a response, that is, if identification information is received from the temporary key K2, the process proceeds to step S15, and user registration processing is executed based on the received identification information. In the user registration process, the identification information received from the temporary key K2 is stored in the memory 102 of the controller 24. In this case, since the identification information of the primary key K1 is transmitted from the temporary key K2 in addition to the identification information of the temporary key K2, the identification information of both the temporary key K2 and the primary key K1 is stored in the memory 102.

  Thereafter, in step S16, it is determined again whether or not the registration button is operated. If the registration button is not operated, the determination is denied, and the determination is repeated until the registration button is operated. Then, when the registration button is operated again by the user, the determination is affirmed and the process proceeds to step S17 to end the registration mode.

  Next, the locking / unlocking process of the electric lock 22 as the second process will be described based on the flowchart of FIG. This process is a process of locking and unlocking the electric lock 22 with the electronic keys K1 and K2 after executing the user registration process, and is executed by the controller 24 at a predetermined time period. Note that the flow of control processing is the same regardless of which of the lock buttons and the unlock buttons of the keys K1 and K2 is operated, and therefore, description will be made based on a common flowchart.

  As shown in FIG. 7, in step S21, it is determined whether or not the lock button or the unlock button of the electronic key (primary key K1 or temporary key K2) has been operated. If none of the buttons are operated, the determination is denied and the process is terminated.

  On the other hand, when the lock button or the unlock button is operated by the user, the determination is affirmed and the process proceeds to step S22. In step S22, a request signal transmission process is executed, and in a subsequent step S23, it is determined whether or not identification information has been received in response to the request signal. If there is no response, that is, if no identification information has been received, this process is terminated.

  If there is a response, that is, if identification information is received from the electronic keys K1 and K2, the process proceeds to step S24, and user authentication processing is executed based on the received identification information. In the user authentication process, the received identification information is compared with the identification information stored in the memory 102 in the above-described user registration process, and if both match, it is determined that the authentication is OK.

  Here, when the building is under construction, power is supplied to the controller 24 from the DC power supply system, and the controller 24 recognizes the state. In the user authentication process in this case, both the identification information of the primary key K1 and the identification information of the temporary key K2 are read from the memory 102 and used to collate with the received identification information. For this reason, even if either the primary key K1 or the temporary key K2 is used, if the identification information matches the identification information of the registered primary key K1 or temporary key K2, it is determined that the authentication is OK.

  On the other hand, when the construction of the building is completed and power is supplied to the controller 24 from the AC power supply system, the controller 24 recognizes the state. In the user authentication process in this case, only the identification information of the primary key K1 is read from the memory 102 and used to collate with the received identification information. Therefore, the authentication is determined to be OK only when the primary key K1 is used and the identification information matches the identification information of the registered primary key K1.

  When power is supplied from the AC power supply system, the identification information of the temporary key K2 is deleted by the identification information processing of the temporary key K2 described later. For this reason, the identification information of the temporary key K2 is not erroneously read even if a processing failure occurs or an unauthorized process is performed.

  If it is determined that the authentication is OK by the above collation, the determination in the subsequent step S25 is affirmed and the process proceeds to the subsequent step S26. If the authentication is NG, the determination in the step S25 is denied and the present process is terminated. .

  And in step S26, the locking / unlocking process of the electric lock 22 is performed. That is, if the locking button is operated, the electric lock 22 is locked, and if the unlocking button is operated, the electric lock 22 is unlocked. When the lock button is operated while the electric lock 22 is being locked, and when the unlock button is operated while the electric lock 22 is being unlocked, the electric lock 22 is in the unlocked state. Stays maintained.

  Next, the identification information deleting process of the temporary key K2, which is the third process, will be described with reference to the flowchart of FIG. This process is also executed by the controller 24 at a predetermined time period.

  As shown in FIG. 8, in step S31, it is determined whether power is supplied to the controller 24 from the AC power supply system. If power is being supplied from the DC power supply system because the building is under construction, the determination is denied and the process is terminated.

  Further, when the construction of the building is completed and power is supplied from the AC power supply system, the determination is affirmed and the process proceeds to step S32. In subsequent step S32, it is determined whether or not a predetermined time (for example, several tens of hours) has elapsed after power is supplied from the AC power supply system. If the predetermined time has not elapsed, the determination is denied and the process is terminated.

  On the other hand, if the predetermined time has already elapsed, the determination is affirmed and the process proceeds to step S33. In this step S33, processing for deleting the identification information of the temporary key K2 is executed. In this deletion process, only the identification information of the temporary key K2 stored in the memory 102 is deleted. As a result, when a predetermined time elapses after power is supplied from the AC power supply system, the electric lock 22 cannot be locked and unlocked by the temporary key K2.

  With the above configuration, according to the present embodiment, the following advantageous effects can be obtained.

  When the building is under construction, power cannot be supplied from the AC power supply system to the electric lock 22 of the door body 12. Then, if the connection part 99 and the power supply connection part 74 of the 2nd power supply wiring 98 are connected, power will be supplied to the controller 24 and the electric lock 22 from the DC power supply system | strain which uses DC power supply DC, such as a dry cell and a battery. Is possible. For this reason, even during construction of the building, the electric lock 22 can be locked and unlocked by the temporary key K2 which is an electronic key.

  This eliminates the need to provide a mechanical locking / unlocking device for temporary keys during construction as a countermeasure against power being supplied from the AC power supply system when the building is under construction. Can be prevented. Further, if there is no mechanical locking / unlocking device, the keyhole is not necessary, and the design of the entrance door 11 can be improved.

  The power connection part 74 connected to the second power wiring 98 is drawn from between the door body 12 and the door frame 13. For this reason, connection with DC power supply DC is attained on the outdoor side of the door body 12. In this case, since it is not necessary to provide wiring inside the door frame 13 or the surrounding walls, the wiring configuration for connecting to the DC power source DC can be simplified.

  Further, since the remote operation of unlocking and unlocking with the electronic keys K1 and K2 is performed on the outdoor side of the door body 12, if the DC power source DC is connected on the indoor side of the door body 12, the second power wiring 98 is locked after the electric lock 22 is locked. The connection between the connection part 99 and the power supply connection part 74 cannot be eliminated. In this regard, if the connection between the DC power source DC and the power source connection portion 74 is performed on the outdoor side of the door body 12, the connection can be canceled even after the locking with the electric lock 22. By doing so, it is possible to suppress the consumption of the DC power supply DC.

  The electronic key K includes a primary key K1 possessed by a user and a temporary key K2 possessed by a construction person. Since the building is under construction, when power is supplied from the DC power supply system, the identification information of the temporary key K2 is used for verification in the user authentication process. Therefore, the identification information of the temporary key K2 is associated with the DC power supply system, and the electric lock 22 can be locked and unlocked by the temporary key K2 when power is supplied from the DC power supply system. On the other hand, when power is supplied from the AC power supply system upon completion of the construction of the building, only the identification information of the primary key K1 is used for verification in the user authentication process. For this reason, the identification information of the main key K1 is associated with the AC power supply system, and the electric lock 22 can be locked and unlocked only by the main key K1. As described above, when the power supply systems that supply power to the electric lock 22 are different, if the identification information used for verification in the user authentication process is also different, the primary key K1 and the temporary key K2 according to the power used. And can be used properly.

  When power is supplied from the AC power supply system, the controller 24 deletes the identification information of the temporary key K2, and thereafter, only the electric lock 22 can be locked / unlocked by the primary key K1, and the electric lock 22 can be locked by the temporary key K2. Can no longer be locked and unlocked. Thereby, after the building is completed, it is possible to prevent the entrance door 11 from being illegally released by a construction person who possessed the temporary key K2. Since the identification information of the temporary key K2 is deleted after a predetermined time has elapsed since the power was supplied, the electric lock 22 may be locked and unlocked with the temporary key during the predetermined time. It becomes possible. Thereby, after completion of the construction of the building, when it is necessary to perform a final finishing process before delivery, the person concerned in construction can lock and unlock the electric lock 22 using the temporary key K2.

  And if a building is completed in this way, temporary key K2 will become unnecessary. However, since the temporary key K2 is an electronic key, unlike the key inserted into the keyhole, if the new identification information is registered again, the temporary key K2 can be reused for other entrance doors. This can contribute to waste reduction.

  Since the frame housing member 64 is provided in the frame side member 43 of the energization member 41, when the second energization wiring 45 and the power supply connection portion 74 drawn from between the door body 12 and the door frame 13 are not used, These can be stored in the wiring storage portion 64. For this reason, it can prevent that the drawn-out 2nd electricity supply wiring 45 and the power supply connection part 74 interfere with opening / closing of the door main body 12, and the trouble arises in the opening / closing. In addition, since the non-use energization wiring 45 and the like are not exposed to the outside, the appearance can be maintained.

May be. In this case, it is good to set it as the structure by which the connection part with DC power supply DC is provided in the wall surface around the entrance door 11, and the other end of the said wiring which passes the inside of the door frame 13 is connected to the connection part. As a result, the wiring leading to the DC power source DC is accommodated in the door frame 13 and the surrounding wall without being drawn out to the outside, so that the drawn second energization wiring 45 and the like interfere with the opening and closing of the door body 12. Can be prevented.

  In the above embodiment, the energization member 41 is provided with the power supply connection portion 74 connected to the DC power supply DC, but the verification unit 23 may be provided with a power supply connection portion.
