  Hereinafter, embodiments of an electric lock control device and a security system according to the present invention will be described in detail with reference to the accompanying drawings.

  First, the structure of the security system including the electric lock control device of this embodiment will be described.

  FIG. 1 is a block diagram illustrating an example of a configuration of a security system 10 according to the present embodiment. As shown in FIG. 1, the security system 10 includes an electric lock 20, an opening / closing sensor 35, an operating device 40, an electric lock control device 50, a security control device 70, a monitoring center 80, and a wireless portable terminal 90. Is provided. The electric lock 20, the open / close sensor 35, the operating device 40, the electric lock control device 50, and the security control device 70 are installed in a monitoring target (for example, an office) to be monitored, and the electric lock 20, the operating device 40, The security control device 70 is connected to the electric lock control device 50, and the open / close sensor 35 is connected to the security control device 70. The monitoring center 80 is a system that monitors a monitoring destination using the security control device 70, and is connected to the security control device 70 and the wireless portable terminal 90 via the network 11. The network 11 may be wired or wireless, and can be realized by, for example, a public communication line such as the Internet. In addition, the connection form of each apparatus with which the security system 10 is provided is not limited to this.

  The electric lock 20 is installed on the door 15 at the entrance and exit of a building or room that is a monitoring destination, and is wired to the electric lock control device 50 described later with a plurality of terminals, and under the control of the electric lock control device 50. The door 15 can be opened and closed. The electric lock 20 may be a motor lock that switches between locking and unlocking each time energization, an instantaneous energization type electric lock, or an energization unlocking type electric lock that unlocks when energization is possible. However, it may be an energized lock type electric lock that is locked when energized.

  The open / close sensor 35 is installed on the door 15 at the entrance / exit of the building or room to be monitored, detects the open / close state of the door 15, and guards the open / close information of the door 15 (signal indicating the open / close state). Output to the controller 70. The open / close sensor 35 can be realized by, for example, a magnet sensor.

  FIG. 2 is a diagram illustrating an example of terminal configurations of the electric lock 20 and the open / close sensor 35 of the present embodiment. As shown in FIG. 2, the electric lock 20 includes a SOL1 terminal 21, a SOL2 terminal 22, an unlocking answer terminal 23, a lock COM terminal 24, a locking answer terminal 25, a door COM terminal 26, and a door answer terminal. 27, a terminal 28, a terminal 29, and a solenoid 30.

  The lock COM terminal 24 (an example of a lock common terminal) is a terminal used in common with the unlock answer terminal 23 or the lock answer terminal 25. The unlocking answer terminal 23 (an example of the unlocking terminal) indicates the unlocked state by making (connecting) with the locking COM terminal 24. The locking answer terminal 25 (an example of a locking terminal) indicates a locked state by making (connecting) with the locking COM terminal 24. When the unlocking answer terminal 23 and the lock COM terminal 24 are made, the lock answer terminal 25 and the lock COM terminal 24 are broken (not connected), and the lock answer terminal 25 and the lock COM are not connected. When the terminal 24 is making, the unlocking answer terminal 23 and the lock COM terminal 24 are broken (not connected).

  The SOL1 terminal 21 and the SOL2 terminal 22 (an example of a pair of solenoid terminals) drive the solenoid 30 by driving energization to flow a driving current at a predetermined voltage, and connect the unlocking answer terminal 23 and the lock COM terminal 24 (unlocking). State) and connection (locking state) between the locking answer terminal 25 and the locking COM terminal 24 are switched. When the state of the lock terminal is switched (make-to-break or break-to-make), the line resistance between the terminals of the lock terminal changes.

  The energization method for the SOL1 terminal 21 and the SOL2 terminal 22 differs depending on the type of electric lock such as a motor lock, an instantaneous energization type, an energization unlocking type, or an energization locking type. For example, in the case of a motor lock or a polarized instantaneous energization type electric lock, one of locking and unlocking is performed by energizing the SOL1 terminal 21, and the other is performed by energizing the SOL2 terminal 22. In addition, for example, a non-polar instantaneous energization type electric lock is switched every time the SOL1 terminal 21 or the SOL2 terminal 22 is energized. Further, for example, the electric unlocking type electric lock is unlocked while one of the SOL1 terminal 21 and the SOL2 terminal 22 is energized. Further, for example, the energized locking type electric lock is locked while one of the SOL1 terminal 21 and the SOL2 terminal 22 is energized.

  A door COM terminal 26 (an example of a common door terminal) and a door answer terminal 27 (an example of a door terminal) indicate the open / closed state of the door 15, and make (connect) when the door 15 is closed, and the door 15 opens. If it is, break (disconnect). In the present embodiment, the terminal 28 and the terminal 29 are not used, but in an electric lock, a connector in which nine terminals are combined is generally shown.

  The open / close sensor 35 also indicates the open / closed state of the door 15 and makes (connects) when the door 15 is closed, and breaks (disconnects) when the door 15 is open. That is, the open / close sensor 35 and the door answer terminal 27 are interlocked.

  Returning to FIG. 1, the operating device 40 reads an ID from a key such as a non-contact IC card or an IC tag and transmits the ID to an electric lock control device 50 described later. The operating device 40 can be realized by, for example, a card reader. The operating device 40 may be realized integrally with the electric lock control device 50.

  The electric lock control device 50 controls the electric lock 20 to control opening and closing of the door 15. For example, the electric lock control device 50 collates (authenticates) the ID received from the operating device 40, and when the collation is successful, locks or unlocks the electric lock 20 and controls the opening and closing of the door 15.

  In particular, in the present embodiment, the electric lock control device 50 performs control to identify which terminal each terminal of the electric lock 20 is before and after the electric lock 20 is installed on the door 15 and the operation is started. Do. In this embodiment, since each terminal of the electric lock 20 can be specified in this way, even if the wiring between the contact of the electric lock control device 50 and each terminal of the electric lock 20 is erroneously wired. The electric lock 20 can be correctly operated by controlling the electric lock 20 in consideration of the above (in accordance with the specified terminal instead of following the wiring).

  In the present embodiment, the electric lock 20 can be applied regardless of the type of electric lock. However, since the electric lock generally does not return the answer of locking / unlocking unless the door is closed, the control for specifying each terminal of the electric lock 20 is performed on the precondition that the door is in the closed state.

  The electric lock control device 50 can be realized by, for example, a control panel including a chip set having a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and the like. In addition, electric power is supplied to the electric lock control device 50 from a power source (not shown), and it is possible to apply energization and voltage to each terminal of the electric lock 20 from the electric lock control device 50.

  FIG. 3 is a block diagram illustrating an example of the configuration of the electric lock control device 50, the security control device 70, and the monitoring center 80 of the present embodiment. As shown in FIG. 3, the electric lock control device 50 includes a storage unit 51, an acquisition unit 53, a door terminal specifying unit 54, a first energizing unit 55, a first specifying unit 56, and a second energizing unit 57. A second specifying unit 58, an electric lock control unit 59, a third specifying unit 60, a determination unit 61, a notification unit 62, and a transmission unit 63.

  The storage unit 51 stores various programs executed by the electric lock control device 50, various information used for various processes performed by the electric lock control device 50, and the like. The storage unit 51 can be realized by a memory such as a ROM or a RAM (Random Access Memory), for example. The storage unit 51 includes a wiring information storage unit 52. Details of the wiring information storage unit 52 will be described later.

  The acquisition unit 53 acquires opening / closing information indicating the opening / closing state of the door 15 from the security control device 70. The opening / closing information is information based on the signal output of the opening / closing sensor 35.

  The door terminal identification unit 54 identifies the door answer terminal 27 based on the opening / closing information acquired by the acquisition unit 53. More specifically, since the opening / closing sensor 35 and the door answering terminal 27 operate in conjunction with each other, the door terminal specifying unit 54 designates the terminal that makes and breaks in conjunction with the state indicated by the opening / closing information as the door answering terminal 27. Identify.

  The first energization unit 55 conducts the energization of the search by causing the search current to flow between the terminals in the state where the opening / closing information acquired by the acquisition unit 53 indicates the closed state, that is, in the closed state. This exploration energization is performed for the purpose of identifying the terminals that are made out of the plurality of terminals of the electric lock 20.

  The first specifying unit 56 specifies two pairs of terminals that are made based on the search energization result of the first energization unit 55. Two pairs of terminals that are made up are a pair of door COM terminal 26 and door answer terminal 27, a pair of locking answer terminal 25 and lock COM terminal 24, or a pair of unlocking answer terminal 23 and lock COM terminal 24. Yes (because the electronic lock 20 may be locked or unlocked). However, at this stage, it cannot be determined whether it is a pair of the locking answer terminal 25 and the lock COM terminal 24 or a pair of the unlocking answer terminal 23 and the lock COM terminal 24.

  The second energization unit 57 performs drive energization to flow a drive current for driving the solenoid 30 with a predetermined voltage (for example, 24 V) between the terminals other than the two pairs of terminals. This drive energization is performed for the purpose of making or breaking the locking answer terminal 25 and the lock COM terminal 24 by driving the solenoid 30 and breaking or making the unlocking answer terminal 23 and the lock COM terminal 24.

  The second specifying unit 58 specifies the two terminals that have been energized as the SOL1 terminal 21 and the SOL2 terminal 22 when the line resistance between any one of the two pairs of terminals has changed due to the drive energization. . Moreover, the 2nd specific | specification part 58 pinpoints the terminal with which makeup is continued among a pair of terminal from which line resistance changed to the lock COM terminal 24. FIG. Moreover, the 2nd specific | specification part 58 specifies the terminal which is not the door answer terminal 27 of a pair of terminal from which line resistance did not change among the two pairs of terminals to the door COM terminal 26. Thereby, it is possible to specify which terminal other than the unlocking answer terminal 23 and the locking answer terminal 25 among the terminals of the electric lock 20 is.

  The electric lock control unit 59 controls the electric lock 20 based on the identification result by the second identification unit 58. For example, the electric lock control unit 59 takes into account miswiring (instead of following the wiring) even when a miswiring has occurred in the wiring between the contact of the electric lock control device 50 and each terminal of the electric lock 20. The electric lock 20 is controlled (according to the specified terminal). However, since the unlocking answer terminal 23 and the locking answer terminal 25 are not specified at the stage before the operation of the electric lock 20 is started, the control of the electric lock 20 in consideration of these incorrect wirings is performed. Is performed after the unlocking answer terminal 23 and the locking answer terminal 25 are specified by the third specifying unit 60 described later. Thereby, even if it is a case where the incorrect wiring has arisen between the electric lock control apparatus 50 and the electric lock 20, an electric lock can be operated correctly.

  When the open / close state of the open / close information acquired by the acquisition unit 53 changes, the third specifying unit 60 specifies the lock COM terminal 24 and the terminal that has been made as the unlocking answer terminal 23, and the lock COM terminal 24 A terminal that has not been made is identified as the locking answer terminal 25. Note that the unlocking answer terminal 23 and the locking answer terminal 25 are specified by the third specifying unit 60 after the operation of the electric lock 20 is started.

Here, the wiring information storage unit 52 will be described. The wiring information storage unit 52 stores wiring information indicating which terminal of the electric lock 20 is wired to each contact of the electric lock control device 50.
That is, the wiring information storage unit 52 stores information indicating normal wiring between the electric lock control device 50 and the electric lock 20 as wiring information.

  The determination unit 61 determines whether or not the wiring between each contact of the electric lock control device 50 and each terminal of the electric lock 20 matches the wiring indicated by the wiring information in the wiring information storage unit 52.

  When the determination unit 61 determines that they do not match, the notification unit 62 notifies that the wiring is incorrect. The notification unit 62 can be realized by, for example, a display, a speaker, an alarm device, or the like, and performs display notification, audio notification, or visual notification that the wiring is incorrect.

  When the determination unit 61 determines that they do not match, the transmission unit 63 transmits a notification signal indicating that the wiring is incorrect to the security control device 70. The transmission unit 63 can be realized by an existing communication device such as a communication interface, for example.

  In addition, the electric lock control apparatus 50 does not need to make all the parts mentioned above into an essential structure, and it is good also as a structure which abbreviate | omitted that part. For example, in the electric lock control device 50 of FIG. 3, both notification by the notification unit 62 and transmission of the notification signal by the transmission unit 63 are performed, but either configuration may be omitted.

  Returning to FIG. 1, the security control device 70 switches the security mode between, for example, a security state and a security release state, and executes a security operation according to the security mode. Here, the security mode is a mode that determines whether or not to notify the reporting destination when abnormality is detected in the monitoring area or whether or not notification to the monitoring area is possible, and the security control device 70 when an abnormality is detected. This is a mode for determining the operation. The security state is a security mode that is set when security is required. When the security control device 70 receives a detection signal that is issued when an abnormality is detected by a sensor (not shown), an alarm that notifies the abnormality is issued. In this state, the monitoring center 80 is notified. The security release state is a security mode that is set when security is not required. Even when the security control device 70 receives a detection signal that is detected when an abnormality is detected by a sensor (not shown), the monitoring center 80 is informed. In this state, none of the alarm notification, the detection of abnormality in the monitoring area, and the abnormality notification to the notification destination terminal are performed.

  In addition, for example, when the security mode is the security state, the security control device 70 outputs an electric lock unlocking permission command to the electric lock control device 50, or when the security mode is the security release state, An unlocking permission command for the electric lock is output to the electric lock control device 50. In this case, the electric lock control device 50 performs control to unlock the electric lock 20 only when the security mode is the security release state. The security control device 70 can also output an unlocking / locking command for the electric lock 20 to the electric lock control device 50.

  Further, the security control device 70 notifies the opening / closing information to the electric lock control device 50 based on the signal output from the opening / closing sensor 35 or receives a notification signal from the electric lock control device 50 to perform control related to the notification. As shown in FIG. 3, the security control device 70 includes an opening / closing information receiving unit 71, an opening / closing information transmitting unit 72, a notification signal receiving unit 73, a notification unit 74, and a notification signal transmission unit 75.

  The opening / closing information receiving unit 71 sequentially receives opening / closing information (a signal indicating an opening / closing state) of the door 15 from the opening / closing sensor 35. The opening / closing information transmitting unit 72 transmits the opening / closing information received by the opening / closing information receiving unit 71 to the electric lock control device 50.

  The notification signal receiving unit 73 receives a notification signal indicating that the wiring is an incorrect wiring transmitted from the electric lock control device 50. The notification unit 74 notifies that the wiring is incorrect based on the notification signal received by the notification signal reception unit 73. The notification unit 74 can be realized by, for example, a display, a speaker, an alarm device, or the like, and performs display notification, audio notification, or visual notification that the wiring is incorrect. The notification signal transmission unit 75 transmits the notification signal received by the notification signal reception unit 73 to the monitoring center 80 via the network 11.

  Note that the security control device 70 does not have to have all the above-described components as essential configurations, and may have a configuration in which some of them are omitted. For example, in the security control device 70 of FIG. 3, both notification by the notification unit 74 and transmission of the notification signal by the notification signal transmission unit 75 are performed, but either configuration may be omitted.

  When the monitoring center 80 receives a report from the security control device 70, the monitoring center 80 instructs the security guard to dispatch to the monitoring destination, or reports to related organizations such as the police and the fire department as necessary. In addition, when the monitoring center 80 according to the present embodiment receives a notification signal indicating that the wiring is incorrect from the security control device 70, the monitoring center 80 of the worker who is working at the monitoring destination (security contracting destination) where the incorrect wiring is generated. The mobile terminal 90 is informed that the wiring is incorrect. As shown in FIG. 3, the monitoring center 80 includes a notification signal reception unit 81 and a notification signal transmission unit 82.

  The notification signal receiving unit 81 receives a notification signal from the security control device 70 via the network 11. The notification signal transmitting unit 82 transmits the notification signal received by the notification signal receiving unit 81 to the wireless portable terminal 90 of the monitoring destination worker where the electric lock control device 50 is installed via the network 11 to perform notification. Make it.

  Note that the monitoring center 80 does not have to have all of the above-described units as essential configurations, and may have a configuration in which some are omitted.

  Next, operation | movement of the security system of this embodiment is demonstrated.

  FIG. 4 is a flowchart illustrating an example of a flow of processing performed by the electric lock control device 50 of the present embodiment. The process shown in FIG. 4 is a stage before the electric lock 20 is installed on the door 15 and the operation is started, and the door COM terminal 26 and the door answer terminal 27 are made, that is, the door is closed. Start with At this stage, since the SOL1 terminal 21 to the terminal 29 of the electric lock 20 are all unknown terminals, the SOL1 terminal 21 to the terminal 29 will be described as a terminal A to a terminal I, respectively.

  First, the acquisition unit 53 acquires the opening / closing information output from the opening / closing sensor 35 and input to the security control device 70 from the security control device 70 (step S100).

  Subsequently, the door terminal identification unit 54 identifies the door answer terminal 27 based on the opening / closing information acquired by the acquisition unit 53 (step S102). Here, it is assumed that the terminal G makes and breaks in conjunction with the state indicated by the opening / closing information. In this case, the door terminal specifying unit 54 specifies the terminal G as the door answer terminal 27.

  Subsequently, the first energization unit 55 conducts the energization for exploration by causing the exploration current to flow between the terminals A to I (step S104). That is, the energization is performed for the pair that each terminal can take.

  Subsequently, the first specifying unit 56 specifies the two pairs of terminals that are made based on the search energization result (step S106). Here, it is assumed that the terminal D, the terminal E, the terminal F, and the terminal G are identified as being made.

  Subsequently, the second energization unit 57 performs drive energization to flow a drive current for driving the solenoid 30 with a predetermined voltage (for example, 24 V) between the terminals other than the two pairs of terminals (step S108). That is, drive energization is performed on a pair of terminals A, B, C, H, and I.

  Subsequently, when the line resistance between any one of the two pairs of terminals is changed due to the drive energization, the second specifying unit 58 determines the two terminals that have been energized as the SOL1 terminal 21 and the SOL2 terminal 22. (Step S110). Here, it is assumed that the line resistance between the terminals D and E is changed by driving energization to the terminals A and B. In this case, the second specifying unit 58 specifies the terminal A and the terminal B as the SOL1 terminal 21 and the SOL2 terminal 22.

  Moreover, the 2nd specific | specification part 58 pinpoints the terminal with which makeup is continued among a pair of terminal from which line resistance changed to the lock COM terminal 24. FIG. Here, it is assumed that makeup of terminal D is continued. In this case, the second specifying unit 58 specifies the terminal D as the lock COM terminal 24.

  Moreover, the 2nd specific | specification part 58 specifies the terminal which is not the door answer terminal 27 of a pair of terminal from which line resistance did not change among the two pairs of terminals to the door COM terminal 26. Here, it is assumed that the line resistance between the terminals F and G has not changed. In this case, the second specifying unit 58 specifies the terminal F as the door COM terminal 26 (because the terminal G is specified as the door answer terminal 27).

  Subsequently, the electric lock control unit 59 controls the electric lock 20 based on the identification result by the second identification unit 58 (step S112). For example, the electric lock control unit 59 does not follow the wiring between the contacts of the electric lock control device 50 and each terminal of the electric lock 20 but controls the electric lock 20 according to the specified terminal.

  Subsequently, when the operation of the electric lock 20 is started, the third specifying unit 60 changes the lock COM terminal 24 and the terminal that has been made when the open / close state of the open / close information acquired by the acquiring unit 53 changes. The unlock answer terminal 23 is specified, and the lock COM terminal 24 and the unmake terminal are specified as the lock answer terminal 25 (step S114). Here, it is assumed that when the open / close state of the open / close information changes, the lock COM terminal 24 and the terminal C are made and the lock COM terminal 24 and the terminal E are broken. In this case, the third specifying unit 60 specifies the terminal C and the terminal E as the unlocking answer terminal 23 and the locking answer terminal 25, respectively.

  As described above, according to the present embodiment, in order to perform control for specifying which terminal each terminal of the electric lock 20 is before and after the electric lock 20 is installed on the door 15 and the operation is started. The terminals of the electric lock 20 can be specified, and even if the wiring between the contacts of the electric lock control device 50 and the terminals of the electric lock 20 is miswired, the miswiring is taken into consideration (follow the wiring). By controlling the electric lock 20 (instead of the specified terminal), the electric lock 20 can be operated correctly.

  Moreover, according to this embodiment, in addition to operating the electric lock 20 correctly when the wiring between the contact of the electric lock control device 50 and each terminal of the electric lock 20 has an incorrect wiring, the fact that the wiring is incorrect. Since the notification and the notification signal are transmitted, it is possible to notify the user and the guards that the wiring is incorrect.

(Modification)
In addition, this invention is not limited to the said embodiment, A various deformation | transformation is possible. For example, in each of the above embodiments, the example in which the lock COM terminal 24 and the door COM terminal 26 are separate terminals has been described. However, the present invention is not limited to this, and as shown in FIG. The electric lock 120 may be the same terminal (COM terminal 124) as the door COM terminal. Moreover, as shown in FIG. 6, the lock COM terminal, the door COM terminal, and the SOL2 terminal may be the same terminal (COM terminal 222), and the electric lock 220 from which the unlocking answer 23 is omitted may be used. In this way, the number of terminals can be reduced. In this case, the second specifying unit specifies, as the SOL1 terminal 21, a terminal that is not the COM terminal 222 among the two terminals that have undergone the drive energization when the line resistance between any of the terminals changes due to the drive energization.
