Description

  The present invention relates to an electric lock system.

  As an electric lock system that performs a locking / unlocking operation of an electric lock fixed to a door by a controller formed separately from the electric lock, one disclosed in Patent Document 1 is known. In this conventional example, between the electric lock and the electric lock control panel (controller) arranged outside the door, the electric lock side adapter arranged inside the door and connected to the electric lock, and arranged outside the door. A control panel side adapter connected to the electric lock control panel is interposed. Both adapters are provided with a locking ID holding / verifying means, and the unlocking operation of the electric lock is performed on condition that the locking ID stored in the locking ID holding / verifying means coincides. Even if the line is illegally cut and the electric lock is supplied with power, the electric lock is not unlocked because the lock IDs do not match.

  However, in the prior art described above, the locking ID is set for each locking operation and is discarded until the next unlocking operation. Therefore, the setting and registration operation of the locking ID is required for each locking and unlocking operation, and the control is complicated. In addition, there is a problem that it takes time to recover when a lock ID is flawed due to the locking / unlocking operation being stopped due to a power failure or the like.

  This problem can be solved by continuously using the ID set when the electric lock is newly incorporated in the electric lock system. In this case, the connection between the electric lock and the controller is illegal. After cutting, there is a possibility that an unauthorized ID is registered in the electric lock pretending to be the unique ID registration mode and an unlocking operation is performed with the unauthorized ID.

In order to solve this problem, it is possible to add authentication for the preset authentication ID to the condition for changing to the unique ID registration mode. In this case, the authentication ID is separately added to the electric lock incorporated in the system in the initial state. An operation for registration is required, which causes a disadvantage that the operability is significantly lowered.
Japanese Patent Laid-Open No. 2006-118312

  The present invention has been made to eliminate the above-described drawbacks, and an object of the present invention is to provide an electric lock system that is highly resistant to unauthorized operation and simple in initial setting operation.

  The electric lock system includes a controller 3 fixed to the outside of the door 1 and one or more electric locks 2 fixed to the door 1. The electric lock 2 is configured to drive an appropriate actuator based on a locking / unlocking request from the controller 3 to advance or retract the locking body 12 such as a lock rod or a hook to a strike on the door frame side.

  The electric lock 2 includes, in addition to the mechanism parts such as the actuator and the locking body 12, a control part for controlling the actuator, interface control with the controller 3, etc., or a sensor part for detecting the unlocking and unlocking state. The electric lock 2 is not limited to one in which the above-described components are housed in a single case, but includes one that is distributed in the door 1. For example, in the case of the lock / unlock state detection sensor 7 of the electric lock 2, in addition to the one integrated in the case housing the mechanical part, it is separately fixed in the door 1 and wired or wirelessly to the control part in the case. Includes connected ones.

  The locking / unlocking of the electric lock 2 is performed by a locking / unlocking request from the controller 3, and the controller 3 adds a unique ID set to the electric locking 2 at least when outputting the unlocking request, and requests the unlocking Is unlocked by driving the actuator on condition that the unique ID output from the controller 3 and the unique ID stored in the own station match. The transmission of the unlocking request from the controller 3 is, for example, a condition that the authentication device establishes authentication for pressing the locking / unlocking operation button installed in the controller 3 or for the locking / unlocking operation to the locking / unlocking operation device installed in the door 1. It can be.

  When the electric lock 2 is unlocked, it is necessary to match the unique ID, so that even if the wiring between the electric lock 2 and the controller 3 is cut and a drive device to the electric lock 2 is connected in the middle, there is no unique ID. Therefore, the unlocking operation is not performed.

  Further, the registration of the unique ID in the electric lock 2 is performed on condition that the unique ID registration request from the controller 3 and the unlocked state detection of the unlocking state detection sensor 7 held as information inside the electric lock 2 are performed. Even if a signal disguised as an unlocked state is input from an illegally connected drive device, the output of the unlocked / unlocked state detection sensor 7 can be reversed unless the unlocking operation of the electric lock 2 is actually performed. Therefore, the unique ID of the electric lock 2 cannot be rewritten illegally.

  In addition, the locking / unlocking state detection sensor 7, the communication interface with the controller 3, the storage unit for the unique ID, the locking / unlocking control unit, etc. are resources used as part of the basic configuration of the electric lock 2 during normal operation. After these are added to the system, it is possible to belong to the controller 3 simply by executing a predetermined procedure including the unlocking operation, so that the initial setting operation is extremely simple and the usability is improved.

  According to the present invention, it is possible to increase resistance to unauthorized operations and simplify initial setting operations.

  As shown in FIG. 1, the electric lock system includes an electric lock 2 fixed to the door 1, a reader unit 13, and a controller 3 fixed to the outside of the door 1 such as an indoor wall surface. The door 1 side component is connected by a wired or wireless communication path (hereinafter “line 14”). In the illustrated example, the electric lock 2 is a system configured by using two main and sub, but the number of the electric lock 2 may be one, or three or more.

  The electric lock 2 is locked and unlocked by a locking / unlocking operation from inside and outside the room, and the locking / unlocking operation from the room is performed by operating the locking / unlocking operation unit 15 such as a locking / unlocking button disposed on the controller 3. The operation from the outside is performed on the condition that the controller 3 of the portable device 16 possessed by the user is authenticated. The authentication of the portable device 16 is performed by verifying the match between the authentication ID transmitted from the portable device 16 by radio or the like and received via the reader unit 13 and the authentication ID held on the controller 3 side. The authentication ID is transmitted from the portable device 16 by pressing the lock / unlock button 16a on the portable device 16 side or by an electronic response to the request signal from the reader unit 13 by pressing the request switch 13a disposed on the reader unit 13. Done.

  FIG. 2 shows a main part of the controller 3 as a block diagram. The controller 3 includes an ID processing unit 5 controlled by the control unit 3a, switches 1 and 2 (SW1, SW2), a display unit 3b, a locking / unlocking operation unit 15, an authentication unit 3c, a locking / unlocking signal output unit 6, and a communication interface 3e. The lock / unlock state input unit 3f and the door open / close state input unit 3g are provided. The control unit 3a includes a CPU and a ROM that stores a program.

  The ID processing unit 5 includes an ID generation unit 5a and an ID storage unit 4, and the ID generation unit 5a generates a unique ID assigned to the electric lock 2 under a unique ID registration mode described later. The unique ID is generated by using a random number initialized by an operation time or the like, or encoding an operation procedure. The control unit 3a stores the unique ID generated by the ID generation unit 5a in the ID storage unit 4 and outputs it to the line 14 together with the unique ID registration request via the communication interface 3e.

  The switches 1 and 2 (SW1 and SW2) are used to change the controller 3 to the initial setting mode. When the controller 3a detects the operation of the switches 1 (SW1) and 2 (SW2), Call and execute the initial setting program stored in. The switch 1 (SW1) is mainly used for work selection, and the switch 2 (SW2) is used for work determination.

  The display unit 3b displays the work procedure in the initial setting mode in addition to the state display around the door 1 such as the unlocked state.

  As described above, the locking / unlocking operation unit 15 is used for operating the electric lock 2 from the indoor side, and when the control unit 3a detects an operation on the locking / unlocking operation unit 15, the locking / unlocking operation unit 15 determines the type of locking / unlocking. Thereafter, a locking / unlocking request that matches the locking / unlocking type is output to the line 14 from the locking / unlocking signal output unit 6.

  The communication interface 3e converts various data generated inside into a predetermined protocol and outputs the data to the line 14 or fetches data from the line 14. As a system server, the controller 3 grasps the status of the reader unit 13 and the electric lock 2 using a polling protocol in a normal operation mode, and polls output to the electric lock 2 and the reader unit 13. The electric lock 2 designated in the data reports the open / closed state and unlocked state of the door 1 as a polling response. Further, the reader unit 13 designated as the polling data transmission destination outputs the authentication ID received from the portable device 16 as polling response data. Furthermore, the controller 3 performs setting polling in the above-described initial setting mode.

  The authentication unit 3c compares the authentication ID included in the polling response data from the reader unit 13 with that of the portable device 16 set in advance with the data in the authentication ID storage unit (not shown), and To do. When authentication by the authenticating unit 3c is established or when an operation to the locking / unlocking operation unit 15 on the controller 3 is performed, the controller 3 temporarily stops polling and outputs a locking / unlocking request signal to the line 14.

  The door opening / closing state input unit 3g and the locking / unlocking state input unit 3f take in signals indicating the door opening / closing state and the locking / unlocking state output by the electric lock 2 as necessary, and use them for control.

  FIG. 3 shows a main part of the reader unit 13. The reader unit 13 communicates with the portable device 16 described above, and the radio signal receiver 13c, the request signal output unit 13d, the request switch 13a, the communication interface 13e, the door open / close state input unit 13f connected under the control unit 13b. And a locking / unlocking state input unit 13g.

  The radio signal receiver 13 c receives the authentication ID output from the portable device 16. The request signal output unit 13d outputs a request signal to the portable device 16 when the request switch 13a is pressed. The portable device 16 that has received the request signal transmits its own authentication ID and the like to the reader unit 13 as a response signal. The request signal can be transmitted while being superimposed on an electromagnetic wave for supplying energy required for the response operation of the portable device 16.

  FIG. 4 shows the configuration of the electric lock 2. The electric lock 2 includes a control unit 2a, a locking / unlocking state detection sensor 7, a door sensor 11, a motor control unit (locking / unlocking driving unit 10), an ID processing unit 9, a communication interface 2b, a door open / closed state output unit 2c, and a locking / unlocking. It has a status output unit 2d. The locking / unlocking state detection sensor 7 determines the locking / unlocking state by detecting the position of the locking body 12 driven by, for example, a motor as an actuator, or determines the locking / unlocking state from the state of the motor power transmission system to the locking body 12. Determine.

  The door sensor 11 detects the open / closed state of the door 1. The door sensor 11 may be integrated into a case that accommodates the locking body 12, or may be disposed outside the case and connected to the control unit 3a by wiring or the like. In this embodiment in which two electric locks 2 are used, it is sufficient that the door sensor 11 is provided on one of the electric locks 2.

  The door opening / closing state output unit 2c and the locking / unlocking state output unit 2d output the states of the door sensor 11 and the locking / unlocking state detection sensor 7 to the line 14. In order to prevent an illegal state change operation from the line 14 side, the sensor 7 and the output units 2c and 2d are connected via a photocoupler or the like.

  The motor control unit 10 is activated when the control unit 2a receives a locking / unlocking request signal from the controller 3, and drives the locking body 12 to the locking / unlocking position.

  The ID processing unit 9 includes an ID writing determination unit 9 a and an ID storage unit 8. When the ID writing determination unit 9 a receives a unique ID registration request from the controller 3, The unique ID transmitted from the controller 3 only when the output of the door sensor 11 is confirmed and the unlocking state detection sensor 7 detects the unlocked state or when the door sensor 11 detects the door open state. Is written in the ID storage unit 8.

  FIG. 5 shows a flowchart of the operation of the controller 3. As described above, the controller 3 collects information such as the electric lock 2 by the normal polling operation (step SC1), and when adding a new electric lock 2 to the system, first, the mode is set to the initial setting mode. Change to The mode change operation is performed by first turning on both the switches 1 and 2 (SW1, SW2) for a predetermined time (in this example, 2 seconds) or more and then releasing both switches within the predetermined time. In FIG. 5, the switch-on state and the on-state duration time are detected in steps SC2 and SC3, and the mode change is confirmed in steps SC4, 5, and 6. If the mode change condition is not satisfied, the request is canceled (step SC3, 6).

  When the mode change is executed, the display unit 3b then prompts an initial menu selection using the switch 1 (SW1) by an instruction message to the user, and changes the designation process by pressing the switch 1 (SW1). (Step SC7, 8). The assignment of the unique ID to the electric lock 2 is executed by pressing the switch 2 (SW2) after selecting the initial setting mode (steps SC9, 10). If not executed, the process returns to the mode selection step. (Step S11).

  When the initial setting mode is entered, the user is required to perform the opening / closing operation or unlocking operation of the door 1 within a predetermined time (30 seconds), the timer for this is started (step SC12), and then the switch When 2 (SW2) is turned OFF (step SC13), the setting boring operation shown in FIG. 6 is started.

  On the other hand, if the change to the initial mode is not selected in step SC2, the response from the reader unit 13 by the normal polling operation is confirmed (step SC14). A locking / unlocking operation is requested (steps SC15 and SC16).

  As shown in FIG. 6, when the switch 2 (SW2) is operated in step SC13, the normal mode polling is shifted to the setting polling mode (step SC20). The polling mode at the time of setting is continued within the time set for performing the operation on the door 1 described above, and returns to the control start state after the time is continued (step SC21). Even within the set time, it can be canceled by operating the switch 1 (SW1) (step SC22).

  If the operation is not canceled in step SC22, the control unit 3a prompts the user to press the switch and confirms that the switch 2 (SW2) is pressed in order to confirm the user's explicit intention to install the electric lock 2 in the system. Is confirmed, a unique ID is set and transferred to the line 14 (steps SC23, 24, 25).

  Thereafter, the controller 3 returns to the normal polling operation and returns to the setting mode selection step (steps 26, 27, 28).

  FIG. 7 shows a flowchart of the operation of the electric lock 2. When the control unit 2a receives the data on the line 14 (step SL1), the electric lock 2 determines whether or not normal polling is received (step SL2). If the polling is normal polling, the polling data from the controller 3 is determined. The door opening / closing information of the door 1 is compared with the output of the door sensor 11 in the electric lock 2 (step SL3).

  In this embodiment in which only one of the two electric locks 2 detects the open / closed state of the door 1, the polling response to the controller 3, that is, the open / close information of the door 1 known by the controller 3. The change is executed only when there is no polling response from another electric lock 2 within a predetermined time (steps SL4 to SL7).

  On the other hand, if the received data is not normal polling data, as shown in FIG. 8, it is determined whether the received data is set polling data (step SL8). If the received data is set polling data, the polling data is determined. It is determined whether or not there is door opening data, that is, whether or not the user has performed the door 1 opening operation (step SL9). When door opening data is included in step SL9, the output of the unlocking state detection sensor 7 of the electric lock 2 is detected, and when the unlocking state is detected, that is, the setter unlocks the electric lock 2. 9 is executed, the unique ID registration step shown in FIG. 9 is executed (step SL10).

  On the other hand, if the setting polling data does not include the door 1 opening data or is not in the unlocked state, the controller for opening the door 1 and opening the door 1 by the user for a predetermined time. Waiting for the update of the data on the third side (steps SL11, 12, 13).

As shown in FIG. 9, the unique ID registration step is executed after receiving the data after confirming the unlocked state in step SL10 (step SL14). When the data is received, it is determined whether or not the normal polling is performed (step SL15). When the normal polling is performed, in the system including the two electric locks 2 in which the normal polling operation shown in FIG. The setter can determine whether the electric lock 2 is the main lock, and the system sets the electric lock 2 on the side where the locking operation is performed from the unlocked state as the sub lock. For this reason, when the received data is set polling (step SL16), first, it is determined whether the locking / unlocking information in the polling data matches the output of the locking / unlocking state detection sensor 7 in the electric lock 2 ( Step SL17). Immediately after the locking operation of the sub-lock, the controller 3 has not received a polling response. Therefore, the polling data for the sub-lock indicates unlocking information. A sub-lock is temporarily determined (steps SL18 and 19).

  After locking one of the above locks and performing the main / sub distinction operation, the final registration of the unique ID prompts the user to open the door and confirms this on the condition that it is reflected in the polling data Therefore, first, data reception is waited (step SL20). If it is confirmed in step SL21 that the received data is not normal polling, it is determined in step SL22 whether there is door 1 open data in the polling data, that is, whether the door 1 open state is recognized by the controller 3 or not. Determine (step SL22).

  When the door 1 opening data is confirmed in step SL22, which is the main lock is finally determined and registered (step SL23), and then a unique ID registration request is waited (steps SL24, 25, 26) When the unique ID is transmitted, the unique ID is stored in the unique ID storage unit 4 (step SL27).
