Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, in a storage device such as a delivery box composed of a plurality of lockers provided with electric locks on the doors, an electric lock system for controlling locking / unlocking of the electric locks is used. Conventionally, the electric lock has been controlled by an instruction signal based on an input operation received by a host device and an opening / closing result of the door detected by a detection sensor. When the number of lockers constituting the storage device exceeds a certain number, relay devices including control circuits for grouping a plurality of lockers for each group and controlling each electric lock for each group are further provided. The host device is connected in parallel to each relay device via wiring, and controls the electric locks provided on the plurality of lockers belonging to each group. FIG. 6 is a block diagram showing the configuration of a conventional electric lock system 9.

[0005] However, if the host device is connected in parallel to each electric lock or each relay device in this way, the wiring becomes concentrated and complicated for each host device or relay device, and noise is likely to be mixed in. Also, in such a conventional electric lock system 9, in order to reduce the noise that is likely to be mixed in due to the complicated wiring, the wiring is required to have a transmission speed of a certain level or higher. For example, for the control process of locking / unlocking the electric lock and the detection process of opening / closing the door, a relatively expensive wiring with a high transmission speed such as RS485 was used. For this reason, the manufacturing cost of the conventional electric lock system 9 was high.

[0006] An object of the present invention is to provide an electric lock system that can suppress the generation of noise while reducing costs with a simple configuration and enable the control of locking and unlocking of electric locks.

Means for Solving the Problems

[0007] In view of such a situation, the present inventor conducted intensive studies and as a result, by connecting an operating device and each electric lock in cascade with wiring composed of input / output lines, power lines, and ground lines, and implementing processing in an electric lock system using a single-ended microcomputer, it became possible not to provide a relay device, and it was found that noise and cost could be suppressed, leading to the present invention.

[0008] The electric lock system according to the present invention includes a plurality of electric lock modules respectively provided on a plurality of doors, an operation device that performs an operation instructing locking / unlocking of any one of the plurality of electric lock modules, and a transmission unit that electrically connects the operation device and the plurality of electric lock modules. An opening / closing detection unit that detects opening and closing of the door, a locking / unlocking unit that locks / unlocks the door, and an electric lock control unit that controls the locking / unlocking unit are included in each of the electric lock modules. A reception unit that receives a locking operation / unlocking operation for the electric lock module, and an information processing unit that generates an instruction signal regarding locking / unlocking of the electric lock module based on at least one of the opening / closing detection information detected by the opening / closing detection unit and the operation information received by the reception unit and transmits the instruction signal to the electric lock module are included in the operation device. The transmission unit transmits any one of the opening / closing detection information, the operation information, and the instruction signal between the operation device and any one of the plurality of electric lock modules and between the plurality of electric lock modules.

[0009] According to such an electric lock system, it is possible to provide an electric lock system that can suppress the generation of noise while reducing costs with a simple configuration and enable control of locking / unlocking of the electric lock.

[0010] Further, it is preferable that the transmission speed in the transmission unit is 10 Kbps or less.

[0011] According to the configuration of such an electric lock system, by setting the transmission speed to a low speed of 10 Kbps or less, not only can costs and power consumption be reduced, but also the transmission of electrical signals in the control process of locking / unlocking the electric lock and the detection process of opening and closing the door can be stabilized.

[0012] Further, it is preferable that at least one of the locking / unlocking unit and the information processing unit is a single-ended type microcomputer.

[0013] According to the configuration of such an electric lock system, since the single-ended microcomputer has a simple structure, it is specialized in performing the process of detecting the opening and closing of the door and the process of controlling the electric lock, and the cost is reduced.

[0014] In addition, a connection wiring including input / output lines, power lines, and ground lines having a three-state configuration is included in the transmission unit, and it is preferable that the connection wiring cascades between the operation device and any one of the plurality of electric lock modules.

[0015] According to the configuration of such an electric lock system, since the input / output lines have a three-state configuration, it is possible to prevent the input / output lines from having a high impedance and further improve the noise resistance.

[0016] In addition, a connection wiring including input / output lines, power lines, and ground lines having a three-state configuration is included in the transmission unit, and it is preferable that the connection wiring cascades between the plurality of electric lock modules.

[0017] According to the configuration of such an electric lock system, by cascading between a plurality of electric lock modules by a transmission unit including input / output lines having a three-state configuration, the wiring of the entire electric lock system can be further simplified.

[0018] In addition, when such an electric lock system is mounted on a storage device including a plurality of storage chambers, the storage device can provide a configuration that reduces costs by simplifying the wiring, suppresses the generation of noise, is easy to install, and has a low and stable signal transfer speed.

Effect of the Invention

[0019] Thereby, the present invention can provide an electric lock system capable of controlling locking / unlocking of an electric lock while reducing costs with a simple configuration.

Embodiments for Carrying Out the Invention

[0021] Hereinafter, embodiments according to the present invention will be described with reference to the drawings. In each figure, components with the same reference numerals are shown to be the same components, and their descriptions will be omitted.

[0022] The electric lock system 1 according to the present invention will be described. FIG. 1 is a block diagram showing the electrical configuration of the electric lock system 1 according to the present invention. The electric lock system 1 shown in FIG. 1 includes a plurality of electric lock modules 2, an operation device 3, and a transmission unit 4.

[0023] The electric lock module 2 is provided on the door of a plurality of storage rooms that constitute a storage device such as a security box or a coin locker. The electric lock module 2 includes an opening / closing detection unit 21 that detects the opening and closing of the door, a locking / unlocking unit 22 that locks and unlocks the door, and an electric lock control unit 23 that controls the locking / unlocking of the locking / unlocking unit 22.

[0024] The opening / closing detection unit 21 is a sensor that detects the opening and closing of the door. The opening / closing detection unit 21 is, for example, a magnetic sensor (magnet sensor) in which the switch turns ON when the door opens, but it may also be a magnetic sensor in which the switch turns OFF when the door opens, or an optical sensor. It is not limited to this as long as it is a mechanism capable of detecting opening and closing.

[0025] The locking / unlocking unit 22 is an electric locking mechanism that closes the door. The locking / unlocking unit 22 may be an electric locking mechanism including a deadbolt that moves forward and backward between a locked position and an unlocked position, and a drive motor that drives the forward and backward movement of the deadbolt, and may further include a member such as a latch bolt that temporarily fastens the door.

[0026] The electric lock control unit 23 may be a control circuit that performs control processing for controlling the locking / unlocking unit 22. From the viewpoint of cost reduction, a control circuit composed of a single-ended type microcomputer is preferable. The electric lock control unit 23, for example, drives the drive motor based on an instruction signal transmitted from the operation device 3 described later to move the deadbolt from the unlocked position to the locked position, thereby causing the locking / unlocking unit 22 to lock the door.

[0027] The operation device 3 includes a reception unit 31 that receives a locking operation / unlocking operation for the electric lock module 2, and an information processing unit 32 that generates an instruction signal regarding locking / unlocking of a specific electric lock module 2 based on the operation information received by the reception unit 31 and the opening / closing detection information detected by the opening / closing detection unit 21, and transmits the instruction signal to the specific electric lock module 2.

[0028] The reception unit 31 is composed of, for example, a monitor and a plurality of hardware buttons, etc., and receives a locking operation / unlocking operation for which door is to be locked / unlocked. If the reception unit 31 can receive the selection of the door to be locked / unlocked, it may be a touch panel that also serves as an operation on and display for the electric lock module 2. When receiving the locking operation / unlocking operation, the reception unit 31 may be combined with an authentication configuration that can perform knowledge authentication such as input of an ID, password, PIN code, etc., possession authentication for reading an electronic key, contactless IC card, etc., biometric authentication for recognizing physical characteristics such as face and fingerprint, or multi-factor authentication that combines two or more of these authentications. Since the structure of the authentication configuration is an application of well-known technology, further explanation is omitted.

[0029] The information processing unit 32 is a circuit configuration capable of realizing information processing including at least an information acquisition unit 321, an information analysis unit 323, a signal generation unit 325, and a signal transmission unit 327. The information processing unit 32 may be any information processing circuit capable of realizing information processing. From the perspective of cost reduction, an information processing circuit composed of a single-ended microcomputer is preferable. The information acquisition unit 321 acquires the opening / closing detection information detected by the opening / closing detection unit 21 from the opening / closing detection unit 21, and acquires the operation information generated by the locking operation / unlocking operation received by the reception unit 31 from the reception unit 31. The information analysis unit 323 analyzes the opening / closing detection information to identify whether the door is open or closed, and analyzes the operation information to identify which electric lock module 2 provided on the door is to be locked / unlocked. The signal generation unit 325 generates an instruction signal for the electric lock module 2 identified by the information analysis unit 323. The signal transmission unit 327 transmits the instruction signal generated by the signal generation unit 325 to a specific electric lock module 2.

[0030] Alternatively, the reception unit 31 may be a reception device that wirelessly receives a locking operation / unlocking operation received by a mobile terminal such as a smartphone or a wireless terminal as operation information. In this case, the mobile terminal or the wireless terminal receives a locking operation / unlocking operation for which door is to be locked / unlocked, generates operation information, and transmits it to the reception unit 31 by various wireless communication methods such as wireless communication by electromagnetic waves such as Bluetooth (registered trademark), WiFi (registered trademark), ZigBee (registered trademark), NFC (Near Field Communication), infrared communication, and visible light communication.

[0031] The transmission unit 4 is composed of, for example, a connection wiring 41 and a connection port 42. The connection wiring 41 consists of input / output lines, power lines, and ground lines having a three-state configuration, preventing high impedance and enhancing noise resistance performance. The connection port 42 is provided with at least one each for the electric lock module 2 and the operation device 3, and can easily perform cascade connection between a plurality of electric lock modules 2 and the operation device 3. As shown in FIG. 1, the transmission unit 4 cascade-connects the information processing unit 32 included in the operation device 3 and the locking / unlocking control unit 23 included in any one of the plurality of electric lock modules 2, and cascades from the locking / unlocking control unit 23 to the locking / unlocking control units 23 of the other electric lock modules 2 one after another. Note that the electric lock system 1 preferably has a loop structure in which the locking / unlocking control unit 23 of the terminal electric lock module 2 is cascade-connected to the information processing unit 32, and each piece of information and instruction signal finally returns to the operation device 3 via a plurality of electric lock modules 2.

[0032] The transmission unit 4 transmits the opening / closing detection information, operation information, and instruction signal by electrically connecting between the operation device 3 and each electric lock module 2. The transmission speed at this time is a low speed of 10 Kbps or less, preferably 1 Kbps to 500 bps, and more preferably 400 bps or less. By setting the transmission speed to a low speed of 10 Kbps or less, not only power consumption can be reduced, but also the transmission of electrical signals in the control process of locking / unlocking the electric lock and the detection process of opening / closing the door can be stabilized.

[0033] Further, the transmission unit 4 may further include a wireless transceiver that wirelessly transmits and receives opening / closing detection information, operation information, and instruction signals between the operation device 3 and any one of the plurality of electric lock modules 2 or between the plurality of electric lock modules 2.

[0034] The storage device 100 shown in FIG. 2 will be described. FIG. 2 is a schematic diagram showing a storage device 100 composed of a plurality of storage chambers 10 in which the electric lock system 1 shown in FIG. 1 is implemented. The electric lock system 1 according to the present invention is implemented in the storage device 100.

[0035] The electric lock module 2 is provided for each door 101 of each storage chamber 10, and the locking / unlocking unit 22 further includes a door drive unit as means for changing the posture of the door 101 between a closed door posture and an open door posture. The operation device 3 is cascade-connected to the plurality of electric lock modules 2 and is incorporated in the storage device 100. The storage device 100 is connected to an external power source (not shown) in order to drive the plurality of electric lock modules 2 and the operation device 3. Further, the storage device 100 may be driven by a battery (not shown) provided inside the operation device 3 without being connected to an external power source.

[0036] The storage device 100 receives a locking operation / unlocking operation at the reception unit 31 of the operation device 3, and the electric lock module 2 locks / unlocks the door 101. In order to correspond to the locking operation / unlocking operation received at the reception unit 31, each door 101 and each electric lock module 2 are associated with each other. The storage device 100 does not perform the association between each door 101 and each electric lock module 2 in advance, and after the storage device 100 is installed, an association operation for associating each door 101 and each electric lock module 2 is performed.

[0037] The information processing unit 32 in the storage device 100 further includes an association setting unit 322 and an information storage unit 324. The association setting unit 322 associates each electric lock module 2 with each door 101 based on the opening / closing detection information. The information storage unit 324 stores the association information in which each electric lock module 2 and each door 101 are associated with each other. The information storage unit 324 may be implemented by a non-volatile storage device such as an HDD (Hard Disk Drive) or an SSD (Solid State Drive) separately from the information processing circuit of the information processing unit 32. From the perspective of cost reduction, it is preferable to implement it with a single-ended microcomputer that constitutes the information processing circuit.

[0038] The association operation is preferably distinguished from the normal operations of the storage device 100, such as the locking operation and unlocking operation of the electric lock module 2. If the normal operation and the association operation can be distinguished, a start button for starting the association operation may be provided separately from the reception unit 31, or the reception unit 31 may receive the association start operation for starting the association operation. Further, when the association operation is started by pressing the association button or receiving the association start operation of the reception unit 31, it is preferable to use the above-described authentication configuration to distinguish between the operations by general users and the operations by installers.

[0039] Regarding the association operation in the storage device 100, an example will be described in which the reception unit 31 receives the association start operation for starting the association operation. In the following, the door 101 may sometimes refer to including the storage room 10. FIG. 3 is a flowchart showing the association operation in the storage device 100 shown in FIG. 2.

[0040] The reception unit 31 receives an association start operation (step S31). When the information analysis unit 323 analyzes that the operation information acquired by the information acquisition unit 321 in the operation device 3 is an association start operation, the association setting unit 322 determines whether association information has been stored in the information storage unit 324 before receiving the association start operation (step S32). If the association information has already been stored in the information storage unit 324 (step S32 is Y), the association setting unit 322 initializes the information storage unit 324 (step S33), and the signal generation unit 325 generates an instruction signal to set the posture of all the doors 101 to the door-opening posture. The signal transmission unit 327 transmits the instruction signal to all the electric lock modules 2 (step S34). If the association information has not been stored in the information storage unit 324 (step S32 is N), the process proceeds directly to step S34. At this time, it is preferable that the association setting unit 322 knows how many electric lock modules 2 the signal transmission unit 327 has transmitted the instruction signal to.

[0041] When the electric lock module 2 provided on the door 101 acquires the instruction signal, regardless of the posture of the door 101, it drives the door drive unit included in the locking / unlocking unit 22 to change the posture of the door 101 to the door-opening posture. Note that the doors 101 may change their postures to the door-opening posture all at once, or may change their postures to the door-opening posture with a time difference.

[0042] For example, when manually changing the door 101 in the door-opening posture to the door-closing posture, the opening / closing detection unit 21 detects the closing of the door 101 (step S35). The association setting unit 322 associates the electric lock module 2 with the door 101 based on the opening / closing detection information of the door 101 detected by the opening / closing detection unit 21 (step S36). At this time, the electric lock module 2 and the door 101 are associated with each other using an identifier, for example, a room number. The room numbers are assigned in the order in which the doors 101 are closed.

[0043] The information storage unit 324 stores the association information associated by the association setting unit 322 (step S37). The information storage unit 324 stores the association information in which the electric lock module 2 and the door 101 are associated with each other using the room numbers assigned in the order in which the doors 101 are closed.

[0044] The related setting unit 322 determines whether all the electric lock modules 2 and the door 101 are associated with each other by room numbers (step S38). If all the electric lock modules 2 and the door 101 are not associated with each other (step S38 is N), the process returns to step S36 again and the implementation is repeated. If all the electric lock modules 2 and the door 101 are associated with each other (step S38 is Y), the association operation in the storage device 100 is completed.

[0045] Thereby, the storage device 100 only needs to change the door 101 in the open door position to the closed door position, and since the electric lock module 2 and the door 101 are associated with each other by identifiers, it is not necessary to preset the association between the electric lock module 2 and the door 101. The storage device 100 equipped with the electric lock system 1 according to the present invention does not need to perform a confirmation operation to check whether the electric lock module 2 and the door 101 are associated as preset after the storage device 100 is installed.

[0046] Also, even in the case of initial settings when the storage device 100 is installed for the first time, and even in the case of change settings such as changing the arrangement of the storage rooms 10 in the storage device 100 or increasing or decreasing the number of installed storage rooms 10, the information storage unit 324 is initialized every time the association operation is performed. For this reason, the association between the electric lock module 2 and the door 101 may be performed without checking the content stored in the information storage unit 324 before performing the association operation, and both the initial settings and the change settings of the storage device 100 can be performed with a simple operation.

[0047] Note that the association between the door 101 and the electric lock module 2 is triggered by the change of the door 101 from the open door position to the closed door position, but the change of the door 101 from the closed door position to the open door position may also be used as a trigger for associating the door 101 and the electric lock module 2 with each other.

[0048] In the storage device 100, the door 101 that was locked by the electric lock module 2 is unlocked by a normal operation, and the electric lock system 1 when the door 101 is opened will be described. FIG. 4 is a flowchart showing an example when the electric lock system 1 shown in FIG. 1 has the door opened by a normal operation.

[0049] Activate the operating device 3 (step S41). As an operation to activate the operating device 3, for example, pressing any one of the plurality of hardware buttons constituting the reception unit 31 or approval by authentication as described above can be mentioned. Thereby, the electric lock system 1 is activated.

[0050] Select the storage room 10 to be opened (step S42). The operating device 3 receives, at the reception unit 31, an operation to select the storage room 10 to be opened, for example, an input of the room number which is the position information of the storage room 10. At this time, the information processing unit 32 determines whether the door 101 has already been opened based on the opening / closing detection information detected by the opening / closing detection unit 21 in the door 101 of the input room number (step S43). If it has already been opened (step S43 is N), an error is displayed at the reception unit 31 of the operating device 3, or it is notified to input again, and the user is prompted to select the storage room 10 to be opened again. If it has not been opened (step S43 is Y), the information processing unit 32 transmits an instruction signal to unlock the electric lock module 2 provided on the door 101 of the storage room 10 corresponding to the room number to the storage room 10.

[0051] The electric lock module 2 acquires the instruction signal from the information processing unit 32 by the electric lock control unit 23, and based on the instruction signal, the electric lock module 2 provided on the door 101 of the storage room 10 is unlocked (step S44).

[0052] As a result of the locking / unlocking unit 22 being in the unlocked state, the door 101 is opened (step S45). The open / close detection unit 21 of the electric lock module 2 transmits the fact that the door 101 has been opened as open / close detection information to the operation device 3, and the process is completed. The above-mentioned operation is merely an example in which the door 101 is opened by normal operation, and even when the door 101 is locked by normal operation, the operation device 3 accepts the locking operation and the electric lock module 2 performs locking.

[0053] The electric lock system 1 may include a power control unit that goes into a hibernation state if no operation on the operating device 3 or opening / closing of the door 101 is detected for a certain period of time. The power control unit puts the electric lock modules 2 and the operating device 3 into a hibernation state while maintaining the locking and unlocking of the electric lock modules 2. Thereafter, when the power control unit detects an operation on the operating device 3 or the opening / closing of the door 101, it cancels the hibernation state and starts up the electric lock system 1.

[0054] Next, the electric lock system 1 will be described when the door 101, which has been locked by the electric lock module 2 in the storage equipment 100, is unlocked by an emergency operation and the door 101 is opened. Fig. 5 is a flow chart showing an example of the electric lock system 1 shown in Fig. 1 when the door is opened by an emergency operation.

[0055] The door 101 of the storage device 100 is opened (step S51). For example, when the door 101 of the storage device 100 is opened by an emergency operation such as forcing it open without operating the operation device 3, the open / close detection unit 21 detects that the door has been opened, and the electric lock module 2 and the operation device 3, which are in a dormant state, are started up.

[0056] In the electric lock module 2 of the opened door 101, the open / close detector 21 transmits the fact that the door 101 has been opened as open / close detection information to the operating device 3 (step S52).

[0057] When the operation device 3 acquires the opening / closing detection information, the information processing unit 32 determines whether the reception unit 31 has received the operation information for opening the door 101 before the door 101 is opened (step S53). If the reception unit 31 has received the operation information for opening the door 101 (step S53 is N), the process ends there. If the reception unit 31 has not received the operation information for opening the door 101 (step S53 is Y), the information processing unit 32 transmits the notification information including the room number (position information) and the time when the opening / closing detection information was acquired to the external device as the information indicating which door 101 was opened by the emergency operation around what time (step S54), and then ends.

[0058] The external device is, for example, the management server of the administrator who manages the storage device 100 or the mobile terminal of the user who uses the storage room 10. When the notification information is transmitted, the management server stores the notification information, or the mobile terminal displays the room number of the storage room 10 included in the notification information and the time when the door 101 was opened on a monitor or the like.

[0059] In the embodiment of the storage device 100 in which the electric lock system 1 described above is implemented, although the related setting unit 322 associates the electric lock module 2 with the door 101 based on the opening / closing of the door 101, in other embodiments, the association between the electric lock module 2 and the door 101 may be set in advance.

[0060] As described above, the embodiments of the present invention have been described. However, the present invention is not limited to such examples, and it goes without saying that the present invention can be implemented in various forms without departing from the gist of the present invention.

[0061] In addition, although the storage device 100 has been given as an example in which the electric lock system 1 is implemented, for example, it can also be applied to the case where an electric lock is provided for each door of each guest room in a hotel or the like.
