[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2004-339702 Summary of the Invention [Problem to be solved by the invention]

[0004] In interlock control, when one unlocked door is locked, the other door can be unlocked. However, if a user attempting to unlock a door cannot see the door located at a distance, they cannot determine when the door they are trying to open has transitioned from a prohibited state to an unlockable state. In this case, the user must try to unlock the door to check whether the door has transitioned to an unlockable state, which reduces the usability of the access control system. [Means for solving the problem]

[0005] The present disclosure provides an access control system that includes a control device that detects the closing and opening of each door provided at a pair of entrances to a space, and an alarm unit that corresponds to each door and issues an alarm under the control of the control device, wherein when one of the doors is opened, the control device issues an alarm via the alarm unit corresponding to the other door, and when one of the doors is closed, the control device stops the alarm via the alarm unit corresponding to the other door.

[0006] The present disclosure provides an access control method using a control device that detects the closing and opening of doors provided at a pair of entrances to a space, wherein each door is provided with an alarm unit that issues an alarm under the control of the control device, and when one of the doors is opened, the control device issues an alarm using the alarm unit corresponding to the other door, and when the opened door is closed, the control device stops the alarm using the alarm unit corresponding to the other door. [Effects of the Invention]

[0007] According to the present invention, the usability of the access control system can be improved. [Brief explanation of the drawings]

[0008] [Figure 1] FIG. 1 is a front view of an embodiment of a door controlled by an access control system. [Figure 2] 2 is a schematic diagram showing the main parts of a building managed by the access control system of the embodiment. FIG. [Figure 3] 10 is a flowchart illustrating the procedure of the entry / exit management method according to the embodiment. [Figure 4] 1 is a schematic diagram showing the main parts of a building managed by the access control system of the embodiment, showing a state in which one door body is open. FIG. DETAILED DESCRIPTION OF THE INVENTION

[0009] An embodiment of an access control system and an access control method will be described below. 1 shows the main part of the front of a door body 11 provided at a doorway 17. The door 1 has a door frame structure 10 (hereinafter referred to as the frame structure 10) and the door body 11.

[0010] The access control system includes a control device 24 (see FIG. 2) that detects the closing and opening of each door 1 provided at each of a plurality of entrances 17, and a light-emitting unit 15 that corresponds to each door 1 and is a notification unit that issues a notification under the control of the control device 24. When one door 1 is opened, the control device 24 issues a notification using the light-emitting unit 15 corresponding to the other door 1, and when one door 1 is closed, the control device 24 stops the notification using the light-emitting unit 15 corresponding to the other door 1. In this embodiment, the doors 1 are locked and unlocked by an electronic lock as closed and open by the control device 24. "Closed" includes a locked state, and "open" includes an unlocked state.

[0011] When the door 1 is unlockable and user authentication by the authentication device 14 is successful, the door 1 is unlocked by an electric lock (not shown), and is locked after the door body 11 is closed. The door 1 is also interlocked with the other door 1 that forms a pair (first linkage). When one door 1 is unlocked by interlock control, the other door 1 is not unlocked. The door body 11 is not limited to an opening and closing type. For example, the door body 11 may be a single door as exemplified in FIG. 1, or may be a pair of doors rotatably supported on each side end of the frame structure 10, a sliding door, a folding door, a hanging door, or the like.

[0012] A frame structure 10 is provided on a wall 16 (see FIG. 2). The frame structure 10 defines an entrance / exit 17. The frame structure 10 includes a frame portion 12, a light-emitting portion 15, hinges (not shown) that rotatably support the door body 11, an electric lock (not shown), and the like.

[0013] The light-emitting unit 15 is provided corresponding to each door 1A, 1B (see FIG. 2). The light-emitting unit 15 is housed in the frame 12. The light-emitting unit 15 is exposed through an opening formed in the front face 13 of the frame 12. The light-emitting unit 15 is provided at a position that matches the eye level of the user (for example, 140 cm to 160 cm). The light-emitting unit 15 has a light source provided in the frame 12 and a control circuit that turns the light source on and off (both not shown). The light-emitting unit 15 corresponds to an alarm unit that provides an alarm as a second linkage for the door 1 supported by the frame structure 10 in which the light-emitting unit 15 is provided.

[0014] 1 shows a state in which the light-emitting unit 15 is lit. The light-emitting unit 15 emits a colored light such as red, or a white light. The lighting of the light-emitting unit 15 notifies that unlocking is prohibited by interlock control. When the light-emitting unit 15 is lit, the door 1 is locked, and will not be unlocked even if the user authentication by the authentication device 14 is successful.

[0015] The extinguishing of the light emitting unit 15 indicates that it is possible to unlock the door main body 11. In this state, the door 1 is locked, but will be unlocked if the authentication device 14 successfully authenticates the user.

[0016] (Access control system) An example in which the entry / exit control system 20 is applied to a building that requires sanitary control, such as a clean room or a factory, will be described with reference to FIGS.

[0017] 2 is a plan view showing a schematic diagram of the main parts of a building. Clean rooms, factories, etc. are zoned to separate rooms according to cleanliness classes. An anteroom 21 may be provided between an area 22 with a high cleanliness class and an area 23 with a low cleanliness class. The anteroom 21 is, for example, a changing room where workers entering area 22, etc., can change into clean wear.

[0018] Doors 1A and 1B are provided in the front room 21. Door 1A is located between the front room 21 and an area 22 with a high cleanliness class. Door 1B is located between the front room 21 and an area 23 with a low cleanliness class. Entry and exit to the front room 21 is managed by an access control system 20.

[0019] The entry / exit management system 20 includes a control device 24, door control units 25A and 25B, authentication devices 14A and 14B, and light-emitting units 15A and 15B. The light-emitting units 15A and 15B are the light-emitting unit 15 described above. The door 1A is controlled by the door control unit 25A. The authentication device 14A and the light-emitting unit 15A are provided near the door 1A. The door 1B is controlled by the door control unit 25B. The authentication device 14B and the light-emitting unit 15B are provided near the door 1B.

[0020] The authentication devices 14A and 14B are devices that authenticate the user 31. For example, the authentication devices 14A and 14B are devices equipped with a card reader, a biometric authentication device that authenticates the face, iris, fingerprint, etc. of the user 31, or a numeric keypad for inputting a PIN. The authentication devices 14A and 14B output the authentication results to the door control units 25A and 25B. The door control units 25A and 25B drive electric lock mechanisms that have solenoids, electric motors, etc.

[0021] The control device 24 detects the closing and opening of each door 1 provided at each of the multiple entrances 17. In this embodiment, the control device 24 is electrically connected to the door control units 25A, 25B and the light-emitting unit 15, and detects the locking and unlocking of each door 1A, 1B provided at each of the multiple entrances 17 and controls the light-emitting unit 15. The control device 24 includes a processor such as a CPU, MPU, or NPU, a storage device (computer-readable medium), and a communication device. The processor may be configured as one of the following:

[0022] [1] One or more processors that operate according to a computer program (software). [2] One or more dedicated hardware circuits that perform at least some of the various processes [3] Circuits containing combinations of these The operation of the entry / exit control system 20 will be described.

[0023] 2 shows a state in which both doors 1A and 1B are locked. The control device 24 keeps the light-emitting unit 15A corresponding to the door main body 11A and the light-emitting unit 15B corresponding to the door main body 11B in an off state. At this time, either user 31A or 31B who is inside or outside the front room 21 can unlock the door main bodies 11A and 11B.

[0024] Fig. 3 shows the procedure for entry and exit management by the control device 24. For convenience of explanation, Fig. 3 illustrates the door 1 to be unlocked as door 1A and the door 1 to be prohibited from being unlocked as door 1B, but door 1A can also be prohibited from being unlocked by unlocking door 1B.

[0025] The control device 24 determines whether or not it has detected the unlocking of one of the doors 1 (step S1). For example, when one of the doors 1A is unlocked by the user 31A, the control device 24 receives an unlock signal from the door control unit 25A.

[0026] When the control device 24 detects that one door 1 has been unlocked (step S1: YES), it prohibits the unlocking of the other door 1 (step S2). Specifically, the control device 24 transmits an unlock prohibition signal, which is a command prohibiting unlocking, to the door control unit 25B. Upon receiving the unlock prohibition signal, the door control unit 25B keeps the door 1B locked regardless of the authentication result of the authentication device 14B. Therefore, the user 31B cannot open the door main body 11B even if the user authentication by the authentication device 14B is successful.

[0027] Furthermore, the control device 24 turns on the light emitting unit 15B of the door 1 that is prohibited from being unlocked (step S3). Specifically, the control device 24 transmits an ON signal to the control circuit of the light emitting unit 15B to the door control unit 25B to turn on the light emitting unit 15B.

[0028] 4, the control circuit of the light-emitting unit 15B turns on the light source when it receives an ON signal. As a result, even if the user 31B outside the front room 21 cannot see the unlocked door 1A, if the user 31B understands in advance the meaning of the illumination of the light-emitting unit 15B, he or she can understand that the reason door 1B cannot be unlocked is due to interlock control.

[0029] 3, the control device 24 determines whether or not the locking of the unlocked door 1A has been detected (step S4). Specifically, when the door 1A is locked, the control device 24 receives a lock signal from the door control unit 25A, thereby determining that the locking of the door 1A has been detected (step S4: YES).

[0030] When door 1A is locked, the control device 24 permits the unlocking of the other door 1 (step S5). At this time, the control device 24 transmits an unlock permission signal, which is a command to unlock door 1B, to the door control unit 25B. Upon receiving the unlock permission signal, the door control unit 25B puts door main body 11B into an unlockable state.

[0031] The control device 24 turns off the light-emitting unit 15B of the other door 1 that was lit (step S6). At this time, the control device 24 sends an OFF signal to the control circuit of the light-emitting unit 15B. The control circuit of the light-emitting unit 15B turns off the lit light source. This allows the user 31B to know when the door main body 11A, which the user cannot see, is locked and the door main body 11B that the user 31B is trying to open can be unlocked.

[0032] Similarly, the control device 24 also controls the light-emitting unit 15 of the door 1A. That is, when the door 1B is unlocked, the control device 24 prohibits the door 1A from being unlocked and turns on the light-emitting unit 15A corresponding to the door 1A. Furthermore, when the door 1B is locked, the control device 24 permits the door 1A to be unlocked and turns off the light-emitting unit 15A corresponding to the door 1A.

[0033] <Effects of this embodiment> As described above, according to the above embodiment, the following effects can be obtained. (1) When one door 1 is unlocked (opened), the control device 24 issues a notification that unlocking is prohibited by the light-emitting unit 15 corresponding to the other door 1, and when one door 1 is locked (closed), the control device 24 stops the notification that unlocking is prohibited by the light-emitting unit 15. This allows the user 31 to know the timing when the door 1 can be unlocked (opened).

[0034] (2) The light-emitting unit 15 is provided on the visible surface 13 of the frame 12 that supports each door 1 so that it can be opened and closed. Therefore, the user 31 can intuitively understand that the light-emitting unit 15 is a device that notifies the user of the state of the door 1.

[0035] <Example of change> The above-described embodiment can be modified as follows: Each embodiment and the following modifications can be combined with each other to the extent that no technical contradiction occurs.

[0036] (Other access control) The control device 24 may not perform interlock control and may only illuminate the light-emitting unit 15. In such a case, it is considered that simultaneously opening both door bodies 11A and 11B is undesirable, but performing interlock control would significantly reduce convenience. For example, the front room 21 and the areas 22 and 23 do not require a significantly higher level of cleanliness, but maintaining a certain level of cleanliness or higher is preferable. In this case, the control device 24 does not perform interlock control, and when one door 1A is unlocked, it illuminates the light-emitting unit 15B corresponding to the other door 1B. Furthermore, when the unlocked door 1A is locked, the control device 24 extinguishes the illuminated light-emitting unit 15B. Furthermore, when the door 1B is unlocked and locked, the control device 24 similarly controls the illumination and extinguishing of the light-emitting unit 15A corresponding to door 1A. This allows the user 31 to be warned not to open the doors 1A and 1B simultaneously.

[0037] Furthermore, the access control system 20 may detect the closing and opening (opening and closing) of the door main body 11 instead of detecting locking and unlocking. In this case, the door control units 25A and 25B detect the opening and closing of the door main body 11A and 11B, respectively. "Open" refers to a state in which the door main body 11 has moved from a closed position that closes the entranceway 17, and "closed" refers to a state in which the door main body 11 is located in the closed position. The closing and opening can be detected by various detection devices, such as an optical sensor or a magnetic sensor, provided on or near the door main body 11. When one door main body 11A is opened, the control unit 24 lights up the light-emitting unit 15B corresponding to the other door main body 11B, and vice versa.

[0038] In the above embodiment, the notification unit is the light-emitting unit 15. Alternatively or additionally, the notification unit may be something other than the light-emitting unit 15. For example, the notification unit may be a warning sound output device (buzzer, speaker) that outputs a warning sound or warning voice, or a display control device such as a display that displays a warning image. In this case, when one door main body 11A is unlocked, the control device 24 outputs a warning sound indicating that unlocking is prohibited from the warning sound output device corresponding to the other door main body 11B, and when one door main body 11A is locked, the control device 24 stops outputting the warning sound.

[0039] That is, the entry / exit control system 20 can perform any of the following in parallel with the interlock control: alert by the light-emitting unit 15, alert by the warning sound output device, or alert by both of these. Also, as described above, the entry / exit control system 20 can perform any of the above alerts without executing the interlock control.

[0040] In the above embodiment, the entry / exit control system 20 is applied to a pair of door bodies 11A and 11B, but it may also be used to control the entry / exit of three or more door bodies 11.

[0041] (Light emitting part) In the above embodiment, the light emitting unit 15 is provided on the front side (the surface shown in FIG. 1) of the door body 11. Alternatively or additionally, the light emitting unit 15 may be provided on the back side of the door body 11. For example, if the light emitting units 15 are provided on both the front side and the back side of the door body 11, the user 31 can know that the door body 11 is kept in the unlocking prohibited state no matter where the user 31 is.

[0042] In the above embodiment, the light-emitting unit 15 is provided on a portion of the visible surface 13 of the frame 12, but the light-emitting unit 15 may be provided on the entire visible surface 13, and the size and shape of the light-emitting unit 15 are not particularly limited. For example, the height of the light-emitting unit 15 may be the same as the height of the door body 11. The light-emitting unit 15 may also be provided on a portion of the frame 12 that extends horizontally. Furthermore, the light-emitting unit 15 may be provided in a frame shape that surrounds the door body 11.

[0043] In the above embodiment, the light-emitting unit 15 is provided on the frame 12, but the position of the light-emitting unit 15 is not particularly limited as long as the user 31 can understand the correspondence between the light-emitting unit 15 and the door main body 11. For example, the light-emitting unit 15 may be provided on the door main body 11 or the wall 16.

[0044] In the above embodiment, the access control system 20 is installed in a building that requires sanitation management, such as a clean room or a factory. Alternatively, the access control system 20 may be installed in a building that requires security, etc. Alternatively, the access control system 20 (locking / unlocking control system) may be installed in other objects, such as home appliances or vehicles.
