Description

  The present invention relates to an entry / exit system that allows entry and exit of a room having a substantially linear boundary.

  Conventionally, there is an entrance / exit system shown in FIG. 7 as a system in which a slide type automatic door is provided and only the authorized person opens the automatic door to allow entry / exit. This entrance / exit system 101A uses an IC card (not limited to a card shape) in which an RFID tag is incorporated for authentication, and an authorized person carries the IC card. If the RFID tag 10 is a so-called active type or semi-active type that incorporates a battery and emits radio waves by itself, the carrier of the IC card in which the RFID tag 10 is built holds the IC card over the reader. You can enter or leave the room hands-free without doing anything.

  As the RFID tag, a semi-active type is particularly advantageous. In this semi-active type, the trigger coil 104 that generates a magnetic field is embedded in the floor near the automatic door 50, and only in the activation area AA where the trigger coil 104 is activated. The RFID tag 10 located at is activated. Therefore, the authentication range is not too wide and is limited to a predetermined range from the automatic door 50. Then, the authentication apparatus 102 determines whether or not the RFID tag 10 in the activation area AA is recognized and authenticated and registered.

  In the entrance / exit system 101A, an outdoor object detection sensor 3A (3) and an indoor object detection sensor 3B (3) are attached to the outdoor side and the indoor side of the automatic door 50, respectively. These object detection sensors 3A and 3B detect human bodies in the detection areas CA and CB, respectively, and output an opening signal of the automatic door 50.

  Therefore, in the entrance / exit system 101A, when the authentication device 102 determines that the recognized RFID tag 10 is authenticated and registered, and any one of the object detection sensors 3 detects a human body in the detection area C, The automatic door 50 is opened.

  However, it is common to authenticate RFID tags carried by persons attempting to enter rooms at important entrances and exits of condominiums, but not to authenticate those who are leaving the room. . In order for the entrance / exit system 101A to cope with such a situation, it is necessary to install the trigger coil 104 outside the room as shown in FIG. However, if the activation area AA protrudes into the room, the RFID tag 10 that has been registered for authentication is recognized in the protruding portion, and a person who does not have the RFID tag that has been authenticated and registered outside the room is detected by the outdoor object detection sensor. Even if it enters the detection area CA of 3A, the automatic door 50 will be opened.

  In order to prevent this, it is also conceivable that the trigger coil 104 is further arranged on the outdoor side as shown in the top view of FIG. 9 to make the trigger coil 104A so that the activation area AA1 does not protrude into the room. However, in this case, when the user of the RFID tag 10 approaches the automatic door 50 along the wall 53 as indicated by the arrow D1, the RFID tag 10 does not enter the activation area AA1 and is not recognized. Even though the tag 10 is carried, the automatic door 50 is not opened.

  In addition to this, it is assumed that the activation area AA of the trigger coil 104 protrudes into the room, and accordingly, the detection area CB of the indoor object detection sensor 3B is set to be the detection area CB1 away from the automatic door 50, It is also conceivable that the activation area AA and the detection area CB1 do not overlap. However, in this case, the original function of the object detection sensor that detects an object near the trajectory of the automatic door 50 to ensure safety and opens the automatic door 50 only when the object approaches the automatic door 50 is achieved. Can't be achieved.

  On the other hand, there is a technology that can set the boundary between an area that recognizes an RFID tag and an area that is not recognized using a plurality of trigger units 104 in a substantially straight line, and this technology is used in various applications (for example, Patent Document 1).

JP 2013-037630 A

  Therefore, the present invention uses a technology that can set the boundary between the area that recognizes the RFID tag and the area that does not recognize it in a substantially straight line. An object of the present invention is to provide an entrance / exit system that can perform an appropriate authentication process without authenticating an exit while performing authentication.

  In order to achieve the above object, the present invention is an entry / exit system that allows entry and exit of a room having a substantially linear boundary, and detects an object in a first detection area outside the boundary in the vicinity of the boundary. A first object detection sensor that outputs an object detection signal when an object is detected, and a second object that detects an object in a second detection area in the room near the boundary and outputs an object detection signal when the object is detected. An object detection sensor, an authentication table for storing an identifier of an RFID tag registered in advance for authentication, and a first RFID tag that activates an RFID tag that is located in a first activation area outside the room, including the first detection area. An activation source; a second activation source for activating an RFID tag located in a second activation area in the room, adjacent to the first activation area at the boundary and including the second detection area; and An RFID signal transmitted by an RFID tag located in one activation area and in the second activation area, indicating an RFID tag identifier and whether the RFID tag is located in the first or second area An RFID reader that receives an RFID signal including an area identifier, an RFID tag recognition unit that recognizes only an RFID tag located in the first activation area based on the RFID signal received by the RFID reader, and the authentication table Referring to FIG. 4, an authentication determination unit that determines whether or not the RFID tag recognized by the RFID tag recognition unit is registered, and the authentication determination unit determines that at least one RFID tag is registered. An authentication output means for outputting an authentication signal when the authentication output means outputs an authentication signal, and Entry / exit permission means for permitting entry when the first object detection sensor outputs an object detection signal and permitting exit when the second object detection output means outputs an object detection signal. .

  Here, “entering” and “exiting” means entering / exiting a building or room, and “permitting entry / exiting” means permitting passage through the entrance of the building or room.

  The “first activation area including the first detection area” and the “second activation area including the second detection area” include the case where the detection area includes the entire detection area and the almost entire detection area. This applies to both cases where the activation area is included.

  “RFID tag pre-authenticated and registered” is an RFID tag built in an IC card or the like that is carried by a person who has the authority to enter the room, and is pre-registered as something to be authenticated by some operation That is.

  According to this configuration, since the first activation area and the second activation area are adjacent to each other at the indoor / outdoor boundary, the authentication area does not protrude into the room, and authentication is not performed outside the vicinity of the boundary. There is no area. Therefore, it is possible to properly authenticate only the entrance. In addition, since the objects in the indoor and outdoor areas near the boundary are detected by the object detection sensor, it is possible to appropriately detect a person who is going to enter and leave the room and permit entry and exit in combination with authentication.

  According to a preferred embodiment, an opening / closing means is provided at the opening of the boundary, and the entrance / exit permission means outputs an opening signal for opening the opening / closing means when permitting entry or exit. According to this, since the opening / closing means is closed unless entry / exit is permitted, entry / exit can be restricted. Although the authentication is not performed for leaving the room, the opening / closing means is not opened unless the second object detection sensor detects an object in the room near the opening / closing means, so that the opening / closing means can be prevented from being opened excessively. .

  According to a further preferred embodiment, the opening / closing means is a sliding automatic door.

  According to still another preferred embodiment, the opening / closing means is a shutter.

  Preferably, further, a first housing in which the first object detection sensor and the first activation source are arranged, and a second object detection sensor and the second activation source are arranged. At least one of the second housings is provided. Thereby, since an object detection sensor and a starting source are accommodated in a single housing | casing, handling is easy and it is excellent in workability.

  According to the entrance / exit system of the present invention, by using a technique that can set the boundary between the area that recognizes the RFID tag and the area that does not recognize it in a substantially straight line, in the indoor / outdoor room having a substantially straight boundary, Appropriate authentication processing can be performed without authentication for entering the room but authenticating for leaving the room.

It is a side view which shows the entrance / exit system in the case where the conventional entrance / exit system authenticates only entrance and its peripheral area. It is a top view along the IX-IX line of FIG.

Hereinafter, an entrance / exit system according to an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 shows an entrance / exit system 1 according to the first embodiment of the present invention and its authentication area A and detection areas CA and CB. The entrance / exit system 1 of the present invention permits entry and exit of a building 6 having an entrance (opening) 54 provided with a sliding automatic door (opening / closing means) 50 by opening the automatic door 50. The entrance / exit of the building 6 is, for example, an important entrance / exit in a company building or an apartment entrance / exit.

  The entrance / exit system 1 includes a main body device 2 attached to a peripheral wall (not shown in FIG. 1) of a slide type automatic door 50, an inner surface of a seamless 51 that supports an upper end portion of the automatic door 50, and Object detection sensors 3 and 3 attached to the outer side surfaces, respectively. Here, the object detection sensor 3 attached to the outer surface of the invisible eye 51 is an outdoor object detection sensor (first object detection sensor) 3A, and the object detection sensor 3 attached to the outer surface is an indoor object detection sensor. This is a sensor (second object detection sensor) 3B. The control unit 55 for the automatic door 50 is also accommodated in the invisible eye 51. The object detection sensors 3 and 3 may be provided on the ceiling 52 instead of the invisible eye 51.

  As shown in FIG. 2, the entrance / exit system 1 also includes first magnetic field generation means (first activation source) 4A that generates a trigger magnetic field that constitutes an outdoor activation area (outdoor first activation area) A. (Magnetic field generating means 4), second magnetic field generating means (second starting source) 4B (magnetic field generating means 4) for generating a trigger magnetic field constituting an indoor starting area (second starting area in the room) B, and And an RFID reader 5. The first and second magnetic field generating means 4A and 4B respectively include first and second trigger coils 4Aa and 4Ba, and first and second trigger units 4Ab that generate magnetic fields in the trigger coils 4Aa and 4Ba, respectively. , 4Bbb. The first and second trigger coils 4 </ b> Aa and 4 </ b> Ba are embedded in, for example, the outdoor and indoor floors near the door 50, respectively. The first and second trigger units 4Ab and 4Bbb are attached to the outer surface (outside surface) and the inner surface (inside surface) of the wall 53, respectively, and the first and second trigger coils are respectively connected by wires not shown. 4Aa and 4Ba are connected.

  In the present embodiment, the magnetic fields formed by the first and second magnetic field generating means 4A and 4B partially overlap. The RFID tag 10 entering the overlapped portion is activated by the magnetic field generating means 4A and 4B having the larger magnetic field strength. However, in this embodiment, the magnitudes of the magnetic fields generated by the first and second magnetic field generating means 4A and 4B are substantially the same, and the boundary between the first and second activation areas A and B is the door 50, and The linear shape extends along the door 50 and substantially coincides with a wall 53 that separates the outside from the room.

  The RFID tag 10 used in the present embodiment is a so-called semi-active type and incorporates a battery, but is activated by a trigger magnetic field formed by the magnetic field generating means 4A and 4B. Therefore, the RFID tag 10 is activated only when it is located in the activation areas A and B, and transmits an RFID signal (radio wave).

  The RFID reader 5 includes an antenna, and receives RFID signals (radio waves) from the RFID tags 10 in the outdoor activation area A and the indoor activation area B. A plurality of RFID tags 10 can be located in the activation areas A and B. The RFID signals periodically transmitted from the plurality of RFID tags 10 in the activation areas A and B correspond to the tag ID unique to each RFID tag 10 and the magnetic field generating means 4A and 4B that activated the RFID tag 10. And an activation area ID indicating in which activation area A or B the activation area ID is included.

  As shown in FIG. 3, the main unit 2 includes an authentication table 21, an RFID tag recognition unit 22, an authentication determination unit 23, an authentication output unit 24, and an entrance / exit permission unit 25.

  The authentication table 21 stores tag IDs of RFID tags that have been registered for authentication. Here, the “authentication-registered RFID tag” means an RFID tag built in an object to be authenticated such as an IC card carried by a person having a so-called authority who is allowed to enter the building 6 (FIG. 1). That is, the tag ID is stored in the authentication table 21 at the time of authentication registration.

  The RFID tag recognition means 22 recognizes all RFID tags located in the outdoor activation area A of FIG. 2 based on the RFID signal received by the RFID reader 5. On the other hand, the RFID tag located in the indoor activation area B is not recognized. This is because authentication is performed for entry, but authentication is not performed for exit. Thus, the outdoor activation area A becomes a recognition area, but the indoor activation area B does not become a recognition area.

  The authentication determination unit 23 in FIG. 3 determines whether or not all RFID tags recognized by the RFID tag recognition unit 22 are authenticated and registered with reference to the authentication table 21. The authentication output unit 24 outputs an authentication signal when the authentication determination unit 23 determines that at least one RFID tag is registered for authentication.

  Main device 2 also includes an entry / exit permission means 25. The entrance / exit permission means 25 is connected to a control device 55 of a door engine (not shown) and outputs an instruction signal to open the automatic door 50 to the control device 55 when the passage is permitted.

  Returning to FIG. 1, the object detection sensors 3 </ b> A and 3 </ b> B attached to the inner side surface and the outer side surface of the invisible eye 51 are substantially the same and symmetrical with respect to the automatic door 50. Only the object detection sensor 3 will be described.

  The object detection sensor 3 is composed of, for example, an AIR (active infrared system) sensor. The object detection sensor 3 projects near-infrared light, which is a kind of detection wave for object detection, toward the detection area C (first outdoor detection area CA or second indoor detection area CB). And a light receiver 32 that receives a detection wave reflected by the object and generates a light reception signal. A lens (not shown) is provided on the front surface of each of the projector 31 and the light receiver 32, and a detection area C (FIG. 1) is formed in a direction downward from the mounting position and away from the automatic door 50. The object detection sensor 3 further includes an object detection output means 35. In the detection area C, the amount of light received by the light receiver 32, that is, the amount of light received with reference to the amount of light received when no object exists in the detection area C, is detected. It is determined that an object has been detected, and an object detection signal is output. The two object detection sensors 3A and 3B are connected to the main body device 2. The indoor object detection sensor 3B may be connected to the control device 55 instead of the main body device 2.

  An authentication signal output from the authentication output unit 24 and detection signals output from the detection determination units 35 of the two object detection sensors 3 and 3 are input to the entrance / exit permission unit 25 of the main body device 2. The entrance / exit permission means 25 permits the passage of the object detected by the object detection sensor 3A or 3B based on the authentication signal and the detection signal. The main body device 2 is connected to the control device 55. The control device 55 controls a door engine (not shown) to open or close the automatic door 50. When the indoor object detection sensor 3B is connected to the control device 55 instead of the main body device 2, the indoor object detection sensor 3B substantially permits the passage of the object detected by the indoor object detection sensor 3B. This is a detection output means 35.

Next, the process of the passage permission means 41 of the entrance / exit system 1 will be described with reference to the flowchart of FIG.
In step S1, it is determined whether a detection signal is input from the indoor object detection sensor 3B (FIG. 1). When no indoor detection signal is input (No in step S1), it is determined in step S2 whether an authentication signal is input. If no authentication signal is input (No in step S2), the process returns to step S1. If there is an authentication signal input (Yes in step S2), it is determined in step S3 whether or not a detection signal from the outdoor object detection sensor 3A (FIG. 1) has been input. When there is no outdoor detection signal input (No in step S3), the process returns to step S1. When there is an input of an outdoor detection signal (Yes in Step S3), an opening instruction signal is output to the control device 55 so as to open the automatic door 50 (Step S4).

  As described above, when the indoor object detection sensor 3B in FIG. 1 detects an object (Yes in step S1 in FIG. 4), an opening instruction signal is output unconditionally (step S4 in FIG. 4). This is because no authentication is required for leaving the room. On the other hand, for entering the room, the RFID tag in the outdoor activation area A is authenticated (Yes in step S2 in FIG. 4), and the outdoor object detection sensor 3A detects an object (Yes in step S3 in FIG. 4). In this case, an open signal is output. As described above, it is necessary to detect an object for entering a room in addition to authentication. This is particularly effective when the outdoor activation area A is greatly expanded in the direction away from the automatic door 50. That is, even if the person who carries the RFID tag 10 that has been registered for authentication enters the outdoor activation area A, the automatic door 50 is not opened unless it enters the outdoor detection area CA. The automatic door 50 is accidentally opened when the person is not going to enter the room, or the automatic door 50 is opened even if the person carrying the RFID tag 10 that is registered for authentication is away from the automatic door 50. Can be prevented.

  When the indoor object detection sensor 3B is connected to the control device 55 instead of the main body device 2, it is determined whether or not a detection signal is input from the indoor object detection sensor 3B (step S1 in FIG. 4). ) And outputting the opening instruction signal in accordance with this determination (step S4 in FIG. 4) are substantially executed by the detection output means 35 in the indoor object detection sensor 3B. The processing executed by the detection output means 35 is executed independently of the processing executed by the entrance / exit permission means 25 of the main body device 2 (steps S2 to S4 in FIG. 4).

  In an application form outside the scope of the present invention, either one or both of the outdoor object detection sensor 3A and the indoor object detection sensor 3B may be omitted. For example, when both the outdoor object detection sensor 3A and the indoor object detection sensor 3B are not provided and the opening means 50 is a manual door, the key is unlocked by the authentication of the RFID tag 10 for entering the room, For leaving the room, the human body may touch the handle of the door and the key may be unlocked.

  An entry / exit system according to a second embodiment of the present invention will be described. The system according to this embodiment is different from the entrance / exit system according to the first embodiment shown in FIG. 1 in the configuration of the object detection sensor and the activation means. Constituent elements common to the system according to the present embodiment and the system according to the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

  As shown in FIG. 5, the entrance / exit system 1 </ b> A includes entrance / exit devices 7, 7 attached to an invisible inner side surface and an outer side surface. Here, the entrance / exit device 7 attached to the outer side surface of the seamless 51 is an outer entrance / exit device 7A, and the entrance / exit device 7 attached to the inner side is an inner entrance / exit device 7B. These entrance / exit devices 7A and 7B are respectively composed of a single casing 7a and 7a (first casing 7Aa and second casing 7Ba). Since these entrance / exit devices 7 and 7 are substantially the same and symmetrical with respect to the automatic door 50, only one entrance / exit device 7 will be described below.

  The entrance / exit device 7 includes the object detection sensor 3 and the magnetic field generation means 4, which are housed in a housing 7a. As in the first embodiment, the object detection sensor 3 is composed of, for example, an AIR (active infrared type) sensor, and is disposed below the magnetic field generation unit 4 in the entrance / exit device 7 attached to the eyeless 51. The In this embodiment, the magnetic field generating means 4 is composed of a permanent magnet. However, it may be composed of a trigger coil and a trigger unit as in the first embodiment.

  In this embodiment, since the magnetic field generating means 4 is attached to the invisible 51, the installation area is completely different from that of the first embodiment in which the trigger coil is embedded in the floor, but the ranges of the activation areas A and B are strictly set. Therefore, there is no problem even if the installation location of the magnetic field generating means 4 is insignificant 51. In particular, as long as the magnetic field generating means 4 is arranged symmetrically about the automatic door 50, the boundary between the outdoor activation area A and the indoor activation area B can be made substantially coincident with the boundary between the indoor and outdoor areas. There is no need to strictly adjust the installation location of the trigger coil 104 (FIG. 7) in order to limit the activation area outside the room, as in the case of performing the authentication in the above. Therefore, the entrance / exit device 7 may be installed according to the object detection sensor 3. That is, the entrance / exit device 7 is installed considering only the point where the object detection sensor 3 is suitable for detecting an object near the automatic door 50.

  In the entrance / exit device 7, since the object detection sensor 3 and the magnetic field generating means 4 are accommodated in a single casing 7a, the handling is easy and the workability is excellent.

  In the present embodiment, the object detection sensor 3 and the magnetic field generation means 4 are housed in the single casing 7a both outdoors and indoors. It consists of a single casing 7a, and the object detection sensor 3 and the magnetic field generation means 4 may be separate on the other side.

  As described above, according to the entrance / exit system according to the present invention, a room having a substantially linear boundary can be obtained by using a technique that can set the boundary between an area that recognizes an RFID tag and an area that is not recognized to be almost linear. In an outside entrance / exit, it is possible to perform an appropriate authentication process without performing authentication for entering the room but performing authentication for leaving the room.

  In each of the above embodiments, the object detection sensor 3 is composed of an AIR (active infrared) sensor. However, the object detection sensor 3 may be an object detection sensor that can detect an object passing through the automatic door 50 and entering or leaving the room. Anything can be used. For example, a PIR (passive infrared) sensor or an ultrasonic sensor may be used.

  In each of the above embodiments, the opening / closing means 50 (FIGS. 1 and 5) has been described as a sliding automatic door. However, the opening / closing means is not limited to a sliding automatic door, and responds to object detection. Any device may be used as long as it operates and permits entry or exit of the room having a linear boundary. The opening / closing means may be a shutter, for example, a sheet shutter that opens and closes an opening of a building using a flexible thin sheet body. In addition, the opening / closing means may be a slide-type manual door, a swing-type manual door that swings outdoors or indoors, or a swing-type automatic door that swings outdoors or indoors.

  Next, an entrance / exit system according to one application mode that does not fall within the scope of the present invention will be described. Constituent elements common to the system according to the first and / or second embodiment in the system according to this application mode are denoted by the same reference numerals and description thereof is omitted.

  FIG. 6 is a top view of the entrance / exit system 1B according to this application mode. The entrance / exit system 1B includes entering and exiting a building 6 having entrances / exits (openings) 54A, 54B constituted by a cylindrical door frame 55 provided with sliding curved automatic doors 50A, 50B. Allow by 50B. Here, when entry is not permitted, passage of the outer automatic door 50A is not permitted.

  In this application mode, the boundary D between the activation areas A and B respectively formed by two magnetic field generating means (not shown) does not coincide with the automatic door 50A.

  On the other hand, in the entrance / exit system 1B, two outdoor object detection sensors 3A1, 3A2 and two indoor object detection sensors 3B1, 3B2 are provided, and outdoor detection areas CA1, CA2 and indoor detection areas CB1, CB2, respectively. Is formed.

  According to this application mode, as described above, the boundary D between the activation areas A and B does not coincide with the automatic door 50A. Therefore, when the RFID tag 10 that has been authenticated and registered is located in an area portion E indicated by hatching in the outdoor activation area A that is a recognition area, which protrudes to the indoor side, it is recognized by an RFID tag recognition means (not shown). However, the carrier of the RFID tag 10 cannot enter the area portion E unless it passes through the indoor detection area CB1 of the indoor object detection sensor 3B1. Therefore, even if the RFID tag 10 in the activation area A is recognized, the automatic door 50A is not opened if the indoor object detection sensor 3B1 detects an object. As a result, it is possible to perform authentication for entering the room but not for exiting the room.
