Description

  The present invention relates to a doorway opening / closing device for a building provided with a human sensor.

  Conventionally, an apparatus that automatically opens and closes a door using an electronic key has been proposed (for example, Patent Document 1). In such an apparatus, an authentication unit and a human sensor are provided on both the outdoor side and the indoor side.

  For example, when a person passes through an entrance / exit provided with the apparatus, the door is automatically opened by the person performing an authentication operation using the authentication means. And when the door is opened, both the outdoor side and indoor side human sensors are in a non-detection state, and thus the door is automatically closed. In such a door opening / closing device, there is no trouble of taking out the key, and the door can be opened and closed without using a hand, so that the convenience of the user is improved.

JP 2014-222943 A

  However, in the above conventional door opening and closing device, when a person passes through the doorway, the door remains open by the detection of the human sensor at the back of the passage, even though the person has passed through the doorway. There is a risk of becoming. For example, if the area between the entrance doors on the indoor side of the entrance door is included in the detection range of the human sensor, the human sensor will continue to detect humans when people take off their shoes, and the door will be open during that time. End up. That is, the door open state is unnecessarily maintained. Therefore, there is still room for improvement from the viewpoint of usability and crime prevention.

  The present invention has been made to solve the above-described problems, and has as its main object to provide a doorway opening / closing device for a building that can appropriately perform opening / closing control of the opening / closing body in accordance with the movement of a person. .

  The first invention includes an opening / closing body provided at an entrance / exit that allows a person inside and outside to enter and exit, a drive unit that automatically opens / closes the opening / closing body, and an indoor side and an outdoor side across the opening / closing body. An authentication means for authenticating a person who passes through the entrance and exit, and provided on the indoor side and the outdoor side across the opening and closing body, and detects the presence of a person with a predetermined range including the entrance and exit as a detection range A person detecting means; and an opening / closing control means for opening the opening / closing body during a period in which the presence of a person is detected by the person detecting means when authentication is performed by the authentication means. The control means, when a person passes through the entrance / exit, enables the person detecting means on the indoor side and the outdoor side authenticated by the authenticating means, invalidates the person detecting means on the opposite side, and Detection by the human detection means Which comprises carrying out the opening and closing control of the opening and closing member based on the results.

  In the above configuration, since the authentication means and the person detection means are provided on both the indoor side and the outdoor side of the entrance / exit, the opening / closing body is automatically opened / closed both when the person enters the room and when the person goes outside. It is possible. In addition, when a person passes the doorway, the person detection means on the authenticated side of the indoor side and the outdoor side is valid and the person detection means on the opposite side is invalid. The opening / closing body is closed regardless of the detection result of the human detection means on the back side. That is, it is possible to prevent the opening / closing body from being left open for a while by the human detection means on the back side even though the person has passed the entrance / exit. Moreover, crime prevention can be ensured by closing the opening and closing body. As described above, the opening / closing control of the opening / closing body can be appropriately performed according to the movement of the person.

  The second invention is characterized in that the detection ranges of the human detection means overlap each other in a region including the entrance / exit.

  In the above configuration, since the detection ranges of the human detection unit overlap each other in the region including the entrance / exit, it is possible to prevent the inconvenience that the opening / closing body is closed before the person has passed through the entrance / exit. Therefore, the opening / closing timing of the opening / closing body can be optimized.

  According to a third aspect of the present invention, the opening / closing control means opens and closes the opening / closing body after a predetermined time has elapsed since the detection of the person by the effective person detecting means was not detected when the person passed through the doorway. Control is performed.

  In the above configuration, since the opening / closing body is closed after a predetermined time has elapsed since the detection of the person by the effective human detection means is not detected, the opening / closing body is closed before the person finishes passing through the doorway. Can be prevented. Therefore, the opening / closing timing of the opening / closing body can also be optimized.

  According to a fourth aspect of the present invention, the opening / closing body is a hinged door that opens to either the indoor side or the outdoor side, and the predetermined time is a human detection means that is effective when a person passes through the doorway However, when the hinged door is on the opposite side to the side on which the hinged door is opened, it is set longer than when it is on the same side.

  When the opening / closing body is a hinged door, there is an opening / closing area associated with the movement of the opening / closing body. Considering this point, in the above configuration, when the effective human detection means is on the opposite side to the side where the hinged door is opened, the person can open and close by setting a predetermined time longer than that on the same side. The opening / closing body can be closed in consideration of the time passing through the region. Thereby, the opening / closing timing of a hinged door can be optimized.

  According to a fifth aspect of the present invention, the opening / closing body is a hinged door that opens with respect to either the indoor side or the outdoor side, and the person detection means on the side opposite to the side on which the hinged door opens opens and closes the hinged door. The presence of a person is detected using a predetermined range including an open / close region for detection as a detection range.

  In the above configuration, the person detecting means on the side opposite to the side on which the hinged door is opened detects the presence of a person with a predetermined range including an opening / closing area for opening and closing the hinged door as a detection range. In this case, it is possible to close the open / close body after grasping that there is no person in the open / close region. Thereby, the opening / closing timing of the hinged door can also be optimized.

  According to a sixth aspect of the present invention, the opening / closing body includes a locking member that can be locked and unlocked, and includes a locking control unit that performs locking control of the locking member, and the locking control unit is configured by the opening / closing control unit. The opening / closing body is closed and the opening / closing body is locked.

  In the above configuration, since the opening / closing body has the locking member, and the opening / closing body is closed and the opening / closing body is locked, it is possible to suppress the indoor intrusion by the suspicious person or the like. Thereby, the improvement of crime prevention is realizable.

(First embodiment)
DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, an embodiment of the invention will be described with reference to the drawings. In the present embodiment, an opening / closing device that performs opening / closing control of an opening / closing body provided at an entrance of a building is embodied. The structure of this apparatus is shown in the schematic diagram of FIG.1 and FIG.2.

  As shown in FIGS. 1 and 2, a building 10 such as a house is provided with an entrance 11. The entrance 11 has an entrance soil 12 and an entrance hall 13 as a space for taking off and putting on shoes such as shoes. An entrance / exit 15 is formed in the outer wall 14 that partitions the entrance 11 (indoor space) and the outdoor space, and the entrance / exit 15 communicates the indoor space and the outdoor space. The entrance door 15 is provided with an entrance door 16 as an opening / closing body. The front door 16 is a sliding type sliding door, and has a motor 17 as a drive unit at the upper part of the side surface. The motor 17 is electrically connected to the door controller 31 and opens and closes the entrance door 16 in accordance with a control signal from the door controller 31.

  The entrance door 16 is provided with a handle 18 and a well-known cylinder lock 19. The cylinder lock 19 is electrically connected to the door controller 31, and locks and unlocks the entrance door 16 in accordance with a control signal from the door controller 31. The cylinder lock 19 may be provided not on the entrance door 16 side but on the outer wall 14 side.

  Face authentication devices 21a and 21b as user authentication systems are provided on the outdoor side and the indoor side of the outer wall 14 with the entrance door 16 in between. The face authentication device 21 includes an authentication control device (not shown) composed of a computer having a CPU, RAM, ROM, and the like, and a camera (not shown). When a user's face is photographed by the camera, the face image is input from the camera to the authentication control apparatus. The authentication control device includes a storage unit and an authentication unit, and user face information is stored (registered) in advance as a registered face image in the storage unit. The authentication unit performs authentication processing of a face image input from the camera. Specifically, the authentication unit determines whether the face image input from the camera matches the registered face image stored in the storage unit. Then, the signal output by this authentication process is input to the door controller 31.

  In addition, human sensors 22a and 22b that detect the presence of a person are installed on the outdoor side and the indoor side of the outer wall 14 with the entrance door 16 in between, and these are respectively provided on the outer wall 14 above the entrance door 16. Is provided. The human sensor 22 is configured to detect the presence of a person by detecting a temperature change within a detection range using infrared rays or the like. When the presence sensor 22 detects the presence of a person within the detection range, a signal indicating a detection state is input from the presence sensor 22 to the door controller 31.

  The front door 16 is provided with a door opening / closing sensor 23. The door open / close sensor 23 detects the open / closed state of the front door 16, and the detection signal is input to the door controller 31.

  The door controller 31 includes a known microcomputer including a CPU, ROM, RAM, and the like. The door controller 31 performs opening / closing control of the entrance door 16 based on signals output from the face authentication device 21, the human sensor 22, and the door opening / closing sensor 23. Specifically, when an authentication signal indicating that the user has been authenticated is input by the face authentication device 21, the door controller 31 opens the entrance door 16 by driving the motor 17. When the front door 16 is opened, the open state of the front door 16 is maintained during a period when a detection signal indicating the presence of a person is input by the human sensor 22. When the detection signal is not input by the human sensor 22 in the opened state of the entrance door 16, the entrance door 16 is closed because there is no more person. The door controller 31 controls the locking and unlocking of the cylinder lock 19 when the entrance door 16 is opened and closed.

  By the way, in the conventional authentication type opening / closing device, the door is opened based on the authentication by the authentication device, while the human sensor 22 provided on the outdoor side and the indoor side is in a non-detection state. The door is closed. That is, after a person passes through the entrance 15, the door is automatically closed on condition that there is no person in the vicinity.

  On the other hand, in such an opening / closing device, when a person passes through the entrance / exit 15, the door remains open by the detection of the human sensor 22 on the far side of the passage, even though the person has finished passing. Become. Details will be described with reference to FIG. FIG. 3 shows the detection range X1 of the outdoor human sensor 22a by a one-dot chain line and the detection range X2 of the indoor human sensor 22b by a broken line (hereinafter shown in FIGS. 5, 7, 9, and 10). The same applies to the detection range). FIG. 3 assumes a scene in which the user U enters the room through the entrance door 16. The indoor-side human sensor 22b mainly sets the detection space X2 between the entrance soil 12 and the position of the user U shown in FIG. 3 falls within the detection range X2. Therefore, for example, when the user U takes off his shoes in the front door 12, it is detected by the human sensor 22 b while taking off his shoes, and the front door 16 is in the open state. In such a case, it is considered undesirable from the viewpoint of privacy and crime prevention. Therefore, it is desirable that the entrance door 16 is closed in accordance with the movement of the person.

  Therefore, in this embodiment, the door controller 31 enables the human sensor 22 on the side authenticated by the face authentication device 21 among the indoor side and the outdoor side when the person passes through the entrance 15, and the human side on the opposite side. The sensor 22 is disabled and the entrance door 16 is controlled to be closed based on the detection result of the enabled human sensor 22.

  Specifically, when a person moves indoors from the outdoors, the outdoor face authentication device 21a authenticates so that the outdoor human sensor 22a is valid and the indoor human sensor 22b is invalid. It becomes. That is, in this case, even if a person exists within the detection range X2 of the human sensor 22b, the human sensor 22b detects the person but does not output a detection signal to the door controller 31. As a result, the door controller 31 controls to close the door based on the detection result of only the human sensor 22a. Specifically, when the human sensor 22a shifts from the detection state to the non-detection state, it is assumed that a person has passed, and the entrance door 16 is controlled to be closed.

  Here, the detection range of the human sensor 22 is set as appropriate. In the present embodiment, the detection ranges X1 and X2 of the human sensors 22a and 22b are set to include the entrance / exit 15. Specifically, the detection ranges X1 and X2 of the human sensors 22a and 22b overlap each other in a region including the entrance 15. In the present embodiment, the human sensors 22a and 22b are always activated.

  Next, the opening / closing control executed by the door controller 31 will be described with reference to the flowchart of FIG. This process is executed at a predetermined time period.

  In FIG. 4, in step S11, it is determined whether or not the door is in a closed state. Here, the determination is made based on the detection result of the door opening / closing sensor 23. If step S11 is YES, the process proceeds to step S12, and if step S11 is NO, the process proceeds to step S21. In step S12, it is determined whether any of the human sensors 22a and 22b detects the presence of a person. If step S12 is YES, the process proceeds to step S13, and if step S12 is NO, it is determined that there is no person in the vicinity of the entrance door 16, and the process is terminated.

  In step S13, it is determined whether or not the face authentication device 21 has authenticated a person. If step S13 is YES, it will progress to step S14 and the cylinder lock 19 will be unlocked. In the subsequent step S15, the entrance door 16 is opened by driving the motor 17. On the other hand, if step S13 is NO, this process is ended as it is. That is, the door is not opened because the person is different from the person registered in advance.

  In step S16, it is determined whether or not the person authentication by the face authentication device 21 is authentication by the outdoor face authentication device 21a. If step S16 is YES, it will progress to step S17 and will invalidate the indoor side human sensitive sensor 22b. On the other hand, if step S16 is NO, that is, if authentication is performed by the indoor face authentication device 21b, the process proceeds to step S18, and the outdoor human sensor 22a is invalidated. That is, in this case, the human sensor 22 on the opposite side to the authenticated side is invalidated. Thereby, only the human sensor 22 on the authenticated side becomes effective.

  On the other hand, when the door is in the open state (step S11: NO), the process proceeds to step S21, in which one of the effective human sensors 22a and 22b has shifted from the detection state to the non-detection state. judge. If step S21 is YES, the process proceeds to step S22. In step S22, it is determined whether or not a predetermined time T has elapsed since one of the human sensors 22a and 22b has shifted to the non-detection state. Here, a predetermined time T is provided as a grace period until the door is closed after the human sensor 22 is in the non-detection state. For example, the user may be surprised if the door is suddenly closed immediately after the user has passed. Therefore, such inconvenience is reduced by providing the predetermined time T. The predetermined time T is, for example, about 1 to 5 seconds.

  The predetermined time T may be changed as appropriate. For example, when the outdoor human sensor 22a shifts from the detection state to the non-detection state, and when the indoor human sensor 22b changes from the detection state to the non-detection state. It is good also as a structure which provides a difference in predetermined time T by the case where it transfers. In other words, the timing at which the entrance door 16 closes can be adjusted depending on whether the user moves indoors to outdoors or when the users move indoors to outdoors. Thereby, it can adapt according to a user's use mode etc.

  Then, when the predetermined time T has elapsed after the human sensor 22 shifts to the non-detection state (step S22: YES), the process proceeds to step S23, the entrance door 16 is closed, and then the cylinder lock 19 is locked. (Step S24). In step S25, the invalid human sensor 22 is canceled.

  On the other hand, if step S21 is NO, this process is ended as it is. That is, when the human sensor 22 is in the detection state, the door is kept open.

Next, the manner of opening / closing control of the front door 16 will be described with reference to FIGS. here,
(1) A scene that the outdoor face authentication device 21a authenticates,
(2) A scene where the indoor face authentication device 21b authenticates after the outdoor face authentication device 21a authenticates,
Each scene will be described. Among these, FIGS. 5 and 7 show the relationship between the movement of the user U when passing through the doorway 15 and the detection ranges X1 and X2 of the human sensor 22. 6 and 8 show timing charts corresponding to FIGS. 5 and 7, respectively.

  First, FIGS. 5 and 6 show scenes that are authenticated by the outdoor face authentication device 21a. That is, the scene where the user U moves indoors from the outdoors is assumed. First, at time t11, when the user U enters the detection range X1 of the outdoor human sensor 22a, the human sensor 22a enters a detection state. Thereafter, when the outdoor face authentication device 21a authenticates the user U at timing t12, the entrance door 16 is opened. As a result, when the user U passes through the doorway and the user U moves outside the detection range X1 of the human sensor 22a at the timing t13, the human sensor 22a enters a non-detection state. Then, the door is closed at a timing t14 after a predetermined time T has elapsed since the non-detection state.

  In this case, when the outdoor face authentication device 21a authenticates, the indoor human sensor 22b becomes invalid. Therefore, although the indoor human sensor 22 b detects the user U, the detection signal is not output to the door controller 31. Thereby, in the conventional opening / closing control, the user U moves outside the detection range X2 of the human sensor 22b, that is, the entrance door 16 is opened until the timing t15 when the human sensor 22b is in a non-detection state. In this control, the entrance door 16 can be closed in accordance with the movement of the user U.

  5 and 6 assume a scene in which one user moves indoors from the outdoors, but door opening / closing control is performed in the same manner when, for example, a plurality of users enter indoors continuously. In such a case, the entrance door 16 is closed based on the detection result of the human sensor 22a on the outdoor side.

  Next, FIGS. 7 and 8 show a scene in which another user is authenticated on the indoor side after the entrance door 16 is opened by human authentication on the outdoor side. That is, it is assumed that one user UA moves from the outdoors to the indoors and the other user UB moves from the indoors to the outdoors. First, the user UA is detected by the human sensor 22a (timing t21), and authenticated by the face authentication device 21a, the entrance door 16 is opened (timing t22). At this time, the human sensor 22b is invalid. Thereafter, if the user UB is authenticated by the indoor face authentication device 21b at the timing t31 within a period in which the user UA is detected by the human sensor 22a, the indoor human sensor 22b becomes effective and the user UB is detected.

  When the user UA passes through the entrance / exit 15 at timing t23, the human sensor 22a enters a non-detection state. At this time, since the human sensor 22b on the indoor side is in the detection state, the entrance door 16 is kept open. When the user UB moves outside the detection range X2 of the human sensor 22b at timing t32, the human sensor 22b enters a non-detection state, and then the door is closed after a predetermined time T has elapsed (timing t33). As described above, in the case where the authentication is continuously performed on both the outdoor side and the indoor side, the human sensors 22a and 22b on both the outdoor side and the indoor side are validated.

  According to the embodiment described in detail above, the following excellent effects can be obtained.

  In the above configuration, since the face authentication devices 21a and 21b and the human sensors 22a and 22b are provided on both the outdoor side and the indoor side of the entrance / exit 15, either the person enters the indoor or the person goes outside. The automatic opening / closing of the opening / closing body is also possible. In addition, when a person passes through the doorway 15, one of the indoor side and outdoor side authenticated human sensors 22a and 22b is effective, and one of the reverse human sensors 22a and 22b Since it becomes invalid, after a person passes through the entrance 15, the entrance door 16 is closed regardless of the detection result of the presence sensors 22 a and 22 b on the back side. That is, it is possible to prevent the entrance door 16 from being left open for a while by any one of the human sensors 22a and 22b on the back side even though the person has passed through the entrance / exit 15. Moreover, crime prevention can be ensured by closing the entrance door 16. As described above, the opening / closing control of the front door 16 can be appropriately performed according to the movement of the person.

  Specifically, since the detection ranges of the human sensors 22a and 22b overlap each other in the region including the entrance 15, the opening / closing body is closed before the person finishes passing through the entrance 15. Can be prevented. Therefore, the opening / closing timing of the front door 16 can be optimized.

  Furthermore, since the entrance door 16 is closed after a predetermined time has elapsed since the detection of the person by any one of the effective human sensors 22a and 22b is not detected, the entrance door 16 is closed before the person has passed the entrance / exit 15. Can be avoided. Therefore, the opening / closing timing of the entrance door 16 can be optimized.

  In addition, the entrance door 16 has a cylinder lock 19, and the entrance door 16 is closed and the entrance door 16 is locked, so that it is possible to suppress indoor intrusion by a suspicious person or the like. Thereby, the improvement of crime prevention is realizable.

(Second Embodiment)
Next, the second embodiment will be described focusing on the differences from the first embodiment. In the second embodiment, the entrance door 16 is configured as a hinged door that opens to either the outdoor side or the indoor side instead of the sliding sliding door. Here, in the case of a hinged door, there is an open / close region associated with the movement of the door, unlike the case of a sliding door. In such a case, it is desirable that the door be closed with no person in the open / close region.

  In 2nd Embodiment, it controls so that the entrance door 16 may be closed in consideration of the opening / closing area | region of a hinged door. Specifically, the detection range of the human sensor 22 on the side opposite to the side where the hinged door opens (that is, the side where the open / close region is generated) is configured to include the open / close region. Details will be described with reference to FIG.

  In FIG. 9, the entrance door 41 which is a hinged door opened with respect to the outdoor side is shown. In addition, above the entrance door 41, human sensors 22a and 22b are provided on the outdoor side and the indoor side, respectively. In this case, the detection range X1 of the human sensor 22a is set to include the entrance / exit 15, whereas the detection range X2 of the human sensor 22b is set to include the opening / closing region of the entrance door 41. ing. In other words, the detection range X2 is set so that the opposite side region (for example, the outdoor region in the case of the human sensor 22b) can be detected in a wider range than the detection range X1.

  In this configuration, for example, when the user U moves from indoors to outdoors, only the human sensor 22b is effective by authentication of the face authentication device 21b on the indoor side. In this case, since the detection range X2 of the human sensor 22b is set so as to include the opening / closing area of the entrance door 41, it is possible to close the entrance door 41 after grasping that there is no person in the opening / closing area. it can.

  On the other hand, as other opening / closing control considering the opening / closing area of the hinged door, the predetermined time T may be different depending on the opening / closing area. Specifically, when the human sensor 22 on the side opposite to the side where the hinged door opens (that is, the side where the open / close region is generated) is effective, the human sensor 22 on the same side as the side where the hinged door opens is effective. Compared with the case where it becomes, it is set as the structure which makes predetermined time T longer. Details will be described with reference to FIGS. 10 and 11.

  10 and 11 show a scene in which the user U moves from indoor to outdoor with respect to the entrance door 41 that opens toward the outdoor side. That is, in this case, the entrance door 41 opens on the opposite side (that is, the outdoor side) to the human sensor 22b that is enabled by the indoor face authentication device 21b. When the user U is detected by the human sensor 22b (timing t41) and authenticated by the face authentication device 21b, the entrance door 41 is opened (timing t42). When the user U moves outside the detection range X2 of the human sensor 22b at timing t43, the human sensor 22b enters a non-detection state, and then the door is closed after a predetermined time TA has elapsed (timing t44). Here, the predetermined time TA is set longer than the predetermined time TB set when the outdoor face authentication device 21a is authenticated. Therefore, the position of the user U corresponding to the timing t44 does not interfere with the opening / closing area of the front door 41. Thereby, the entrance door 41 can be closed according to the movement of the user U. Even in this case, since the human sensor 22a on the outdoor side is disabled, no detection signal is output even if the user U is detected.

  As mentioned above, according to these structures, even if the entrance door 41 is a case of a hinged door, the entrance door 41 can be closed in consideration of the time for a person to pass through the open / close region. Thereby, the opening / closing timing of a hinged door can be optimized.

  The present invention is not limited to the description of the above embodiment, and may be implemented as follows, for example.

  In the above embodiment, the control for invalidating the human sensor 22 is configured to invalidate the detection signal detected by the human sensor 22, but the present invention is not limited to this, and the detection itself of the human sensor 22 is stopped. Thus, the human sensor 22 may be invalidated.

  In the above embodiment, the face authentication device 21 is used as the authentication system, but the present invention is not limited to this, and other authentication systems may be used. For example, a fingerprint authentication device or a voice authentication device can be used. In this case, these devices are electrically connected to the door controller 31 and output an authentication processing signal to the door controller 31.

  In the above embodiment, the door controller 31 is applied to the entrance doors 16 and 41 of the building 10, but may be applied to other doors in the building 10, for example, doors provided at the entrance.
