As described above, the door control device according to the present invention can appropriately control the operation of the door so that a suspicious person is not confined together with a legitimate person by being brought together in a predetermined space.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  The system to which the door control device according to the first embodiment of the present invention is applied is configured as shown in FIG. The door control device in this system controls the operation of elevator doors (including car doors and landing doors).

  In FIG. 1, reader devices 31 and 32 for reading an identification ID from an IC card held by a user are installed in the vicinity of an elevator door of the elevator hall. An IC card storing ID information for identifying the person is distributed in advance to those who are allowed to use the elevator. In the elevator car 40, an operation panel 42 having operation buttons for opening / closing the elevator doors 41a and 41b, designating the number of floors, and the like is installed, and a camera device 45 is installed on the ceiling thereof. The door control device 10 includes a user database in which ID information of a person who is permitted to use the elevator is registered. The ID information read from the IC card by the reader devices 31 and 32 and the camera device 45 A control signal related to the operation of the elevator doors 41a and 41b is generated based on the captured image of the space in the passenger car 40 and is supplied to the door driving device 20. The door drive device 20 drives the elevator doors 41 a and 41 b based on a control signal from the door control device 10 and an operation signal based on an operation on the operation panel 42 installed in the car 40.

  In the system configured as described above, the door control device 10 performs processing in accordance with the procedure shown in FIGS.

  In FIG. 2, the door control device 10 determines whether or not the door open conditions for the elevator doors 41a and 41b are satisfied (S1). The door open condition determination process is performed, for example, according to the procedure shown in FIG. This process will be described later. When the door control device 10 determines that the door open condition is satisfied (YES in S1), the door control device 10 outputs a door open control signal (S2). With this control signal, the door drive device 20 drives the elevator doors 41a and 41b to open.

  When the elevator doors 41a and 41b are thus opened, the door control device 10 determines whether the door closing conditions for the doors 41a and 41b are satisfied (S3), Whether or not ID information is sent is determined (NO in S3, S4). For example, it is determined as the door closing condition that a predetermined time has passed without the operation of the door closing button on the operation panel 42 from the door opening, or that the door closing button has been operated on the operation panel 42.

  When the user U1 who possesses the IC card enters the car 40, when the reader device 31 reads the identification ID by wireless communication with the IC card, the reader device 31 sends the ID information to the door control device 10. . When the door control device 10 determines that the ID information has been sent from the reader device 31 (YES in S4), the door control device 10 acquires the ID information (S5), and the ID information that matches the acquired ID information is It is determined whether it is registered in the user database (S6). If it is determined that ID information that matches the acquired ID information is registered in the user database (YES in S6), that is, authentication that the user is a regular user is performed. Then, the door control device 10 increments a counter K (initial value K = 0) for counting the number of authenticated users by +1 (S7).

  Thereafter, the door control device 10 determines whether or not the ID information is sent from any one of the reader devices 31 and 32 while determining whether or not the door closing condition is satisfied again (S3) (S4). ). In the process, when the ID information read from the IC card possessed by the user is sent from either of the reader devices 31 and 32 (YES in S4), the ID information is used based on the ID information as described above. Authentication is performed (S5, S6). Then, when the authentication of the authorized user is made (YES in S6), the door control device 10 increments the count value (the number of authenticated users) of the counter K by +1 (S7).

  Thereafter, the door control device 10 repeatedly executes the same processing as described above (S3 to S7). In the process, if it is determined that the ID information matching the ID information sent from either of the reader devices 31 and 32 is not registered in the user database (NO in S6), the door control device 10 Then, a warning message is displayed and a warning sound is output on an alarm unit (not shown, may be the reader devices 31 and 32) (S8). In this case, the counter K is not incremented. As a result, the count value of the counter K accurately represents the number of users who have been authenticated as authorized users (the number of authenticated users).

  In the process described above, for example, when any of the users who have entered the car 40 operates the door closing button of the operation panel 42, the door control device 10 determines that the door closing condition is satisfied (S3). YES) Then, the door control device 10 acquires a captured image of the space in the car 40 from the camera device 45, and calculates the number of users who have boarded the car 40 from the captured image, that is, the number N of actual users. Detect (S9). For example, an image portion corresponding to the user's head can be cut out from the photographed image, and the number of the image portions can be set to the number N of actual users.

  The door control device 10 determines whether or not the count value (authentication user number K) of the counter K matches the actual user number N (S10). If it is determined that the number of authenticated users K and the actual number of users N match (YES in S10), all users who have entered the car 40 have been authenticated as being legitimate users. The door control device 10 outputs a door close control signal (S11). By this control signal, the door drive device 20 is driven to close the elevator doors 41a and 41b in the open state. The elevator car 40 is driven in accordance with normal operation control.

  After outputting the door close control signal, the door control device 10 resets the counter K (K = 0) (S12) and returns to the initial state (S1).

  For example, in FIG. 1, when a suspicious person Ux who does not have an IC card enters the car 40 together with a user U1 who has an IC card, the suspicious person Ux is not counted as a regular user. On the other hand, the number N of actual users detected based on the captured image from the camera device 45 includes the number (+1) of the suspicious persons Ux. Therefore, it is determined that the number of authenticated users K and the actual number of users N do not match in the process described above (NO in S10). In this case, the door control device 10 further confirms that the number of authenticated users K is smaller than the actual number of users N (NO in S13), and outputs a door close prohibition control signal to the door drive device 20. (S14). As a result, the door driving device 20 does not drive the elevator doors 41a and 41b even if any of the users who have entered the car 40 operates the door closing button of the operation panel 42 as described above. Therefore, the elevator car 40 is not in a closed room. For example, the door control device 10 determines whether or not a reset button provided on the operation panel 42 has been operated (S16), and generates a buzzer sound from a buzzer (not shown) installed in the car 40. (S15).

  The legitimate user U1 can determine that the user Ux who rides with the buzzer sound is a suspicious person, and can quickly leave the elevator car 40. Moreover, the state which can confirm the mode in the passenger car 40 is also maintained from the elevator landing side.

  When the reset button provided on the operation panel 42 is operated (YES in S16), the door control device 10 outputs a door close control signal to the door drive device 20. The elevator doors 41a and 41b are closed by the control of the door driving device 20 based on this control signal. The door control device 10 returns to the initial state (S1) after resetting the counter K (S12).

  By the way, if ID information is read from any one of the reader devices 31 and 32 from an IC card possessed by a legitimate user and the user decides to get on the elevator car 40, authentication is used. The number K of users is smaller than the number N of actual users. In this case, after the door control device 10 determines that the number of authenticated users K and the number of actual users N do not match (NO in S10), the number of authenticated users K is greater than the number of actual users N. It determines with it being large (it is YES at S13). In this case, the door control device 10 outputs a door close control signal on the assumption that all the users (actual users) who have boarded the car 40 are authorized users (S11). ).

  As described above, according to the door control device 10 that controls the operation of the elevator doors 41a and 41b, the actual user obtained when the elevator doors 41a and 41b are opened and the user enters the elevator car 40. If the number N is equal to the number of authenticated users K, or if the number of authenticated users K is larger than the number of actual users N, the elevator doors 41a and 41b are allowed to close. Thereby, when all the users in the elevator car 40 are regular users, the opened elevator doors 41a and 41b are closed. On the other hand, if the actual user number N does not match the authenticated user number K and the authenticated user number K is smaller than the actual user number N, the elevator doors 41a and 41b are prohibited from being closed. As a result, when a suspicious person enters the car 40 together with a legitimate user, the elevator doors 41a and 41b are not closed, and the legitimate user is confined in the car 40 together with the suspicious person. Is prevented.

  In the above-described processing, it is determined whether or not the actual user number N and the authenticated user number K match (S10), and whether or not the authenticated user number K is larger than the actual user number N. The determination (S14) is a separate processing step, but these processing steps are integrated to determine whether the number of authenticated users K is equal to or greater than the number N of actual users, or the number of actual users. It is also possible to determine whether N is equal to or less than the number of authenticated users K.

  The door open condition determination process (S1 in FIG. 2) will be described. This process is performed according to the procedure shown in FIG.

  In FIG. 3, the door control device 10 is in a waiting state for ID information from the reader devices 31 and 32 (S101). When the user who possesses the IC card comes to the vicinity of the elevator doors 41a and 41b in the closed state, one of the reader devices 31 and 32 reads the ID information from the IC card and sends the ID information to the door control device 10. . As described above, when the door control device 10 waiting for the ID information determines that the ID information has been sent from either the reader device 31 or 32 (YES in S101), the door control device 10 acquires the ID information. (S102), it is determined whether or not ID information that matches the acquired ID information is registered in the user database (S103). If it is determined that the ID information that matches the acquired ID information is registered in the user database (YES in S103), that is, the user is authenticated as a legitimate user. Then, the door control device 10 determines whether or not a call operation of the car 40 (for example, an operation of an upward or downward button) is performed (S104).

  When the call operation of the car 40 is performed by the user (YES in S104), the door control unit 10 controls the elevator call to register the car call indicating that the car 40 is called at the landing. It transmits to a system (not shown) (S105). Thereafter, the door control unit 10 determines whether or not the car 40 has arrived at the landing (S107). When the car 40 arrives at the landing (YES in S107), the door control unit 10 determines whether the elevator doors 41a and 41b are It is determined that the door open condition is satisfied (YES in S1).

  In the process described above, when it is determined that ID information that matches the acquired ID information is not registered in the user database (NO in S103), the door control device 10 outputs a warning (S106). ), The process returns to the initial state (S101). That is, if the user is not an authorized user who has registered ID information in advance, the calling operation of the elevator car 40 is not effective, and the elevator doors 41a and 41b cannot be opened.

  Thus, by requesting user authentication for the opening control of the elevator doors 41a and 41b, the operation control of the elevator doors 41a and 41b with higher security can be performed.

  Note that the door open condition determination process (S1) is not limited to the process in the above-described procedure. As with normal elevator operation, the call operation of the car 40 is performed without requiring user authentication, and then it is determined that the door opening condition is satisfied when the elevator car 40 arrives at the landing. You can also In this case, the opening of the elevator doors 41a and 41b is controlled in the same way as a normal elevator, and the control as described above (see FIG. 2) is performed for the closing.

  In the door control device according to the first embodiment described above, the ID information used for user authentication is provided from the IC card. However, this user identification information and the providing method thereof are as follows. It is not limited to this. It is possible to use biometric information such as iris, fingerprint, and voiceprint as user identification information and provide the biometric information to the door control device 10 from a dedicated reading device. In this case, the user's biometric information is registered in advance in the user database. It is also possible to provide the ID information to the door control device 10 via the keyboard device.

  Next, a door control device according to a second embodiment of the present invention will be described. The system to which the door control device according to the second embodiment of the present invention is applied is configured as shown in FIG. The door control device in this system controls the operation of two doors provided at two entrances / exits in one space.

  In FIG. 4, for example, first doors 81a and 81b are provided at a first entrance / exit of a waiting room 80 provided adjacent to a specified living room where security management is performed, and the boundary between the waiting room 80 and the specified living room is Second doors 82a and 82b are provided at the second entrance / exit. A reader device 70 is installed in the vicinity of the first doors 81 a and 81 b outside the standby chamber 80, and a camera device 85 is installed on the ceiling of the standby chamber 80. An IC card storing ID information identifying the person is distributed in advance to those who are allowed to enter and leave the specific room.

  The door control device 50 includes a user database in which ID information of persons permitted to enter and exit the specific room is registered. The ID information read from the IC card by the reader device 70 and the camera device 85 Based on the captured image of the space in the waiting room 80, control signals relating to the operation of the first doors 81a and 81b and the second doors 82a and 82b are generated and supplied to the door driving device 60. The door drive device 60 drives the first doors 81a and 81b and the second doors 82a and 82b based on a control signal from the door control device 50.

  In the system described above, the door control device 50 performs processing according to the procedure shown in FIGS.

  In FIG. 5, the door control device 50 is waiting for the ID information from the reader device 70 (S21). When the person who has the IC card comes in the vicinity of the closed first doors 81a and 81b, the reader device 70 reads the ID information from the IC card and sends the ID information to the door control device 50. As described above, when the door control device 50 in the ID information waiting state determines that the ID information is sent from the reader device 70 (YES in S21), the ID information is acquired (S22). It is determined whether or not ID information that matches the acquired ID information is registered in the user database (S23). If it is determined that ID information that matches the acquired ID information is registered in the user database (YES in S23), that is, the person who has arrived at the first doors 81a and 81b is an authorized person. If authentication is made, the door control device 50 increments the count value of the counter K (the number of authenticated users K) by +1 (S24).

  Thereafter, the door control device 50 starts a timer and repeatedly determines whether or not a predetermined waiting time has elapsed (S25) and whether or not ID information has been sent from the reader device 70 (S26). In the process, the door control device 50 determines that the ID information read from the IC card held by another person has been sent from the reader device 70 before the waiting time has elapsed (NO in S25). (YES in S26), the ID information is acquired (S22), and it is determined whether or not the ID information matching the ID information is registered in the user database (S23). When it is determined that ID information that matches the acquired ID information is registered in the user database (YES in S23), the door control device 50 counts the count value of the counter K (authentication user). The number is further incremented by +1 (S24).

  On the other hand, when the waiting time elapses without acquiring new ID information (YES in S25), the door control device 50 outputs a control signal for opening the first door (S27). The door driving device 60 drives the first doors 81a and 81b based on the control signal, thereby opening the first doors 81a and 81b as shown in FIG.

  When the door control device 50 determines that the ID information that matches the ID information acquired from the reader device 70 is not registered in the user database in the course of the above-described process (NO in S23), a warning is output. (S28), a warning message is displayed on a display device (not shown), and an alarm sound is output from the alarm device. In this case, the first doors 81a and 81b are not opened.

  When the first doors 81a and 81b are opened as described above, the person who has the IC card can enter the waiting room 80 as shown in FIG. And the door control apparatus 50 progresses to the process in the procedure shown in FIG.

  In FIG. 6, the door control device 10 acquires a captured image of the space in the standby room 80 from the camera 85 and detects the number of persons entering the standby room 80 from the captured image, that is, the number N of actual users. (S31). The actual number of users N can be detected in the same manner as in the first embodiment described above. Thereafter, the door control device 10 determines whether or not the count value of the counter K (the number of authenticated users K) matches the number of actual users (S32). For example, as shown in FIGS. 7 and 8, when the authenticated person U1 enters the waiting room 80 alone, the number of authenticated users K = 1 matches the number of actual users N = 1 (in S32). YES), the door control device 50 outputs a control signal for the first door close and outputs a control signal for the second door opening, assuming that all persons who have entered the waiting room 80 are authorized persons. (S33, S34). Based on these control signals, the door driving device 60 drives the first door 81a, 81b and the second door 82a, 82b, thereby closing the first door 81a, 81b as shown in FIG. The second doors 82a and 82b are opened. Thereby, the person U1 in the waiting room 80 can enter the adjacent special living room through the second entrance / exit in which the second doors 82a and 82b are opened. At this time, since the first doors 81a and 81b are closed, it is impossible to check the adjacent special living room through the waiting room 80 from the outside of the first doors 81a and 81b.

  After the control signals are output (S33, S35), the door control device resets the counter K (K = 0) and returns to the initial state (S21 in FIG. 5).

  On the other hand, for example, as shown in FIG. 10, when an authenticated person U1 enters the standby room 80 when an unauthenticated person Ux enters the standby room 80, the number of authenticated users K = 1. And the actual number of users N = 2 do not match (NO in S32), the door control device 50 assumes that there is a person who has not been authenticated as an authorized person among those who have entered the waiting room 80. A control signal for prohibiting the closing of one door is output and a control signal for prohibiting the opening of the second door is output (S35, S36). The door driving device 60 that receives these control signals maintains the first doors 81a and 81b in an open state and maintains the second doors 82a and 82b in a closed state. Then, for example, the door control device 50 determines whether or not a reset button provided on the wall in the standby chamber 80 has been operated (S38), and from a buzzer (not shown) installed in the standby chamber 80. A buzzer sound is generated (S37).

  The authorized person U1 can determine that the person Ux who has entered by the buzzer sound is a suspicious person. Moreover, the state which can confirm the mode in the waiting room 80 also from the outer side of the 1st doors 81a and 81b of the waiting room 80 is maintained. If the reset button is operated (YES in S38), the door control device 50 returns to the initial state (S21 shown in FIG. 5) after resetting the counter value K (S35). Then, when a predetermined operation is performed on the operation panel provided outside the standby chamber 80, the first doors 81a and 81b are returned to the initial state (closed state) as shown in FIG.

  According to the door control device 50 that controls the operation of the first doors 81a and 81b as described above, only the person who previously registered the ID information and possessed the IC card storing the ID information has the first door 81a, 81b can be opened. Further, when the first doors 81a and 81b are opened and the number of actual users N obtained when the user enters the waiting room 80 and the number of authenticated users K match, the first doors 81a and 81b The second doors 82a and 82b are opened while being closed. Thereby, when all the users who entered the waiting room 80 are regular users, the first doors 81a and 81b are closed and the second doors 82a and 82b are opened.

  On the other hand, if the number N of actual users and the number K of authenticated users do not match, the open state of the first doors 81a and 81b is maintained and the closed state of the second doors 82a and 82b is maintained. Thus, as shown in FIG. 10, when the suspicious person Uk enters the waiting room 80 together with the authorized person U1, the second doors 82a and 82b are not opened, and the first door 81a, 81b is not closed. Therefore, the suspicious person Uk cannot enter the special living room adjacent to the waiting room 80, and the authorized person U1 is not confined in the waiting room 80 together with the suspicious person Uk.

  The door control device 50 according to the second embodiment described above controls the operations of the two doors provided in the standby chamber 80, the first door 81a, 81b and the second door 82a, 82b. However, for example, two doors such as an entrance door and an elevator door provided in a space (elevator hall) following the elevator from the entrance of a building such as an apartment may be controlled. In this case, the entrance door corresponds to the first doors 81 a and 81 b described above, the elevator door corresponds to the second doors 82 a and 82 b described above, and the elevator hall corresponds to the waiting room 80.

  By the operation control as described above for the entrance door and the elevator door, only the person who previously registered the ID information and possessed the IC card storing the ID information can open the entrance door. When the entrance door is opened and the number of actual users N obtained when the user enters the elevator hall and the number of authenticated users K match, the entrance door is closed and the elevator door is opened. Become acceptable. Thereby, when all the users who entered the elevator hall are regular users, the entrance door is closed and the elevator door is allowed to open.

  On the other hand, when the entrance door is opened, if the suspicious person enters the elevator hall with the accompanying person, the number N of actual users and the number K of authorized users do not match, and the entrance door is kept open. In addition, the closed state of the elevator door is maintained. As a result, the authorized user can quickly exit the building from the entrance door, and further prevent the suspicious person from further using the elevator. Moreover, the state which can confirm the mode of an elevator hall from the outside of a building is maintained.

  In the process shown in FIG. 6, the first doors 81a and 81b are closed and the second doors 82a and 82b are opened only when the number of actual users N and the number of authenticated users K match. However, as in the process shown in FIG. 2, when the number of authenticated users K is greater than or equal to the actual number of users N, or when the actual number of users N is less than or equal to the number of authenticated users K, The first doors 81a and 81b can be closed, and the second doors 82a and 82b can be opened.

  As described above, the door control device and method according to the present invention allows a legitimate person and a suspicious person to enter the predetermined space when the suspicious person enters the predetermined space together with the legitimate person. This has the effect of appropriately controlling the operation of the door so as not to be trapped, and is useful as a door control device and method for controlling the opening and closing of the door provided at the entrance / exit of a space such as an elevator car.
