FIG. 3 is an operation flowchart showing an example of operations related to transmission of a camera video signal based on a command from the system remote management device following FIG. 2 and editing of face image data stored in the face image storage device.

  Hereinafter, the operation of the elevator security system will be described with reference to FIG. The video input / output I / F 6 outputs the video signal output from the camera 1 to the monitor 2 and also to the system control device 7. The system control device 7 extracts a person's face image based on the video signal photographed by the camera 1, but when a person's image of an elevator user can be photographed but cannot be extracted (steps S1 and S2), An announcement command is output so as to issue a guidance announcement to the announcement command control device 9, and the elevator user is guided to move to a position where a face image can be extracted from the camera video (step S3).

  When the face image has been extracted (step S4), a command to output an announcement of completion of face image shooting is output to the announcement command control device 9, and the fact that the face image has been shot to the elevator user is confirmed. Inform (step S5).

  Then, the captured face image data is stored in the all-user face image storage area 8c of the face image storage device 8 (step S6). Further, it is identified whether or not the face image data matches the face image data stored in the specific user face image storage area 8a and the prohibited user face image storage area 8b of the face image storage device 8. When it matches the face image data in the specific user face image storage area 8a (step S7), the user's destination floor information (for example, expressed as 00h to FFh) stored as use information accompanying the face image data. If it is 08h, the destination floor is the eighth floor), and the destination floor information is output to the call registration control device 10 as a control signal.

  Here, the call registration control device 10 that controls transmission of information related to call registration from the call registration device 4 will be described. The call registration control device 10 is a device that operates based on a control signal output from the system control device 7. Yes, when there is no control signal, it operates as an I / F of a button related information signal (button contact information, button lamp control information) that is information relating to mere call registration between the call registration device 4 and the elevator control panel 5 Does nothing and the elevator operates normally.

  When a control signal serving as destination floor information of a specific user based on identification of a face image is output from the system control device 7, elevator destination floor registration information is output to the elevator control panel 5 based on the control signal. At this time, the button control information corresponding to the destination floor information is output from the elevator control panel 5 to the call registration device 4 which is a hall call button or a car operation panel button. This is a normal I / F. Operates and does nothing, turns on the button light. Thereby, the button lamp control of the hall call button or the car operation panel button functions as usual, and the elevator destination floor is automatically registered.

  When the system controller 7 outputs a control signal that identifies the prohibited person's face image and disables the call button, the communication between the call registration device 4 and the elevator control panel 5 is cut off, and the elevator car call is registered. Prevent the elevator from functioning.

  Therefore, when the face image data in the specific user face image storage area 8a is matched in step S7 of FIG. 2, the specific user landing information and the destination floor from the system control device 7 based on the stored information of the face image storage device 8 are displayed. Based on the information, hall call registration and destination floor call registration are performed on the elevator control panel 5 (step S8). In addition, both the hall information and the destination floor information may be included as usage information, and the hall call registration and the destination floor call registration may be performed based on the user information, but either one is included as usage information and the other is a call registration device. 4 may be obtained from the button contact information from 4, and each call registration may be performed.

  On the other hand, if it matches the face image data in the prohibited person face image storage area 8b (step S9), a control signal for invalidating the button contact information from the call registration device 4 is output to the call registration control device 10 (step S9). S10) Outputs a command to issue a warning announcement to the announcement command control device 9 based on the video signal from the camera 1 until there is no prohibited user, so that the prohibited user is moved away from the elevator. (Step S11).

  If it does not match the face image data in any storage area of the specific user face image storage area 8a and the prohibited user face image storage area 8b, it is identified as a general visitor, and a control signal is sent to the call registration control device 10. Without output, the elevator operates normally based on the button contact information from the call registration device 4 (No in step S9).

  Here, in the face image storage device 8, the face image data is stored or read out by the system control device 7 as described above. Therefore, for the face image data in the specific user face image storage area 8a and the prohibited user face image storage area 8b, the face image data stored with the newly extracted face image data is updated, and all the user face images are updated. The storage area 8c can be provided with a function of erasing stored data after a preset storage period (period length can be freely set) elapses. Therefore, the face image data stored in the all-user face image storage area 8c is added with date / time information when stored.

(a) is an image deletion process for the entire user face image storage area 8c, and is executed constantly or at a predetermined cycle, and (b) is a specific user face image storage area 8a and a prohibited user face image storage area 8b. The image update process is shown in FIG. 2 and is executed in parallel with steps S6 to S9 in FIG.

  In FIG. 4A, there is face image data that has passed a predetermined storage period based on the date and time information of the face image data in the all-user face image storage area 8c and the date and time of the timer function built in the system control device 7. Whether or not the face image data that has passed the predetermined storage period is deleted (step S2).

  In FIG. 4B, when face image data is stored (stored) in the all-user face image storage area 8c (step S1), if this is for a specific user or a prohibited user (step S1). S2) The corresponding stored face image data in the specific user face image storage area 8a or the prohibited user face image storage area 8b is updated (replaced) with the new face image data. At this time, only the face image data is updated, and the usage information associated with the face image data of the specific user is kept as it is (step S3). This is performed for all newly stored face image data (step S4).

  In addition, the announcement command control device 9 receives the announcement command output from the system control device 7 as described above, and also receives the normal announcement command output from the elevator control panel 5. The announcement command output from the elevator control panel 5 is generally a command for announcing important messages such as for preventing danger to the elevator user, so that the command is given priority to the announcement device 3. Output to.

  The announcement command input from the system control device 7 is output to the announcement device 3 only when there is no announcement command from the elevator control panel 5, and guides the user to take a face image or warns the prohibited user. Announce an announcement to make However, when an announcement command is input from the elevator control panel 5 during the announcement notification or the like, the announcement notification is immediately switched to the announcement notification based on the announcement command input from the elevator control panel 5 by interruption processing or the like.

  Thus, the announcement of the security system is issued to the elevator user without obstructing the announcement based on the command from the elevator control panel 5.

  The system remote management device 11 includes an operation unit such as a personal computer, a display unit, a storage unit, a control processing unit, a communication unit, and the like (both not shown). It is installed in the place. The system remote management device 11 and the system control device 7 are connected by a serial communication line such as a LAN, for example, and perform serial bidirectional communication. When it is installed outside a building with an elevator such as a maintenance company, it is further connected via ADSL or optical cable transmission. Note that the call registration device 4 including the hall call button or the car operation panel button and the call registration control device 10 are also connected by a serial communication line to perform serial bidirectional communication.

  The operation related to the transmission of the camera video signal based on the command from the system remote management device and the editing of the face image data stored in the face image storage device will be described according to the operation flowchart of FIG. 3 following FIG. When a video request command is output from the system remote management device 11 according to the operation of the operation unit by the operator (step S13), the system control device 7 receives the video signal captured by the camera 1 through the video input / output I / F 6. Digitally modulated and transmitted to the system remote management apparatus 11 in real time (step S14). Thus, the system remote management apparatus 11 can display and monitor the video on the display unit by operating the operation unit.

  When a face image request command is output from the system remote management device 11 according to the operation by the operator (step S15), the system control device 7 stores all the face image data in the storage areas 8a to 8c of the face image storage device 8 in the system. It transmits to the remote management apparatus 11 (step S16). Note that a storage area in the face image storage device 8 that requests a face image may be specified by a face image request command. In this case, all face image data in the specified area is transmitted to the system remote management apparatus 11.

  The face image can be displayed on the display unit according to the operation of the operation unit by the system remote management device 11. The face image data is temporarily stored in the storage unit of the system remote management device 11 and displayed on the display unit while selecting the face images one by one according to the operation of the operation unit, or collectively displayed on the display unit. be able to.

  In the system remote management device 11, the face image data in the specific user face image storage area 8 a and the prohibited person face image storage area 8 b of the face image storage device 8 is updated with the face image sent from the system control device 7. , Register facial image data, or cancel registration.

  For example, when updating face image data of a specific user or prohibited user, classification information indicating the classification of the face image data according to the operation of the operation unit by the operator from the system remote management device 11 (use information in the case of a specific user) The destination image information can be used as classification information), and face image update data, which is face image edit data added with edit type information (update, registration, deregistration, etc.) indicating the processing type, is output (step S17). In response to this, the system control device 7 confirms the classification type and editing type from the classification information and editing type information of the face image update data, and selects face image update data (step S18).

  For example, if the sent face image update data is for updating data to a specific user (step S19), the face image data in the specific user face image storage area 8a has been sent. Update with face image data and save. The old data is deleted (step S20). If the sent face image update data is for updating data to the prohibited user (step S21), the received face image data in the prohibited user face image storage area 8b is sent. Update and save with image data. The old data is deleted (step S22). This is repeated until there is no face image update data (step S23).

  In particular, in the case of data update or deregistration, in order to easily search the face image data in the specific user face image storage area 8a and the prohibited user face image storage area 8b, for example, each face image data is serialized. An identification symbol such as a number may be added.

  Also, when the face image editing data is face image registration data or face image registration cancellation data, face image registration and face image registration cancellation are performed in the same manner. In the case of deregistration, there is no need for face image data if there is an identification symbol.

  Further, when the same registered person is updated to a new face image, only the face image data may be updated, and the information associated therewith may be left as it is.

  FIG. 5 shows the system remote management apparatus 11 when the face image data is registered from the system remote management apparatus 11 to the specific user face image storage area 8a and the prohibited person face image storage area 8b of the face image storage apparatus 8. The operation | movement flowchart which shows operation | movement is shown, and operation | movement is demonstrated according to this. However, the operation flowchart of FIG. 5 includes an operator's judgment.

  When the operator of the system remote management device 11 tries to monitor the image captured by the camera 1 on the display unit (step S1) and performs a predetermined operation on the operation unit, a video request command is output to the system control device 7 (step S2). When a video signal is sent from the system controller 7 in response to this, it is input and displayed on the display unit (step S3).

  After the video is monitored on the display unit, when there is a user who should register face image data as a specific user or a prohibited user in the face image storage device 8 (step S4), the face image taken and extracted by the camera 1 is extracted. When used (step S5), when a predetermined operation is performed on the operation unit, a face image request command is output to the system control device 7 (step S6), and in response thereto, the system control device 7 outputs a face image storage device. Since all the face image data in all the user face image storage areas 8c of 8 are sent, they are input and displayed on the display unit, or temporarily stored in the storage unit and sequentially displayed (step S7). . If the face image stored in the medium or the system remote management device 11 is connected to the network, the face image distributed on the network is input and displayed on the display unit (step S8).

  When registering a specific user (step S9), classification information indicating the classification of face image data to be registered (in the case of a specific user, for example, destination floor information which is usage information), edit type information indicating a processing type ( In this case, registration), and face image registration data, which is face image editing data to which an identification symbol or the like is added, is output to the system control device 7 for registration and instruction (step S10).

  Further, when registering a prohibited user (step S11), classification information indicating a classification in the facial image data to be registered (indicating a prohibited user), editing type information indicating a processing type (in this case, registration), and identification The face image registration data, which is face image editing data to which symbols and the like are added, is output to the system control device 7 for registration and instruction (step S12).

  As a result, the system control device 7 performs registration processing according to the face image registration data.

  As described above, according to the present invention, a security system that identifies and identifies a person from a registered and stored face image, controls call registration according to the classification of the person, and achieves both passenger convenience improvement and crime prevention effect. Can provide.

  Also, based on the information given to the users, it is classified and identified as authorized users, prohibited users, and other users. By performing automatic registration control corresponding to the elevator user's usage information, it is possible to provide a security system with a high crime prevention effect while further improving passenger convenience.

  In addition, the extracted face image is selected by remote operation, and the face image of a specific user or prohibited user who should be newly registered, updated, or unregistered is saved or deleted in the face image storage device to make the user aware of it. It is possible to provide a highly responsive security system that can immediately update or delete a face image without improving the convenience of passengers and security accuracy.

  Also, if the face image is identified as a prohibited user from the video taken by the camera, a warning announcement will be issued without obstructing the elevator announcement that is issued based on the announcement command from the elevator control panel. As a result, the crime prevention effect is further improved.

  In addition, it is more convenient for a specific user by automatically registering a hall call or a destination floor call in a car based on elevator use information.

  Also, all the extracted face images are stored in the face image storage device, face images classified as specific users and prohibited users are replaced with stored face images, and other face image data is stored for a predetermined period. By erasing it after elapses, the extracted face image data can be used like ordinary security camera data, and the stored face image is updated to a new face image, so that the storage capacity can be saved.
