Description

  Embodiments described herein relate generally to an elevator apparatus.

  When a disaster such as a fire occurs in a building, it has been common to evacuate using emergency stairs. However, it is not easy for a wheelchair user, a person with difficulty walking, an elderly person and a child to evacuate using emergency stairs. Particularly in high-rise buildings, it is extremely difficult for vulnerable people to evacuate using emergency stairs. Therefore, a method of actively evacuating vulnerable people using an elevator has been proposed.

  However, conventionally, it has been difficult to accurately grasp the existence of vulnerable refugees, and it has been difficult to evacuate refugees using an elevator.

  Therefore, there is a demand for an elevator apparatus that can effectively evacuate vulnerable people using an elevator.

  The elevator apparatus according to the embodiment includes an image acquisition unit that acquires a landing image for each floor, a detection unit that detects a specific person having a predetermined characteristic from the image acquired for each floor by the image acquisition unit, and A control unit that registers the call of the floor where the specific person is detected by the detection unit and controls the floor to stop the car.

It is the figure which showed typically the structure of the elevator apparatus which concerns on embodiment. It is the flowchart which showed the operation | movement of embodiment. It is the flowchart which showed the operation | movement of embodiment.

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

  FIG. 1 is a diagram schematically illustrating a configuration of an elevator apparatus according to the embodiment.

  The elevator control unit 10 controls the entire elevator such as elevator operation control. In the elevator control unit 10, when a disaster such as a fire occurs, operation control of the elevator for disaster occurrence is performed by a method described later.

  Elevator doors 20 are provided on each floor of the building. When an elevator car (not shown) stops on each floor, the doors 20 are opened and users can get on and off.

  A call registration device 30 is provided in the vicinity of the door 20 on each floor, and when the call registration is performed by the call registration device 30, the elevator car stops at the floor where the call is registered during normal operation during a non-disaster.

  In addition, a monitoring camera 40 is installed in the vicinity of the door 20 on each floor to capture the state of the landing. This surveillance camera normally functions as a security camera, but is also used for detecting vulnerable persons such as wheelchair users, persons with difficulty walking, elderly people, and children when a disaster occurs. That is, it is used to detect specific persons having predetermined characteristics such as wheelchair users, persons with difficulty walking, elderly people, and children.

  The monitoring cameras 40 on each floor are connected to the input switching device 50 by a coaxial cable, and a video signal (NTSC signal) from the monitoring camera 40 is input to the input switching device 50. By this input switching device 50, the video signal of the monitoring camera 40 is sequentially switched, for example, from the lower floor to the upper floor every second, and is sent to the weak detection section 60 together with the corresponding floor information.

  The monitoring camera 40 and the input switching device 50 described above constitute an image acquisition unit that acquires a landing image for each floor.

  The weak person detection unit 60 detects a specific person having a predetermined characteristic from the images acquired for each floor by the image acquisition unit. That is, weak evacuation persons such as wheelchair users, persons with difficulty walking, elderly people, children, and the like are detected based on video signals sequentially sent to each floor. Specifically, the weak detection unit 60 includes a wheelchair detection unit 61, a cane detection unit 62, and an elderly / child detection unit 63, and the weak detection unit 60 detects a characteristic portion of an evacuated weak person.

  For the detection of vulnerable evacuation persons, the following known image processing methods can be used. First, the difference between the background image stored in advance and the image of the monitoring camera 40 is calculated, and an image from which the background has been deleted is generated using mask processing. Then, circles and straight lines are detected using the Hough technique. It is considered that a wheelchair has been detected by detecting a circle having a predetermined number of dots or more. A cane is detected to detect those who have difficulty walking. A known method can also be used for cane detection. The elderly / child detection is realized by, for example, the age group determination system of a tobacco vending machine.

  The detection signal of the weak detection unit 60 is sent to the elevator control unit 10. The elevator control unit 10 performs control so that when a disaster occurs, the call of the floor where the vulnerable evacuation person is detected is registered and the car is stopped on the floor. In addition, when a call of a floor where no evacuated vulnerable person is detected is registered, the call of the floor is canceled. That is, control is performed so that the elevator car is stopped only on the floor where the vulnerable evacuation person is detected, whether the call registration button is pressed or not.

  A speaker 70 is installed in the vicinity of the elevator platform as a notification unit, and evacuation guidance information is output from the speaker 70 when a disaster occurs. Specifically, a notification is made so that the vulnerable evacuation person moves to the platform. Thereby, the image of a weak evacuation person can be acquired reliably by the monitoring camera 40 installed in the landing, and the refugee weak person can be reliably detected. As a result, it is possible to quickly guide vulnerable people to the elevator. In addition, the non-evacuation vulnerable person is notified by the speaker 70 that he / she should evacuate from the stairs without using the elevator. Thereby, only an evacuation weak person can use an elevator.

  Next, the operation when a disaster occurs according to this embodiment will be described.

  FIG. 2 is a flowchart showing the operation of the present embodiment, and is a flowchart mainly showing an operation of detecting a weak evacuation by the weak detection unit 60.

  First, “kai1 = 0, kai2 = 0” is input as an initial value (S1). Here, “kai2” indicates the floor where the video signal of the monitoring camera 40 and the floor information are input. “Kai1” indicates the floor on which image processing for detecting a vulnerable refugee is performed based on the video signal.

  Next, the floor information kai2 and the corresponding video signal are input (S2). Initially, “kai2 = 1” is set, and the video signal of the monitoring camera 40 provided at the landing on the first floor is input to the weak detection unit 60 via the input switching device 50 together with the floor information (kai2 = 1).

  Next, it is determined whether or not “kai1 = kai2” (S3). If “kai1 = kai2”, the process returns to step S2. If it is not “kai1 = kai2”, “kai1 = kai2”, that is, the value of kai2 is substituted into kai1 (S4). In the first stage, since “kai2 = 1” and “kai1 = 0”, the process proceeds to step S4.

  It supplements about the step (loop) of S2 and S3 mentioned above. As described above, the video of the surveillance camera 40 is sequentially switched from the lower floor to the upper floor, for example, every second by the input switching device 50, and sent to the weak detection section 60 together with the corresponding floor information. Therefore, the floor information “kai2” in step S2 is sequentially updated every second, for example. When the floor information “kai2” is updated, the value of kai2 increases by 1. As a result, kai1 and kai2 have different values, and the process proceeds to step S4.

  In step S4, the value of kai2 is substituted for kai1 (S4). In the first stage, since “kai2 = 1” and “kai1 = 0”, “kai1 = kai2 = 1” is obtained in step S4.

  Next, initialization is performed with “Data [kai1] = 0” (S5). Here, “Data [kai1] = 0” indicates that there is no vulnerable person on the floor represented by kai1. If there are vulnerable refugees on the floor represented by kai1, “Data [kai1] = 1”.

  Next, it is determined whether or not a circle or ellipse of a certain size or more has been detected (S6). That is, it is determined whether or not there is a wheelchair user on the floor represented by kai1 (the first floor in the first stage). If a circle or ellipse with a certain size or more is detected, “Data [kai1] = 1” is set, and a setting is made that there is a vulnerable evacuation person on the floor represented by kai1 (S7).

  Next, it is determined whether or not a wand has been detected (S8). That is, it is determined whether or not there is a person who has difficulty walking on the floor represented by kai1 (the first floor in the first stage). If a cane is detected, “Data [kai1] = 1” is set, and a setting is made that there is a vulnerable evacuation person on the floor represented by kai1 (S9).

  Next, it is determined whether or not a child or an elderly person has been detected (S10). That is, it is determined whether or not there is a child or an elderly person on the floor represented by kai1 (the first floor in the first stage). If a child or an elderly person is detected, “Data [kai1] = 1” is set, and a setting is made that there is a vulnerable evacuation person on the floor represented by kai1 (S11).

  Thereafter, the value of Data [kai1] obtained as described above is output (S12), and the process returns to the step S2.

  As described above, the above-described steps are repeated from the lowest floor (first floor) to the highest floor. As a result, “Data [kai1] = 1” is set for the floor where the vulnerable refugee is present, and “Data [kai1] = 0” is set for the floor where the vulnerable refugee is not present.

  FIG. 3 is a flowchart showing the operation of the present embodiment, and is a flowchart mainly showing a call registration operation and the like by the elevator control unit 10.

  First, the value of Data [kai1] is input (S21). That is, Data [kai1] from the lowest floor (first floor) to the highest floor acquired in the flowchart of FIG. 2 is input.

  Next, “y = ymin” and “total = 0” are set as initial values. Here, “y” represents a floor and “ymin” represents the lowest floor (first floor). “Total” represents the total sum of Data [kai1] from the lowest floor to the highest floor. That is, it represents the total number of floors where vulnerable evacuation persons exist. For example, if there are vulnerable people only on the 4th, 6th and 9th floors, “total = 3”. If there is no vulnerable person on any floor from the lowest floor to the top floor, “total = 0”.

  Next, step (loop) processing represented by S23 to S26 is executed. That is, while increasing the value of y by 1 until the value of y reaches ymax, the step “total = total + Data [y]” of S24 is executed. Here, “ymax” represents the top floor. In this way, the sum of Data [y] (sum of Data [kai1]) from the bottom floor to the top floor is calculated by steps S23 to S26.

  Next, it is determined whether or not “total> 0” (S27). That is, it is determined whether or not there are vulnerable evacuation persons on at least one floor from the lowest floor to the top floor.

  When there are no evacuated persons at all (when “total = 0”), a predetermined announcement is made to the landing on each floor. That is, the evacuation guidance information is output from the speaker 70 (notification unit) in FIG. Specifically, a notification is made so that the vulnerable evacuation person moves to the platform. For example, an announcement such as “If you are disabled, the elderly, or children, please move to the elevator platform”. In addition, a notice is given to non-evacuation vulnerable persons that they should evacuate from the stairs without using the elevator. For example, an announcement such as “If there is no problem with walking, please evacuate from the emergency stairs without using the elevator” is made. After making the announcement, the process returns to step S21.

  If there are vulnerable evacuation persons (when “total> 0”), “y = ymin” is set (S29). That is, the floor “y” is set to the lowest floor “ymin”.

  Next, step (loop) processing represented by S29 to S36 is executed. That is, steps S31 to S34 are executed while increasing the value of y by 1 until the value of y reaches ymax (top floor). Specifically, it is as follows.

  First, it is determined whether or not “Data [y] = 1” (S31). That is, it is determined whether or not there are vulnerable refugees on the y floor (S31).

  If Data [y] = 1 (when there is a vulnerable person on the y floor), the y floor call is registered (S32). That is, when the y-th floor call is not registered, the y-th floor call is registered, and when the y-th floor call is already registered, the registered state is maintained.

  When Data [y] is not 1 (when there is no vulnerable person on the y floor), the call on the y floor is canceled (S33). That is, when the y-th floor call is registered, the y-th floor call is canceled, and when the y-th floor call is not registered, the unregistered state (cancelled state) is maintained. Further, a predetermined announcement is made at the landing on the y-th floor (S34). That is, the evacuation guidance information is output from the speaker 70 (notification unit) in FIG. Specifically, as described in step S28, the evacuation vulnerable person is notified to move to the landing, and the non-evacuation weak person should be evacuated from the stairs without using the elevator. Notification.

  By executing the above-described steps (loops) S29 to S36, regardless of whether the call registration button is pressed or not, the floor where the vulnerable person is evacuated (the floor where the vulnerable person is detected by the weak person detection unit 60). Calls are registered, and calls on floors where there are no evacuated vulnerable persons (floors where evacuated vulnerable persons are not detected by the weak detection part 60) are cancelled. After the process of steps S29 to S36 is completed, the process returns to step S21.

  As described above, according to the present embodiment, the image acquisition unit (the monitoring camera 40 and the input switching device 50) acquires the image of the landing for each floor, and has a predetermined characteristic from the image acquired for each floor. Detect evacuated vulnerable people. And the call of the floor where the evacuation weak person was detected by the detection part is registered, and the car is stopped on the floor. With such a configuration, it is possible to accurately grasp the existence of weak evacuation persons, and it is possible to effectively evacuate refuge persons using elevators. Moreover, it becomes possible to evacuate a vulnerable evacuation more effectively using an elevator by canceling a call of a floor where a vulnerable refugee is not detected.
