Description

Technical Field

[0001] This invention relates to the field of elevator control technology, and in particular to an elevator control method based on wheelchair monitoring. Background Technology

[0002] In existing wheelchair-accessible elevator control systems, cameras are installed above the car entrances and exits. The images captured by these cameras are analyzed by an image analysis device. This device determines whether a wheelchair user is present at a floor. Even after determining that a wheelchair user is present at a floor, the following problems still exist:

[0003] First, although the camera detects the wheelchair, other people will still get on and off the elevator. The wheelchair user and other people together not only waste time, but also cause overcrowding in the elevator car.

[0004] Secondly, the elevator call system inside the car is only designed with a traditional call panel, which makes it difficult for wheelchair users to call the elevator according to their own situation, making it relatively difficult to use.

[0005] To address the aforementioned issues, this application discloses an elevator control method based on wheelchair monitoring. Summary of the Invention

[0006] To overcome the shortcomings of the prior art, this invention discloses an elevator control method based on wheelchair monitoring.

[0007] To achieve the above objectives, the technical solution adopted by this invention is: an elevator control method based on wheelchair monitoring, comprising an elevator car, a VIP mode controller, a call button panel, a first camera, and several second cameras. The first camera and the call button panel are both located inside the elevator car, and the several second cameras are respectively located outside the elevator lobby on each floor. The VIP mode controller is connected to the elevator control system and controls the elevator operation based on the detection information from the first camera and the several second cameras. The control method specifically includes the following steps:

[0008] S10, Second cameras installed outside the elevator lobbies on each floor detect wheelchairs that intend to use the elevator in the elevator lobbies;

[0009] S20, the VIP mode controller automatically calls the elevator to this floor and triggers the VIP standby mode;

[0010] S30: After the in-car camera detects that the wheelchair has completely entered the elevator car, it checks whether the buttons on the call button panel have been triggered.

[0011] S40, the elevator call button panel is triggered, the elevator responds to the command, arrives at the designated floor and opens the door;

[0012] In the S50, once the first camera detects that the wheelchair has left the cabin, the VIP mode is canceled and normal operation resumes.

[0013] More preferably, the elevator car is equipped with a call action recognition device to recognize call actions and upload them to the VIP mode controller.

[0014] When the elevator call button panel is not triggered and the elevator call action recognition device recognizes the elevator call action, the VIP mode controller will control the elevator response.

[0015] More preferably, the elevator call action recognition device is a voice recognition device and / or a gesture recognition device.

[0016] More preferably, the elevator car is equipped with a broadcast system for notifying wheelchair users to trigger the call button panel or the call action recognition device. If the wheelchair user does not trigger either the call button panel or the call action recognition device after a set time has elapsed since entering the elevator car, the broadcast system will issue a broadcast notification.

[0017] Further preferably, it also includes several external display panels for receiving VIP mode controllers, with the external display panels respectively located outside the elevator lobby on each floor, at least to inform people outside the elevator lobby on each floor that there are wheelchair users inside the elevator car.

[0018] More preferably, the first camera is used to detect a set area outside the elevator lobby. If the first camera detects that the wheelchair is completely within the detection area, the VIP mode controller automatically calls the elevator to that floor; or, if the first camera detects that most of the wheelchair is within the detection area and the wheelchair's forward direction is pointing towards the elevator lobby, the VIP mode controller automatically calls the elevator to that floor.

[0019] More preferably, the direction in which the wheelchair moves forward when its forward wheels tilt 0-3° to the left or right is defined as the forward direction.

[0020] Further preferably, if the second cameras on multiple floors detect a wheelchair, the VIP mode controller will automatically call the elevator to the floor where the wheelchair was first detected.

[0021] The present invention achieves the following beneficial effects:

[0022] The elevator control method designed in this application can trigger the elevator to enter VIP standby mode. In this mode, only wheelchair users can ride the elevator alone. This not only saves time but also avoids overcrowding in the elevator car, making it highly practical.

[0023] Other features and advantages of the invention will be set forth in the following description and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention can be realized and obtained by means of the structures pointed out in the description and the drawings. Attached Figure Description

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0030] Example

[0031] To address the problems in existing elevator control systems 100 that cannot perform special control based on wheelchair detection, which easily leads to overcrowding in the elevator car 10 and wastes time going up and down the elevator, reference is made to... Figure 1 and Figure 2As shown, this application discloses an elevator control method based on wheelchair monitoring, including an elevator car 10, a VIP mode controller 20, a call button panel 30, a first camera 40, and several second cameras 50. The first camera 40 and the call button panel 30 are both located inside the elevator car 10, and the several second cameras 50 are respectively located outside the elevator lobby on each floor. The VIP mode controller 20 is connected to the elevator control system 100 and controls the elevator operation based on the detection information from the first camera 40 and the several second cameras 50. The control method specifically includes the following steps:

[0032] S10, the second camera 50 installed outside the elevator lobby on each floor detects a wheelchair in the elevator lobby that intends to take the elevator; if the second camera 50 on multiple floors detects a wheelchair, the VIP mode controller 20 will automatically call the elevator to the floor where the wheelchair was first detected.

[0033] S20, VIP mode controller 20 automatically calls the elevator to this floor and triggers VIP standby mode;

[0034] S30, after the in-car camera detects that the wheelchair has completely entered the elevator car 10, it checks whether the buttons on the call button panel 30 have been triggered; in addition to the call button panel 30, the elevator car 10 is equipped with a call action recognition device 60 to recognize the call action and upload it to the VIP mode controller 20.

[0035] When the elevator call button panel 30 is not triggered and the elevator call action recognition device 60 recognizes the elevator call action, the VIP mode controller 20 will control the elevator to respond. The elevator car 10 is equipped with a broadcast device 70 to notify wheelchair users to trigger the elevator call button panel 30 or the elevator call action recognition device 60. After the wheelchair enters the elevator car 10 for a set time, if the wheelchair user does not trigger either the elevator call button panel 30 or the elevator call action recognition device 60, the broadcast device 70 will issue a broadcast notification.

[0036] S40, the elevator call button panel 30 is triggered, the elevator responds to the command, arrives at the designated floor and opens the door;

[0037] In the S50, once the first camera 40 detects that the wheelchair has left the cabin, the VIP mode is canceled and normal operation resumes.

[0038] Preferably, the elevator call action recognition device 60 of this application is a voice recognition device and / or a gesture recognition device. In specific implementation, this application can set up a voice recognition device and a gesture recognition device separately in the elevator car 10, or set up both a voice recognition device and a gesture recognition device in the elevator car 10. Based on the voice recognition device and the gesture recognition device, when a person in a wheelchair cannot reach the elevator call button panel 30, he / she can call the elevator by directly saying the floor he / she wants to go to or by giving the floor he / she wants to go to through gesture.

[0039] In addition, this application also includes several external display panels 80 for receiving VIP mode controller 20. The external display panels 80 are respectively set at the outside of the elevator hall on each floor, at least to inform people outside the elevator hall on each floor that there are wheelchair users in the elevator car 10. That is to say, before the wheelchair reaches the set floor, people outside the elevator hall can make way in advance so that the wheelchair can get out of the car and then enter the elevator. In this way, the congestion outside the elevator hall can be reduced, the elevator travel time can be reduced, and it has strong practicality.

[0040] In order to accurately identify wheelchairs outside the elevator lobby, the first camera 40 of this application is used to detect a set area outside the elevator lobby. If the first camera 40 detects that the wheelchair is completely located in the detection area 90, the VIP mode controller 20 automatically calls the elevator to that floor; or, if the first camera 40 detects that most of the wheelchair is located in the detection area 90 and the wheelchair's forward direction is pointing towards the elevator lobby, the VIP mode controller 20 automatically calls the elevator to that floor. Except for the above two situations, the VIP mode controller 20 will not perform elevator call operation in other situations, such as when a small part of the wheelchair is located in the area, or when the wheelchair's forward direction is about to leave the elevator lobby.

[0041] Specifically, it should be noted that when the wheelchair's forward wheels tilt 0-3° to the left or right, the direction of forward movement is defined as the forward direction. If the angle of the wheelchair's forward wheels tilting to the left or right is greater than 3°, then it cannot be concluded that the person in the wheelchair intends to take the elevator.
