To simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present application. In addition, the present application may repeat reference numerals and / or reference letters in different examples.

[0021] The embodiments of the present application are described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present application and should not be construed as a limitation of the present application.

[0022] Please refer to Figure 1 , the present application provides an elevator control method based on a car detection area. The elevator control method includes: 01: Obtain a feedback signal that an object is placed in the elevator car, where the feedback signal is associated with a detection area in the car, and different detection areas correspond to the same or different feedback signals, and the feedback signal includes a door closing signal and / or a normally open door signal; 02: Control the operation of the elevator based on the feedback signal.

[0023] Please refer to Figure 2 , the present application also provides an elevator control device 10 based on a car detection area. The elevator control device 10 includes a control module 11.

[0024] Step 01 and step 02 can be implemented by the control module 11. The control module 11 is used to obtain a feedback signal that an object is placed in the elevator car, where the feedback signal is associated with a detection area in the car, and different detection areas correspond to the same or different feedback signals, and the feedback signal includes a door closing signal and / or a normally open door signal; control the operation of the elevator based on the feedback signal.

[0025] Specifically, the feedback signal includes a door closing signal and / or a normally open door signal, and specifically includes the following three cases: (1) the feedback signal includes a door closing signal; (2) the feedback signal includes a normally open door signal; (3) the feedback signal includes a door closing signal and a normally open door signal. In this application, the elevator door can be controlled to close only based on the door closing signal, or the elevator can be controlled to keep the door open only based on the normally open door signal, or the elevator door can be controlled to close or keep the door open based on both the door closing signal and the normally open door signal.

[0026] Different detection areas correspond to the same or different feedback signals, which means that different detection areas can correspond to the same feedback signal or different feedback signals. For example, the detection areas in the car include three areas A, B, and C. Areas A and B can correspond to the same feedback signal, and the feedback signals corresponding to areas A and B can both be normally open door signals. Area C corresponds to a feedback signal different from that of areas A and B, and the feedback signal corresponding to area C can be a door closing signal.

[0027] That is to say, the elevator control method of this application can divide the elevator car into areas, and detect whether there is an object in the detection areas inside the elevator car through a detection instrument. The object can be an object such as goods or a robot, and there is no limitation here. When the detection instrument detects that an object is placed in a certain detection area inside the elevator car, a feedback signal corresponding to the detection area can be sent out, so as to control the elevator to close or keep the door open.

[0028] In this way, when an object is placed in the detection area inside the elevator, the elevator control method of this application can send out a feedback signal corresponding to the detection area, and automatically control the elevator to close or keep the door open based on this feedback signal, realizing the automatic control of the elevator to keep the door open or close without manual triggering of the elevator closing or opening action, and without detecting whether the objects inside the elevator car are fully loaded, which is simple and fast.

[0029] Please refer to Figure 3 , this application provides an elevator control method. The elevator control method includes: 011: When it is detected that an object is placed in the first detection area inside the elevator car, send out a door closing signal; wherein, there is one or more detection areas inside the elevator car, and the detection areas are used to detect the placement state of the object to control the elevator to close or keep the door open; 021: Control the elevator to close the door according to the door closing signal.

[0030] Please combine with Figure 2, Step 011 and Step 021 can be implemented by the control module 11. The control module 11 is used to send a door closing signal when it detects that an object is placed in the first detection area inside the elevator car; wherein, one or more detection areas are provided inside the elevator car, and the detection areas are used to detect the placement state of the object to control the elevator to close the door or keep the door open; and is used to control the elevator to close the door according to the door closing signal.

[0031] Specifically, the placement state of the object in the detection area includes a first state where an object is placed and a second state where no object is placed.

[0032] One detection area can be provided inside the elevator car, and this detection area is used to detect the placement state of the object to control the elevator to close the door or keep the door open. When one detection area is set inside the elevator car, this detection area can be a part of the elevator car area. The setting position of this detection area can be set by default or set according to user needs, and no limitation is made here.

[0033] Multiple detection areas can also be provided inside the elevator car. The multiple detection areas are used to detect the placement state of the object to control the elevator to close the door or keep the door open, which means that by detecting whether an object is placed in different areas inside the elevator car, the elevator door is controlled to open or close. That is, different areas inside the elevator car can be divided into different functional areas for controlling the elevator door to open or close.

[0034] The multiple detection areas can be 2 detection areas, 3 detection areas or 4 detection areas, and no limitation is made here.

[0035] As Figure 4 shown, the area inside the elevator car is divided into 2 detection areas, and the 2 detection areas are Area A and Area B respectively. The function of Area A can be set to control the elevator to keep the door open when it detects that an object is placed in Area A, that is, control the elevator to maintain the open door state. The function of Area B can be set to control the elevator to close the door when it detects that an object is placed in Area B.

[0036] As Figure 5 shown, the area inside the elevator car is divided into 3 detection areas, and the 3 detection areas are Area A, Area B and Area C respectively. The function of Area A can be set to control the elevator to keep the door open when it detects that an object is placed in Area A, that is, control the elevator to maintain the open door state. The function of Area B can be set to control the elevator to keep the door open when it detects that an object is placed in Area B, that is, control the elevator to maintain the open door state. The function of Area C can be set to control the elevator to close the door when it detects that an object is placed in Area C.

[0037] As Figure 6As shown in the figure, the area inside the elevator car is divided into 4 detection areas, namely Area A, Area B, Area C, and Area D. The function of Area A can be set to control the elevator to keep the door open when a target object is detected in Area A, that is, to control the elevator to remain open. The function of Area B can be set to control the elevator to keep the door open when a target object is detected in Area B, that is, to control the elevator to remain open. The function of Area C can be set to control the door of the elevator to keep the door open when a target object is detected in Area C, that is, to control the elevator to remain open. The function of Area D can be set to control the elevator to close the door when a target object is detected in Area D.

[0038] The first detection area is a functional area inside the elevator car that can control the door of the elevator to close. For example, the first detection area can be Area B in Figure 4 , Area C in Figure 5 and Area D in Figure 6 . The door closing signal can be a current or voltage signal, which is not limited here.

[0039] In addition, the first detection area can be set within a preset area range near the door of the elevator inside the elevator car, or the first detection area can also be set within a preset area range near the side wall of the elevator inside the elevator car.

[0040] In this way, when a target object is placed in the first detection area inside the elevator, the elevator control method of the present application can automatically control the elevator to close the door, realizing that there is no need for manual triggering of the elevator closing or opening action, nor is it necessary to detect whether the objects inside the elevator car are fully loaded, and the elevator can be automatically controlled to close the door, which is simple and fast.

[0041] Please refer to Figure 7 , in some embodiments, the elevator control method includes: 012: When a target object is detected in the second detection area inside the elevator car, a signal to keep the door open is issued; where there is one or more detection areas inside the elevator car, and the detection areas are used to detect the placement state of the target object to control the elevator to close the door or keep the door open; 022: Control the elevator to keep the door open according to the signal to keep the door open.

[0042] Please refer to Figure 2 , steps 012 and 022 can be implemented by the control module 11. That is to say, the control module 11 is used to issue a signal to keep the door open when a target object is detected in the second detection area inside the elevator car; where there is one or more detection areas inside the elevator car, and the detection areas are used to detect the placement state of the target object to control the elevator to close the door or keep the door open; and is used to control the elevator to keep the door open according to the signal to keep the door open.

[0043] Specifically, the second detection area is the functional area in the elevator car that can control the normally open function of the elevator door. For example, the second detection area can be the Figure 4 Area A in Figure 5 Area A and Area B in Figure 6 Area A, Area B, and Area C in . The door closing signal can be an electrical signal.

[0044] In this way, when there is an object in the second detection area inside the elevator, the elevator control method of the present application can automatically control the elevator to keep the door open, realizing that there is no need for manual operation to continuously trigger the action of keeping the elevator door open, nor is it necessary to detect whether the objects in the elevator car are fully loaded, and the elevator can be automatically controlled to maintain the door open state, which is simple and fast.

[0045] In some embodiments, the first detection area is one or more, and / or the second detection area is one or more. That is, the division of the first detection area and the second detection area can include the following situations: (1) the first detection area is one, and the second detection area is one; (2) the first detection area is one, and the second detection area is multiple; (3) the first detection area is multiple, and the second detection area is one; (4) the first detection area is multiple, and the second detection area is multiple.

[0046] Specifically, the number of the first detection areas can be 1, 2, or 3, which is not limited herein. When the number of the first detection areas is 1, for example, the first detection area can be the Figure 4 Area B in Figure 5 Area C in Figure 6 and Area D in . Similarly, the number of the second detection areas can be 1, 2, or 3, which is not limited herein.

[0047] It should be noted that there can also be other placement areas in the elevator car of the elevator of the present application that are not set with function detection, or there can be only the first detection area and the second detection area.

[0048] The division method of the first detection area and the second detection area divided in the elevator car in the elevator control method of the present application is more flexible and can be applied to different application scenarios.

[0049] It can be understood that when there are multiple first detection areas, it can be set that as long as an object is detected in any one of the first detection areas, the elevator is controlled to close the door. In addition, if objects are detected in multiple first detection areas at the same time, the elevator can also be controlled to close the door. If objects are detected in multiple first detection areas successively, the elevator can be controlled to close the door after the object is placed in the last first detection area is completed.

[0050] Please refer to Figure 8, in some embodiments, there is one first detection area and one or more second detection areas. The elevator control method further includes: 023: When the target object needs to be placed in the elevator car in multiple times, when it is detected that the target object is first placed in the second detection area, control the elevator to keep the door open based on the door-open signal; 024: After it is continuously detected that the remaining target objects are placed in the first detection area, control the elevator to close the door based on the door-close signal.

[0051] Please combine Figure 2 , steps 023 and 024 can be implemented by the control module 11. That is, the control module 11 is used to control the elevator to keep the door open based on the door-open signal when it is detected that the target object is first placed in the second detection area when the target object needs to be placed in the elevator car in multiple times; after it is continuously detected that the remaining target objects are placed in the first detection area, control the elevator to close the door based on the door-close signal.

[0052] Specifically, in the car area of the elevator, there is both a first detection area and a second detection area, and there is one first detection area and one or more second detection areas.

[0053] At this time, when the target object needs to be placed in the elevator car in multiple times, when it is detected that the target object is first placed in one or more second detection areas, the door-open signal corresponding to the second detection area can be sent out, and then the elevator is controlled to keep the door open according to the door-open signal. After it is detected that the remaining target objects are placed in the first detection area, the door-close signal corresponding to the first detection area can be sent out, and then the elevator is controlled to close the door according to the door-close signal.

[0054] In this way, the elevator control method of the present application can be provided with one or more second detection areas and one first detection area in the elevator car at the same time, so that when the number of target objects is large and needs to be placed in the elevator car in multiple times, the target objects can be first placed in the second detection area, the elevator can be automatically controlled to keep the door open, and then the remaining target objects can be placed in the first detection area, so as to automatically control the elevator to close the door.

[0055] In some embodiments, the elevator control method includes: 03: When it is detected that a target object is placed in any one of the multiple second detection areas, send out an open-door signal and control the elevator to keep the door open according to the door-open signal; or 04: When it is detected that target objects are placed in the multiple second detection areas at the same time, send out multiple door-open signals at the same time and control the elevator to keep the door open according to the multiple door-open signals; or 05: When it is detected that a target object is placed in the first detection area successively, send out a door-close signal and control the elevator to close the door according to the last sent door-close signal.

[0056] Please combine Figure 2 , step 03, step 04 and step 05 can be implemented by the control module 11. The control module 11 is used to send a door opening signal when it is detected that a target object is placed in any of the multiple second detection areas, and control the elevator to open the door according to the normally open door signal; or when it is detected that multiple second detection areas are simultaneously placed with target objects, send multiple normally open door signals at the same time, and control the elevator to open the door according to the multiple normally open door signals; or when it is detected that the first detection area is successively placed with target objects, send a door closing signal, and control the elevator to close the door according to the last door closing signal sent.

[0057] Specifically, when a target is detected in any of the plurality of second detection areas, a normally open door signal is issued, and the elevator normally open door is controlled according to the normally open door signal. As long as a target is detected in any of the second detection areas in the plurality of first detection areas, the elevator normally open door can be controlled.

[0058] When it is detected that multiple second detection areas are simultaneously placed with target objects, multiple normally open door signals are simultaneously issued, and the elevator normally open door is controlled according to the multiple normally open door signals. For example, when the target object is large in size and the second detection area is small in area, and the target object is simultaneously placed in two second detection areas, the two second detection areas can be triggered to issue normally open door signals at the same time, and at this time, the elevator normally open door can be controlled according to the two normally open door signals issued by the two second detection areas.

[0059] When it is detected that the target objects are placed successively in the only first detection area in the elevator car, a door closing signal is issued, and the elevator door is controlled to close according to the door closing signal. That is, as long as the target objects are placed in the first detection area, the elevator door can be immediately controlled to close.

[0060] In detail, in some embodiments, the time interval between the door closing signal and the elevator door closing can be set as a preset time, for example, the preset time is 1S, 2S or 3S, that is, after receiving the door closing signal, the elevator can be controlled to wait for the preset time before closing the door to prevent people from being injured by the elevator door.

[0061] In this way, the division method of the second detection area in the elevator car and the control method of closing the elevator door in the elevator control method of the present application are more flexible and can be applied to different application scenarios of transporting targets of different sizes or types.

[0062] In some embodiments, when there are multiple first detection areas in the elevator car, when it is detected that objects are successively placed in the multiple first detection areas, multiple door closing signals are successively sent out, and the elevator door closing is controlled according to the last sent door closing signal. For example, when the number of objects is large and the second detection area is full at this time, and the objects are successively placed in two first detection areas, then the two first detection areas will successively trigger and send out two door closing signals. At this time, it can be controlled to close the elevator door according to the second door closing signal triggered by the first detection area where the object is finally placed, and the door body of the elevator is controlled not to respond to the first door closing signal first for door closing.

[0063] Specifically, for example, the time interval between the door closing signal and the start of elevator door closing can be set to 2S. If no new door closing signal is received within 2S, the elevator is directly controlled to close the door. If a new door closing signal is received within 2S, the elevator is controlled to close the door after waiting for another 2S, and so on. Thus, it can be realized that when multiple door closing signals are successively sent out, the elevator door closing is controlled according to the last sent door closing signal.

[0064] In this way, the division method of the first detection area divided in the elevator car and the control method of controlling the elevator door closing in the elevator control method of the present application are more flexible and can be applied to different application scenarios for transporting objects of different sizes or different types.

[0065] It should be noted that when the elevator control method of the present application has multiple second detection areas, it can be set that as long as it is detected that an object is placed in one second detection area and no object is placed in the first detection area, the elevator is controlled to keep the door open.

[0066] In some embodiments, the elevator control method includes: 06: Controlling the elevator to send out a door closing prompt according to the door closing signal.

[0067] Please refer to Figure 2 , step 06 can be implemented by the control module 11. That is, the control module 11 is also used to control the elevator to send out a door closing prompt according to the door closing signal.

[0068] Specifically, for example, controlling the elevator to send out a door closing prompt according to the door closing signal can be to control the in-car call and / or the out-of-car call in the elevator to send out a door closing prompt according to the door closing signal.

[0069] Controlling the in-car call and / or the out-of-car call in the elevator to send out a door closing prompt according to the door closing signal includes the following situations: (1) Controlling only the in-car call in the elevator to send out a door closing prompt according to the door closing signal; (2) Controlling only the out-of-car call in the elevator to send out a door closing prompt according to the door closing signal; (3) Controlling both the in-car call and the out-of-car call in the elevator to send out a door closing prompt according to the door closing signal.

[0070] Understandably, when it is detected that an object is placed in the first detection area, the elevator car call or the elevator hall call is controlled according to the door closing signal to issue a door closing prompt, which can prompt the user that the elevator door is about to close at this time, thus avoiding the occurrence of an elevator clamping event for the user.

[0071] The door closing prompt can be, for example, a voice prompt, a text prompt, or a light flashing prompt, and is not limited herein. The voice prompt can be, for example, a voice broadcast of "The elevator door is about to close, please pay attention", and is not limited herein.

[0072] In this way, when the elevator control method of the present application controls the elevator to close the door according to the door closing signal, a door closing prompt can be issued to remind the user to pay attention that the elevator is about to close the door, avoiding the occurrence of an elevator clamping event.

[0073] In addition, similarly, the elevator control method of the present application can also control the elevator car call and / or the elevator hall call to issue a door always open prompt according to the door always open signal, thereby prompting the user that the elevator is in the door always open state at this time, facilitating the user to know the opening and closing state of the current elevator door. Among them, the door always open prompt can be, for example, a voice prompt, a text prompt, or a light flashing prompt, and is not limited herein. The voice prompt can be, for example, a voice broadcast of "The elevator door is in the door always open state, please pay attention", and is not limited herein.

[0074] In some embodiments, at least one sensor is provided in each detection area and / or a camera is provided in the car, and the elevator control method includes: 071: When it is detected by the sensor that an object is placed in the detection area, the feedback signal is issued; or, 072: When it is detected by the camera that an object is placed in the detection area, the feedback signal is issued; or, 073: When it is detected by the sensor and the camera simultaneously that an object is placed in the detection area, the feedback signal is issued.

[0075] Please combine Figure 2 , steps 071, 072, and 073 can be implemented by the control module 11. That is, the control module 11 is also used to issue the feedback signal when it is detected by the sensor that an object is placed in the detection area; or, to issue the feedback signal when it is detected by the camera that an object is placed in the detection area; or, to issue the feedback signal when it is detected by the sensor and the camera simultaneously that an object is placed in the detection area.

[0076] Specifically, the sensor can be, for example, an infrared sensor or other types of sensors, and is not limited herein. As Figure 4 , Figure 5 or Figure 6As shown, the sensor can be set at the bottom or the top of the car corresponding to the first detection area, and there is no limitation here. The number of sensors can be determined according to the number of the first detection areas. For example, if the number of the first detection areas is 2, the number of sensors corresponding to 1 first detection area can be 4, and the number of sensors corresponding to 2 first detection areas is 8, as Figure 5 shown.

[0077] The camera can be set at the top of the elevator car or above the side wall of the elevator car, as long as it can capture whether the target object is placed in the first detection area, and there is no limitation here. The number of cameras can be 1 or more, and there is no limitation here.

[0078] In one embodiment, only a sensor or a camera can be installed in the elevator car to detect whether a target object is placed in the first detection area, and when the sensor detects that a target object is placed in the first detection area, control the sensor to send a door closing signal, and when the camera detects that a target object is placed in the first detection area, control the camera to send a door closing signal.

[0079] In another embodiment, both a sensor and a camera can be installed in the elevator car to detect whether a target object is placed in the first detection area, and when the sensor and the camera detect that a target object is placed in the first detection area, control any one of the sensor or the camera to send a door closing signal, or control both the sensor and the camera to send a door closing signal.

[0080] In this way, the elevator control method of the present application can detect whether a target object is placed in the first detection area and send a door closing signal by setting a sensor or a camera in the elevator car.

[0081] Similarly, as Figure 4 shown, sensors can also be correspondingly set at the bottom or the top of the car corresponding to the second detection area to detect whether a target object is placed in the second detection area, and the camera can also be used to detect whether a target object is placed in the second detection area.

[0082] In one embodiment, only a sensor or a camera can be installed in the elevator car to detect whether a target object is placed in the second detection area, and when the sensor detects that a target object is placed in the second detection area, control the sensor to send a normally open door signal, and when the camera detects that a target object is placed in the second detection area, control the camera to send a normally open door signal.

[0083] In another embodiment, sensors and cameras can also be installed inside the elevator car to detect whether there is an object placed in the second detection area. When the sensors and cameras detect that there is an object placed in the second detection area, any one of the sensors or cameras is controlled to send a signal for keeping the door open, or both the sensors and cameras are controlled to send signals for keeping the door open.

[0084] In this way, the elevator control method of the present application can detect whether an object is placed in the second detection area and send a signal for keeping the door open by setting sensors or cameras inside the elevator car.

[0085] In some embodiments, the detection area in the car is dynamically divided based on requirements. That is to say, the detection area in the car of the present application can be dynamically divided based on the user's transportation requirements for the object. The setting of the detection area is more user-friendly and can meet the transportation requirements of different users for different objects.
