[0001] The present application relates to the field of warehousing and transportation technology, and in particular to an elevator control method and device based on a car detection area. Background Art

[0002] Currently, manually operated elevators are the mainstream mode of transporting objects in multi-story warehouses. With the increasing demand for modern logistics and the increasing demand for logistics efficiency, manually operated elevator systems can no longer meet the transportation needs of modern logistics.

[0003] When transporting objects in an elevator, closing the elevator door usually requires manual operation, which poses the risk of human negligence and misoperation, and also wastes manpower and time. At the same time, with the continuous increase in modern logistics needs and the continuous improvement in the requirements for logistics efficiency, the traditional freight elevator system can no longer meet the needs, so a more intelligent control system needs to be introduced.

[0008] In certain embodiments, the number of the first detection zone is one or more, and / or the number of the second detection zone is one or more.

[0009] In some embodiments, there is one first detection area and one or more second detection areas; the elevator control method further includes: when the target object needs to be placed in the elevator car multiple times, upon detecting that the target object is first placed in the second detection area, the elevator door is controlled to be normally open based on the normally open door signal; after detecting that the remaining target objects are placed in the first detection area, the elevator door is controlled to be closed based on the door closing signal.

[0010] In some embodiments, the elevator control method includes: when it is detected that the target object is placed in any one of the multiple second detection areas, issuing the normally open door signal, and controlling the elevator normally open door according to the normally open door signal; or when it is detected that the target object is placed in multiple second detection areas at the same time, issuing multiple normally open door signals at the same time, and controlling the elevator normally open door according to the multiple normally open door signals; or when it is detected that the target object is placed in the first detection area, issuing the door closing signal, and controlling the elevator door to close according to the door closing signal.

In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, these are merely examples and are not intended to limit the present application.

[0029] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and should not be understood as limiting the present application.

[0030] See also Figure 1 The present application provides an elevator control method based on a car detection area. The elevator control method includes:

[0031] 01: Acquire feedback signals when a target is placed in an elevator car. The feedback signals are associated with detection zones in the car. Different detection zones correspond to the same or different feedback signals. The feedback signals include door closing signals and / or door open signals.

[0032] 02: Control the elevator operation based on the feedback signal.

[0033] See also Figure 2 The present application further provides an elevator control device 10 based on a car detection area. The elevator control device 10 includes a control module 11.

[0034] Steps 01 and 02 can be implemented by the control module 11. The control module 11 is configured to obtain a feedback signal indicating that a target object is placed in the elevator car, wherein 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 door normally open signal; and control the operation of the elevator based on the feedback signal.

[0035] Specifically, the feedback signal includes a door closing signal and / or a normally open door signal, specifically including the following three situations: (1) the feedback signal includes a door closing signal; (2) the feedback signal includes a normally open door signal; (3) the feedback signal includes both a door closing signal and a normally open door signal. This application can control the elevator door to close based only on the door closing signal, can control the elevator door to be normally open based only on the normally open door signal, or can control the elevator door to close or be normally open based on both the door closing signal and the normally open door signal.

[0036] Different detection areas correspond to the same or different feedback signals. This means that different detection areas can correspond to the same feedback signal or different feedback signals. For example, the detection areas in the elevator 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 can correspond to a different feedback signal from areas A and B, and the feedback signal corresponding to area C can be a closed door signal.

[0037] In other words, the elevator control method of the present application can divide the elevator car into zones and use a detection instrument to detect whether a target object is placed in a detection zone within the elevator car. The target object can be an object such as cargo or a robot, without limitation. When the detection instrument detects a target object in a detection zone within the elevator car, it can send a feedback signal corresponding to the detection zone, thereby controlling the elevator door to close or remain open.

[0038] In this way, the elevator control method of the present application can send a feedback signal corresponding to the detection area when a target object is placed in the detection area inside the elevator, and automatically control the elevator door to close or remain open based on the feedback signal, so that there is no need to manually trigger the elevator closing or opening action, and there is no need to detect whether the elevator car is fully loaded. The elevator door can be automatically controlled to remain open or closed, which is simple and fast.

[0039] See also Figure 3 , this application provides an elevator control method. The elevator control method includes:

[0040] 011: When a target is detected to be placed in the first detection area in the elevator car, a door closing signal is issued; wherein, the elevator car is provided with one or more detection areas, and the detection areas are used to detect the placement status of the target to control the elevator door to close or keep it open;

[0041] 021: Control the elevator door to close according to the door closing signal.

[0042] Please combine Figure 2 Steps 011 and 021 can be implemented by the control module 11. The control module 11 is configured to send a door closing signal when detecting that a target object is placed in a first detection area in the elevator car; wherein the elevator car is provided with one or more detection areas, and the detection areas are configured to detect the placement of the target object to control the elevator door to close or remain open; and to control the elevator door to close according to the door closing signal.

[0043] Specifically, the placement state of the target object in the detection area includes a first state where the target object is placed and a second state where the target object is not placed.

[0044] An elevator car can be equipped with a detection area to detect the placement of an object and control whether the elevator door is closed or open. When a detection area is set within the elevator car, it can be a portion of the elevator car area. The location of the detection area can be set by default or customized according to user needs, without any restrictions.

[0045] The elevator car can also be equipped with multiple detection areas, which are used to detect the placement of objects to control whether the elevator door is closed or open. This means that by detecting whether objects are placed in different areas of the elevator car, the elevator door can be controlled to open or close. In other words, different areas of the elevator car can be divided into different functional areas for controlling the opening or closing of the elevator door.

[0046] The multiple detection areas may be 2 detection areas, 3 detection areas, or 4 detection areas, which is not limited here.

[0047] like Figure 4 As shown, the elevator car is divided into two detection areas, Area A and Area B. Area A can be set to control the elevator door to remain open when an object is detected in Area A. Area B can be set to control the elevator door to close when an object is detected in Area B.

[0048] like Figure 5 As shown, the elevator car interior is divided into three detection zones: Zone A, Zone B, and Zone C. Zone A can be configured to keep the elevator door open when an object is detected in Zone A. Zone B can be configured to keep the elevator door open when an object is detected in Zone B. Zone C can be configured to close the elevator door when an object is detected in Zone C.

[0049] like Figure 6 As shown, the area inside the elevator car is divided into four detection areas: Area A, Area B, Area C, and Area D. The function of Area A can be set to control the elevator door to remain open when a target is detected in Area A. The function of Area B can be set to control the elevator door to remain open when a target is detected in Area B. The function of Area C can be set to control the elevator door to remain open when a target is detected in Area C. The function of Area D can be set to control the elevator door to remain open when a target is detected in Area D.

[0050] The first detection area is the functional area in the elevator car that can control the closing of the elevator door. For example, the first detection area can be Figure 4 In the B area, Figure 5 The C region and Figure 6 The door closing signal can be a current or voltage signal, which is not limited here.

[0051] In addition, the first detection area can be set within a preset area range in the elevator car close to the elevator door body, and the first detection area can also be set within a preset area range in the elevator car close to the elevator side wall.

[0052] In this way, the elevator control method of the present application can automatically control the elevator door to close when a target object is placed in the first detection area in the elevator, without manually triggering the elevator closing or opening action, and without detecting whether the elevator car is fully loaded. The elevator door can be automatically controlled to close, which is simple and fast.

[0053] See also Figure 7 In some embodiments, the elevator control method includes:

[0054] 012: When a target object is detected in the second detection area in the elevator car, a normally open door signal is issued; wherein, the elevator car is provided with one or more detection areas, and the detection areas are used to detect the placement status of the target object to control the elevator door to close or normally open the door;

[0055] 022: Control the elevator door to be normally open according to the normally open door signal.

[0056] Please combine Figure 2 , steps 012 and 022 can be implemented by the control module 11. That is, the control module 11 is configured to issue a normally open door signal when detecting that the target object is in the second detection area in the elevator car; wherein the elevator car is provided with one or more detection areas, the detection areas being configured to detect the placement of the target object to control the elevator door to close or normally open; and to control the elevator door to normally open according to the normally open door signal.

[0057] Specifically, the second detection area is a functional area in the elevator car that can control the elevator door to be normally open. For example, the second detection area can be Figure 4 In area A, Figure 5 Area A and Area B in Figure 6 The door closing signal may be an electrical signal.

[0058] In this way, the elevator control method of the present application can automatically control the elevator door to remain open when a target object is placed in the second detection area in the elevator, so that there is no need to manually trigger the action of keeping the elevator door open, and there is no need to detect whether the elevator car is fully loaded. The elevator can be automatically controlled to keep the door open, which is simple and fast.

[0059] In some embodiments, there are one or more first detection areas, and / or one or more second detection areas. That is, the division of the first detection area and the second detection area may include the following situations: (1) there is one first detection area and one second detection area; (2) there is one first detection area and multiple second detection areas; (3) there are multiple first detection areas and one second detection area; (4) there are multiple first detection areas and multiple second detection areas.

[0060] Specifically, the number of the first detection areas can be 1, 2 or 3, which is not limited here. When the number of the first detection area is 1, for example, the first detection area can be Figure 4 In the B area, Figure 5 The C region and Figure 6 Similarly, the number of the second detection areas can be 1, 2 or 3, which is not limited here.

[0061] It should be noted that the elevator car of the present application may further be divided into other placement areas without functional detection, or may only be provided with a first detection area and a second detection area.

[0062] The division method of the first detection area and the second detection area in the elevator car in the elevator control method of the present application is more flexible and can be applied to different application scenarios.

[0063] It is understood that when there are multiple first detection areas, the elevator door can be controlled to close as soon as an object is detected in any of the first detection areas. Furthermore, the elevator door can be controlled to close if objects are detected in multiple first detection areas simultaneously. If objects are detected in multiple first detection areas sequentially, the elevator door can be controlled to close only after the object is placed in the last first detection area.

[0064] See also Figure 8 In some embodiments, the first detection area is one, and the second detection area is one or more. The elevator control method further includes:

[0065] 023: When the target object needs to be placed in the elevator car multiple times, the target object is first placed in the second detection area after being detected, and the elevator door is controlled to be normally open based on the normally open door signal;

[0066] 024: After continuing to detect the remaining target objects placed in the first detection area, the elevator door is controlled to close based on the door closing signal.

[0067] Please combine Figure 2 Steps 023 and 024 can be implemented by the control module 11. That is, when the target object needs to be placed in the elevator car multiple times, the control module 11 is configured to control the elevator door to be normally open based on the normally open door signal when the target object is first detected to be placed in the second detection area; and control the elevator door to be closed based on the door closing signal after the remaining target objects are detected to be placed in the first detection area.

[0068] Specifically, the elevator car area is divided into a first detection area and a second detection area, and there is one first detection area and one or more second detection areas.

[0069] In this case, if the target object needs to be placed in the elevator car multiple times, after detecting that the target object is first placed in one or more second detection areas, a normally open door signal corresponding to the second detection area can be issued, and the elevator door can be controlled to normally open according to the normally open door signal. After detecting that the remaining target objects are placed in the first detection area, a door closing signal corresponding to the first detection area can be issued, and the elevator door can be controlled to close according to the door closing signal.

[0070] In this way, the elevator control method of the present application can simultaneously set up one or more second detection areas and one first detection area in the elevator car. Therefore, when the number of target objects is large and needs to be placed in the elevator car multiple times, the target objects can be placed in the second detection area first, and the elevator door can be automatically controlled to be open. Then, the remaining target objects can be placed in the first detection area, thereby automatically controlling the elevator door to be closed.

[0071] In some embodiments, an elevator control method includes:

[0072] 03: When a target object is detected in any of the second detection areas, a door opening signal is issued, and the elevator door is controlled to be normally open according to the normally open door signal; or

[0073] 04: When multiple second detection areas are detected with objects placed thereon, multiple normally open door signals are sent out simultaneously, and the elevator door is controlled to normally open according to the multiple normally open door signals; or

[0074] 05: When it is detected that the target objects are placed in the first detection area one after another, a door closing signal is issued, and the elevator door is controlled to close according to the last door closing signal issued.

[0075] Please combine Figure 2 Step 03, step 04, and step 05 can be implemented by the control module 11. The control module 11 is configured to, when detecting that a target object is placed in any of the multiple second detection areas, issue a door-opening signal, and control the elevator door to be normally open according to the normally-open door signal; or, when detecting that a target object is placed in multiple second detection areas at the same time, issue multiple normally-open door signals at the same time, and control the elevator door to be normally open according to the multiple normally-open door signals; or, when detecting that a target object is placed in the first detection area successively, issue a door-closing signal, and control the elevator door to be closed according to the last door-closing signal issued.

[0076] Specifically, when a target is detected in any of the multiple second detection areas, a normally open door signal is issued, and the elevator door is controlled to normally open according to the normally open door signal. As long as a target is detected in any of the second detection areas in the multiple first detection areas, the elevator door can be controlled to normally open.

[0077] When objects are detected in multiple second detection areas simultaneously, multiple normally open door signals are issued simultaneously, and the elevator door is controlled to normally open according to the multiple normally open door signals. For example, if the object is large and the second detection area is small, and the object is placed in two second detection areas at the same time, the two second detection areas can trigger the issuance of normally open door signals simultaneously. In this case, the elevator door can be controlled to normally open according to the two normally open door signals issued by the two second detection areas.

[0078] When it is detected that a target object is placed in the only first detection area in the elevator car, a door closing signal is sent, and the elevator door is controlled to close according to the door closing signal. In other words, as long as a target object is placed in the first detection area, the elevator door can be immediately controlled to close.

[0079] Specifically, in some embodiments, the time interval between the door closing signal and the elevator door closing can be set to a preset time. For example, the preset time can be 1 second, 2 seconds, or 3 seconds. 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 pinched by the elevator door.

[0080] In this way, the method of dividing the second detection area 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 of carrying targets of different sizes or types.

[0081] In certain embodiments, when an elevator car has multiple first detection areas, multiple door closing signals are issued sequentially upon detecting objects placed successively in the multiple first detection areas, and the elevator door is closed based on the last issued door closing signal. For example, if the number of objects is large and the second detection area is full, and objects are placed successively in two first detection areas, the two first detection areas will trigger two door closing signals. In this case, the elevator door can be closed based on the second door closing signal triggered by the first detection area where the object was last placed, without the elevator door responding to the first door closing signal.

[0082] In detail, for example, the time interval between the door closing signal and the start of the elevator door closing can be set to 2S. If no new door closing signal is received within 2S, the elevator is controlled to close the door directly. If a new door closing signal is received within 2S, the elevator is controlled to wait for 2S before closing the door, and so on. In this way, when multiple door closing signals are sent successively, the elevator door can be controlled to close according to the last door closing signal sent.

[0083] In this way, the method of dividing the first detection area 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 of carrying targets of different sizes or types.

[0084] It should be noted that when the elevator control method of the present application has multiple second detection areas, it can be set to control the elevator to keep the door open as long as a target object is detected in one second detection area and no target object is placed in the first detection area.

[0085] In some embodiments, an elevator control method includes:

[0086] 06: Control the elevator to issue a door closing prompt based on the door closing signal.

[0087] See also 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 issue a door closing prompt according to the door closing signal.

[0088] Specifically, for example, controlling the elevator to issue a door closing prompt according to the door closing signal may be controlling the elevator internal call and / or elevator external call to issue a door closing prompt according to the door closing signal.

[0089] Controlling the elevator internal call and / or elevator external call to issue a door closing prompt according to the door closing signal includes the following situations: (1) controlling only the elevator internal call to issue a door closing prompt according to the door closing signal; (2) controlling only the elevator external call to issue a door closing prompt according to the door closing signal; (3) controlling both the elevator internal call and the elevator external call to issue a door closing prompt according to the door closing signal.

[0090] It can be understood that when a target object is detected and placed in the first detection area, the elevator internal call or elevator external call is controlled according to the door closing signal to issue a door closing prompt, which can remind the user that the elevator door is about to close at this time, thereby avoiding the user from being trapped in the elevator.

[0091] The door closing prompt may be, for example, a voice prompt, a text prompt, or a flashing light prompt, without limitation. The voice prompt may be, for example, a voice announcement of "The elevator door is about to close, please pay attention," without limitation.

[0092] In this way, when the elevator control method of the present application controls the elevator door to close according to the door closing signal, a door closing prompt can be issued to remind the user that the elevator door is about to close, thereby avoiding the occurrence of a ladder trap incident.

[0093] In addition, similarly, the elevator control method of the present application can also control the elevator internal call and / or elevator external call to issue a normally open door prompt based on the normally open door signal, thereby notifying the user that the elevator is in the normally open door state, so that the user can know the current open and closed state of the elevator door. The normally open door prompt can be, for example, a voice prompt, a text prompt, or a flashing light prompt, without limitation. The voice prompt can be, for example, a voice broadcast of "The elevator door is in the normally open door state, please pay attention", without limitation.

[0094] In some embodiments, at least one sensor is provided in each detection area and / or a camera is provided in the elevator car, and the elevator control method includes:

[0095] 071: When a sensor detects that a target object is placed in the detection area, the feedback signal is sent; or,

[0096] 072: When the camera detects that a target object is placed in the detection area, the feedback signal is sent; or,

[0097] 073: When the sensor and the camera simultaneously detect that the target object is placed in the detection area, the feedback signal is sent.

[0098] Please combine Figure 2 Step 071, step 072, and step 073 can be implemented by the control module 11. That is, the control module 11 is further configured to send the feedback signal when the sensor detects that the target is placed in the detection area; or send the feedback signal when the camera detects that the target is placed in the detection area; or send the feedback signal when the sensor and the camera simultaneously detect that the target is placed in the detection area.

[0099] Specifically, the sensor may be, for example, an infrared sensor or other types of sensors, which are not limited here. Figure 4 、 Figure 5 or Figure 6 As shown, the sensor can be set at the bottom or 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 first detection areas. For example, if the number of first detection areas is 2, the number of sensors corresponding to one first detection area can be 4, and the number of sensors corresponding to two first detection areas can be 8. Figure 5 shown.

[0100] The camera can be installed on the top of the elevator car or on the side wall of the elevator car, as long as it can capture whether the target object is placed in the first detection area. There is no limitation here. The number of cameras can be one or more, and there is no limitation here.

[0101] In one embodiment, the elevator car may only be installed with a sensor or a camera 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, the sensor is controlled to send a door closing signal, and when the camera detects that a target object is placed in the first detection area, the camera is controlled to send a door closing signal.

[0102] In another embodiment, sensors and cameras may be installed in the elevator car to detect whether a target object is placed in the first detection area. When the sensor and camera detect that a target object is placed in the first detection area, either the sensor or the camera is controlled to send a door closing signal, or both the sensor and the camera are controlled to send a door closing signal.

[0103] In this way, the elevator control method of the present application can detect whether the target object is placed in the first detection area and send a door closing signal by setting a sensor or camera in the elevator car.

[0104] Similarly, if Figure 4 As shown, a sensor may be provided at the bottom or top of the car corresponding to the second detection area to detect whether a target object is placed in the second detection area, and a camera may also be used to detect whether a target object is placed in the second detection area.
