Technical Field

[0001] This application relates to the technical field of warehousing and transportation, and particularly relates to an elevator control method and device based on a car detection area. Background Art

[0002] Currently, in the elevator transportation system applied to multi-story warehouses, manual operation of the elevator to transport objects is the current mainstream mode. With the continuous increase in modern logistics demands and the continuous improvement of requirements for logistics efficiency, the elevator transportation system operated manually can no longer meet the transportation needs of modern logistics.

[0003] During the process of the elevator transporting objects, the elevator usually needs to be manually operated when it reaches the destination floor, which poses risks of human negligence and misoperation. At the same time, it also wastes manpower and time. Along with the continuous increase in modern logistics demands and the continuous improvement of requirements for logistics efficiency, the traditional freight elevator system can no longer meet the needs. Therefore, a more intelligent control system needs to be introduced. Summary of the Invention

Of course, they are only examples and are not intended to limit the present application.

[0034] Embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary only for explaining the present application and should not be construed as limiting the present application.

[0035] Please refer to Figure 1 , the present application provides an elevator control method based on a car detection area. The elevator control method includes:

[0036] 01: Obtain a feedback signal indicating that an object is placed in the elevator car, where the feedback signal is associated with a car detection area in the car, different car detection areas correspond to the same or different feedback signals, and the feedback signal includes destination floor information;

[0037] 02: Control the operation of the elevator based on the feedback signal.

[0038] Please combine with 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. The control module 11 is configured to obtain a feedback signal indicating that an object is placed in the elevator car, where the feedback signal is associated with a car detection area in the car, different car detection areas correspond to the same or different feedback signals, and the feedback signal includes destination floor information; and control the operation of the elevator based on the feedback signal.

[0039] Specifically, different car detection areas correspond to the same or different feedback signals, which means that different car detection areas can correspond to the same feedback signal, and different car detection areas can also correspond to different feedback signals. For example, the car detection areas include three areas A, B, and C. Areas A and B can correspond to the same feedback signal, and area C can correspond to a feedback signal different from that of areas A and B. For example, the feedback signals corresponding to areas A and B can both indicate the signal of running to the destination floor P1, where the feedback signals corresponding to areas A and B include the destination floor information with the destination floor being P1. 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 the signal indicating running to the destination floor P2, where the feedback signal corresponding to area C includes the destination floor information with the destination floor being P2.

[0040] The elevator control method of the present application can divide the elevator car into areas, and use a detection instrument to detect whether there is a target object placed in the detection area inside the elevator car. The target object can be an object such as goods or a robot, and there is no limitation here. When the detection instrument detects that a target object is placed in a certain detection area inside the elevator car, it can send out a feedback signal corresponding to this detection area, thereby controlling the elevator to run to different destination floors.

[0041] In this way, when there is a target object placed in the car detection area inside the elevator, the elevator control method of the present application can send out a feedback signal corresponding to this car detection area, and automatically control the elevator to run to the destination floor based on this feedback signal, realizing the action of manually triggering a button to control the destination floor of the elevator, which is simple and fast.

[0042] Please refer to Figure 3 , in some embodiments, the elevator control method includes:

[0043] 011: When at least one car detection area inside the elevator car is triggered by a target object, obtain the destination floor corresponding to the triggered car detection area;

[0044] 021: Control the elevator to transport the target object to the destination floor.

[0045] Please combine Figure 2 , steps 011 and 021 can be implemented by the control module 11. The control module 11 is used to obtain the destination floor corresponding to the triggered car detection area when at least one car detection area inside the elevator car is triggered by a target object; control the elevator to transport the target object to the destination floor.

[0046] Specifically, the target object can be a target object such as goods or a robot, and there is no limitation here.

[0047] At least one car detection area means that there is one or more car detection areas provided inside the car of the elevator. The car detection area is used to detect the placement state of the target object to trigger the control of the elevator to run to the destination floor corresponding to the car detection area. Among them, the placement state of the target object in the car detection area includes a first state where the target object is placed and a second state where the target object is not placed. Different car detection areas inside the elevator car can be divided into different functional areas that trigger the control of the elevator to run to different destination floors.

[0048] The elevator control method of this application can detect whether a target object is placed in the car detection area inside the elevator car, trigger the issuance of a feedback signal, and thus control the elevator to run to the destination floor corresponding to the car detection area based on the feedback signal.

[0049] The multiple car detection areas can be 2 car detection areas, 3 car detection areas, or 4 car detection areas, and there is no limitation here.

[0050] As Figure 4 shown, the area inside the elevator car is divided into 2 car detection areas, and the 2 car detection areas are Area A and Area B respectively. The function of Area A can be set to control the elevator to run to the destination floor P11 when it is detected that the target object is placed in Area A. The function of Area B can be set to control the elevator to run to the destination floor P12 when it is detected that the target object is placed in Area B.

[0051] As Figure 5 shown, the area inside the elevator car is divided into 3 detection areas, and the 3 car detection areas are Area A, Area B, and Area C respectively. The function of Area A can be set to control the elevator to run to the destination floor P3 when it is detected that the target object is placed in Area A. The function of Area B can be set to control the elevator to run to the destination floor P4 when it is detected that the target object is placed in Area B. The function of Area C can be set to control the elevator to run to the destination floor P5 when it is detected that the target object is placed in Area C.

[0052] As Figure 6 shown, the area inside the elevator car is divided into 4 car detection areas, and the 4 car detection areas are Area A, Area B, Area C, and Area D respectively. The function of Area A can be set to control the elevator to run to the destination floor P6 when it is detected that the target object is placed in Area A. The function of Area B can be set to control the elevator to run to the destination floor P7 when it is detected that the target object is placed in Area B. The function of Area C can be set to control the elevator to run to the destination floor P8 when it is detected that the target object is placed in Area C. The function of Area D can be set to control the elevator to run to the destination floor P9 when it is detected that the target object is placed in Area D.

[0053] Understandably, since the feedback signal is an electrical signal emitted when the car detection area is triggered by the target, and the car detection area corresponds to the destination floor, therefore, the feedback signal of the present application is an electrical signal with the car detection area and the corresponding destination floor information, and the elevator can be controlled according to the feedback signal to transport the target to the destination floor.

[0054] In this way, when the car detection area in the elevator is triggered by the target, the elevator control method of the present application obtains the destination floor corresponding to the triggered car detection area, so that the elevator can be automatically controlled to run to the destination floor corresponding to the car detection area, enabling the elevator to transport the target to the destination floor, realizing the action of automatically controlling the elevator to run to the destination floor without manually triggering the button to control the elevator, and can automatically control the elevator to run to the destination floor, which is simple and fast.

[0055] Please refer to Figure 7 , in some embodiments, the elevator control method includes:

[0056] 012: When multiple car detection areas in the elevator car are triggered by multiple targets, obtain the destination floors corresponding to each car detection area;

[0057] 022: Control the elevator to sequentially transport multiple targets to the corresponding destination floors according to the order of the destination floors.

[0058] Please combine Figure 2 , step 012 and step 022 can be implemented by the control module 11. The control module 11 is used to obtain the destination floors corresponding to each car detection area when multiple car detection areas in the elevator car are triggered by multiple targets; control the elevator to sequentially transport multiple targets to the corresponding destination floors according to the order of the destination floors.

[0059] Specifically, in one embodiment, when there are multiple car detection areas and each car detection area corresponds to 1 destination floor. For example, as Figure 6 shown, there are 4 car detection areas in the elevator car, namely area A, area B, area C, and area D. Area A corresponds to the destination floor P2, area B corresponds to the destination floor P3, area C corresponds to the destination floor P4, and area D corresponds to the destination floor P5. When there are targets placed in area A, area B, area C, and area D in the elevator car, that is, when triggered by multiple targets, the destination floors corresponding to each car detection area can be obtained, and the elevator can be controlled to sequentially transport multiple targets to the corresponding destination floors according to the order of the destination floors.

[0060] For example, if the priority order of the destination floors P2 to P5 can be sorted from first to last as P2 - P3 - P4 - P5, the elevator can be first controlled to run to the destination floor P2, then controlled to run to the destination floor P3, then controlled to run to the destination floor P4, and finally controlled to run to the destination floor P5.

[0061] In this way, when multiple car detection areas in the elevator car are triggered by multiple targets, the elevator control method of the present application obtains the destination floors corresponding to each car detection area, and controls the elevator to sequentially transport the multiple targets to the corresponding destination floors according to the order of the destination floors. The control logic is reasonable, and the elevator operation plan is simple and convenient.

[0062] The elevator of the present application described above can be always open or have no door body, which is convenient for directly unloading the target from the elevator car after the elevator transports the target to the destination floor. The elevator of the present application can also have a door body. Therefore, the opening and closing of the elevator can also be automatically controlled according to the feedback signal, so as to facilitate the unloading process after the elevator reaches the destination floor.

[0063] Please refer to Figure 8 , in some embodiments, step 022 includes:

[0064] 0221: When the first target is transported to the first destination floor, detect the first feedback signal corresponding to the first target;

[0065] 0222: In response to the failure of the first feedback signal, control the elevator to execute door closing or door closing countdown;

[0066] 0223: After the elevator closes the door, continue to transport the second target to the second destination floor, and control the elevator to execute door closing when the second feedback signal of the second destination floor fails; wherein, the first target and the second target are targets located in different car detection areas, and in the current running direction of the elevator, the first destination floor is the floor that arrives before the second destination floor;

[0067] 0224: Until all the feedback signals in the car fail to complete the transportation of all targets.

[0068] Please combine with Figure 2, Step 0221, Step 0222, Step 0223, and Step 0224 can be implemented by the control module 11. The control module 11 is used to detect the first feedback signal corresponding to the first target when the first target is transported to the first destination floor; in response to the failure of the first feedback signal, control the elevator to execute door closing or door closing countdown; after the elevator closes the door, continue to transport the second target to the second destination floor, and close the elevator door after the second feedback signal of the second destination floor fails; wherein, the first target and the second target are targets located in different car detection areas, and in the current running direction of the elevator, the first destination floor is the floor that arrives before the second destination floor; until all the feedback signals in the car fail to complete the transportation of all targets.

[0069] Specifically, in this application, when the elevator runs from the starting floor to the destination floor and the elevator door opens, before the target is removed from the car detection area corresponding to the destination floor, the feedback signal remains valid, and at this time, the elevator can be controlled to keep the door open constantly. After the target is removed from the car detection area corresponding to the destination floor, the feedback signal will fail, and at this time, control the elevator to execute door closing or door closing countdown.

[0070] It can be understood that after the elevator of this application reaches the destination floor, the elevator can automatically open the door, and before the target corresponding to the destination floor is completely removed from the car detection area, the feedback signal is valid, and the elevator also keeps the door open all the time. When the feedback signal fails, the elevator can be automatically controlled to close the door or perform door closing countdown, without manual control of the elevator door opening and closing.

[0071] In this way, this application can control the elevator to run to the destination floor according to the feedback signal corresponding to the target, then control the elevator to open the door for unloading, and automatically control the elevator to close the door after the feedback signal fails, realizing automatic control of the elevator door opening and closing, without manual control of the elevator door opening and closing.

[0072] In some embodiments, the method further includes:

[0073] 03: When the feedback signal in the car persists for a preset time, trigger a reminder message for target retention.

[0074] Please combine Figure 2 , Step 03 can be implemented by the control module 11. That is, the control module 11 is used to trigger a reminder message for target retention when the feedback signal in the car persists for a preset time.

[0075] Specifically, the preset time can be, for example, 5 min, 10 min, 11 min, 12 min, 13 min, 14 min, 15 min, 16 min, 17 min, 18 min, 19 min, or 20 min, and is not limited herein.

[0076] Understandably, since after each arrival at a destination floor, the target object corresponding to the car detection area is moved out to that destination floor, the feedback signal within the car detection area will become invalid. If the feedback signal within the car persists within a preset time, that is, remains continuously valid, it indicates that the target object may have been forgotten and remains in the elevator car all the time.

[0077] Therefore, when the time for the continuous validity of the car detection area signal detected by the elevator control method of this application reaches the preset time, a reminder message for the retention of the target object can be triggered, that is, the elevator can be controlled to give an alarm prompt. The alarm prompt can remind the transportation personnel through means such as audible and visual alarms and voice prompts that there is still a target object in the car, so as to avoid the situation where the elevator cannot respond to other operation tasks due to the target object being forgotten and remaining in the elevator car all the time, resulting in blockage of the target object.

[0078] In some embodiments, the elevator control method further includes:

[0079] 04: When the target object reaches the corresponding destination floor, control the car detection area of the corresponding destination floor to emit a signal lamp or voice prompt.

[0080] Please combine Figure 2 , step 04 can be implemented by the control module 11. That is, the control module 11 is used to control the car detection area of the corresponding destination floor to emit a signal lamp or voice prompt when the target object reaches the corresponding destination floor.

[0081] Specifically, when the target object reaches the corresponding destination floor, the car detection area of the target floor can be made to emit a signal lamp. The signal lamp can be a red, yellow, or green lamp, and there is no limitation here.

[0082] When the target object reaches the corresponding destination floor, the car detection area of the target floor can be made to emit a voice indication. The voice indication can be "The target object has reached the destination floor P1".

[0083] In this way, the elevator control method of this application can, when the target object reaches the corresponding destination floor, make the car detection area of the corresponding destination floor emit a signal lamp or voice prompt, thereby prompting the carrying personnel to unload the target object in the elevator car in a timely manner.

[0084] In some embodiments, one or more car detection areas correspond to one destination floor.

[0085] That is, when there is one or more car detection areas in the present application, one car detection area can correspond to one destination floor one by one. For example, when there is one car detection area in the elevator car, the car detection area is named Area A, and the destination floor corresponding to the car detection area A is P5, then when it is detected that there is an object placed in Area A in the elevator car, a feedback signal can be sent, and the elevator operation can be controlled to the destination floor P5 according to the feedback signal.

[0086] For another example, when there are multiple car detection areas in the elevator car, the car detection areas are respectively named Area A and Area B, the destination floor corresponding to Area A is P3, and the destination floor corresponding to Area B is P4, then when it is detected that there is an object placed in Area A in the elevator car, a feedback signal can be sent, and the elevator operation can be controlled to the destination floor P3 according to the feedback signal; when it is detected that there is an object placed in Area B in the elevator car, a feedback signal can be sent, and the elevator operation can be controlled to the destination floor P4 according to the feedback signal.

[0087] In addition, when there are multiple car detection areas in the present application, multiple car detection areas can correspond to one destination floor one by one. For example, when there are multiple car detection areas in the elevator car, the car detection areas are respectively named Area A and Area B, and the destination floors corresponding to both Area A and Area B are P4, then when it is detected that there is an object placed in Area A in the elevator car, a feedback signal can be sent, and the elevator operation can be controlled to the destination floor P4 according to the feedback signal; when it is detected that there is an object placed in Area B in the elevator car, a feedback signal can also be sent, and the elevator operation can be controlled to the destination floor P4 according to the feedback signal.

[0088] In this way, one or more car detection areas in the elevator control method of the present application can correspond to one destination floor, so that the destination floors corresponding to different car detection areas can be the same or different, meeting the transportation requirements of objects in different scenarios.

[0089] In some embodiments, at least one sensor is provided in each car detection area and / or a camera is provided in the car, and the elevator control method includes:

[0090] 05: When it is detected by the sensor that an object is placed in the car detection area, a feedback signal is sent;

[0091] Or,

[0092] 06: When it is detected by the camera that an object is placed in the car detection area, a feedback signal is sent;

[0093] Or,

[0094] When the target object is detected by both the sensor and the camera in the car detection area, a feedback signal is sent.

[0095] Please combine Figure 2 , Steps 05, 06 and 07 can be implemented by the control module 11. The control module 11 is used to send a feedback signal when the target object is detected by the sensor in the car detection area; send a feedback signal when the target object is detected by the camera in the car detection area; send a feedback signal when the target object is detected by both the sensor and the camera in the car detection area.

[0096] Specifically, the sensor can be, for example, an infrared sensor or other types of sensors, which is not limited here. As Figure 3 , Figure 4 or Figure 5 shown, the sensor can be set at the bottom or top of the car corresponding to the car detection area, which is not limited here. The number of sensors can be determined according to the number of car detection areas. For example, if the number of car detection areas is 2, the number of sensors corresponding to 1 car detection area can be 4, and the number of sensors corresponding to 2 car detection areas is 8, as Figure 4 shown.

[0097] The camera can be set on 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 car detection area, which is not limited here. The number of cameras can be 1 or more, which is not limited here.

[0098] 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 car detection area, and when the sensor detects that a target object is placed in the car detection area, control the sensor to send a feedback signal, and when the camera detects that a target object is placed in the car detection area, control the camera to send a feedback signal.

[0099] In another embodiment, a sensor and a camera can also be installed in the elevator car to detect whether a target object is placed in the first car detection area, and when the sensor and the camera detect that a target object is placed in the car detection area, control any one of the sensor or the camera to send a feedback signal, or control both the sensor and the camera to send feedback signals.

[0100] In this way, the elevator control method of the present application can detect whether a target object is placed in the car detection area and send a feedback signal by setting a sensor or a camera in the elevator car.

[0101] Please refer to Figure 9 , in some embodiments, Step 02 includes:

[0102] 023: Generate a call signal based on the destination floor information in the feedback signal;

[0103] 024: Control the elevator to run to the destination floor according to the call signal.

[0104] Please combine Figure 2 , step 023 and step 024 can be implemented by the control module 11. That is, the control module 11 is used to generate a call signal based on the destination floor information in the feedback signal; control the elevator to run to the destination floor according to the call signal.

[0105] Specifically, for example, the feedback signal includes the destination floor information as P2, P3, P4, and P5. The destination floor information corresponding to the car detection area A is P2, the destination floor information corresponding to the car detection area B is P3, the destination floor information corresponding to the car detection area C is P4, and the destination floor information corresponding to the car detection area D is P5. And the priority order of the destination floors P2 to P5 from first to last can be P2 - P3 - P4 - P5. Then the elevator can generate multiple call signals according to the priority order of different destination floors corresponding to different car detection areas, which are call signals S1, S2, S3, and S4 respectively. The call signal S1 is to control the elevator to run to the destination floor P2, the call signal S2 is to control the elevator to run to the destination floor P3, the call signal S3 is to control the elevator to run to the destination floor P4, and the call signal S4 is to control the elevator to run to the destination floor P5.

[0106] After generating multiple call signals, the elevator can be controlled to run to different destination floors in sequence according to the priority order of the destination floors according to the multiple call signals. That is, since the priority order of the destination floors P2 to P5 from first to last can be P2 - P3 - P4 - P5, the elevator can be controlled to run to the destination floor P2 according to the multiple call signals S1 to S4 first, then control the elevator to run to the destination floor P3, then control the elevator to run to the destination floor P4, and finally control the elevator to run to the destination floor P5.

[0107] Please refer to Figure 10 and Figure 11 , in some embodiments, the target object further includes out - of - warehouse information, and the out - of - warehouse information includes the destination floors corresponding to each target object; the method further includes:

[0108] Obtain the out - of - warehouse information of the target object;

[0109] 081: Generate a call signal based on the destination floor information in the out - of - warehouse information of the target object;

[0110] 091: Control the elevator to run to the destination floor according to the call signal; or

[0111] 082: Generate a call signal based on the destination floor information in the out-warehouse information of the target object and the feedback signal;

[0112] 092: Control the elevator to run to the destination floor according to the call signal.

[0113] Please combine Figure 2 , step 081, step 091, step 082 and step 092 can be implemented by the control module 11. That is, the control module 11 is used to generate a call signal based on the destination floor information in the out-warehouse information of the target object; control the elevator to run to the destination floor according to the call signal; or generate a call signal based on the destination floor information in the out-warehouse information of the target object and the feedback signal; control the elevator to run to the destination floor according to the call signal.

[0114] Specifically, in some embodiments, a call signal is generated based on the out-warehouse information of the target object, and the out-warehouse information includes the destination floor corresponding to each target object. The out-warehouse information may be the information that the target objects in a certain area of the warehouse leave the warehouse. The elevator control method of the present application can perform out-warehouse detection on the out-warehouse of the factory target objects according to the division of the target object storage areas in the factory and the floor setting rules for presetting the destination floors corresponding to different target object storage areas, so as to automatically trigger an out-warehouse signal when the target objects leave the warehouse. The out-warehouse signal includes the out-warehouse information of the target objects, so that the out-warehouse information can be obtained based on the out-warehouse signal.

[0115] It can be understood that in order to efficiently manage and track target objects within the factory, the division of target object storage areas usually divides the target object storage areas into different parts according to factors such as the type, size, weight, and demand frequency of the target objects. The division of the target object storage areas can be based on physical space, for example, based on different shelves, warehouses or areas to divide the target object storage areas. The division of the target object storage areas can also be based on logical classification, such as dividing the target object storage areas according to product lines, raw materials and finished products, etc.

[0116] Therefore, the present application can trigger different out-warehouse signals according to the division of the discharge areas of the target objects and the setting rules of the destination floors, so that it can be determined from different out-warehouse signals which target objects leave from which area and are transported to which floor. That is to say, the out-warehouse signal of the present application can be used to automatically identify the identity category of the target object, the storage location in the warehouse, and the corresponding destination floor to be reached, that is, the out-warehouse information of the target object can be obtained from the out-warehouse signal.

[0117] For example, in the out-of-warehouse information, the destination floor corresponding to the target Q1 is P2, the destination floor corresponding to the target Q2 is P3, the destination floor corresponding to the target Q3 is P4, and the destination floor corresponding to the target Q4 is P5. The destination floor information corresponding to the car detection area A is P2, the destination floor information corresponding to the car detection area B is P3, the destination floor information corresponding to the car detection area C is P4, and the destination floor information corresponding to the car detection area D is P5. And the priority order of the destination floors P2 to P5 from first to last can be P2 - P3 - P4 - P5. Then the elevator can generate multiple call signals according to the priority order of different destination floors corresponding to different car detection areas, which are call signals S1, S2, S3, and S4 respectively. The call signal S1 is to control the elevator to run to the destination floor P2, the call signal S2 is to control the elevator to run to the destination floor P3, the call signal S3 is to control the elevator to run to the destination floor P4, and the call signal S4 is to control the elevator to run to the destination floor P5.

[0118] After generating multiple call signals, the elevator can be controlled to run to different destination floors in sequence according to the priority order of the destination floors based on the multiple call signals. That is, since the priority order of the destination floors P2 to P5 from first to last can be P2 - P3 - P4 - P5, the elevator can be controlled to run to the destination floor P2 first according to the multiple call signals S1 to S4, then controlled to run to the destination floor P3, then controlled to run to the destination floor P4, and finally controlled to run to the destination floor P5.

[0119] In this way, the elevator control method of the present application can not only directly generate call signals based on the destination floor information in the feedback signal, but also generate call signals according to the out-of-warehouse information of the target, so as to control the elevator to run to the destination floor according to the call signals, and the control method is more diversified.

[0120] In other embodiments of the present application, call signals can be generated simultaneously based on the out-of-warehouse information of the target and the destination floor information in the feedback signal, and the elevator can be controlled to run to the destination floor more accurately according to the generated call signals. That is, the elevator control method of the present application can also generate call signals more accurately by combining the destination floor information in the feedback signal with the out-of-warehouse information of the target, so as to control the elevator to run to the destination floor according to the call signal.
