Description

RELATED APPLICATIONS

[0001] This application claims priority to Chinese Patent Application No. 202211627794.5 filed with the China National Intellectual Property Administration (CNIPA) on Dec. 16, 2022, the disclosure of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the technical field of elevators, for example, a signal priority determination method and apparatus, an electronic device, and a storage medium. BACKGROUND [0002a] It is to be appreciated that any discussion of documents, devices, acts or knowledge in this specification is included to explain the context of the present invention. Further, the discussion throughout this specification comes about due to the realisation of the inventor and / or the identification of certain related art problems by the inventor. Moreover, any discussion of material such as documents, devices, acts or knowledge in this specification is included to explain the context of the invention in terms of the inventor’s knowledge and experience and, accordingly, any such discussion should not be taken as an admission that any of the material forms part of the prior art base or the common general knowledge in the relevant art in Australia, or elsewhere, on or before the priority date of the disclosure and claims herein.

[0003] In the related art, an elevator rider movement trend detection system sends a door machine opening or closing signal to an elevator door control system based on a rider movement trend, and the elevator door control system controls an elevator door to open or close according to a received door machine control signal. The elevator door control system simultaneously receives opening or closing signals from multiple sources, including the elevator rider movement trend detection system and an elevator internal and external call system. When there are both a door closing signal and a door opening signal, an elevator tends to delay closing or open the 2023396368   06 Aug 2026 elevator door in response to the door opening signal first. Even when an elevator car is fully loaded, the elevator still responds to the door opening signal. This single signal response mode is not only unreasonable but also prone to reducing the operating efficiency of an elevator system. Moreover, the elevator door control system receives door machine control signals from multiple sources, which is highly likely to confuse the control logic of a door machine. SUMMARY

[0021] To enable those skilled in the art to better understand technical solutions of the present application, the technical solutions in embodiments of the present application are clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0022] Embodiment one

[0023] FIG. 1 is a flowchart of a signal priority determination method according to embodiment one of the present application. This embodiment is applicable to the case of sorting the priority of a door opening signal and the priority of a door closing signal for an elevator. The method may be executed by a signal priority determination apparatus. The signal priority determination apparatus may be implemented in the form of hardware and / or software and configured in an electronic device. As shown in FIG. 1, the signal priority determination method includes the steps below.

[0024] In S101, an image of a detection region is collected, where the detection region includes an out-of-hall region of an elevator and a car region of the elevator.

[0025] The elevator may be provided with a sensor for collecting the image of the detection region. At least two sensors may be provided. The sensors are located in the out-of-hall region and the car region respectively. When two sensors are provided, the sensors may be located above 2023396368  07 Jul 2025 a car door, with one sensor facing the out-of-hall region and the other sensor facing the car region, so as to collect images of different regions respectively. Moreover, when the car door is closed, the included angle and distance between the sensor facing the car region and the car door are large, which can avoid being affected by the high reflectivity of the car door and ensure the quality of the images. Certainly, one sensor may also be provided. The viewing angle of the sensor may be determined according to the door state of the car door. When the door state of the car door is an open state, the viewing angle of the sensor is directed toward the out-of-hall region, and when the door state of the car door is a closed state, the viewing angle of the sensor is directed toward the car region. The number and the arrangement of sensors are not limited in this embodiment. It is to be noted that when one sensor is provided, detection ranges of the sensor when the sensor is directed toward the out-of-hall region and the car region may include a region in which the elevator door is located. The elevator door includes a hall door of the elevator and the car door of a car, so as to collect object information of objects entering and exiting the car when the objects pass through the elevator door.

[0026] It is to be noted that the present application is applicable to the case where in the process in which the elevator door is from being opened fully to being closed to a certain extent (that is, when the elevator door is closed to this extent, the sensor can just capture the image of the out-of-hall region; if the elevator door is further closed, the image of the out-of-hall region cannot be captured), whether to open the elevator door in the opposite direction is determined according to the conditions of the out-of-hall region of the elevator and the car region of the elevator.

[0027] In S102, object information of objects using the elevator in the detection region is determined according to the image.

[0028] The objects are usually riders, but may also be robots, pets, large items, or others.

[0029] The objects using the elevator may be objects that have entered the car, and the object information may include the number of in-car objects in the car region. The objects using the elevator may also be objects that wait for the elevator outside a hall, and the object information may also include the number of elevator-waiting objects. 2023396368  07 Jul 2025

[0030] The objects can be recognized by inputting the image into a trained object recognition model, thereby obtaining the number of in-car objects and the number of elevator-waiting objects.

[0031] In S103, the priority of a door opening signal and the priority of a door closing signal are determined for an elevator door of the elevator according to the object information.

[0032] The door opening signal of the elevator door is generated in the following manner.

[0033] Movement trends of the objects are determined according to an image of the out-of-hall region; when the movement trends of the objects are from the out-of-hall region to the elevator door, and / or when an out-of-hall call button is pressed, the door opening signal of the elevator door is generated. The movement trends of the objects may be detected by a movement trend detection model. When the movement trends of the objects are from the out-of-hall region to the elevator door, and / or when the out-of-hall call button is pressed, these may be regarded that the objects are ready to use the elevator, that is, an out-of-hall call. It is to be noted that the door opening signal excludes a door opening signal generated when a door opening button inside the car is pressed and is limited to a door opening signal generated when the out-of-hall call is detected.

[0034] The door closing signal of the elevator door may be a door closing signal generated when an object in the car region presses a door closing button or may be a door closing signal generated when the door opening time of the elevator door expires.

[0035] Determining the priority of the door opening signal and the priority of the door closing signal for the elevator door of the elevator according to the object information may include: determining whether the number of in-car objects reaches the rated capacity of the car of the elevator; in response to the number of in-car objects reaching the rated capacity of the car of the elevator, determining that the priority of the door closing signal is higher than the priority of the door opening signal for the elevator door of the elevator; and in response to the number of in-car objects not reaching the rated capacity of the car of the elevator, determining that the priority of the door opening signal is higher than the priority of the door closing signal. 2023396368  07 Jul 2025

[0036] Determining the priority of the door opening signal and the priority of the door closing signal for the elevator door of the elevator according to the object information may further include: first determining the full load degree of the car of the elevator according to the object information and then determining the priority of the door opening signal and the priority of the door closing signal for the elevator door of the elevator according to the full load degree of the car.

[0037] According to the number of in-car objects and the object types of the objects in the object information, the full load degree of the car may be determined according to the object types of the objects in the car region based on the determination of the number of in-car objects. The object types may have an additive effect on the full load degree of the car. Exemplarily, under the premise of loading the same number of objects (riders), since an elderly person cannot be squeezed by the crowd and needs to occupy more space, it can be considered that the full load degree of the car is applied with an additive effect when the object is the elderly person, that is, the full load degree of the car including at least one elderly person and the full load degree of the car only including young people are different.

[0038] After the full load degree of the car of the elevator is determined, if the car is fully loaded, it can be determined that the priority of the door closing signal is higher than the priority of the door opening signal for the elevator door of the elevator; if the car is not fully loaded, it can be determined that the priority of the door opening signal is higher than the priority of the door closing signal for the elevator door of the elevator.

[0039] In the signal priority determination method provided in the embodiment of the present application, the image of the detection region is collected, where the detection region includes the out-of-hall region of the elevator and the car region of the elevator; the object information of the objects using the elevator in the detection region is determined according to the image, where the object information includes the number of in-car objects in the car region and the object types of the in-car objects; and the priority of the door opening signal and the priority of the door closing signal are determined for the elevator door of the elevator according to the object information. When the priority of the door opening signal and the priority of the door closing signal are 2023396368  07 Jul 2025 determined, the door closing signal can be first responded to when the number of in-car objects reaches the rated capacity, thereby improving the operating efficiency of an elevator system. Moreover, the full load degree of the car can also be determined according to the object types of the objects in the car region, and when objects of different object types are present in the car, different full load degrees of the car can be obtained so that the full load degree of the car can be determined more reasonably. Consequently, in the elevator system that controls the door machine based on the elevator rider movement trend detection system, the control logical confusion of the door machine can be solved, and the control logic can be optimized so that the priority of the door opening signal and the priority of the door closing signal can be processed more reasonably.

[0040] Embodiment two

[0041] FIG. 2 is a flowchart of a signal priority determination method according to embodiment two of the present application. The embodiment of the present application is refined based on the preceding embodiment one. As shown in FIG. 2, the signal priority determination method includes the steps below.

[0042] In S201, the image of the detection region is collected, where the detection region includes the out-of-hall region of the elevator and the car region of the elevator.

[0043] S201 may refer to S101 in embodiment one and is not described herein.

[0044] In S202, whether objects in the out-of-hall region are located within a preset region range is determined according to the image.

[0045] The preset region range belongs to the out-of-hall region. Positions of the objects in the out-of-hall region are determined according to the image, and then whether the objects are located within the preset region range is determined according to the positions of the objects.

[0046] The preset region range of the out-of-hall region may be a region range in the out-ofhall region that has the midpoint of a lower edge of the elevator door as the center and the preset distance as the radius, or may also be a range in which a queuing region of the elevator is located. Whether the objects in the out-of-hall region are located within the preset region range is 2023396368  07 Jul 2025 determined according to the image. S203 is executed in response to the objects in the out-of-hall region being located within the preset region range. S204 is executed in response to the objects in the out-of-hall region not being located within the preset region range.

[0047] In S203, the objects are determined as elevator-waiting objects.

[0048] The elevator-waiting objects are objects that are ready to use the elevator and are located in the out-of-hall region, that is, an elevator-waiting hall. However, the range of the out-of-hall region that can be captured by the sensor may be large, for example, including a region of the hall, where a pedestrian may pass by but is not ready to use (take) the elevator; in addition, the out-ofhall region may also be a shared region for multiple elevators at the same time. Therefore, an object located in the out-of-hall region is not necessarily an object that is ready to use the elevator. An object is determined as the elevator-waiting object when the object in the out-of-hall region is located within the preset region range.

[0049] In S204, movement trends of the objects are recognized.

[0050] In S205, the objects are determined as the elevator-waiting objects when the movement trends of the objects are from the out-of-hall region to the elevator door.

[0051] If an object in the out-of-hall region does not belong to the preset region range of the out-of-hall region, but the movement trend of the object is from the out-of-hall region to the elevator door, it means that the object is ready to use the elevator, so the object may be determined as an elevator-waiting object.

[0052] The movement trend of the object may be recognized by a movement trend detection model or may also be determined in the following manner.

[0053] Position points of the object in collection cycles are acquired, distances from the position points to the elevator door are calculated, and the distance difference between two adjacent distances is calculated. When multiple consecutive distance differences are larger than a preset distance value, it is determined that the movement trend of the object is from the out-of-hall region to the elevator door. 2023396368  07 Jul 2025

[0054] It is to be noted that the distance difference between the two adjacent distances refers to the distance corresponding to the previous collection cycle minus the distance corresponding to the current collection cycle, and the preset distance value is a positive number. The condition that the multiple consecutive distance differences are larger than the preset distance value is configured herein to distinguish the situation where the object is close to the elevator but is not ready to use the elevator. For example, when the object is ready to use the elevator, the object usually walks straight to the elevator, and the distance difference between the two adjacent distances is large; and when the object is not ready to use the elevator, for example, the object is just ready to pass a path beside the elevator or takes an elevator opposite the elevator (different elevators may reach different floors), the object does not walk straight to the elevator, and the distance difference between the two adjacent distances is small. The preset distance value may be configured according to the road layout of the out-of-hall region, the position of the elevator in the out-of-hall region, and others, which is not limited in this embodiment.

[0055] When it is determined that the movement trend of the object is from the out-of-hall region to the elevator door, it can be determined that the object is ready to use the elevator, that is, the object is determined as the elevator-waiting object.

[0056] In S206, the number of the elevator-waiting objects is calculated.

[0057] The number of the elevator-waiting objects is obtained by counting.

[0058] In S207, when the number of in-car objects is located within a preset first interval, the priority of the door opening signal is determined to be higher than the priority of the door closing signal for the elevator door of the elevator.

[0059] In this embodiment, three intervals are configured as a parameter to measure the full load degree of the car. The three intervals are the preset first interval, a preset second interval, and a preset third interval respectively. The values of the three intervals are sorted in ascending order, that is, a value in the preset first interval is smaller than a value in the preset second interval, and the value in the preset second interval is smaller than a value in the preset third interval. For example, the ranges of the three intervals may be configured according to the elevator-riding 2023396368  07 Jul 2025 comfort of the elevator, the rated capacity of the elevator, and others. Exemplarily, when the rated capacity of the car of the elevator is 12 people, the first interval is configured as [0, 5], the second interval is configured as [6, 10], and the third interval is configured as [11, 12]. The third interval may also be the rated capacity of the car.

[0060] For ease of understanding, the full load degree of the car may be divided into three levels: low, moderate, and high, and the values of the number of in-car objects correspond to the three intervals respectively.

[0061] When the number of in-car objects is located within the preset first interval, it means that the full load degree of the car is low. To improve the utilization rate of the elevator, the elevator-waiting objects can be allowed to enter the car in this case. Therefore, the priority of the door opening signal is determined to be higher than the priority of the door closing signal for the elevator door of the elevator.

[0062] In S208, when the number of in-car objects is located within the preset second interval, the priority of the door opening signal and the priority of the door closing signal are determined according to the object types of the objects in the car region and the number of elevator-waiting objects.

[0063] When the number of in-car objects is located within the preset second interval, it means that the full load degree of the car is moderate, that is, the environment in the elevator is relatively spacious, and there is space to accommodate the elevator-waiting objects. In the related art, to improve the utilization rate of the elevator, the elevator-waiting objects can be allowed to enter the car in this case, but in this embodiment, when the full load degree of the car is moderate, the object types of the objects in the car region are also taken into account, and the object types are used as another parameter to measure the full load degree of the car. The object types may have an additive effect on the full load degree of the car, and the additive effect of a specific object type on the full load degree of the car may be configured according to actual requirements. When the number of in-car objects is located within the preset second interval, determining the priority of the door opening signal and the priority of the door closing signal according to the object types 2023396368  07 Jul 2025 of the objects in the car region and the number of elevator-waiting objects may include: determining whether the object types of the objects in the car region include the specific object type; in response to the object types of the objects in the car region including the specific object type, calculating the full load degree of the car region according to the additive effect corresponding to the specific object type and then determining the number of accommodable elevator-waiting objects according to the full load degree of the car region; if the number of accommodable elevator-waiting objects is greater than or equal to the number of elevator-waiting objects, determining that the priority of the door opening signal is higher than the priority of the door closing signal; if the number of accommodable elevator-waiting objects is smaller than the number of elevator-waiting objects, determining that the priority of the door closing signal is higher than the priority of the door opening signal.

[0064] In an optional embodiment of the present application, the object types include a target type, and determining the priority of the door opening signal and the priority of the door closing signal according to the object types of the objects in the car region and the number of elevatorwaiting objects includes the steps below.

[0065] Whether the object types of the objects in the car region include the target type is determined. An object of the target type is an object that requires a spacious environment. In response to the object types of the objects in the car region including the target type, the occupied area when the spacious environment is formed is calculated according to the object information of the objects in the car region. The priority of the door opening signal and the priority of the door closing signal are determined according to the area of the car region, the occupied area, and the number of elevator-waiting objects.

[0066] The target type is a specific type that has an additive effect on calculation of the area of an object in the car, that is, the object that requires the spacious environment, or an object that is not suitable for squeezing, such as an elderly person, an infant, a pregnant woman, a wheelchair rider, or a rigid large object. The occupied area of the car region is calculated according to the area additive effect of this specific type and is used as the occupied area when the spacious 2023396368  07 Jul 2025 environment is formed. For example, when the actual occupied area of a child is 0.2 m2, and the actual occupied area of other objects is 1 m2, to prevent the child from being squeezed, the additive effect (an addition coefficient) of "child" is set to 2, the occupied area of the child is 0.4 m2, and the calculated occupied area of the objects in the car region is 1.4 m2. The number of accommodable elevator-waiting objects is determined according to the difference between the area of the car region and the occupied area. If the number of accommodable elevator-waiting objects is greater than or equal to the number of elevator-waiting objects, the priority of the door opening signal is determined to be higher than the priority of the door closing signal. If the number of accommodable elevator-waiting objects is smaller than the number of elevator-waiting objects, the priority of the door closing signal is determined to be higher than the priority of the door opening signal.

[0067] The object information further includes projection areas of the objects and elevatorriding states of the objects, and calculating, according to the object information of the objects in the car region, the occupied area when the spacious environment is formed includes calculating the sum of the projection areas of the objects in the car region to obtain the total projection area; determining the number of objects of the target type and a weight coefficient of the target type; calculating the product of the number of objects of the target type, the weight coefficient, and the preset area of the spacious environment, and calculating the sum of the product and the total projection area to obtain the occupied area when the spacious elevator-riding environment is formed.

[0068] In an example, the total projection area of the objects in the current car region may also be determined according to the projection areas of the objects and the elevator-riding states of the objects. The elevator-riding states include entering the car and walking out of the car, that is, the projection area of each object entering or walking out of the car is accumulated, a coefficient of the projection area for the elevator-riding state being entering the car is 1, and a coefficient of the projection area for the elevator-riding state being walking out of the car is -1.

[0069] The weight coefficient is pre-configured for the target type. For example, if the target 2023396368  07 Jul 2025 type is an elderly person, the weight coefficient is 1.8, and if the target type is a child, the weight coefficient is 1.3. Weights are configured for different types according to actual requirements. The preset area of the spacious environment is the allowance area for each target type, that is, whether it is an elderly person or a child, the preset area of the spacious environment is the same, but occupied areas of objects of different target types are adjusted by weight coefficients.

[0070] Determining the priority of the door opening signal and the priority of the door closing signal according to the area of the car region, the occupied area, and the number of elevatorwaiting objects includes calculating the difference between the area of the car region and the occupied area to obtain the remaining elevator-riding area; obtaining the number of remaining elevator-riding objects according to the remaining elevator-riding area and a preset unit object area; determining whether the number of elevator-waiting objects is smaller than the number of remaining elevator-riding objects; in response to the number of elevator-waiting objects being less than or equal to the number of remaining elevator-riding objects, determining that the priority of the door opening signal is higher than the priority of the door closing signal; in response to the number of elevator-waiting objects being larger than the number of remaining elevator-riding objects, determining that the priority of the door closing signal is higher than the priority of the door opening signal.

[0071] The preset unit object area is the average area occupied by a preset object. Since each object may be different in height, weight, and size, the average area may be used for estimating the area of each object. After the remaining elevator-riding area is calculated, the ratio of the remaining elevator-riding area to the preset unit object area can be calculated to obtain the number of remaining elevator-riding objects. In the case where it has been determined that there is an object of the target type in the car, that is, the object requires the spacious environment, if there are many elevator-waiting objects, when the elevator door is opened, it is impossible to control the number of elevator-waiting objects entering the car, which may destroy the spacious environment. Therefore, in the case where it is determined that there is the object of the target type in the car, only when it is determined that the number of elevator-waiting objects in the out-of-hall region is less than or equal to the number of remaining elevator-riding objects, the priority 2023396368  07 Jul 2025 of the door opening signal is determined to be higher than the priority of the door closing signal. In this case, even if all the elevator-waiting objects enter the car, the spacious environment is not destroyed, and the spacious environment of the object of the target type can be guaranteed. When the object of the target type is a rider such as an elderly person, a child, or a pregnant woman, the elevator-riding sense of the object is enhanced, and the safety of such a rider is also guaranteed. When the object of the target type is a rigid large object, other riders can be prevented from crowding in the car and squeezing or colliding with the rigid object, thereby avoiding discomfort.

[0072] In S209, when the number of in-car objects is located within the preset third interval, the priority of the door closing signal is determined to be higher than the priority of the door opening signal.

[0073] When the number of in-car objects is located within the preset third interval, it means that the full load degree of the car is high. In this case, the priority of the door closing signal may be determined to be higher than the priority of the door opening signal to avoid excessive squeezing of riders in the car.

[0074] It is to be noted that when the interval in which the number of in-car objects is located is determined, whether the number of in-car objects is located within a certain interval may be determined in sequence. For example, whether the number of in-car objects is located within the first interval is first determined. If not, whether the number of in-car objects is located within the second interval is then determined. If not, the number of in-car objects may be determined to be located within the third interval.

[0075] In this embodiment, the priority of the door opening signal and the priority of the door closing signal are determined according to the number of in-car objects, the number of elevatorwaiting objects, and the object types of the objects in the car region. When the objects are objects that require the spacious environment, in the case where there is the object of the target type in the car, the priority of the door opening signal is determined to be higher than the priority of the door closing signal only when it is determined that the number of elevator-waiting objects in the out-of-hall region is less than or equal to the number of remaining elevator-riding objects. This 2023396368  07 Jul 2025 ensures the spacious environment in the car region, improves the elevator-riding experience of riders, improves the safety, optimizes the control logic, and makes the priority of the door opening signal and the priority of the door closing signal processed more reasonably.

[0076] Embodiment three

[0077] FIG. 3 is a flowchart of a signal priority determination method according to embodiment three of the present application. The embodiment of the present application is refined based on the preceding embodiment one. As shown in FIG. 3, the signal priority determination method includes the steps below.

[0078] In S301, the image of the detection region is collected, where the detection region includes the out-of-hall region of the elevator and the car region of the elevator.

[0079] A sensor collects the image of the detection region. The detection region is a region within the range of a viewing angle of the sensor.

[0080] In S302, the object information of the objects using the elevator in the detection region is determined according to the image.

[0081] The object information includes the number of in-car objects in the car region and the object types of the in-car objects and further includes the projection areas of the objects.

[0082] In S303, the projection areas of the objects in the car region are calculated to obtain the total projection area.

[0083] The total projection area of the objects in the current car region may be determined according to the projection areas of the objects and the elevator-riding states of the objects. The elevator-riding states include entering the car and walking out of the car, that is, the projection area of each object entering or walking out of the car is accumulated, the coefficient of the projection area for the elevator-riding state being entering the car is 1, and the coefficient of the projection area for the elevator-riding state being walking out of the car is -1.

[0084] In S304, the priority of the door opening signal and the priority of the door closing signal 2023396368  07 Jul 2025 are determined for the elevator door of the elevator according to the total projection area and the area of the car region.

[0085] In an optional embodiment of the present application, determining the priority of the door opening signal and the priority of the door closing signal for the elevator door of the elevator according to the total projection area and the area of the car region includes the steps below.

[0086] Whether the difference between the area of the car region and the total projection area is larger than the reserved area is determined. In response to the difference between the area of the car region and the total projection area being greater than or equal to the reserved area, the priority of the door opening signal is determined to be higher than the priority of the door closing signal for the elevator door of the elevator. In response to the difference between the area of the car region and the total projection area being smaller than the reserved area, the priority of the door closing signal is determined to be higher than the priority of the door opening signal.

[0087] Since the fatness degrees of elevator-riding objects are not uniform, it may be inappropriate to determine, by counting the elevator-riding objects, whether the current car is fully loaded. For example, the full load degree of the car when there are multiple riders with a large body circumference is actually larger than the full load degree of the car when there are riders with a small body circumference. Therefore, if whether the current car is fully loaded is determined only by counting the elevator-riding objects, the elevator-riding experience of the incar objects or the elevator-waiting objects may be affected. Therefore, in the present application, the full load degree of the current car is determined by the projection areas of the objects, that is, whether the difference between the area of the car region and the total projection area is larger than the reserved area is determined, where the reserved area may be the average projection area of an object. That is, though the total projection area is smaller than the area of the car region, the difference between the area of the car region and the total projection area still has to be able to accommodate at least one object in order to allow a newly added elevator-waiting object to be admitted.

[0088] In another optional embodiment of the present application, determining the priority of 2023396368  07 Jul 2025 the door opening signal and the priority of the door closing signal for the elevator door of the elevator according to the total projection area and the area of the car region further includes the steps below.

[0089] Whether the difference between the area of the car region and the total projection area is larger than the reserved area is determined. In response to the difference between the area of the car region and the total projection area being greater than or equal to the reserved area, the priority of the door opening signal is determined to be higher than the priority of the door closing signal for the elevator door of the elevator. In response to the difference between the area of the car region and the total projection area being smaller than the reserved area, the area of a vacant region in the car region that communicates with the elevator door is detected according to the image. Whether the area of the vacant region is larger than the reserved area is determined. In response to the area of the vacant region being greater than or equal to the reserved area, the priority of the door opening signal is determined to be higher than the priority of the door closing signal. In response to the area of the vacant region being smaller than the reserved area, the priority of the door closing signal is determined to be higher than the priority of the door opening signal.

[0090] This embodiment is refined based on the preceding embodiment. In this embodiment, the projection area of each object may be considered as the maximum occupied area of each object, but generally speaking, the actual occupied area of each object (such as each rider) may be smaller than the projection area of each object, that is, through an adjustment on the position, the shape, or the distance from each object to an object adjacent to each object, each object may have the actual occupied area smaller than the projection area. For example, the clothes worn by each rider are fluffy, resulting in a large projection area, but each rider actually occupies a small area. For another example, when multiple riders stand side by side, the total occupied area of the multiple riders is smaller than the total projection area of the multiple riders, that is, "making room". Therefore, when the difference between the area of the car region and the total projection area is smaller than the reserved area, the area of the vacant region in the car region that communicates with the elevator door may also be detected, that is, to confirm whether the in-car objects "make 2023396368  07 Jul 2025 room" for the vacant region. In response to the in-car objects "making room" for the vacant region, whether the vacant region that has "made room" is larger than the reserved area is determined, where the reserved area may be the average projection area of an object. That is, though the total projection area is smaller than the area of the car region, the difference between the area of the car region and the total projection area still has to be able to accommodate at least one object in order to allow a newly added elevator-waiting object to be admitted. In this embodiment, the priority of the door opening signal and the priority of the door closing signal are determined by combining the projection areas and the area of the vacant region in the car region that communicates with the elevator door so that the priority of the door opening signal and the priority of the door closing signal can be processed more in line with an actual elevator-riding scenario, the control logic can be optimized, the case where there is still a large vacant region when the full load degree of the elevator is determined according to the total projection area can be avoided, and the usage efficiency of the elevator can also be improved.
