[0068] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Description of the Drawings

[0069] The accompanying drawings are used to provide a further understanding of the present invention, and constitute a part of the specification. Together with the embodiments of the present invention, they are used to explain the present invention, but do not constitute a limitation to the present invention. In the accompanying drawings:

[0070] Figure 1 It is a schematic diagram of a method for constructing an elevator digital twin model in an embodiment of the present invention;

[0071] Figure 2 It is a schematic diagram of a system for constructing an elevator digital twin model in an embodiment of the present invention. Detailed Embodiments

[0072] The following describes the preferred embodiments of the present invention with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0073] The embodiment of the present invention provides a method for constructing an elevator digital twin model, as Figure 1 shown, including:

[0074] S1. Based on the first digital twin template, construct a digital twin model of the elevator in the building;

[0075] S2. Obtain at least one supplementary construction requirement of the digital twin model;

[0076] S3. Based on each of the supplementary construction requirements, determine a second digital twin template;

[0077] S4. Based on the second digital twin template, perform supplementary construction on the digital twin model.

[0078] The first digital twin template is a template indicating how to integrate the basic information related to the elevator into the digital twin model. For example, integrating basic information such as the location and size of the elevator into the digital twin model; based on the first digital twin template, initially constructing the digital twin model of the elevator; the supplementary construction requirement is the requirement for supplementary construction of the digital twin model triggered during the operation of the elevator. For example, when a passenger enters the elevator, the supplementary construction requirement is to display the destination floor and the number of passengers of the elevator carrying passengers. Another example is that when the elevator is about to enter the shutdown maintenance time, the supplementary construction requirement is to display the prompt information that the elevator is about to enter the shutdown maintenance time and the list of maintenance responsible personnel of the elevator; the second digital twin template is a template indicating how to supplement and construct the digital twin model based on the supplementary construction requirement. For example, if the supplementary construction requirement is to display the destination floor and the number of passengers of the elevator carrying passengers, the second digital twin template is to integrate the destination floor and the number of passengers information of the elevator carrying passengers into the digital twin model; based on the second digital twin template, supplement and construct the digital twin model.

[0079] This application first initially constructs a digital twin model integrating the basic information related to the elevator. When the digital twin model generates a supplementary construction requirement, it then supplements and constructs the digital twin model based on the supplementary construction requirement, without directly integrating all the relevant information of the elevator into the digital twin model, reducing the resource occupation and operating power consumption of the digital twin model, improving the applicability to device terminals for viewing the digital twin model with different configurations, and reducing device costs.

[0080] In one embodiment, obtaining at least one supplementary construction requirement of the digital twin model includes:

[0081] When the user views the digital twin model from at least one first perspective within a preset first time period, and the first viewing duration of the user viewing the digital twin model from each of the first perspectives is greater than or equal to a preset first duration threshold, obtain at least one first digital twin body that appears simultaneously under each of the first perspectives in the digital twin model;

[0082] When the user views the digital twin model from a number of second perspectives greater than or equal to a preset number within a preset second time period, and the second viewing duration of the user viewing the digital twin model from each of the second perspectives is less than or equal to a preset second duration threshold, and at least one of the first digital twin bodies appears under each of the second perspectives in the digital twin model, obtain the position change sequence of the same first digital twin body under different second perspectives;

[0083] When the similarity between the position change sequence and any preset standard position change sequence is greater than or equal to a preset similarity threshold, determine at least one supplementary construction history corresponding to each of the second perspectives from the preset supplementary construction history libraries corresponding to each of the first digital twins;

[0084] Based on each of the supplementary construction histories, determine at least one of the supplementary construction requirements;

[0085] Wherein, the second time period is after the first time period.

[0086] The first time period is the time period between the moment when the user starts to view the digital twin model and the moment 100 seconds later; the second time period is the time period between 10 seconds and 100 seconds after the first time period; the first time period and the second time period can be set in advance by technicians according to actual needs; the first duration threshold can be 15 seconds; the digital twin model is a three-dimensional model, and a viewing perspective will be generated when the user views the digital twin model; when the user views the digital twin model from at least one first perspective within the first time period and the first viewing duration of viewing the digital twin model from each first perspective is greater than or equal to the first duration threshold, it indicates that the user is focusing on viewing the digital twin model to monitor and manage the elevator, and obtain the first digital twin entities that appear simultaneously under each first perspective. The first digital twin entities are the objects that the user may want to monitor and manage when focusing on viewing. The digital twin entity is the representation object in the digital twin model after the digital twin of the real elements of the elevator; the preset number can be 2; the second duration threshold can be 3 seconds; when the user views the digital twin model from a number of second perspectives greater than or equal to the preset number within the second time period, and the second viewing duration of viewing the digital twin model from each second perspective is less than or equal to the second duration threshold and at least one second digital twin entity appears under each second perspective, it indicates that the user is dragging the digital twin model to switch the perspective and may be looking for information to view near the first digital twin entity, and obtain the position change sequence of the same first digital twin entity that appears under different second perspectives; the standard position change sequence is the position change sequence of the same first digital twin entity that reflects that the user is indeed looking for information to view near the first digital twin entity. For example, if the same first digital twin entity appears in the lower left position and the upper left position of the second perspective in sequence, it indicates that the user is looking for information to view from top to bottom on the right side of the first digital twin entity; therefore, when the similarity between the position change sequence and any preset standard position change sequence is greater than or equal to the preset similarity threshold, it is determined that the user is looking for information to view near the first digital twin entity. At this time, a supplementary construction requirement is generated, and it is necessary to determine the supplementary construction requirement; the similarity threshold can be 70%; the first digital twin entity is preset with a supplementary construction history library, and there is a supplementary construction history corresponding to different second perspectives in the supplementary construction history library. The supplementary construction history is the history of supplementing content related to the first digital twin entity under the second perspective in the past; based on the supplementary construction history, the supplementary construction requirement can be determined.

[0087] In the embodiment of the present invention, when obtaining the supplementary construction requirement, it accurately identifies whether the user is looking for information that is not in the digital twin model but the user wants to view, and determines the supplementary construction requirement, which greatly improves the applicability of obtaining the supplementary construction requirement.

[0088] In one embodiment, obtaining at least one supplementary construction requirement for the digital twin model includes:

[0089] When the user continuously views at least two monitoring images in the video monitoring platform of the building within a preset third time period, at least one building abnormal event in each of the monitoring images is identified;

[0090] When the user views the digital twin model at least once within a preset fourth time period, at least one development trend of each of the building abnormal events is predicted;

[0091] At least one elevator emergency plan corresponding to each of the development trends is determined from a preset elevator emergency plan library corresponding to the building;

[0092] Based on each of the elevator emergency plans, at least one of the supplementary construction requirements is determined;

[0093] Wherein, the fourth time period is after the third time period.

[0094] The video monitoring platform is a platform built in the building for video monitoring of multiple locations in the building, and the function of viewing monitoring images is provided in the video monitoring platform; the third time period is the time period between the moment when the user starts to view the video monitoring platform and the moment 50 seconds later; when the user continuously views at least two monitoring images within the third time period, it indicates that an abnormal event in the building may have occurred, and at least one building abnormal event in each monitoring image is identified; the fourth time period is the time period between 5 seconds and 20 seconds after the third time period; when the user views the digital twin model at least once within the fourth time period, it indicates that the user wants to use the digital twin model to assist in dealing with the building abnormal event and predict the development trend of the building abnormal event; there are elevator emergency plans corresponding to different development trends in the elevator emergency plan library; specifically, for example: the building abnormal event is that a certain household is chased by illegal personnel, the development trend is the future movement trajectory predicted based on the historical movement trajectories of the household and the illegal personnel, and the elevator emergency plan is to control the elevator corresponding to the elevator landing door pointed to by the future movement trajectory to go to the corresponding floor, the landing door is opened in advance after the elevator arrives, and after waiting for the chased household to enter, the elevator landing door is closed; therefore, based on the elevator emergency plan, supplementary construction requirements can be determined, such as: supplementing and constructing the current position information of the elevator corresponding to the elevator landing door pointed to by the future movement trajectory, all monitoring image information of the floor where the future movement trajectory is generated, etc.

[0095] When obtaining the supplementary construction requirements in the embodiments of the present invention, it is identified whether the user wants the digital twin model to be linked with the video monitoring platform. When it is identified that linkage is required, the supplementary construction requirements are adaptively determined according to the elevator emergency plan, which greatly improves the applicability of the system.

[0096] In one embodiment, determining the second digital twin template based on each of the supplementary construction requirements includes:

[0097] Determine at least one digital twin rule corresponding to each of the supplementary construction requirements from a preset digital twin rule library;

[0098] Determine the second digital twin template based on each of the digital twin rules.

[0099] There are digital twin rules corresponding to different supplementary construction requirements in the digital twin rule library. For example, if the supplementary construction requirement is to supplement the list of maintenance responsible personnel for the elevator, the corresponding digital twin rule is to retrieve the list information of the maintenance responsible personnel corresponding to the elevator to be maintained from the maintenance responsible personnel list library and set this information beside the corresponding elevator in the digital twin model; therefore, the second digital twin template can be determined based on each digital twin rule.

[0100] In one embodiment, the method for constructing an elevator digital twin model further includes:

[0101] Determine at least one element to be concerned about based on the supplementary construction requirements;

[0102] Determine at least one second digital twin body corresponding to each of the elements to be concerned about from the digitally twin model after supplementary construction;

[0103] Control a preset virtual camera to enter the digitally twin model after supplementary construction;

[0104] Based on the tracking shooting requirements, control the virtual camera to track and shoot each of the second digital twin bodies to obtain shooting images;

[0105] Suspend and display the shooting images in the digitally twin model after supplementary construction;

[0106] Among them, the tracking shooting requirements include:

[0107] Each of the second digital twin bodies completely falls within the shooting range of the virtual camera;

[0108] The third digital twin body corresponding to the target element in the digitally twin model after supplementary construction falls within the shooting range of the virtual camera; the target element includes: the trigger element corresponding to the behavioral relationship between any two of the second digital twin bodies in a preset trigger element library;

[0109] The vector angle between the shooting perspective vector of the virtual camera and the change trend vector of each of the second digital twin bodies falls within a preset angle interval.

[0110] The elements to be concerned about are the elements that need to be concerned about in the digital twin model after supplementary construction to supplement the construction of demand response. For example, if the supplementary construction demand is to obtain all the monitoring screen information of the floors where the residents being chased by illegal personnel and the future movement trajectories of the illegal personnel are located, then the elements to be concerned about are the residents, illegal personnel, elevators on the floors where they are located, etc.; after supplementing and constructing the digital twin model based on the supplementary construction demand, there will be a second digital twin body corresponding to each element to be concerned about in the digital twin model; control the virtual camera to track and shoot the second digital twin body, and floatingly display the shooting screen to assist the user in quickly tracking and understanding the situation of the elements to be concerned about, without the need to drag the digital twin model by themselves to adjust the viewing angle, improving the convenience; in the tracking shooting requirement, each second digital twin body needs to completely fall within the shooting range of the virtual camera to ensure that each second digital twin body is completely displayed in the shooting screen; there are trigger elements corresponding to different behavioral relationships in the trigger element library. For example, if the behavioral relationship is the confrontation between the resident and the illegal personnel, the trigger element is the security personnel who go to the scene to stop; make the third digital twin body corresponding to the trigger element also fall completely within the shooting range of the virtual camera, so that the user can completely understand the situation; the shooting perspective vector is a direction vector constructed based on the position and shooting direction of the virtual camera, and the change trend vector is a direction vector constructed based on the current position and the last movement direction of the second digital twin body. The included angle interval can be from 120 degrees to 180 degrees, which can make the virtual camera shoot at an angle as close as possible to the front of the second digital twin body, facilitating the capture of key situation information.

[0111] An embodiment of the present invention provides a construction system for an elevator digital twin model, as Figure 2 shown, including:
