[0002] Over the long-term service life of elevator equipment, the need for optimized operational efficiency and functional upgrades gradually emerges as components age, technical standards evolve, and user demands evolve. The current industry-wide modification decision-making mechanism is significantly reliant on experience: end users typically obtain modification plans through sales engineers and technical support personnel, a process that lacks a systematic, intelligent decision-making support system.

[0003] Therefore, there is a need for a system that can automatically recommend elevators based on current elevator information and user needs. Summary of the Invention

[0004] The present disclosure proposes an intelligent elevator recommendation method and corresponding device, which can automatically recommend elevators based on current elevator information and user needs.

[0029] Existing elevator renovation recommendations rely solely on the fragmented experience and knowledge of individual practitioners, without a comprehensive data-based intelligent analysis model. This results in a lack of objective, quantitative evidence for these recommendations. This experience-based model struggles to effectively adapt to diverse user scenarios and meet the demands for intelligent, personalized, and responsive elevator system renovations within the context of smart city development. The purpose of this disclosure is to build an intelligent elevator recommendation system based on data analysis.

[0030] Figure 1 A method for generating elevator recommendations according to an embodiment of the present disclosure is shown.

[0031] In step S110, current elevator information and first personalized information are acquired.

[0032] In one embodiment, both the current elevator information and the first personalized information can be obtained from the user, for example, through user input. Furthermore, the current elevator information and the first personalized information can also be obtained from the internet. For example, the current elevator information can be obtained from the user's elevator purchase order information, while the first personalized information can be obtained from the user's inquiry history. Furthermore, when the user enters information, options can be provided to facilitate selective input. For example, the first personalized information can include common personalized requirements for the user to select. In addition to providing an input box for the elevator brand and model, the current elevator information can also prompt the user to enter external information about the elevator site and other information that facilitates elevator recommendations. For example, the user's city, the purpose of the building where the elevator is located, the number of elevator floors, the elevator type (e.g., with or without a machine room), the rated load, the rated speed, the number of floors, the number of stations, the lift height, the control method, and so on. Such prompts can quickly gather the necessary information for making accurate elevator recommendations and facilitate the user to specifically organize current elevator information, examine potential problems with the existing elevator, and identify potential elevator optimization options.

[0033] In an embodiment, the first personalized information may be related to the user's desired direction for elevator improvement. For example, the first personalized information may include at least one of increasing elevator speed, enlarging the elevator car, saving energy, increasing load capacity, upgrading intelligence, and improving safety. In an alternative embodiment, the first personalized information may be related to a current elevator problem input by the user. For example, such problems may include elevator jitter, elevator congestion, low elevator efficiency, etc.

[0034] In step S120 , a first recommendation is generated based on the current elevator information and the first personalized information, where the first recommendation includes at least two elevator update solutions.

[0035] In a further embodiment, the at least two elevator update plans include at least one of an elevator overall update plan and an elevator component update plan.

[0036] For example, the first personalized information for increasing the elevator speed combined with the current elevator information can generate a first recommendation including four recommended solutions: 1. Replace safety components; 2. Replace the elevator host and safety components; 3. Replace the host, electrical system and safety components; and 4. Replace the entire elevator.

[0037] For another example, in response to the current problem of crowded elevator cars and combined with current elevator information, a first recommendation can be generated that includes three recommended solutions: 1. Replace the car and safety components; 2. Replace the car, elevator motor, electrical system and safety components; and 3. Replace the entire elevator.

[0038] More specifically, in the above-mentioned recommendation schemes, a specific elevator component model or a specific elevator model may be given in each recommendation scheme.

[0039] In one embodiment, the first recommendation may be displayed in the form of a list of at least two elevator upgrade options. In a further embodiment, when at least one of the at least two elevator upgrade options in the list is selected, a 3D elevator model corresponding to the selected elevator upgrade option is displayed such that the recommended replacement component is highlighted, thereby providing a more intuitive presentation to the customer.

[0040] In another embodiment, the first recommendation may be displayed as a matrix table comparing key elevator installation factors of at least two elevator update solutions. In a further embodiment, when at least one of the at least two elevator update solutions in the matrix table is selected, a 3D elevator model corresponding to the selected elevator update solution is displayed.

[0041] In another embodiment, the first recommendation may be displayed in the form of a 3D elevator model that highlights the at least two elevator update solutions in a differentiated manner. For example, components recommended for update in the first elevator update solution may be highlighted in red, while components recommended for update in the second elevator update solution may be highlighted in green.

[0042] In step S130, the user's selection of the elevator update solution in the first recommendation and second personalized information may be obtained, where the second personalized information includes configuration information related to a different category or more detailed configuration information than the first personalized information.

[0043] Regarding different categories, the first personalized information might relate to a user goal of increasing elevator speed, while the second personalized information might be related to elevator size or elevator load—that is, configurations related to different categories of elevator speed. For another example, the second personalized information might include one or more of the distance from the original sill to the door frame, the traction ratio, the display panel type, and other technical configuration parameters. Regarding more detailed configuration information, for example, the first personalized information might relate to a user goal of increasing elevator speed, while the second personalized information might include a specific rated speed value. If the first personalized information relates to a current issue of underload, the second personalized information might include a specific rated load value. In yet another example, the first personalized information might relate to core operating parameters or basic performance parameters of the elevator, while the second personalized information might relate to system characteristic parameters or technical configuration parameters of the elevator. In other words, the second personalized information can complement and improve the first personalized information, or it can be a more specific and precise version of the first personalized information.

[0044] In step S140, after receiving the user's selection of at least one elevator updating solution in the first recommendation, a final elevator updating solution may be generated based on the elevator updating solution selected by the user and the second personalized information.

[0045] In one example, the quotation information corresponding to the final elevator update plan can be displayed together with the plan. By obtaining the second personalized information different from the first personalized information, each configuration in the elevator update plan can be confirmed so that specific quotation information can be given to the user.

[0046] In another example, various parameter information corresponding to the final elevator updating plan, especially parameter information related to the first personalized information and the second personalized information, may be displayed together with the final elevator updating plan.

[0047] Figure 2 A method 200 for generating a first recommended elevator component update solution according to an embodiment of the present disclosure is shown.

[0048] Considering that this is a partial update or replacement of an existing elevator, the degree to which the goal corresponding to the first personalized information can be achieved is limited by conditions external to the current elevator site, such as spatial conditions. Therefore, in step S210, a first achievable limit value corresponding to the first personalized information can be determined based on the external elevator site information included in the current elevator information.

[0049] The elevator on-site external information may include, but is not limited to, the pit depth, top floor height, and shaft dimensions of the existing shaft. For example, based on the elevator on-site external information included in the current elevator information, it is determined that the maximum speed limit in the current elevator space is 3 m / s.

[0050] In step S220, a current core elevator component that restricts the realization of the first personalized information among the current elevator components may be determined based on the current elevator component information included in the current elevator information.

[0051] The current core elevator components mentioned here can be all components in the current elevator components that restrict the realization of the first personalized information. In other words, the current core elevator components that restrict the realization of the first personalized information can be one component or more than one component.

[0052] For example, assuming that the first personalized information is to increase the elevator speed, the components that limit the speed increase may include the safety component and the elevator main unit. In this case, the current core elevator components include the safety component and the elevator main unit (including the traction machine).

[0053] In step S230 , a replacement core elevator component that replaces the current core elevator component may be determined from the candidate core elevator components based on the first achievable limit value.

[0054] For example, a replacement safety component that supports an elevator speed of less than 3 m / s may be determined from candidate safety components based on the achievable limit value of the elevator speed of 3 m / s.

[0055] Here, all candidate components or the candidate elevators mentioned later may be stored in a memory or acquired and selected via at least one of an internet search, AI tools, or big data processing technology. The memory may be a local memory or a remote memory outside of the elevator recommendation device, such as a cloud storage.

[0056] In a further embodiment, the candidate safety components or the candidate elevators mentioned later may be limited by brand or other specific parameters (such as price), thereby narrowing the range of candidate components or elevators and further improving the efficiency of generating recommendations.

[0057] When the current core elevator components include two or more components, replacement core elevator components are selected from the candidate corresponding component library to replace each of these components. For example, when the current core elevator components include a safety component and an elevator main unit, a replacement safety component and a replacement elevator main unit can be selected from the candidate safety components and all candidate elevator main units based on the determined elevator speed limit, such that the supported elevator speed is less than the achievable speed limit but greater than the current elevator motion speed.

[0058] For each core elevator component replacement, a single recommended solution can be provided (e.g., a recommended solution that meets the first personalized information requirement but has the lowest cost). Alternatively, two or more recommendations can be provided (e.g., multiple recommended solutions that meet the first personalized information requirement to varying degrees and have different costs). In another embodiment, the number of recommended solutions can be determined based on user needs and settings.

[0059] In a further embodiment, a recommended achievable value corresponding to the first personalized information may be first determined based on the first achievable limit value and information about the current core elevator component, and then a replacement core elevator component for replacement may be determined from candidate core elevator components based on the recommended achievable value corresponding to the first personalized information.

[0060] For example, a recommended elevator operating speed of 2 m / s may be determined based on an elevator limit value of 3 m / s and the current elevator movement speed. Based on the recommended elevator operating speed (elevator speed of 2 m / s), a replacement safety component that can support the recommended elevator operating speed is determined from candidate safety components.

[0061] In step S240, an elevator component updating solution for updating by replacing core elevator components may be generated as an elevator updating solution in the first recommendation.

[0062] Specifically, the replacement core elevator component that meets the requirements selected from the candidate components in step S230 can be displayed as the elevator component to be updated in the elevator update solution. For example, continuing with the above example, the model of the selected specific safety component or the model of the elevator host can be displayed.

[0063] In the above method according to this embodiment, the elevator on-site external information included in the current elevator information is taken into consideration to update the elevator components, so that there will be no scenario where the recommended elevator components are not applicable, and a component update solution that maximizes the realization of the user's personalized needs can be found without replacing the entire elevator.

[0064] In other embodiments, instead of replacing all components that restrict the implementation of the first personalized information, the number of core elevator components that restrict the implementation of the first personalized information can be determined based on the user's budget or needs. For example, if the user's budget is low, only one core elevator component that has the highest program constraint on the implementation of the first personalized information can be determined. By setting the number of components to be replaced based on the user's budget or needs, a component upgrade solution that addresses only the current elevator's greatest bottleneck can be more conveniently and personalized.

[0065] If the user has a low budget and therefore decides to update only the minimum number of core elevator components (for example, only one elevator component), then information about other elevator components in addition to the elevator site external information can be considered to further narrow down the options for core elevator components and further reduce the component update cost. Figure 3 A method 300 for generating a first recommended elevator update solution according to another embodiment of the present disclosure is shown.

[0066] First, in step S310, based on the current elevator component information included in the current elevator information, the core elevator components that most restrict the realization of a predetermined number of the first personalized information can be determined. For example, by checking and comparing the current elevator components one by one, it may be discovered that the safety component that most restricts the elevator's operating speed (in this example, the elevator's operating speed is the target of the first personalized information) may be found.

[0067] It's important to note that the "predetermined number of current core elevator components that most restrict the implementation of the first personalized information" here refers to the top N current core elevator components ranked from highest to lowest in terms of their degree of restriction on the implementation of the first personalized information (N corresponds to the predetermined number, where N is a positive integer greater than or equal to 1). This allows for more flexible determination of the number of components to be replaced and more precise control of user budgets. For example, the two core elevator components that most restrict the implementation of the first personalized information may include the core elevator component with the highest degree of restriction and the other core elevator component with the second highest degree of restriction.

[0068] Then, in step S320, a second achievable limit value corresponding to the first personalized information can be determined based on the elevator site external information included in the current elevator information and information related to elevator components other than the current core elevator component. Compared to the achievable limit value determined based solely on the elevator site external information in step S220, S320 further considers information related to elevator components other than the determined current core elevator component. This avoids situations where other elevator components do not support the performance of the replaced core elevator component and narrows the range of recommended core components, thereby providing more accurate and potentially lower-cost recommendations.

[0069] For example, based on the elevator on-site external information included in the current elevator information, it is determined that the maximum speed limit in the current elevator space is 3 m / s, and the maximum speed limit supported by elevator components other than the determined current core elevator component(s) is 1.8 m / s. Therefore, the second achievable limit is 1.8 m / s. Therefore, the replaced core elevator component cannot operate at a speed higher than 1.8 m / s, otherwise safety hazards or other problems may occur.

[0070] Next, in step S330, a replacement core elevator component is determined from candidate core elevator components based on the second achievable limit value to replace the current core elevator component. Specifically, if the current core elevator component is a safety component, only safety components with a rated speed less than 1.8 m / s may be considered when selecting from the candidate safety component library.

[0071] Finally, in step S340, an elevator component updating solution for updating by replacing core elevator components may be generated as an elevator updating solution in the first recommendation.

[0072] When generating an overall elevator update plan, there is no need to consider the components used in the current elevator itself. However, in addition to the goals to be achieved corresponding to the first personalized information, the recommended elevators also need to be restricted by external information on the elevator site (such as spatial conditions). Figure 4 A method 400 for generating a first recommended overall elevator update solution according to an embodiment of the present disclosure is shown.

[0073] In step S410, a third achievable limit value corresponding to the first personalized information and other key elevator installation requirements unrelated to the first personalized information may be determined based on the elevator site external information included in the current elevator information.

[0074] Other key elevator installation requirements herein may involve installation factors other than aesthetic factors.

[0075] For example, if the first personalized information is to increase the elevator speed, and based on the elevator on-site external information included in the current elevator information, it is determined that the updated maximum achievable speed of the elevator is 3 m / s, and based on the elevator on-site external information included in the current elevator information, other key elevator installation requirements that are not directly related to the elevator operating speed can also be determined, such as the current elevator's purpose, floor height, or the values or value ranges of some other system parameters.

[0076] In step S420, at least one elevator overall update solution may be determined from the candidate elevator overall update solutions as the first recommended elevator update solution based on the third achievable limit value and other key elevator installation requirements.

[0077] For example, based on the maximum achievable speed of 3 m / s and key elevator installation requirements such as the current elevator's purpose and floor height, an elevator that meets the speed requirements and other key elevator installation requirements can be determined from the candidate elevator overall update plans as the elevator update plan.
