TECHNICAL FIELD
[0001] The application relates to the technical field of elevator cost metering, and in particular to an electric energy metering cloud platform for electricity cost sharing of a lifting device. BACKGROUND
[0002] The old community elevator electricity cost sharing system is a management mechanism designed for reasonably sharing the electricity cost of the elevator after the elevator is installed in the old community. The core purpose is to improve the convenience of residents' life while realizing fair, just and transparent electricity cost sharing. The system usually combines the property management platform and the smart meter data, calculates the electricity cost proportion that each household should bear according to the use frequency of each floor household, the elevator operation period, the floor height and the number of households and other factors, and pushes the bill and settles the cost through the online payment platform or the property management system. Some systems also support residents to customize the sharing rules, such as floor ladder sharing or household sharing, to meet the actual situation and residents' needs of different communities. Through the system, not only can the neighborhood disputes caused by electricity cost sharing be effectively reduced, but also the intelligent level of community management can be improved, providing strong support for the sustainable transformation of old communities.
[0003] However, the existing technology has the problem of insufficient data integration capability in the electricity cost sharing system. Multi-source data often deviates from the calculation due to non-uniform format, time dimension misplacement or improper handling of missing values. The parameter configuration mechanism is rigid and difficult to quickly adjust the sharing rules according to different scenarios, often requiring re-development of algorithms with high adaptation cost.

[0018] In a preferred embodiment, the parameter configuration management submodule is internally provided with a parameter type classification unit, a visualization configuration unit, a template library management unit and a parameter storage unit. The parameter type classification unit divides the parameters involved in the algorithm into three categories: basic parameters, weight parameters and threshold parameters. The basic parameters include time-of-use electricity price (such as 1.2 yuan / degree during peak hours and 0.5 yuan / degree during off-peak hours), time period division (such as the default peak hours of 8:00-22:00) and other fixed values that are strongly related to external environment; the weight parameters include time period coefficients, load coefficients and other adjustment values that affect the allocation ratio; the threshold parameters include abnormal electricity fluctuation thresholds, minimum effective elevator ride number of users and other risk control values.

[0019] In a preferred embodiment, the multi-factor calculation engine submodule realizes dynamic electricity cost allocation by integrating time-of-use electricity price, elevator ride time period and elevator load rate. The calculation process takes the total elevator electricity cost of a certain community in a certain month as input. First, the total electricity is divided into peak / off-peak periods and the electricity cost of each period is calculated; second, for each user, the user contribution value is calculated by weighting the time period coefficient and the load coefficient based on the number of elevator rides during peak / off-peak periods and the elevator load state (such as empty load or full load) during the rides; finally, the total electricity cost is allocated to each user in proportion to the proportion of all user contribution values. For example, the total electricity consumption of a certain community in July is 300 degrees, including 200 degrees during peak hours (8:00-22:00) and 100 degrees during off-peak hours (22:00-8:00). The local peak electricity price is 1.2 yuan / degree and the off-peak electricity price is 0.5 yuan / degree. User A rides the elevator 10 times during peak hours and 5 times during off-peak hours, with 3 full load rides (load coefficient 1.2) and the rest half load rides (load coefficient 1.0). User B rides the elevator 8 times during peak hours and 7 times during off-peak hours, with no full load ride record. The engine will complete the segmented calculation and final allocation based on these data
[0020] Let the total electricity cost be C total , the peak period electricity cost be C high , and the off-peak period electricity cost be C low :
[0021] C total =C high +C low ;
[0022] wherein C high =Ehigh × P high (E high peak time electricity E high × P low ), low C low = E low off-peak time electricity E low × P i ).
[0023] The contribution value Vi of user i is calculated by weighting the period coefficient and the load coefficient:
[0024] V high,i = n high × α low,i + n low × α full,i + n full × β high,i
[0025] In the formula, n high is the number of times of taking the elevator in the peak time of user i, α low,i is the peak time coefficient; n low is the number of times of taking the elevator in the off-peak time, α full,i is the off-peak time coefficient; n full is the number of times of taking the elevator when the elevator is full of load, and β i=1 is the full load coefficient.
[0026] The total contribution value Vtotal of all users is ∑ N Vi, N is the total number of users.
[0027] The electricity bill Ci that user i should share is:
[0028] ;
[0029] V total represents the sum of the contribution values of all users;
[0030] C i represents the electricity bill (yuan) that user i should share.
[0031] In a preferred embodiment, the result output verification submodule is internally provided with a numerical verification unit, a rationality verification unit, a detail generation unit, and an abnormality backtracking unit. The numerical verification unit ensures that the error is controlled within 0.1 yuan by calculating the difference between the sum of the electricity bills of all users and the total electricity bill; the rationality verification unit compares the electricity bill of a user this month with the historical data of the same period, and if the number of times a user takes the elevator increases by 50% but the electricity bill increases by only 10%, the abnormality is marked and manual review is triggered; the detail generation unit generates a user electricity bill allocation report based on the calculation process, including details such as elevator time period distribution, load participation times, coefficient weighting process, etc.; the abnormality backtracking unit records the full-process data of the algorithm calculation, and when the allocation result is complained by the user, the problem link can be quickly located.
[0032] In a preferred embodiment, the user interaction and service module is internally provided with a user end application, a management end background, a data display component, and an operation function component. The user end application takes APP or applet as the carrier, provides elevator ride times query, electricity bill detail viewing, including time period and load coefficient explanation, historical payment record tracing function, supports online recharge through WeChat and Alipay, electronic invoice download, and abnormal bill complaint; the management end background is developed based on Web, includes data dashboards such as community total electricity, unit electricity consumption ranking, and non-payment user proportion, supports time period division adjustment, such as holiday peak extension, load coefficient modification, such as increasing the full load coefficient of old elevators, and other strategy configurations, as well as remote recovery of user rights, batch export of electricity bill reports, such as Excel or PDF format, and other operations; the data display component visualizes user electricity consumption trends through line charts and bar charts, and the operation function component integrates message push interfaces to realize real-time notifications such as payment reminders and elevator ride abnormality prompts.
[0033] In a preferred embodiment, the intelligent control and early warning module is internally provided with a permission control submodule, an abnormality early warning submodule, and a predictive maintenance submodule. The permission control submodule is linked with the elevator recognition terminal to automatically disable the elevator ride permission of a user who has not paid for two consecutive times, such as no response when swiping the card, and please pay first when swiping the face, and the permission is restored in real time after payment; the abnormality early warning submodule sends electricity consumption abnormality and equipment failure warnings to the maintenance personnel by analyzing the electricity data, such as a sudden increase of more than 30% in daily electricity consumption, and the elevator state data, such as a vibration frequency of more than 5Hz and a duration of 10 seconds; the predictive maintenance submodule automatically generates a maintenance plan based on the historical operation data of the elevator, such as 100,000 times of door machine switching, and synchronizes it to the to-do list of the management end background, such as replacing the door machine bearing.
[0034] In summary, the present application includes at least one of the following beneficial technical effects:
[0035] 1. Through the cooperation of the dynamic intelligent allocation algorithm module and each functional module, the accuracy of electricity allocation is significantly improved. The data input integration sub-module standardizes and aligns the time dimension of multi-source data, such as unifying the card swiping ID and facial feature code into a unique user identifier, and aligning scattered power and elevator records by day / week / month cycles to avoid calculation deviations caused by data format confusion or time misalignment; the integrity checking unit fills in missing data through a supplementary recording mechanism to ensure the completeness and reliability of the basic data for algorithm invocation. These steps collectively ensure that the input data received by the multi-factor calculation engine is true and consistent, and the allocation result can more accurately reflect the user's actual electricity consumption behavior.
[0036] 2. The parameter configuration management sub-module subdivides the parameters involved in the algorithm into basic parameters (such as time-of-use electricity price), weight parameters (such as time period coefficient), and threshold parameters (such as abnormal fluctuation threshold), and supports administrators to intuitively adjust through a visual interface. For different elevator rules of residential and commercial office buildings, the "residential template" or "commercial office building template" in the template library can be called to quickly configure parameters without the need to redevelop algorithms; after template modification, it can be directly saved and reused, reducing the system adaptation cost in different scenarios, and enabling the allocation rules to be dynamically optimized according to user needs or external environment (such as electricity price adjustment).
[0037] 3. The result output verification sub-module ensures the credibility of the allocation result through a multi-dimensional verification mechanism: the numerical verification unit strictly controls the error of the sum of the total electricity fee and user allocation (allowing small deviations due to rounding), avoiding errors and omissions due to calculation flaws; the reasonableness verification unit compares historical allocation data of users, and if there is an abnormal situation of increased elevator trips but abnormal fee growth, it will trigger manual review to prevent result distortion due to data anomalies or parameter misconfiguration; the detail generation unit provides allocation reports containing key information such as elevator time period and load coefficient (e.g. "User A contributes 42% due to 10 peak elevator trips with weighted coefficient"), allowing users to clearly trace the cost composition; the abnormal backtracking unit records the data throughout the calculation process, allowing administrators to quickly locate problem areas (such as data input errors or improper parameter configuration) when users have doubts about the results, timely resolving disputes and enhancing user trust in the system.

[0056] The internal setting of the parameter configuration management submodule 8 is provided with a parameter type classification unit, a visual configuration unit, a template library management unit and a parameter storage unit. The parameter type classification unit divides the parameters involved in the algorithm into three categories of basic parameters, weight parameters and threshold parameters. The basic parameters include time-of-use electricity price (such as peak 1.2 yuan / degree, valley 0.5 yuan / degree), time period division (such as default peak 8:00-22:00) and other fixed values strongly related to external environment; the weight parameters include time period coefficient (such as peak elevator coefficient 1.5), load coefficient (such as full load elevator coefficient 1.2) and other adjustment values affecting the allocation ratio; the threshold parameters include abnormal electricity fluctuation threshold (such as single-day electricity surge exceeding 30%), user minimum effective elevator number (such as less than 2 times per month calculated as the basic value) and other risk control values.

[0057] The multi-factor calculation engine submodule 9 realizes dynamic electricity cost allocation by fusing three core dimensions of time-of-use electricity price, elevator use time period and elevator load rate. The calculation process takes the total elevator electricity cost of a certain community in a certain month as input, first splits the total electricity according to peak / valley time period and calculates the electricity cost of each time period; secondly, for each user, combines the elevator use times in peak / valley time period and the elevator load state during elevator use, and calculates the user contribution value by weighting the preset time period coefficient and load coefficient; finally, according to the proportion of all user contribution values, the total electricity cost is allocated to each user in proportion. For example, the total electricity consumption of a certain community in July is 300 degrees, of which 200 degrees is used in peak period (8:00-22:00) and 100 degrees is used in valley period (22:00-8:00), the local peak electricity price is 1.2 yuan / degree and the valley electricity price is 0.5 yuan / degree; user A uses the elevator 10 times in peak period and 5 times in valley period, and 3 times of elevator use is in full load state and the rest is in half load state; user B uses the elevator 8 times in peak period and 7 times in valley period, and has no full load elevator use record. The engine will complete segmented calculation and final allocation based on these data
[0058] Let the total electricity cost be C total , the peak period electricity cost C high and the valley period electricity cost C low :
[0059] C total =C high +C low ;
[0060] Wherein, C high=E high ×P high (peak period electricity E high times peak electricity price P high ), C low =E low ×P low (off-peak period electricity E low times off-peak electricity price P low ).
[0061] The contribution value Vi of user i is calculated by weighting the period coefficient and the load coefficient:
[0062] V i =n high,i ×α high +n low,i ×α low +n full,i ×β full
[0063] In the formula, n high,i is the number of times user i takes the elevator in the peak period, α high is the peak period coefficient; n low,i is the number of times user i takes the elevator in the off-peak period, α low is the off-peak period coefficient; n full,i is the number of times user i takes the elevator when it is full, β full is the full load coefficient.
[0064] The total contribution value Vtotal of all users is ∑ i=1 N Vi, N is the total number of users.
[0065] The electricity bill Ci that user i should share is:
[0066] ;
[0067] V total represents the sum of the contribution values of all users;
[0068] C i represents the electricity bill (yuan) that user i should share.
[0069] The internal setting of the result output verification submodule 10 is provided with a numerical verification unit, a rationality verification unit, a detail generation unit and an abnormal backtracking unit. The numerical verification unit ensures that the error is controlled within 0.1 yuan (a small deviation is allowed due to rounding) by calculating the difference between the sum of the electricity charges of all users and the total electricity charges; the rationality verification unit compares the electricity charges of a user this month with the historical data of the same period, and if the number of times a user takes the elevator increases by 50% but the electricity charges increase by only 10%, the abnormality is marked and manual review is triggered; the detail generation unit generates a user electricity charge allocation report based on the calculation process, including details such as elevator time period distribution, load participation times, coefficient weighting process, etc.; the abnormal backtracking unit records the full-process data of the algorithm calculation, and when the allocation result is complained by the user, the problem link can be quickly located.
[0070] The internal setting of the user interaction and service module 5 is provided with a user end application, a management end background, a data display component and an operation function component. The user end application takes APP or applet as the carrier, provides elevator ride times query and electricity charge detail viewing, including time period and load coefficient explanation, historical payment record tracing function, supports WeChat and Alipay online recharge, electronic invoice download and abnormal bill complaint; the management end background is developed based on Web, includes data dashboards such as total electricity of the community, electricity consumption ranking of each unit, proportion of non-payment users, supports time period division adjustment, for example, holiday peak extension, load coefficient modification, for example, increase of full load coefficient of old elevators, and other strategy configurations, as well as remote recovery of user rights, batch export of electricity charge report, such as Excel or PDF format, and other operations; the data display component visualizes user electricity consumption trend through line chart and column chart, and the operation function component integrates message push interface to realize real-time notification such as payment reminder and elevator abnormality prompt.
[0071] The internal setting of the intelligent control and early warning module 6 is provided with a permission control submodule, an abnormal early warning submodule and a predictive maintenance submodule. The permission control submodule is linked with the elevator recognition terminal to automatically disable the elevator ride permission of users who have not paid for two consecutive times, such as card swiping without response and face recognition prompting to pay first, and the permission is restored in real time after payment; the abnormal early warning submodule pushes electricity consumption abnormality and equipment failure warnings to maintenance personnel through analysis of electricity data, such as more than 30% of daily electricity consumption increase, and elevator state data, such as vibration frequency exceeding 5Hz and lasting for 10 seconds; the predictive maintenance submodule automatically generates maintenance plans based on historical elevator operation data, such as 100,000 times of door machine switching, combined with device life model, for example, replacing door machine bearings, and synchronizes to the to-do list of the management end background.
[0072] From the above, it can be seen that:
[0073] In the present application, through the cooperation of the dynamic intelligent allocation algorithm module and each functional module, the accuracy of electricity allocation is significantly improved. The data input integration sub-module standardizes and aligns the time dimension of multi-source data, such as unifying the card swiping ID and face feature code into a unique user identification, and aligning the scattered power and elevator records according to the daily / weekly / monthly cycle, to avoid calculation deviation caused by data format confusion or time misalignment; the integrity checking unit fills in the missing data through the supplementary recording mechanism to ensure the completeness and reliability of the basic data for algorithm calling. These links jointly ensure that the input data received by the multi-factor calculation engine is true and consistent, and the allocation result can more accurately reflect the actual electricity consumption behavior of the user.
[0074] In the present application, the parameter configuration management sub-module subdivides the parameters involved in the algorithm into basic parameters, weight parameters and threshold parameters, and supports intuitive adjustment by administrators through a visual interface. For different elevator rules of residential buildings and commercial office buildings, the "residential building template" or "commercial office building template" in the template library can be called to quickly configure parameters without the need to redevelop the algorithm; the template can be directly saved and reused after modification, reducing the system adaptation cost in different scenarios, and enabling the allocation rules to be dynamically optimized according to user needs or external environment (such as electricity price adjustment).
[0075] In the present application, the result output verification sub-module ensures the credibility of the allocation result through a multi-dimensional verification mechanism: the numerical checking unit strictly controls the error of the sum of the total electricity fee and user allocation (allowing a small deviation due to rounding), to avoid mistakes and omissions caused by calculation loopholes; the reasonableness verification unit compares historical allocation data of the user, and if there is an abnormal situation of increased elevator trips but abnormal fee growth, it will trigger manual review to prevent result distortion caused by data abnormalities or parameter misconfiguration; the detail generation unit provides an allocation report containing key information such as elevator time period and load coefficient (e.g. "User A contributes 42% due to 10 peak elevator trips with weighted coefficient"), which enables users to clearly trace the cost composition; the abnormal backtracking unit records the data of the entire calculation process, so that when the user has doubts about the result, the administrator can quickly locate the problem link (such as data input error or improper parameter configuration), solve the dispute in a timely manner, and enhance the user's trust in the system.
[0076] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application, therefore: any equivalent changes made according to the structure, shape, principle of the present application shall be covered within the protection scope of the present application.
