Referring to fig. 1, in one embodiment of the present application, there is provided a gas data modeling method based on dimensional analysis, the main steps of the method are described as follows:
s1: cleaning the acquired data through first repeated data, processing error data, and supplementing default data;
s2: performing dimension analysis on the acquired data subjected to the first repeated data cleaning, and storing the acquired data in an intermediate database;
s3: and carrying out gas data modeling based on the acquired data in the intermediate database.
Specifically, the gas data of the user is collected at regular time in the interval collection interval, which is determined according to the actual collection precision and can be set to any time interval of 1s, 5s, 10s, etc., in this embodiment, 10s is taken as an example; the collected data is collected user gas data; the error data is, for example, negative flow data, data having a jump compared with data of upstream and downstream, and the like, where the data of upstream and downstream refers to data located in a previous acquisition interval and a subsequent acquisition interval of the data. Normally collectedThe gas situation of the user gas data in the adjacent collection interval is not easy to have sudden jump, for example, the upstream collection data is 30m3The downstream data collection is 35m3H, current data acquisition is 100m3And h, jump possibly occurs, and data acquisition is wrong.
Specifically, in this embodiment, if the jump of the currently acquired data exceeds that of any one of the upstream and downstream data (data value × 10% × acquisition interval) compared with the upstream and downstream data, and the acquisition interval takes s as a unit, it is determined that the currently acquired data jumps, and the currently acquired data is cleaned.
In this embodiment, the supplementing the default data specifically includes: deleting the data value of the default data, supplementing the acquired data of the acquisition time of the default data, wherein the supplementing mode can be that a user gas use curve corresponding to the acquired data is fitted according to the time sequence, predicting the data value corresponding to the current default data according to the curve, for example, the acquired data at the 8 month 01 # 00 point of the current year is the default data, the default data value is A, deleting the default data value A, predicting the acquired data B at the current time according to the user gas use curve, and substituting the acquired data B into the data value of the acquired data at the 8 month 01 # 00 point of the current year.
The dimension analysis is to divide the data after the first re-cleaning into different dimensions, and the analyzed dimensions are divided into a year dimension, a quarter dimension, a month dimension, a week dimension, a day dimension, an hour dimension and the like.
The method for constructing the model can be as follows:
a floating ratio with respect to the average value is given based on the average gas usage every hour from monday to sunday in the week, and the maximum gas usage and the minimum gas usage every hour, and a regression curve of the gas usage is calculated.
And fitting a yearly gas utilization curve according to the total gas utilization amount of each month in the year and the gas utilization fluctuation of each month and according to the data of the past years.
The collected data are subjected to screening processing through the collected data cleaned and supplemented by the first repeated data, the data volume during modeling is reduced, error data are screened out, the accuracy of the model is improved, dimension analysis is performed on the collected data after the first repeated cleaning, the analysis speed of the model is improved, modeling analysis is performed on the gas using behaviors of the user, the gas using characteristics of the user are determined, a basis is provided for predicting the gas using behaviors of the user, and the main function of the model is to describe the gas using habits of the current user under a certain time span.
Referring to fig. 2, alternatively, in another embodiment, step S1 includes the following steps;
s11: sequencing according to the ascending order of time to obtain collected data;
s12: traversing the acquired data to eliminate default and invalid error data, supplementing the default data to clean the first repeated data, and recording the current valid data after the first repeated data is cleaned;
s13: clearing the transition data in the current valid data.
Specifically, the data are acquired according to the ascending time sequence, the acquired data are acquired in sequence, the acquired data are arranged, and when the data are cleaned, the logic between the data is better found, so that the data cleaning has certain logicality and basis, and the data can be better imported and exported.
The invalid data may be a negative data stream, or a data stream that should be growing for a certain period of time but exhibits a negative growth, etc.
Data can be screened one by one in a traversal mode, so that the situation that the prediction accuracy of the user gas data is low after the model is built due to the fact that problematic data are stored in the intermediate database is avoided.
The default data is supplemented with the following two ways: 1. fitting according to the acquired data of the current user in the time period containing the default data to form a fitting curve, and acquiring the acquired data of the time point corresponding to the current default data through the fitting curve; 2. and simulating the acquired data of the time point corresponding to the default data through the established user gas model to obtain the acquired data.
Through the first repeated data cleaning, part of useless data in the current acquired data is removed, the default data is supplemented, the acquired data is more complete to form effective data, and at the moment, jump data in the effective data is cleaned; processing the transition data after the first heavy data scrub has the following advantages: 1. when the default data is supplemented, because the default data is generated by means of simulation and calculation, the calculated value of the data is possibly larger than the actual value, so that the data is unreasonable, and the reliability of the acquired data stored in the middle database can be increased to a certain extent by cleaning the jump data; 2. by cleaning the transition data, the data in the intermediate database can have certain correlation with time, such as growth along with the growth of time, and better data statistics and modeling analysis can be performed.
Referring to fig. 3, alternatively, in another embodiment, the step S2 includes:

s22: determining an analysis dimension of the collected data;
s23: processing the collected data in the analysis time according to the analysis dimension;
s24: and storing the processed acquired data in a middle database.
Specifically, in this embodiment, the analysis time of the collected data is specifically the time interval of the current collected data collection, for example, if the collected data collected in the current year is analyzed, the analysis time is the current year. In other embodiments of the present application, the analysis time may be any time interval, such as one month, one week, etc.
The analysis dimension is a dimension into which the current data can be divided, for example, the analysis time of the currently analyzed collected data is one year, the analysis dimension may include a quarter dimension, a month dimension, a week dimension, a day dimension, and an hour dimension, for example, the whole year in 2020 is the collected data of the analysis interval, and the analysis dimension may include a quarter dimension, a month dimension, a week dimension, a day dimension, an hour dimension, and other time dimensions smaller than the year; for example, the analysis time is collected data of 8 months in 2020, the analysis dimension can be a week dimension, a day dimension and an hour dimension, and through the analysis dimension, the gas data of the user can be purposefully obtained, so that the data analysis, the calling and the checking are facilitated, the gas usage habit of the user is described to a certain extent by using the gas usage model established by various analysis dimensions, and a certain basis can be provided for predicting the gas usage behavior of the user and judging the gas usage abnormity.
In this embodiment, the analysis time of the collected data is determined, that is, the collected data is arranged according to time sequence, and then the data is processed according to the analysis dimension, where the specific processing mode is as follows: the collected data are divided according to the dimension with the shortest time in the time sequence, then the collected data are combined into the time dimension with longer time through the time dimension with the shortest time to establish a plurality of dimensions, specifically, the collected data can be divided by taking the hour as the minimum unit, then the day data are formed by integrating the data of all the hour dimensions on the day, and the data integration effect is better.
Referring to fig. 4, alternatively, in another embodiment, the step S3 includes:
s31: acquiring analysis data of a minimum granularity dimension, and eliminating invalid data;
s32: acquiring the time span of the model;
s33: obtaining each attribute value of the minimum granularity dimension data of the model under the time span;
s34: the model is stored.
Specifically, in this embodiment, the invalid data includes default data, transition data, error data, and error data determined to be erroneous based on data analysis, and the data determined to be erroneous based on data analysis may include data in which deviation from a curve trajectory exceeds a predetermined value based on curve determination fitted to collected data collected a plurality of times in any one dimension higher than the minimum granularity dimension. For example, the minimum granularity dimension is an hour dimension, and a curve is formed by fitting data of an analysis dimension such as a day dimension, a week dimension and the like which are higher than the hour dimension.
The time span of the model, i.e. the time period of data collection contained in the model, such as the data of the month of 8 months in 2021, is obtained, and under the time span, the model contains the data of the analysis dimension smaller than or equal to the unit of the time span, for example, the model of 8 months in 2021 contains the data of the week dimension, the day dimension and the hour dimension.
The attribute values comprise average temperature, maximum temperature, minimum temperature, temperature fluctuation rate and other numerical values, and determine the approximate gas usage range of the user at a specific time point of each month and a specific time point of each week.

Specifically, the relations among the quarterly dimensions, the month dimensions, the week dimensions, the day dimensions and the hour dimensions are established, for example, when a data model of the quarterly dimensions is selected, the data of all the quarters are automatically associated and are displayed in a centralized manner; in other embodiments, data of the same nature and dimension may also be associated, for example, data of the autumn of 2020 may be acquired, and data of all autumn of the rest year may be associated, and integrated to form a user gas model. The data of required dimensionality can be called out at one time when data analysis is carried out, so that model checking and data comparison are facilitated.
