Referring to fig. 1, a flowchart of a method for intelligent file management and control according to an embodiment of the invention is shown, the method includes the following steps:
and S001, acquiring a data sequence of each data acquisition moment of each monitoring point in the archive.

The method comprises the steps of taking a sequence formed by data sequences of all data acquisition moments in m days of each monitoring point according to the ascending order of time as a long-term data sequence of each monitoring point in an archive, inputting the corresponding long-term data sequence of any one monitoring point as an algorithm, and carrying out sequence decomposition on the long-term data sequence of each monitoring point by using an STL sequence decomposition algorithm to obtain trend items, season items and residual items of each long-term data sequence, wherein the STL sequence decomposition algorithm is a known technology, and specific processes are not repeated. And secondly, carrying out mutation point detection on a seasonal item corresponding to each monitoring point by utilizing a BG sequence segmentation algorithm, taking a time interval between any two mutation points as one data period in a long-term data sequence of each monitoring point, for example, carrying out mutation point detection on a seasonal item of a long-term data sequence of an a-th monitoring point, taking a time interval between the 1 st mutation point and the 2 nd mutation point as a first data period of the a-th monitoring point, wherein the BG sequence segmentation algorithm is a known technology, and the specific process is not repeated.
In general, the temperature and humidity at each monitoring point have little change in a short time, that is, the fluctuation of the values of elements in the data sequence at each monitoring point in the same data period is small, but certain interrelation exists among the elements in the data sequence, and in order to influence the fluctuation of the data, the elements in the data sequence are weighted.
Based on the analysis, a weighting factor W is constructed, and is used for carrying out weighting processing on the data of each factor in the data sequence of each monitoring point, and calculating the weighting factor of the ith element in the data sequence of the a-th monitoring point
In the method, in the process of the invention,is the long-term variance of the ith element at monitoring point a,/->Is the distribution variance of the ith element in the b-th data period in the long-term data sequence of monitoring point a,/for the data sequence of monitoring point a>Is the number of periods corresponding to the long-term data sequence of monitoring point a, < >>Is the number of elements within the data sequence at each time instant of the monitoring point a.
Wherein the larger the distribution variance of elements in different data periods in the seasonal term of the long-term data sequence of the a-th monitoring point,The larger the value of (2), the first product factor +.>The smaller the value of (2); while the larger the data fluctuation in the seasonal term of the long-term data sequence of the a-th monitoring point, the larger the long-term variance of all elements, the second product factor +.>The larger the value of (2), the weighting factor +.>The smaller the value of (2).
So far, the weighting factors of each factor in the data sequence of each monitoring point are obtained and used for carrying out subsequent weighting processing on the data.
And step S003, acquiring the temperature and humidity coupling coefficient of each monitoring point at each data acquisition moment according to the data sequence and the weighting factors of all elements in the data sequence.
Further, a data period of each monitoring point at each data acquisition time is obtained, k adjacent times of each data acquisition time are obtained by using a k adjacent algorithm in the data period, a set formed by the k adjacent times according to time sequence is used as an adjacent time set of each monitoring point at each data acquisition time, the size of k takes a checked value of 10, and an adjacent time set of an a-th monitoring point t data acquisition time is recorded as. Secondly, obtaining a weighting factor of each element in the data sequence of each monitoring point, taking the product of the weighting factor and the element value as the weighted data value of the element, taking a sequence formed by the weighted data values of all the elements at each moment of each monitoring point according to the descending order of the weighting factors as the weighted element sequence at each moment of each monitoring point, and marking the weighted element sequence at the t moment of the a-th monitoring point as->The invention aims to realize the regulation and control of the temperature and the humidity in the archive by utilizing the integrated control system, so that the weighted data values corresponding to the temperature and the humidity are deleted from the weighted element sequences respectively, and +.>The sequence obtained by deleting the weighted data values corresponding to the temperature and the humidity is marked as a temperature related sequence +. >Humidity-related sequence->
Based on the analysis, a temperature and humidity coupling coefficient U is constructed, used for representing the coupling degree between temperature and humidity data at different moments of each monitoring point, and the temperature and humidity coupling coefficient at the moment t of the a-th monitoring point is calculated
In the method, in the process of the invention,is the first temperature difference value of the a monitoring point and the c monitoring point at the moment f; />、/>The weighted element sequences of the (f) th moment in the neighbor moment set of the (a) th monitoring point and the (c) th monitoring point t moment are respectively +.>Respectively weighted element sequences->、/>Corresponding temperature-dependent sequences,/->、/>Respectively the sequences->And->、/>And->Pearson correlation coefficient therebetween;

The element association stability of the t moment of the a-th monitoring point and the c-th monitoring point is k, and k is the moment number in the t moment neighbor moment set. />The larger the value of the temperature and humidity data of the a-th monitoring point and the c-th monitoring point is, the more stable the relevance of the temperature and humidity data of the a-th monitoring point and the c-th monitoring point is at the time t.
Is the temperature and humidity coupling coefficient at the time t of the a monitoring point, M is the number of monitoring points in the archive,、/>the method is characterized in that the mode, the average value and the +.f of element association stability of the a-th monitoring point and the c-th monitoring point at all times in a data period of the t time are respectively>Is a parameter regulating factor and has the function of preventing denominator from being 0 #>The size of (2) is 0.001.
The temperature and humidity coupling coefficient reflects the degree of mutual coupling between temperature and humidity data at different moments of each monitoring point. The greater the relevance between the corresponding elements of the temperature and humidity data in the data sequences of the a-th and c-th monitoring points at the moment f, the greater the relevance between the weighted element sequences and the temperature correlation sequenceThe smaller the correlation between the series of humidity correlations, the first metricAnd a second scale factor->The greater the difference between the first temperature difference +.>The larger the value of (2), the higher the first metric factor +.>And a third metric factor->The greater the difference between the first humidity difference +.>The greater the value of +.>The greater the value of (2);
the more stable the relevance of temperature and humidity data of the a-th and c-th monitoring points at the time t is, the more stable the value condition of the element relevance index in the neighbor time set at the time t is,the greater the value of (2); the more stable the distribution of element association stability of the a-th monitoring point and the c-th monitoring point at all times in the data period of the t moment is, the mode is- >Mean->The closer the size of ++>The smaller the value of (2), the first accumulation factor +.>The greater the value of (2); i.e. < ->The larger the value of (c) is, the stronger the coupling between temperature and humidity in the data sequence at the time t of the a monitoring point is. The temperature and humidity coupling coefficient considers the correlation relationship of different elements in the data sequence at each moment in the data period of the season term, and has the advantages of eliminating the influence of the correlation caused by the fluctuation of the monitoring data on the normal coupling relationship between the temperature and humidity data, and being beneficial to obtaining the prediction result with higher accuracy later.
So far, the temperature and humidity coupling coefficient of each monitoring point in the archive at each data acquisition time is obtained and used for calculating the self-adaptive moving step length in the follow-up firefly optimization algorithm.
And S004, acquiring the data time lag radius of each monitoring point at each data acquisition time based on the temperature association weighting sequence and the humidity association weighting sequence of the same data acquisition time of different monitoring points.
When the integrated control system sends a regulation command to each monitoring point in the archive, the time period when the temperature and humidity data at each monitoring point reach an ideal value is recorded as the regulation time period of each monitoring point, and the mutual influence relationship between the temperature and humidity data at each moment in the regulation time period is in a state of real-time change. For example, the regulation and control instruction is cooling, and the air conditioner in the archives begins to carry cold wind, and the time that needs is different when cold wind transmission arrives in the archives different position monitoring points, also can have certain loss in transmission process, and the influence relation between temperature and the humidity data also can change gradually.
In order to reduce the loss in the temperature and humidity regulation process and the influence of the space distance on the temperature and humidity regulation precision as much as possible, the invention utilizes each element in the obtained data sequence to establish a transaction database, and then counts the accumulated count of each transaction in the history data of m days to obtain a candidate 1-item set, wherein the 1-item set is used as the input of an Apriori algorithm, the threshold value of the minimum support degree is set to be 50%, the threshold value of the minimum confidence degree is set to be 80%, and the temperature and the humidity of the monitoring point are respectively calculatedThe degree is used as a target rule, a frequent item set with a strong association rule with temperature and humidity is obtained by using an Apriori data mining algorithm based on a transaction database, and the Apriori data mining algorithm is a known technology, and the specific process is not repeated. And taking the transaction in the frequent item set of the strong association rule with the highest confidence as the strong association task of the temperature and the humidity when the temperature and the humidity of the monitoring point are taken as the association rule respectively. Taking a sequence formed by weighted data values of strong correlation transaction corresponding elements of temperature and humidity at each moment of each monitoring point as a temperature correlation weighted sequence and a humidity correlation weighted sequence at each moment of each monitoring point, and taking the temperature correlation weighted sequence at the t moment of the a-th monitoring point Humidity-associated weighting sequence->
For any monitoring point, certain time lag exists in the influence of the temperature and humidity data at the moment t on the temperature and humidity data at the subsequent moment, namely, along with the gradual increase of the time interval between the subsequent moment and the moment t, the influence of the temperature and humidity data at the moment t on the temperature and humidity data at the subsequent moment gradually decreases, namely, the temperature and humidity data at each moment has an influence radius, and the historical temperature and humidity data at each moment cannot influence the temperature and humidity data beyond the influence radius.
Based on the analysis, a data time-lag radius R is constructed, used for representing the influence range of the temperature and humidity data of each monitoring point at each moment on the temperature and humidity data at the subsequent moment, and the data time-lag radius at the time t of the a-th monitoring point is calculated
In the method, in the process of the invention,is the single temperature related distance of the a-th and c-th monitoring points at the time f,/>、/>The temperature-related weighting sequences at the time f of the a-th monitoring point and the c-th monitoring point are respectively +.>Is the sequence->The DTW distance between the two is a known technology, and the specific process is not described again.
