Detailed Description
In order to further explain the technical means and effects adopted by the invention to achieve the preset aim, the following is a detailed description of specific implementation, structure, characteristics and effects of the omnibearing efficient heat dissipation host power operation monitoring method based on the internet of things according to the invention by combining the accompanying drawings and the preferred embodiment. In the following description, different "one embodiment" or "another embodiment" means that the embodiments are not necessarily the same. Furthermore, the particular features, structures, or characteristics of one or more embodiments may be combined in any suitable manner.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.
The invention provides a specific scheme of an omnidirectional efficient heat dissipation host power supply operation monitoring method based on the Internet of things, which is specifically described below with reference to the accompanying drawings.
Referring to fig. 1, a flowchart of a method for monitoring operation of an omnidirectional efficient heat dissipation host power supply based on the internet of things according to an embodiment of the present invention is shown, and the method includes the following steps:
step S001: and collecting multi-dimensional data of the host power supply during operation.
It should be noted that, in the course of performing coarse K-Means clustering on the collected multidimensional data, the embodiment needs to collect multiple dimensional data and distributes the dimensional data unevenly, and the cross boundary data points between clusters are continuously changed in the continuous updating process of the data, so that the membership weight value of the boundary data points in the updating process is unreasonably calculated. In the analysis process, different dimension data can be affected by the influence of uneven distribution on a clustering result, and in some dimension data, abnormality can exist, but in single dimension data, whether abnormality exists can not be judged, but in other dimension data, data distribution has obvious difference, for example, when voltage data is analyzed, the change of the voltage data is normal, but larger abnormality can occur in temperature data, humidity data and fan data. In addition, as new data are continuously acquired along with the development of time, in the process of continuously updating and clustering (which can be regarded as an incremental clustering mode), the continuous data updating also has an effect on the change of boundary data points, according to the content, the embodiment processes arbitrary dimension data, acquires the related dimension data of the dimension data and acquires the non-uniformity of the related dimension data, and further calculates the influence weight value of the data points of the dimension data; and combining the change in the local neighborhood of the boundary data point in the continuously updated clustering process to comprehensively acquire the self-adaptive membership weight value of the boundary data point so as to obtain an accurate clustering result.
Specifically, a plurality of sensors are arranged to collect data in an operational state during testing of a host power supply, wherein the data includes multi-dimensional data such as voltage dimension data, power dimension data, temperature dimension data, humidity dimension data, fan dimension data, and the like. Any one dimension data is recorded as current dimension data, wherein the acquisition frequency of each dimension data is set to be the same, and the model of the sensor is not set, and the method can be determined according to the specific implementation situation of an implementer.
Step S002: and acquiring relevant dimension data of the current dimension data and a non-uniformity degree value of the relevant dimension data.
For example, when the current dimension data is temperature dimension data, since a temperature change does not change significantly in a short time (i.e., a temperature change has hysteresis) and a temperature change process is more careful in a monitoring process, when analyzing the temperature dimension data, it is necessary to consider dimension data related to the temperature dimension data, and to characterize a change in the temperature dimension data by a change in other dimension data, and therefore it is necessary to analyze dimension data related to the current dimension data. When the self-adaptive membership weight value of the boundary data points among clusters of the current dimension data is analyzed, the change of the current dimension data of the self-adaptive membership weight value needs to be considered, and meanwhile, the data distribution non-uniformity degree of the related dimension data also needs to be considered.
1. And acquiring relevant dimension data of the current dimension data.
Presetting a threshold valueWherein the present embodiment is +.>Examples are described, the present embodiment is not particularly limited, wherein +.>Depending on the particular implementation.
Specifically, the pearson correlation coefficient of the current dimension data and other dimension data is calculated; if the pearson correlation coefficient of the dimension data and the current dimension data in the other dimension data is larger than the preset threshold valueAnd if the dimension data has correlation with the current dimension data, taking the dimension data as the correlated dimension data of the current dimension data, and similarly, acquiring all correlated dimension data of the current dimension data. And recording the relevant dimension data of the current dimension data as relevant dimension data.
So far, the relevant dimension data of the current dimension data is obtained.
2. And acquiring the non-uniformity degree value of the related dimension data.
It should be noted that, the degree of non-uniformity value of the relevant dimension data is related to the data spatial distribution of the relevant dimension data, but the degree of non-uniformity value of the relevant dimension data, which is expected in the embodiment, is the influence of the data change of the current dimension data, that is, the influence of not only the distribution non-uniformity, but also the distribution influence of the data change feature of the current dimension data, and if the distribution of other dimension data and the current dimension data have relevance, the distribution non-uniformity is smaller. The present embodiment thus performs weight influence calculation by combining the distribution of the data change characteristics with the current dimension data with reference to the data space distribution characteristics of the correlation dimension data itself.
(1) Acquisition of the firstData spatial distribution characteristics of each relevant dimension data.
Specifically, at the firstPerforming convex hull detection in the space of the data layer of the relevant dimension data to obtain the convex hull range with the maximum data in the space, obtaining a square area corresponding to the smallest external square of the convex hull range, and performing 25 equal division on the square area to obtain 25 areas, wherein the implementation is described by dividing the square area into 25 areas, and other embodiments are not limited specifically and depend on specific implementation conditions; the ratio of the average distance of the data points in each block to the side length of the block (the distances between all the data points in the block are obtained and summed to obtain the average value as the average distance of the data points) is recorded as the distance ratio, and a distance change curve is constructed according to the block sequence (from left to right and from top to bottom), wherein the abscissa of the curve is the sequence number of the block, the ordinate is the distance ratio corresponding to the block, then the>Data space distribution characteristics of the individual related dimension data itself>The calculation method of (1) is as follows:
;
in the method, in the process of the invention,indicate->Data space distribution characteristics of the relevant dimension data; / >Indicate->The data plane of the data of the relevant dimension data is +.>The ratio between the average distance of the data points in the individual tiles and the side length of the tile;indicate->The average of the ratio between the average distance of data points in all tiles and the side length of the tile in the data plane space of the respective dimension data.
To this end, obtain the firstData spatial distribution characteristics of each relevant dimension data.
(2) Acquisition of the firstThe relevant dimension data and the current dimension data change distribution characteristics.
It should be noted that, in the process of obtaining the influence of the data change distribution feature in this embodiment, the change and the first dimension of the current dimension data need to be consideredThe correlation of the changes in the relevant dimension data, but the changes in the current dimension data may be affected by the various dimension data.
Specifically, obtain the firstDimension distribution influence weight value +.>: in analysis->When the dimension distribution of the relevant dimension data affects, consider +.>The influence of the relevant dimension data is obtained, so that the time period in which other relevant dimension data cannot change is obtained, and the time period is analyzed, so +.>Wherein->Representing the total time period length of the multi-dimensional data when the host power supply is in operation, < > >Indicating except->The length of the time period occupied when other dimension data of the relevant dimension data is unchanged.

To sum up, the firstVariation distribution characteristics of each related dimension data and current dimension data>The calculation method of (1) is as follows:

To this end, obtain the firstThe relevant dimension data and the current dimension data change distribution characteristics.
According to the firstData space distribution characteristics of the individual related dimension data itself and +.>The variation distribution characteristics of the relevant dimension data and the current dimension data are obtained>The non-uniformity degree value of each relevant dimension data is calculated by the following expression:
;
in the method, in the process of the invention,indicate->A degree of non-uniformity value for each of the associated dimensional data; />Indicate->Data space distribution characteristics of the relevant dimension data; />Indicate->The change distribution characteristics of the relevant dimension data and the current dimension data; />An exponential function based on a natural constant is represented.
Thus, the non-uniformity degree value of the relevant dimension data is obtained.
Step S003: and obtaining an influence weight value of the relevant dimension data according to the non-uniformity degree value of the relevant dimension data of the current dimension data.
It should be noted that, by analyzing the influence weight value of the relevant dimension data, the boundary data point obtained by performing coarse K-Means on the multidimensional data when the host power supply is running is obtained, and the adaptive membership weight value between each cluster is obtained, wherein the larger the influence weight value of the relevant dimension data is, the more the distribution characteristics of the corresponding relevant dimension data and the current dimension data are analyzed. Therefore, the step is combined with the non-uniformity degree value of the related dimension data, and the allowable error of the similarity of the data distribution of the local range of the related dimension data and the local range of the current dimension data is obtained in a self-adaptive mode, so that the influence weight value of the related dimension data is obtained.
1. An allowable threshold fluctuation value of the relevant dimension data is acquired.

Similarly, data points of a local range of boundary data points of the relevant dimension data are obtained.
To this end, data points of a local range of boundary data points of the current dimension data and the related dimension data are obtained.
According to the phaseData points of the current dimension data and the data points of the local range of boundary data points of the current dimension data and the related dimension data are obtained by the allowable threshold fluctuation value of the dimension data and the data points of the local range of the boundary data points of the current dimension data and the related dimension dataSimilarity in data spatial distribution between data points of the respective related dimension data is calculated as:

So far, the influence weight value of the relevant dimension data is obtained.
Step S004: and according to the change of the data point distribution characteristics in the continuous incremental clustering process, and combining the influence weight value of the related dimension data to acquire the self-adaptive membership weight value of the boundary data point.
Because new current dimension data is continuously acquired with the development of time, in the process of continuously updating and clustering (which can be regarded as a mode of incremental clustering), the continuous current dimension data updating also has an effect on the change of boundary data points of the current dimension data, so that the membership weight value needs to be adjusted in the process of continuously updating according to the incremental clustering when the adaptive membership weight value is acquired.
It should be further noted that, in the process of incremental clustering after the current dimension data is newly added, the boundary data point corresponding to the current dimension data changes, and in this embodiment, when the membership weight value of the boundary data point of the updated current dimension data is obtained, the change from the boundary data point of the current dimension data updated last time to the boundary data point of the current dimension data needs to be considered.
Specifically, the first dimension of the current dimension dataThe boundary data point is about>Self-adaptive membership weight value of individual clustersThe calculation method of (1) is as follows:

in the method, in the process of the invention,represents the +.>The boundary data point is about>Self-adaptive membership weight values of the clusters; />The +.f representing the current dimension data now>Data points within the local range of the boundary data points to +.>Average Euclidean distance of the cluster centers; />Data points within the local range of all boundary data points representing the last current dimension data to +.>Average Euclidean distance of the cluster centers; />Total number of relevant dimension data representing current dimension data; />Indicate->Influence weight values of the relevant dimension data; />Indicate->The +. >A number of data points within a corresponding time period range of the plurality of boundary data points; />Indicate->The +.>Of the data points within the corresponding time range of the boundary data points, satisfy +.>Is (wherein +.>Indicate->The +.>Data distribution characteristics of data points within a time range corresponding to each boundary data point, < ->Indicate->An average data distribution characteristic of the individual clustered data points; />Indicate->Allowable threshold fluctuation values for the individual related dimension data).
Wherein,weight value representing change course of incremental clustering, if the value is larger, the average Euclidean distance is increased after updating, and the weight value corresponds to the +.>The boundary data point is about>The smaller the adaptive membership weight of the clusters; />The influence degree of the related dimension data is expressed, and if the influence weight value of certain related dimension data is larger, the corresponding distribution characteristics of the data points in the same time period range of the related dimension data are needed to be considered; />The larger the distribution of boundary data points indicating the relevant dimension data is, the more approaching +.>Clustering, boundary data points of the corresponding related dimension data are corresponding to +. >The greater the membership weight of the individual clusters. />
And similarly, obtaining the self-adaptive membership weight value of each boundary data point of the current dimension data for each cluster.
So far, the self-adaptive membership weight value of the boundary data point of the current dimension data to the cluster is obtained.
Step S005: and carrying out coarse K-Means clustering according to the self-adaptive membership weight value of the boundary data point to obtain an accurate detection result.
And (3) according to the self-adaptive membership weight value of each boundary data point of the current dimension data to each cluster, re-calculating the mean center of the weight value and the boundary data point in the original iterative updating process, wherein the process is a known technology and is not repeated in the embodiment, so that an accurate coarse K-Means clustering result is obtained. Similar operations result in clustering results of other dimensions. The clustering result is stored as a monitoring model, multidimensional data acquired in the operation monitoring process of the host power supply is added into the monitoring model, and the classification is carried out by calculating Euclidean distances from newly added dimensional data points to the centers of all clusters in the monitoring model. The embodiment with the largest data point number in the cluster in the monitoring model is considered as a normal cluster type, and the corresponding classification result of the new data is accurately monitored.
