[0001] The present invention relates to the technical field of resource management, and in particular to a cloud resource management system and method based on an education platform. Background Art

[0002] As educational resource websites continue to emerge across the country, the issues of how to provide rich information to a wide range of users, how to strengthen the construction of information resource libraries, how to expand the scope of shared information resources and how to rationally use educational resource libraries have become not only the main difficulties faced by schools that have built networks, but also one of the important indicators for testing the level of modern education in schools.

[0003] The education platform can uniformly manage various educational resources, including course resources, teacher resources, equipment resources, etc., thereby improving the utilization efficiency of educational resources. At the same time, the education platform can also realize the centralized management and sharing of various educational resources through information technology, thus avoiding the problem of resource dispersion and repeated waste.

[0004] There are various cloud resource data in the education platform. In order to better achieve the management effect of cloud resources, different types of resource data are generally stored in different storage spaces; however, when a large number of users enter the same storage space to browse the same resources at the same time within a certain period of time, it is easy to cause the storage space to fail to operate, the number of resources cannot be displayed, and even cause the education platform to freeze and paralyzed; therefore, how to improve the platform's security performance and resource usage performance based on users' historical browsing habits of resources has become an urgent problem to be solved. Summary of the invention

[0005] The purpose of the present invention is to provide a cloud resource management system and method based on an education platform to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a cloud resource management method based on an education platform, comprising the following steps: Step S100: Collect all resource data in the education platform to form a cloud resource set; obtain cloud storage space for each resource data in the cloud resource set respectively, and form different storage nodes respectively; collect information of all users authorized to log in to the education platform and historical browsing records of each resource data by the corresponding users to form a user browsing set; mark the time node when each resource data in the cloud resource set is browsed by any user, and form a node information set of each resource data respectively; Step S200: sequentially capturing the time interval between any two adjacent time nodes and the browsing volume ratio of the corresponding resource data according to the node information set; constructing a browsing change curve according to the time interval and the browsing volume ratio, and analyzing whether the browsing status of each resource data is abnormal according to the browsing change curve; The process of constructing the browsing change curve according to the time interval and the browsing volume ratio in the above steps is: weighting the time interval and the browsing volume ratio, and constructing the browsing change curve with the number of browsing times as the horizontal axis and the weighted state as the vertical axis; Step S300: extract all resource data with abnormal browsing status and corresponding time nodes of abnormal occurrence to form abnormal resource sets respectively; obtain storage nodes of each abnormal resource in the abnormal resource set respectively, and form a node relationship diagram with the direction and distance of information transmission between each abnormal resource and each resource data; capture the abnormal time nodes of each abnormal resource in the abnormal resource set, obtain user information browsing each abnormal data at the abnormal time node and the historical browsing records of the corresponding user; then construct a resource selectivity model according to the time length value and distance length value of the resource data corresponding to each time node in each historical browsing record; Step S400: Obtain all user information captured by each abnormal resource at the corresponding abnormal time node, extract the resource selectivity model value of the corresponding user respectively, and match the response time of each abnormal resource to the corresponding user according to the size of the model value.

[0007] Furthermore, step S100 includes: Step S110: Collect all resource data in the education platform to form a cloud resource set; respectively obtain cloud storage space for each resource data in the cloud resource set to form different storage nodes; collect all user information authorized to log in to the education platform and the corresponding user's historical browsing records of cloud resources to form a user browsing set; In the above steps, each storage node stores a type of resource data, so the cloud storage space of each resource data is different. When browsing resource data, the cloud storage space entered is different, which will not affect the memory of other spaces; using distributed storage space, dynamic management of resource data is realized, improving the user's experience of using resource data; The historical browsing records in the user browsing set in the above step represent the cloud resource browsing data of the corresponding user in time series; Step S120: Mark the time nodes when each resource data in the cloud resource set is browsed by any user, and form a node information set A={t1, t2, …, tn} for each resource data, where t1, t2, …, tn respectively represent the time nodes when each resource data is browsed for the 1st, 2nd, …, nth time.

[0008] Further, step S200 includes: Step S210: sequentially capture the number of views xi of each resource data at any time node ti according to the node information set A; respectively obtain the time interval ti-t(i-1) between any two adjacent time nodes, where t0=0 when i=1, and the corresponding ratio of views x(i-1) / xi between any two adjacent time nodes; obtain the browsing state formula at any time node ti according to the time interval and the ratio of views between any two adjacent time nodes: Hi=α1*[ti-t(i-1)]+α2*[x(i-1) / xi], where α1 represents the weight value of the time interval, and α2 represents the weight value of the ratio of views; The process of analyzing the browsing state formula at any time node ti in the above steps includes: For example, the number of views {x1, x2, …, xn} of a certain resource data at each time node in the node information set A={t1, t2, …, tn} is obtained, where x1, x2, …, xn represent the number of users browsing a certain resource data at time nodes t1, t2, …, tn respectively; the time intervals of t1, t2, t3, … are calculated in sequence as t1, t2-t1, t3-t2, …; the ratios of the views of x1, x2, x3, … are calculated in sequence as 0, x1 / x2, x2 / x3, …; at this time, the browsing status formula at any time node ti is obtained: Hi=α1*[ti-t(i-1)]+α2*[x(i-1) / xi]; Step S220: Obtain the browsing state formula Hi at any time node ti, then use the browsing times i as the horizontal coordinate and the browsing state value Hi as the vertical coordinate to construct a two-dimensional rectangular coordinate system to form a browsing change curve. The browsing times i in the above steps are respectively composed of regular numbers such as 1, 2, 3, ..., indicating that the time node when the i-th resource data is browsed is ti; Step S230: sequentially traverse the slope values ​​between each adjacent coordinate point in the browsing change curve, and make the absolute value of the difference between the current traversed slope value and all the slope values ​​obtained previously, and then form a difference set B of the current traversed slope value; capture the number of slope differences in the difference set B that are greater than the threshold β, and when s / |B| is greater than the proportion threshold γ, it indicates that the browsing state of the time node corresponding to the difference set B is abnormal; where s represents the number of slope differences greater than the threshold β, and |B| represents the number of slope differences in the difference set B; The purpose of the above steps is to analyze whether the browsing state value Hi changes abnormally as the number of browsing times i increases in the browsing change curve; when the proportion of the number of slope differences greater than the threshold β exceeds the threshold, it means that the browsing state value corresponding to the coordinate point is very different from that of other coordinate points, further indicating that the browsing state of the resource data at the corresponding time node is abnormal; By weighting the number of views and time intervals of each resource data, and confirming the browsing status values ​​at different time nodes, it is beneficial to analyze the status anomalies of each resource data at each time node, and facilitate subsequent analysis of the reasons for anomalies when different users browse each resource data.

[0009] Furthermore, step S300 includes: Step S310: extract all resource data with abnormal browsing status and the corresponding time nodes of abnormal occurrence, and form abnormal resource sets respectively; set any abnormal resource data in the abnormal resource set as target abnormal data, and obtain the storage nodes of each resource data respectively, and construct a two-dimensional plane coordinate system with the storage node of the target abnormal data as the origin; simulate the direction and distance from the origin to the storage node of each resource data based on the direction and distance of information transmission between the target abnormal data and each resource data, and form a node relationship graph; wherein the storage nodes of each resource data in the node relationship graph are all assigned position coordinates, and together with the storage nodes of the target abnormal data, form a node relationship graph; Step S320: capturing the abnormal time node of the target abnormal data according to the abnormal resource set, further obtaining the user information browsing the target abnormal data at the abnormal time node and the historical browsing records of the corresponding user, forming a browsing record set C={c1,c2,…,cm}, where c1,c2,…,cm represent the historical browsing records of the 1st, 2nd,…,mth users browsing the target abnormal data at the abnormal time node; obtaining the time node of any historical browsing record and the corresponding browsed resource data in the browsing record set C, recording the time interval between two adjacent time nodes in sequence, and assigning the time interval to the resource data corresponding to each subsequent time node, respectively forming the time length value P of each resource data in any historical browsing record, wherein the time length value of the first time node is 0; Step S330: Capture the position coordinates of each resource data in any historical browsing record according to the node relationship diagram, calculate the distance value of the resource data between two adjacent time nodes in turn, and assign the distance value to the resource data corresponding to the next time node, respectively forming the distance length value Q of each resource data in any historical browsing record. When the distance length value is larger, it means that the span of the user browsing resource data is larger and has no regularity; construct the resource selectivity model Yj=ρ*[∑ (j-1) P*Q] / (j-1), where j represents the number of time nodes and j>1; By analyzing the simulated distance between target abnormal data and each resource data, a node relationship graph is constructed. The relationship between each resource in the historical browsing record is analyzed based on the node relationship graph to confirm the distance length value, which is conducive to analyzing the regularity of user browsing resource data and facilitating the subsequent construction of the user's resource selectivity model. In the above steps, when the time length value is larger and the distance length value is longer, it means that the user has a longer time interval for entering the education platform to browse resources and the cloud storage space spanned is larger. At this time, the user has greater selectivity for resources in the education platform.

At this time, the user has greater selectivity for resources in the education platform.

[0027] Step S400: Obtain all user information captured by each abnormal resource at the corresponding abnormal time node, extract the resource selectivity model value of the corresponding user respectively, and match the response time of each abnormal resource to the corresponding user according to the size of the model value.
