Technical Field

[0001] The present invention relates to the field of tablet computer intelligent management, and in particular to a tablet computer intelligent management system and method. Background Art

[0002] With the continuous development of the digital age, tablet computers have been widely used in various fields. In particular, tablet computers have played an important role in corporate office work. However, as the application scenarios of tablet computers in enterprises become increasingly complex and the number of users continues to increase, tablet computer management issues have become more difficult. Traditional tablet computer management relies too much on manual labor, and management efficiency and accuracy cannot be guaranteed.

[0003] In the process of tablet computer intelligent management, the determination of hardware status and tablet user usage status is particularly important. However, the existing tablet computer intelligent management cannot monitor and determine the hardware status and tablet user usage in an all-round manner, which affects the user experience and work efficiency. At the same time, there are cases where tablet computer users steal corporate secrets and the work status continues to be sluggish. Therefore, how to monitor and determine the hardware status and tablet user usage in an all-round manner is a technical problem that needs to be solved.

[0004] In order to solve the above defects, a technical solution is now provided. Summary of the invention

[0005] In order to solve the technical problems raised by the above background technology, the present invention is proposed. The embodiments of the present invention provide a tablet computer intelligent management system and method.

[0006] The purpose of the present invention can be achieved through the following technical solutions: A tablet computer intelligent management system includes a data acquisition module, a hardware module, a user module, a verification module and a warning module.

[0007] The data acquisition module is used to collect processor information, battery information, screen information and user information, and send them to the hardware module and the user module;

[0008] The hardware module includes a processor unit and a pool screen unit;

[0009] The hardware unit analyzes the processor information, the processor cache, micro-operation and branch prediction status, obtains the tablet computer processor status value, and sends it to the verification module;

[0010] The pool screen unit determines and analyzes the battery redox reaction state and the screen usage state of the battery information and the screen information to obtain a positive pool screen state value of the tablet computer;

[0011] The user module performs user interaction and sharing status analysis on the user information to obtain a user status value of the tablet computer;

[0012] The verification module performs a comprehensive operation status analysis of the tablet computer on the tablet computer processor status value, the tablet computer pool screen status value and the tablet computer user status value, and compares them with the set threshold value to obtain a corresponding warning signal;

[0013] The warning module performs a warning operation on the signal generated by the verification module.

[0014] Furthermore, the tablet computer processor status value analysis steps are as follows:

[0015] The total number of accesses and misses of the conversion lookaside buffer is obtained through a hardware performance monitoring tool within a certain monitoring period, and the miss number is divided by the total number of accesses to obtain a conversion lookaside buffer miss rate. The number of branch prediction errors and the total number of branch instructions in the entire program are obtained through a hardware performance monitoring tool, and the number of branch prediction errors is divided by the total number of branch instructions to obtain a branch prediction error rate. The conversion lookaside buffer miss rate, branch prediction error rate and cache hit rate are calculated with the micro-operation state value Wz to obtain a tablet computer processor state value Clz.

[0016] Furthermore, the micro-operation state value analysis steps are as follows:

[0017] S1: Obtain the capacity value of the micro-operation queue through the processor's technical documentation. Within a certain monitoring time Yt, count the number of micro-operations entering the queue Ds through the processor's internal counter. Divide the number of micro-operations entering the queue Ds by the certain monitoring time Yt to obtain the micro-operation queue entry rate Rl.

[0018] S2: within the same monitoring time interval Yt, the number of operations executed Bs is counted by the counter inside the processor, and the number of operations executed Bs is divided by a certain monitoring time Yt to obtain the execution rate value Bl of the micro-operation;

[0019] S3: When the micro-operation enqueue rate value Rl is greater than the micro-operation execution rate value Bl, the capacity value Rl of the micro-operation queue is divided by the difference between the micro-operation enqueue rate value Rl and the micro-operation execution rate value Bl to obtain the overflow duration value of the micro-operation queue, and the micro-operation enqueue rate value Rl, the micro-operation execution rate value Bl, and the overflow duration value Yt are calculated to obtain the micro-operation status value Wz.

[0020] Furthermore, the cache hit rate analysis steps are as follows:

[0021] Step 1: Use the performance monitoring tool to obtain the access count parameters of the first-level cache, second-level cache, and third-level cache. The specific parameters are the write access count value and the read access count value, and are marked as Xf respectively. i and Df i, i represents the number of the cache block. Through the mapping rules between cache blocks and memory data blocks, the formula is used to calculate the access value Zf of each memory data block. j , j represents the number of the memory data block, the size of the memory data block is obtained through the database management system, marked as Nd, and the memory data block number, read access times, and write access times are stored in the data structure;

[0022] Step 2: Set the access value threshold T1 to determine whether each memory data block belongs to the working set, traverse and record the structure of the access value of each data block, the structure of the access value is specifically a hash table, when the access value of each data block is greater than or equal to the set access value threshold T1, the data block is classified into the working set, and the starting address and ending address of each memory data block in the working set are obtained;

[0023] Step 3: Count the number of times each memory data block is accessed in the first-level cache, the second-level cache, and the third-level cache, and calculate the access ratio of each memory data block in each cache level. When the access ratio of a memory data block in the first-level cache exceeds 0.5, the memory data block is determined to be a core part, and the access value threshold T1 of the memory data block is changed to T2. Follow step 2 again to obtain a new working set, and re-obtain the start address and end address of each memory data block in the new working set, and mark them as XQd respectively. k and XZd k , k represents the number of each memory data block in the new working set;

[0024] Step 4: According to the formula Gz k =XZd k -XQ k +Nd, get the working set value Gz of each memory data block k , and sum up the working set values ​​of each memory data block to calculate the total working set value Gz of the tablet computer, obtain the cache value of the tablet computer through the tablet computer task manager, divide the cache value of the tablet computer by the total working set value of the tablet computer, and multiply it by the correction factor coefficient to obtain the cache hit rate.

[0025] Furthermore, the steps for analyzing the positive value of the pool screen shape of the tablet computer are as follows:

[0026] By sending a specific color change signal to the tablet screen and capturing the color change value with a high-speed camera, the color change is terminated when it reaches the set threshold, and the duration from the color change to the termination is calculated and marked as the pixel response duration value. The screen display color value is measured by a spectrophotometer, and the difference is made with the standard color value, and the absolute value is taken and marked as the color deviation value. The highest brightness value and the lowest brightness value of the screen are measured by a brightness meter under different lighting environments, and the highest brightness value of the screen is subtracted from the lowest brightness value of the screen to obtain the contrast of each environment. The contrast under different environments is subtracted and the absolute value is calculated to obtain the contrast stability difference value. The pixel response duration value, the color deviation value and the contrast stability difference value graph are constructed to obtain the screen state abnormality value of the tablet computer;

[0027] Multiply the tablet computer's battery cyclic volt-ampere value by the weight factor coefficient w1 to obtain a product value of one, multiply the tablet computer's screen condition value by the weight factor coefficient w2 to obtain a product value of two, divide the product value one by the product value two, and multiply by the correction factor coefficient to obtain the tablet computer's battery screen condition positive value Cpz.

[0028] Furthermore, the steps of analyzing the cyclic volt-ampere value of the battery of the tablet computer are as follows:

[0029] A linearly varying voltage signal is applied to the battery electrode of the tablet computer, and the voltage is scanned from the set initial voltage to the set termination voltage, and then the set termination voltage is scanned to the set initial voltage, and the current value formed by the redox reaction on the surface of the battery electrode is recorded. The set voltage is used as the horizontal coordinate, and the collected current value is used as the vertical coordinate to draw a cyclic voltammetry curve. The position value and peak value of the redox peak on each cycle curve are counted, and the position value of each redox peak in the coordinate graph is subtracted from the position value of the adjacent redox peak in the back to obtain the position value adjacent value, and the adjacent value of the adjacent position value in the back position value in the coordinate graph is subtracted from the adjacent value of the adjacent position value in the front position value, and the sum is obtained to obtain the peak position deviation value, and the average value of each peak value is counted, and the peak average value is subtracted from each peak value, and the absolute value is taken and summed to obtain the peak deviation value, and the peak position deviation value and the peak deviation value are summed and multiplied by the corresponding proportional factor coefficient to obtain the total peak deviation value, and the total peak deviation value is calculated by the inverse, and multiplied by the correction factor coefficient to obtain the redox peak stability value, and the formula is calculated to obtain the deviation value Dc of each peak. g , g is the number of the redox peak, the total redox peak deviation value Dc is calculated by the formula, the redox peak stability value is divided by the total redox peak deviation value, and multiplied by the correction factor coefficient to obtain the battery cyclic volt-ampere value of the tablet computer.

[0030] Furthermore, the tablet computer user status value analysis steps are as follows:

[0031] Create an n×n adjacency matrix Q with enterprise tablet users, and the number of computer users is n. When computer user x and computer user y send messages and comments to interact, Qxy=1, and when there is no interaction, Qxy=0. The formula calculates the average degree centrality value Zx of computer user x, obtains the department of each enterprise tablet user, and sets the employee degree standard centrality value according to the department. When the computer user is at the leadership level, the computer user's standard degree centrality value is multiplied by the coefficient value 1.2. The centrality value of the tablet user is compared with the obtained standard degree centrality value to analyze the degree centrality deviation of the tablet user; when computer user x and computer user y interact directly, the corresponding path length is 1. If computer user x and computer user y need to interact through other computer users, the shortest path length is calculated through breadth-first search, and a new Matrix G, where Gxy represents the shortest path length from computer user x to y. For each computer user g, for each pair of computer users x and y, if the path Gxy is greater than 1, check whether the path passes through computer user g. If so, increase the intermediate value of computer user g by 1. Judge each pair of computer users in turn to obtain the total intermediate count value cung of computer user g. The intermediate center value Zx of computer user k is calculated by formula. The average intermediate center value of computer users over a period of time is counted. The intermediate center value of a certain period of time monitored recently is compared with the average intermediate center value to analyze the change rate of the intermediate center value of the computer user. The number of file sharing activities of tablet computer users, the number of external device connections and the number of logins of different user accounts within a certain period of time are monitored through network monitoring tools, and they are summed to obtain the total connection value of the tablet computer user.

[0032] The tablet user's degree center deviation, the computer user's intermediate center value change rate, and the tablet user's co-connection value are calculated to obtain the tablet user's state value Pzz.

[0033] Furthermore, the corresponding warning signal analysis steps are as follows:

[0034] The tablet computer processor status value Clz, the tablet computer pool screen status positive value Cpz and the tablet computer user status value Pzz are calculated by the formula to obtain the tablet computer comprehensive status positive value ZZZ;

[0035] When the tablet computer's overall positive value is less than the preset tablet computer's overall positive threshold, a tablet computer status abnormality alarm is generated, the tablet computer user status value is divided by the tablet computer's overall positive value, and multiplied by the correction factor coefficient to obtain the tablet computer user evaluation value, and the tablet computer hardware maintenance signal and the tablet computer user abnormality signal are obtained by analysis.

[0036] Furthermore, the warning operation analysis steps are as follows:

[0037] When a tablet computer hardware maintenance signal is received, an early warning is issued to the tablet computer hardware, and a warning operation 1 is executed;

[0038] When an abnormal signal from the tablet computer user is received, an early warning is issued to the tablet computer user, and a second warning operation is performed.

[0039] Further, the following steps are included:
