Description

Technical Field

[0001] The present invention relates to the technical field of terminal equipment management, and in particular to a control system and method for intelligent terminal equipment. Background Art

[0002] Through network sharing technology, the same IoT terminal device can be used by multiple users. Shared IoT devices improve the utilization rate of IoT smart terminal devices, reduce the number of deployed application layer terminal devices in the system, and save device hardware and network resources. However, since shared IoT terminal devices will open calling protocols, users who call the same IoT device will have multiple identities, making it difficult to supervise the security of terminal devices. At the same time, deploying complex security management strategies will occupy a large amount of operating resources and is not suitable for deployment on terminal devices. Summary of the invention

[0003] The object of the present invention is to provide a control system and method for an intelligent terminal device to solve the problems raised in the prior art.

[0004] To achieve the above object, the present invention provides the following technical solution: a control method for an intelligent terminal device:

[0005] Step S100: obtaining configuration information of the terminal device, distinguishing the operation mode of the terminal device by the difference of configuration parameters corresponding to the configuration items in the configuration information, and saving the obtained operation mode in the operation mode comparison library;

[0006] Step S200: a terminal device is set as a target device, and a security check is performed on the target device. When the target device passes the check safely, the operation records of each operation data item of the target device are obtained, and the operation records of the operation data items within a unit time range are normalized to obtain a time-dependent change function of the operation data items, and the operation data item with the largest degree of difference in the change function is obtained as a characteristic operation data item;

[0007] Step S300: respectively obtain the change functions corresponding to the characteristic operation data items, superimpose the change functions to obtain the reference function, use the ratio of the average amplitude value of each change function to the average amplitude of the reference function as the weight coefficient of each change function, and collect the characteristic operation data items, reference functions and weight coefficients under all operation modes of the target device to form a characteristic database;

[0008] Step S400: During the current use of the target device, a security check is performed on the target device. When the target device fails the security check, the current operation mode of the target device is obtained, a characteristic operation data item corresponding to the operation mode is obtained from an operation mode comparison library as a target operation data item, and instruction information including an operation record requesting the target operation data item is sent to the target device;

[0009] Step S500: After receiving the instruction information, the target device submits the operation record of the target operation data item during the current use process, obtains the weight coefficient corresponding to the current operation mode of the target device from the feature database, performs weighted operation on the operation record, and obtains the target function;

[0010] Step S600: Obtain a reference function corresponding to the current operation mode of the target device, compare the target function with the reference function, and when there is a difference between the target function and the reference function, issue an alarm to the administrator of the target device.

[0011] Furthermore, step S100 includes:

[0012] Step S101: Collect all configuration items of the target device to obtain a device configuration list, wherein the i-th configuration item of the target device is recorded as Ai, and the configuration parameter corresponding to the i-th configuration item is recorded as Vai. (Ai, Vai) is composed of a configuration pair. In the process of collecting device configuration information once, the corresponding configuration parameter information of each configuration item is collected into the configuration list to obtain a device configuration record;

[0013] Step S102: Collecting a number of device configuration records, and classifying the device configuration records according to the same configuration parameters of all the same configuration items, wherein one type of device configuration record corresponds to one type of operation mode, and the device configuration records are device configuration records collected after the target device passes the security detection;

[0014] Step S103: extracting configuration items corresponding to each type of operation mode respectively, and collecting the correspondence between each type of operation mode and the configuration items into an operation mode comparison library.

[0015] Further, step S200 includes:

[0016] Step S201: collecting the operation mode of the target operation device, obtaining a unit time period of duration T, and collecting the operation records of various operation data items of the target device in the collected unit time period respectively;

[0017] Step S202: Record the ratio of the actual operation data value in the operation record to the operation value under the maximum operation load as the load rate, convert the change relationship of the actual operation value of each operation record over time into the change relationship of the load rate over time, draw the function of the load rate of each operation data item over time, and obtain the change function of the load rate, and arrange the change functions according to the order of the function means from small to large to obtain the change function sequence Y;

[0018] Step S203: Obtain the change function corresponding to the maximum function mean in the change function sequence Y, record it as ymax, and the change function corresponding to the minimum function mean as ymin, and remove ymax and ymin from the change function sequence Y to obtain a second change sequence Y';

[0019] Step S204: Obtain n change functions from the second change sequence Y' in order of arrangement to obtain a sampling sequence LY, LY: y1, y2, y3, ..., yn, where y1, y2, y3, ... and yn represent the first, second, third, ... and nth change functions in the sampling sequence LY, respectively, and obtain the function means of the first, second, third, ... and nth change functions, respectively, and record them as yc1, yc2, yc3, ... and yc n , satisfying the conditions:

[0020] yc1<yc2<yc3<……<yc n ;

[0021] The function saved in the sampling sequence describes the regular relationship between the actual operation data of the operation data item and the time change. Since the units of different operation data items are different, the change relationship cannot be directly compared. Therefore, the scheme adopts the method of converting the actual operation data of the operation data item into the load rate change method. The load rate is the ratio of the instantaneous load of the operation data phase to the maximum load. The instantaneous load is the instantaneous actual operation data.

[0022] In order to prevent the load rate average value from affecting the value of the comparison function due to the existence of 100% and 0%, it is necessary to screen the functions in the variation function sequence Y and remove the functions with the largest and smallest mean values, so as to stably remove the load rate average value from existing in the two cases of 100% and 0%.

[0023] Step S205: Establish a comparison function H, Adjust the change function in the second change sequence Y', calculate the calculation results of H respectively, traverse the calculation results of H, and obtain the second change sequence Y' when the calculation result of H is the largest, which is recorded as the target sampling sequence;

[0024] H represents the relationship between the load rate average value and the load difference. The purpose of step S205 is to select the function relationship corresponding to the n operation data items with the largest sum of differences. The operation changes of the selected operation data items represent the characteristics of the target device.

[0025] Step S206: obtaining operation data items corresponding to each variation function in the target sampling sequence, recorded as characteristic operation data items, and the characteristic operation data items correspond to the operation modes of the target devices.

[0026] Furthermore, step S300 includes:

[0027] Step S301: obtaining a target sampling sequence and function means corresponding to each variation function in the target sampling sequence, summing the function means, and obtaining a quantitative reference value D;

[0028] Step S302: Obtain the function mean dk corresponding to the k-th variation function in the target sampling sequence, and calculate the weight coefficient αk corresponding to the k-th variation function, αk=dk / D;

[0029] The weight coefficient represents the relative change characteristics between the operation changes of the selected operation data items. The weighted operation is performed on the function through the weight value, and the function characteristics after the weighted operation are compared, which is the basis for judging whether the comparison equipment is in a safe state in this scheme;

[0030] Step S303: Calculate the reference function W, W = α1×r1+α2×r2+α2×r2+…+αm×rm, where r1, r2, r3, … and rm represent the first, second, third, … and m-th change functions in the target sampling sequence, respectively, and α1, α2, α3, … and αm represent the weight coefficients corresponding to the first, second, third, … and m-th change functions, respectively;

[0031] The reference function represents the superposition relationship of individual changing functions, where W is the function, r1, r2, r3, ... and rm are functions, and α1, α2, α3, ... and αm are weight coefficients.

[0032] Furthermore, step S500 includes:

[0033] Step S501: obtaining the time point t0 when the target device receives the instruction information, and submitting the operation record of the target operation data item of the target device in the time period T after t0 or the time period T before t0;

[0034] Step S502: plotting the load rate variation function of each operation data item of the target operation data item with respect to time, and obtaining a variation function sequence L1, L1: f1, f2, f3, ..., fe, wherein f1, f2, f3, ... and fe represent the variation functions corresponding to the first, second, third, ... and e-th target operation data items, respectively;

[0035] Step S503: Obtain the operation data items corresponding to each change function in L1, match the weight coefficients in the feature database according to the operation data items, collect the weight coefficients of each change function, and obtain the target weight sequence Q, Q: β1, β2, β3, ..., βe, where β1, β2, β3, ... and βe represent the weight coefficients corresponding to the first, second, third, ... and e-th change functions respectively;

[0036] Step S504: Calculate the objective function G, G = β1×f1+β2×f2+β3×f3+…+βe×fe;

[0037] By obtaining the weight coefficient and multiplying it with the function, the function characteristics can be further amplified to verify whether the change law of the function corresponding to the target setting operating parameter item is consistent with the change law under the safe state.

[0038] Furthermore, step S600 includes:

[0039] Step S601: the reference function corresponding to the current operation mode of the target device is recorded as WG, and the similarity between WG and G is calculated and recorded as simg;

[0040] Step S602: Obtain a similarity judgment threshold γ. When simg<γ, it is determined that there is a difference between the target function and the reference function.
