Specifically, the core of the above-mentioned calculation logic is that the sequence consistency detection, through comparing the time stamp of each operation step, calculate the deviation of each step relative to the expected sequence, get the sequence consistency deviation, reflect the time difference between user's operation and predefined operation sequence, thus help to evaluate the accuracy of the operation, especially for the operation flow needing to go on strictly in order, the calculation logic measures the order problem of the operation accurately by combining the time difference detection function, time offset function and accumulation of the sequence deviation; using corrected time stampsThe time difference and time offset of adjacent operational steps are calculated. Specifically, the time difference detection function in the formulaMeasuring the difference between the time interval between two adjacent steps and the expected interval, and integrating the termReflecting the cumulative effect of system load and delay fluctuations on time stamps between steps, the firstWeighting factors for individual operating stepsThe method is used for representing the importance of each step, different steps can have different weights, the value range is a positive real number, and the value is set according to the importance degree of the operation step; by detecting the time deviation of each operation step, the system can accurately evaluate whether the operation of the user accords with a predefined sequence, and the final evaluation result is prevented from being influenced due to the problem of the operation sequence; meanwhile, the sequence of the operation can be detected in real time, and once the overlarge time difference between the operation steps is found, the feedback and correction can be timely carried out, so that the accuracy and efficiency of the operation are improved.
The invention further provides that the calculation logic of the operation step matching error is as follows: Wherein, the method comprises the steps of, wherein, In order for the operational steps to match the errors,In order to achieve the number of operating steps,Is the firstThe weight factors of the individual operating steps,Is the firstThe method comprises the following operation stepsAnd the firstA plurality of predefined operation stepsIf the matching function of (3)And (3) withComplete match, thenOtherwise, 0; in particular, the above-described calculation logic is directed to calculating the operation step match errorI.e. the degree of difference between the actual operating step and the predefined operating step. By introducing matching functionsAnd weight factorThe system can gradually calculate the matching condition of each operation step, and obtain the matching error of the whole operation sequence according to the accumulation of the matching error, so as to effectively evaluate the gap between the actual operation of the user and the standard operation flow and help the system to detect the deviation in the operation process; the operation step matching error is an error value obtained by comparing an operation step executed by a user with a predefined standard step, and represents the deviation degree between the user operation and the standard operation; matching functionFor judging user executionThe method comprises the following operation stepsWith predefined standard stepsWhether or not to match with each other, the firstWeighting factors for individual operating stepsThe critical steps are typically given a greater weight and the minor steps are given a lesser weight, depending on the relative importance setting of each operational step throughout the operational sequence; the value range is 0 to 1, and the value is flexibly adjusted according to the actual application scene; by gradually calculating the matching error of each operation step, the system can finely evaluate the deviation condition of the user operation and ensure the accuracy of the evaluation result.
The invention is further arranged that the calculation logic of the operation accuracy is: Wherein, the method comprises the steps of, wherein, For the accuracy of the operation,In order to achieve the number of operating steps,Is the firstThe weighting factors of the operating parameters of the individual operating steps,Is the firstOperating parameters of the individual operating stepsAnd the firstOperating parameters of a predefined operating stepIs calculated as:， And For the minimum and maximum values of the operating parameters of the predefined operating steps,For attenuation coefficients, for controlling the degree of matching when the parameters are out of range; specifically, the above-described computational logic aims at calculating the operational accuracyI.e. the accuracy with which the user controls the parameters during operation. By matching actual operating parametersAnd predefined standard parametersThe system may evaluate the accuracy of the parameters for each step and score according to the magnitude of the deviation. The whole calculation logic introduces a matching functionTo quantify the differences between the parameters and finally to obtain the accuracy of the overall operation by accumulating the accuracy errors of the individual stepsThe matching function is a function for evaluating the gap between the operating parameter and the predefined criteria. If the actual parameters areIn the expected range, the matching degree is 1; if not, punish the deviation by exponential function, the firstWeighting factors for operating parameters of individual operating stepsAccording to the importance setting of each operation step, the weight of the key step is larger, and the weight of the auxiliary step is smaller; the value range is 0 to 1, and the value is flexibly set according to specific requirements; by introducing a matching function and an accuracy calculation formula, the parameter control accuracy of user operation is automatically estimated, the subjectivity of manual estimation is reduced, the accuracy and efficiency of estimation are improved, the logic can be suitable for estimating various operation parameters, and particularly under the condition that a plurality of operation steps and a plurality of parameters exist at the same time, the system can flexibly adjust the weight and the matching degree, and the accuracy of comprehensive estimation is ensured;
the invention further provides that the calculation logic of the practical training operation score is as follows: Wherein, the method comprises the steps of, wherein, For the purpose of practical training operation scoring,In order to provide a sequence identity deviation,In order for the operational steps to match the errors,For the accuracy of the operation,、AndFor adjusting the coefficient, the method is used for controlling the influence intensity of sequence consistency deviation, operation step matching error and operation accuracy on practical training operation scoring; specifically, the objective of the above-mentioned calculation logic is to calculate the practical training operation score by integrating the sequence consistency deviation, the operation step matching error and the operation accuracy, and the scoring formula processes the influence of each deviation term on the total score by using a nonlinear combination and introducing a logarithmic function and an exponential decay function, so as to ensure that the influence of different deviations on the score can be flexibly adjusted, and the sequence consistency deviation is used for measuring whether the operation steps are executed according to a predefined time sequence. The method is a result of evaluating the deviation of the time sequence of the steps executed by the user and the expected sequence of the system by the system, wherein the larger the deviation is, the larger the step sequence problem of the user during operation is indicated; the operation step matching error measures the degree of matching between the operation step actually performed by the user and the predefined operation step. By accumulating the matching condition of each step, the total matching error of the operation steps is finally obtained, the nonlinear increase of the error value is improved through cubic operation, and the fact that the score is obviously influenced by larger deviation is ensured; the accuracy of the operation measures how precisely the user has controlled the parameter during operation, the smaller the deviation, the closer the user-controlled operating parameter is to the desired criteria. An exponential decay term is introduced into the formulaTo handle the error, ensuring that the overall score is less affected when the parameter control deviation is small; when the deviation is large, the score drops rapidly; adjustment coefficient、AndFor adjusting the impact weight of each bias term on the overall score. In different operation scenes, the importance of sequence consistency, step matching and operation accuracy may be different, so that the adjustment coefficients are introduced to control the influence intensity of each error item, the value range is 0 to 1, the specific value is adjusted according to the actual operation scene, and the scoring system can more flexibly process scoring problems in different operation scenes by introducing a logarithmic function and an exponential decay function, so that the scoring can accurately reflect the overall performance of the operation; by comprehensively considering sequence consistency deviation, step matching error and parameter accuracy, operation can be evaluated from multiple angles, and the limitation of single index scoring is avoided; by nonlinear processing in a scoring formula, especially cubic operation and exponential decay, the scoring result can be rapidly influenced by larger deviation, so that a scoring system can accurately reflect the problems in operation; by introducing a logarithmic function to ensure that the score is within a reasonable range, the score result is prevented from being too concentrated at one extreme (e.g., too high or too low), so that the evaluation is more refined and reasonable.
The invention is further configured to generate a prompt signal and suspend execution of the operation sequence when the sequence consistency deviation is greater than a preset consistency deviation threshold, calculate consistency deviation of executed operation steps, and sort the executed operation steps in descending order of the consistency deviation, wherein the calculation logic of the consistency deviation of the executed operation steps is as follows: Wherein, the method comprises the steps of, wherein, Is the firstThe consistency of the individual operating steps is biased,For the time difference detection function, the calculation logic is:， Is the first The operation steps and the firstExpected time differences for the individual operating steps; in particular, the logic described above describes a processing scheme after the sequence identity deviation exceeds a threshold. When detecting that the sequence consistency deviation of the user operation steps exceeds a preset threshold, generating a prompt signal and reducing the operation deviation by adjusting the execution sequence of the operation steps. By sequencing the deviations of the executed steps, the operation steps can be intelligently rearranged, so that the subsequent operation sequence is ensured to meet the predefined requirement as much as possible, and the deviations are reduced to the greatest extent; when the sequence consistency deviation exceeds a preset consistency deviation threshold, the system generates a signal to prompt a user to operate the system in the presence of serious deviation. At this time, the system may temporarily stop the current operation, wait for the user to adjust the order of operations or take further action, and at the same time, the system may calculate the sequence consistency deviation of the executed operation steps, rank the operations, adjust the operations in order of the deviation from large to small, and attempt to reduce the deviation by rearranging the order of operations; the calculation logic of the consistency deviation of the executed operation steps is single-step calculation logic of the logic of sequence consistency detection, the consistency deviation of each step is obtained, the executed operation steps are arranged according to the size of the deviation, the step with larger processing deviation is displayed, the step with deviation is displayed intuitively, the correction is convenient for a user, when the deviation of the operation steps exceeds a preset threshold value, the system can generate a signal in time to remind the user, and the deviation of the subsequent operation is reduced by readjusting the sequence of the operation steps. The mechanism improves the flexibility and adaptability of operation and can correct errors in operation in real time; through calculation and adjustment mechanisms of sequence consistency deviation, the sequence and time accuracy of the user operation flow are ensured. When the operation deviation exceeds the threshold value, the system can generate a prompt signal and can intelligently display the sequence of operation steps with consistency deviation, so that the steps with larger deviation are intuitively displayed.
