Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. The following description of at least one exemplary embodiment is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The embodiment provides a method for quickly judging interval delay samples of fused edge calculation, and the method for quickly selecting the interval delay samples of the fused edge calculation is already in a trial stage and is described below with reference to fig. 1-2.
Fig. 1 is a flowchart of some embodiments of a method for fast determining a section delay sample of fused edge computation according to the present invention, where the method includes seven steps.
In a first step, interval samples of sensitive applications are obtained.
Specifically, the interval samples are delay data under the delay condition of the sensitive application, that is, data values of delay time length of the screened sensitive application in the same period, for example, delay time length, response time length and the like. One or more of the delay data can be acquired, and after the delay data is acquired, a section sample is formed, wherein the acquisition object is a data value of any time period of the delay section, sequential acquisition is not performed, and the rapidness of the method is improved through randomness.
In the second step, after the interval sample is obtained, randomly screening the sample values at the moments t, t+1, … and t+n from the obtained interval sample, and marking the sample values as corresponding、/>、/>、…、/>Wherein the indices 0, 1, …, n correspond to t, t+1, …, t+n.
In other words, the obtained section samples are randomly screened, for example, the section sample time period is from 8 th second to 15 th second when the event occurs, then a starting point moment is randomly screened from the section samples, for example, the starting point moment can be screened from 9 th second, then 10 th second, 11 th second, 12 th second and the like are respectively selected, and the corresponding selection is specifically performed according to the actual judgment requirement, wherein the screening adopts a random numerical value screening method.
Then, after the time samples related to the time are selected, the delay data corresponding to the time samples are marked, in other words, the sample value is the delay time length data of the corresponding time. The time delay duration data is adopted、/>、/>、…、/>The marking is only one marking symbol, has no practical operational significance, and aims to facilitate the follow-up work of the inventor. In some embodiments, the marker may have a computational meaning, and may need to be obtained through actual calculation, but the marker is obtained anyway, and is a sample value of a time sample under the knowledge of those skilled in the art.
In the third step, according to the obtained sample value, the extremum ratio of the sample value is calculated, and the calculation formula is as follows:
wherein a is t, t+1, …, t+n;a is a sample value at the corresponding time of a; />Is the extremum ratio of the sample values.
Wherein, the calculation formula is as follows: two adjacent sample values are selected for comparison. For example, sample values of 8 th and 9 th seconds are selected for comparison, and then substituted into the above formula: the denominator is the sample value of 9 seconds, the numerator is the sample value of 8 seconds, and the extremum ratio is 0.5 assuming that the sample value of 8 seconds is-3 ms/s and the sample value of 9 seconds is-6 ms/s.
In the fourth step, the time-lapse sample acquisition qualification rate is judged based on the extremum ratio of the sample values. Specifically, when the sample value extremum ratioIf the time delay sample is not less than 0.05, the time delay sample is unqualified, the section sample is required to be deleted, and the section sample is re-acquired after the deletion; when the extreme value ratio of the sample value-><And 0.05 time, the delay sample is qualified.
In other words, when the extremum ratio is greater than or equal to 0.05, the delay condition between the adjacent moments is serious, the final application effect damage to the sensitive application can occur, at this time, the section samples need to be processed, the related program is removed or the related program content is modified, the delay effect is perfected, otherwise, when the extremum ratio is less than 0.05, the delay is in a qualified state, and the delay can not affect the sensitive application. The sensitive application of the invention is matched application used by the military industry and the precision instrument, so the data delay has the requirement of quick response, the requirement is more biased to the range of the first time for quickly judging the false occurrence position of the problem, the accurate judgment of the position point is not required, and the double operation of the position point and the repair can be carried out after the range of the interval is judged, so the invention is only carried out for the first judgment, namely the operation of the first time.
Meanwhile, the numerical point with the 0.05 extremum ratio is an empirical value of daily operation obtained by the inventor under the working condition, and the numerical point can be understood as meeting the range of the numerical point, namely the certain delay data is qualified data, and is not unqualified data.
In the fifth step, the adjacent sample values corresponding to the qualified acquisition rate in the delay samples are accumulated and summed, and the accumulated and summed result is usedAnd (c) represents the number of accumulated sums, where m represents the number of accumulated sums and m=1, 2, 3, … n. Specifically, after knowing the value of the interval sample obtained by qualification, the qualified interval sample is summed, when +.>When the value is less than 0.05, accumulating and summing adjacent sample values corresponding to the qualified acquisition rate in the delay sample, wherein the steps are as follows:
…
it will be understood that when the qualified time sample value is 9 th second, 10 th second, 11 th second, the sample values of the three times are accumulated and summed to obtain a new data, for example, the data value corresponding to 9 th second is-1 ms/s, the data value corresponding to 10 th second is-2 ms/s, the data value corresponding to 11 th second is-3 ms/s, and the accumulated and summed value is-6 ms/s, so that the value is obtained and then further judged in the subsequent steps.
In the sixth stepFor each accumulated sum resultAnd (5) performing subtraction operation with the value 0 to judge the delay sample. Sum result for each accumulation +.>Performing subtraction operation with the value 0, and when the subtraction value is smaller than 1, representing that the interval sample delay is qualified; otherwise, when the numerical difference is larger than 1, the representative interval sample delay is unqualified, and the interval delay exists.
Specifically, -6ms/s is subtracted from 0 to obtain-6 ms/s, and the value is necessarily smaller than 1, so that the interval sample delay is qualified, and if the value is subtracted from 0 to obtain 6ms/s in a reasonable delay range, the value is larger than 1, and the value is unqualified. The above-mentioned accumulation operation is similarly performed when the judgment is performed by combining the negative sign before the number. When the value is larger than 1, the first judgment meets the requirement of the extremum ratio of 0.05, but the further verification is problematic, and the interval sample is proved not to be in a reasonable or qualified delay interval, so that the realization process of the corresponding application program still needs to be repaired and perfected.
In the seventh step, the above process needs to be circulated until the delay sample is determined, and the delay sample is a qualified sample and a disqualified sample, so as to perform the subsequent determination operation.
In order that the method of the invention may be more widely applicable while providing a higher understanding of the method of the invention, the invention also provides a system comprising an acquisition module for acquiring interval samples of sensitive applications; the screening module is used for randomly screening sample values at times t, t+1, … and t+n from the acquired interval samples and marking the sample values correspondingly; the first operation module is used for calculating the extremum ratio of the sample value and judging the time-delay sample acquisition qualification rate based on the extremum ratio of the sample value; the second operation module is used for accumulating and summing adjacent sample values corresponding to the qualified acquisition rate in the delay samples; the third operation module is used for subtracting the value 0 from the accumulated sum result of each time; the judging module is used for circulating the above processes until the delay sample is obtained.

In some embodiments, the first computing module is in data communication with the second computing module, the second computing module is in data communication with the third computing module, and the other end of the judging module is in data communication with the third computing module.
