13.0 degrees Celsius of temperature of office；13.9 degrees Celsius of Hunan Meteorological Bureau of Shanxi Province temperature.
Step 2-2, the data of acquisition are kept in.
Step 2-3, to temporary data, ten, hundred, thousand or ten thousand undulating value of each data bit calculate.
In the present embodiment, tens is respectively：1st, 1,1,1,1,1, units is respectively：3rd, 3,3,3,4,4, decimal point
Latter position is respectively：0、1、5、6、8、9.Variance be each data respectively and the difference of its average square and average.
Formula is：Wherein, x represents the average of sample, n
Represent the quantity of sample, xiRepresent individual, and s2Variance is meant that, by being calculated：Tens variance is 0, units variance
For 0.148, one decimal place variance：11.375.
Step 2-4, data of the undulating value in data temporary storage location 13 less than 5 are deleted according to undulating value.
In the present embodiment, the one decimal place for the data average that variance is 11.375 is taken, other data are deleted.
If having multiple variances more than 5, take variance it is maximum for valid data.
Step 3, source data is combined according to rule of combination set in advance, number can be tested at random so as to obtain.
In the present embodiment, the one decimal place for the data average that variance is 11.375 is taken, average is
4.833333 it is 8 to obtain random number.Other data splittings weigh the first step and started again.
Rule of combination is the evolution of the sum of the data bit of the data captured, data bit is the average of odd number, data bit
It is that the average of even number or data bit number remove two remainders, the rule that other logarithm values can also be used to be calculated and combined.
The effect of embodiment and effect
The acquisition of the present embodiment can test several devices and methods therefors at random because can test at random number be can be inquired about from the public,
The source data that the data platform that individual can not manipulate obtains, so ensure that randomness.Because used fluctuation computing unit
The undulating value of each data bit of data can be calculated and used fluctuation data screening unit can be to fluctuation
Value is screened, so it is single to avoid source data.Because the data combination section having can be entered to data using combination
Row combination, so that the scope for ultimately generating random number is wider, randomness is stronger..Therefore, acquisition of the invention can test at random
Several devices and methods therefors make it that winning results is more fair, just interests that can ensure lottery fan.
Above-mentioned embodiment is the preferred case of the present invention, is not intended to limit protection scope of the present invention.
