When the system draws a lottery, a user selects a lottery number through the lottery module to participate in the lottery, and the lottery module submits a lottery request to the lottery request queue of the lottery request monitoring module; when the lottery request monitoring module monitors that a lottery request exists in the lottery queue, the lottery request monitoring module submits the lottery request to the lottery number generating module, and the lottery number generating module starts a lottery program; the lottery number generation module sets the type of the lottery numbers according to the lottery probability and generates a lottery number original table; the prize-winning number generation module scrambles the original table of the lottery numbers by shuffling algorithm to generate a random ranking table of the lottery numbers; the winning number generation module generates true random lottery interval seeds through real-time state data of computer hardware, and generates lottery interval sequences with true random attributes according to the true random interval seeds; the lottery number generation module extracts lottery numbers from the lottery number random sorting table according to the generated lottery interval sequence, generates a lottery number sequence and returns the lottery number sequence to the lottery request monitoring module; the lottery drawing request monitoring module determines whether the user wins a prize according to the winning number sequence and returns a winning result to the lottery drawing module; and the lottery module informs the user whether the user wins the prize according to the winning result and publishes the winning result. The winning numbers generated by the lottery through the system have the properties of uniform distribution, unpredictability and non-periodicity. The invention directly produces the random number only according to the inherent functions of the computer, has low production cost and high efficiency, and can be used for generating mass random numbers for online real-time lottery.

1. The complete technical scheme (invention scheme) provided by the invention is as follows:

(1) user selects lottery drawing number to participate in lottery drawing

The user selects to participate in the lottery in a certain period through the system lottery module, the number of the lottery is selected, the number of the selectable lottery is all kinds of numbers in the lottery number original table, the lottery module submits a lottery request to the lottery request monitoring module, and the lottery request enters the lottery request queue of the lottery request monitoring module.

(2) Lottery program initiation

When the lottery system monitors that lottery requests exist in the lottery queue, the lottery requests are submitted to the lottery number generating module for all the lottery requests, and the lottery number generating module starts a lottery program after receiving the requests to extract the lottery numbers for all the lottery requests.

(3) Lottery drawing number original table generation

1) The lottery numbers and the number of each number in the lottery number original table are set according to the probability of winning. For example, lottery numbers may be set to 0, 1, and the number of each number may be set to ten thousand, one hundred thousand, one million, etc., to form an original table of lottery numbers of different levels. The lottery numbers contained in each of the original tables of lottery numbers may also be adjusted. The lowest number can be set as 2, and the highest number can be set as the same number as the numbers of the lottery number original table. If the number of numbers in the lottery number original table is set to 100 ten thousand: when the types of the lottery numbers are 2, the number of each lottery number is set to be 50 ten thousand, and the occurrence probability of each random number is one half; when the types of the lottery numbers are 10, the number of each lottery number is set to be 10 ten thousands, and the occurrence probability of each lottery number is one tenth; when the maximum number of types of lottery numbers is set to 100 ten thousand, the number of each type of winning number is set to 1, and the probability of occurrence of each type of random number is one millionth. The probability of occurrence of each kind of lottery numbers decreases correspondingly when the kind of lottery numbers increases one by one. Further, the larger the number of lottery numbers in the lottery number original table, the larger the short-term winning probability deviation ratio of the lottery numbers.

2) The probability of winning for each lottery number may be set equal or close, and may be adjusted as desired. If the lottery numbers are 2 types (1 and 2), the length of the array is 1 ten thousand: assuming that the winning probability is set equal for each lottery number, 5000 for 1 and 5000 for 2 can be set; 4900 for 1 and 5100 for 2 can be set under unequal conditions, and the setting can be customized according to different requirements. Under the condition of equality, if the number of the lottery numbers is divided by the types of the lottery numbers, the number of the lottery numbers which is not divided is removed, for example, the number of the lottery numbers is 3 (1, 2 and 3), each number of the lottery numbers is 3333, the total number of the numbers of the original table of the lottery numbers is 9999, and 1 number of the mantissas is removed. And so on.

3) The winning number generation module automatically generates N winning numbers according to the setting conditions of the winning probability of the winning numbers and the winning probability of different numbers, the number of N is generally set to be 100 ten thousand, under the condition that the winning probabilities of different numbers are different, the winning number generation module needs to regularly and automatically adjust the number of different numbers, so that the winning probability of each kind of the winning numbers is uniformly fluctuated up and down, the average probability of each kind of the winning numbers is equal, and the adjustment period can be set to be 1 day or 1 week.

(4) Lottery number random ordering table generation

1) The lottery drawing number sorting table is formed by different permutation and combination changes of all lottery drawing numbers in the lottery drawing number original table.

2) The number of different winning number sorting tables that can be generated by the lottery number original table is determined by the number of winning numbers and the kind of winning numbers of the lottery number original table. The most winning number ranking tables can be generated when the number of types of winning numbers is equal to the number of winning numbers in the original table of winning numbers, in which case the total number of different random winning number ranking tables is a factorial in the length of the array. The minimum number of winning number ranking tables that can be generated when there are only 2 random number categories is, in this case, the total number of different random winning number ranking tables is (the factorial of array length) divided by (the factorial of half array length).

3) The winning number generation module randomly shuffles the number order in the original table of lottery numbers by a shuffling algorithm (e.g., Fisher-Yates Shuffle algorithm) to generate a random ranking table of lottery numbers.

(5) True random lottery interval seed generation based on computer hardware state data

The winning number generation module utilizes the computer system function to obtain the computer time, the CPU utilization rate and the memory utilization rate to form a character sequence, the character sequence is totally composed of 51 digits, the first 17 digits are computer time data, the first 18 to 34 digits are computer CPU utilization rate percentage data, the second 35 to 51 digits are computer memory utilization rate percentage data, the sequence is randomly disordered by using a shuffling algorithm, then the data is converted into 16 hexadecimal by using MD5, and then the data is converted into decimal digits, and the decimal digits are true random seeds of the lottery interval.

(6) Lottery interval sequence generation

1) The lottery number generation module generates a sequence of lottery intervals having a length equal to the number of lottery requests using the true random seed for the lottery intervals.

2) And when the lottery interval true random seed number is N, and the lottery request number is M, the lottery number generation module generates M positive integer random numbers between 1 and N by using a pseudo-random algorithm, wherein each random number represents the position of the lottery interval true random seed, and the numbers of the corresponding positions in the lottery interval true random seeds are sequentially copied according to the M random numbers to form a M-number true random interval number sequence.

3) Each digit in the sequence of drawing intervals represents the interval between two adjacent drawing positions when drawing a winning number. For example, the number 2 represents that the currently extracted number position is separated from the previously extracted number position by 2 numbers.

(7) Winning number sequence generation

1) The winning number generation module extracts winning numbers from the random lottery number ranking table for each lottery request in turn according to the interval number sequence to form a winning number code sequence,

2) if the lottery numbers are only 0 and 1, the number sequence in the sorting table is 1, 0, 1, 1, 0, 1, 0, 1, 0, 1, 1, 0. The drawing interval sequence is 1, 3, 2, 1. The winning number is the 2 nd, 6 th, 9 th, 11 th digit number, i.e., the winning number sequence is 0, 1, 0, 1.

3) And after the winning number generating module generates a winning number sequence, the result is returned to the lottery drawing request monitoring module.

(8) Determining winning results

The lottery request monitoring module determines the winning number of each lottery request according to the winning number sequence, determines whether the user wins according to the winning number, and returns the result to the user lottery module. And the user lottery module informs the user whether the user wins the prize according to the winning result and publishes the winning result.

(9) The winning number produced by the method has the characteristics

The winning number produced by the method has the following characteristics: uniform distribution, unpredictability, aperiodic.

1) Uniformity of distribution

The number of each number in the lottery drawing number original table has uniformity, and the lottery drawing numbers in the lottery drawing number sorting table produced by using the lottery drawing number original table have uniform distribution. Drawing from a lottery number sorting table with uniform distribution property according to the hardware state data of the true random calculator, wherein the sequence formed by the drawing result has the same uniform distribution property. Whether the true random numbers themselves have uniform distribution does not affect the uniform distribution of the extraction results.

2) Unpredictability

Because there is no inevitable logic relation based on algorithm between the winning numbers produced by the method, the drawing position of the winning numbers is related to the real-time computer hardware state data and can not be predicted before drawing, therefore, the winning numbers produced by the method are the same as any true random numbers and can not be predicted.

3) Aperiodic

From the structure set by the original table of lottery numbers, different array lengths, different random number types and array proportions of the random number types and the array are changed, any variable of the original table of the lottery numbers can generate a different original table of the lottery numbers, and each original table of the lottery numbers can generate different astronomical-grade permutation and combination, so that the number of the random permutation tables of the lottery numbers tends to be infinite and has non-periodicity. Real random data of computer hardware state that changes instantly has natural physical objective properties that are aperiodic. The computer hardware state true random data is superimposed with the lottery number random sort list to produce winning numbers which are non-periodic.

2. The technical scheme of the invention has the following beneficial effects:

the invention solves the problems of true randomness and safety of online real-time lottery drawing, generates uniformly distributed random winning numbers with low cost and high efficiency, and provides an effective technical solution for online infinite convenient production and supply of true random numbers for timely large-scale lottery drawing. The production method can be used for conveniently and effectively producing the true random number on any common computer without adding and modifying any function, and compared with other lottery drawing methods, the method has strong economic advantages of low cost in production, management and use.
