[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Example 1:

[0029] This embodiment provides a random number generator, including a chaotic pendulum 1, a parameter measuring element, a parameter receiving element, and a signal processing element 2; the parameter measuring element is fixed to the swinging end of the chaotic pendulum 1 in a chaotic motion state, and is used to measure the motion state information value of the swinging end. The motion state information may include but is not limited to the linear velocity, angular velocity, acceleration, position information, etc. of the swinging end; the parameter receiving element communicates with the parameter measuring element and is used to receive data information measured by the parameter measuring element; the signal processing element 2 is communicatively connected to the parameter receiving element and is used to output random data based on the data information measured by the parameter receiving element.

[0030] Therefore, this embodiment measures the motion state information of the swing end in a chaotic motion state on the chaotic pendulum 1 whose trajectory cannot be predicted, and processes the motion state information value to obtain random data, thereby obtaining truly random data, avoiding the possibility of data being predicted, and ensuring information security; moreover, the random number generator in this embodiment also has the advantages of low production, operation and maintenance costs, and easy data acquisition.

[0031] The present invention can adopt any form of chaotic pendulum 1, which can have one main pendulum and two or three auxiliary pendulums. Figure 1 As shown, in this embodiment, the chaotic pendulum 1 is a double-rod chaotic pendulum 1, comprising a bracket 13, a first operating rod 11, and a second operating rod 12. The middle portion of the first operating rod 11 is hinged to the bracket 13, one end of the first operating rod 11 is hinged to the middle portion of the second operating rod 12, and a parameter measuring element is fixed to the other end of the first operating rod 11. The length of the first operating rod 11 is greater than that of the second operating rod 12. In this embodiment, the parameter measuring element is a velocity sensor 14, which is used to measure the linear velocity of the end of the first operating rod 11. Bearings can be provided at the hinged locations of the first operating rod 11 and the bracket 13, as well as at the hinged locations of the first operating rod 11 and the second operating rod 12.

[0032] In this embodiment, the signal processing element 2 is used to obtain linear velocity values ​​corresponding to a plurality of consecutive evenly spaced moments, and to take the units digit of the plurality of linear velocity values ​​as a final random number, thereby generating a plurality of random numbers. The interval for obtaining the values ​​can be 1 second or 1ms to 10ms, and the number of values ​​can be selected according to actual needs.

[0033] In this embodiment, the chaotic pendulum 1 further includes a base 15 , and the bracket 13 is fixed on the base 15 .

[0034] In this embodiment, the chaotic pendulum 1 has an electric drive mechanism to ensure that the chaotic pendulum 1 can continue to perform chaotic motion. The electric drive mechanism in the chaotic pendulum 1 is well known to those skilled in the art. It usually uses electromagnetic pulse drive to drive the first operating rod 11 to overcome bearing friction and air resistance.

[0035] Example 2:

[0036] This embodiment provides a method for obtaining a random number, using the random number generator in Embodiment 1, including the following steps:

[0037] S1. The central control system receives an instruction from the demand side to obtain a random number;

[0038] S2, the central control system instructs the parameter measurement unit to measure the linear velocity values ​​of the swing end of the chaotic pendulum 1 corresponding to a plurality of consecutive evenly spaced moments, and transmits the linear velocity values ​​to the signal processing unit through the signal receiving unit, and takes the units digit of the plurality of linear velocity values ​​as the final random number, thereby finally generating a plurality of random numbers;

[0039] S3. The central control system sends the generated random number to the demand side.

[0040] In this embodiment S2, if the chaotic pendulum 1 is initially in a stationary state, the electric drive mechanism drives the chaotic pendulum 1 to start moving. After the chaotic pendulum 1 reaches the chaotic motion state, the parameter measurement unit measures and obtains the linear velocity value of the swing end of the chaotic pendulum 1.

[0041] In this embodiment S2, the number of linear velocity values ​​measured by the parameter measurement unit is 6.

[0042] In this embodiment S2, the time interval for obtaining multiple linear velocity values ​​is 1 second.

[0043] In a specific example, if you need to obtain a random password for online banking or a mobile phone verification code required to log in to other websites, you can set up a random number generator in the remote background to generate a random number, and use the random number as the mobile phone verification code to send to the user's mobile phone.

[0044] For example, a speed sensor 14 is installed at the end point of the long section of the long rod on the chaotic pendulum 1. When the chaotic pendulum 1 moves, the rate is collected every 1 second, and a total of 6 times. The detected rate is used as a random number and wirelessly sent to the parameter receiving element. The parameter receiving element then transmits the signal value to the signal processing element 2. The signal processing element 2 takes the unit digit of the random rate value as the final random number, and finally generates 6 random numbers.

[0045] The measured data are shown in the following table.

[0046] Time(s) 1 2 3 4 5 6 Speed ​​(m / s) 15 29 8 6 11 2 Signal processing element processing value 5 9 8 6 1 2

[0047] The random number obtained is 598612.

[0048] Adaptive changes based on actual needs are all within the scope of protection of the present invention.

[0049] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
