Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, fig. 1 is a schematic overall structure diagram of an embodiment of the present invention.

In one embodiment of the present invention, the random number generator based on mechanical structure mainly comprises a base 1, a rotating member 2, a driving member 3, a detector 4 and a random number generator 5.

Wherein, base 1 is the major structure, mainly used installs other spare parts.

The rotary member 2 is provided on the base 1 and can perform a rotary motion on the base 1.

The driving part 3 is arranged on the base 1 and can perform directional reciprocating motion on the base 1, and is mainly used for driving the rotating part 2 to perform intermittent rotation, namely discontinuous rotation, in the motion process, and specifically, the driving part 3 drives the rotating part 2 to complete one directional rotating motion in the one reciprocating motion process.

The detector 4 is arranged on the base 1, and is mainly used for detecting the rotation state of the rotating member 2 and generating a corresponding electrical parameter according to the rotation stop angle of the rotating member 2 after the single directional rotation motion is finished.

The random number generator 5 is in signal connection with the detector 4 and is mainly used for converting the electrical quantity generated by the detector 4 into a corresponding digital signal, thereby generating a numerical value.

Thus, due to the non-ideal characteristics of the mechanical structure in reality, such as the friction effect of the rotating member 2 during rotation, the deviation of the motion state of the driving member 3 during each reciprocating motion, the deviation of the driving state of the driving member 3 to the rotating member 2, the subsequent deviation of the elastic force of the spring 33, the deviation of the stroke of the moving rod 31, the deviation of the collision angle between the convex teeth 32 and the gear teeth, etc., the rotation angle of the rotating member 2 after being driven to rotate to stop by the driving member 3 each time is slightly different, so that a random angle value is formed within a certain range, the detector 4 generates different electrical parameters according to the different rotation angles of the rotating member 2 after each rotation stop, and then converts the electrical parameters into digital signals through the random number generator 5 to output random numbers.

Compared with the prior art, the random number generating device based on the mechanical structure provided by the embodiment utilizes the non-ideal characteristic of the mechanical structure to enable the rotating member 2 to generate random motion parameter changes in each rotating process, so that the random number can be conveniently and easily generated, and the production cost and the energy consumption are reduced.

In a preferred embodiment with respect to the rotary member 2, the rotary member 2 is embodied as a flywheel or a gear. Meanwhile, the rotating member 2 is connected with a rotating shaft, and the detector 4 is mainly used for detecting the rotating state of the rotating shaft of the rotating member 2 so as to accurately judge the rotating angle of the rotating member 2 after the single rotation is stopped. Of course, the detector 4 may directly detect the rotation state of the rotary member 2 itself.

As shown in fig. 3, fig. 3 is a schematic view of a connection structure of the rotating member 2 and the detector 4.

Further, in order to improve the detection accuracy of the detector 4, in the present embodiment, the rotary member 2 is specifically attached to the detector 4, and the rotation shaft of the rotary member 2 is inserted into the housing of the detector 4 and maintains the rotational degree of freedom. With this arrangement, the rotating shaft of the rotating member 2 can rotate in the housing of the detector 4, and the proximity detection can be performed by a relevant sensor in the housing of the detector 4, such as a photoelectric sensor, a displacement sensor, an image sensor, and the like.

In a preferred embodiment with respect to the detector 4, the detector 4 is embodied as a potentiometer in order to facilitate the generation of a corresponding electrical quantity depending on the detected angle of rotation of the rotary member 2. The potentiometer is an adjustable electronic element, has an action principle similar to that of a sliding rheostat, and can adjust the specific wiring position of a built-in circuit according to the change of the rotation angle of the rotating piece 2, so that a corresponding component generates sensitive resistance value change or voltage value change.

In a preferred embodiment with respect to the driving member 3, the driving member 3 mainly comprises a movement rod 31 and a cam 32. Wherein the motion bar 31 can perform a linear reciprocating motion on the base 1 and is located at a position of one side of the rotation member 2. Generally, the linear motion direction of the motion bar 31 is kept in line with the length direction thereof, and the end of the motion bar 31 is usually driven by a micro motor. The convex teeth 32 are arranged on the rod body of the motion rod 31, protrude out of the side wall of the rod body of the motion rod 31 by a certain height, and are mainly used for abutting collision with the gear teeth on the rotating part 2 in the single-pass motion process of the motion rod 31 so as to form a rotating moment on the rotating part 2 through abutting acting force and drive the rotating part 2 to perform single directional rotation.

Fig. 2 is a schematic view of the state in which the moving rod 31 is at the maximum stroke for one trip, as shown in fig. 2.

Further, considering that the motion rod 31 needs to perform a linear reciprocating motion to drive the rotating member 2 to rotate during each motion, in order to facilitate the automatic return of the motion rod 31, a spring 33 is added to the driving member 3 in this embodiment. Specifically, one end of the spring 33 is connected to the base 1, and the other end is connected to the rod body of the moving rod 31, and the elastic expansion and contraction direction of the spring 33 is parallel to the moving direction of the moving rod 31. So configured, when the motion bar 31 reaches the limit position in a single movement (right movement as shown), the spring 33 will be stretched (or compressed) to the limit, and then automatically return to the initial position under the action of the elastic force.

Generally, considering that the teeth 32 provided on the moving rod 31 need to make abutting collision with the teeth on the rotary member 2, the surface of the teeth 32 may be provided with smoothly transiting wedge teeth, so as to slightly and slowly collide with the teeth on the rotary member 2 during the forward stroke of the moving rod 31, and further slightly rotate the rotary member 2 clockwise, and then rapidly and heavily collide with the teeth on the rotary member 2 under the elastic force of the spring 33 during the backward stroke, and further rotate the rotary member 2 counterclockwise by a large angle, and the detection data of the detector 4 only needs to record the rotation angle of the rotary member 2 during the backward stroke of the moving rod 31.

Further, in order to facilitate the connection of the spring 33 to the moving rod 31, the connecting table 34 is provided on the rod body of the moving rod 31 in this embodiment. Specifically, the connecting portion 34 protrudes from the surface of the motion bar 31, and is generally located on two opposite sides of the motion bar 31 with the protruding teeth 32. With this arrangement, the other end of the spring 33 can be connected to the wall surface of the connecting table 34, and the extending direction of the spring 33 is ensured to be parallel to the moving direction of the moving rod 31.

In addition, in order to ensure the stability of the moving rod 31 during the linear reciprocating motion, the present embodiment is further provided with a guide rail 6 on the base 1. Specifically, the length direction of the guide slide rail 6 is collinear with the length direction of the moving rod 31, and the end of the moving rod 31 is inserted into the guide slide rail 6, so that the guide slide rail 6 is used for providing a guiding effect for the linear motion of the moving rod 31, and the linear motion of the moving rod 31 is prevented from shaking or vibrating during the motion process.

Moreover, considering that the amount of the expansion deformation of the spring 33 is not too large when the moving rod 31 moves, otherwise the impact force between the protruding teeth 32 and the rotating member 2 is too large due to too large elastic force, which may cause damage, the embodiment further includes a limiting block 7 on the base 1. Specifically, the stopper 7 is located on one side of the moving rod 31 in the single-stroke moving direction, and is mainly used for abutting against a connecting table 34 provided on the moving rod 31 to limit the maximum stroke of the moving rod 31 in the single stroke, and at the same time, to limit the maximum deformation amount of the spring 33.

As shown in fig. 4, fig. 4 is a schematic diagram of a circuit structure of the random number generator 5.

In a preferred embodiment with respect to the random number generator 5, the random number generator 5 mainly includes an ADC module 51 and a value generation module 52. The ADC (Analog to digital converter) module 51 is in signal connection with the detector 4, and is mainly used for converting an electrical parameter (Analog quantity) generated by the detector 4 into a digital quantity. The numerical value generating module 52 is in signal connection with the ADC module 51, and is mainly configured to generate a numerical value, i.e., a random number, according to the digital quantity generated by the ADC module 51. Generally, the value generation module 52 may be an FPGA (Field Programmable Gate Array). For example, the FPGA may obtain a 31-bit 2-ary number or a 10-bit decimal number as a random number through the 31-bit ADC module 51.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
