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. 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.

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

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

The base 1 is a main body structure and is mainly used for installing other parts.

The rotary member 2 is provided on the base 1, and is rotatably movable on the base 1.

The driving piece 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 piece 2 to perform intermittent rotation, namely discontinuous rotation, in particular to driving the rotating piece 2 to complete one directional rotation motion in one reciprocating motion process of the driving piece 3.

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 corresponding electric parameters according to the rotation stop angle of the rotating member 2 after the single directional rotation movement is finished.

The random number generator 5 is in signal connection with the detector 4 and is mainly used for converting the electrical parameters generated by the detector 4 into corresponding digital signals so as to generate numerical values.

In this way, due to non-ideal characteristics of the mechanical structure in reality, such as friction influence of the rotating member 2 during rotation, motion state deviation of the driving member 3 during each reciprocating motion, driving state deviation of the driving member 3 on the rotating member 2, elastic force deviation of the subsequent spring 33, travel deviation of the moving rod 31, collision angle deviation between the convex teeth 32 and the gear teeth, and the like, the rotating member 2 is slightly different from each other in rotation angle after the rotating member 3 is driven to rotate to stop, so that random angle values are formed in a certain range, different electric parameters are generated by the detector 4 according to different rotation angles after the rotating member 2 is rotated to stop each time, and then the electric parameters are converted into digital signals through the random number generator 5 to output random numbers.

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

In a preferred embodiment with respect to the rotating member 2, the rotating member 2 is in particular 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 single rotation is stopped. Of course, the detector 4 may directly detect the rotation state of the rotating member 2 itself.

As shown in fig. 3, fig. 3 is a schematic diagram of a connection structure between 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 the degree of freedom of rotation is maintained. So arranged, the shaft of the rotary member 2 can rotate within the housing of the detector 4 and be closely detected by a related sensor within the housing of the detector 4, such as a photoelectric sensor, a displacement sensor, an image sensor, or 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 parameter in dependence on the detected rotation angle of the rotating member 2. The potentiometer is an adjustable electronic element, the action principle is similar to that of a slide rheostat, and the specific wiring position of the built-in circuit can be adjusted according to the rotation angle change of the rotating piece 2, so that the corresponding element generates sensitive resistance value change or voltage value change.

In a preferred embodiment with respect to the driver 3, the driver 3 mainly comprises a movement bar 31 and a tooth 32. Wherein the moving rod 31 is linearly reciprocated on the base 1 and is located at one side of the rotary 2. Generally, the linear movement direction of the movement bar 31 is kept collinear with the longitudinal direction thereof, and the end of the movement bar 31 is generally 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 forming abutting collision with gear teeth on the rotating piece 2 in the single-way motion process of the motion rod 31 so as to form a rotating moment on the rotating piece 2 through abutting acting force and drive the rotating piece 2 to rotate in a single orientation.

As shown in fig. 2, fig. 2 is a schematic view of the movement bar 31 in a state of a single maximum stroke.

Further, considering that the moving rod 31 needs to perform linear reciprocating motion to drive the rotating member 2 to rotate during each motion, in order to facilitate automatic resetting of the moving rod 31, the embodiment adds a spring 33 in the driving member 3. Specifically, one end of the spring 33 is connected to the base 1, 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 movement bar 31 reaches the limit position in a single movement (right movement in the drawing), the spring 33 will be stretched (or compressed) to the limit and then automatically reset to the initial position by the elastic force.

In general, considering that the convex teeth 32 provided on the moving rod 31 need to form an abutting collision with the gear teeth on the rotating member 2, the surface of the convex teeth 32 may be provided in a smoothly transitive wedge-shaped tooth shape so as to lightly and slowly collide with the gear teeth on the rotating member 2 during the going-back of the moving rod 31, thereby slightly rotating the rotating member 2 clockwise, then rapidly and heavily collide with the gear teeth on the rotating member 2 under the elastic force of the spring 33 during the returning-back, thereby rotating the rotating member 2 counterclockwise at a large angle, and the detection data of the detector 4 only need to record the rotation angle of the rotating member 2 during the returning-back of the moving rod 31.

Further, in order to facilitate the connection between the spring 33 and the moving rod 31, the present embodiment is provided with a connection table 34 on the rod body of the moving rod 31. Specifically, the connecting table 34 protrudes from the surface of the rod body of the moving rod 31, and is generally located on two opposite sides of the moving rod 31 with respect to the teeth 32. The other end of the spring 33 can be connected to the wall surface of the connecting table 34, so that 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 reciprocation, the present embodiment is further provided with a guide rail 6 on the base 1. Specifically, the length direction of the guide 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 rail 6, so that the guide rail 6 is used to guide the linear movement of the moving rod 31, and prevent the shaking or vibration during the movement.

Moreover, considering that the amount of expansion and contraction deformation of the spring 33 is not too large when the moving rod 31 moves, otherwise, the too large elastic force easily causes the too large impact force between the convex teeth 32 and the rotating member 2, which may cause damage, the present embodiment is further provided with the limiting block 7 on the base 1. Specifically, the limiting block 7 is located at one side of the motion rod 31 in the single-way motion direction, and is mainly used for forming an abutting connection with a connection table 34 arranged on the motion rod 31 to limit the maximum stroke of the motion rod 31 in the single stroke and limit the maximum deformation amount of the spring 33.

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

In a preferred embodiment with respect to the random number generator 5, the random number generator 5 mainly comprises an ADC module 51 and a number generation module 52. The ADC (Analog to digital converter, analog-digital conversion) 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 value generation module 52 is in signal connection with the ADC module 51, and is mainly configured to generate a value, i.e. a random number, according to the digital quantity generated by the ADC module 51. In general, 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 the 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.
