The ratio of the rotation speed to the parameter adjustment speed of the existing rotary encoder is uniformly increased, various parameter settings or adjustments are involved in the process of using the device by a user, if the parameter setting or adjustment is needed to be wider, such as 1-1000, usually the parameter is increased or decreased by 20 when the rotary encoder rotates one circle, then the rotary encoder rotates 50 circles from 1 to 1000 to reach the maximum 1000, the adjustment is quite laborious and time-consuming, and the user experience is poor.
Of course, it is also possible to use a common circuit or program to control the frequency multiplication from 20 to 200, but the disadvantages come from that the parameter is increased or decreased by 1 for 1/20 turns, and the parameter is increased or decreased by 10 for 1/20 turns, so that the high resolution setting or adjustment cannot be realized, and the user can hardly find the desired value, the deviation of the value is large after stopping the rotation, and the fine adjustment is performed step by step, which wastes time.
Therefore, a problem to be solved by those skilled in the art is how to solve the problem that the conventional rotary encoder has low adjustment efficiency or cannot accurately adjust when faced with a wide parameter range.

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.
The core of the invention is to provide a method for rotating and adjusting parameters of a rotary encoder, which can realize the rapid adjustment of parameters in a large range and also can realize the accurate adjustment of parameters in a small range when facing to values with wider parameter ranges. Another core of the present invention is to provide a system for rotary parameter adjustment of a rotary encoder.
Referring to fig. 1 and 2, fig. 1 is a flow chart of an embodiment of a method for adjusting a parameter of a rotary encoder according to the present invention; fig. 2 is a schematic diagram showing the relationship between the number of pulses output from the rotary encoder and the rotation speed when a is 20 and b is 2.
The invention provides a method for adjusting parameters of a rotary encoder in a rotating mode, which comprises the following steps: acquiring the rotating speed v of a rotary encoder; judging whether the rotating speed v is larger than 1 r/s: if not, controlling the rotary encoder to output a pulse every 1/a circle of rotation; if yes, controlling the rotary encoder to rotate every time
Outputting a pulse by the coil; wherein a and b are both positive numbers greater than 1.
The rotary encoder is used for adjusting numerical parameters, and a user can adjust the numerical value by rotating the rotary encoder, such as adjusting volume, frequency and the like by the rotary encoder.
In the present invention, the rotation speed of the rotary encoder and the acceleration of the parameter adjustment are proportional to each other, that is: the faster the rotation speed, the faster the acceleration of the parameter adjustment increases and decreases. Specifically, when the rotating speed of the rotary encoder is less than or equal to 1r/s, the number of pulses output by the rotary encoder in one rotation is a, and one pulse is output by the rotary encoder in every 1/a rotation, so that fine adjustment of a single increment is realized, and high-resolution adjustment can be completed.
That is, when the rotation speed of the rotary encoder is low, the number of output pulses corresponding to the rotary encoder is relatively small, wherein a is the minimum number of pulses output by one rotation of the rotary encoder in a low-speed state, so as to realize high-resolution adjustment of the numerical parameter.
When the rotating speed is greater than 1r/s, the rotating speed is increased by b times every time the rotating speed is increased by 1, wherein a and b are positive numbers greater than 1, for example, when b is 2 and the rotating speed is 2r/s, the number of pulse outputs corresponding to one rotation of the rotating encoder is 2a, and the numerical range of adjustment of the rotating encoder per second is 4 a; when b is 2 and the rotating speed is 3r/s, the corresponding pulse output number of one rotation of the rotary encoder is 4a, and the numerical range of the adjustment of the rotary encoder per second is 12 a; by analogy, the faster the rotation speed of the rotary encoder is, the faster the parameter adjustment speed is, so as to realize the rapid adjustment of the parameters in a large range.
Therefore, the method for adjusting the parameter of the rotary encoder provided by the invention increases the acceleration adjusted by the parameter of the rotary encoder according to the corresponding proportion along with the rotating speed of the rotary encoder, when the rotating speed is equal to or less than 1r/s, namely the rotating speed of the rotary encoder is smaller, the number of output pulses of one rotation of the rotary encoder is a, a is the minimum number of pulses output by one rotation of the rotary encoder in a low-speed state, and the value of a can be flexibly set according to the requirement so as to ensure that the accurate adjustment of the parameter in a small range can be realized.
When the rotating speed is more than 1r/s, the number of output pulses corresponding to one rotation of the rotary encoder is a multiplied by b along with the increase of the rotating speedv-1That is, the number of output pulses corresponding to one rotation of the rotary encoder is increased by b times every time the rotation speed is increased by 1, and a and b are positive numbers larger than 1, that is, the faster the rotation speed of the rotary encoder is, the larger the acceleration of parameter adjustment is, thereby realizing the rapid adjustment of parameters in a large range.
In addition to the above-described embodiments, in consideration of the specific setting of the number of pulses output by the rotary encoder per rotation, it is preferable to control the rotary encoder to output one pulse per 1/20 rotations if the rotation speed v is less than or equal to 1 r/s. That is, in this embodiment, the minimum number of pulses output by one rotation of the rotary encoder corresponding to the low-speed state is 20, and then one pulse is output every time 1/20 rotations pass, so that fine adjustment of a single increment is realized, accurate adjustment of a small-range parameter is ensured, and high-resolution adjustment is completed.
On the basis of the above embodimentsConsidering the setting of a specific ratio of the acceleration of the parameter adjustment of the rotary encoder to increase with its rotation speed, it is preferable to control the rotary encoder to rotate every time if the rotation speed v is greater than 1r/s
The loop outputs a pulse.
That is, in this embodiment, when the rotation speed is 2r/s, and the number of pulse outputs corresponding to one rotation of the rotary encoder is 40, the number of the adjustment values per second of the rotary encoder is 80; when the rotating speed is 3r/s, the number of pulse outputs corresponding to one rotation of the rotary encoder is 80, and the numerical range of the rotary encoder adjusted every second is 240; and so on.
In addition to the above embodiments, in order to further increase the efficiency of adjusting parameters of the rotary encoder in a wide range, it is preferable that the rotary encoder is controlled to rotate every time when the rotation speed v is greater than 1r/s
The loop outputs a pulse. That is, in this embodiment, when the rotation speed is 2r/s, and the number of pulse outputs corresponding to one rotation of the rotary encoder is 60, the number of the adjustment values per second of the rotary encoder is 120; when the rotating speed is 3r/s, the number of pulse outputs corresponding to one circle of rotation of the rotary encoder is 180, and the numerical range of adjustment of the rotary encoder per second is 540; by analogy, the faster the rotation speed of the rotary encoder is, the faster the parameter adjustment speed is, so as to realize the rapid adjustment of the parameters in a large range.
If the adjustment range is larger, the minimum number of pulses output by the rotary encoder corresponding to one rotation in the low-speed state can be further increased, and specifically, if the rotation speed v is less than or equal to 1r/s, the rotary encoder is controlled to output one pulse every 1/200 rotations. On the basis of the above-described embodiment, it is preferable that the rotary encoder is controlled to rotate every rotation if the rotation speed v is greater than 1r/s
The loop outputs a pulse. In this embodiment, a is 200 and b is 2. Of course, a and b can be set to other values as required to meet the adjustment requirements of different parameter ranges.
In addition to the above method for adjusting the parameter of the rotary encoder, the present invention also provides a system for adjusting the parameter of the rotary encoder, comprising:
a rotational speed acquisition means for acquiring a rotational speed v of the rotary encoder;
pulse control means for determining whether or not the rotation speed v is greater than 1 r/s:
if not, controlling the rotary encoder to output one pulse every 1/a circle of rotation;
if yes, controlling the rotary encoder to rotate every time

wherein a and b are both positive numbers greater than 1;
the rotating speed acquisition device is connected with the pulse control device.
Preferably, the pulse control device controls the rotary encoder to output one pulse per 1/20 rotations if the rotating speed v is less than or equal to 1 r/s.
