Then, a first resolution value is calculated according to the calculation frequency value and the variation frequency value. Then, whether the first resolution value is larger than or equal to the minimum resolution judgment value is judged.

Detailed Description
The invention will be described in detail with reference to the following drawings, which are provided for illustration purposes and the like:
referring to fig. 1, fig. 1 is a block diagram of a command generating apparatus according to a preferred embodiment of the invention. As shown in the drawings, the preferred embodiment of the present invention provides a command generating apparatus 1. The command generating device 1 comprises a command generating module 11, an operation module 12 and a judgment module 13. In the present embodiment, the command generating device 1 is a Field Programmable Gate Array (FPGA), but the invention is not limited thereto in other embodiments.
The command generating module 11 is electrically connected to an electronic device 2. The electronic device 2 may be a servo driver or a servo motor, but not limited thereto. The operation module 12 is electrically connected to the command generating module 11 and includes a divider 121 and a multiplier 122. The operation module 12 may be a hardware processor or a software operation program. The hardware processor may be a central processing unit or a microprocessor, and the software operation program may be implemented by program languages such as ASP, C/C + +/C #, JAVA, Python, PHP, Perl, but not limited thereto.
The determining module 13 is electrically connected to the calculating module 12 and has a minimum resolution determining value 131. The determining module 13 may be a central processing unit, a microprocessor or a software determining program, and the software determining program may be implemented by program languages such as ASP, C/C + +/C #, JAVA, Python, PHP, Perl, but not limited thereto.
Referring to fig. 1 to 3, fig. 2 is a flowchart illustrating a method for adjusting resolution of a control command of an electronic device according to a preferred embodiment of the invention; FIG. 3 is a waveform diagram of a control command with a first resolution according to a preferred embodiment of the present invention. As shown in fig. 1-3, a method for adjusting the resolution of a control command of an electronic device is provided in the preferred embodiment of the present invention. The resolution adjustment method of the electronic device control command is applied to the command generating device 1 for adjusting a control command C generated by the command generating module 11 of the command generating device 1. The control command C may be a sine wave or a square wave, but not limited thereto. First, the minimum resolution determination value 131 is established in the determination module 13 (i.e., step S1). In the present embodiment, the minimum resolution determination value 131 is 95, but it is not limited thereto in other embodiments.
Then, the operation module 12 analyzes an operation frequency value corresponding to the command generating device 1, and receives the control command C generated by the command generating module 11, so as to analyze a variation frequency value corresponding to the control command C (i.e., step S2). In the present embodiment, the operation frequency value is 10 times per second, but the invention is not limited thereto in other embodiments. In addition, in the embodiment, the frequency variation value is 1 time per second, but the invention is not limited thereto in other embodiments. That is, the control command C has a variation period of 1 second, so that within 1 second, the variation angle position is changed from the starting point to 1, then decreased from 1 to-1, and finally changed to 0. Since the calculation frequency is 10 times per second, the variation angle position of the control command C is calculated every 0.1 second.
Then, the calculating module 12 calculates a first resolution value V1 according to the calculation frequency value and the variation frequency value (i.e., step S3). The divider 121 divides the operation frequency value by the variation frequency value to generate a first resolution value V1. In the present embodiment, the first resolution value V1 is 10, but it is not limited thereto in other embodiments. Next, the determining module 13 receives the first resolution value V1 and determines whether the first resolution value V1 is greater than or equal to the lowest resolution determination value (i.e., step S4). If the determination result is yes, the trigger command generating module 11 outputs the control command C to the electronic device 2 according to the first resolution value V1.
Referring to fig. 1, fig. 2 and fig. 4 together, fig. 4 is a waveform diagram of a control command with a second resolution according to a preferred embodiment of the invention. As shown in fig. 1-2 and 4, if the determination result is negative, the determining module 13 transmits a determination signal S to the calculating module 12, so that the calculating module 12 increases the calculating frequency value by a frequency increasing value to be an increasing calculating frequency value (step S5). In the present embodiment, the frequency increment is set to 90, but it is not limited thereto in other embodiments.
Since the first resolution value V1 is 10 and the minimum resolution determination value 131 is 95 in the present embodiment, the first resolution value V1 is smaller than the minimum resolution determination value 131. It is added that the broken line of the waveform of the control command C is long, as is apparent from fig. 3, and thus the waveform thereof looks unsmooth because the first resolution value V1 is too low. Therefore, the operation module 12 calculates the increasing operation frequency value as 100.
Finally, the computing module 12 computes a second resolution value V2 by using the increased computing frequency value and the varied frequency value, so that when the second resolution value V2 is greater than or equal to the minimum resolution determination value 131, the trigger command generating module 11 outputs the control command C with the second resolution value V2 (i.e., step S6). The divider 121 divides the increased operation frequency value by the variation frequency value to generate a second resolution value V2.
In the present embodiment, the divider 121 calculates the second resolution value V2 as 100, so the second resolution value V2 is greater than the minimum resolution determination value 131. It should be added that, as is apparent from fig. 4, the waveform of the control command C is smoother because the second resolution value V2 is higher. Thereby, the trigger command generating module 11 outputs the control command C to the electronic device 2 with the second resolution value V2.
In summary, in the method for adjusting resolution of a control command of an electronic device and the command generating device according to the preferred embodiments of the present invention, the operation module is used to calculate the first resolution value of the control command generated by the command generating module. Then, the judgment module judges whether the first resolution value is larger than or equal to the minimum resolution judgment value. When the first resolution value is greater than or equal to the minimum resolution judgment value, a control instruction with the first resolution value is output to the electronic device.
When the first resolution value is smaller than the minimum resolution judgment value, the frequency increasing value is added to the operation frequency value of the control instruction to form an increasing operation frequency value. And the increasing operation frequency value and the variable frequency value are operated to obtain a second resolution value by the operation module. Finally, whether the second resolution value is larger than the minimum resolution judgment value or not is judged by the judgment module, and when the second resolution value is larger than the minimum resolution judgment value, a control instruction with the second resolution is output to the electronic device.
Compared with the prior art, the method for adjusting the resolution of the control command of the electronic device and the command generating device provided by the preferred embodiment of the invention automatically adjust the resolution of the control command by the command generating module, the calculating module and the judging module, so as to adjust the first resolution value lower than the minimum resolution judging value to the second resolution value, and transmit the control command with the second resolution value to the electronic device.
Therefore, the method for adjusting the resolution of the control command of the electronic device and the command generating device provided by the preferred embodiment of the invention automatically adjust the resolution of the control command without manually observing the waveform of the display module and adjusting the resolution. Therefore, the workload of the user is reduced, and the time required for the control command analysis and adjustment operation is shortened.
The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and it should be understood that various changes and modifications can be effected therein by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
