In the method for converting the waveform check driving device control command by using the control command provided by the present invention, the combined embodiments thereof are numerous, and therefore will not be further described herein, and only two preferred embodiments are specifically described.

Please refer to the first figure, which is a block diagram showing the control system of the first preferred embodiment of the present invention. As shown in the figure, a method for converting a waveform check driving device control command by using a control command according to a first preferred embodiment of the present invention is applied to a control system 1 including a logic control device 11 and a plurality of A connecting line 12 (only one is shown in the figure) and a driving device 13, the logic control device 11 is a programmable logic controller, but other embodiments are not limited thereto.

The connecting wires 12 can be existing electrical connecting wires and can be plugged into the logic control device 11. The driving device 13 is a servo driver, and is generally electrically connected to the motor to drive the motor. However, the other embodiments are not limited thereto, and the connecting wires 12 are also plugged into the driving device 13 so that the logic control device 11 passes through the The connecting wires 12 are electrically connected to the driving device 13 .

The logic control device 11 is configured to transmit a plurality of control commands S1 (only one indicated) to the driving device 13 via the connecting lines 12, and control the driving device 13 to drive the motor with the control command S1.

Please refer to the first to third figures together. 2 is a flow chart showing a method for converting a control command of a waveform check driving device by using a control command according to a first preferred embodiment of the present invention, and the third figure shows the present invention. A waveform diagram of a control waveform of the first preferred embodiment. As shown in the figure, the above method can be realized by electrically connecting a check device 2 to the logic control device 11 (other embodiments can be electrically connected to the drive device 13), and the check device 2 can generally be set. Such as a central processing unit (CPU) processor, an existing display, and a memory such as a memory, the above methods are all performed by the above-mentioned checking device, and include the following steps: Step S101: Capture each control command S1 corresponding to the connection lines 12, and correspondingly convert the control commands S1 into a plurality of control waveforms 100, 200, and 300 (as shown in the third figure), according to one unit. The analysis time interval T splits each control waveform 100, 200, and 300 into a plurality of unit bands 1001, 1002, 1003, 2001, 2002, 2003, 3001, 3002, and 3003 arranged in a time sequence, and each unit band 1001, 1002 , 1003, 2001, 2002, 2003, 3001, 3002 and 3003 belong to a high potential band or a low potential band.

Specifically, the unit bands 1001, 2002, 3001, and 3002 belong to a low potential band (for example, a digital waveform of 0), and the unit bands 1002, 1003, 2001, 2003, and 3003 belong to a high potential band (for example, a digital waveform). 1), and the above chronological order is the time sequence of 0 to t1, t1 to t2, and t2 to t3, etc., in order.

Step S102: according to the unit bands 1001, 1002, 1003, 2001, 2002, 2003, 3001, 3002, and 3003 belonging to a high potential band or a low potential band, the unit bands 1001, 1002, 1003, 2001, 2002, 2003 , 3001, 3002 and 3003 are converted into a plurality of The chronologically arranged conversion numbers are used to generate a time-series digital array.

Specifically, in the first preferred embodiment of the present invention, since it is a digital waveform, the high potential band can be defined as 1 through the built-in analysis rule, and the low potential band is defined as 0, for example, by looking up the table method. The potential value of the high potential band is defined as 1 in the table, and the potential value in the low potential band is defined as 0 in the table; or it is realized by a program, for example, directly to the high potential band and Compared with the low potential band, the potential value is 1 for the high potential and 0 for the low potential, which depends on the design of the practice.

Through the above conversion, the unit bands 1001, 1002, 1003, 2001, 2002, 2003, 3001, 3002, and 3003 can be converted into the following sequential digital arrays (the converted numbers after t3 are omitted):

Step S103: Capture a preset correct timing digital array, and the correct timing digital array includes a plurality of correct conversion numbers arranged in chronological order, wherein the correct timing digital array is, for example, the following array (not limited thereto):

Step S104: Correspondingly comparing the converted numbers and the correct converted numbers according to the chronological order, thereby determining whether the timing digital array is the same as the correct timing digital array.

Specifically, in this step, whether the converted digits are identical to the correct converted digits can be directly determined by way of array alignment. If the determination result is yes, the execution step ends; if the determination result is no Then, the following step S105 is performed.

Step S105: Define, according to the chronological order, at least one of the converted digits and the corresponding correct converted digits as at least one of the to-be-confirmed converted digits, and parse the at least one converted digit in the chronological order. Time sorting.

For example, from the timing digital array and the correct timing digital array described above, it can be known that t1 to t2 of the control waveform 100 in the time series digital array are different from t1 to t2 of the control waveform 100 in the correct timing digital array, and the control waveform 200 The t2 to t3 are different from t2 to t3 of the control waveform 200 in the correct timing digital array, and t1 to t2 of the control waveform 300 are different from t1 to t2 of the control waveform 300 in the correct timing digital array.

Therefore, the checking device 2 can define the above-mentioned number as the first converted digit to be confirmed, and analyze the difference t1 to t2 of the control waveform 100. The control waveform 200 has different t2 to t3, and the control waveform 300 has different t1 to t2. And preferably, the above results are also displayed through the display, so that the user can clearly understand the difference in the converted numbers in the control waveforms 100, 200 and 300 in the above time sorting.

In addition, in step S103, at least one of the correct conversion numbers in the correct timing digital array is set to at least one set conversion number, for example, the control waveform 200 in the correct timing digital array. The numbers in t2 to t3 are set to set the conversion number, indicating that in other modified versions, the modification of the portion t2 to t3 of the control waveform 200 is permitted.

Therefore, in step S105, the at least one to-be-confirmed converted digit is further compared with the at least one set-converted digit, and when at least one of the at least one to-be-confirmed converted digits matches the at least one set-converted digit Excluding the time-ordered order of the at least one converted number in the chronological order.

For example, as can be seen from the above, t1 to t2 of the control waveform 100 are different from t1 to t2 of the control waveform 100 in the correct timing digital array, and t2 to t3 of the control waveform 200 are different from t2 to the control waveform 200 in the correct timing digital array. T3, t1 to t2 of the control waveform 300 are different from t1 to t2 of the control waveform 300 in the correct timing digital array, but t2 to t3 of the control waveform 200 are set to set the conversion number, and therefore, the control will not be performed in step S105. The time ordering of t2 to t3 of the waveform 200 is resolved, and only t1 to t2 of the control waveform 100 and t1 to t2 of the control waveform 300 are parsed.

For example, as described above, t2 to t3 of the control waveform 200a are set to set the conversion number. Therefore, the time sequence of t2 to t3 of the control waveform 200a is not further analyzed in step S212, and only the control is parsed. Between t1 and t2 of the waveform 100a and t1 to t2 of the control waveform 300a.

In addition, in step S214, the at least one second to-be-confirmed converted digit is further compared with the at least one set-converted digit, and at least one of the at least one second to-be-confirmed converted digit and the at least one When setting the conversion number match, the time ordering of the at least one converted number in the chronological order is excluded.

For example, as described above, t2 to t3 of the control waveform 200a are set to set the conversion number. Therefore, the time sequence of t2 to t3 of the control waveform 500a is not further analyzed in step S212, and only the control is parsed. From t1 to t2 of the waveform 400a and t2 to t3 of the control waveform 600a.
