DETAILED DESCRIPTION

Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

In the description of the present invention, "several" means one or more, "multiple" means more than two, greater than, less than, and exceeding are understood as not including the number itself, and "above", "below", and "within" are understood as including the number itself. If there is a description of "first", "second", etc., it is only used for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

In the description of the present invention, unless otherwise clearly defined, words such as “setting”, “installation” and “connection” should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above words in the present invention based on the specific content of the technical solution.

In order to monitor the laser energy, the relevant technology usually uses an oscilloscope to monitor the waveform of the laser energy, but the laser equipment will not be connected to the oscilloscope all the time during the actual operation, and it is impossible to arrange special personnel to observe the oscilloscope all the time. Therefore, it is necessary to collect data on the laser energy through a program to facilitate the subsequent analysis of the laser energy. However, due to the limitations of the acquisition hardware, the accuracy of the program's acquisition frequency of laser energy data is limited. For example, the highest acquisition accuracy is 1μs (microseconds), that is, the minimum acquisition time interval is 1μs. It should be known that the smaller the acquisition time interval, the higher the acquisition frequency and the higher the acquisition accuracy. Since the acquisition frequency of laser energy data is not high enough, for laser energy with a fixed period, the data points that can be collected within one period are fixed. For example, for laser energy with a period length of 25μs, if the acquisition time interval is 1μs, only 25 data points can be collected for one period of laser energy. Since the acquisition accuracy is not high enough, the waveform of the laser energy restored by using 25 data points is quite different from the actual waveform of the laser energy, and the sampling signal and the laser energy both show periodic changes. Even if the laser energy of multiple consecutive cycles is collected, the relative time of the data points collected in each cycle is consistent within the cycle. For example, starting from the starting point of the laser energy cycle, a data point is collected every 1μs, and the collection time of the first data point is recorded as 1μs, then the collection time of the second data point is 2μs, and the collection time of the third data point is 3μs, and so on until the end of the laser energy cycle. This results in the data collected in each cycle losing key data points, and the restored waveform will also be distorted. Therefore, this embodiment provides a laser energy data acquisition and restoration method, device, laser equipment and storage medium, which can improve the acquisition accuracy of laser energy data.

Please refer to Figure 1. This embodiment discloses a laser energy data collection and restoration method, including steps S100 to S400. It should be noted that the steps in this embodiment are numbered only for the convenience of review and understanding, rather than limiting the execution order of the steps. In actual applications, adaptive adjustments can be made according to the logical relationship between the steps. The contents of each step are described in detail below:

S100, determining a target acquisition step length, where the target acquisition step length includes a minimum acquisition step length and an expected acquisition step length, where the minimum acquisition step length is used to characterize a minimum acquisition time interval at the highest acquisition accuracy, and the expected acquisition step length is used to characterize an acquisition time interval at the expected acquisition accuracy;

For example, the highest acquisition accuracy varies according to different application requirements. For example, the highest acquisition accuracy can be 10μs, 5μs, 1μs or 0.1μs, etc., that is, the device can only collect data once every 10μs, 5μs, 1μs or 0.1μs at the fastest. Under the highest acquisition accuracy, the user can set the acquisition time interval according to the actual application requirements. For example, for a device with a maximum acquisition accuracy of 1μs, the user can set the acquisition time interval to 1μs, 1.5μs, 2μs, 2.55μs, etc. As long as the acquisition time interval is not less than the minimum acquisition time interval under the highest acquisition accuracy, the device can collect data on the laser energy at the acquisition frequency corresponding to the acquisition time interval. In order to restore the actual laser waveform as much as possible, the relevant technology usually uses the minimum acquisition time interval (for example, 1μs) under the highest acquisition accuracy for data acquisition, but it still cannot meet the requirements, for example, it cannot meet the acquisition requirements of higher accuracy levels such as 0.1μs, 0.01μs or 0.001μs. In this embodiment, the acquisition time interval (i.e., the target acquisition step length) is adjusted without changing the highest acquisition accuracy of the device, so that the data points collected in each period of multiple consecutive periods are staggered at relative moments within the period, so as to achieve higher data accuracy.

For example, the minimum acquisition time interval (i.e., the minimum acquisition step length) at the highest acquisition accuracy is 1 μs, and the expected acquisition accuracy is 0.01 μs, then the expected acquisition step length can be 0.01 μs, and the target acquisition step length is 1.01 μs; similarly, if the expected acquisition accuracy is 0.1 μs or 0.001 μs, the target acquisition step length can be determined as 1.1 μs or 1.001 μs. In short, the target acquisition step length can be determined according to the sum of the minimum acquisition step length and the expected acquisition step length, that is, step S100, determining the target acquisition step length, including: S110, determining the target acquisition step length according to the sum of the minimum acquisition step length and the expected acquisition step length. It should be noted that the expected acquisition step length can be set according to multiple factors such as application requirements, device computing power, and program computing power, so as to determine the appropriate target acquisition step length, that is, the sampling period of the laser energy. Among them, in order to achieve the ideal acquisition effect, the expected acquisition step length should be the minimum acquisition time interval under the expected acquisition accuracy and the last digit value should be an odd number.

S200, based on the target acquisition step length, a plurality of cycles of continuous target laser energy are acquired to obtain a first laser energy data sequence, wherein the number of cycles of target laser energy acquisition is determined according to a maximum acquisition accuracy and an expected acquisition accuracy, and the first laser energy data sequence includes a first acquisition sequence number and corresponding laser energy data;

For example, in actual use, laser energy is a periodic continuous waveform. For the convenience of analysis, part of the laser energy (i.e., target laser energy) can be sampled and analyzed. In actual application, real-time data collection of the target laser energy can be performed, and then part or all of it can be restored. It should be known that the laser energy waveform has two dimensions of data. The first dimension is the time dimension, i.e., the horizontal axis of the waveform, and the second dimension is the laser energy data, i.e., the vertical axis of the waveform. The two dimensions of data form data points in pairs.

Please refer to Figures 2, 3 and 4. For ease of understanding, for the same laser energy, sampling begins at the same starting time. _t0 is used to represent the sampling time change sequence of the related technology, and t is used to represent the sampling time change sequence of this embodiment. In the related technology, the collection step of laser energy data is 1μs. Since the laser energy changes periodically, for laser energy with a cycle length of 25μs, 25 data points can be collected in one cycle. Since the cycle length is an integer multiple of the collection step, in the time dimension, the relative distance between the relative sampling moment of each cycle and the cycle starting point of the laser energy corresponding cycle is the same, then the laser energy data (denoted as power) corresponding to the data points collected in each cycle is the same. The target acquisition step size of this embodiment is determined by the sum of the minimum acquisition step size and the expected acquisition step size, that is, 1μs+0.01μs=1.01μs. Please refer to Figures 4 and 5. From the time difference Δt between _t0 and t, it can be seen that Δt gradually accumulates with the change of time. Within a certain number of cycles, the relative sampling time of each cycle is staggered. The related technology can only collect laser energy data of the order of 1μs (for example, _t0 = 1μs, 2μs, 3μs...), while this embodiment can collect laser energy data of the order of 0.01μs (for example, t=1.01μs, 2.02μs, 3.03μs...). Among them, the order of magnitude usually refers to the scale or level of the quantity, and a fixed ratio is maintained between each level, and these ratios are usually powers of 10. For example, 10, 100, 1000, etc. are all powers of 10, which represent different orders of magnitude. The concept of order of magnitude is used to describe the size relationship between two numbers. For example, if one number is 10 times another number, then it can be considered that the two numbers differ by one order of magnitude.

So far, compared with the related art, although the present embodiment realizes the staggered acquisition of laser energy data in the time dimension by adjusting the target acquisition step size, the number of data points collected in each cycle has not increased because the acquisition accuracy has not changed (still 1μs), that is, the acquisition accuracy of a single cycle has not been improved. However, please refer to Figure 6, because the laser energy has the characteristic of periodic change, that is, in different cycles, at the same time as the cycle starting point, the laser energy data (power) is the same, that is, if the waveforms of laser energy of different cycles are translated to the same cycle starting point in the time dimension, the waveforms of laser energy of all cycles will overlap and present as a waveform of one cycle. As described above, the laser energy data realizes staggered acquisition in the time dimension, and the order of magnitude of the sampling moment is 0.01μs. Then, within a certain number of cycles, if the laser energy data of different cycles are translated in the time dimension, the laser energy data of a single cycle can be obtained, and the time difference between two adjacent data points is 0.01μs, that is, the acquisition time interval is 0.01μs, that is, the data accuracy of the laser energy data can be improved to 0.01μs.

Please refer to Figures 6 and 7. In order to achieve the superposition of laser energy data of multiple cycles, the laser energy waveform of a single cycle obtained after superposition can be abstracted into multiple data points. The horizontal coordinate of each data point can be represented by the serial number index, and the vertical coordinate can be represented by power. Similarly, before the data is superimposed, the laser energy data of multiple cycles are arranged in sequence in the time dimension, and the horizontal coordinate of each data point can be represented by the serial number index0. Since the laser energy data will not change before and after superposition, the vertical coordinate is also represented by power. Therefore, the first laser energy data sequence can be represented by an array: [index0, power].

When collecting laser energy data, for laser energy with a cycle length of 25μs, if the highest collection accuracy is 1μs, then at most 25 data points can be collected per cycle. If the collection accuracy is to reach 0.01μs, then the number of data points for one cycle of laser energy is 2500, that is, the laser energy waveform of a single cycle obtained after superposition needs to be abstracted into 2500 data points, that is, data collection is required for 100 cycles of continuous laser energy. It can be seen that the number of cycles for target laser energy collection can be determined based on the highest collection accuracy and the expected collection accuracy.

Specifically, the number of cycles for target laser energy collection is determined based on the highest collection accuracy and the expected collection accuracy, including:

S210, determining a magnitude difference of acquisition accuracy according to the highest acquisition accuracy and the expected acquisition accuracy;

S220, determining the number of cycles for collecting target laser energy according to the difference in the level of collection accuracy.

In the above example, the highest acquisition accuracy is 1μs, i.e., ^100μs , while the expected acquisition accuracy is 0.01μs, i.e., ^10-2μs . The difference in the acquisition accuracy between the two is ^102. Therefore, the number of cycles for target laser energy acquisition can be determined as 100. For another example, if the highest acquisition accuracy is 1μs, and the expected acquisition accuracy is 0.001μs, i.e., ^10-3μs , then the number of cycles for target laser energy acquisition can be determined as ¹⁰³ , i.e., 1000. For another example, if the highest acquisition accuracy is 0.1μs, i.e., ^10-1μs , and the expected acquisition accuracy is 0.001μs, i.e., ^10-3μs , then the number of cycles for target laser energy acquisition can be determined as ¹⁰² , i.e., 100. It should be conceived that in the actual acquisition process, the number of cycles for data acquisition of target laser energy can be more, but the laser energy data of a suitable number of cycles are taken for analysis.

S300, based on a preset serial number mapping model, convert the first acquisition serial number into a second acquisition serial number to obtain a second laser energy data sequence, where the second laser energy data sequence includes the second acquisition serial number and laser energy data;

Exemplarily, taking the target acquisition step length of 1.01μs and the number of acquisition cycles of 100 as an example, part of the data of the first laser energy data sequence is shown in FIG8, wherein the data shown in the power column is only an example and has no substantive meaning. Since the first laser energy data sequence is acquired in chronological order, the sequence number index0 (i.e., the first acquisition sequence number) is arranged in sequence, that is, when index0 is 1, 2, 3..., it represents the 1st, 2nd, 3... data points in turn. In order to restore the waveform of the laser energy of a single cycle, it is necessary to determine the sequence number index corresponding to each laser energy data (power), that is, to convert index0 into index. This embodiment is based on the sequence number mapping model, converts the first acquisition sequence number into the second acquisition sequence number, and obtains the second laser energy data sequence, wherein FIG9 shows part of the data of the first acquisition sequence number and the second laser energy data sequence. It should be noted that the laser energy data (power) does not change during the sequence number conversion process.

S400, sorting the second laser energy data sequence based on the second acquisition sequence number to obtain a third laser energy data sequence.

Exemplarily, after the conversion of the serial number mapping model, the serial number of each laser energy data (power) in a single cycle (i.e., the relative position with respect to the starting point of the cycle) can be determined after the cycle overlap. Please refer to FIG10, and sort the second laser energy data sequence (i.e., array [index, power]) based on the second acquisition serial number (serial number index), so that the laser energy data (power) of multiple cycles are arranged in sequence according to the serial number in a single cycle, thereby displaying the waveform of a single cycle of laser energy (as shown in FIG7). Before and after the cycle overlap, the number of data points remains unchanged, but the time interval between adjacent data points is reduced to 0.01 μs (i.e., the minimum time interval under the desired acquisition accuracy), so as to achieve the purpose of transforming the laser energy data from low acquisition accuracy to high acquisition accuracy.

Therefore, by adjusting the target acquisition step size, acquiring multiple cycles of target laser energy based on the target acquisition step size, and performing serial number conversion on the acquired data based on the serial number mapping model, multiple cycle laser energy data with lower acquisition accuracy can be restored to single cycle laser energy data with higher acquisition accuracy, which is beneficial to improving the acquisition accuracy of laser energy data.

Step S300, based on a preset serial number mapping model, converting the first acquisition serial number into a second acquisition serial number to obtain a second laser energy data sequence, including:

S310, determining a magnitude difference of acquisition accuracy according to the highest acquisition accuracy and the expected acquisition accuracy;

For example, the highest acquisition accuracy is 1μs, i.e. ^100μs , and the expected acquisition accuracy is 0.01μs, i.e. ^10-2μs , then the acquisition accuracy order difference is ¹⁰² ; for another example, the highest acquisition accuracy is 1μs, i.e. ^100μs , and the expected acquisition accuracy is 0.001μs, i.e. ^10-3μs , then the acquisition accuracy order difference is ¹⁰³ ; for another example, the highest acquisition accuracy is 0.1μs, i.e. ^10-1μs , and the expected acquisition accuracy is 0.001μs, i.e. ^10-3μs , then the acquisition accuracy order difference is ¹⁰² .

S320, determining a first operation factor according to the target acquisition step length and the acquisition accuracy magnitude difference;

Exemplarily, step S320 includes: determining a first operation factor according to the product of the target acquisition step length and the acquisition accuracy magnitude difference.

For example, assuming that the target acquisition step is I and the acquisition accuracy level is 10 ⁿ (n is a positive integer), the first operation factor K ₁ =I×10 ⁿ .

S330, determining a second operation factor according to the cycle length of the target laser energy and the magnitude difference of the acquisition accuracy;

Exemplarily, step S330 includes: determining a second operation factor according to the product of the cycle length of the target laser energy and the acquisition accuracy level difference.

For example, assuming that the cycle length of the target laser energy is T and the acquisition accuracy level is 10 ⁿ (n is a positive integer), the second operation factor K ₂ =T×10 ⁿ .

S340: Based on the first operation factor and the second operation factor, convert the first acquisition sequence number into a second acquisition sequence number to obtain a second laser energy data sequence.

Exemplarily, step S340 includes: taking the modulus of a second operational factor according to the product of the first acquisition sequence number and the first operational factor, and determining a second acquisition sequence number to obtain a second laser energy data sequence.

For example, let the first acquisition serial number be index0, the second acquisition serial number be index, and the laser energy data be power. Then the first laser energy data sequence is represented by an array as: [index0, power], and the second laser energy data sequence is represented by an array as: [index, power]. The mapping relationship between the first acquisition serial number and the second acquisition serial number can be expressed as: index = index0×K ₁ % K ₂ = index0×(I×10 ⁿ )%(T×10 ⁿ ), where % represents the remainder operation. In the serial number mapping process, the serial numbers of data points of multiple cycles are converted into the serial numbers of data points of one cycle, and the parameter power is not involved in the operation. Therefore, the value of the power sequence and its relative position do not change. When the second laser energy data sequence is sorted based on the serial number index, it is equivalent to arranging multiple data points scattered in one cycle according to the serial number, thereby restoring the waveform of the laser energy of one cycle, which is conducive to improving data accuracy.
