It is explicitly and implicitly understood by those skilled in the art that the embodiments described in the present invention may be combined with other embodiments.

[0057] like Figure 1 FIG. 1 is a schematic diagram of an implementation environment provided by an embodiment of the present invention. Figure 1 The implementation environment includes at least one terminal 102 and a server 101. The terminal 102 and the server 101 can be connected to a network wirelessly or wired to complete data transmission and exchange.

[0058] Server 101 can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers. It can also be a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, CDN (Content Delivery Network), as well as big data and artificial intelligence platforms.

[0059] In addition, the server 101 can also be a node server in the blockchain network. Blockchain is a new application model of computer technologies such as distributed data storage, peer-to-peer transmission, consensus mechanism, and encryption algorithm.

[0060] The terminal 102 may be a smart phone, a tablet computer, a laptop computer, a desktop computer, a smart speaker, a smart watch, etc., but is not limited thereto. The terminal 102 and the server 101 may be directly or indirectly connected via wired or wireless communication, which is not limited in the embodiment of the present invention.

[0061] Based on the example Figure 1 In the implementation environment shown, an embodiment of the present invention provides a detection data feedback method. The following is explained using the detection data feedback method applied to a terminal 102 (such as a laser processing system) as an example. It can be understood that the detection data feedback method can also be applied to a server 101.

[0062] Reference Figure 2 , Figure 2 The flowchart of the detection data feedback method applied to the terminal provided in the embodiment of the present invention, the execution subject of the detection data feedback method can be any of the aforementioned computer devices (including servers or terminals). Figure 2 , the method comprises the following steps:

[0063] S100, obtaining the acquisition speed of the laser processing system;

[0064] It should be noted that, in some embodiments, obtaining the acquisition speed of the laser processing system may include the following steps: in response to an acquisition signal of the laser processing system, continuously acquiring encoder pulse data of the servo motor in the laser processing system; the acquisition signal includes a start instruction of the laser processing system or an acquisition completion signal of the previous acquisition cycle; the servo motor is used to drive the rotation of the material belt in the laser processing system; starting from the acquisition signal, the continuously acquired encoder pulse data is accumulated and stored until the acquisition completion signal is received, and the encoder pulse data of the corresponding period is obtained according to the accumulated and stored data; based on the encoder pulse data, the speed conversion technology is used to obtain the corresponding acquisition speed; return to execute the step of continuously acquiring the encoder pulse data of the servo motor in the laser processing system in response to the acquisition signal of the laser processing system, and continuously obtain the acquisition speed of the laser processing system.

[0065] It should be noted that, in some embodiments, obtaining the corresponding acquisition speed based on the encoder pulse data using speed conversion technology can include the following steps: converting the collected encoder pulse data into displacement through proportional operation; obtaining the corresponding acquisition speed based on the ratio of the displacement to the cycle time corresponding to the acquisition period.

[0066] For example, in some specific implementations, encoder data acquisition can be implemented as follows: the control system sets the material conveyor belt speed through a servo motor, and through servo encoder data detection and speed conversion technology, realizes real-time calculation of the actual belt speed, ensuring the real-time and effectiveness of the belt speed obtained by the system.

[0067] In some embodiments, the method may further include the following steps: performing smoothing filtering on the acquisition speed. Specifically, the smoothing filtering may include the following steps:

[0068] Obtain the historical speed filter output value of the first cycle and the acquisition speed of the first cycle and the second cycle; the first cycle is the previous cycle of the second cycle;

[0069] According to the historical speed filter output value of the first cycle and the acquisition speed of the first cycle or the second cycle, the speed filter output value of the second cycle is obtained by smoothing filtering in combination with the preset filter coefficient; the speed filter output value of the second cycle is used as the acquisition speed of the second cycle;

[0070] Among them, the expression of the speed filter output value is:

[0071] V f (n) = αV a (n)+(1-α)V f (n-1);

[0072] Where V f (n) represents the speed filter output value of the second cycle; α represents the filter coefficient; when the acquisition speed of the second cycle is greater than the preset speed threshold, V a (n) represents the acquisition speed of the first cycle. When the acquisition speed of the second cycle is not greater than the preset speed threshold, V a (n) represents the acquisition speed of the second cycle; V f (n-1) represents the historical speed filter output value of the first cycle.

[0073] Through the above process, the speed filter output value of each second cycle can be calculated in sequence

[0074] For example, in some specific implementations, the speed calculation based on encoder data acquisition can be implemented as follows: the speed conversion process is combined with a smoothing filter algorithm to reduce the jitter and noise of the encoder output signal caused by mechanical vibration, electrical noise and other factors, prevent abnormal fluctuations in the material belt speed during system operation, and improve the system and control accuracy and stability. Specifically, the smoothing filter algorithm used is:

[0075] V f (n) = αV a (n)+(1-α)V f(n-1);

[0076] Among them, V f (n) is the speed filter output value of this cycle (i.e., the current cycle); α is the filter coefficient; V a (n) represents the speed sampling value of this cycle (i.e., acquisition speed); V f (n-1) is the speed filter output value of the previous cycle.

[0077] S200, obtaining a target power frequency according to the acquisition speed mapping;

[0078] Among them, power frequency includes power and frequency;

[0079] It should be noted that, in some embodiments, obtaining the target power frequency according to the acquisition speed mapping may include the following steps: obtaining a preset maximum speed value, a minimum speed value, a maximum power frequency value, and a minimum power frequency value, and then calculating the target power frequency by combining the acquisition speed with a two-point equation;

[0080] The expression of the two-point equation is:

[0081]

[0082] In the formula, Indicates the target power frequency; Indicates the maximum power frequency; Indicates the minimum power frequency; V f (n) represents the acquisition speed; V max Indicates the maximum speed; V min Indicates the minimum speed.

[0083] For example, in some specific implementations, the adjustment of laser power and frequency with speed can be achieved as follows: the system provides an interactive interface for the user to set the upper and lower limits of speed and power frequency as required, and the system will establish a mapping relationship between the speed range and the power frequency range based on the set data. During the variable speed processing of the material strip, the system uses a two-point equation to match the acquisition speed and power frequency in the mapping relationship, and sends the parameters to the laser. This mechanism enables the laser to follow and adjust according to real-time speed feedback to adapt to changes in the material strip speed. The two-point equation used to calculate power and frequency:

[0084]

[0085] In the formula, is the power or frequency value of the current cycle; The maximum value of the set power or frequency; is the minimum value of the set power or frequency; V f (n) is the effective speed value of the current cycle (i.e., acquisition speed); Vmax is the maximum value of the set speed; V min The minimum value of the set speed.

[0086] Among them, in some embodiments, the method may also include the following steps: based on the pre-divided speed interval range, obtaining the first speed interval where the acquisition speed corresponding to the current cycle is located and the second speed interval where the acquisition speed corresponding to the previous cycle is located; when the first speed interval and the second speed interval are the same speed interval, the laser pulse width is not switched.

[0087] For example, in some specific implementations, before performing the mapping of speed, power and frequency, it is possible to first determine whether the acquisition speed has reached the set node value (determined based on the speed range of the acquisition speed in the previous cycle). If the acquisition speed has not reached the set node value, that is, the acquisition speed has not exceeded the speed range of the previous cycle, then the original laser pulse width can be maintained. Otherwise, the laser power and frequency can be adjusted with speed through the aforementioned two-point equation mapping.

[0088] S400, switching the pulse width of the laser of the laser processing system according to the target power frequency.

[0089] It should be noted that, in some embodiments, switching the pulse width of a laser of a laser processing system according to a target power frequency may include the following steps: transmitting the target power frequency to the laser processing system so that the laser processing system outputs a corresponding PPI instruction timing to the laser; and switching the pulse width of the laser according to the PPI instruction timing.

[0090] Exemplarily, in some specific implementations, dynamic adjustment of pulse width can be implemented as follows: the system supports setting several key nodes within the speed range and configuring corresponding pulse width values ​​for each node. Under different pulse widths, dynamic changes in power and frequency can be achieved to adapt to different processing requirements. During the variable speed processing of the material belt, when the system determines that the material belt speed reaches the node value, it will convert it into the corresponding Laser Mode index according to the pulse width value configured in the node, and output the PPI instruction timing to the laser to switch the pulse width of the laser. This dynamic adjustment mechanism can control the peak and average power of the laser, improve frequency stability, accurately adjust the pulse width and repetition frequency, better adapt to the different operating speeds of the material belt, and improve the efficiency and accuracy of laser processing.

[0091] Among them, the PPI instruction is an instruction used to implement the PPI communication protocol in Siemens PLC (Programmable Logic Controller). The PPI communication protocol is a master-slave communication protocol that allows PLC to exchange data with other devices, and is particularly suitable for the control and communication of industrial robots. The PPI instruction is mainly used to implement point-to-point communication between PLC and peripheral devices, and exchange data through the RS-485 serial communication standard. The PPI protocol is designed based on the ISO / OSI model to ensure interoperability between different devices and systems. The PPI protocol includes multiple layers, from the physical layer to the session layer, and each layer has its specific functions and protocols to ensure the complete transmission of data and error detection.

[0092] In order to explain the principle of the technical solution of the present invention in detail, the overall process of the present invention is described below in combination with some specific embodiments. It is easy to understand that the following is an explanation of the technical principle of the present invention and cannot be regarded as a limitation of the present invention.

[0093] First of all, it should be noted that in view of the shortcomings of the prior art, the present invention provides a control system that dynamically responds to changes in the speed of the material conveyor belt to implement a detection data feedback solution, by real-time monitoring of the material belt speed in the laser processing system and dynamically adjusting the laser power and frequency, as well as accurately controlling the pulse width to adapt to changes in the material belt speed, thereby ensuring uniform distribution of energy during the processing process. This solves the problem of product quality caused by only being able to use fixed laser parameters for processing when the material belt speed changes.

[0094] like Figure 3 As shown, the technical solution of the present invention can be specifically implemented as follows:

[0095] 1. Encoder data acquisition and speed calculation: The control system sets the material conveyor belt speed through the servo motor, and uses the servo encoder data detection and speed conversion technology to realize the instant calculation of the actual belt speed, ensuring the real-time and effectiveness of the belt speed obtained by the system. The speed conversion process is combined with a smoothing filter algorithm to reduce the jitter and noise of the encoder output signal caused by mechanical vibration, electrical noise and other factors, prevent abnormal fluctuations in the belt speed during system operation, and improve the system and control accuracy and stability. Smoothing filter algorithm used:

[0096] V f (n) = αV a (n)+(1-α)V f (n-1);

[0097] Among them, V f (n) is the speed filter output value of this cycle (i.e., the current cycle); α is the filter coefficient; when the speed sampling value of this cycle (i.e., the acquisition speed) is not greater than the preset speed threshold, V a(n) represents the speed sampling value of this cycle. When the speed sampling value of this cycle is greater than the preset speed threshold, V a (n) represents the speed sampling value of the previous cycle; V f (n-1) is the speed filter output value of the previous cycle.

[0098] In some specific application scenarios, encoder pulse data acquisition to achieve speed calculation can be implemented as follows: continuously convert the encoder pulse number into displacement through proportional operation, and then continuously determine whether the speed calculation cycle time has been reached during the acquisition process. If the speed calculation cycle time has not been reached, the displacement is continuously converted based on the collected encoder pulse number until the speed calculation cycle time is reached, and the speed is calculated based on the increments of all displacements converted within the cycle. Specifically, the speed value of the cycle is obtained based on the ratio of the displacement increment to the unit time corresponding to the cycle.

[0099] Among them, in some specific application scenarios, if the speed collected in this cycle is greater than the threshold, the speed recorded in the previous cycle is used; if the speed collected in this cycle is not greater than the threshold, the speed collected in this cycle is used; the system will obtain the speed sampling value, i.e., V, in each cycle a (n), compare this value with the threshold, if V a (n) is greater than the threshold, then the V recorded in the previous cycle is used a (n) Perform filtering operation to obtain V f (n); if V a (n) is not greater than the threshold, the speed sampling value V obtained in this cycle is used a (n) Perform filtering operation to obtain V f (n). After the calculation is completed, the system will record the V a (n) and V f (n) for use in the next cycle.

[0100] 2. Adjustment of laser power and frequency with speed: The system provides an interactive interface for users to set the upper and lower limits of speed and power frequency as required. The system will establish a mapping relationship between speed range and power frequency range based on the set data. During the variable speed processing of the material strip, the system uses a two-point equation to match the acquisition speed and power frequency in the mapping relationship and sends the parameters to the laser. This mechanism enables the laser to follow and adjust according to real-time speed feedback to adapt to changes in material strip speed. Two-point equation used to calculate power and frequency:

[0101]

[0102] In the formula, is the power or frequency value of the current cycle; The maximum value of the set power or frequency; is the minimum value of the set power or frequency; V f (n) is the effective speed value of the current cycle (i.e., acquisition speed); V max is the maximum value of the set speed; V min The minimum value of the set speed.

[0103] Among them, in some specific application scenarios, before mapping the speed, power and frequency, it is possible to first determine whether the acquisition speed has reached the set node value (determined according to the speed range of the acquisition speed in the previous cycle). If the acquisition speed has not reached the set node value, that is, the acquisition speed has not exceeded the speed range of the previous cycle, then the original laser pulse width can be maintained. Otherwise, the laser power and frequency can be adjusted with the speed through the aforementioned two-point equation mapping.

[0104] 3. Dynamic adjustment of pulse width: The system supports setting several key nodes within the speed range and configuring corresponding pulse width values ​​for each node. Under different pulse widths, dynamic changes in power and frequency can be achieved to adapt to different processing requirements. During the variable speed processing of the material belt, when the system determines that the material belt speed has reached the node value, it will convert the pulse width value configured in the node into the corresponding Laser Mode index, and output the PPI instruction timing to the laser to switch the pulse width of the laser. This dynamic adjustment mechanism can control the peak and average power of the laser, improve frequency stability, accurately adjust the pulse width and repetition frequency, better adapt to the different operating speeds of the material belt, and improve the efficiency and accuracy of laser processing. Figure 4 As shown in the figure, it is a schematic diagram of the pulse width switching protocol timing example. Figure 4 In the example shown, the function enable signal (Pin24) activates the pulse width switching protocol on the rising edge, and the set pulse width will be applied on the falling edge. This signal should be set to a high level for at least 1us before other signals are output, and saved for at least 1us after other signals are output; the latch signal (Pin9) records data on the rising edge, and the minimum period between adjacent latch signals is 1us; the data signal (Pin1-Pin8) sets 8-bit data, the first byte is the prefix 0x05, the second byte is the instruction (the pulse width switching instruction is 0x06), and the third byte is the pulse width index. The data signal should be kept stable for at least 500ns before and after the latch rising edge.

[0105] In summary, the technical solution of the present invention integrates real-time speed monitoring and dynamic adjustment of laser parameters, and accurately applies pulse width control technology, and combines these technologies to achieve accurate response to changes in material speed during laser processing. Specifically, by real-time monitoring of the material speed and dynamically adjusting the laser power and frequency, and accurately controlling the pulse width to adapt to changes in the material speed, the uniform distribution of energy during the processing is ensured, which solves the problem of product quality caused by only being able to use fixed laser parameters for processing when the material speed changes.

[0106] Compared with the prior art, the present invention has at least the following beneficial effects:

[0107] First, the laser equipment introduced into the system in the technical solution of the present invention can be applied to the processing environment where the material belt speed needs to change frequently. The effective speed calculated by the system in real time can ensure that the energy received by the product is uniform and improve the product quality; second, the system in the technical solution of the present invention adds a smoothing filter algorithm in the speed calculation process, which can prevent the speed abnormality caused by the jitter of the encoder output signal, and then prevent the sudden change of related important output quantities, ensuring the stability of the system; third, the system in the technical solution of the present invention achieves accurate response to the change of material belt speed by dynamically adjusting the laser power, frequency and pulse width, thereby improving the accuracy and consistency of processing.
