Description

Technical Field

[0001] This disclosure relates to the field of laser processing technology, and more specifically to a data transmission method for a laser processing system. Background Technology

[0002] In laser processing systems, especially in high-speed processing applications using galvanometer scanning, the processing trajectory is usually composed of a large amount of continuous control data. During the processing, the processing data needs to be continuously transmitted to the control unit and executed in real time, which places high demands on the continuity and stability of data transmission.

[0003] Processing data is typically generated by a higher-level control system and transmitted to a lower-level control unit via fieldbus or industrial Ethernet. The lower-level control unit then performs data buffering, processing, and execution control. However, due to the inconsistent processing rhythms between data generation, data transmission, and processing execution, problems such as buffer congestion, data overwriting, or data loss can easily occur in continuous, large-scale data transmission scenarios, thereby affecting the continuity of galvanometer motion and processing stability. Summary of the Invention

[0004] In view of the above problems, this disclosure provides a data transmission method for a laser processing system based on the coordinated transmission of data using double buffering and ring buffering.

[0005] This disclosure provides a data transmission method for a laser processing system, comprising: generating processing data of the laser processing system according to the parameters of the laser processing system and a preset processing task; receiving the processing data in an alternating manner through multiple receiving buffers, wherein at any given time, only one receiving buffer is in a writable state, and the other receiving buffers are in a readable state; writing the processing data in the receiving buffer in the readable state into sequentially arranged storage units, wherein the sequentially arranged storage units are provided with write pointers and read pointers, and the write pointers and read pointers automatically return to the beginning when they reach the end of the storage unit sequence; reading the processing data from the sequentially arranged storage units and processing it to drive the laser processing system to perform processing.

[0006] According to embodiments of this disclosure, receiving processed data in an alternating manner through multiple receive buffers includes: switching the state of a receive buffer currently in a writable state to a readable state in response to the buffer being full; and using a buffer pointer to specify the next receive buffer to switch to a writable state in a preset order, wherein the buffer pointer is used to indicate the receive buffer currently in a writable state.

[0007] According to an embodiment of this disclosure, writing processed data in a readable receive buffer into sequentially arranged storage units includes: monitoring the available space of the sequentially arranged storage units; pausing or reducing the writing of new processed data into the readable receive buffer in response to the available space being lower than a first preset threshold; and resuming the writing of new processed data into the readable receive buffer in response to the available space recovering to above the first preset threshold.

[0008] According to embodiments of this disclosure, receiving processing data in an alternating manner through multiple receiving buffers further includes: when the occupancy status of sequentially arranged storage units meets preset conditions, prohibiting the switching between write and read states of the multiple receiving buffers, and / or prohibiting the writing of new processing data to the receiving buffer currently in a write state; wherein the preset conditions include at least one of the available space of sequentially arranged storage units being lower than a second preset threshold and a laser processing system malfunction, and the first preset threshold being greater than the second preset threshold.

[0009] According to embodiments of this disclosure, the processed data in the receive buffer in a readable state is written into sequentially arranged storage units, and before that, the process further includes: performing an integrity check on the processed data in the receive buffer in a readable state.

[0010] According to embodiments of this disclosure, processing data is read from sequentially arranged storage units and processed to drive a laser processing system to perform processing. The method further includes generating a processing completion confirmation signal in response to the laser processing system completing a processing segment based on the processing data read from the storage units.

[0011] According to an embodiment of this disclosure, writing processed data in a readable receive buffer into sequentially arranged storage units includes: in response to receiving a processing completion confirmation signal, marking the storage unit corresponding to the processing completion confirmation signal as idle; and in response to the storage unit pointed to by the write pointer being idle, writing the processed data in the readable receive buffer into the storage unit.

[0012] The second aspect of this disclosure provides a data transmission system for a laser processing system, capable of implementing the aforementioned data transmission method for the laser processing system, comprising: a data generation module for generating processing data of the laser processing system based on parameters of the laser processing system and a preset processing task; a data transmission module for receiving processing data in an alternating manner through multiple receiving buffers, wherein at any given time, only one receiving buffer is in a writable state, while the other receiving buffers are in a readable state, and the processing data in the receiving buffer in the readable state is written into sequentially arranged storage units, the sequentially arranged storage units being provided with write pointers and read pointers, the write pointers and read pointers automatically returning to the beginning when they reach the end of the storage unit sequence; and a data processing module for reading processing data from the sequentially arranged storage units and processing it to drive the laser processing system to perform processing.

[0014] A fourth aspect of this disclosure also provides a computer-readable storage medium having executable instructions stored thereon, which, when executed by a processor, cause the processor to perform the data transmission method of the laser processing system described above.

[0015] According to the data transmission method of the laser processing system provided in this disclosure, a buffer architecture is established by setting up multiple receiving buffers for alternating reception and sequential storage units with circular pointers. Since the multiple receiving buffers ensure the continuity of the data reception process and prevent interruptions due to waiting for data transfer, and the sequential storage units with circular pointers act as large-capacity queues, decoupling the data reception process from the processing execution process, this method at least partially solves the technical problem of data reception blockage caused by the mismatch between data generation speed and processing execution speed in large-scale laser processing data transmission, achieving a smooth and stable data flow.

[0019] The embodiments of the present disclosure will now be described with reference to the accompanying drawings. However, it should be understood that these descriptions are exemplary only and are not intended to limit the scope of the disclosure. In the following detailed description, numerous specific details are set forth to provide a thorough understanding of the embodiments of the present disclosure for ease of explanation. However, it will be apparent that one or more embodiments may be practiced without these specific details. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concepts of the present disclosure.

[0020] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit this disclosure. The terms “comprising,” “including,” etc., as used herein indicate the presence of the stated features, steps, operations, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, or components.

[0021] All terms used herein (including technical and scientific terms) have the meanings commonly understood by those skilled in the art, unless otherwise defined. It should be noted that the terms used herein are to be interpreted in a manner consistent with the context of this specification, and not in an idealized or overly rigid way.

[0022] When using expressions such as "at least one of A, B and C", they should generally be interpreted in accordance with the meaning that is commonly understood by those skilled in the art (e.g., "a system having at least one of A, B and C" should include, but is not limited to, a system having A alone, a system having B alone, a system having C alone, a system having A and B, a system having A and C, a system having B and C, and / or a system having A, B and C, etc.).

[0023] Some existing technologies use a single cache or simple queue to temporarily store processed data, or increase cache capacity to alleviate data congestion. However, in high-speed processing scenarios, these methods still struggle to ensure continuous data reception while maintaining stable scheduling of the data execution process. Furthermore, although some systems have introduced dual-buffer or ring-buffer structures, these are mostly used independently and lack mechanisms for coordinating and controlling the processing progress, resulting in issues such as untimely buffer switching or insufficient storage space.

[0024] Therefore, existing laser processing systems urgently need a technical solution that can coordinate the data reception, buffering, and execution rhythm during continuous processing to improve the stability and reliability of the system under large-scale processing data transmission conditions.

[0025] Figure 1 A flowchart illustrating a data transmission method of a laser processing system according to an embodiment of the present disclosure is shown, such as... Figure 1As shown, embodiments of this disclosure provide a data transmission method for a laser processing system used for large-scale processing data transmission and scheduling control in a laser processing system. The method includes: generating processing data for the laser processing system based on parameters and preset processing tasks; receiving the processing data in an alternating manner through multiple receiving buffers, wherein at any given time, only one receiving buffer is in a writable state, while the other receiving buffers are in a readable state; writing the processing data in the readable receiving buffers into sequentially arranged storage units, each storage unit having a write pointer and a read pointer, the write pointer and read pointer automatically returning to the beginning when they reach the end of the storage unit sequence; and reading the processing data from the sequentially arranged storage units and processing it to drive the laser processing system to perform processing.

[0026] The write pointer indicates the location where the processed data is written, and the read pointer indicates the location where the processed data is read, so as to support the cyclic writing and reading of processed data.

[0027] In this embodiment, the sequentially arranged storage units are implemented using an array and two indices (read pointer and write pointer). When the pointer reaches the end of the array, a modulo operation is used to return it to the beginning, thus forming a circular buffer storage unit, supporting the circular writing and reading of processed data within the circular buffer storage unit. The sequentially arranged storage units can be physically sequentially stored, or logically sequentially structured by data structures such as linked lists.

[0028] Through the embodiments of this disclosure, existing laser processing systems address issues such as large data volume, continuous data input, and inconsistent data processing rhythms during processing. Particularly between multiple stages, including correction data generation, processing data transmission, and processing execution, insufficient data caching and unreasonable scheduling mechanisms can easily lead to data loss, system congestion, or processing instability. By introducing a double-buffer structure and a ring-buffer structure into the laser processing system, and scheduling and controlling the data reception rhythm based on the ring-buffer's occupancy status, coordinated matching between the processing data reception process and the processing execution process is achieved. This ensures stable data caching capabilities even under continuous, large-scale data transmission scenarios, improving the data transmission stability and processing reliability of the laser processing system, and avoiding processing anomalies caused by data congestion or processing delays.

[0029] Based on the above embodiments, the method further includes: acquiring the motion parameters and / or optical parameters of the laser processing system before laser processing begins, and generating corresponding correction data based on the acquired parameters. The correction data is used to compensate for spatial position, motion errors, or optical deviations in subsequent processing to ensure consistency between the processing data and the actual processing system. Based on this, processing data is generated according to the correction data and a preset processing task. This processing data describes the control information of the laser, galvanometer system, and / or motion mechanism during laser processing. The specific implementation of the correction can employ visual correction or other existing correction methods according to actual application requirements; this embodiment does not limit this approach.

[0030] Based on the above embodiments, the processing data is received in an alternating manner through multiple receive buffers, including: in response to the current writeable receive buffer being full, switching its state to readable; using a buffer pointer, specifying the next receive buffer to switch its state to writeable in a preset order, wherein the buffer pointer is used to indicate the receive buffer currently in writeable state.

[0031] Optionally, the multiple receive buffers are dual-buffered receive units, including a first receive buffer and a second receive buffer. The first receive buffer and the second receive buffer are used to receive processed data in an alternating manner, wherein at any given time only one receive buffer is in the data writing state, and the other receive buffer is in the readable state.

[0032] Furthermore, the processed data in the receive buffers that are in a readable state among the multiple receive buffers is written into the storage unit sequence. After the writing is completed, the receive buffer is switched to a data writing state for receiving subsequent processed data. The preset order is not limited to simple polling; it can be a scheduling based on buffer priority, prioritizing the switch to the buffer with the longest idle time.

[0033] The embodiments of this disclosure avoid read-write conflicts during data reception. Processed data in the readable receive buffer is written into the circular buffer storage unit to achieve continuous caching of processed data.

[0034] Based on the above embodiments, writing the processed data in the receive buffer that is in a readable state into sequentially arranged storage units includes: monitoring the available space of the sequentially arranged storage units; pausing or reducing the writing of new processed data into the receive buffer that is in a writable state in response to the available space being lower than a first preset threshold; and resuming the writing of new processed data into the receive buffer that is in a writable state in response to the available space recovering to be higher than the first preset threshold.

[0035] In this embodiment, the occupancy status of the ring buffer storage unit is monitored, and the data reception rhythm of the double-buffered receiving unit is controlled according to the occupancy status. When the available storage space of the ring buffer storage unit is lower than a preset threshold, the data reception of the double-buffered receiving unit is paused or reduced; when the available storage space of the ring buffer storage unit recovers to above the preset threshold, the data reception of the double-buffered receiving unit is resumed, thereby avoiding data loss or system blockage due to insufficient buffer space.

[0036] Through the embodiments of this disclosure, the speed at which new data is written to the receive buffer is dynamically adjusted based on the available space status of the ring buffer. When the downstream processing is slow and the ring buffer is about to fill up, the data supply rate of the upstream data source is reduced, thereby achieving flow control. It can dynamically adjust the input data stream according to its own real-time processing capabilities.

[0037] Based on the above embodiments, receiving processing data in an alternating manner through multiple receiving buffers further includes: when the occupancy status of the sequentially arranged storage units meets preset conditions, prohibiting the switching between the write state and the read state of the multiple receiving buffers, and / or prohibiting the writing of new processing data to the receiving buffer currently in the write state; wherein, the preset conditions include at least one of the available space of the sequentially arranged storage units being lower than a second preset threshold and a laser processing system malfunction, and the first preset threshold being greater than the second preset threshold.

[0038] In this embodiment, if the available space of the sequentially arranged storage units is lower than a second preset threshold when the preset trigger condition is triggered, then when the available space is greater than the second preset threshold, the state switching of the multiple receive buffer and data writing are restored; if the preset trigger condition is triggered by a system failure, then data writing is restarted through manual review.

[0039] Through the embodiments of this disclosure, when the occupancy status of the ring buffer storage unit meets the preset scheduling conditions, buffer switching can be prohibited, and / or writing new processing data to the receiving buffer currently in the data writing state can be prohibited, so as to achieve further scheduling control of the data receiving rhythm. When the system is close to complete congestion or an anomaly occurs, adjusting the upstream speed alone is insufficient to ensure system stability, and it is necessary to immediately interrupt the data inflow. The data flow can be dynamically adjusted according to the real-time operating status of the system to improve the operational stability of the laser processing system in large-scale, continuous data transmission scenarios.

[0040] Based on the above embodiments, the processed data in the receive buffer that is in a readable state is written into the sequentially arranged storage units, and before that, the integrity of the processed data in the receive buffer that is in a readable state is verified.

[0041] Through embodiments of this disclosure, erroneous data is intercepted early in the data transmission link, preventing erroneous data from causing processing errors.

[0042] Based on the above embodiments, processing data is read from sequentially arranged storage units and processed to drive the laser processing system to perform processing. The method further includes generating a processing completion confirmation signal in response to the laser processing system completing a processing segment based on the processing data read from the storage units.

[0043] Through the embodiments of this disclosure, a processing completion confirmation signal is generated after processing is executed, binding the release of data resources with the actual completion of physical processing, thereby achieving synchronization between data production and consumption, and solving the data overwrite problem caused by asynchronous processing rhythms between upstream and downstream processes.

[0044] Based on the above embodiments, writing the processed data in the receive buffer that is in a readable state into sequentially arranged storage units includes: in response to receiving a processing completion confirmation signal, marking the storage unit corresponding to the processing completion confirmation signal as idle; and in response to the storage unit pointed to by the write pointer being in an idle state, writing the processed data in the receive buffer that is in a readable state into the storage unit.

[0045] Through the embodiments of this disclosure, the operation of writing data to a storage unit is configured to simultaneously satisfy two conditions: receiving a processing completion confirmation signal for a specific storage unit and the storage unit pointed to by the write pointer being in an idle state. This constitutes a handshake mechanism, ensuring the security of data writing.

[0046] Based on the above embodiments, the method further includes: driving the galvanometer system to complete the laser processing operation according to the processed processing data. Processing data is read sequentially from the storage unit sequence and converted into control instructions executable by the galvanometer system, thereby achieving continuous execution of the processing trajectory. The specific control method for the laser processing operation can be set according to the type of galvanometer system and the control strategy; this embodiment does not further limit this.

[0047] Figure 2 A data transmission block diagram according to an embodiment of the present disclosure is illustrated schematically, such as... Figure 2 As shown, in this embodiment, the processing data is generated in batches by the host computer according to a preset data format. Each batch contains a fixed length of data and is sent to the STM32H7 chip, which serves as the control unit, via the EtherCAT bus. The processing data is transmitted in the form of a continuous data stream, and each batch of processing data logically corresponds to a continuous processing trajectory or control command sequence. Data transmission and processing are implemented by the lower-level control unit, which can use an STM32H7 series microcontroller to perform functions such as double-buffered reception, ring buffer storage, and data scheduling control.

[0048] At the initial time t0, the host computer sends the first batch of processing data, data 1. After receiving data 1, the STM32H7 writes it into the first receive buffer (Buffer 0) in the double-buffered receive unit. During the data writing process to Buffer 0, the STM32H7 microcontroller performs integrity checks on the received data, such as verifying the data content through Cyclic Redundancy Check (CRC) to ensure that the data written to the buffer is valid and that no transmission errors have occurred.

[0049] While Buffer 0 is not yet full, subsequent data from the host computer (PC) continues to be written to Buffer 0. When the data buffered in Buffer 0 meets the full condition, the STM32H7 switches the state of Buffer 0 from "write state" to "read state" and simultaneously switches the double-buffered receiving unit to the second receiving buffer (Buffer 1) to enter the data writing state. At this time, the next batch of processed data, data 2, sent by the host computer, is written to Buffer 1, thus ensuring that the data receiving process is uninterrupted.

[0050] While Buffer 1 receives data2, the STM32H7 writes the data in the readable Buffer 0 into the circular buffer storage unit. The circular buffer storage unit consists of multiple sequentially arranged storage units, with a write pointer indicating the current write position, and stores the processed data from Buffer 0 sequentially in a circular manner. This method achieves parallel cooperation between the dual-buffered receiving unit and the circular buffer storage unit: on the one hand, it continuously receives data from the host computer, and on the other hand, it transfers the received data to the circular buffer for subsequent processing.

[0051] As the processing progresses, the processing data in the annular buffer storage unit is retrieved sequentially by the execution module to drive the galvanometer system to complete the corresponding processing operations. In this embodiment, the annular buffer storage unit organizes data in multiple slots, with each slot storing a batch of processing data or its segments. After the execution module completes reading the processing data in the current slot and executing the galvanometer, it marks the corresponding slot as released, making the slot writable again.

[0052] Meanwhile, the system confirms the completion status of the previous batch of processing data. Once the execution module has finished processing the previous batch of data and successfully released the corresponding slot, it sends an ACK2 confirmation message to the STM32H7, indicating that the previous batch of processing data has been completed and that a usable slot has been released in the ring buffer storage unit. Upon receiving ACK2, the STM32H7 allows the next batch of double-buffered and verified processing data to be written into the free slot of the ring buffer storage unit.

[0053] Through the above method, an ACK2-based handshake relationship is established between slot release and new data writing in the ring buffer storage unit. This ensures that processing data is only allowed to enter the ring buffer storage unit after the execution module has completed the previous batch of data and released storage resources, thereby preventing data overwriting before processing is completed. Simultaneously, this handshake mechanism ensures that the ring buffer always contains subsequent data available for reading during the continuous processing of data by the galvanometer system, achieving continuity of galvanometer movement and stability of the processing process.

[0054] Based on the same inventive concept, this disclosure also provides a data transmission system for a laser processing system, which can be used to implement the aforementioned data transmission method for the laser processing system, including: a data generation module, used to generate processing data of the laser processing system according to the parameters of the laser processing system and the preset processing task; a data transmission module, used to receive processing data in an alternating manner through multiple receiving buffers, wherein at any given time, only one receiving buffer is in a writable state, and the other receiving buffers are in a readable state, and the processing data in the receiving buffer in the readable state is written into sequentially arranged storage units, the sequentially arranged storage units are provided with write pointers and read pointers, and the write pointers and read pointers automatically return to the beginning when they reach the end of the storage unit sequence; and a data processing module, used to read the processing data from the sequentially arranged storage units and process it to drive the laser processing system to perform processing.

[0055] Based on the above embodiments, a calibration module is also included, used to acquire the motion parameters of the laser processing system and generate corresponding calibration data; a processing execution module is used to drive the laser and complete the laser processing based on the processed processing data. The modules are connected and work collaboratively according to the data flow direction during the laser processing, thereby forming a complete data generation, transmission, processing, and execution system.
