[0041] Embodiment 1

[0042] Figure 1 This is a flow chart of a control method for a wire feeder of a laser processing device provided in the first embodiment of the present invention. This embodiment can be applied to the case where the MBD development method is used to automatically generate codes instead of handwritten codes. The method can be executed by the control system of the wire feeder of the laser processing device. The control system of the wire feeder of the laser processing device can be implemented in the form of hardware and / or software. The control system of the wire feeder of the laser processing device can be configured in an electronic device with data processing capabilities. Figure 1 As shown, the method includes:

[0043] S110, in response to a triggering operation event on a wire feeder of a laser processing device, determining a target control signal of the wire feeder of the laser processing device.

[0044] The technical solution of the embodiment of the present invention is based on the MATLAB / Simulink tool chain system to carry out functional design, software model construction, digital simulation, automatic code generation, specification integration, software-in-the-loop testing, and continuous multi-task scheduling actual machine testing of the control system of the laser processing device wire feeder, and finally achieves rapid reproduction of traditional code functions, thereby accelerating the development of control strategies for the laser processing device wire feeder. Figure 2 The schematic diagram of the physical structure of a wire feeder of a laser processing device provided in the first embodiment of the present invention. Figure 2 As shown, the wire feeder of the laser processing device mainly includes an embedded processor, a storage, a motor and a peripheral circuit, etc., wherein the peripheral circuit may include a communication bus and a communication interface, etc. Furthermore, this technical solution uses Simulink / Stateflow to replace the original program design and develop new functions, and after simulation verification, automatically generates C code, transforms the interface, integrates it into the existing software, and performs regression testing to ensure the overall consistency and reliability of the software.

[0045] Among them, the operation trigger event may refer to an instruction to control the wire feeder of the laser processing device. Exemplarily, the operation trigger event may be generated by the user operating the control (such as a button or key) in the host computer (i.e., the control system) to control the wire feeder of the laser processing device. For example, the user manually clicks the "retract", "wire filling" or "manual wire feeding" button in the host computer, or it may be a pre-set function signal (which may be one or more). The target control signal can be understood as a control signal corresponding to the operation trigger event. Exemplarily, for the wire filling action, a control signal of 1 indicates that the wire filling action is executed, and a control signal of 0 indicates that the wire filling action is not executed.

[0046] S120, determining a target control requirement of a wire feeder of the laser processing device according to the target control signal.

[0047] In this embodiment, after detecting a user operation event, the target control signal of the laser processing device wire feeder corresponding to the user operation event is first obtained, and then the functional requirements of the laser processing device wire feeder are analyzed according to the target control signal to obtain the target control requirements. Among them, the target control requirements can be understood as the control function requirements of the laser processing device wire feeder, that is, which functions of the laser processing device wire feeder need to be controlled. Optionally, the target control requirements of the laser processing device wire feeder are determined according to the target control signal, including: determining the target control requirements of the laser processing device wire feeder according to a pre-set functional requirement analysis process and the target control signal; wherein the functional requirement analysis process is set based on the preset functions of the laser processing device wire feeder.

[0048] Exemplarily, the preset function may refer to all functions that can be realized by the pre-set wire feeder of the laser processing device, such as motor speed query, light flashing, serial communication, wire feeding, manual wire feeding and parameter verification (specifically parameter verification of serial communication), etc. Among them, light flashing specifically includes LED light on / off / flashing; wire feeding specifically includes wire feeding mode (such as continuous wire feeding, pulse wire feeding), retraction and wire filling; manual wire feeding specifically includes manual wire feeding and manual wire withdrawal. Figure 3 A schematic diagram of a functional requirement analysis process provided in Example 1 of the present invention. Among them, the MyTask function module is used to describe the motor speed query function, the LED_Task function module is used to describe the light flashing function, the Uart_Task function module is used to describe the serial communication function, the Modbus_CRC_Task function module is used to describe the parameter verification function, the WireFeed_Task function module is used to describe the wire feeding function, and the ManualFeed_Task function module is used to describe the manual wire feeding function.

[0049] like Figure 3As shown in the figure, in the functional requirements analysis process, first read the execution result of the last write control system flash, and judge whether the wire feeder of the laser processing device is powered on for the first time based on the execution result. If it is the first power-on, write the initialization parameters to the flash; if it is not the first power-on, directly save the flash storage result. Then create a motor speed query task through the MyTask function module, control the LED flashing through the LED_Task function module, perform serial communication and parameter verification through the Uart_Task function module and the Modbus_CRC_Task function module respectively, control wire feeding through the WireFeed_Task function module, and control manual wire feeding through the ManualFeed_Task function module.

[0050] Specifically, when performing serial communication, the signal quantity is read to determine whether the register is processed, and further determine whether the register needs to be read or written. When controlling wire feeding, first determine whether the current wire feeding mode is continuous wire feeding mode or pulse wire feeding mode according to the target control signal, so as to execute the wire feeding action in the corresponding mode when the wire feeding is enabled. If the current wire feeding mode is pulse wire feeding mode, determine whether the retraction action and wire filling action need to be executed according to the target control signal. When controlling manual wire feeding, first register the button callback function and determine whether the power is on. If it is on, control the LED to light up, and if it is not on, control the LED to go out; then determine whether manual wire feeding and manual wire retraction actions need to be executed according to the target control signal.

[0051] Through such a setting, this scheme utilizes the functional requirement analysis process and target control signals set based on the preset functions that the laser processing device wire feeder can achieve, so as to conduct a rapid and comprehensive demand analysis on the laser processing device wire feeder, thereby determining which functions need to be performed on the laser processing device wire feeder.

[0052] S130, determining a target functional task from a pre-built software control model according to target control requirements.

[0053] In this embodiment, after determining the target control requirements, the target functional tasks can be determined from the pre-built software control model according to the target control requirements. Exemplarily, the software control model can be built based on Simulink. Optionally, the functional tasks include motor speed query tasks, light flashing tasks, serial communication tasks, wire feeding tasks, manual wire feeding tasks, and parameter verification tasks, and these functional tasks correspond one-to-one to the preset functions that can be achieved by the wire feeder of the laser processing device described above. Specifically, a functional task that matches the target control requirements is selected from the various functional tasks of the pre-built software control model as the target functional task.

[0054] In this embodiment, optionally, the software control model adopts a three-layer architecture, which includes a top layer, a structure layer, and a data flow layer. The top layer is used to describe the control functions that can be achieved by the software control model, the structure layer is used to create the functional tasks of the software control model, and the data flow layer is responsible for the business logic implementation of the software control model.

[0055] Figure 4 A schematic diagram of a software control model provided in the first embodiment of the present invention. Figure 4 As shown, the software control model adopts a three-layer architecture of the top layer, the structure layer and the data flow layer. The structure layer is obtained by encapsulating the data flow layer, and the top layer is obtained by encapsulating the structure layer. Specifically, the top layer can be used to describe the control functions that the software control model can achieve. The external manifestation of the top layer is the entire packaged Controller, which only displays the signal input interface Input and the signal output interface Output to the outside, that is, the MBD_User_Task in the top layer is the encapsulation of each functional task in the structure layer. The structure layer is also an intermediate layer, which is composed of the same functional tasks. The structure layer can be nested at multiple levels, and multiple functional tasks can be nested inside the functional tasks. Exemplarily, the wire feeding mode, retraction and wire filling functional tasks can be nested inside MBD_WireFeed_Task, and the manual wire feeding and manual wire retraction functional tasks can be nested inside MBD_ManualFeed_Task. The data flow layer is the bottom layer, which is responsible for the specific business logic implementation through task scheduling, and is built using the basic function library in MATLAB / Simulink.

[0056] Through such a setting, this solution can quickly build a control system algorithm prototype. The software control model designed with a three-layer architecture can achieve program reusability, thereby improving software development efficiency and software version update speed, making it easier to quickly adjust software services according to changes in demand.

[0057] S140, controlling the wire feeder of the laser processing device based on the software execution result of the target functional task.

[0058] In this embodiment, after the target functional task is determined, the target functional task can be executed through task scheduling, and the wire feeder of the laser processing device can be controlled based on the software execution result of the target functional task. Optionally, the wire feeder of the laser processing device is controlled based on the software execution result of the target functional task, including: converting the software execution result into a data format to obtain hardware control information; and controlling the wire feeder of the laser processing device according to the hardware control information.

[0059] It should be noted that the laser processing device wire feeder cannot directly recognize the software execution result, so it is necessary to convert the software execution result into a data format to obtain hardware control information that the laser processing device wire feeder can recognize. Then the hardware control information is sent to the laser processing device wire feeder, and the laser processing device wire feeder can be controlled according to the hardware control information.

[0060] The technical solution of the embodiment of the present invention determines the target control signal of the wire feeder of the laser processing device in response to the trigger operation event of the wire feeder of the laser processing device; determines the target control requirement of the wire feeder of the laser processing device according to the target control signal; determines the target functional task from the pre-built software control model according to the target control requirement; and controls the wire feeder of the laser processing device based on the software execution result of the target functional task. This technical solution uses the MBD development method to automatically generate code instead of handwritten code, which reduces manual coding errors and improves coding quality; by describing the behavior and structure of the control system through the constructed software control model, the control system algorithm prototype can be quickly built, which can effectively improve the development efficiency of the control system and the software iteration speed; the software control model can verify the correctness of the algorithm at an early stage through simulation, reduce design defects, and enhance the stability and reliability of the control system.

[0061] In this embodiment, optionally, the method further includes: in the process of constructing the software control model, batch establishing and setting the interface properties of the software control model by calling the target data dictionary; wherein the target data dictionary is predetermined based on the hardware configuration of the wire feeder of the laser processing device.

[0062] It should be noted that when the structure of the software control model is complex and contains thousands of signals and parameters, the manual creation and configuration of the property dialog box is very labor-intensive, resulting in low efficiency of property configuration. Therefore, in order to improve the configuration efficiency of the interface properties of the software control model, a data dictionary management can be created in the Simulink model, an M script can be written in the MATLAB language, and the data in the target data dictionary (predetermined based on the hardware configuration of the wire feeder of the laser processing device) can be automatically imported for batch processing. When the M script is completed, all information in the target data dictionary is automatically imported into the basic workspace of MATLAB and created as a data object. Exemplarily, the target data dictionary can be represented in the form of an Excel table. Among them, the control of data through Excel tables has the advantages of flexibility and freedom, and parameter configuration can be edited without the need for a MATLAB environment, thereby improving the management and maintenance efficiency of the target data dictionary.

[0063] In this embodiment, optionally, the target data dictionary includes a first data type, a second data type, and a third data type, the first data type is used to describe semaphore attributes, the second data type is used to describe parameter attributes, and the third data type is used to describe bus data types.

[0064] In this embodiment, an Excel table can be used as the basis for establishing a data dictionary. Specifically, an Excel table including three groups (Sheet1, Sheet2 and Sheet3) is pre-created as a target data dictionary for distinction and management. Among them, Sheet1 is used to store the first data type (used to describe semaphore properties); Sheet2 is used to store the second data type (used to describe parameter properties); Sheet3 is used to store the third data type (used to describe bus data type). Among them, the semaphore can be understood as a variable, and the parameter can be understood as a fixed quantity. Exemplarily, the bus data type can be a floating point type, a double precision type, an array, etc.

[0065] Figure 5 A flowchart of automatically importing data in a target data dictionary through an M script is provided in the first embodiment of the present invention. Figure 5 As shown, first clear the command line window and workspace content of MATLAB, then read the signal data through the table, create a signal object, and store the signal object in the basic workspace of MATLAB. Specifically, get the semaphore data from the table Sheet1; traverse the data content to get the signal name; automatically set the signal properties; process the initial value, get the data, convert it into a string and a character vector; store the signal object in the basic workspace. Then read the parameter data through the table, create a parameter object, and store the parameter object in the basic workspace of MATLAB. Specifically, read the parameter data content in the table Sheet2; create a parameter object, get the parameter name, get the parameter data; set the parameter quantity properties, and store the parameter object in the basic workspace. Finally, get the table structure data; get the unique Bus name, use the dot symbol to access the column; and create a Bus object and store it in the basic workspace of MATLAB; pre-allocate the Bus element array. Specifically, traverse all elements of the current Bus, get the element name, get the data type, get the minimum value, get the maximum value, get the unit, parse the dimension, get the data and convert it into a numeric array, ensure conversion into a numeric array, set the dimension, add the element to the Bus element array; create a Bus object; store the Bus object in the basic workspace.

[0071] S230, determining a target functional task from a pre-built software control model according to target control requirements.

[0072] Exemplarily, the software control model can be constructed based on Simulink.

[0075] In order to verify the effectiveness of this technical solution, the following three working conditions of the wire feeder of the laser processing device are used to draw the motor duty cycle curves of the handwritten code and the MBD code, and further obtain the comparison result diagram and tolerance analysis diagram of the motor duty cycle curve, so as to compare and analyze the control effects of the handwritten code and the MBD code. Among them, the three working conditions are wire feeding working condition, retraction working condition and wire filling working condition.

Fig. 7A and Figure 7B As can be seen from the figure, the motor duty cycle curves of the handwritten code and the MBD code Figure 1 The comparison results are consistent, and the tolerance value is 0, which proves that MBD development can completely reproduce the wire feeding function of the traditional handwritten code of the wire feeder of the laser processing device.
