[0037] Figure 1 This is a flowchart illustrating a multi-servo control method based on XML configuration and OPC UA communication, provided as an embodiment of the present invention. This embodiment is applicable to a multi-servo human-machine interaction control system for tobacco packaging equipment. The method can be executed by a multi-servo control device based on XML configuration and OPC UA communication. This device can be implemented in hardware and / or software and can be configured in any electronic device with communication capabilities. See also... Figure 1 The method includes:

[0038] S110. Based on a pre-built multi-source XML configuration file, a set of servo objects is generated through association and matching using a unified identifier field.

[0039] The servo object set is a standardized software entity set generated in the host computer software, with a single servo motor as the smallest unit. After XML configuration parsing and unified identification association integration, each servo object fully encapsulates the communication address, operating parameters, control interface, group attributes, and device identification information of a single servo. All servo objects in the set together constitute the single core data carrier for host computer monitoring, control, interface generation, and group filtering.

[0040] Specifically, the system pre-builds at least two types of XML configuration files for servo status monitoring and servo control functions, respectively. Each type of XML configuration file contains a unified identifier field as a unique association key. Upon startup, the host computer parses all XML configuration files, using the unified identifier field as the matching basis to automatically associate and integrate the scattered configuration information such as status parameter nodes, control function addresses, grouping information, and device affiliation corresponding to the same servo motor. Ultimately, a complete software data object is generated for each servo motor, and all servo data objects together constitute a servo object set, achieving structured and scalable modeling of the multi-servo system. This step, through XML configuration file parsing and servo object mapping mechanisms, automatically integrates scattered configuration data into a unified servo object set, enabling dynamic expansion of the number of servos while avoiding manual configuration one by one, thus improving system initialization efficiency and consistency.

[0041] S120. Perform a batch read operation on the set of servo node addresses in the set of servo objects through the OPC UA client to obtain servo motor running data and perform caching and concurrent control.

[0042] The servo node address set is a collection of OPC UA communication addresses extracted from multi-source XML configuration files, associated with a unified identifier, and aggregated. It is a built-in attribute of the servo object collection. Operational data includes position, speed, current, temperature, torque, error values, and status information.

[0043] Specifically, the host computer relies on the OPC UA communication client to retrieve the OPC UA servo node addresses encapsulated within each servo object in the servo object set, and performs batch concurrent read operations on all node addresses; through this communication operation, it collects real-time operating data such as the position, speed, current, temperature, and faults of the servo motor; the system stores the collected real-time operating data into a preset cache structure, and ensures the consistency and security of data reading and writing under multi-threading through a concurrency control mechanism, providing unified data support for subsequent interface display, status monitoring, and control operations.

[0044] During data communication, based on the servo node address set parsed from the XML configuration file, multiple address index arrays categorized by data type are constructed. Batch read operations are then performed on the servo node address set via the OPC UA client interface to obtain various data types, including real-time position, speed, current, temperature, torque, error values, and status information of the servo motor. According to preset configuration conditions, selectively enabling the reading of certain servo status data (including enable status, fault status, and reference position) is implemented to adapt to different models or functional requirements. During data processing, a data caching structure is set up in conjunction with a concurrency control mechanism to uniformly store and update the batch-read data, thereby ensuring data consistency and access security in a multi-threaded environment. Through these methods, efficient data acquisition and centralized management of multiple servo systems are achieved, reducing communication overhead and improving the system's response performance and stability in large-scale servo scenarios. Among them, the preset configuration conditions refer to the data reading filtering rules that are pre-configured in the multi-source XML configuration file. Based on the differences in the model of the tobacco packaging equipment, functional requirements or debugging scenarios, the rules pre-set the data types of servo status that need to be read and the range of servo motors, so as to selectively collect specified data such as servo enable status, fault status, and reference position, and block the reading of unnecessary data.

[0045] S130: Based on the pre-built servo operation interface module, data binding and control command issuance are completed according to the servo object set, and a multi-level servo display interface is generated using a unified interface template.

[0046] The system includes a servo operation interface module, a motor monitoring module, a motion controller monitoring module, a motor brake control module, a motor positioning module, a current parameter monitoring module, and a motor manual control module. The motor monitoring module centrally displays the operating status information of each servo motor and provides grouping and filtering functions based on device location. The motion controller monitoring module displays the controller's operating status. The motor brake control module performs single-motor brake control operations. The motor positioning module sets the motor's reference position. The current parameter monitoring module monitors relevant parameters of the motor's operating current. The motor manual control module allows for manual adjustment and control of the motor and supports multi-level precision selection.

[0047] Specifically, the host computer pre-builds standardized servo operation interface modules divided by function. The system uses a set of servo objects as the core data carrier, and bidirectionally binds the servo operation interface modules with the real-time running data and control addresses within the servo object set. When operators trigger control operations through the interactive interface, the system automatically generates control commands based on the binding relationship and sends them to the underlying devices. Simultaneously, the system calls a unified interface template, combined with the configuration information of the servo object set, to automatically generate a servo monitoring display interface with multi-level classification capabilities, eliminating the need for independent interface development for each servo. Control commands are implemented by writing to the corresponding nodes via OPC UA. By dividing the servo operation interface modules by function and uniformly managing multiple servo objects in each module, the number of interface jumps is reduced, operation path efficiency is improved, and data consistency between status data and control operations is ensured. Based on the servo object set, a unified interface template is used to automatically generate multi-level servo display interfaces and control units, and the interface controls are bound to the servo object data. The interface is modularly divided according to function, with different functions corresponding to different interface modules. Each interface module displays all relevant data or control items for all servo motors. By using template reuse and data-driven interface generation, the interface can automatically expand with the number of servos, avoiding the need to develop a separate interface for each motor, greatly reducing development complexity, while ensuring a unified interface style and data consistency.

[0048] S140. Construct grouping mapping relationships through the grouping identifier field in the XML configuration file, and configure filtering control components in the servo display interface at each level to achieve classified display and rapid positioning of servo motors in the servo object set.

[0049] Specifically, the host computer reads the predefined group identifier field in the XML configuration file and establishes a group mapping relationship between servo motors and equipment parts, controllers, and unit affiliations. The system integrates a filtering control interaction component in the dynamically generated servo display interfaces at each level. Through this filtering component, operators can filter all servo motors in the servo object set according to the group dimension, and only display the servo data within the target group, thereby realizing hierarchical classification display of large-scale multi-servo motors and rapid location of faults and target equipment.

[0050] By utilizing group identifier fields defined in the XML configuration file (such as group_code, machine_code, servoController, etc.), a multi-dimensional grouping mechanism is constructed. Filtering control components based on device location are provided in various functional interfaces for rapid filtering and display of servo motors. By establishing multi-level grouping mapping relationships, rapid classification and location of multiple servo devices are achieved, enabling operators to quickly locate the target device among a large number of servos, significantly improving operational efficiency.

[0051] The technical solution provided by this invention generates a set of servo objects based on a pre-built multi-source XML configuration file through unified identifier field association and matching, achieving integrated management of all servo information and eliminating the problems of information dispersion and multi-source fragmentation at the data level. Through an OPC UA client, batch read operations are performed on the set of servo node addresses in the set of servo objects to obtain servo motor operating data, which is then cached and concurrently controlled. Servo status data scattered across different controllers is centrally acquired and updated, eliminating the need for separate data reading for different pages and channels, and avoiding switching between multiple pages for data retrieval. Based on a pre-built servo operation interface module, data binding and control command issuance are completed according to the set of servo objects. A multi-level servo display interface is generated using a unified interface template, integrating status monitoring and control operations into the same functional module. All servos can be centrally monitored and operated within the same module, eliminating the need to switch between different independent interfaces to view different servos, and completely eliminating the operation path of frequent switching between multiple pages. Grouping mapping relationships are constructed using grouping identifier fields in XML configuration files, and filtering control components are configured in the servo display interfaces at each level to achieve categorized display and rapid location of servo motors within the servo object set. Operators can directly filter target groups to quickly locate target motors and malfunctioning devices among a large number of servos without traversing all servos or switching pages to search. The technical solution provided by this invention can effectively improve the status monitoring efficiency of multi-servo systems.

[0052] Figure 2 This is a flowchart illustrating another multi-servo control method based on XML configuration and OPC UA communication provided by an embodiment of the present invention. This embodiment further refines the aforementioned embodiments. See also... Figure 2 Optionally, S110 specifically includes:

[0053] S210. Construct a multi-source XML configuration file to perform structural decoupling modeling of the multi-servo control system. The host computer parses the multi-source XML configuration file and generates a set of servo objects by associating and matching them through a unified identifier field.

[0054] Specifically, at least two types of XML configuration files are constructed to perform structural decoupling modeling of the multi-servo control system; the XML configuration files are read and associated through unified identifier fields to generate a set of servo objects.

[0055] The two types of XML configuration files include status monitoring XML and control function XML. The status monitoring XML is used to define the mapping relationship between servo motor operating status parameters and OPC UA nodes, including the corresponding OPC UA nodes (NodeId) for position, speed, current, temperature, alarm codes, etc. The control function XML is used to define servo control function parameters, including brake control address, set address, jog control address and related function identifiers. It also uniformly configures motor coding, grouping information, device affiliation and controller number.

[0056] By configuring the status data and control functions of the servo system in a structured manner and associating them with a unified identifier, decoupled modeling of multiple servo systems is achieved, enabling the system to have good scalability and cross-model reuse capabilities, and avoiding the maintenance complexity problems caused by traditional hard-coding methods.

[0057] Optionally, S120 specifically includes:

[0058] S220: Based on the servo node address set obtained by parsing the multi-source XML configuration file, the OPC UA client performs a batch read operation on the servo node address set to obtain servo motor running data and perform caching and concurrent control.

[0059] Specifically, the host computer software parses the pre-built multi-source XML configuration file, extracts and summarizes the OPC UA communication node addresses corresponding to all servo motors, forming a servo node address set; the system calls the OPC UA communication client to perform a one-time batch data read operation on all node addresses in the address set, collecting real-time operating data such as the position, speed, current, and faults of the servo motors; at the same time, the system builds a data cache structure to uniformly store the collected operating data, and uses a concurrency control mechanism to ensure the consistency and security of data reading and writing in a multi-threaded operating environment, providing stable data support for subsequent interface monitoring and control operations.

[0060] The technical solution provided by this invention involves embedding grouping attributes such as tobacco packaging location and equipment affiliation into an XML configuration file on a host computer. A unified identifier field is used to integrate and match the grouping information with the identity and communication address of the servo motor, generating a structured set of servo objects. This set provides modular and grouped structured encapsulation of the servo motors at the data level, replacing the fragmented and undifferentiated data organization of existing technologies. Each servo motor possesses standardized grouping attributes, eliminating the defects of unmodularized and chaotic servo information at the data source. This provides a structured data foundation for the orderly display of data, fundamentally improving the problems of information density and poor readability. Through multi-source XML configuration, decoupling modeling of status data and control functions is achieved, generating a unified and standardized set of servo objects and establishing a structured data model adaptable to multiple servo scenarios. This replaces the fragmented and irregular data organization methods of existing technologies, providing a unified and reusable data mapping carrier for the host computer interface and solving the problem of inefficient data mapping caused by the lack of a structured data model. Based on the structured servo node address set obtained by XML parsing, the system centrally collects servo operation data using OPC UA batch reading and achieves unified data storage and management through caching and concurrency control. This replaces the traditional single-point scattered data acquisition method, realizing centralized and efficient acquisition and reuse of multi-servo data, greatly improving data utilization efficiency in multi-servo scenarios, and eliminating the technical defects of scattered data and inefficient access.

[0061] Figure 3 This is a flowchart illustrating another multi-servo control method based on XML configuration and OPC UA communication provided by an embodiment of the present invention. This embodiment further refines the aforementioned embodiments. See also... Figure 3 Optionally, following S140, the following also includes:

[0062] S310. When a user selects a servo motor, the corresponding device location diagram is matched based on the servo motor's identification information to complete the spatial location visualization linkage.

[0063] Specifically, when an operator selects any servo motor on the human-machine interface, the system obtains the unified identification information corresponding to that servo motor. Using this identification information as the retrieval basis, the system automatically matches the pre-configured equipment location association information of the servo motor in the servo object set and retrieves the equipment location diagram corresponding to the servo motor's installation location. This diagram is then displayed in a designated area on the interface, intuitively presenting the physical installation location and spatial affiliation of the servo motor within the tobacco packaging equipment. This achieves a visual linkage between the servo motor selection operation and the equipment's spatial location. The equipment location diagram indicates the motor's installation location or part within the equipment. By establishing a mapping relationship between motor objects and equipment location diagram information, the linkage between motor selection and spatial location display is achieved, thereby improving the operator's ability to identify the actual location of the motor and assisting in fault location and equipment debugging.

[0064] The technical solution provided by this invention integrates a unified selection and linkage interaction logic within a single human-machine interface. When a user selects a target servo motor, the system automatically matches and synchronously displays a schematic diagram of its device location based on the servo motor's identification information. This integrates three types of interactive functions—servo motor selection, status recognition, and spatial location visualization—into a single operation link, forming a unified interaction logic. This solution eliminates the fragmented design of existing technologies that require multiple switching between status monitoring interfaces, device drawing interfaces, and control operation interfaces. Servo positioning and location confirmation can be completed without navigating multiple pages, significantly shortening the operator's operation path, simplifying the interaction process, and achieving integrated collaboration between operation and visualization during servo debugging. This effectively improves the on-site debugging efficiency and operational convenience of multi-servo systems.

[0065] Optionally, the equipment location diagram is used to characterize the installation position and part of the servo motor in the tobacco packaging equipment, and is displayed in a designated area of ​​the interface.

[0066] Optionally, the unified identifier field can be either motor_code or ID, used for the association and matching of status parameters and control function parameters.

[0067] Optionally, the servo object collection supports dynamic expansion of more than 50 servo motors, adapting to large-scale multi-servo application scenarios in tobacco packaging equipment.

[0068] To address the challenges of numerous servos and complex control relationships in tobacco packaging equipment with multiple servo drivers, this invention introduces an XML-based configuration modeling mechanism. This mechanism provides a structured description of servo control objects, their state parameters, and control functions. By parsing configuration files, it automatically generates servo object models and corresponding human-machine interfaces, enabling dynamic construction and unified management of multi-servo systems. Furthermore, a multi-level servo control and state management mechanism is built. Through group mapping and templated interface generation, it achieves centralized monitoring and independent adjustment of the servo controller and servo motor operating states. Simultaneously, by combining batch data communication mechanisms and multi-source alarm information fusion methods, it collects and displays motor enable status, position feedback, current parameters, braking status, and fault information in real time. This improves system scalability and interface construction efficiency in scenarios with multiple servos (50 or more), reduces operational complexity, and enhances equipment debugging efficiency and operational stability, thereby ensuring the continuous, safe, and efficient operation of tobacco packaging equipment.
