Description

Technical Field

[0001] The present invention relates to the technical field of controller drive control systems, and in particular to a multi-mode universal servo drive control system. Background Art

[0002] In the current field of industrial automation control, although controller technology is constantly improving, the existing drive controllers and their control systems are still limited by different machine models and communication protocols, so that the existing controllers can only focus on a single or one or two specific control modes. Since the control mode is fixed, when facing different slotting machine models or production environment requirements, only the matching controller can be replaced, resulting in a wide variety of controllers and poor flexibility in use. In order to meet a variety of production environments, various controllers can only be equipped for standby, resulting in high production costs and low controller utilization.

[0003] At the same time, in order to ensure the stability and reliability of the controller, the controller will also be set to a dedicated control mode when manufacturing the controller, which further limits the flexibility and scalability of the controller control system, making it difficult for the existing control system to be compatible with the controller, reducing the applicability of the control system. For example, the invention patent "A controller and a control system" with the publication number CN115685766A, although the controller discloses the integration of the local control mode and the centralized control mode, it is not for the operation process control of the running model, but only the integration of different control methods for the operator. For the operator, there are only two types of operation, local operation and centralized control operation, which are different ways of use for the operator. It does not affect the process operation of the equipment itself, that is, the equipment itself still operates in the operation process specified by the equipment, and there is no choice of diversified production modes. Therefore, it still leads to poor flexibility in equipment operation and is difficult to meet the flexible and universal requirements of multiple control modes. Summary of the invention

[0004] The present invention aims to provide a multi-mode universal servo drive control system to solve the problems of low adaptation efficiency of the existing servo drive control system, which makes the controller have low versatility, reduces the overall production efficiency and increases the production cost.

[0005] In order to achieve the above object, the present invention adopts the following technical scheme:

[0006] The present invention is used to provide a multi-mode universal servo drive control system that can be adapted according to different machine models and select corresponding mode parameters to meet different production requirements, improve the compatibility of the controller, and improve the versatility and production efficiency of the control system. Specifically, it is a multi-mode universal servo drive control system, including a control module, which is used to process input signals, execute control algorithms, and send control commands to actuators;

[0007] The mode management module includes a built-in mode library, a mode selector and a parameter configurator; the built-in mode library has 9 control modes pre-stored for different production needs; each control mode includes basic control logic and parameter items; the mode selector is used to select the corresponding control mode according to the machine model; the parameter configurator is used to set the corresponding parameter items according to the selected control mode;

[0008] The communication interface module is used to support multiple communication protocols and communicate with actuators and sensors of different models.

[0009] The principles and advantages of this solution are:

[0010] In the prior art, the software architecture of traditional controllers is often relatively closed and rigid. This is because due to the limitations of external technologies such as communication protocols and chips, there are differences in communication protocols, data formats and interface standards between different models and control modes. In order to ensure the stability and accuracy of the control system, a more simplified and reliable single control mode is often used to adapt to a specific controller. Therefore, it is difficult to achieve multi-mode control in terms of compatibility and adaptability. However, due to the lack of unified modular design and standardized interfaces in many controller systems on the market, the integration between different control modes becomes complicated and costly. Each control mode also requires independent hardware modules or software components, which makes it difficult to achieve seamless connection or fast switching. At the same time, in the prior art, even if multiple control modes can be integrated, the system still needs to process complex data and instructions from different modes and models at the same time, which puts higher requirements on the real-time and processing performance of the controller. However, in the prior art, due to the limitations of technical fields such as chips, it is difficult to meet the real-time processing requirements of multi-mode concurrency while ensuring high-precision control, so it is difficult to achieve a control system that takes into account both multi-mode adaptation and efficiency.

[0011] This solution adopts a multi-mode control system. Through the built-in mode library, a variety of parameter templates are set accordingly. It can be adapted according to different models. The adaptation of different models can be achieved by selecting the corresponding mode parameters, thereby improving the adaptation rate. It can switch between different modes of the same model, improve versatility, avoid repeated replacement, improve production efficiency, and reduce production costs at the same time to overcome the technical difficulties of chip missing.

[0012] Furthermore, the built-in mode library contains 9 parameter templates that match the control mode, and the parameter templates include machine model parameters, function parameters, operation parameters, tool parameters, cardboard parameters, production parameters and other parameters.

[0013] Furthermore, the machine model parameters include double-blade type and single-blade type; the functional parameters include slotting, detection, and paper feeding; the operating parameters include fully automatic, semi-automatic, and manual; the tool parameters include tool diameter and rotation speed; the cardboard parameters include cardboard thickness, hardness, size, and material; the production parameters include feed rate, feed speed, cutting speed, slotting depth, and slotting width; other parameters include slotting spacing.

[0014] Furthermore, the mode selector matches and selects corresponding machine model parameters according to the connected slotting machine model, obtains corresponding control modes under the corresponding machine model parameters, and forms corresponding parameter templates according to the control modes for setting the control modes.

[0015] Furthermore, the communication interface module includes an access terminal and a communication terminal, wherein the access terminal is used to access the machine type device, and the communication terminal is used to connect the machine type device to the control system for communication.

[0016] Furthermore, the mode selector includes a model identification unit for identifying the connected slotted model and obtaining corresponding model parameters, matching the corresponding control mode according to the model parameters, and obtaining the currently available control mode.

[0017] Furthermore, the parameter configurator is used to automatically load corresponding parameter templates and parameter items according to the acquired control mode.

[0018] Furthermore, it also includes a monitoring module for real-time monitoring of system status and fault diagnosis for the selected control mode.

[0019] Furthermore, it also includes an expansion interface module for reserving interfaces to add new functions or support more models.

[0020] Furthermore, the monitoring module is also used to detect the currently selected control mode and output adjustment suggestions based on the detection results. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Figure 1 It is a structural diagram of embodiment 1 of the present invention. DETAILED DESCRIPTION

[0022] The following is further described in detail through specific implementation methods:

[0023] Embodiment 1

[0024] Basically as attached Figure 1As shown: The multi-mode universal servo drive control system is compatible with 9 control modes. The corresponding mode parameters can be set according to different machine models, so as to achieve high adaptability, improve control efficiency, meet different production needs, and improve production efficiency, instead of using different control systems separately according to different machine models, so as to improve versatility and control flexibility. This drive control system includes a control module for processing input signals, executing control algorithms, and sending control commands to actuators.

[0025] The communication interface module is used to support multiple communication protocols and communicate with actuators and sensors of different slotting machine models. In this embodiment, the communication interface module includes an access terminal and a communication terminal, wherein the access terminal is used to access the machine model device, and the communication terminal is used to connect the machine model device with the control system for communication, so as to directly control the machine model device.

[0026] The mode management module includes a built-in mode library, a mode selector, and a parameter configurator. In this embodiment, 9 control modes are pre-stored in the built-in mode library for different production needs. Each control mode includes basic control logic and parameter items. In this embodiment, the built-in mode library is provided with 9 parameter templates matching the control mode, and the parameter templates include machine model parameters, function parameters, operation parameters, tool parameters, paperboard parameters, production parameters, and other parameters.

[0027] In this embodiment, the machine model parameters include but are not limited to double blade type, single blade type and other parameters; the functional parameters include but are not limited to slotting, detection, paper feeding and other parameters; the operating parameters include but are not limited to fully automatic, semi-automatic, manual and other operating modes. The tool parameters include but are not limited to tool diameter, rotation speed, etc.; the cardboard parameters include but are not limited to cardboard thickness, hardness, size, material, etc.; the production parameters include but are not limited to set feed amount, feed speed, cutting speed, slotting depth, slotting width, etc.; other parameters include slotting spacing, etc. In each control mode, there are corresponding parameter items. By adjusting the parameter items, the available control modes can be switched and adjusted, and the operation is more convenient and efficient.

[0028] In this embodiment, the mode selector matches and selects corresponding model parameters according to the connected slotting machine model, obtains the corresponding control mode under the corresponding model parameters, and forms a corresponding parameter template according to the control mode for setting the control mode.

[0029] The mode selector is used to select a corresponding control mode according to the connected slotting machine model. In this embodiment, the mode selector includes a machine model identification unit, which is used to identify the connected slotting machine model and obtain the corresponding machine model parameters.

[0030] According to the machine model parameters, a list of available control modes is matched from a preset control mode library to obtain the currently available control mode. An applicable control mode is selected according to the current production requirements. If the current machine model is a double-blade slotting machine, the corresponding parameters of the double-blade machine model are identified. Under this machine model parameter, n control modes suitable for the double-blade slotting machine model will be formed, where 1≤n≤9. In this embodiment, if the automatic mode is set, the optimal control mode will be selected according to the pre-set priority or production conditions.

[0031] The parameter configurator is used to set the corresponding control parameters according to the selected control mode. It is used to automatically load the parameter template of the corresponding control mode according to the model recognition result. According to the loaded template, the parameter value in the template can be set or adjusted. The system generates the final control parameter set based on the value entered by the user and the parameter template.

[0032] In this embodiment, by setting a variety of control templates and correspondingly setting corresponding parameter templates, fast adaptation and operation settings of different control templates of different models are achieved, and production setting operations are quickly completed, thereby improving adaptation efficiency. In addition, under the same model, the available control modes can be quickly switched, making the equipment more efficient and more flexible to operate, and can be applied to a variety of production and processing needs without having to replace the controller separately, further enhancing the versatility and flexibility of the system, effectively reducing production costs, and improving production efficiency.

[0033] Embodiment 2

[0034] Different from the first embodiment, this embodiment further includes a monitoring module and an expansion interface module. The monitoring module is used to monitor the system status and fault diagnosis in real time for the selected control mode. In this embodiment, the monitoring module is used to capture and display the key operating parameters of the system in real time, such as current, voltage, temperature, etc., so as to quickly understand the operating status of the current device in this mode, and generate the operating data of the control mode under this model, so as to optimize and update the control mode as historical data.

[0035] In this embodiment, the monitoring module analyzes the acquired operation data according to the acquired operation data. When an abnormality occurs, the system displays the abnormal data and the fault status and immediately issues an alarm. At the same time, in the fault state, the possible fault cause and countermeasures are provided according to the abnormal data. If necessary, the corresponding switch can be controlled to close, thereby effectively avoiding the expansion of the fault and ensuring the continuity and stability of production.

[0036] In this embodiment, the extended interface module is used to reserve interfaces to add new functions or support more models. In this embodiment, the extended interface module provides various types of interfaces, such as USB, Ethernet, serial port, etc., to meet the needs of different devices and functions. The extended interface module adopts a modular design, making it easier and more flexible to add new functions or support new models. Users only need to select the appropriate module for connection and configuration according to actual needs, and can easily realize the upgrade and expansion of the system.

[0037] Embodiment 3

[0038] Different from the first embodiment, in this embodiment, the monitoring module is also used to detect the currently selected control mode and output adjustment suggestions based on the detection results. In this embodiment, the monitoring module obtains the operating data under the current mode, such as current, voltage, temperature, etc. Combined with the slotting yield and the cause of defective products, the current control mode is analyzed for matching, including machine status, processing efficiency, stability, energy consumption, number of defective products, causes of defective products, etc., to obtain the matching degree between the current model and the control mode to determine whether the best operating effect is achieved.

[0039] According to the reasons for defective products, the monitoring module extracts the corresponding parameter items, selects better parameter values ​​or corresponding control modes according to the parameter items, and forms adjustment suggestions for the selected better parameter values ​​or control modes, which are fed back to users, so that users can choose better control modes without being limited to the existing mode adjustment thinking, and achieve more efficient and stable production. Effectively improve the adaptability and processing accuracy of the control mode, making the control mode more flexible.

[0040] In this embodiment, the key parameter item data of the acquired defective reasons are extracted to form initial data. After the initial data is cleaned, it is standardized or normalized to obtain data samples. The data samples are used to build an optimization model of defective reasons and corresponding parameter values. According to the existing data samples, the parameter values ​​or control modes are optimized through the optimization model. In this embodiment, a neural network can be used to establish the optimization model. The input of the model is set as the preprocessed parameter item, and the output is the predicted better parameter value or control mode. The calculation method from the input layer to the hidden layer is: (l) =w (l) a (l-1) +b (l) ; In the formula, z (l) is the weighted input of the lth layer; w (l) is the weight matrix from layer l-1 to layer l; a (l-1) is the activation output of the l-1th layer; b (l) is the bias vector of the lth layer.

[0041] The calculation method from hidden layer to output layer is: a(l) =σ(z (l) ), where a (l) is the activation output of the lth layer; σ is the activation function. At the same time, the loss function is used to measure the gap between the model prediction results and the actual results to further optimize the model and reduce the error.

[0042] According to the constructed optimization model, a database containing multiple control modes and corresponding parameter values ​​is constructed. According to the extracted parameter items, the optimal control mode or parameter value matching with it is searched in the database to form the output result and output it as adjustment suggestions. The adjustment suggestions include parameter adjustment values, control mode switching suggestions, etc.

[0043] In this embodiment, the monitoring module is also used to monitor and provide feedback on the operation results after the user selects the recommended solution, so as to further optimize the model and database.

[0044] The above is only an embodiment of the present invention, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
