Description

Technical Field

[0001] The present invention relates to the technical field of communication between upper and lower computers, and more specifically, to an interface variable reading and writing optimization method, device and medium. Background Art

[0002] With the continuous development of industrial automation technology, industrial computer platforms based on Windows operating systems have been widely used in various industrial control applications. Specifically, the software runs on an industrial computer platform equipped with Windows system, and the industrial computer is connected to the PLC through a network cable. The software interface has text, edit boxes, drop-down check boxes and other items. The interface can read and write variables in the PLC and variables stored in the hard disk.

[0003] However, the existing interface variable reading and writing methods have some significant shortcomings, which affect the maintainability and scalability of the software. The existing technology is highly coupled in software structure, and the interface, communication, and file reading and writing modules are closely connected. This coupling leads to a complex software structure and is difficult to maintain. When adding or modifying parameters, it is necessary to add or modify code in multiple modules. There are too many things to modify, which increases the workload of development and maintenance. Summary of the invention

[0004] In order to overcome the technical problems existing in the above prior art, the present invention provides an interface variable reading and writing optimization method, device and medium.

[0005] In order to solve the above technical problems, the technical solution of the present invention is as follows:

[0006] A method for optimizing reading and writing of interface variables comprises the following steps:

[0007] Create an interface variable management configuration file, the interface variable management configuration file is divided into three levels, the three levels are the interface layer, the control layer and the control attribute layer;

[0008] Read all contents in the interface variable management configuration file into a mapping set;

[0009] Create an object pointer to store the control properties of the current interface;

[0010] When opening an interface or switching windows, assign the corresponding address to the object pointer according to the interface name;

[0011] When refreshing the interface, all properties of all controls in the current interface are traversed in sequence;

[0012] Determine the control type, and perform a preset operation according to the control type, wherein the preset operation includes directly displaying when the control type is text, and marking the modified value when the control type is an edit box or a drop-down check box;

[0013] When the interface clicks OK, the mapping set is traversed and the values ​​marked as modified are sent to the programmable logic controller.

[0014] Furthermore, the content stored in the interface layer is a list of interface names, the content stored in the control layer is a list of controls under each interface, and the content stored in the control attribute layer is a list of attributes for each control.

[0015] Furthermore, the control properties include variable name, title, default value, maximum value, minimum value, data format and unit, and the data format includes integer and decimal.

[0016] Further, the interface variable management configuration file is read, and all contents in the interface variable management configuration file are read into the jValueMap mapping set;

[0017] Create a JsonValue object pointer, which is used to store all control properties of the current interface.

[0018] Furthermore, when the interface is opened or the window is switched, the address of the content stored in the jValueMap mapping set is assigned to the JsonValue object pointer according to the interface name.

[0019] Further, when the control type is an edit box, it is determined whether the value is within a preset threshold range, and whether the value has been modified;

[0020] Values ​​that are within the preset threshold range and have not been modified are displayed in black text on a white background;

[0021] Values ​​that are not within the preset threshold range or have been modified are displayed in red letters on a white background, and the modified values ​​are marked in the object pointer.

[0022] Furthermore, when the control type is a drop-down check box, the option content corresponding to the displayed value is displayed in black text on a white background if it has not been modified, and in red text on a white background if it has been modified, and the modified value is marked in the object pointer.

[0023] Furthermore, when the interface clicks Confirm, the mapping set is traversed, all values ​​marked as modified are sent to the PLC, and all values ​​marked as modified are saved in the interface variable management configuration file.

Obviously, the drawings described below are only some embodiments of the present invention.

[0030] Figure 2 It is a schematic diagram of the principle of an interface variable reading and writing optimization method provided in an embodiment of the present application. DETAILED DESCRIPTION

[0031] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0032] Embodiment 1:

[0033] like Figure 1 As shown, the present invention provides a technical solution:

[0034] A method for optimizing reading and writing of interface variables comprises the following steps:

[0035] Create an interface variable management configuration file, which is divided into three levels, namely the interface level, the control level and the control attribute level; the content of each level has a clear definition and structure to ensure the consistency and integrity of the data;

[0036] When entering the software, the interface variable management configuration file is read, and all contents in the interface variable management configuration file are read into the mapping set;

[0037] Create an object pointer to store the control properties of the current interface;

[0038] When opening an interface or switching windows, assign the corresponding address to the object pointer according to the interface name;

[0039] When refreshing the interface, all properties of all controls in the current interface are traversed in sequence;

[0040] Determine the control type, and perform a preset operation according to the control type, wherein the preset operation includes directly displaying when the control type is text, and marking the modified value when the control type is an edit box or a drop-down check box;

[0041] When the interface clicks OK, the mapping set is traversed and the values ​​marked as modified are sent to the programmable logic controller.

[0042] Furthermore, the interface variable management configuration file is created using the JSON configuration file format, which has good readability and extensibility, and is easy to modify and update during the development and maintenance process.

[0043] Furthermore, the interface variable management configuration file is divided into three layers, and the contents stored in the layers are:

[0044] [Screen 1, 2, 3...]

[0045] [Control 1, 2, 3...]

[0046] [Control properties 1, 2, 3... (variable name, title, default value, maximum and minimum values, data format (integer / decimal), unit, etc.)]

[0047] That is to say, the software design method based on the MFC framework associates controls such as text, edit boxes, drop-down check boxes, etc. on the interface with configuration files. The configuration files include variable names, titles, default values, maximum and minimum values, data formats (integer / decimal), units, etc.; this is to solve the problem that when the existing method adds controls, there are too many items to be associated and the code is complicated.

[0048] Embodiment 2:

[0049] Based on Example 1, the content stored in the interface layer is a list of interface names, the content stored in the control layer is a list of controls under each interface, and the content stored in the control attribute layer is a list of attributes for each control.

[0050] That is, the interface layer stores a list of all available interface names, with each name corresponding to an interface. The control layer stores a list of all controls on each interface, with each control having a unique identifier. The control property layer stores detailed property information for each control, including variable name, title, default value, maximum and minimum values, data format (integer / decimal), unit, etc. Through this hierarchical structure, the configuration file can clearly display the controls and their properties of each interface, making it easier for developers to design and debug interfaces.

[0051] Furthermore, when the software starts, the system automatically reads the interface variable management configuration file and loads its contents into the mapping set in memory; the key-value pair structure of the mapping set ensures fast retrieval and efficient management. For example, you can use the interface name as the key and the corresponding control list as the value, and then use the control identifier as the key and the corresponding control attribute list as the value. The process of reading the configuration file includes parsing the file content, verifying the data format and integrity, and filling the data into the mapping set. If any errors are found during the parsing process, the system will record the log and prompt the user to check and correct them.

[0052] Further, if Figure 2 As shown, read the interface variable management configuration file, and read all the contents in the interface variable management configuration file into the jValueMap mapping set;

[0053] Create a JsonValue object pointer: pValueCur, which is used to store all the control properties of the current interface. Object pointers are used to store the control properties of the current interface. This method not only saves memory, but also improves the efficiency of data access. The dynamic management characteristics of object pointers ensure that resources can be quickly released and reallocated when switching interfaces, avoiding memory leaks and unnecessary performance overhead.

[0054] Further reference Figure 2 , when opening an interface or switching windows, the address of the content stored in the jValueMap mapping set is assigned to the JsonValue object pointer: pValueCur according to the interface name. When the user opens a new interface or switches to another window, the system will search for the corresponding control property list from the mapping set according to the name of the current interface, and assign the address of the list to the object pointer. In this way, the object pointer always points to the control properties of the current interface, ensuring the accuracy and real-time nature of the interface data. In order to improve the user experience, some transition animations or prompt information can also be added in this step to inform the progress of the user interface switching.

[0055] Furthermore, when refreshing the interface, the system will traverse the properties of all controls in the current interface and perform different processing according to the control type; the traversal process can be performed in the order of controls to ensure that the properties of each control can be checked and updated; for each control, the system will check its type and perform preset operations. For example, for text controls, the corresponding value is directly displayed; for edit boxes or drop-down check boxes, check whether the value has been modified and mark it accordingly.

[0056] Continue to refer Figure 2 , the preset operations of the control type are as follows:

[0057] Text control: directly reads the value from the control property and displays it. If the value changes, the system automatically updates the display.

[0058] Edit box: First check whether the value is within the preset threshold range (i.e., whether it is within the specified maximum and minimum range), and then determine whether the value has been modified. If the value is within the range and has not been modified, it is displayed in black text on a white background; if the value is not within the range or has been modified, it is displayed in red text on a white background and marked in the object pointer pValueCur.

[0059] Drop-down checkbox: Displays the option content corresponding to the value. If the value has not been modified, it is displayed in black text on a white background; if the value has been modified, it is displayed in red text on a white background and marked in the object pointer pValueCur.

[0060] Through these preset operations, the system can automatically handle different types of controls, reduce the workload of developers, and improve the consistency of the interface and user experience.

[0061] Furthermore, when the interface clicks Confirm, the mapping set (the total object jValueMap) is traversed, all values ​​marked as modified are checked, and all values ​​marked as modified are sent to the PLC; the sending process includes data format conversion and communication protocol processing to ensure that the data can be correctly transmitted to the PLC. In addition, the system will also save all values ​​marked as modified to the interface variable management configuration file so that the latest data can be loaded at the next startup.

[0062] In this embodiment, by storing the controls and their attribute information in the configuration file, the associated items in the code are reduced, making the code more concise and easy to maintain. The hierarchical structure of the configuration file allows only the configuration file to be updated when adding or modifying controls, without modifying a large amount of code, thereby improving the flexibility and scalability of the interface. The system can automatically handle different types of controls and display colors of different states, thereby improving the user's operating experience and the intuitiveness of the interface. By marking the modified values ​​and sending these modified values ​​to the PLC when confirming, the consistency and accuracy of the data are ensured.
