Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments, and all other embodiments obtained by those skilled in the art without making any inventive effort based on the embodiments of the present invention are within the scope of protection of the present invention.
As described above, although version management software developed based on the conventional version management method can conveniently realize version management of the text program, but cannot realize good version control of the graphical program, the embodiment of the invention newly increases the version control of the graphical program in the industrial PLC on the basis of the conventional version management, can realize the version management of the text program in a visual manner and also is compatible with the version management of the graphical program, can realize program distinction among different versions of visual management of a user, and is convenient and rapid to distinguish modified contents of different version programs or view modified contents of other people. Thereby improving program development and modification efficiency.
Specific implementations of the above concepts are described below.
Referring to fig. 1, an embodiment of the present invention provides a method for visually managing a PLC program version, including:
step 100, a main version library and a sub version library with version management software are obtained;
102, initializing the main version library and the sub version library by using the version management software to obtain version information of the main version library and version information of the sub version library;
and 104, updating the main version library based on the version information of the version library to obtain a main version library with an update record.
In the embodiment of the invention, the graphic programming class library of the world mainstream manufacturer is expanded on the basis of the versions of the git, and after the configuration files of the corresponding graphic programming class library are read by the version-dividing library, the corresponding library is automatically called to analyze the files, and records of corresponding operations are generated in the main version library; when the main version library detects the update of the text file, the text files in the two version libraries are converted into displayable images, so that whether the synchronized text files in the main version library are tampered or not is visually checked, and a new version with an update operation record is generated in the main version library after the fact that the text files are not tampered is determined. By the method, programs of different versions can be checked in a visual mode, programs of different versions can be quickly switched, the difference between the currently selected version and the program of the previous version can be checked, and visual version control of the version of the PLC program is realized.
The manner in which the individual steps shown in fig. 1 are performed is described below.
First, for step 100, a master version library and a partition version library with version management software are obtained.
In the embodiment of the invention, a git distributed version control management system is often used for realizing the management and control of the program version of the industrial PLC, and the system is provided with a main version library positioned at a central node and a sub version library positioned at each local node and obtained by cloning the main version library; when the operation records are actively uploaded by the version library, the master version library generates a version number for each received record, so that the subsequent historical version tracing and code modification evolution process checking are facilitated.
Further, the existing graphic program often has xml configuration files and analysis library dll files corresponding to the configuration files one by one, and when the xml configuration files of the graphic program are detected, the corresponding analysis library dll is automatically called to analyze the xml files, so that visual display of the graphic program is realized.
Furthermore, the master version library and the sub version library with version management software can be obtained by acquiring the dll files of each parsing library and installing the dll files into the distributed version control management system.
Then, for step 102, the version management software is utilized to initialize the master version library and the sub version library to obtain the version information of the master version library and the version information of the sub version library.
In the embodiment of the invention, after the main version library and the sub version library are acquired, the version management software initializes the main version library and the sub version library, records the version information of the two version libraries by traversing each file of the version library, defines that the main version library and the sub version library are initial versions at the moment, and detects and records the operation of a user in the version information of the sub version library in real time so as to update the main version library according to the version information of the sub version library in the next step.
It should be noted that, because the integrated development environment of the PLC is developed based on the disk file mode, that is, one or more files are created and modified under the corresponding project directory each time a program block or a project is created and modified. Therefore, if the user needs to use the version management software, after the project is newly built by using the PLC to develop the IDE, the version management system needs to be initialized under the project catalog, and the version management system needs to record the state as the initial state of the project. Since development languages such as ladder diagram programming LD, sequential function diagram programming SFC, function block diagram programming FBD and the like developed by each PLC have slight differences, a user can designate a kind of development language at the time of initialization in order to accurately distinguish between versions.
And aiming at step 104, updating the main version library based on the version information of the version library to obtain the main version library with the updated record.
Since the version management of the industrial PLC includes operation management of the graphic program and operation management of the text file, the update of the graphic program and the update of the text file are also classified when the operation record in the versioning library is updated into the master version library.
In the embodiment of the invention, when the graphic program is updated, the method comprises the following operations: comparing the current version of the main version library with the updated version of the sub version library by using version management software to obtain file information of a new pattern program of the sub version library; the file information comprises an updating position, operation information and a graph shape of the graph program; restoring the file information by using version management software to obtain a visual graph with operation information; wherein, the operation information comprises new addition, editing and deletion; uploading the updated version of the partitioned version library and the visualized graph to a main version library to obtain the updated version with the visualized graph, and generating a version number with the updated version of the visualized graph.
Specifically, since the version management software has defined the initial versions of the two version libraries during the initialization process, when detecting that a new operation is performed on the version-divided library (for example, modifying a graphic program or adding a graphic program, etc.), the version-divided library and the master version library at that time are compared, if the operation record is found to be absent in the version of the master version library, the version management software automatically records the file information of the new graphic program, including the update position, operation information, graphic shape, etc., and then when the updated version of the version-divided library is uploaded to the master version library, the version management software generates a new version having the operation at that time, and then repeats the above operations until all the operations of the version-divided library are recorded by the master version library and the new version is generated.
As shown in fig. 4, the principle of the PLC graphic program version record provided by the embodiment of the present invention is that the following is a version change process caused by a specific program change:
a) The user initializes the program version at time 2023-07-2312:00:09 with a program version number of V1.
b) The user inserts ladder diagram A1 at time 2023-07-2312:01:09, and then manually submits the version program with the program version number updated to V2.
c) The user modifies ladder diagram A1 at time 2023-07-2312:03:42, binding variable Vari1 to the input of ladder diagram A1 and variable Vari2 to the output of ladder diagram A2. The user then manually submitted the version program, with the program version number updated to V3.
d) The user finds the variable association error of ladder A1 at time 2023-07-2312:05:12, modifies ladder A1, binds variable Vari3 to the input of ladder A1. The user then manually submitted the version program, with the program version number updated to V4.
e) The user inserts ladder diagram A2 at time 2023-07-2312:07:02, and then manually submits the version program with the program version number updated to V5.
f) The user inserts ladder diagram A3 at time 2023-07-2312:07:23, and then manually submits the version program with the program version number updated to V6.
Further, after the version management software obtains the file information of the new graphics program, the version management software calls the installed analysis file to analyze the file information, so as to obtain a visual graph capable of representing the operation information of the graphics program, wherein the information comprises new addition, editing and deletion. For example, a new graphic program is represented by a green box, an edited graphic program is represented by a purple box, and a deleted graphic program is represented by a red box.
In the embodiment of the invention, when the text file is updated, the method comprises the following operations: acquiring a first character string used for representing the updated text file of the version library and a second character string used for representing the updated text file of the main version library; respectively carrying out format conversion on the first character string and the second character string to obtain first image information and second image information; based on the first image information and the second image information, an update text file of the versioning library and an update text file of the master version library are detected.
It is worth noting that the text file is not detected by the corresponding parsing library like a graphic program, the file defaults to be a correct and safe file when the text file is uploaded, but if the text file is tampered in the process of uploading from the versioning library to the main versioning library, the main versioning library is difficult to detect, so that the text file recorded in the versioning library and the text file synchronized in the main versioning library are required to be compared and detected by using the version management software, so that the security of the newly added text file in the main versioning library and the consistency of the newly added text file with the versioning library are ensured.
Specifically, the first character string and the second character string each include: attribute information of text files such as text type, text size, creation time, modification time; the first image information and the second image information obtained through conversion comprise image shapes, image pixels, image resolution and image saturation; the image shape is used to characterize the text type, the image pixels are used to characterize the text size, the image resolution is used to characterize the creation time, and the image saturation is used to characterize the modification time.
Generally, since the text type is a necessary factor for identifying and opening the text file, the text type of the text file is represented by the most obvious image information, such as when the file type is txt or doc, the converted image shape is triangle, and when the text type is htm, the converted image shape is square, so that once the user finds that the image shapes displayed in the two version libraries are different, it can be known that the text file synchronized by the main version library is different from the text file of the sub version library, i.e. the type of the text file is tampered; further, the size of the text file is represented by the image pixels, for example, the smaller the size of the text file is, the smaller the pixel value of the corresponding converted image is; the creation time of the text file is represented by the image resolution, the modification time of the text file is represented by the image saturation, for example, the earlier the creation time and the modification time of the text file are, the lower the image resolution and the image saturation obtained by corresponding conversion are, and the numerical values of the image pixels, the image resolution and the image saturation are not particularly limited, so long as the change along with the text size and the time can be represented.
In the embodiment of the invention, after corresponding image information is obtained, the first image information and the second image information are respectively converted to obtain a first image and a second image; based on the first image and the second image, an update text file of the versioning library and an update text file of the master version library are detected.
It can be understood that, as described above, in order to make the user more intuitively see the difference between the text file of the main version library and the text file of the sub version library, the embodiment of the present invention converts the image information into the corresponding image and displays the image on the screen, thereby completing the detection work of the text files of the two version libraries.
In the embodiment of the invention, the detection of the update text file of the version library and the update text file of the main version library comprises the following steps: displaying the first image and the second image by using version management software, and judging whether the first image and the second image have differences or not; if not, retaining an update text file of the main version library and generating a version number corresponding to the update content; if yes, uploading the updated text file of the version library again by using the version management software, and further checking the first character string and the second character string.
In the embodiment, a user can intuitively feel whether a difference exists between two text files by comparing the first image with the second image, so as to assist the user in detecting the text files, when the difference does not exist between the first image and the second image after comparison, the updated text files in the main version library are considered to be not tampered, at the moment, version management software can keep the updated text files in the main version library at the time, and a version number corresponding to the operation is generated, so that the follow-up of a history version is facilitated; when the difference between the first image and the second image is found after comparison, the updated text file of the main version library is considered to be tampered, the updated text file is removed from the main version library, the updated text file is uploaded again from the sub-version library, and the operation is repeatedly detected until no difference exists between the text file of the main version library and the text file of the sub-version library.
In summary, the version management software is utilized to analyze the updated graphic program of the version library to generate a visual graphic with operation information, and the visual graphic is combined with the main version library, so that the main version library can directly observe the updated record of the historical version of the graphic program; the text file is processed and converted by the version manager to obtain the corresponding image, so that the security and the correctness of the text file can be effectively detected when the text file is updated by the main version library, the text file with the error recorded by the main version library is avoided, and after the updating operation is finished, if a user wants to check version change, the version management software is only needed to be clicked, and the software can automatically restore the recorded version information into a graph for displaying.
