[0002] Currently, many industrial control industries use drawing software to draw circuit diagrams, and some software based on database technology can achieve modular calls of circuits. However, due to different drawing levels and habits of each person, the expression modes are diverse; and the circuit designs of some electrical devices will be changed according to the operating environment or user requirements; making it impossible to achieve standardized unified management of the circuits in the software. Moreover, in circuit design, it is difficult to enumerate the types and combinations of components, and there are many circuit modules composed of various connection methods, making it difficult for designers to remember and correctly find the required circuit modules. Therefore, many circuit designers still choose to draw circuit diagrams stroke by stroke, which not only consumes engineering time but also easily leads to drawing errors, and does not give full play to the advantages of such drawing software.

[0033] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. In addition, it should be noted that for the convenience of description, only the parts related to the present invention rather than all the structures are shown in the drawings.

[0034] An embodiment of the present invention provides a circuit diagram management method, which can be executed by a circuit diagram management device. The device can be implemented by software and / or hardware, and is applicable to the management requirements of circuit diagrams containing a large number of components, with variable connection methods and frameworks, etc., and drawn by a large number of designers. It can achieve unified management of circuit diagrams in a modular and standardized manner. Figure 1 It is a schematic flowchart of a circuit diagram management method provided by an embodiment of the present invention. Refer to Figure 1 This circuit diagram management method includes the following steps:

[0035] S110. Extract at least one target area from at least one drawing in the drawing software, and classify the circuit diagram of the target area into a target placeholder as a variable in the target placeholder; wherein, the target placeholder is located in the placeholder list.

[0036] Among them, the drawing in the drawing software can be the original drawing stored in the drawing software, or a new drawing drawn by a designer according to the design requirements; the circuit diagram of the target area can include a single component, a partial wiring diagram of a component, or a complete wiring diagram of a certain device. There can be one or more target areas in one drawing; each target area corresponding to a target placeholder has one or several identical key features. That is to say, the target placeholder can be a general term for a type of variable. For example, when the target placeholder represents the control wiring of a motor, among all the variables it contains, the brand, certification standard, and installation position of the motor in the device are the same, and the difference lies in the rated capacity of the motor.

[0037] The process of classifying the circuit diagram of the target area into the target placeholder can specifically be: directly saving the circuit diagram of the target area as a variable to the target placeholder to form a function button corresponding to this part of the circuit diagram. Or, adjusting the circuit diagram of the target area according to the drawing rules of the target placeholder and then saving it to the target placeholder; wherein, the drawing rules of the target placeholder can include the font and size of the text part in the circuit diagram, the labeling rules of components, and the color and thickness of different wirings, etc.; in this way, the same standard can be set for the same type of circuits, which is beneficial to the unified management of circuit diagrams.

[0038] S120. Extract the name and features of the target placeholder; establish a database in the management software according to the names and features of all the placeholders in the placeholder list.

[0039] Among them, the names of the placeholders in the placeholder list are all different. The characteristics of the placeholder can include the characteristics of the placeholder itself and the characteristics of the variables therein. The characteristics of the placeholder itself can refer to the common characteristics of all variables in the placeholder, which are used to distinguish each placeholder; for example, the attributes (types), brands, certification standards, and voltage levels of the components in the placeholder, the positions of the variables in the device and in the drawing, etc. The characteristics of the variables can represent the unique characteristics of each variable in the placeholder, and the most prominent one of the unique characteristics of the variables can be taken to distinguish each variable in the placeholder. The number and type of the characteristics of each placeholder can be different.

[0040] Exemplarily, the database may include a data table composed of placeholder names and placeholder characteristics; the name and characteristics of each placeholder form a row of data in the data table. When a circuit diagram needs to be drawn, the designer only needs to query in the database according to the design requirement characteristics, and then can know the name of the placeholder corresponding to the requirement characteristics, so as to correctly call it in the drawing software. Therefore, the designer only needs to understand the design requirements, and does not need to memorize the correspondence between all placeholder names and placeholder characteristics additionally, nor does he need to struggle with how the naming of the placeholder is related to its characteristics when generating the placeholder.

[0041] In the circuit diagram management method provided by the embodiment of the present invention, a placeholder is made by using drawing software; and a management software is used to establish a database according to the name and characteristics of the placeholder, so that when the designer draws a circuit diagram, feature data can be formed according to the design requirements, and the database can be queried in the management software according to the feature data to obtain the name of the required placeholder, so as to correctly call the placeholder in the drawing software according to the placeholder name. In this way, it can not only avoid a large amount of repetitive work for the designer during drawing, but also avoid the problem of waste of placeholder resources caused by the difficulty of memorizing a large number of placeholder names. Moreover, through the placeholder, modular management of the circuit diagram can be realized, which is beneficial to the unification of drawing standards; the designer directly calls the placeholder for drawing, which can make the drawing styles drawn by different designers tend to be consistent, and the wiring methods and text expression methods tend to be unified. In addition, the placeholder is made and saved in the drawing software, and the database is established and saved in the management software, so that the two types of software complement each other and have complementary advantages, which can avoid the possible lack of functions and the impact on the running speed of the drawing software caused by only using the drawing software to establish the database and make calls. Therefore, compared with the prior art, the embodiment of the present invention can realize the unified management of the circuit diagram, thereby improving the drawing efficiency.

[0042] Figure 2 is a schematic flowchart of another circuit diagram management method provided by the embodiment of the present invention. Refer to Figure 2 , in one implementation manner, optionally, the circuit diagram management method includes:

[0043] S210. Extract at least one target area from at least one drawing in the drawing software and create at least one placeholder.

[0044] Among them, the placeholder is saved in a macro manner. Specifically, the placeholder can be formed when a target area of a certain drawing is selected and saved, and can be embodied in the drawing software in the form of a function button. When the placeholder is formed, storage spaces for multiple variables can be reserved and named with Arabic numerals or English letters. Subsequently, when similar areas are found in this drawing or other drawings, the variable spaces in the placeholder can be directly filled in the established order to update the placeholder.

[0045] S220. Test whether the placeholder can be successfully called; if so, execute S230; if not, return to execute S210.

[0046] Among them, this step is equivalent to a functional test of the placeholder, which can specifically include: testing whether the variables in the placeholder can be successfully called to form a new drawing, testing whether the variables of the placeholder after being called completely cover the required circuit diagram area, testing whether there are connection errors in the circuit diagrams of the variables in the placeholder, etc.

[0047] S230. Form a placeholder list.

[0048] S240. Extract at least one target area from at least one drawing in the drawing software, and classify the circuit diagram of the target area into the target placeholder as a variable in the target placeholder.

[0049] S250. Extract the name and characteristics of the target placeholder and record the name and characteristics of the target placeholder in the management software.

[0050] Among them, before the database is formed, the names and characteristics of each placeholder can be recorded first; this extraction and recording process can be manually recorded by the designer during drawing, or exported by the drawing software according to the original drawing. After the database is established, these records can be directly imported into the database.

[0051] S260. Establish a database in the management software according to the names and characteristics of all placeholders in the placeholder list.

[0052] This embodiment realizes the modular and standardized management of circuit diagrams through S210 - S260.

[0053] Based on the above embodiments, optionally, multiple feature positions can be reserved in the data table of the database for recording when new variables are added. The update process of the placeholder can be as follows: when the drawing in the drawing software is updated, the circuit diagram of the target area corresponding to the target placeholder in the updated drawing is classified into the target placeholder to update the target placeholder; this update process can be the modification or addition of variables. When the placeholder is updated, the corresponding part in the database is also updated accordingly.

[0054] Based on the above embodiments, optionally, the database also includes: at least one data file, and one data file corresponds to one placeholder in the placeholder list. The data file can be content such as a video, a picture, or a text introduction, and can be stored in the display position column of the placeholder in the data table of the database in the form of a hyperlink or a window.

[0055] Based on the above embodiments, optionally, the drawing software is EPLAN software. EPLAN software is a drawing software based on database technology. Its basic principle is to greatly reduce engineering time and costs through a highly flexible design method and by avoiding duplicate data entry. Whether it is for the creation and management of electrical projects, or for the archiving and sharing of drawing files, it has a very high level in the production of standard drawings and is very suitable for this circuit diagram management method. In the prior art, although EPLAN software is superior to traditional CAD software to a certain extent due to its own functions, due to different drawing styles of different designers and the difficulty of memorizing placeholder names, most designers still draw circuit diagrams stroke by stroke. In such a case, breakpoints or connection codes are easily changed incorrectly, and the advantages of this software are not fully utilized. Especially for filling equipment, in different customer demand usage scenarios, the enclosures of filling equipment are diverse, and the circuit design also changes accordingly, making it difficult to achieve unified management and not meeting the IEC standard. Moreover, when doing non-standard projects, many novel components will be encountered. If a certain component has been used before and the former designer knows its wiring, but those who newly come into contact with it often have to query a lot of information to determine it. In this way, resource sharing among the team cannot be achieved, and the work efficiency is low. However, by using the circuit diagram management method provided by the embodiments of the present invention, the statistics of placeholders can be realized, the placeholder name can be queried through features, and the drawing can be completed by calling the placeholder, and the management method is practical and feasible, giving full play to the advantages of EPLAN software.

[0056] Based on the above embodiments, optionally, the management software is EXCEL software, which can conveniently establish a database and manage data tables, facilitating the management of the database.

[0057] Next, taking the drawing software as EPLAN software, the management software as EXCEL software, and the drawing management of filling equipment as an example, combined with Figure 3 , the circuit diagram management method will be specifically described, but it is not a limitation to the present invention.

[0058] Figure 3 is a schematic flowchart of another circuit diagram management method provided by an embodiment of the present invention. Refer to Figure 3 , in one implementation, optionally, the management method of the circuit diagram includes:

[0059] S310. Create placeholders in the EPLAN software.

[0060] Specifically, this step can be: on a completed drawing, create placeholders according to requirements. The placeholders can include partial wiring diagrams of individual components, or wiring diagrams of the entire control motor. According to the filling process requirements, set the variables of the placeholders, give the placeholders specific names, and save them in the form of macros. The control buttons inserted into the development tools can be made according to specific needs.

[0061] S320. Test whether the functions of the placeholders meet the requirements; if so, execute S330; if not, return to execute S310.

[0062] S330. Update the drawing of the filling equipment and update the placeholder data.

[0063] S340. In the EXCEL software, count the names and characteristics corresponding to each placeholder, and classify and summarize various circuit diagrams of the filling equipment and their corresponding placeholders.

[0064] Among them, each placeholder can be classified according to the attributes of the components in the circuit diagram. For example, whether there is a motor and its power and voltage parameters; whether the voltage of the frequency converter controlling the motor is 220V or 380V; the location of the motor in the filling equipment; what other attributes are associated with the motor, etc. These provide data for the subsequent creation of a queryable database in EXCEL.

[0065] S350. Establish a queryable database in the EXCEL software.

[0066] Among them, the database can include data tables, and each row of the data table represents a placeholder.

[0067] S360. Import the names and characteristics corresponding to each placeholder into the database.

[0068] Exemplarily, the data table is shown in Table 1.

[0069] Table 1

[0070]

[0071] Referring to Table 1, by way of example, DDYYLLGG1 is the name of a placeholder for a breakpoint; DDYYLLGG2 is the name of a placeholder for a motor. Attributes, PLC brand, location of the device, drawing location, certification, and voltage are the common characteristics of the variables in the placeholder. The variables in the placeholder are named as variable A, variable B, and so on in sequence; the data columns corresponding to the variable parts in the table can be filled with the unique characteristics of the variable. For example, for the breakpoint, the variable characteristic is the breakpoint type; for the motor, the variable characteristic is the rated capacity.

[0072] S370. Import the data file corresponding to at least one placeholder into the database.

[0073] Among them, this step can be carried out synchronously with S360; or the database can be updated at any time after obtaining the data file. For the entire queryable database, a position for displaying the circuit diagram of new components can be reserved in advance, which is convenient for team resource sharing. Those newly coming into contact with it do not need to query a lot of information for wiring. Old employees also do not need to spend too much time explaining to new employees. The characteristics of the placeholders, circuit diagrams, and process diagram elements counted by EXCEL are imported into the database, and unified modular management can be realized.

[0074] This embodiment uses EPLAN and EXCEL software to realize modular and standardized management of drawings, achieving team resource sharing. This management method is flexible, automated, and convenient for parameter modification; it can effectively improve the drawing efficiency of designers and reduce the drawing error rate.

[0075] The embodiment of the present invention also provides a circuit diagram management device for executing the circuit diagram management method provided in any embodiment of the present invention, and has corresponding beneficial effects. Figure 4 It is a schematic structural diagram of a circuit diagram management device provided by an embodiment of the present invention. Referring to Figure 4 , this circuit diagram management device includes: a placeholder generation module 410 and a database establishment module 420.

[0076] Among them, the placeholder generation module 410 is used to extract at least one target area in at least one drawing in the drawing software, classify the circuit diagram of the target area into a target placeholder as a variable in the target placeholder; wherein, the target placeholder is located in the placeholder list. The database establishment module 420 is used to extract the name and characteristics of the target placeholder; and establish a database in the management software according to the names and characteristics of all placeholders in the placeholder list.

[0077] Based on the above embodiments, optionally, the placeholder generation module 410 is further configured to extract at least one target area from at least one drawing in the drawing software, create at least one placeholder, and form a placeholder list before classifying the circuit diagram of the target area into the target placeholder.

[0078] Based on the above embodiments, optionally, the circuit diagram management device further includes: a testing module, configured to test whether the placeholder can be successfully called after creating at least one placeholder.

[0079] Based on the above embodiments, optionally, the circuit diagram management device further includes: an updating module, configured to, when the drawing in the drawing software is updated, classify the circuit diagram of the target area corresponding to the target placeholder into the target placeholder and update the target placeholder.

[0080] An embodiment of the present invention further provides a circuit diagram drawing method, which can be executed by a circuit diagram drawing device and is implemented based on the database established in the circuit diagram management method provided in any embodiment of the present invention and the created placeholders, which can effectively improve the drawing efficiency and reduce the drawing error rate. Figure 5 It is a schematic flowchart of a circuit diagram drawing method provided by an embodiment of the present invention. Refer to Figure 5 , the circuit diagram drawing method includes:

[0081] S510. In the management software, query the name of the placeholder that meets the conditions in the database according to the drawing requirement feature data.

[0082] Among them, the database is established according to the circuit diagram management method provided in any embodiment of the present invention. The drawing requirement feature data is formed according to the circuit diagram design requirement.

[0083] S520. In the drawing software, call the placeholder according to the name of the placeholder and draw the circuit diagram.

[0084] Among them, the management software can be EXCEL software, and the drawing software can be EPLAN software. During the drawing process, if the circuit diagram of a certain module needs to be used, use the EXCEL database to screen according to various combined feature conditions and select the most suitable placeholder name of the circuit diagram. Insert the variables that meet the design requirements in the placeholder in the EPLAN software, and then make small changes according to the actual process changes to complete the circuit design of the module.

[0085] The circuit diagram drawing method provided by the embodiments of the present invention can effectively improve the drawing efficiency by searching for the placeholder name in the database of the management software based on the drawing requirement feature data, and then directly calling the placeholder in the drawing software. Moreover, it can make the styles of the circuit diagrams drawn by different designers or the same designer at different times consistent, and the wiring methods and text expression methods unified, which is beneficial to the standardization of the circuit diagrams. Additionally, directly calling the correct circuit module can effectively reduce the risk of connection errors when drawing the circuit diagram stroke by stroke.

[0086] Next, taking the drawing of the breakpoint as an example, the process of calling the placeholder will be specifically described, but it is not a limitation to the present invention. Exemplarily, the process of calling the breakpoint placeholder includes:

[0087] 1. Press the placeholder instruction button in the drawing software.

[0088] 2. Select the required placeholder name.

[0089] Among them, the name of the placeholder is obtained by searching in the database. As Figure 6 shown, for example, the placeholder name corresponding to the breakpoint is DDYYLLGG1. Clicking on this placeholder name can display a drop-down list as shown on the Figure 6 right side, and each row in the list represents a variable.

[0090] 3. Select the variables required in the placeholder to draw the circuit diagram.

[0091] As Figure 6 shown, here, I1.0 - I1.7 in the DI breakpoint are selected, and it can be seen that the DI breakpoint I1.0 - I1.7 and its numbers and other contents appear on the canvas. That is, the drawing of the DI breakpoint I1.0 - I1.7 is completed. The drop-down list of this placeholder may also include the DO breakpoint (not shown in the figure), which can be marked in the form of Q1.0 - Q1.7.

[0092] In summary, by calling the placeholder, the rapid drawing of the required circuit module can be achieved.

[0093] The embodiments of the present invention also provide a circuit diagram drawing device for executing the circuit diagram drawing method provided by any embodiment of the present invention, and it has corresponding beneficial effects. Figure 7 It is a schematic structural diagram of a circuit diagram drawing device provided by the embodiments of the present invention. Refer to Figure 7 , this circuit diagram drawing device includes: a name query module 710 and a circuit diagram drawing module 720.

[0094] Among them, the name query module 710 is used to query the names of placeholders that meet the conditions in the database according to the drawing requirement feature data in the management software; wherein, the database is established according to the circuit diagram management method provided by any embodiment of the present invention. The circuit diagram drawing module 720 is used to call the placeholder according to the name of the placeholder in the drawing software for circuit diagram drawing.
