Description

Technical Field

[0001] This application relates to the field of digital factory technology, and in particular to a modular digital factory construction method and system. Background Technology

[0002] Digital factories use data from the entire product lifecycle as a basis to simulate, evaluate, and optimize the entire production process through a computer virtual environment. In terms of early-stage factory design and process optimization, the application of digital factories can significantly shorten the construction cycle and reduce commissioning costs.

[0003] The current challenge is that digital factories require comprehensive data services as support. For example, during the factory design phase, warehouse and equipment models are needed, along with simulations of the production process. Digital factories deal with production scenarios involving numerous automated devices, sometimes requiring full automation. This involves a large number of equipment models, and remodeling all of them and constructing motion models presents a huge workload, especially when changes are made during the setup process, resulting in a significant amount of wasted work. Summary of the Invention

[0004] This application provides a modular digital factory construction method and system. By using motion analysis and combining it with appropriate instruction operation methods, the production flow can be obtained and the production process can be simulated. This method avoids model reconstruction and the construction of motion models, making it possible to quickly simulate the production process.

[0016] In one possible implementation of the first aspect, motion analysis of the virtual device includes:

[0017] The virtual device is broken down into its components;

[0018] The equipment parts are grouped according to their connection relationships to obtain part groups. The connection relationship between the equipment parts in the same part group is a fixed connection. The part groups form a connection grid. If there is a pair of parts in two part groups that have a connection relationship, the connection relationship is a non-fixed connection.

[0041] When a part is located inside the maximum cross-sectional shape, the grid lines associated with the maximum cross-sectional shape are retained.

[0042] In one possible implementation of the first aspect, simulating the production process using a production flow segment with a time parameter includes:

[0043] Virtual objects are continuously created in a time series and driven to move along production line segments. The movement of the virtual objects in each production line segment is based on the time parameters of the production line segment.

[0044] Adjust the interval between virtual object creations;

[0045] The inventory count is calculated based on the positional relationship between two adjacent virtual devices on the production line.

[0070] The technical solutions in this application will be further described in detail below with reference to the accompanying drawings.

[0071] This application discloses a modular method for building a digital factory. Please refer to [link / reference]. Figure 1 In some examples, this application discloses a modular digital factory construction method comprising the following steps:

[0072] S101, Obtain the virtual factory and place the virtual equipment into the virtual factory;

[0073] S102, Perform motion analysis on the virtual device and obtain the motion analysis results;

[0074] S103, Based on the motion analysis results, provide the connection relationship or connection suggestions for virtual devices;

[0075] S104, Associate virtual devices according to virtual device connection relationships and / or received instructions to obtain production flow lines;

[0076] S105, Use virtual equipment to cut the production line to obtain sequentially arranged production line segments;

[0077] S106, Assign time parameters to the production line segment according to the received instructions;

[0078] S107 uses production flow segments with time parameters to simulate the production process;

[0079] The production flow line includes the external flow line of the equipment and the internal flow line of the equipment;

[0080] In terms of sequence, external movement lines and internal movement lines are alternately set.

[0081] Specifically, in step S101, a virtual factory is first acquired and virtual equipment is placed into it. Both the virtual factory and the virtual equipment are generated based on a real factory and real equipment in the design or real-world environment. The virtual factory and virtual equipment are digital twins of the real factory and real equipment in the real-world environment. This is similar to building with blocks. After the virtual equipment is placed into the virtual factory, subsequent steps will analyze the placement result and provide the analysis results.

[0082] In step S102, motion analysis is performed on the virtual devices to obtain motion analysis results. The motion analysis results obtained here are mainly used to associate the virtual devices. Associating the virtual devices is to simulate the production process.

[0083] In step S103, the connection relationships or connection suggestions of the virtual devices are given based on the motion analysis results. Here, the connection relationships are explicit, while the connection suggestions are implicit and require intervention. In step S104, the virtual devices are associated according to the connection relationships and / or received instructions to obtain the production flow.

[0084] The instructions here are usually given by staff, meaning that staff need to intervene and handle situations where the connection to the virtual device cannot be obtained.

[0085] In step S105, a virtual device is used to cut the production line, resulting in sequentially arranged production line segments. Then, time parameters are assigned to the production line segments according to the received instructions, which is the content of step S106. Finally, in step S107, the production process is simulated using the production line segments with time parameters. The production line segments include external equipment segments and internal equipment segments, and in sequence, external equipment segments and internal equipment segments are alternately arranged.

[0086] To further describe the content described above, the method for building a complete digital factory should be to model it in virtual space and then simulate and analyze it. However, this method will take a lot of effort because the initial simulation may involve adjustments to the process. If equipment adjustments are also involved, then additional workload will be required, which will prolong the construction time.

[0087] The technical solution in this application can directly perform correlation analysis on virtual devices. The correlation analysis adopts two methods: automatic correlation and correlation based on received instructions. This mode can quickly build production lines and simulate the production process.

[0088] Taking a real-world scenario as an example, after placing virtual equipment into a virtual factory, the technical solution provided in this application can automatically generate and analyze production lines. In other words, after the process flow design is completed, relevant equipment can be placed in the virtual factory for simulation to obtain results without the need to rebuild the virtual equipment or construct motion models.

[0089] In some cases, motion analysis of virtual devices is performed in the following ways:

[0090] S201, disassemble the virtual device to obtain device parts;

[0091] S202, the equipment parts are grouped according to the connection relationship of the equipment parts to obtain part groups. The connection relationship of the equipment parts in the same part group is a fixed connection. The part groups form a connection grid. In two part groups with a connection relationship, there is a pair of parts with a non-fixed connection relationship.

[0092] S203, determine the association between the part group and the virtual device surface, and filter out the part groups that have a connection relationship with the virtual device surface based on the association relationship, and record them as the first part group;

[0093] S204, the motion analysis results of the first part group are obtained.

[0094] Steps S201 to S204 involve automatically analyzing and obtaining the actions of the virtual device. First, the device needs to be disassembled to obtain device parts. Then, the device parts are grouped according to their connection relationships to obtain part groups. It should be noted that a device part can only be assigned to one group.

[0095] When splitting, the splitting is based on the connection relationship. Here, only the bolt connection and the pin connection are split, because the part that performs the action in the virtual device needs to use the drive device, and the drive device is generally fixed by bolt connection. If transmission is involved, pin connection is often used.

[0096] During disassembly, first identify the bolt connections and pin connections, then disassemble all the bolt connections and pin connections. Next, group the equipment parts according to their connection relationships to obtain part groups.

[0097] If the equipment parts are still connected after being disassembled, then these equipment parts are considered as a group.

[0098] Part groups form a connection mesh. Among two part groups with a connection relationship, there is a pair of parts whose connection relationship is non-fixed connection.

[0099] Then, determine the association between the part group and the virtual device surface. Based on the association, filter out the part groups that are connected to the virtual device surface and denot them as the first part group. This step can obtain the part groups that are directly related to the virtual device surface. Specifically, when the part group is removed, the virtual device surface changes. The change refers to the loss of the virtual device surface when the part group is removed.

[0100] Finally, the motion analysis results for the first part group were obtained.

[0101] Specifically, part groups are divided into internal and external. Part groups marked as internal are not associated with adjacent virtual devices, while part groups marked as external are associated with adjacent virtual devices because this involves the movement of the processing object.

[0102] The motion analysis results for the first part group are obtained as follows:

[0103] S301, Determine the connection relationship of the first part group;

[0104] S302, Determine the range of motion of each part in the first part group;

[0105] S303, Sort the parts according to their connection relationship to obtain a sequence;

[0106] S304, restrict the range of motion of the next part in the sequence based on the range of motion of the previous part in the sequence.

[0107] The above method obtains the motion analysis result of the first part group through hierarchical restrictions, and at this time, the final motion analysis result is obtained. During the restriction process, the rule is to reduce the range of motion of the next part in the sequence. If the range of motion of the next part in the sequence cannot be reduced, then no restriction is required.

[0108] The action analysis results provide the connection relationships of virtual devices, as detailed below:

[0109] In one possible implementation of the first aspect, providing connection relationships or connection suggestions for virtual devices based on motion analysis results includes:

[0110] S401, the range of motion of the last part in the sequence is taken as the range of influence;

[0111] S402, Determine the connection relationship of the affected area. If there is a connection relationship, the affected areas overlap or the minimum distance is less than the allowable distance.

[0112] S403, associate with virtual devices within the scope of influence that have a related relationship;

[0113] S404, When the scope of influence cannot be determined by contact, a request is issued and a virtual device matching the request and connection suggestion is associated with the request.

[0114] This is determined based on whether the affected areas overlap or the minimum distance is less than the allowed distance, which is a set value. When the affected areas cannot be determined, a request is issued, and virtual devices matching the request and connection suggestions are associated with it; that is, the determination is made with manual assistance.

[0115] In some cases, the internal movement lines of the equipment are obtained in the following ways:

[0116] S501, analyze the virtual device to obtain the internal space of the virtual device;

[0117] S502, perform an analysis on the surface of the virtual device to obtain the interface that connects to the internal space of the virtual device;

[0118] S503 performs secondary analysis on the surface of the virtual device to obtain movable parts;

[0119] S504, create a virtual interface at a movable part and determine whether the virtual interface is connected to the internal space of the virtual device, and retain the interface that can be connected to the internal space of the virtual device.

[0120] S505, uses an interface that connects to the internal space of a virtual device and an interface that can connect to the internal space of a virtual device to create an internal mesh;

[0121] S506 generates internal movement segments of the device based on the internal grid or received instructions.

[0122] The above method first obtains the internal space of the virtual device, then performs a secondary analysis on the surface of the virtual device to obtain movable parts, then creates virtual interfaces at the movable parts and determines whether the virtual interfaces are connected to the internal space of the virtual device, and retains the interfaces that can be connected to the internal space of the virtual device.

[0123] The method for creating a virtual interface is to directly delete movable parts, and then determine whether the created virtual interface is connected to the internal space of the virtual device. If the parts that appear after deleting movable parts are still movable, then continue deleting until the created virtual interface is connected to the internal space of the virtual device or no more movable parts appear.

[0124] Please see Figure 2 and Figure 3 The resulting internal mesh may be simple or complex. A simple internal mesh can generate internal movement segments of the device. For example, the internal mesh may contain only one line segment or only a few line segments. Internal movement segments of the device can be generated according to the received instructions.

[0125] However, when the internal mesh is complex, it needs to be simplified. The simplification process is as follows:

[0126] S601, obtains the maximum cross-sectional shape of each grid line in the internal grid;

[0127] S602, compare the part with the maximum cross-sectional shape. The comparison method is to place the part on the maximum cross-sectional shape and move it to determine whether the part is inside the maximum cross-sectional shape.

[0128] S603, when the part is located inside the maximum cross-sectional shape, retain the grid lines associated with the maximum cross-sectional shape.

[0129] The specific method involves comparing whether the part can pass through the maximum cross-sectional shape of each grid line, keeping the grid lines that can be passed through, and deleting the grid lines that cannot be passed through.

[0130] In some examples, the specific way to simulate the production process using production flow segments with time parameters is as follows:

[0131] S701, Virtual bodies are continuously created in a time sequence and driven to move along a production line segment. The movement of the virtual body in each production line segment is in accordance with the time parameters of the production line segment.

[0132] S702, Adjust the interval for creating virtual objects;

[0133] S703, counts the backlog of two adjacent virtual devices in the production line;

[0134] S704, plot a comparison curve based on the interval time and the amount of backlog.

[0135] This method can determine if backlog has occurred. For example, if the interval between virtual objects is initially set to 5 seconds, a comparison curve will be generated after running for a period of time. The comparison curve will also change as the interval changes. Figure 4 As shown.

[0136] pass Figure 4 You can see the backlog at each location and make targeted adjustments.

Based on the association relationship, the part group that has a connection relationship with the virtual device surface is selected and denoted as the first part group.
