1. Overview

Visualization applications recently used in manufacturing sites provide a way to express information such as the status of manufacturing equipment and process status in various panels (graphs, tables, numbers, etc.) as shown in Figures 1 and 2 so that information such as the status of manufacturing equipment and process status can be viewed at a glance. .

In order to construct a data visualization screen (dashboard), it is necessary to link various data generated in the factory and add and set panels that appropriately express the desired data. However, since this process is mainly carried out in the initial construction stage of a data visualization application, it is difficult for the field manager to respond if additional modifications to the screen are required due to changes in the field environment or indicators of interest after development is completed.

If the equipment manufacturer provides a digital information model containing the equipment information, along with interface setting information that can be connected to the equipment and pre-configured visualization screen configuration information for the equipment, the field manager can easily control the equipment A data visualization screen that can monitor the status of data will be built and can be easily placed or manipulated according to the method supported by the visualization system.

Inspired by this, in an embodiment of the present invention, a new data visualization information model required to visualize equipment data based on the asset management shell information model standard is defined, and a method of automatically generating a visualization screen for the equipment is provided with reference to this. present.

2. Asset management shell-based data visualization system

Figure 3 is a diagram showing the configuration of an asset management shell-based data visualization system according to an embodiment of the present invention. As shown, the data visualization system according to an embodiment of the present invention includes an information model creation unit 110 and a visualization screen creation unit 120.

The information model generator 110 provides connection information that can be linked to the data of the equipment in the data visualization system in the asset management shell where unique information (model name, manufacturer, specifications, etc.) of the manufacturing equipment is stored and for constructing a visualization screen of the equipment. Add meta information.

The visualization screen creation unit 120 extracts the corresponding information from the asset management shell to which connection information and meta information have been added by the information model creation unit 110, sets a data source for configuring a visualization screen (dashboard), and , automatically creates a visualization screen for the asset.

Detailed functions of the information model creation unit 110 and the visualization screen creation unit 120 will be described in more detail below.

3. Information model creation unit

Asset Management Shell is a standard that defines a modeling method to digitize the unique information of the manufacturing equipment that makes up a smart factory and all data generated from the equipment.

The international standard IEC 63278 specifies a submodel (SM) structure that can include the necessary properties according to the domain and classification of the data, and a submodel element (SubmodelElement) that expresses the data appropriately according to the nature of the properties. (hereinafter referred to as SME) is provided. A standardized SM composed of necessary attributes serves as a standard for linking or utilizing necessary data between systems. Figure 4 illustrates the submodel structure.

In the standard specifications, various types of SMEs are defined depending on the purpose and purpose of use. Among them, SMEs used in the embodiment of the present invention are as follows.

- SubmodelElementCollection (hereinafter SMC): SME that groups several SMEs to create a step structure

- Property: SME containing the name and value of the property

Based on this, in the embodiment of the present invention, DataVisualization SM is newly defined based on the asset management shell standard to provide the information necessary for configuring the data visualization screen of the equipment.

This can be viewed as the information model creation unit 110 adding a new sub-model containing information necessary for creating a data visualization screen for the equipment to the asset management shell for equipment at the manufacturing site.

DataVisualization SM consists of ① Datasources SMC, which is source information to retrieve data to be displayed on the screen, and ② Dashboard SMC, which is information on the type and arrangement of panels to display connected data.

① Datasource SMC is a group of submodel elements that contain connection information for connecting to the data server of the equipment needed to acquire data from manufacturing equipment.

Figure 5 shows the configuration of Datasource SMC. As shown, the Datasource SMC includes serverAddress, which contains the device's data server address and port number information.

In order to retrieve device data from a data visualization system, interface connection information is required to connect to the data server owned by the actual device, such as the OPC UA server of the actual device. Here, the connection information consists of the data server address and port number of the actual device.

② Dashboard SMC is a group of submodel elements that contain information about the visualization screen that will display equipment data. Figure 6 shows the configuration of Dashboard SMC. As shown, Dashboard SMC includes basicInfo SMC and panels SMC.

basicInfo SMC is information about the data visualization screen (dashboard), and panels SMC is information about individual panels. The data visualization screen consists of multiple panels, and the panels show data values received from actual equipment.

As shown in FIG. 6, basicInfo SMC is information about the title of the visualization screen, the layout style of the visualization screen, and whether the visualization screen is editable.

Additionally, the panels SMC is information about the panel name (text), panel type (type), panel title (title), panel position (position), and target node (targetNode).

The target node (targetNode) is information for acquiring the data of the target device that you want to visualize on the panel, and is a node ID that indicates the data to be read among various data held by the target device. On the visualization screen, data generated from actual equipment can be read based on the target node ID and changing data can be displayed.

In this way, based on the asset management shell standard, the asset management shell information model can be newly constructed by configuring the information of the server that will be linked with the actual equipment and the information of the panel that can visualize the data. Figure 7 illustrates the modeling results of DataVisualization SM.

4. Visualization screen creation unit

The visualization screen generator 120 uses the data visualization submodel of the asset management shell generated by the information model generator 110 to automatically generate a data visualization screen for the corresponding equipment.

As shown in FIG. 3, the visualization screen creation unit 120 includes ① an asset management shell model extraction unit 121, ② a data source registration and linking unit 122, and ③ a layout creation unit 123. The operation process of the visualization screen generator 120 is shown in FIG. 8.

4.1 Asset management shell model extraction unit

The asset management shell model extraction unit 121 extracts Datasources SMC and Dashboard SMC from DataVisualization SM. The method of extracting data from the asset management shell model file uses xPath, an XML Path Language, and finds the path of each node and extracts it.

In Datasources SMC, you can extract the address, port number, and authentication information of servers that can be linked with actual equipment, and in Dashboard SMC, you can extract information on each panel and the target node ID of the server to be displayed on the panel. The extracted data is delivered to the data source registration and linking unit 122 and the layout creation unit 122 using the internal API.

Steps S210 to S230 of Figure 8 correspond to the asset management shell model extraction process.

4.2 Data source registration and integration unit

The data source registration and linking unit 122 is a process of registering the data server of the equipment as a data source using the connection information extracted in step S220.

Data source registration is the section that processes the logic to link data with actual equipment. To link with a data server operated on actual equipment, you can connect to the server using a plug-in that supports the protocol. Therefore, you need to find the relevant plug-in, link it with the plug-in, and register the information of the server you will actually connect to in the data source.

More specifically, as a first step, the entire list of plug-in information within the data visualization system is retrieved and the presence or absence of plug-ins that can interoperate with OPC UA is checked through the filter function. If a plugin exists, it receives a unique ID value determined by the internal visualization system. If the plugin does not exist, the unique ID of the plugin is not sent in the API response, so the user proceeds to install the plugin.

In the second step, a list of data sources already registered within the data visualization system is retrieved. Compare the name of the data source you wish to newly register with the name of the previously registered data source, and if there is a duplicate name, add a number after the name to obtain a new data source name.

In the third step, if the redundancy check of the data source and plug-in is completed without errors, a new data source is created using two pieces of information: the unique ID of the plug-in you want to use and the name of the data source. The created data source has a unique ID to distinguish it.

In the fourth step, update the address, port number, and authentication information of the server you want to actually link to the data source information based on the unique ID.

As a final step, you can find a plug-in to link with the actual asset based on the server information previously extracted from the model extraction unit, and create a data source by linking the information of the server to be actually linked based on the plug-in.

Steps S240 to S270 of Figure 8 correspond to the asset management shell model extraction process.

4.3 Layout creation unit

In order to create a data visualization screen, the layout creation unit 123 configures a visualization screen based on the visualization screen information of the basicInfo SMC, and configures panels within the visualization screen from the panel information of the panels SMC to read in conjunction with actual equipment. Data is displayed to the user through each panel. This is done through the three steps below.

In the first step, a new model schema to be applied to the visualization system is created based on basicInfo SMC and panels SMC information extracted from Dashboard SMC. Here, the newly created model schema is a model structure that combines the information of the new data source created during the previous data source registration process and the existing panel information.

In the second step, when the newly created model is registered as a dashboard using the API, the data visualization system can finally refresh the screen (page) and output the completed screen.

In the third step, each panel inside the completed screen sends a query to the actual server in conjunction with the plug-in based on information from the previously registered data source, receives a response at each set cycle, and displays the data on the screen in real time.

Steps S280 and S290 in Figure 8 correspond to the asset management shell model extraction process.

5. Variation example
