first, the whole process of drawing the visual industrial configuration method needs to be combed, as shown in fig. 2: and showing the realization idea of the method by configuring the flow.
Firstly, establishing virtual model components, creating various elements by using GraphObject, effectively binding configuration data under the model and the model, expanding at least one configuration data text box bound by the virtual model components by using a member adding method, and adding the configuration data text box in a given set as a member of the set, wherein each virtual model component is assigned with a unique component key value.
Node templates and pipeline templates are defined, and each node and pipeline describes the text, shape, color and other information and interaction behaviors of the node and pipeline through the template. And filling and determining the relationship of the node template and the pipeline template through the data model, and rendering the node template and the pipeline template in a browser in a visualization mode. Each template is actually a panel, a port for connecting a pipeline is arranged on a node of each template, various elements can be freely combined in the template, and various interactive behaviors can be added in the template, wherein the interactive behaviors comprise: dragging, copying, pasting, selecting, right mouse button events, cutting, text editing, deleting, canceling, viewing information, templates, data source binding, event handlers, palettes, automatic layout, adding canvas or node listening events, and the like.
Dragging a virtual model component from a component library to a configuration page according to the component type required by a user, wherein when the virtual model component is created, the virtual model component can be understood as a painting brush, the configuration page is understood as a painting canvas, when the size attribute is set as a real number, the size attribute of a node is set as the natural size of the virtual model component, the stretching condition is not considered, the position attribute is set as an initial position, the virtual model component and the canvas are connected by using a pipeline template to form a complete visual industrial configuration interactive graph, and then an interactive behavior is added to the node template; the pointed adding interactive behavior is to add a mouse event to the node and realize the binding relationship between the mouse event and the node and the attribute under the node.
Selecting a data source from a database according to an industrial scene to respectively bind each virtual model component, and acquiring related data by a virtual model component object in a mode of setting configuration data; if node data is added or deleted from all the virtual model component sets on the canvas, methods of adding or removing members and the like need to be called; if only a certain node template object is desired to be modified, the model data needs to be modified in combination with the set property method, and given the string of named properties and new values, the override can change/delete the values of the node data or some properties of the data and can automatically restore all bindings.

The following is an example of the coal water slurry gasification process principle, as shown in fig. 3: the process flow for drawing the industrial configuration diagram is explained in detail:
the coal water slurry gasification reaction is a very complicated physical and chemical reaction process, and after the coal water slurry and oxygen are sprayed into a gasification furnace, the coal water slurry undergoes the processes of coal slurry temperature rise, water evaporation, coal pyrolysis volatilization, carbon residue gasification, chemical reaction among gases and the like, and finally, the combined gas taking CO and H2 as main components is formed.
Step 1: establishing a water-coal-slurry gasification process component library, selecting process components under the water-coal-slurry gasification process type, scaling the process components in an equal ratio by taking component graphs as drawing units according to the distribution condition of field equipment in the industrial process, reasonably distributing the process components in a canvas area according to the gas flow direction sequence, connecting the process components by using a pipeline, and repeatedly engraving a field process flow chart.
Step 2: binding each virtual model component to a data source, and taking a JSON object as a data model, such as: the graph source of the gasification furnace binds the data of the gasification furnace in the database, three areas of a jet area, a pipe flow area and a reflux area are arranged, and the coal water slurry respectively completes complex physical and chemical processes in different areas. The washing tower is bound with the data of the washing tower in the database, the washing tower is used for providing a water bath and gas-liquid separation space, and the gas-liquid phase mass transfer function of the four tower plates is utilized to separate solid particles in the synthetic gas, so that the gas washing function is realized, the temperature of the synthetic gas can be reduced, and the water-gas ratio of the synthetic gas can meet the production requirement.
And step 3: data are continuously updated to the database by collecting equipment data through the gateway, then a thread is started to poll the data in the database by using a websocket protocol when connection is established, and a data source actively pushes information to a configuration page to realize message intercommunication. After the protocol connection is successful, filtering the received message in the websocket method, outputting the message to a configuration data text box for updating page information, and if certain configuration data exceeds a threshold value, performing color change on the configuration data text box for prompting data alarm. By observing the values of temperature, pressure, etc. on the equipment, the influence on the synthesis gas is judged, and for exothermic reactions, the temperature is generally reduced to be beneficial to the reaction, and conversely, for endothermic reactions, the temperature is increased to be beneficial to the reaction. The concentration of the reactants with high pressure is increased, the reaction rate is high, the production capacity of the gasification furnace is correspondingly improved, and the on-site gasification process principle is simulated according to the operation data.
And 4, step 4: the historical data trend chart of certain configuration data in the whole industrial configuration page, such as the gasification reaction temperature historical trend chart, is checked, and because the historical data trend chart is an important process operation parameter, if the reaction temperature is high, more heat can be provided for improving the gasification reaction effect and influencing the content of each component of the synthesis gas. On the contrary, if the reaction temperature is too high, the service life of the gasification furnace is shortened, and the effect of long-term stable operation cannot be achieved. Therefore, observing that the reaction temperature operates in a certain range in a fluctuating way is a crucial part of the coal water slurry gasification process.
In conclusion, the method provided by the invention carries out configuration simulation aiming at the industrial production line flow, and improves the flexibility and the universality of industrial configuration. The method mainly starts from the flexibility of a user-defined configuration model, and elaborates the complete process from the uploading of a configuration diagram source, the configuration of a configuration interaction diagram, the binding of a data source and the final putting into use by a user. Therefore, the flexibility and the interactivity are higher, the operation is simple, and the use and study cost is lower.
