After the display screen display end is created, a scene can be created in the display screen display end by using the components, that is, different scenes can be created by using one display screen display end, and the different scenes comprise different visual components.

Each display screen control terminal can comprise a unique identifier. The display screen control terminal can acquire the identification of the display screen display terminal in the following way: the entry port of the display screen control end can be arranged in the display screen display end, and enters the display screen control end through the display screen display end, and at the moment, the display screen control end can automatically acquire the identifier of the corresponding display screen display end; or the display screen control end stores the identifiers of the display screen display ends corresponding to all the current items (one item corresponds to one or more display screen display ends, and the display screen control end can acquire the identifiers of the display screen display ends corresponding to all the items), displays the items in a list or pull-down bar mode, selects the identifier of one of the display screen display ends needing to be controlled currently, further acquires each scene list corresponding to the display screen display end after acquiring the identifier of the display screen display end, and selects the scene to be controlled (specifically, the display screen control end can select the item needing to be controlled from the item list, and then selects the identifier of the display screen display end needing to be controlled in the item and the scene needing to be controlled currently corresponding to the display screen display end).

In addition, a scene can be set in the display screen control end, and the scene corresponds to the scene in the display screen display end one to one and is used for controlling the display screen display end.

Further, in the above embodiment, the first display command may also control a plurality of display screen displaying ends at the same time. For example, the first display command may include identifiers of a plurality of display screens to be controlled and display control information, so that the synchronization service apparatus may distribute the display control information to the display screens corresponding to the identifiers of the plurality of display screens. For another example, the synchronization service device may be a service for synchronizing the states of a plurality of display screens of the same scene, and thus, the synchronization service device may store the association relationship between the identifier of each display screen and the scene displayed by the display screen. When the synchronization service device receives a first display command containing an identifier of a display screen display end to be controlled and display control information, the synchronization service device can search the associated scene according to the identifier of the display screen display end to be controlled and obtain identifiers of other display screen display ends currently displaying the scene, so that the synchronization service device sends the display control information to the identifier of the display screen display end contained in the first display command and the searched identifiers of the other display screen display ends, and the state synchronization of the display screen display ends of the same scene is realized. The present application can implement more variations, which are not described herein.

In particular, the display information may comprise, for example, a scene identification of the display. Therefore, the display screen control terminal can acquire scene display configuration information from the database according to the scene identification so as to display the same scene as the display screen display terminal according to the scene display configuration information. In some variations, the display information may include, for example, a displayed scene identifier and related display parameters, so as to facilitate the display screen control end to implement the same scene display, which is not limited by the present invention.

Specifically, the present invention can implement the playback of the content displayed by the display screen displaying end at the display screen control end through the steps shown in fig. 4, so that the display screen displaying end and the display screen control end implement the synchronization of the display, and the user can conveniently perform the display control on the display screen displaying end based on the display screen control end.

The display control method provided by the invention is described by a specific implementation mode:

firstly, a display screen display end is created, and a unique identifier of the display screen display end is generated, so that the display screen display end is associated with a plurality of scenes.

The display screen control end and the display screen display end respectively establish connection to a display control device (a server of synchronous service) through a communication protocol such as websocket.

The display screen display end subscribes information to the synchronous service by monitoring events and takes the unique identifier of the display screen display end as a synchronous service channel.

And the display screen control terminal acquires all scenes associated with the display screen display terminal from the database. When a user selects one of the scenes, the display screen control terminal reads data for controlling the current scene from the database, and renders and displays the data to the display screen control terminal. And simultaneously sending a first display command to the synchronization service, wherein the first display command may include information such as an identifier of a display end of the display screen, a scene identifier, and a control type of the display screen, such as a scene type.

After receiving the first display command, the synchronous service matches the subscribed display screen display end according to the identification of the display screen display end, and sends the received first display command.

And the display screen display end reads the scene configuration information from the database according to the first display command obtained by subscription, and renders the scene configuration information to the display screen display end for display.

When a user operates a button on an interface of a control end of a display screen, the control end of the display screen sends a first display command to a synchronization service, wherein the first display command comprises information of identification of a display end of the display screen, scene identification, component identification in a scene, component event, component type of control type and the like

After receiving the first display command, the synchronous service matches the subscribed display screen display end again according to the identifier of the display screen display end, and sends the received first display command.

And after receiving the message, the display terminal of the display screen triggers the update display of the component according to the control type, the scene identifier, the component identifier in the scene and the component event so as to achieve the interaction effect.

The display screen control end can also control the functions of scene switching, scene parameters, scene zooming, scene display self-adaption and the like in the display screen display end through a command with the control type being a function type.

The above is merely a schematic illustration of a specific display control process of the invention, and the invention is not limited thereto.

In some embodiments of the present application, a manner of scene display of the configured components is also provided. For example, a scene presented by a display screen presentation end may include a plurality of configured components generated from a visual configuration of component configuration information selected from a base component library. Wherein at least some of the components are configured with component events that trigger display interactions between the components.

In particular, the above-described embodiments may be implemented via a flowchart as shown in fig. 5. Fig. 5 shows the following steps in total:

step S210: the visual components are packaged through standardization.

Step S220: data formats, interaction behaviors, and data styles of visualization components are defined.

Specifically, a plurality of visual components can be packaged and defined in a standardized manner by means of steps S210 and S220, thereby forming a base component library. Specifically, the normalization in step S210 may be a standardized format uniformly set for the user, and the present invention is not limited thereto. Further, a basic component library is created in advance, and the basic component library comprises component configuration information of at least one visual component, wherein the component configuration information comprises component styles, component data and component events (interactive behaviors). Further, the component style includes information such as color, font size, border, and the like.

Step S230: the visualization components are configured using an interactable visualization configuration tool.

Specifically, a user can select at least one piece of basic component configuration information from a basic component library according to business requirements, generate a basic component according to the selected basic component configuration information in an interactive visual configuration tool, and set a display form according to component style information. A plurality of components constitute a business scenario.

Specifically, each basic component configuration information may correspond to an icon, the icon is displayed on one side of the visual configuration tool, the user selects the corresponding icon and drags the icon into the scene range of the visual configuration tool, the scene generates the corresponding basic component according to the basic component configuration information corresponding to the dragged icon, and the basic component is displayed according to the dragging position.

Further, after the basic component is dragged to the scene range of the visual configuration tool and displayed, the position and the size of the basic component can be determined in the following two ways: (1) and changing by selecting a basic component in the scene for dragging. (2) And selecting the basic component, and changing the basic component according to the mode of changing the position parameter in the configuration interface corresponding to the basic component, which is not limited by the invention.

Further, the basic components are selected one by one to the scene range of the visual configuration tool, and the number and the layout of the selected basic components can be changed in real time according to requirements. If the original requirement is four components in layout and 5 components are required after the requirement is changed, a new target basic component can be added on the basis of the original interface and dragged to the visual configuration tool to generate and display the basic component.

Step S240: interactive visual scene definition data is generated.

Step S250: rendering is performed according to the visualization scene definition data.

Step S260: and displaying at a display screen display end.

Specifically, the configuration information of the basic component generated and displayed in the scene is the initial standard information, and the setting can be changed according to different service requirements, so that the finally displayed component meets the service display requirement. The configuration information of the change base component may include change component style information, change component data, change component events. Further, changing the component style information can be realized by selecting the corresponding basic component and changing the style parameters in the configuration page of the corresponding basic component.

Changing component data can be accomplished, for example, by: and acquiring target data corresponding to the service requirement, and mapping the target data into the component according to the mapping relation between the component data defined in the component and the target data to realize component data visualization. Further, obtaining the target data corresponding to the service requirement may include the following three ways: (1) collecting data from a third party, storing the collected data in a database, defining different query statements according to business requirement indexes, and querying data corresponding to business requirements from the database to obtain target data; (2) the method comprises the following steps of adopting a customized form, manufacturing the customized form according to business requirements, and collecting input data of a user in the customized form as target data; (3) and calling a data interface of a service demand party to acquire target data. In addition, data can be inquired from the database at regular time according to business requirements and pushed to the component.

The change component event can be implemented, for example, as follows: and sending command information and data to other components by configuring and selecting other single or multiple component information. Further, after the component triggers the event, the target component can be sent and executed through the event configuration information, such as the target component, and the related parameters are transmitted, so that the target component can change the display form of the target component according to the naming information.

In particular, component events are used to conduct component interactions. The component interaction comprises: interaction between components, i.e. control of one component by another component or components; and interaction is achieved by changing scene parameters.

Specifically, the interaction between the components may implement the following functions: the configuration items of each component comprise component events, each component can set a plurality of events, and each event can control one or more other components. Specifically, taking the component a as an example to control the component B, the component C, and the component D, the event 1 is set in the component event of the configuration item of the component a: click, event 2: moving in; when the click operation acting on the component A is detected, a control command 1 is triggered, and the control command 1 is used for changing the styles/data of the component B and the component C; the configuration triggers control instruction 2 when a move-in event is detected that acts on component a, control instruction 2 acting to alter the style/data of component D. Specifically, the style of the component is changed: if the change component style is hidden or displayed, the change component style can also be other styles and can be configured in advance according to requirements; changing the data of the component may include changing all or part of the current data of the component, specifically configuring the data according to the business requirement, for example, the component B displays the data of the current month, and the control instruction 1 requests to change the data of the component B to the data of the previous month.

Further, after the configuration of the component A is completed, if the clicking operation acting on the component A is monitored on the display interface, a control instruction 1 is triggered, and the control instruction 1 carries the change information; and the component A sends the control instruction 1 to the component B and the component C, and the component B and the component C respectively change the self component style or data according to the change information carried in the control instruction 1. In addition, it should be noted that the changed style or data component B or component C in the change information itself should have the function, otherwise the control instruction is an invalid instruction; if the change information requires the component B to hide, but the configuration item of the component B itself does not hide the pattern, the control instruction is invalid, and the component B does not change.

Based on the above component interaction, the invention can also realize scene synchronization of a plurality of display screen display ends. For example, the same scene of multi-screen synchronization is displayed in a plurality of display screen display ends, and when one of the screens is operated for interaction, the other display screen display ends synchronously change in the same way.

Further, each visual scene will subscribe to the synchronization service when the display screen display end is opened. When the event of component 1 on scene a of the display side operates component 2. Component 1 will send an operation command and associated data to the synchronization service. The synchronous service pushes the command indiscriminately to a display screen display end of each subscribed visual scene, and the visual scene follows the received command to operate the component 2 in the current scene. Thus, the effect of synchronous change of a plurality of scenes is achieved.

Therefore, after the standardized interface definition is used for packaging the data visualization technology into the components, the effect of realizing different data visualization technologies can be ensured to have consistent data interface and interactive behavior processing modes, and the standardized visualization rendering engine is used for ensuring that the data visualization application is established under the automatic process under the standardized processing flow, so that the investment of labor cost is reduced, the development cost and the development period are greatly reduced, and the multiplexing of component multiplexing and interactive processing is realized; standardized service processing configuration can be rapidly completed according to different service requirements, finally, a standard visualization rendering engine is used for generating interactive visualization application, when the requirements are changed, only the changed part needs to be reconfigured, the configuration scheme is regenerated and re-rendered, and then the requirement change can be rapidly influenced.
