Detailed Description
The following description and the drawings sufficiently illustrate specific embodiments of the invention to enable those skilled in the art to practice them.
It should be understood that the described embodiments are only some embodiments of the invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of systems and methods consistent with certain aspects of the invention, as detailed in the appended claims.
In the description of the present invention, it is to be understood that the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art. In addition, in the description of the present invention, "a plurality" means two or more unless otherwise specified. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.
So far, in planning scheme design, a scheme planner typically edits a planning scheme by using a stand-alone modeling software (such as SketChup drawing software), and such an offline editing mode often causes misalignment and overlapping between models in the planning scheme, such as shown in fig. 2. In addition, the planning mode cannot perform a multitask parallel online editing mode, and only can perform flow operation among different departments, so that the working efficiency is reduced. Therefore, the application provides a multi-user collaborative editing method and system based on three-dimensional WebGis, so as to solve the problems in the related technical problems. In the technical scheme provided by the application, because the collaborator controls each layer in the editing graph to be associated with the collaborated person, the collaborated person only needs to complete each editing layer, so that each layer in the planning graph is not affected when being edited, for example, as shown in fig. 3, a plurality of collaborated persons edit each layer together on line, so that the editing time is reduced, the working efficiency is improved, and the following adopts an exemplary embodiment for detailed description.
The multi-user collaborative editing method based on three-dimensional WebGis provided by the embodiment of the present application will be described in detail below with reference to fig. 1 to 5. The method can be realized by relying on a computer program and can run on a von Neumann system-based multi-person collaborative editing system based on three-dimensional WebGis. The computer program may be integrated into the application or may run as a separate tool-like application. The multi-user collaborative editing system based on the three-dimensional WebGis in the embodiment of the application is applied to the terminal.
Referring to fig. 1, a schematic flow chart of a multi-user collaborative editing method based on three-dimensional WebGis is provided for an embodiment of the present application. As shown in fig. 1, the method of the embodiment of the present application may include the following steps:
s101, loading a planning drawing in the three-dimensional WebGis by a server;
wherein the server may be a coordinator (i.e., administrator backend). WebGIS (network geographic information system) refers to GIS (geographic information system) working on a Web network, is extension and development of the traditional GIS on the network, has the characteristics of the traditional GIS, and can realize retrieval, query, drawing output, editing and the like of spatial data. The planning diagram is a planning design scheme which needs to be completed by cooperation of multiple department personnel at the same time.
In a possible implementation mode, a collaborator opens a user terminal, logs in a system through a collaborator account and a password, when logging in the system, the system firstly verifies the account password, after the account password is successfully verified, the system analyzes and renders a browser page after successfully obtaining a layout drawing in three-dimensional WebGis, and finally displays the layout drawing in the three-dimensional WebGis to the collaborator.
Further, when obtaining the planning map in the three-dimensional WebGis, the browser jumps to another url address through a preset url address, the browser checks the domain name and queries a dns (domain name system) server to obtain an IP address, the browser sends an HTTP request to the web server, when the server receives the request, the server analyzes an action contained in the request to obtain HTML (hypertext markup language) data corresponding to the planning map in the three-dimensional WebGis responded by the web server through a service logic code corresponding to the action, and finally returns the HTML data of the planning map in the three-dimensional WebGis responded to the browser.
When the browser obtains data returned by the server, the browser constructs a DOM Tree according to HTML of a front-end page, generates a CSSOM (CSS object model) according to a pre-designed CSS (cascading style sheet) page style, integrates the DOM (document object model) and the CSSOM into a render Tree, finally fills HTML data of a layout drawing in the returned three-dimensional WebGis into the page, renders and displays the HTML data according to the render Tree, and finishes loading the layout drawing in the three-dimensional WebGis.
S102, the server receives an editing instruction of the planning map, judges whether the planning map exists in a prestored collaborative recording table and generates a judgment result;
the editing instruction is a command that a user clicks a button in the system to enable the planning chart to be in an editing state. The collaborative recording table is a recording table for storing a planning diagram edited by multiple persons in a collaborative manner. The judgment result is a result generated after the system judges whether the current planning chart has the collaborative recording table or not when receiving the editing instruction, and the judgment result comprises two conditions that the current planning chart has the collaborative recording table and the current planning chart does not have the collaborative recording table.
In general, whether to switch the corresponding graph layer to an editable state is determined according to whether the collaborator accepts the information.
In a possible implementation manner, after the planning map in the three-dimensional WebGis is loaded, when the judgment result shows that the planning map does not exist in the collaborative recording table, the system starts collaborative editing first, then adds the planning map to the collaborative recording table, then receives selection instructions for a plurality of editing layers of the planning map and selects the plurality of editing layers of the planning map based on the selection instructions of the layers, then receives selection instructions for editing users corresponding to each of the plurality of editing layers and selects editing users corresponding to each of the plurality of editing layers based on the selection instructions of the users, and finally sends the editing information of each of the plurality of editing layers to the editing users.
In a possible implementation manner, after the planning map in the three-dimensional WebGis is loaded, when the planning map exists in the collaborative recording table, the system first receives a selection instruction for a plurality of editing layers of the planning map and selects the plurality of editing layers of the planning map based on the selection instruction of the layers, then receives a selection instruction for an editing user corresponding to each of the plurality of editing layers and selects an editing user corresponding to each of the plurality of editing layers based on the selection instruction of the user, and finally sends the editing information of each of the plurality of editing layers to the editing user.
S103, the server selects the layers of the collaborative editing based on the judgment result, and adds the collaborated person;
for example, as shown in fig. 4, first, the creator of the planning scheme starts to perform settings of the collaborative state and the collaborative layer. The creator selects a scenario to be coordinated and switches the scenario to the editing state. At this time, the system will query the collaborative record table to see if the current solution is in the collaborative state. If so, the creator can perform operations such as adding or removing on the layer of the collaborative editing in the collaborative setting panel; if not, the collaborative edit needs to be opened in the collaborative settings panel, and the solution is added to the collaborative record table. Then, the creator sets the layers of the collaborative editing and has the authority to arrange a certain layer setting to be edited by the collaborator. Finally, after the cooperation setup is completed, the cooperator receives a message notification to prompt the user that the cooperation scheme can be edited and ask whether the user accepts. If the scheme is accepted, the setting of the collaboration state and the collaboration layer of the system is completed, and then a creator and all collaborators of the scheme can view and edit the scheme in a collaboration scheme interface in the platform.
S104, the client receives the collaborative editing information of the layer in the planning map;
the client is one end of a coordinated party (namely, an editing user end), the coordinated editing information is information generated when an administrator end (namely, the coordinating party) binds an editing task of a certain layer in a planning graph to a certain editing user, and the information is sent to a terminal system of the editing user in a wireless or wired mode.
In a possible implementation mode, an editing user opens a terminal and enters an editing user login page of the system through a URL address, the editing user logs in through an account password, and after the system verifies that the account password is correct, the editing user enters a preset home page of the system through a URL link. After entering the home page, the planning chart editing information sent by the collaborating party can be automatically popped up. After seeing the editing information, the user can receive the layers editable by the current planning graph by clicking a selection receiving button.
S105, the client displays the corresponding collaborative editing layer based on the collaborative editing information of the layer;
the collaborative editing layer is an editable layer which is formed by dividing one layer in the planning map to the cooperated party by the cooperative party.
In a possible implementation mode, a user selects to accept an editable layer, and after the user terminal receives the layer which is selected by the user to accept the editable layer, the user terminal loads the editable layer and displays a current interface of the editable layer to the user terminal.
S106, the client switches the collaborative editing layer into a collaborative editing state;
in a possible implementation manner, after an editable layer is displayed on a user terminal page, a system firstly obtains information of the editable layer, then inquires each node attribute of the editable layer in a planning graph through the information of the editable layer, after obtaining each node attribute in the editable layer, each node attribute in the editable layer is converted into a node attribute in an editable state, and after the conversion is finished, a client switches a collaborative editing layer into a collaborative editing state.
S107, the client receives the collaborative editing instruction, and carries out collaborative editing on the collaborative editing layer according to the collaborative editing instruction to generate a layer after collaborative editing;
in a possible implementation manner, when a client switches a collaborative editing layer to a collaborative editing state, an editing user can add, delete, modify and check the layer of a planning map according to specific design requirements, when adding, deleting, modifying and checking the layer, the layer is modified by inputting different editing instructions, after the editing user inputs a plurality of different modifying instructions, the client receives the input editing instructions, then edits the edited layer according to the editing instructions, and generates the layer after the editing is finished.
S108, the client receives and stores the command of the layer after collaborative editing, and judges the collaborative state of the planning map to generate a judgment result;
and judging whether the planning graph is a result generated by the collaborative state or not after the system of the client receives the storage instruction according to the judgment result, wherein the result comprises the collaborative state closing and the collaborative state opening.
In a possible implementation manner, when the judgment result is that the collaborative state is closed, the layout after collaborative editing is prohibited from being saved.
In another possible implementation manner, when the judgment result is that the collaborative state is started, the client system first obtains all layer data of the planning map after collaborative editing, then checks the planning map based on all layer data and generates a checking result, then modifies the layer data of the planning map according to the checking result, generates a modified planning map, and finally stores the modified planning map.
Further, the client system firstly acquires non-editable layer data from all layer data, then covers the non-editable layer data on the current non-editable layer to generate a modified non-editable layer, then acquires entity data in the edited layer, then acquires entity data in the editable layer in the database, when the entity data in the edited layer is inconsistent with the entity data in the editable layer in the database, replaces the entity data in the editable layer in the database with the entity data in the edited layer, and finally determines the edited layer and the modified non-editable layer as modified planning drawings.
And S109, the client saves the planning graph after collaborative editing based on the judgment result.
For example, as shown in fig. 5, when a collaborate finishes editing and saving a project, the system determines the collaboration state of the current project in the collaboration record table. If the data is closed, any data cannot be stored; if the system is started, the system will pull all the layer data stored in the database for the last time in the scheme to the local, and then check layer by layer. First, the system checks layers that are not collaboratively edited, which are modified by other collaborators, and which are not editable by the user. The local data cached before the layer is old data, and the latest data in the database is automatically replaced. Meanwhile, such layers are updated to the latest data in the three-dimensional scene of the user. Secondly, the system checks the layers cooperatively edited by the user, when checking layer by layer, each layer checks all entities contained in the layers and compares the entities with all entities of the current layer in the database, and if the data are inconsistent, the data in the database can be replaced by the local data. And finally, after all the layers are checked, uniformly submitting data to a database for data updating.
In the embodiment of the application, a server of a multi-user collaborative editing system of three-dimensional WebGis loads a planning map in the three-dimensional WebGis and receives an editing instruction of the planning map, judges whether the planning map exists in a prestored collaborative recording table or not and generates a judgment result, and then selects a layer for collaborative editing based on the judgment result and adds a collaborated person. The collaborated person receives the collaborative editing information of the layers in the planning map and displays the corresponding collaborative editing layers based on the collaborative editing information of the layers, then switches the collaborative editing layers to be in a collaborative editing state, receives a collaborative editing instruction and carries out collaborative editing on the collaborative editing layers according to the collaborative editing instruction to generate layers after collaborative editing, receives an instruction for storing the layers after collaborative editing and judges the collaborative state of the planning map to generate a judgment result, and finally stores the planning map after collaborative editing based on the judgment result. Therefore, by adopting the embodiment of the application, the collaborator controls each layer in the editing graph to be associated with the collaborated person, and the collaborated person only needs to complete the respective editing layer, so that the layers in the planning graph can be edited without influencing each other, and the layers of the collaborated persons are edited together on line, thereby reducing the editing time and improving the working efficiency.
