Technical problems and technical advantages solved by the present invention

In the present invention, each terminal (including the active terminal and the slave terminal) can perform instant communication while viewing the picture. Let all parties working together in CAD can view CAD drawings conveniently and quickly at any time when communicating and discussing.

Users of multiple terminals (including the active terminal and the slave terminal) view a CAD drawing at the same time, and can share the changes in the CAD drawing in real time. For example, after user A opens a drawing in their own terminal (as the active terminal), users B and C can see the opened drawing in their respective terminals (as the slave terminal) at the same time. When user A performs operations such as zooming in, zooming out, and panning the viewport on the drawing, the CAD drawing on the interface of the respective terminal of user B and user C will also change following the operation of user A. This makes the communication of each terminal more targeted, clearer, clearer, and more efficient. In particular, compared with the technical solution that relies on a web browser for drawing sharing, the present invention adopts a local CAD drawing sharing module to receive operation data, displays operations synchronously according to the operation data, and has stronger processing and calculation capabilities.

In terms of CAD drawing sharing, each terminal of the present invention displays CAD drawings cached locally, which is a vectorized graphic display (instead of using dot matrix pictures and displaying CAD drawings through video). Therefore, in the present invention, the users of each terminal see the CAD vectorized graphics, which are displayed clearly and meet the requirements of engineering drawings.

In addition, the changes and operations on the CAD drawings (ie real-time operations, such as adding annotations, moving the laser pointer, operating the enlargement, reduction, and translation of the CAD drawing viewport) are passed through parameters to realize the synchronous display of the CAD drawing of the slave terminal. Operations on terminal CAD drawings. Therefore, in the present invention, neither screenshots and/or video data nor the entire CAD drawings are transmitted in real time through the network, but operating data. Therefore, the synchronization of CAD drawings in each terminal is fast and real-time during the real-time discussion. Strong sex. That is to say, only the operation data of the CAD drawing needs to be synchronized, and the CAD drawing itself is not required to be synchronized. Therefore, the amount of transmitted data is greatly reduced, thereby improving the data synchronization speed and real-time performance.

Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

It should be noted that all the directional indicators (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the difference between the components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the relative positional relationship between the two, the movement situation, etc., the directional indication will also change accordingly.

In addition, in the present invention, descriptions involving "first", "second", etc. are only used for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of indicated technical features (for example, In the present invention, the description of the terminal as the “first terminal” and “the second terminal” is only to distinguish between the different roles played by the terminals and the different permissions they hold. For example, in some embodiments, the first terminal and the The software system of the second terminal is the same, but the permissions are different in different roles). Therefore, the features defined with "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

The "operating system" in this application file refers to a system that enables multiple people to participate in real-time discussions and real-time sharing of CAD drawings. It is also called "CAD drawing sharing discussion system" or "sharing chat drawing system" or " Discussion system based on shared CAD drawings". Specifically, the system is composed of multiple parts. For example, the operating system includes: a first terminal and at least one second terminal, wherein the first terminal is the active terminal, and correspondingly, the second terminal is the slave terminal. ; Of course, the roles between the first terminal and any second terminal can be interchanged, that is, the first terminal can be changed from the active terminal to the slave terminal, and any second terminal can also be changed from the slave terminal to the active terminal. terminal. Of course, the operating system can also include an independent shared server for role management (such as role assignment, role switching, etc.) and corresponding permissions (such as sharing of CAD drawings locally) between the first terminal and the second terminal. Real-time operation authority, authority to initiate drawing switching request, authority to initiate role switching request, etc.) configuration. For example, in response to a role switching request initiated by any second terminal indicating that it becomes the active terminal (that is, the target terminal), the second terminal is switched to the active terminal, and the role of the first terminal that was originally the active terminal is switched to the first terminal. Two terminal. Of course, the shared server can also be the first terminal or the second terminal, as long as it has the function of a server. For another example, the operating system includes: a server, and at least two clients that perform data communication with the server (specifically, the client can be connected to the server via the Internet/Internet of Things), wherein any client The server can be used for real-time sharing and instant communication of CAD drawings with other clients, and the server can be any electronic device with server functions, such as a user's mobile terminal or computer.

"Real-time" in this application document means that there is no significant delay in time. The “real-time sharing” in this article refers to when the user A participating in the discussion performs corresponding operations on the currently shared CAD drawings through the corresponding terminal/client (such as adding or modifying annotations, or zooming in/out the drawings, etc.). A and the other users B, C, and D participating in the discussion almost simultaneously see the operation results of the user A on their respective terminals/clients, which is also called "real-time synchronization". Correspondingly, the corresponding operations (such as adding or modifying comments) performed by the user A on the shared drawing are also referred to as "real-time operations".

"Instant" in this application document refers to outputting the output result associated with the input value in a very short time. In this article, "instant messaging" means that multiple users participating in the discussion can obtain the information input by the multiple users through their respective user terminals/clients in a short time or immediately through their respective user terminals/clients. For example, when user A enters the corresponding communication information (such as text) in the instant messaging area on the display interface of the corresponding terminal/client, and clicks send, other users B, C, and D participating in the discussion will be on the terminal/client The communication information input by the user A is received in a short time/immediately. Of course, when the user B sends the input communication information through the corresponding terminal/client, the terminals/clients of the users A, C, and D will also receive the communication information input by the user B in a short time/immediately.

(X1, y1), (x2, y2), (x3, y3), (x4, y4), (x0, y0) in this application file all represent a virtual coordinate point, for example, the CAD drawing corresponds to the viewport The coordinates of the two corner points in the display area of the CAD drawing of the terminal, or the coordinates of the laser pointer in the display area of the CAD drawing.

In this application, "vector diagram" refers to the description of a graphic or graphic image area in terms of specific graphic types (such as points, lines, circles, cones, etc.) and drawing parameters (such as coordinates, line widths, color values, etc.) Graphic data form of geometric characteristics, or composite vector graphics composed of multiple single vector graphics.

In this application, "role" refers to the role played by a terminal in the system of the present invention, for example, an active terminal, a slave terminal, and a free terminal; or, an active terminal, a slave terminal, and an autonomous terminal. The assignment of roles and the real-time operation authority of each role on the shared CAD drawings can be managed by the server or shared server, of course, it can also be managed by the active terminal. For example, only the active terminal or the client corresponding to the active terminal can perform corresponding real-time operations on the local shared CAD drawings, such as adding, deleting or modifying comments, etc.; or, the autonomous terminal/the client corresponding to the autonomous terminal can perform the current display Local CAD drawings (this local CAD drawing can be the currently shared local shared CAD drawing, or another CAD drawing stored locally, or another CAD drawing re-downloaded) to perform corresponding real-time operations, but the Real-time operations will not be synchronized to the active terminal/active end corresponding client and the slave terminal/slave corresponding client. Correspondingly, the active terminal/active end corresponding client will also perform real-time operations on the currently shared local shared CAD drawings. It will not be synchronized to the autonomous terminal/the corresponding client of the autonomous terminal. Of course, the active terminal, slave terminal, and autonomous terminal can also initiate corresponding role switching requests or role switching operations.

In this application document, "laser pointer" refers to the icon that floats above the CAD drawing and can be moved in the CAD drawing system. It is mainly used to indicate the specific position and entity in the CAD drawing during the exchange of CAD drawings. It can also be called "pointer", "laser pointer", "pick up the cursor on the operating object" and so on. Of course, the "operating object picking up the cursor" may not adopt the form of a laser pointer, and may also adopt other methods, such as a virtual mouse.

Example 1 Sharing chat picture operating system

An operating system for sharing chat pictures of the present application includes an instant messaging module (an instant messaging communication method includes drawings, text, voice, pictures, and videos, etc.) and a CAD drawing sharing module.

A shared chat image operating system of the present application can run on a PC terminal platform and/or a mobile communication device terminal platform.

The present invention provides an operating system for simultaneous instant messaging and simultaneous sharing and discussion of CAD drawings by multiple people, which can realize one terminal operation (ie "active terminal" or "operating terminal" 100) and other connected terminals (ie "slave terminal"). Or "display terminal" 102) synchronously display the changes of the CAD drawings on the active terminal or the operating terminal 100 in real time.

In some embodiments, when sharing a chat picture with multiple people, the target file (for example, CAD drawing) that needs to be discussed is uploaded on the server 104 first, and the user terminal that enters the shared chat picture discussion meeting first will be defaulted to The active terminal 100 (that is, the first user terminal connected to the server 104 will be configured as the active terminal 100 by the server 104 by default). The active terminal 100 downloads the target file from the server 104, and the server 104 identifies and records the target file downloaded by the active terminal. One or more terminals that subsequently enter the discussion meeting are automatically identified as the slave terminal 102 (for example, after the first one is connected to the server 104, all user terminals connected to the server 104 are configured by the server 104 as slave terminals. Mobile terminal 102). When the slave terminal 102 enters the conference, the server 104 sends a file download request (for example, by means of message push) or provides a file download link to the slave terminal 102 to guide the slave terminal user 102 to download from the server 104 and the active terminal 100 downloads the same target file (the target file has been identified and recorded by the server 104).

Of course, in other embodiments, when sharing chat pictures with multiple people, the server 104 may not be used. Instead, multiple user terminals may communicate data through a local area network, Bluetooth, or radio frequency. One of the user terminals can actively apply. Or everyone recommends that one user terminal (such as the first terminal) will become the active terminal 100, and other user terminals (such as the second terminal) will automatically become the slave terminal 102. Of course, the active terminal 100 may also have the function of a server, or at the same time may act as a server.

Of course, in other embodiments, the target file to be discussed may come from the active terminal 100, and the active terminal 100 first uploads the target file to the sharing server 104 for download by each slave terminal participating in the conference discussion. It can also be that any user terminal, such as the active terminal 100, uploads to the server in real time during the discussion.

In other embodiments, the active terminal 100 may not be set in a manner of joining order, but instead select one terminal from a plurality of terminals participating in the discussion as the active terminal 100. For example, the server 104 randomly selects a user terminal (such as the first terminal) and configures it as the active terminal 100, or a user actively initiates a request to become the active terminal 100 through its corresponding user terminal (such as the second terminal). Then the server 104 configures the user terminal as the active terminal 100. In addition, in the present invention, the role of each terminal is not fixed, and the authority of the active terminal 100 can also be transferred to the slave terminal 102 (that is, the roles of the active terminal and the slave terminal are exchanged, such as one of the slave terminals). The terminal initiates a role switching request to the server 104 or the active terminal 100), and the slave terminal 102 can also choose not to be controlled by the active terminal 100 to become the autonomous terminal 105, that is, the third terminal.

After each terminal 100, 102 obtains the target file that needs to be discussed, each of the target files is stored locally in the terminal, and the CAD drawing sharing module of the terminal (such as the active CAD drawing sharing module of the active terminal and the slave CAD drawing sharing module of the slave terminal) is respectively stored in the terminal. Drawing module) to open it, each terminal will enter the page (or current display interface) shown in Figure 2, including the CAD drawing display area and the instant messaging area. The above two areas can be distributed up and down or left and right on the terminal display interface. It can also be distributed on the terminal display interface in the form of overlapping coverage (for example, the instant messaging area floats on the CAD drawing display area).

In particular, the terminal A (ie, the first terminal) in FIG. 2 is the active terminal 100, and the terminals B, C, and D (ie, the second terminal) are the slave terminals 102. Both the active terminal 100 and the slave terminal 102 can communicate with each other through the instant messaging area. The communication methods include drawings, text, voice, pictures and/or video, etc. (such as the active instant messaging module of the active terminal 100, that is, the first terminal’s The first instant communication module obtains the communication information entered by the user in the corresponding instant communication area and sends it to the server 104 via the Internet. The server 104 instantaneously synchronizes the communication information to the slave instant communication module of the slave terminal 102, and also That is, the second instant messaging module of the second terminal). The active terminal 100 operates on the opened CAD drawing in the CAD drawing display area 132a, the slave terminal 102 obtains the operating parameters on the active terminal 100 through the server 104, and the slave terminal performs operations adapted to its own device according to the operating parameters. In some embodiments, the instant messaging module of each terminal transmits information through the server (for example, the chat information sent by terminal A through the instant messaging module is first uploaded to the communication server and then sent to the instant messaging modules of terminals B, C, and D. ). In some embodiments, the above-mentioned operating parameters for CAD drawings are also transferred between the terminals through the server. Please note that the communication information and operating parameters can be the same server or different servers.

In other embodiments, a separate server 104 may not be required between the active terminal 100 and the slave terminal 102, that is, the active instant messaging module of the active terminal 100 directly sends the acquired communication information to the slave terminal. The slave instant messaging module of the mobile terminal 102 is sent via Bluetooth, radio frequency, infrared, local area network, etc.; or, any user terminal with server function serves as a server at the same time, thereby completing the instant synchronization of operating data. For example, the slave terminal 102 can also directly receive the operating parameters sent by the active terminal 100 through communication methods such as Bluetooth, radio frequency, or infrared, or serve as a server at the same time (it may be the active terminal or any slave terminal, depending on actual conditions). Need to be configured) operating parameters sent from the user terminal.

In some embodiments, the slave terminal 102 can synchronize annotations with the active terminal 100. Specifically, the active terminal 100 makes annotations and instructions (that is, adding annotation data) to a certain part of the CAD drawing in the CAD drawing display area. The content of the annotation data can include text, lead, hand-drawn line, voice, and pictures (136a, 138a).

These annotation data are stored separately from the source data of the CAD drawings. The server 104 receives the annotation data from the active terminal 100, and then transmits the annotation data to the slave terminal 102 in real time. The slave terminal 102 synchronizes the local CAD drawings of the slave terminal 102 based on the received annotation data (ie , Add annotation data 136b, 138b). Similarly, when the annotations of the active terminal 100 change (create, modify, delete, etc.), the slave terminal 102 will also receive the changed annotation data in real time (via the server), and synchronize the annotations according to the changed annotation data. change.

By implementing the simultaneous display of annotations, users of various terminals can not only clearly see which point and/or entity the CAD drawing is discussed at, but also can immediately see the substantial content of the annotations (for example, text, lead, etc.) Hand-drawn lines, voice and pictures), so as to more accurately understand the situation of the discussion and improve the efficiency of the discussion.

In addition, when the slave terminal realizes the synchronous display of annotations according to the above technical solution, whether it is adding annotation data, or creating new or modifying annotations, the slave terminal performs the local software and hardware environment based on the received operation data.化 Operation.

In some embodiments, the active terminal 100 and the slave terminal 102 can realize viewpoint synchronization. Specifically, when the active terminal 100 performs operations such as zooming in and out or panning the viewport of the CAD drawing, these operations are actually changes in the two corners of the viewport, that is, the viewport is operated. When the active terminal 100 enlarges, reduces, and translates the CAD drawing in the CAD drawing display area, the position of the initial corner point changes, and the new corner point coordinates are transmitted to the slave terminal 102 through the server 104, and the slave terminal 102 obtains the new coordinates , Adjust the viewport to the new coordinates by yourself to realize the viewport synchronization. For example, the initial two corner coordinates of the active terminal 100 are (x1, y1), (x2, y2), after the viewport operation, the corner coordinates change to (x3, y3), (x4, y4), and the server 104 After receiving the new coordinates, they are transmitted to other slave terminals 102. After the other slave terminals 102 obtain the new coordinates, they adjust the viewport to (x3, y3) and (x4, y4) by themselves. In this way, the viewport of the slave terminal 102 can be synchronized with the active terminal 100.

One of the reasons why the present invention can realize fast and smooth viewport synchronization is that each terminal of the present invention displays CAD vector paper source data cached locally in the terminal, instead of the pictures and videos transmitted in the video conference or screen sharing (for example, QQ screen sharing). Specifically, each terminal (including the active and slave terminals) calls the same CAD drawing on the server 104. In order to improve the running performance, the CAD drawing on the server is actually downloaded to the local cache, and each terminal opens the local cache. CAD drawings. Therefore, in the present invention, the local CAD drawing can be opened in each terminal according to the actual conditions (software and hardware configuration) of each terminal, and it can be displayed by receiving the change/operation data from the active terminal and displaying the change on the local CAD drawing. operating. That is to say, when the slave terminal realizes the viewport synchronization display according to the above technical solution, whether it is the translation of the viewport or the enlargement and reduction of the viewport, the slave terminal is in the local software and hardware environment according to the received operation data. Localization operations performed.

In some embodiments, the active terminal 100 and the slave terminal 102 implement laser pointer 140a synchronization. Specifically, the active terminal 100 activates the laser pointer 140a to indicate the position of the CAD drawing, and the system will display the laser pointer 140a at the default initial position (x0, y0) on the CAD drawing in the CAD drawing display area, and set (x0, y0) at the same time. The server 104 transmits to each slave terminal 102, and each slave terminal 102 will also display the laser pointer 140b at (x0, y0) in the CAD drawing display area. At this time, the active terminal 100 picks up the laser pointer 140a and drags it, and changes the position of the laser pointer 140a to (x1, y1). The new position laser pointer data (x1, y1) is transmitted to the slave terminal 102 through the server 104 in real time, from The mobile terminal 102 automatically moves the laser pen 140b from (x0, y0) to (x1, y1), thus keeping the laser pen 140 synchronized on the display interfaces of the active terminal 100 and the slave terminal 102. In addition, when the slave terminal realizes the synchronous display of the laser pen according to the above technical solution, whether it is the display of the laser pen or the movement of the laser pen, the slave terminal performs the operation in the local software and hardware environment according to the received operation data. Localized operations.

In some embodiments, by default, the active terminal 100 is the first to enter the discussion meeting, and the slave terminal 102 is the terminal that subsequently enters the discussion meeting. In some embodiments, the active terminal 100 selects a new active terminal from the list of members entering the shared chat picture through the "change moderator" function in the shared chat picture system of the present invention, that is, performs role switching. Of course, the slave terminal can also be used. Actively initiate a role switching request to apply to become an active terminal. When the authority of the active terminal is transferred, the CAD drawing will not change. After the transfer, the new active terminal can do the above operations (for example, annotate the CAD drawing; zoom in, zoom out, and translate the viewport of the CAD drawing; in the CAD drawing Operate the laser pointer to indicate the position), you can also use the "View other drawings in the group" function to replace the CAD drawings.

In some embodiments, the slave terminal 102 chooses to disconnect the CAD drawing sharing with the active terminal 100 (that is, from the "drawing sharing state" to the "autonomous drawing state"), the slave terminal 102 after disconnection (that is, the autonomous drawing state) The terminal 105) can still use the instant messaging area (134a, 134b) displayed by the instant messaging module 200 of the terminal to understand the discussion, but the CAD drawings displayed in the CAD drawing display area on the autonomous terminal 105 will no longer be controlled by the active terminal 100. Therefore, you can independently operate the CAD drawings on your own terminal, and even change the CAD drawings displayed on your own terminal. In other words, the slave terminal 102 after the drawing sharing module 204 is disconnected will no longer be controlled by the active terminal 100. In some application scenarios, such a function is important. Some collaborative users have obtained the information they want after participating in some discussions, and they need to independently annotate and/or modify the local CAD drawings on their own terminals as soon as possible – The invention allows the CAD user of the slave terminal to opt out of the discussion (that is, choose not to share the CAD drawing synchronously with the active terminal) without affecting other slave terminals. In addition, because in the present invention, at this time, the CAD drawings opened on the slave terminal 102 are actually locally cached CAD drawings, and the displayed CAD drawings are displayed according to the local conditions of the slave terminal 102. Therefore, when the slave terminal 102 When switching from the shared view state to the independent view state, the interface of the CAD drawing display area will not have a big jump, and continuous and smooth switching can be realized. In other words, the viewport of CAD drawings will not change due to mode switching, and the user experience will be better.

When the discussion of a CAD drawing is completed, the active terminal 100 can choose to switch the CAD drawing to continue the discussion, or choose to end the discussion meeting. The annotation data added to the CAD drawing during the discussion can either be saved in the source data of the CAD drawing, or stored separately from the source data of the CAD drawing (but remain associated, so that when the CAD drawing is viewed again, all The annotation of will be displayed on the CAD drawing), the source data of the CAD drawing can be stored in the server 104, or can be stored in the local location of each terminal for the next discussion or viewing.

In the shared chat picture system of the present invention, all operations performed by the active terminal 100 in the CAD drawing display area 132a will be converted by the server 104 into operation instructions (command)/operation data and sent to the slave terminal 102, so that the slave terminal 102 The content displayed in the CAD drawing display area 132b of the terminal 102 is synchronized with the active terminal 132a. Of course, the active terminal 100 can also be directly sent to other slave terminals 100 through communication methods such as Bluetooth, radio frequency, or local area network, or by any user terminal that also serves as a server (may be the active terminal 100, or any slave terminal 100). Mobile terminal 102) sent to other slave terminals 102. Because only operating instructions are transmitted between the active terminal 100 and the slave terminal 102, the amount of data that needs to be transmitted is effectively controlled, thereby reducing the burden on the network, and there will be no occurrence of the slave terminal 102 caused by the heavy network load. The CAD drawing in the CAD drawing display area 132b shows the situation such as prolongation and freezing during the discussion of the meeting.

Example 2 Operation method of sharing chat pictures

The present invention also provides an operation method for simultaneous instant messaging and simultaneous sharing and discussion of CAD drawings by multiple people, which can realize one terminal operation (ie "active terminal" or "operating terminal") and other connected terminals (ie "slave terminal"). ) The operation method of real-time synchronous display of the CAD drawing changes of the operating terminal, to solve the technical problems such as inconvenience of multi-person collaborative drawing of CAD drawings and the inability to synchronize discussions and explanations in real time. In some embodiments, the following steps may be included:

Step 1. Upload the CAD drawings to be discussed to the server 104, set the first user terminal to enter the shared chat picture system meeting as the active terminal 100, and then send a request to the active terminal 100 to guide the active terminal 100 to download from the server 104 The CAD drawing to be discussed, for example, a reminder message containing multiple CAD drawings to be discussed (for example, a list of drawings to be discussed) is sent to the active terminal 100, and then the active terminal selects one of them as the target file to download . In some embodiments, the CAD drawings to be discussed are stored locally in the active terminal 100 at the beginning. In this case, the user of the active terminal 100 uploads the CAD drawings to be discussed to the server 104 for subsequent steps. The slave terminal 102 downloads.

Step 2: The server 104 recognizes the CAD file downloaded from the active terminal 100, marks and records it. When other terminals enter the conference, they are defaulted as the slave terminal. The server sends a download request to the slave terminal, and the slave terminal downloads the same CAD drawing file as the active terminal (that is, the currently shared shared local CAD drawing).

Step 3: The active terminal 100 and the slave terminal 102 respectively open the source data of the CAD drawing file stored locally, that is, the CAD drawing sharing module 204 is started, and the CAD drawing display area (132a, 132b) is displayed on the terminal interface; at the same time, the terminal is started The instant messaging module 200 displays instant messaging areas (134a, 134b) on the terminal interface, so that each terminal can perform information exchange functions while browsing the drawings.

Step 4. The active terminal 100 performs operations on the CAD drawings in the CAD drawing display area (132a, 132b), such as adding comments, adjusting the viewport, moving the laser pointer, etc., and the slave terminal 102 obtains the operating parameters of the active terminal 100 through the server 104 , And then make corresponding changes according to the operating parameters and the configuration conditions of the local device, and perform synchronization operations on the locally cached CAD drawings of the slave terminal 102.

Further, in order to realize multi-person interaction more efficiently, the active terminal 100 and the slave terminal 102 in the system can be PC terminals or various types of mobile terminals (smartphones, tablet computers, notebook computers, car computers, etc.). ).

Further, during the discussion, the active terminal 100 and the slave terminal 102 are switched, and the active terminal 100 can select a new member from the list of members who have entered the current shared chat picture through the "change moderator" function in the shared chat picture system. Host. After the authority of the active terminal is transferred, the CAD drawings displayed by each terminal will not change (because it is stored locally), so there will be no problems such as display interface jumps and unsmooth switching on each terminal. After the handover is completed, the new active terminal can perform the above operations such as adding comments, adjusting the viewport, and moving the laser pointer to the CAD drawings in the CAD drawing display area 132a, and can also use the function of viewing other drawings in the group to replace the CAD drawings.

Furthermore, during the discussion, the CAD drawing sharing module 204 between some slave terminals 102 and the active terminal 100 is disconnected to become the autonomous terminal 105, but the autonomous terminal 105 can continue to use the instant messaging module 200. These disconnected slave terminals 102 will no longer follow the active terminal 100 to synchronize operations on the CAD drawings. Users who disconnect the slave terminal 102 can perform independent operations on their local CAD drawings, or even replace them with other CAD drawings. , But you can still see the ongoing discussions in the instant messaging area (134a, 134b). In some application scenarios, such a function is important. Some collaborative users have obtained the information they want after participating in some discussions, and they need to make their own annotations and/or modifications to the local CAD drawings on their own terminals as soon as possible – The invention allows CAD users of the slave terminal to choose to exit the discussion (that is, choose not to synchronize with the active terminal), and will not affect other slave terminals.

In some embodiments, the above-mentioned autonomous terminal 105 may also reconnect with the active terminal in subsequent operations and become the slave terminal 102 again, or obtain the control right from the active terminal 100, that is, become the new active terminal 100, and Upload the CAD drawing source data that you modify and store locally to the server, and then transfer it to each slave terminal to become a new subject of discussion.

Example 6

The present invention also provides a CAD drawing sharing server, which is respectively connected to the active terminal and one or more slave terminals through the Internet of Things/Internet of Things, and performs data communication to send and receive data to and from the active terminal and the slave terminal. Share CAD drawings, specifically, it includes:

The data synchronization module is used to receive the operation data generated when the currently shared local shared CAD drawing is operated correspondingly sent from the active CAD drawing sharing module of the active terminal 100, and synchronized to the slave CAD of each slave terminal 102 in real time Drawing sharing module, to synchronize the operation data by the slave CAD drawing sharing module;

The instant response module is used to instantly forward the communication information between the active terminal and the slave terminal; for example, the communication information sent by the active terminal is instantly forwarded to all slave terminals, or the communication information sent by the slave terminal is instantly forwarded To the active terminal and other slave terminals.

In some embodiments, the locally shared CAD drawing currently shared may be downloaded from the server and stored locally when the active terminal and the slave terminal are connected to the server; or it may be pre-stored locally by the active terminal. After that, it is directly sent to each slave terminal for local storage, that is, the CAD drawing displayed in the CAD drawing area in the current display interface of the active terminal and the slave terminal is actually a local copy of the same CAD drawing on different terminals Product.

In some embodiments, the CAD drawing sharing server may be implemented by a dedicated server or a user terminal with server function.

In some embodiments, the CAD drawing sharing server further includes a role/authority management module for pre-assigning roles to multiple user terminals with which it performs data communication, and configuring each role's operation authority for the shared CAD drawing . For example, the CAD drawing sharing server configures the first user terminal connected to the CAD drawing sharing server as an active terminal with real-time operation rights on the shared CAD drawing by default, and connects others to the CAD drawing sharing server. The user terminal of the server is configured as a slave terminal that has no operation authority on the shared CAD drawing.

Of course, in other embodiments, the CAD drawing sharing server can also randomly select one of multiple user terminals connected to the CAD drawing sharing server to be configured as the active terminal, or, in response to an initiative initiated by a user terminal, it can become the active terminal. The terminal's request configures it as an active terminal.

In some embodiments, the role/authority management module of the CAD drawing sharing server is further configured to send a role switching control instruction to the target client in the role switching request in response to a role switching request sent by the active terminal/slave terminal, and Perform role switching according to the role switching response message fed back by the target client. For example, the active terminal sends a role switching request to switch one of the slave terminals (or the terminal corresponding to the target client, usually specified by the user corresponding to the active terminal that initiates the role switching request) to the active terminal, and switches itself to the slave Terminal, the server sends the corresponding role switching control instruction to the corresponding slave terminal according to the role switching request, and correspondingly, the slave terminal feeds back the corresponding role switching response message (which includes acceptance/rejection of role switching) Control instructions) to the server to perform corresponding role switching operations. Of course, the role/rights management module is also used to initiate a disconnection in response to a disconnection request sent by the active terminal/slave terminal (or the active terminal corresponding to the client/slave terminal corresponding to the client) indicating disconnection of the sharing discussion The requested user terminal is configured as an autonomous terminal.

In some embodiments, the CAD drawing sharing server further includes a drawing switching module for responding to the drawing switching request sent by the active terminal or the slave terminal, according to the target CAD drawing in the drawing switching request (usually the target CAD drawing is created by The marking information corresponding to the user specified by the user terminal that initiated the drawing switching request performs drawing switching on the active terminal and the slave terminal connected to the server.

Embodiment 7 CAD drawing sharing instant discussion system

The present invention also provides another CAD drawing sharing instant discussion system, which includes a server and at least two clients that can communicate with the server. Among them, the server can perform role management on at least two clients connected to the server, and configure real-time operation permissions for each role on the shared CAD drawings; and the client configured as the active side can control the currently shared The CAD drawings are shared locally for real-time operation, and the corresponding operating data is instantly synchronized to the corresponding client of each slave through the server, so that each client can perform corresponding synchronization processing according to the operating data.

In some embodiments, the server includes:

The role/authority management module is used to perform role management on at least one client connected to the server, and/or each role performs real-time operation of the currently shared local shared CAD drawings; specifically, the role/ The authority management module is used to configure the first client connected to the server as the active terminal with real-time operation authority for the local shared CAD drawings, and accordingly, configure other clients connected to the server to Slave end without real-time operation authority for local sharing of CAD drawings;

The data synchronization module is used to receive the operating data sent by the client configured as the active end (ie, the first client), and synchronize it in real time to each client connected to the server and configured as the slave ( That is, the second client), so that each client on the slave side synchronizes their currently shared local shared CAD drawings according to the operating data; the instant response module is used to receive the communication sent by the client configured as the master And send the communication message to each client connected to the server and configured as a slave, so that each client of the slave synchronously displays the communication message in their respective current display interfaces.

Wherein, the operation data is the same as the operation data in each of the foregoing embodiments, and will not be repeated here; for the same reason, the communication message is the same as the communication message in each of the foregoing embodiments, and will not be repeated here.

In some embodiments, the client includes:

The shared CAD drawing module is used to respond to the real-time operation of the corresponding user on the currently shared local shared CAD drawing, obtain the corresponding operation data, and send the operation data to the server in real time; or, receive the real-time synchronization of the server Incoming operating data sent by other clients, and synchronize the local shared CAD drawings according to the received operating data; specifically, if the client is configured as the active end, the corresponding user has the authority Perform corresponding real-time operations on the local shared CAD drawing, then the shared CAD drawing module obtains the corresponding operating data and sends it to the server in real time to synchronize to the shared CAD drawing modules of each slave for synchronization operation; if the client If it is configured as a slave, the corresponding user does not have the authority to perform corresponding real-time operations on the local shared CAD drawing. Accordingly, the shared CAD drawing module cannot obtain the corresponding operating data, but receives the data from the server. Synchronize the operating data of the active end and perform corresponding synchronization processing;

The instant communication module is used to respond to the corresponding user's communication operation in the current display interface, obtain the communication information input by the user, and send it to the server; or, receive the instant communication information sent by the server, and perform synchronous display .

Wherein, the synchronization process is the same as the synchronization process in the foregoing embodiments, except that it only synchronizes drawing modification data, such as added or modified notes, or data such as the enlargement or reduction of the drawing, rather than the modified CAD drawing itself.

Further, the master and slave can be switched. For example, any client (which can be the client corresponding to the master or the client corresponding to the slave) can actively initiate a role switching request (such as The user clicks on the role switching icon in the current display interface of the corresponding client), and the server controls the role switching.

In some embodiments, the client further includes:

The first request module is used to generate and send a role switching request to the server in response to the role switching operation initiated by the corresponding user; specifically, the role switching request includes the unique identification information of the target client specified by the user; The user corresponding to the slave initiates a role switching request to replace the new active end, then the target client is the corresponding client of the new active end specified by the user; if the user corresponding to the slave initiates a role switching request to become the new active end , The target client refers to the client corresponding to the slave that initiates the role switching request.

Correspondingly, the role/authority management module of the server is also used to respond to the role switching request, send a role switching control instruction to the target client, and perform role switching according to the role switching response message fed back by the target client; wherein, the role The switching response message includes: a control instruction indicating acceptance/rejection of role switching.

Specifically, the user corresponding to the target client can choose to accept the role switch to become the new master/slave, or can choose to refuse the role switch to maintain the current role, and feedback the corresponding response to the server through the target client The role switching response message is sufficient. Of course, when the client that initiated the role switching request receives a role switching response message indicating rejection, it is understandable that it can initiate a new role switching request again.

Furthermore, in the course of the discussion, the drawing can be changed to discuss the new drawing. For example, any client (it can be the client corresponding to the active end or the client corresponding to the slave) can actively initiate a drawing switching request (for example, the corresponding user clicks the drawing switching icon in the current display interface of the corresponding client) , And the drawing switch is controlled by the server.

In some embodiments, the client further includes:

The second request module is used to generate and send to the server a drawing switching request indicating that the local shared CAD drawing is switched in response to the drawing switching operation triggered by the corresponding user; wherein the drawing switching request includes the target CAD drawing mark information (drawing paper number) , Drawing path, etc.).

Correspondingly, in some embodiments, the server further includes:

The drawing switching module is used for responding to the drawing switching request sent by the client, and performing drawing switching for all clients connected to the server according to the target CAD drawing mark information in the drawing switching request.

Specifically, when the drawing switching module of the server receives a drawing switching request sent by any client, it first finds the corresponding target CAD drawing in the database of the server according to the target CAD drawing mark information therein, and then, the target CAD drawings are issued to each client for display. Of course, the target CAD drawing may also be sent when the client that initiates the drawing switching sends the drawing switching request.

Of course, after the server receives the drawing switching request, it can also forward the drawing switching request to other clients, and each client downloads the target CAD drawing from the server.

In some embodiments, the drawing switch request is usually initiated by the client corresponding to the active end.

Embodiment 8 The method of real-time discussion of CAD drawing sharing

The invention also provides an instant discussion method for CAD drawing sharing. Specifically, referring to Figure 6, the CAD drawing sharing instant discussion method includes the following steps:

S101: The server receives the operation data sent by the client, and synchronizes the operation data to at least one other client connected to the server.

In some embodiments, before performing step S101, the server needs to perform role assignment and permission configuration for at least two clients connected to the server. For example, the first client connected to the server is configured as the active terminal with real-time operation rights to the shared local shared CAD drawings, and accordingly, other clients connected to the server are configured as slaves, and The slave does not have the authority to perform real-time operations on the local shared CAD drawings.

Of course, in other embodiments, the server can also be configured as the active terminal according to the active application of the client, for example, any client connected to the server (triggered by its corresponding operating user) sends the service to the service When the client sends a request instruction to become the active terminal (for example, it means to become the "host"), the server configures it as the active terminal, and other clients automatically configure the slave terminal.

Correspondingly, after the role assignment and permission configuration are performed on each client, only the client corresponding to the active end that has real-time operation permissions on the local shared CAD drawings can send operation data to the server, and accordingly, the server Then the operation data is synchronized in real time to the slave without real-time operation authority.

In some embodiments, the client as the active end responds to the real-time operation of the local shared CAD drawing displayed by the user in the CAD drawing area of the current display interface (that is, currently shared), obtains the operating data of the corresponding operation, and sends The operation data is sent to the server in real time. Of course, in other embodiments, if all clients have real-time operation rights on the CAD drawing, the server can synchronize the operation data sent by any client to other clients in real time for synchronization processing. .

Among them, the local shared CAD drawing is pre-downloaded from the server. Of course, it can also be pre-stored on the client corresponding to the active end, and uploaded to the server by the client corresponding to the active end, and then the service The client sends it to the client corresponding to each slave.

Wherein, the real-time operation is the same as the real-time operation in each of the above embodiments, including the translation, enlargement and/or reduction of the local shared CAD drawing by the client corresponding to the user, and/or the addition or deletion of the local shared CAD drawing , Modify and/or filter comments.

S103: The server receives the communication information sent by any client, and instantly synchronizes the communication information to all other clients connected to the server, so as to perform synchronization processing in the current display interface corresponding to each other client.

In some embodiments, the communication information is a client (it can be a client configured as a slave or a client configured as an active end) in response to the corresponding user's communication operation in the instant messaging area of the current display interface (Such as input text data, picture data, etc.), obtain the communication information input by the user, and send it to the server immediately. Wherein, the communication operation includes an operation for the user to input discussion content in the instant communication area of the current display interface through an input device such as a keyboard or a touch screen.

During the discussion, any operating user can send a role switching request through its corresponding client to switch roles. Correspondingly, the method further includes the steps:

S105: In response to the role switching request sent by the client, the server sends a role switching control instruction to the target client according to the target client flag information in the role switching request, and performs the role according to the role switching response message fed back by the target client Switch.

In some embodiments, the role switching request is the client (which may be the client corresponding to the slave or the client corresponding to the active end) in response to the corresponding user in the current display interface (instant communication area or CAD drawing) When the role switching operation (such as clicking the corresponding role switching icon) triggered in the area), it is generated and sent to the server.

Among them, the role switching control instruction includes the unique identification information of the target client, such as an account number or a device number.

In some embodiments, if the client that initiates the role switching request is configured as the active end, the corresponding user of the client usually selects one of the multiple slaves as the new active end, and accordingly, the new active end The corresponding client is the target client; if the client that initiates the role switching request is a client configured as a slave, the target client is the client that initiates the role switching request.

Correspondingly, after receiving the role switching control instruction, the target client displays or reminds the corresponding user, and generates a corresponding role switching response message according to the selection of the corresponding user, and sends it to the server. Specifically, the role switching response message includes an instruction indicating acceptance/rejection of role switching.

In some embodiments, if the server receives a role switching response message from the target client (for example, the client whose original role is the slave) indicating that it accepts the role switching, the server directly sends the first client that initiated the role switching request (For example, the role of the client whose original role is the active end) is switched to the slave, and the role of the target client whose original role is the slave is switched to the active end, so that there is only the active end during the discussion period. Of course, if the server receives a role switching response message from a target client (such as a client whose original role is a slave) that refuses to perform role switching, the role switching response message is forwarded to the first client that initiated the role switching request At the end, when the first client receives the role switching response message, it may initiate a role switching request again.

During the discussion, the client of any operating user can generate a drawing switching request in response to the drawing switching operation triggered by the corresponding user to request the drawing switching. Correspondingly, the method further includes the steps:

S109: In response to the drawing switching request sent by any client, the server performs drawing switching according to the mark information of the target drawing in the drawing switching request.

In some embodiments, the drawing switching request is generated by the client in response to a drawing switching operation triggered by the corresponding user (such as clicking the corresponding drawing switching icon in the current display interface) and sent to the server.

In some embodiments, when the server performs drawing switching, the server uses the target drawing mark information (the target drawing mark information is previously entered by the client corresponding to the user that initiated the drawing switch request) in its database. The corresponding target drawing is found in the /storage module, and then it is automatically sent to each client (including the client that initiates the drawing switch), and then each client performs the drawing replacement locally.

Of course, in other embodiments, the server can also issue a drawing switch notification (including the download path of the target drawing), and then each client (including the client that initiates the drawing switch) downloads the target drawing according to the download path. Then replace the drawings locally.

Of course, in other embodiments, the target drawing may also be sent to the server when the client sends the drawing switching request, or the target drawing may be carried in the client/server in the drawing switching request. The storage path.

In some embodiments, when the server performs role permissions configuration, it can only open the drawing switch/role switching permissions to the active end, that is, only the user corresponding to the client configured as the active end can initiate a drawing switch request/role The user corresponding to the client configured as the slave does not have the authority to initiate a drawing switching request/role switching request, and can only initiate a drawing switching request/role switching request after the role switching becomes the active terminal.

During the discussion process, any client can respond to the disconnect sharing discussion operation triggered by the corresponding user to generate a disconnect request, so that the corresponding user can independently perform real-time operations on its own local CAD drawings, but not share it with other users Client. Correspondingly, the method further includes the steps:

S110: In response to a disconnect request sent by any client, the server configures the client that initiated the disconnect request as an autonomous terminal.

In some embodiments, the disconnection request is generated by the client in response to a disconnection operation (such as clicking a disconnection mode icon in the current display interface) triggered by the user in the current display interface, and sent to the server.

In some embodiments, in order to ensure the normal progress of the discussion, it is usually a client configured as a slave to initiate a disconnect request corresponding to the user. Of course, the corresponding user of the client configured as the active end can also initiate a disconnect request. At this time, the server will be configured as the active end and the client will be randomly selected from all the clients as the slave after disconnecting. It is configured as the new active end. Of course, the disconnect request sent by the client as the active end can also carry the target client identification information designated by the user as the successor to the active end. Therefore, when the server disconnects the active end client, it will be based on the target client's identifier. The information finds the target client from all clients that are slaves and configures it as the new master.

In some embodiments, the execution order of the above steps S101, S103, S105, S109, and S110 can be changed according to actual needs, or can be performed at the same time.
