Technical problems and advantages solved by the invention
In the invention, each terminal (including the master terminal and the slave terminal) can carry out instant messaging while looking at the picture. And the CAD drawings can be conveniently and rapidly checked at any time when all parties of the CAD cooperative work exchange discussions.
A user of a plurality of terminals (including a driving terminal and a driven terminal) simultaneously watches one CAD drawing, and changes on the CAD drawing can be shared in real time. For example: after a user A (as a master terminal) opens a drawing at the terminal of the user A, a user B and a user C (as slave terminals) can see the opened drawing at the respective terminals at the same time. When the user a performs operations such as enlarging, reducing, translating and the like on the viewport of the drawing, the CAD drawings on the interfaces of the respective terminals of the user B and the user C also change along with the operation of the user a. Therefore, the communication pertinence of each terminal is stronger, clearer, more definite and higher in efficiency. Especially, compared with the technical scheme of sharing the drawing by depending on a web browser, the method adopts the local CAD drawing sharing module to receive the operation data, synchronously displays the operation according to the operation data, and has stronger processing capacity and calculation capacity.
In the aspect of CAD drawing sharing, each terminal of the invention displays the locally cached CAD drawing and is a vectorized graphic display (instead of displaying the CAD drawing by using a dot matrix picture and a video). Therefore, in the invention, the user of each terminal sees the CAD vectorized graph which is clearly displayed and meets the requirements of engineering drawings.
In addition, the changes and operations (such as adding annotations, moving a laser pen, and operating the enlargement, reduction, and translation of a viewport of the CAD drawing) on the CAD drawing are transmitted through parameters, so that the operation of synchronously displaying the CAD drawing of the master terminal on the CAD drawing of the slave terminal is realized. Therefore, in the invention, the real-time transmission through the network is not the screen capture and/or video data, not the whole CAD drawing, but the operation data, so that the synchronization speed of the CAD drawing in each terminal in the real-time discussion process is high, and the real-time performance is strong.

Embodiment 1 sharing chat graph operating system
The shared chat picture operating system comprises an instant messaging module (communication modes of instant messaging comprise drawings, characters, voice, pictures, videos and the like) and a CAD drawing sharing module.
The shared chat picture operating system can run on a PC end platform and/or a mobile communication equipment end platform.
The invention provides an operating system for simultaneous instant messaging and synchronous shared discussion of CAD drawings by multiple persons, which can realize the operation of one terminal (namely a 'driving terminal' or an 'operating terminal' 100), and the change of the CAD drawings on the driving terminal or the operating terminal 100 can be synchronously displayed by other connecting terminals (namely a 'driven terminal' or a 'display terminal' 102) in real time.
In some embodiments, when a multi-person shared chat is performed, a target file (e.g., a CAD drawing) to be discussed is uploaded on the server 104, and the first user terminal entering the shared chat conference is the active terminal 100 by default. The active terminal 100 downloads the object file from the server 104, and the server 104 identifies and records the object file downloaded by the active terminal. Thereafter one or more terminals entering the conference of discussion are automatically identified as slave terminals 102. When the slave terminal 102 enters the conference, the server 104 sends a file download request or provides a file download link to the slave terminal 102, and guides the slave terminal user 102 to download the same target file (which is identified and recorded by the server 104) from the server 104 as the master terminal 100.
Of course, in other embodiments, the target file to be discussed may come from the master terminal 100, and the master terminal 100 first uploads the target file to the shared server 104 for downloading by each slave terminal participating in the conference discussion. In other embodiments, the active terminal 100 may not be configured in the joining order, but rather, one of the terminals in question may be selected as the active terminal 100. In the present invention, the roles of the terminals are not fixed, the authority of the master terminal 100 may be handed over to the slave terminal 102 (that is, the roles of the master terminal and the slave terminal are exchanged), and the slave terminal 102 may be selected to become the master terminal 105 without being controlled by the master terminal 100.
After the terminal 100, 102 obtains the target file to be discussed, the file is stored locally in the terminal, and is opened through the CAD drawing sharing module of the terminal, and the terminal enters the page shown in fig. 2, which includes a CAD drawing display area and an instant messaging area, where the two areas may be distributed on the terminal display interface up and down or left and right, or may be distributed on the terminal display interface in an overlapping manner (for example, the instant messaging area floats on the CAD drawing display area).
Specifically, terminal a in fig. 2 is master terminal 100 and terminal B, C, D is slave terminal 102. The active terminal 100 and the slave terminal 102 can communicate with each other through an instant messaging area, and the communication mode includes drawings, characters, voice, pictures and/or videos. The master terminal 100 operates the opened CAD drawing in the CAD drawing display area 132a, the slave terminal 102 obtains the operation parameters on the master terminal 100 through the server 104, and the slave terminal performs the operation adapted to the device according to the operation parameters. In some embodiments, the instant messaging module of each terminal performs message transmission through the server (e.g., chat messages sent by the a terminal through the instant messaging module are uploaded to the messaging server and then sent to the instant messaging module of the B, C, D terminal). In some embodiments, the operating parameters for the CAD drawing are also transmitted between the terminals through the server. Please note that, the communication information and the operation parameters may be transmitted by the same server or different servers.
In some embodiments, the slave terminal 102 may synchronize annotation with the master terminal 100, and specifically, the master terminal 100 annotates and explains (i.e., adds annotation data) a certain part of the CAD drawing display area, and the content of the annotation data may include text, lead lines, sketches, voice, pictures, and the like (136a, 138 a).
These annotation data are stored separately from the source data of the CAD drawing. The server 104 receives the annotation data from the master terminal 100 and then transmits the annotation data to the slave terminal 102 in real time, and the slave terminal 102 performs synchronous processing on the local CAD drawing of the slave terminal 102 (i.e., adding the annotation data 136b, 138b) according to the received annotation data. Similarly, when the annotations of the master terminal 100 are changed (new, modified, deleted, etc.), the slave terminal 102 also receives the changed annotation data (through the server) in real time and makes synchronous changes to the annotations according to the changed annotation data.
By realizing synchronous display of the annotations, a user of each terminal can clearly see at which point and/or entity the discussion on the CAD drawing is specifically performed, and can immediately see the essential contents (such as characters, lead lines, sketches, voice and pictures) of the annotations, so that the discussion situation can be more accurately understood, and the discussion efficiency is improved.
In addition, when the slave terminal realizes the synchronous display of the annotations according to the technical scheme, no matter the annotation data is added, or the annotations are newly created and modified, the slave terminal carries out the localization operation under the local software and hardware environment according to the received operation data.
In some embodiments, the master terminal 100 and the slave terminal 102 may implement viewport (viewport) synchronization. Specifically, when the active terminal 100 performs operations such as zooming in or zooming out or translation on the viewport of the CAD drawing, the operations are actually changes of two corner points of the viewport, that is, the viewport is operated. When the active terminal 100 amplifies, reduces and translates the CAD drawing of the display area of the CAD drawing, the position of the initial corner point changes, the new corner point coordinates are transmitted to the slave terminal 102 through the server 104, and the slave terminal 102 automatically adjusts the viewport to the new coordinates after obtaining the new coordinates, so as to realize viewport synchronization. For example, the initial two corner coordinates of the master terminal 100 are (x1, y1), (x2, y2), after the viewport operation, the corner coordinates are changed to (x3, y3), (x4, y4), the server 104 receives the new coordinates and transmits the new coordinates to the other slave terminals 104, and after the new coordinates are obtained by the other slave terminals 104, the self viewport is adjusted to (x3, y3), (x4, y 4). In this way, the view port of the slave terminal 104 can be synchronized with the master terminal 100.
One reason the present invention enables fast and smooth viewport synchronization is that each terminal of the present invention displays CAD vector graphics paper source data that is cached locally at the terminal, rather than pictures and video transmitted in a video conference or screen sharing (e.g., screen sharing of QQ). Specifically, each terminal (including the master and slave terminals) calls the same CAD drawing on the server 104, and in order to improve the operation performance, the CAD drawing on the server is actually downloaded to the local cache, and each terminal opens the CAD drawing of the local cache. Therefore, in the present invention, the local CAD drawing can be opened at each terminal according to the actual conditions (software and hardware configuration) of each terminal, and the change/operation can be displayed on the local CAD drawing in synchronization with receiving the change/operation data from the active terminal. That is, when the driven terminal implements synchronous display of the view ports according to the above technical solution, both the translation of the view ports and the zooming-in and zooming-out of the view ports are localized operations performed by the driven terminal in a local software and hardware environment according to the received operation data.
In some embodiments, the master terminal 100 implements laser pointer 140a synchronization with the slave terminal 102. Specifically, the master terminal 100 activates the laser pointer 140a for CAD drawing position indication, the system will display the laser pointer 140a at the default initial position (x0, y0) on the CAD drawing of the CAD drawing display area, and simultaneously pass (x0, y0) to each slave terminal 102 through the server 104, each slave terminal 102 will also display the laser pointer 140b at (x0, y0) of the CAD drawing display area. At this time, the active terminal point 100 picks up the laser pen 140a for dragging, the position of the laser pen 140a is changed to (x1, y1), the new position laser pen data (x1, y1) is transmitted to the slave terminal 102 through the server 104 in real time, and the slave terminal 102 moves the laser pen 140b from (x0, y0) to (x1, y1) by itself, 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 technical scheme, the slave terminal performs the localized operation in the local software and hardware environment according to the received operation data, no matter the display of the laser pen or the movement of the laser pen.
In some embodiments, the default is that the first terminal entering the conference is the master terminal 100, and the subsequent terminals entering the conference are the slave terminals 102. In some embodiments, the active terminal 100 selects a new active terminal from the list of members entering the shared chat diagram through the "host change" function in the shared chat diagram system of the present invention. After the authority of the active terminal is handed over, the CAD drawing does not change, the new active terminal can do the above operations (for example, annotating the CAD drawing, amplifying, reducing and translating the viewport of the CAD drawing, operating the laser pointer indication position on the CAD drawing) after the active terminal is handed over, and the CAD drawing can be replaced by using the function of viewing other drawings in the group.
In some embodiments, the slave terminal 102 selects to disconnect the CAD drawing sharing with the master terminal 100 (i.e., enter the autonomous viewing state from the "drawing sharing state"), the disconnected slave terminal 102 (i.e., the autonomous terminal 105) can still use the instant messaging areas (134a, 134b) displayed by the instant messaging module 200 of the terminal to know the discussion situation, but the CAD drawing displayed in the CAD drawing display area on the autonomous terminal 105 is no longer controlled by the master terminal 100, so that the CAD drawing on the own terminal can be operated autonomously, and even the CAD drawing displayed on the own terminal can be replaced. In other words, the slave side 102 after disconnecting the drawing sharing module 204 is no longer controlled by the master side 100. In some application scenarios, such functions are important, some cooperative users already obtain the information they want after participating in the partial discussion, and need to autonomously annotate and/or modify the local CAD drawing on their terminal as soon as possible — the invention allows the CAD user of the slave terminal to choose to quit the discussion (i.e., choose not to share the CAD drawing synchronously with the master terminal), and will not affect other slave terminals. In addition, because the CAD drawing which is actually cached locally is opened on the slave terminal 102 in the present invention, and the displayed CAD drawing is displayed according to the local condition of the slave terminal 102, when the slave terminal switches from the shared drawing state to the self-viewing state, the interface of the CAD drawing display area does not have a large jump, and continuous smooth switching can be realized. In other words, the view port of the CAD drawing does not change due to mode switching, and the user experience is better.
After the discussion of one CAD drawing is completed, the active terminal 100 may select to switch the CAD drawing to continue the discussion, or select to end the discussion conference. The annotation data added to the CAD drawing during discussion may be stored in the source data of the CAD drawing, or may be stored separately from the source data of the CAD drawing (but remain associated so that when the CAD drawing is viewed again, all annotations are displayed on the CAD drawing), and the source data of the CAD drawing may be stored in the server 104, or may be stored at a local location of each terminal for further discussion or viewing.
In the shared chat system of the present invention, all operation processes performed by the master terminal 100 in the CAD drawing display area 132a are converted into operation commands (commands)/operation data by the server 104 and sent to the slave terminal 102, so that the display content in the CAD drawing display area 132b of the slave terminal 102 is synchronized with the master terminal 132 a. Because only the operation instruction is transmitted between the master terminal 132a and the slave terminal 132b, the data amount to be transmitted is effectively controlled, thereby reducing the burden of the network, and avoiding the situations that the display of the CAD drawing in the CAD drawing display area 132b in the slave terminal 102 is prolonged and jammed in the conference discussion process, and the like, which are caused by large network load.
Embodiment 2 sharing chat graph operation method
The invention also provides an operation method for simultaneously carrying out instant messaging and synchronous shared discussion of the CAD drawings by a plurality of persons, which can realize the operation of one terminal (namely an active terminal or an operation terminal) and the operation method for synchronously displaying the change of the CAD drawings of the operation terminal in real time by other connection terminals (namely driven terminals), and solves the technical problems of inconvenient communication, incapability of synchronously discussing and explaining in real time and the like when the CAD drawings are drawn by a plurality of persons in a coordinated manner. In some embodiments, the following steps may be included:
step one, uploading the CAD drawing to be discussed to a server 104, setting a first user terminal entering the shared chat system conference as an active terminal 100, and then sending a request to the active terminal 100 to guide the active terminal 100 to download the CAD drawing to be discussed from the server 104. In some embodiments, the CAD drawing to be discussed is initially stored locally at the active terminal 100, in which case the user of the active terminal 100 uploads the CAD drawing to be discussed to the server 104 for downloading by the slave terminal 102 in subsequent steps.
And step two, the server 104 identifies the CAD file downloaded from the active terminal 100, and marks and records the CAD file. And after other terminals enter the conference, the default of the terminals is the slave terminal, the server sends a downloading request to the slave terminal, and the slave terminal downloads the CAD drawing file which is the same as that of the master terminal.
Step three, the active terminal 100 and the slave terminal 102 respectively open the locally stored CAD drawing file source data, namely, the CAD drawing sharing module 204 is started, and CAD drawing display areas (132a, 132b) are displayed on the terminal interface; meanwhile, the terminal starts the instant messaging module 200, and displays instant messaging areas (134a, 134b) on the terminal interface, so that each terminal can browse drawings and exchange information at the same time.
And fourthly, the active terminal 100 operates the CAD drawings of the CAD drawing display areas (132a, 132b), such as adding annotations, adjusting view ports, moving a laser pen, and the like, while the slave terminal 102 acquires the operating parameters of the active terminal 100 through the server 104, and then makes corresponding changes according to the operating parameters and the configuration conditions of the local device, so as to perform synchronous operation on the locally cached CAD drawings of the slave terminal 102.
Further, in order to more efficiently realize multi-person interaction, the active terminal 100 and the slave terminal 102 in the system may be PC terminals or various types of mobile terminals (smart phones, tablet computers, notebook computers, vehicle-mounted computers, etc.).
Further, during the discussion, the active terminal 100 and the slave terminal 102 are switched, and the active terminal 100 may select a new host from the member list entering the current shared chat conference through a "host changing" function in the shared chat system. After the authority of the active terminal is handed over, the CAD drawings displayed by each terminal cannot be changed (because the CAD drawings are stored locally), so that the problems of display interface jumping, unsmooth switching and the like cannot occur at each terminal. After the transfer is completed, the new active terminal may perform the above operations such as adding annotations, adjusting the view port, moving the laser pointer, etc. on the CAD drawing in the CAD drawing display area 132a, or may replace the CAD drawing with the function of viewing other drawings in the group.
Further, during the discussion, the CAD drawing sharing module 204 between part of the slave terminal 102 and the master terminal 100 is disconnected to become the master terminal 105, but the master terminal 105 can continue to use the instant messenger module 200. The disconnected slave terminals 102 will no longer follow the master terminal 100 to synchronously operate on the CAD drawings, and the user disconnecting the slave terminal 102 can independently operate the local CAD drawings of the user, and can even replace the local CAD drawings with other CAD drawings, but can still see the ongoing discussion content in the instant messaging area 134. In some application scenarios, such functions are important, some cooperative users already obtain the information they want after participating in the partial discussion, and need to make their own comments and/or modifications on the local CAD drawing at their terminals as soon as possible — the CAD user of the slave terminal can choose to quit the discussion (i.e. choose not to synchronize with the master terminal), and will not affect other slave terminals.
In some embodiments, the master terminal 105 may reconnect with the master terminal in a subsequent operation to become the slave terminal 102 again, or obtain control from the master terminal 100 to become a new master terminal 100, and upload the CAD drawing source data that is locally modified and stored to the server, and then transfer the CAD drawing source data to each slave terminal to become a new discussion object.
