Description

Technical Field

[0001] The invention relates to a data interaction system, in particular to a data interaction system based on domestic digital design software. Background Art

[0002] As a mature and popular technology, CAD technology has been widely used in enterprises, covering almost all industries. It is more obviously and prominently used in industries such as machinery, construction, and clothing, and has become the actual productivity of enterprises. The CAD market is full of opportunities around the improvement of enterprises' innovative design capabilities and the popularization of network computing environments.

[0003] After decades of development, domestic CAD technology has also made great progress. Domestic CAD software refers to CAD software products independently developed by my country. Currently, domestic CAD software on the market includes Haochen CAD, Zhongwang CAD, Weiheng CAD, etc.

[0004] Usually, when using domestic CAD for model design, it is done independently by a single designer. In the process of independent model design, a single designer will eventually have limitations in thinking. Involving multiple designers in model design will break through the limitations of thinking, achieve the collision of sparks of thought, and be more conducive to the rapid and effective completion of the project.

[0005] Traditionally, designers from multiple parties are invited to attend a meeting at a designated time and place to discuss and modify the current plan. However, sometimes designers are separated from each other, and it is very difficult to invite designers from all over the world to attend a meeting at a designated place.

[0006] How to develop a data interaction system based on domestic digital design software, breaking through traditional methods and allowing designers in different regions to use modern network communication technology to discuss and modify the current design model in real time, is a technical problem that needs to be solved.

[0043] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly understood.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0046] like Figure 1 As shown, the present invention discloses a data interaction system based on domestic digital design software, which includes: a host computer device 10, an inviter computer device 20, a host mobile communication device 30, and an inviter mobile communication device 40.

[0047] The inviter's computer device 20 remotely controls the host's computer device 10 through computer remote control software. Specifically, the host's computer device 10 includes a computer host and a display; the inviter's computer device 20 includes a computer host and a display.

[0048] like Figure 1 As shown, in this embodiment, there is one host computer device 10 and multiple inviter computer devices 20; one of the multiple inviter computer devices 20 remotely controls the host computer device 10 through computer remote control software. It can be understood that in this embodiment, one host invites multiple inviters to participate in the event at the same time.

[0049] In other embodiments, there is one host computer device 10 and one inviter computer device 20. It can be understood that in this embodiment, one host only invites one inviter to participate in the activity, that is, a one-to-one connection.

[0050] The host's mobile communication device 30 and the inviter's mobile communication device 40 are connected by video call software. Specifically, the host's mobile communication device 30 is a mobile phone or a tablet computer; the inviter's mobile communication device 40 is a mobile phone or a tablet computer.

[0051] In this embodiment, the number of the inviter mobile communication devices 40 corresponds to the number of the inviter computer devices 30. It can be understood that one inviter only includes one inviter computer device 30 and one inviter mobile communication device 40 corresponding thereto.

[0052] Next, the method of using the data interaction system based on the domestic digital design software is described (eg Figure 1 shown):

[0053] The computer device 10 of the main conference attendee needs to be installed with domestic digital design software, such as Haochen CAD, Zhongwang CAD, Weiheng CAD, etc. Only after the relevant domestic digital design software is installed can the corresponding technical drawings be opened;

[0054] The host computer device 10 of the host and the inviter computer device 20 need to install computer remote control software, such as the "Sunflower Remote Control Software" of the prior art;

[0055] After the host installs the computer remote control software, he / she will get the "local identification code" and "local verification code" when he / she opens the computer remote control software.

[0056] The host tells the "local identification code" and "local verification code" on the host's computer device 10 to other inviters;

[0057] After one of the other inviters has installed the computer remote control software on his / her inviter computer device 20, he / she opens the computer remote control software, enters the obtained "local identification code" into the "partner identification code" column, enters the obtained "local verification code" into the "partner verification code" column, and clicks "remote assistance" to remotely control the host computer device 10 of the host, for example, to modify the drawings on the host computer device 10;

[0058] At the same time, both the host's mobile communication device 30 and the inviter's mobile communication device 40 need to install video call software, such as the "WeChat APP" of the prior art, through which multiple parties can realize online video calls at the same time;

[0059] It should be noted that the host computer device 10 of the host can only be controlled by the inviter computer device 20 of one of the inviters (if any other inviter needs to control, the current inviter needs to exit the control and the other designated inviter logs in through the computer remote control software). The inviter can fully control the host computer device 10. The host and the designated inviter can clearly see the current operation process through their respective display screens, while other inviters cannot see the current operation process through their own display screens because they do not have control rights.

[0060] In order to solve the above technical problems, the present invention is specially equipped with a host mobile communication device 30 and an inviter mobile communication device 40 to realize multi-party simultaneous online video calls, so that the host and all inviters can see the current operation process at the same time and can have conversations and discussions.

[0061] The above-mentioned data interaction system based on domestic digital design software will also encounter such a technical problem during use:

[0062] During a multi-party video call, one party needs to adjust the shooting angle of the communication device in a timely manner so that the other party can see the content that the party wants to show; Figure 2As shown, for example, for the host, he needs to adjust the shooting angle of the host's mobile communication device 30, and adjust the shooting angle between the display 11 and the table 12, so that the host's mobile communication device 30 can shoot the content on the display 11, or the host's mobile communication device 30 can shoot the files on the table 12; for another example, for the inviter, he needs to adjust the shooting angle of the inviter's mobile communication device 40, and adjust the shooting angle between his own face and the table 12, so that the inviter's mobile communication device 40 can shoot his own facial expression, or the inviter's mobile communication device 40 can shoot the files on the table 12.

[0063] In order to solve the above problems, the data interaction system based on domestic digital design software of the present invention further includes a video switching device 50 (such as Figure 2 shown).

[0064] The main conference participant's mobile communication device 30 is installed on the video switching device 50;

[0065] The inviter's mobile communication device 40 is installed on the video switching device 50 .

[0066] like Figure 3 and Figure 4 As shown, specifically, the video switching device 50 includes: a table 100 , a bracket 200 , a rotating rod 300 , and a clamping claw 400 .

[0067] The bracket 200 is slidably mounted on the table 100 in the horizontal direction. The bracket 200 includes a fixed sleeve 210 and a lifting column 220. The lifting column 220 is slidably mounted in the fixed sleeve 210 in the vertical direction. One end of the rotating rod 300 is rotatably mounted on the lifting column 220, and the clamping claw 400 is mounted on the other end of the rotating rod 300. The mobile communication device 30 of the host is mounted on the clamping claw 400; the mobile communication device 40 of the inviter is mounted on the clamping claw 400.

[0068] Furthermore, the video switching device 50 further includes an angle adjustment limiting mechanism 500 (such as Figure 5 shown).

[0069] Among them, Figure 6 As shown, the angle adjustment limit mechanism 500 includes: a base 510 , a positive adjustment limit magnetic knob 520 , and a reverse adjustment limit magnetic knob 530 .

[0070] like Figure 7 and Figure 8As shown, the base 510 is a sleeve structure with two ends opened, and the base 510 has a forward knob mounting end 511 and a reverse knob mounting end 512. The forward adjustment limit magnetic knob 520 is magnetically adsorbed and unidirectionally rotated on the forward knob mounting end 511, and the reverse adjustment limit magnetic knob 530 is magnetically adsorbed and unidirectionally rotated on the reverse knob mounting end 512. The unidirectional rotation direction of the forward adjustment limit magnetic knob 520 is opposite to the unidirectional rotation direction of the reverse adjustment limit magnetic knob 530.

[0071] like Figure 7 and Figure 8 As shown, a limit plate 310 is provided on the rotating rod 300, and the limit plate 310 is rotatably arranged in the sleeve of the base 510 and clamped between the forward adjustment limit magnetic knob 520 and the reverse adjustment limit magnetic knob 530; a forward limit block 311 and a reverse limit block 312 are respectively provided on the two end faces of the limit plate 310, and a forward limit arc groove 521 cooperating with the forward limit block 311 is opened on the forward adjustment limit magnetic knob 520, and a reverse limit arc groove 531 cooperating with the reverse limit block 312 is opened on the reverse adjustment limit magnetic knob 530.

[0072] like Figure 7 and Figure 8 As shown, in this embodiment, the forward knob mounting end 511 and the forward adjustment limit magnetic knob 520 cooperate with each other through a ratchet pair; the reverse knob mounting end 512 and the reverse adjustment limit magnetic knob 530 cooperate with each other through a ratchet pair.

[0073] Next, the method of using the above-mentioned video switching device 50 is described:

[0074] At the host's place, the host's computer device 10 and the video switching device 50 are placed on the desktop where the host works. The host places the host's mobile communication device 30 on the clamping claw 400;

[0075] At the inviter's place, the inviter's computer device 20 and the video switching device 50 are placed on the desk where the inviter works. The inviter places the inviter's mobile communication device 40 on the clamping claw 400;

[0076] Adaptive adjustment is performed on the video switching device 50:

[0077] One hand twists the mobile communication device on the clamping claw 400 so that the camera on the mobile communication device is aimed at the current display screen. At this time, the angle of the mobile communication device has been pre-positioned (the hand needs to remain in the current position temporarily to prepare for the subsequent final positioning); when the clamping claw 400 is twisted, the rotating rod 300 rotates accordingly, and the rotating rod 300 further drives the limit plate 310 to rotate, and the positive limit block 311 on the limit plate 310 reaches the specified position;

[0078] The other hand rotates the forward adjustment limit magnetic knob 520. The forward adjustment limit magnetic knob 520 rotates in one direction on the forward knob mounting end 511 but cannot rotate in the reverse direction. When the forward adjustment limit magnetic knob 520 feels resistance during the rotation (the resistance comes from the blocking of the forward limit arc groove 521 by the forward limit block 311), the rotation of the forward adjustment limit magnetic knob 520 is stopped.

[0079] In this way, the angle of the camera on the mobile communication device to the display screen (one's own face) has been adjusted, and the two hands can be separated from twisting the clamping claw 400 and positively adjusting the limit magnetic knob 520;

[0080] Similarly, one hand reversely twists the mobile communication device on the clamping claw 400 so that the camera on the mobile communication device is aimed at the current table 100. At this time, the angle of the mobile communication device has been pre-positioned (the hand still needs to remain in the current position temporarily to prepare for the subsequent final positioning); when the clamping claw 400 is twisted, the rotating rod 300 rotates accordingly, and the rotating rod 300 further drives the limit plate 310 to rotate, and the reverse limit block 312 on the limit plate 310 reaches the specified position;

[0081] The other hand rotates the reverse adjustment limit magnetic knob 530. The reverse adjustment limit magnetic knob 530 rotates in one direction on the reverse knob mounting end 512 but cannot rotate in the reverse direction. When the reverse adjustment limit magnetic knob 530 feels resistance during the rotation (the resistance comes from the blocking of the reverse limit arc groove 531 by the reverse limit block 312), the rotation of the reverse adjustment limit magnetic knob 530 is stopped.

[0082] In this way, the angle of the camera on the mobile communication device toward the table 100 has been adjusted, and the two hands can respectively disengage and twist the clamping claw 400 and reversely adjust the limit magnetic knob 530;

[0083] It can be seen that the clamping claw 400 and the mobile communication device thereon can rotate within a limited range; for example, when the clamping claw 400 is rotating in the forward direction, when the forward limit block 311 on the limit plate 310 reaches the limit position of the forward limit arc groove 521, it will be blocked and cannot move forward. At this time, the camera on the mobile communication device is already in place and aimed at the display screen (one's own face); for another example, when the clamping claw 400 is rotating in the reverse direction, when the reverse limit block 312 on the limit plate 310 reaches the limit position of the reverse limit arc groove 531, it will be blocked and cannot move forward. At this time, the camera on the mobile communication device is already in place and aimed at the table 100;

[0084] It can be seen that as long as the clamping claw 400 and the mobile communication device thereon are rotated forward or reversely at will, when the clamping claw 400 obviously senses resistance and cannot continue to rotate, it means that it has been rotated to the right position, and the camera on the mobile communication device can realize fast and accurate switching of different scenes;

[0085] It should be further explained that, no matter whether it is the host or the inviter, the environment they are in is different, and the video switching device 50 needs to be adjusted according to the specific situation (the rotation angles of the cameras on the mobile communication devices are different). Only by making adjustments in advance can the cameras on the mobile communication devices focus accurately and clearly, and can quickly switch between different scenes (display screen, one's own face or desk); wherein, there are documents or draft papers placed on the desk, and the current person can show the contents of the documents to other people, or use a pen to draw and calculate on the draft paper, etc.

[0086] It should be supplemented that, in the present invention, the bracket 200 is slidably arranged on the table 100 in the horizontal direction, and the lifting column 220 is slidably sleeved in the vertical direction and can be fixedly arranged in the fixed sleeve 210. In this way, the camera on the mobile communication device can be adjusted horizontally and vertically, and the camera can be focused accurately and clearly in combination with the aforementioned angle adjustment.

[0087] The video switching device 50 of the present invention also has the following design features:

[0088] A positive adjustment limit magnetic knob 520 and a reverse adjustment limit magnetic knob 530 are specially designed. The positive adjustment limit magnetic knob 520 and the reverse adjustment limit magnetic knob 530 can be magnetically attached to the positive knob mounting end 511 and the reverse knob mounting end 512, respectively. In addition, the positive adjustment limit magnetic knob 520 is magnetically attached and unidirectionally rotated on the positive knob mounting end 511, and the reverse adjustment limit magnetic knob 530 is magnetically attached and unidirectionally rotated on the reverse knob mounting end 512. Such a structural design is very beneficial for accurately adjusting the angle.

[0089] For example, in the process of rotating the positive adjustment limit magnetic knob 520, the positive adjustment limit magnetic knob 520 is tightly adsorbed on the positive knob mounting end 511 by magnetic force and rotates unidirectionally. In the process of rotation, the positive adjustment limit magnetic knob 520 is not only unable to rotate in the opposite direction, but more importantly, the positive adjustment limit magnetic knob 520 is not easy to separate from the positive knob mounting end 511, which makes the positive adjustment limit magnetic knob 520 rotate "step by step" (no jumping occurs between the teeth on the ratchet pair), and finally makes the limit position of the positive limit arc groove 521 abut against the positive limit block 311, so as to achieve accurate adjustment;

[0090] In addition, after the positive adjustment limit magnetic knob 520 is rotated and adjusted, the positive adjustment limit magnetic knob 520 is tightly adsorbed on the positive knob mounting end 511 by magnetic force and will not be separated, thus forming a stable positioning. In the subsequent use process, when the positive limit block 311 collides with the limit position of the positive limit arc groove 521, the positive adjustment limit magnetic knob 520 will not rotate in the opposite direction or be separated.

[0091] Furthermore, the forward adjustment limit magnetic knob 520 and the reverse adjustment limit magnetic knob 530 of the present invention can be flexibly removed from the forward knob mounting end 511 and the reverse knob mounting end 512 and then reinstalled to achieve reset, which facilitates the angle adjustment of the entire video switching device 50 again.

[0092] In the present invention, a video switching device 50 is provided, and one of its major features is that the rotation range of the camera on the mobile communication device is positioned in advance. Since the extreme position of the rotation has been determined, the effect of quickly and accurately switching the shooting scene can be achieved during the subsequent use.

[0093] In the present invention, one end of the rotating rod 300 passes through a bearing 301 (such as Figure 5 The rotating rod 300 is rotatably arranged on the lifting column 220. By arranging the bearing 301, the rotating rod 300 can be subjected to force more stably during the rotation process.

[0094] In the present invention, a paper placement slot 101 (such as Figure 4 By providing the paper placement slot 101, the document or paper can be accurately placed in place, which is conducive to the camera on the mobile communication device to quickly and accurately shoot.

[0095] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
