[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. A broadcast adjustment component is provided. During the broadcast, the various fixed screens and movable screens are spliced ​​into a large screen for display. If there is a need to interpret the key points of the news, the host walks near any movable screen and pauses. The camera shoots the host's position, and the console of the rear controller controls the horizontal electric push rod at the corresponding position to push the movable screen out. At this time, the adjustment motor drives the mounting frame with the movable screen to rotate so that the movable screen faces the host, making it convenient for the host to explain and demonstrate. After the content is demonstrated, the host moves away, the movable screen is reset, and the demonstration is carried out in conjunction with other fixed screens and movable screens;

[0023] During the broadcast process, according to the content, the electric push rod can be started and adjusted to drive the end tubes and movable frames connected to the connecting shaft to move at the same time, so that the movable frames on both sides gather towards the middle, and the fixed display screen and movable display screen corresponding to the movable frame move and surround the outside of the host, and multiple related news are broadcast at the same time to further improve the broadcast effect. In the above-mentioned broadcast adjustment process, the brightness sensor always detects the brightness of the broadcast and adjusts the unfolded area of ​​the reflective cloth at all times to ensure that the brightness is always within the appropriate range during the broadcast, and automatically adjusts to ensure the broadcast effect. Different broadcast methods are used under different broadcast conditions, and diversified broadcasts improve the display effect. In conjunction with an external intelligent control system and a multi-scene preset module, dynamic content display of the background screen, fast scene switching and linkage with the lighting and camera system can be realized.

[0024] 2. A cooling protection component is provided. If the fixed display screen and the movable display screen are overheated, the air pump and the super wave atomizer are started. The super wave atomizer atomizes the water in the water tank, and the air pump draws the water mist into the air collecting box through the air supply pipe, and then sprays it into the folding airbag. Because the adhesive plate is bonded to the back of the fixed display screen and the movable display screen, the temperature of the fixed display screen and the movable display screen is transferred to the folding airbag through the thermal pad, and the water mist will enter the connected folding airbags along the corrugated pipe. The heat is transferred to the water mist and finally discharged from the bottom of the right-angle exhaust pipe, reducing the temperature of the fixed display screen and the movable display screen. The water mist does not directly contact the fixed display screen and the movable display screen. The cooling effect is good while ensuring safety, ensuring that the fixed display screen and the movable display screen can operate efficiently for a long time.

[0025] In summary, when the movable frames on both sides of the broadcast adjustment component rotate, the folding airbags of the cooling protection component at the corresponding position also unfold and move at the same time, and the folding curtain unfolds and the bellows deforms to prevent debris from entering the box body composed of the fixed baffle box and the movable baffle box while maintaining the smooth flow of water mist. While the two work independently, they work together to ensure that the broadcast adjustment component can perform better and have a better use effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] The working principle and use process of the present invention are as follows: before the news broadcast begins, the display surfaces of the fixed display screen 203 and the movable display screen 211 are all flush, and the fixed display screens 203 and the movable display screens 211 are spliced ​​into a complete large screen. The winding motor 220 is started, and the winding motor 220 drives the winding shaft 221 to rotate and unwind. The wire motor 230 is started, and the wire rope 228 is pulled to be wound on the spool 229, and the end rod 224 is driven to slide along the straight guide port 226. The wire rope 228 and the reflective cloth 222 are always in a taut state. Then, the light strip 225 is powered on, the brightness sensor 219 receives the brightness and transmits the model to the rear console with a controller. The reflective cloth 222 reflects light to the large screen where the fixed display screen 203 and the movable display screen 211 are spliced. The light blocking film 223, the fixed light blocking plate 217 and the movable light blocking plate 235 jointly block the surrounding area of ​​the large screen to reduce light interference in other locations. The area of ​​the reflective cloth 222 is adjusted until the brightness is appropriate to ensure a better presentation effect during the news broadcast, completing the preparations before the broadcast.

[0048] During the broadcast, the fixed display screens 203 and the movable display screen 211 are spliced ​​into a large screen for display. If there is a need to interpret the key points of the news, the host walks near any movable display screen 211 and stops walking. The camera 218 shoots the host's position, and the console of the rear controller controls the horizontal electric push rod 207 at the corresponding position to push the movable display screen 211 out. At this time, the adjustment motor 209 will drive the mounting frame 210 on which the movable display screen 211 is installed to rotate, so that the movable display screen 211 faces the host, which is convenient for the host to explain and demonstrate. After the content is demonstrated, the host moves away, and the movable display screen 211 is reset to cooperate with other fixed display screens. 203 and the movable display screen 211 are used for demonstration. During the presentation, the electric push rod 216 can be activated and adjusted according to the content to drive the end tube 212 connected to the connecting shaft 213 and the movable frame 202 to move simultaneously, so that the movable frames 202 on both sides gather towards the middle, and the fixed display screen 203 and the movable display screen 211 corresponding to the movable frame 202 move and surround the outside of the host, and multiple related news are presented at the same time, further improving the presentation effect. In the above-mentioned presentation adjustment process, the brightness sensor 219 always detects the brightness of the presentation and adjusts the unfolded area of ​​the reflective cloth 222 at all times to ensure that the brightness is always within the appropriate range during the presentation. The automatic adjustment ensures the presentation effect.

[0049] During a long period of continuous broadcasting, both the fixed display screen 203 and the movable display screen 211 will generate heat. If the fixed display screen 203 and the movable display screen 211 are overheated, the air pump 307 and the super wave atomizer 310 will be started. The super wave atomizer 310 will atomize the water in the water tank 309, and the air pump 307 will draw the water mist into the air collecting box 306 through the air supply pipe 308, and then spray it into the folding air bag 302. Because the adhesive plate 304 is bonded to the back of the fixed display screen 203 and the movable display screen 211, the temperature of the fixed display screen 203 and the movable display screen 211 is transferred to the folding air bag 302 through the thermal pad 303, and the thermal spring The presence of 305 and the heat-conducting ring 314 accelerates the transfer of heat. The temperature inside the folding airbag 302 is relatively high, and the water mist is not easy to liquefy. The water mist will enter the connected folding airbags 302 along the bellows 315, and the heat will be transferred to the water mist and finally discharged to a distant place from the bottom end of the right-angle exhaust pipe 311, so as to avoid the water mist interfering with the progress of news broadcasting, reduce the temperature of the fixed display screen 203 and the movable display screen 211, and cool down by water mist, but the water mist does not directly contact the fixed display screen 203 and the movable display screen 211. The cooling effect is good while ensuring safety, ensuring that the fixed display screen 203 and the movable display screen 211 can operate efficiently for a long time.

[0050] When the movable frames 202 on both sides of the studio adjustment component 2 rotate, the folding airbags 302 of the cooling protection component 3 at the corresponding position also unfold and move, and the folding curtain 313 unfolds and the bellows 315 deforms, preventing debris from entering the box body composed of the fixed baffle box 205 and the movable baffle box 206 while maintaining the smooth flow of water mist. While the two work independently, they work in conjunction to ensure that the studio adjustment component 2 performs better and has a better performance.

[0051] At the same time, the system combines image processing algorithms and real-time rendering technology to quickly load preset scenes or generate dynamic background images in real time according to program requirements. The system supports multi-screen splicing and partition display functions, and can simultaneously display news content, data charts and real-time videos on the same background screen;

[0052] The brightness and color of the background screen can also be automatically adjusted according to the on-site environment through linkage control with the studio lighting system, ensuring that the picture effect is consistent with the overall atmosphere of the studio, thereby improving the visual expression and production efficiency of the news program.

[0053] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or substitute equivalents for some of the technical features. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
