Description

Technical Field

[0001] The invention belongs to the technical field of video conferencing, and in particular relates to an assembled video conferencing device. Background Art

[0002] The video conferencing terminal is the core equipment of the video conferencing system. The video conferencing terminal establishes a one-to-one connection with all HOST terminals participating in the meeting. The HOST terminal is responsible for collecting the sound and image of the venue and then transmitting it to the video conferencing terminal. The video conferencing terminal determines the processing method and forwarding logic for audio, video and other signals according to the current video conferencing mode, and finally sends the processed audio and video data to each participant.

[0003] At present, since video conferencing terminals usually use automatic tracking cameras to track and shoot speakers, and since the lighting factors in different conference environments are different, when the automatic tracking camera is shooting under strong light, the automatic tracking camera is very likely to be overexposed due to excessive light input, resulting in the automatic tracking camera being unable to shoot the speaker normally, thereby interfering with the normal progress of the video conference.

The colors of the flexible filter films 540 are different, and the color depths of the flexible filter films 540 are arranged in sequence on the surface of the ring belt 530; a transparent protective glass 560 is embedded in the opening of the protective cover 520, and the size of the transparent protective glass 560 is larger than the lens size of the automatic tracking camera 510.

[0055] like Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the automatic drive component 550 includes a photosensitive controller 551 and four transmission shafts 552, the photosensitive controller 551 is embedded and installed inside the opening of the protective cover 520, the transmission shaft 552 is rotatably connected to the inside of the protective cover 520, and the transmission shaft 552 is transmission-connected to the inner side of the endless belt 530, one end of one of the transmission shafts 552 is fixedly connected to a micro servo motor 553 fixedly connected to the protective cover 520; the automatic drive component 550 also includes two transmission belts 554 symmetrically fixedly connected to both sides of the endless belt 530, the inner side of the transmission belt 554 is transmission-connected to four pulleys 555 respectively fixedly connected to the four transmission shafts 552, and the transmission shaft 552 does not contact the endless belt 530 and the flexible filter film 540;

[0056] like Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the camera mechanism 500 also includes a self-cleaning component 570, which includes an air guide cylinder 571 fixedly connected to the surface of the protective cover 520, one end of the air guide cylinder 571 is rotatably connected to a wind wheel 572, the surface of the wind wheel 572 is fixedly connected to a driven gear 573, the surface of the driven gear 573 is meshedly connected to a driving gear 574 fixedly connected to one of the transmission shafts 552; the circumference ratio of the driving gear 574 to the driven gear 573 is five to one; the surface of the air guide cylinder 571 is fixedly connected and connected to a protective shell 575, the opening of the protective shell 575 is embedded with a dustproof net 576, and the driving gear 57 4 and the driven gear 573 are both arranged inside the protective shell 575; the surface of the air guide cylinder 571 is fixedly connected and communicated with a uniformly distributed shunt pipe 577, and the opening of the shunt pipe 577 faces the transparent protective glass 560; the self-cleaning component 570 also includes a first one-way bearing 578 and a second one-way bearing 579, the first one-way bearing 578 is fixedly connected between one of the transmission shafts 552 and the adjacent pulley 555, and the second one-way bearing 579 is fixedly connected between one of the transmission shafts 552 and the driving gear 574, and the one-way blocking directions of the first one-way bearing 578 and the second one-way bearing 579 are opposite;

When the detection data is in a certain preset range and the data comparison is successful, it indicates that the light intensity at the lens of the automatic tracking camera 510 exceeds the corresponding value. The photosensitive controller 551 controls the micro servo motor 553 to rotate a specified number of circles according to the preset program. The micro servo motor 553 moves the specified flexible filter film 540 and covers it on the lens of the automatic tracking camera 510 through the transmission shaft 552, pulley 555, transmission belt 554 and endless belt 530 connected thereto, so as to ensure that the automatic tracking camera 510 can perform video operations within a reasonable lighting range, thereby achieving the purpose of expanding the scope of application of the automatic tracking camera 510.
