7. The camera signal device and system using optical fiber transmission according to claim 2, wherein: the movable wiper (16) is made of rubber materials, and the fluff pad (17) is made of animal hair materials.
8. The camera signal device and system using optical fiber transmission according to claim 2, wherein: the outer end of the movable rod (21) is fixedly connected with pulleys (2101), and the two pulleys (2101) are in sliding connection with the inner wall of the straight cylinder (19).
9. The camera signal device and system using optical fiber transmission according to claim 1, wherein: the outer end of the magnetic movable ball (15) is provided with a magnetic layer, and the magnetic layer is made of magnetic powder materials.
10. The use method of the camera signal device and system using optical fiber transmission according to any one of claims 1 to 9, wherein: the method comprises the following steps:
s1, imaging a lens (2) on a COMS chip (4), producing MIPI signals by the COMS chip (4), and transmitting the MIPI signals into an IC (8) through a circuit of a PCBA (3) so that the MIPI signals are converted into LVDS signals convenient for optical fiber communication;
s2, coupling a laser (7) into an optical fiber line (5) through a lens (6), coupling a control signal from an optical fiber to a photodiode (10), and transferring a signal of the photodiode (10) to a lens (2) to focus the lens;
s3, the dust screen (24) can block dust close to the lens (2), and the lens (2) works for a long time to release heat, so that the deformation memory capsule (12) expands when heated, drives the magnetic shielding powder to diffuse, cancels the magnetic shielding of the magnetic ball (13), attracts the two magnetic movable balls (15) to move, and collects and cleans the dust adhered to the dust screen (24).
