(2) The front-end main control module sends a driving instruction to the air pump controller, and the air pump controller drives the air pump to pump the air in the air storage tank and jet the air to the dust collecting plate so as to remove dust adsorbed on the dust collecting plate;
(3) The front-end main control module sends a driving instruction to the liquid pump controller, the liquid pump controller drives the liquid pump to pump liquid in the liquid storage tank and jet liquid to the camera mirror surface, the camera mirror surface is cleaned for the second time, and meanwhile, the liquid pump controller obtains the residual liquid volume in the liquid storage tank through the liquid level sensor and sends the residual liquid volume to the upper computer;
(4) The terminal host control module sends a driving instruction to the mirror surface heating controller, the mirror surface heating controller drives the heating wire to electrify and heat, and the heating wire dries and dehumidifies the mirror surface of the camera.
2. The method of claim 1, further comprising switching between the main camera lens and the standby camera lens, and comprising:
(1) After the mirror surface of the camera is cleaned, the main camera performs video shooting operation, and video data is sent to an upper computer for display;
(2) If the user judges that the video quality displayed by the upper computer does not reach the standard, judging that the main camera has a problem, and sending a main and standby camera switching instruction to the upper computer;
(3) The upper computer sends a main and standby camera switching instruction to the camera controller, and the camera controller switches the main camera lens and the standby camera lens.
3. The method for using the coordinated video surveillance device for automatically removing the foreign matters on the mirror surface according to claim 1 or 2, wherein two groups of imaging lenses are arranged in the camera, namely a main imaging lens and a standby imaging lens, and the main imaging lens and the standby imaging lens are electrically connected with a camera controller.
4. The method for using the linked video monitoring device for automatically removing the mirror surface foreign matters according to claim 1 or 2, wherein the front-end communication module is a fiber channel.
5. The method of claim 3, wherein the front-end communication module is a fiber channel.
