step 3, when the image collected by the image sensor (23) deviates from the center and is deflected to the upper and lower sides, the up-down rotating unit (3) starts to work, the first electric push rod (32) works to push the N-shaped frame (33) to move up and down, so that the steering block (35) is driven to rotate, the angle of the camera (26) arranged on the steering block (35) is adjusted, and the following image collection is carried out in the same way;
step 4, when the image transmitted to the image sensor (23) is fuzzy, the image sensor (23) starts to control the cleaning protection unit (5) to work, the second electric push rod (53) works to drive the connecting plate (56) to move back and forth so as to drive the fixing shaft (54) arranged on the connecting plate (56) to move, the fixing shaft (54) is sleeved with a tension spring (55), and a cleaning pad (57) fixed on the fixing shaft (54) is close to the lens (58) under the action of the tension spring (55), so that cleaning and wiping can be carried out until the cleaning is finished;
step 5, when the image sensor (23) senses that the object is rapidly amplified, the cleaning protection unit (5) is controlled to work, and the connecting plate (56) rapidly covers the lens (58) to protect the lens (58) and prevent the lens (58) from being damaged by the object and causing the result that information cannot be transmitted;
and 6, when the monitoring visual field needs to be adjusted greatly, only the total visual field adjusting unit (4) needs to be moved downwards, the pulling piece (41) is moved downwards, the rotating frame (48) is driven to move downwards, the rotating frame (48) drives the rotating base (43) to slide on the guide shaft (42), a first guide block (45) and a second guide block (46) are fixed on the rotating base (43), at the moment, the second guide block (46) is in contact with the guide rod (47) under the action of pulling force, so that the rotating frame (48) completes 45-degree rotation, then the pulling piece (41) is released, the spring is reset, the rotating base (43) is driven to move upwards, the rotating base (43) drives the first guide block (45) to move upwards, and similarly, the 45-degree rotation is completed, and the 90-degree rotation of the whole device can be realized.
