Description

Technical Field

[0001] The present invention relates to the field of photoelectric monitoring technology, and specifically to an anti-freezing and defrosting photoelectric bearing cabin and a photoelectric monitoring turntable. Background Art

[0002] In cold regions, optoelectronic monitoring equipment faces many challenges, one of which is the frost problem. When the temperature is below freezing, water vapor in the air condenses into frost and covers the lens of the monitoring equipment. This not only blocks the line of sight and affects the clarity of the monitoring image, but may also cause damage to the equipment, reducing its reliability and service life.

[0003] Specifically, frost problems can cause the following effects:

[0004] Blurred vision: Frost will cover the surveillance lens, blocking light from entering, causing the surveillance image to become blurred. This will seriously affect the effectiveness of the surveillance system, making it unable to accurately capture and record the details of the target object.

[0005] Optical distortion: The uneven thickness of the frost layer on the lens will cause light refraction and reflection, resulting in optical distortion. This will cause the surveillance image to be deformed, have color aberration, and other problems, further reducing the surveillance quality.

[0006] Equipment damage: If the frost accumulates too thickly on the lens, it may increase the pressure on the lens surface and even damage the lens. In addition, frost may also affect the electronic components inside the device, causing circuit short circuits, component aging and other problems, reducing the stability and reliability of the device.

[0007] In view of this, it is necessary to develop and design a photoelectric cabin that can prevent freezing and defrost fog. Summary of the invention
