Outdoor pan-tilt camera anti-icing structure and control method

Abstract

The invention relates to an outdoor pan-tilt camera anti-icing structure. The outdoor pan-tilt camera anti-icing structure comprises a pan-tilt shell, a protection cover shell and a main shaft. The main shaft is transversely arranged on the pan-tilt shell in a rotating mode. The protection cover shell is fixedly arranged at one end of the portion, outside the pan-tilt shell, of the main shaft. An anti-icing mechanism controlled by a control unit is arranged in the gap between the pan-tilt shell and the protection cover shell. The anti-icing mechanism comprises a rotating wheel, a brushing disc and bristles, wherein the rotating wheel is arranged between the side wall of the pan-tilt shell and the main shaft in a rotating mode, the brushing disc is coaxially and fixedly arranged on the side wall of the rotating wheel, the bristles are fixedly arranged on the outer side end face of the brushing disc, the end portions of the bristles make contact with the side wall of the protection cover shell, and the rotating wheel rotates to drive the bristles to rotate. The control unit is connected with a temperature and humidity detection unit and a weight detection unit. The outdoor pan-tilt camera anti-icing structure is simple in structure and scientific and reasonable in design, the icing problem of the gap between a pan-tilt and the side wall of a protection cover is effectively solved, it is ensured that the pan-tilt camera can normally work all day long, and performance of the product is effectively improved.

Description

technical field [0001] The invention belongs to the field of video security monitoring, in particular to an anti-icing structure and control method of an outdoor pan-tilt camera. Background technique [0002] Outdoor PTZ cameras, especially double-sided PTZ cameras, such as figure 1 As shown, two shields 3 are carried on both sides of the pan / tilt 1, one of which is used to place a camera for capturing images; the other is used for placing an auxiliary light source structure for night vision monitoring. Because the contact surface 2 between the cloud platform and the protective cover is relatively large, and the gap is small, snow accumulation is easy to accumulate in the gap, especially in the western region where the temperature difference is large, the temperature difference between day and night is large, and the snow accumulation in the gap is very easy. Melt the ice. Furthermore, the current pan-tilt camera operates at a low frequency during all-day monitoring. It is ...

Problems solved by technology

[0004] The anti-icing method of the above-mentioned outdoor dome camera is a method of anti-icing through the temperature sensor combined with the control unit of the pan / tilt. , but in practical application, this method will affect the normal video monitoring of the pan / tilt, and the process of repeatedly rotating the original position of the pan / tilt will produce position accumulation errors. The more times the above process is repeated, the greater the error will be
