Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pan-tilt cameras, in particular to a double-spectrum heavy-duty pan-tilt camera based on harmonic technology. Background Art
[0002] With the development of long-distance and large-scale video surveillance technology, dual-spectrum heavy-duty PTZ is increasingly used in forest fire prevention, border and coastal defense, fishery administration, ship-borne and other fields.
[0003] Based on the above, the inventors found the following problems: When facing complex environments and diversified high demands such as long distance, long-term operation, and high speed, the existing dual-spectrum heavy-duty pan / tilt transmission technology is mostly worm gears, which mainly have the following disadvantages:
[0004] 1. It is impossible to obtain higher dynamic characteristics. Its positioning speed is mostly 30-40° / s, which cannot meet the requirements in situations where fast positioning and linkage tracking are required.
[0005] 2. The worm gear has a large mechanical gap and is difficult to adjust. Usually the mechanical gap is 0.1°-0.2° or even larger. If you want to further reduce the mechanical gap, you need high-precision processing technology and materials, which is costly. The monitoring scenes of dual-spectrum heavy-duty PTZ cameras are mostly long-distance and large scenes. Often, a 0.1° mechanical error will cause a 50% screen offset or even a larger deviation on the image, making it impossible to align the monitoring scene.
[0006] 3. The worm gear is a direct meshing of mechanical teeth, which will wear out and lose powder after long-term operation. On the one hand, it will further increase the mechanical clearance. On the other hand, the fallen metal powder may enter the camera lens or fall on the circuit board, causing damage to the electronic circuit board or components.
[0007] Therefore, in view of this, the existing structure and deficiencies are studied and improved, and a dual-spectrum heavy-duty pan-tilt camera based on harmonic technology is provided, in order to achieve a purpose with greater practical value. Utility Model Content
