Locking tracking servo console with two degrees of freedom

Abstract

The invention discloses a locking tracking servo console with two degrees of freedom. The locking tracking servo console comprises a horizontal rotating part and a vertical rotating part, wherein thehorizontal rotating part drives a stand and a camera stand to horizontally rotate; and the vertical rotating part drives the camera stand to vertically rotate; an internal circuit of an infrared view-finding locking tracker is connected with motion control circuits of a horizontal direct current motor and a vertical direct current motor; a horizontal photoelectric encoder is coaxially connected with the horizontal direct current motor, and a horizontal rotating locating plate is mounted at a shaft end; a vertical photoelectric encoder is coaxially connected with the vertical direct current motor, and a vertical rotating locating plate is mounted at a shaft end; two groove-shaped optical couplers are fixed on the stand and respectively embedded on edges of the horizontal rotating locating plate and the vertical rotating locating plate; and a circuit board is mounted at one side of the stand. The locking tracking servo console with two degrees of freedom automatically locks a target, flexibly, continuously and stably tracks the target in real time in a full teaching and recording process and overcomes the defect of low motion accuracy by utilizing the feedback of the encoders and anopto-coupler closed loop; and the whole system has high-efficiency intelligence, symmetric appearance structure and reasonable gravity distribution.

Description

technical field

[0001] The invention relates to a pan-tilt system, in particular to a two-degree-of-freedom locking and tracking servo pan-tilt. Background technique

[0002] The pan / tilt is generally used to carry the camera, and realize the motion control of the camera through the motion control of the pan / tilt system. At the same time, the camera image is collected and transmitted to monitors, acquisition cards, hard disk recorders and other equipment. It is mostly used for teaching recording and installed in Classrooms, meeting rooms, etc. The existing pan / tilt system has a low degree of intelligence, cannot realize automatic tracking of the target, cannot meet the requirements of automatic target locking and automatic tracking and recording of the whole process of teaching; motion control has no closed-loop feedback, resulting in insufficient motion accuracy; the dial switch is installed inside On the main circuit board, it is inconvenient to adjust and increases the r...
