Problems solved by technology

[0006] The defect of this type of pan / tilt system is that the running speed of the motor cannot be closed-loop controlled during the rotation of the motor, and there will be phenomena such as torque ripple, so that the pan / tilt will vibrate during the operation, which will cause poor quality of the picture taken by the camera. The structure diagram is attached image 3

Abstract

The invention discloses an intelligent high-precision pan-tilt control system which comprises a motor, a multistage transmission mechanism, an incremental encoder, an absolute-type encoder and a single-chip microcomputer control circuit. The incremental encoder and the absolute-type encoder are equipped to the motor end and the output end of the multistage transmission mechanism respectively; the incremental encoder and the absolute-type encoder obtain the rotation speed of the motor and specific position of the multistage transmission mechanism in real time, and feed back the relevant parameters to the single-chip microcomputer control circuit in time; and the single-chip microcomputer control circuit carries out optimal control on the motor. The intelligent high-precision pan-tilt control system can realize closed-loop high-precision positioning and high smoothness operation of a camera pan-tilt control system in the operation process, thereby effectively preventing the case of overshoot or step out of the motor due to factors of driving method, machinery return difference or outside force abnormity and the like of the motor.

Description

technical field [0001] The invention relates to the field of pan-tilts, in particular to an intelligent high-precision pan-tilt control system. Background technique [0002] The pan / tilt is a supporting device for installing a fixed camera, and is generally divided into a fixed pan / tilt and an electric pan / tilt. The fixed pan / tilt is often used in occasions where the monitoring angle is not large, and the electric pan / tilt is suitable for scanning and monitoring a wide range of angles of view. This article describes a broadcast-grade electric pan / tilt. Traditional electric pan / tilts can usually be divided into two categories: [0003] 1. Only install the corresponding position detection encoder at the motor end or the input end of the transmission mechanism [0004] The defect of this type of pan / tilt system is that due to the influence of factors such as mechanical hysteresis and abnormal external obstructions, the repeat positioning accuracy of the pan / tilt is poor. The ...
