Embodiment Construction

[0040] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0041] see Figure 1-14 , the present invention provides a technical solution: a high-precision pan-tilt control method based on subdivision driving, comprising the following steps:

[0042] Step 1. The DC-DC unit includes a DC-DC unit conversion circuit 1 and a DC-DC unit conversion circuit 2. The DC-DC unit converts the power required by each module and peripheral equipment according to the input power, and then controls the unit through the motorized lens. and the camera control unit are respectively externally connected with a motorized lens and a camera unit;

[0043] Step 2, configure the address and communication rate of the pan-tilt through the system param...

Abstract

The invention discloses a high-precision pan-tilt control and implementation method based on subdivision driving, and particularly relates to the technical field of pan-tilt control. An address and acommunication rate of a pan-tilt are configured through a system parameter configuration unit according to selection of a dial switch, and then, a universal PelcoD protocol is received through an RS485 communication unit to control the pan-tilt. According to the high-precision pan-tilt control and implementation method based on subdivision driving, through cooperation of the embedded micro-controlunit, the RS485 communication unit, the system parameter configuration unit and the stepping motor subdivision driving unit, subdivision driving of a stepping motor is adopted to achieve driving of the motor; and through the acceleration and deceleration algorithm of the motor and the switching algorithm of the subdivision data in the movement process of the motor, high-precision and stable control over the pan-tilt is achieved, and the requirements of the pan-tilt for the precision and stability of the pan-tilt in a special application scene are greatly improved.

Description

technical field [0001] The invention relates to the technical field of pan-tilt control, in particular to a high-precision pan-tilt control and realization method based on subdivision driving. Background technique [0002] The pan / tilt is a support device for installing and fixing the camera. It is divided into two types: fixed and electric. After reaching the best working posture, you only need to lock the adjustment mechanism. The electric pan / tilt is suitable for scanning and monitoring a large area. It can expand the monitoring range of the camera. The high-speed attitude of the electric pan / tilt is controlled by two executive motors. To achieve, the motor receives the signal from the controller to run and position accurately. Under the action of the control signal, the camera on the pan-tilt can not only automatically scan the monitoring area, but also track the monitoring object under the control of the monitoring center on duty. [0003] The accuracy and stability of...
