Problems solved by technology

[0004] The technical problem to be solved by the present invention is: in the prior art, during the rotation of the pan / tilt, the motor is always driven according to the designated locking torque (the designated locking torque is greater than the maximum value of the required locking torque of the motor under various postures), This will inevitably cause unnecessary power loss and energy waste, poor environmental protection performance, and does not conform to my country's basic national policy of energy conservation and emission reduction

Embodiment Construction

[0056] The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings and examples, so as to fully understand and implement the process of how to apply technical means to solve technical problems and achieve technical effects in the present invention. It should be noted that, as long as there is no conflict, each embodiment and each feature in each embodiment of the present invention can be combined with each other, and the formed technical solutions are all within the protection scope of the present invention.

[0057] Before elaborating each specific embodiment in detail, the structure of the pan-tilt mechanism is briefly described first. The pan-tilt mechanism mainly includes a base, a horizontal motor, a pan-tilt seat, a vertical motor, a first bracket and a second bracket. Specifically, the pan platform seat is rotatably arranged on the upper surface of the base through the rotating shaft, the output shaft of th...

Abstract

The invention discloses a method and system for driving a pan-tilt motor. The method comprises the steps of obtaining relative angular displacement of an output shaft of the motor relative to a zero point position; determining the minimum locking torque corresponding to the relative angular displacement according to a preset first motor load curve; determining self-locking torque of the motor and making the self-locking torque greater than the minimum locking torque; and driving the motor according to the self-locking torque. The method and the system can meet effective support on a camera to a certain extent, can effectively reduce the power consumption, achieve the targets of energy conservation and emission reduction, are good in environmental protection capability and conform to the basic state policy of energy conservation and emission reduction of our country.

Description

technical field [0001] The invention relates to the technical field of pan-tilt control, in particular to a method for driving a pan-tilt motor and a system for driving a pan-tilt motor. Background technique [0002] Today, as the security industry continues to mature, various PTZs or PTZ cameras continue to appear. In order to monitor various angles of the site with different attitudes (that is, horizontal angles and vertical angles), the pan / tilt includes a horizontal motor and a vertical motor. In order to keep the camera still at a certain attitude, it is necessary to provide sufficient self-locking torque to the horizontal motor and / or vertical motor. [0003] For a horizontal motor or a vertical motor, in the prior art, the motor is usually driven according to a certain fixed locking torque, so as to realize fixed-point monitoring from all angles of view. Specifically, in the prior art, first determine the locking torque required by the motor in each posture, and the...
