Problems solved by technology

[0006] However, as mentioned above, when the pan / tilt 200 used on the ceiling is shaken, the panning (PAN) control operation to rotate the surveillance camera in the horizontal direction, and the surveillance camera to rotate it in the vertical direction Due to errors in the panning (TILT) control operation, the problem that the monitoring performance is degraded due to the inability to correctly chase and shoot the irradiated object of the monitoring object often occurs

Embodiment Construction

[0023] Hereinafter, an embodiment of the method for compensating the vibration of the pan-tilt motor according to the present invention will be described in detail with reference to the accompanying drawings.

[0024] figure 2 According to the present invention, it is a schematic diagram showing the composition of the pan-tilt applicable to the vibration compensation method of the pan-tilt motor. It is composed of the following contents: panning in the horizontal direction (PAN) motor (PM) 2 0, panning in the vertical direction (TILT) motor (TM) 21, pan-tilt drive system 22, microcomputer 2 3, horizontal Directional pan (PAN) angle detection system 24, vertical direction pan (TILT) angle detection system 2 5 and port / interface system 2 6, meanwhile, acceleration sensor 2 7 and A / D conversion system (ADC) are added 28, etc., including the above content.

[0025] On the one hand, the above-mentioned acceleration sensor 27 is on the above-mentioned cloud platform 200, when it ...

Abstract

The invention relates to a vibration compensation method of a tripod head electric motor, which comprises the first step of utilizing a sensor in the tripod head to detect the present vibration values and the second step of causing the driving interference of the tripod head electric motor to be increased if the vibration values detected exceed the vibration permit values set by a machine. Under the circumstances that a camera for monitoring vibrates on a boarded pan / tilter, the invention utilizes an acceleration sensor, etc. to detect the corresponding vibration values, simultaneously, causes the torque of the tripod head electric motor to increase or the position of the cloud platform electric motor to initialize. For errors of the control and the operation of the tripod head, because prevention can be carried out before the errors happen, even if the vibration happens, the right tripod head control can be carried out.

Description

technical field [0001] The invention relates to a vibration compensation method for a pan-tilt motor. In particular, it means that the pan / tilter (Pan / Tilter) mounted on the surveillance camera can prevent panning (PAN) rotating in the horizontal direction and TILT in the vertical direction even if it vibrates. error, and proposed a vibration compensation method for the gimbal gimbal motor. [0002] Horizontal panning (PAN) and vertical panning (tilt) Background technique [0003] Generally speaking, when a PTZ surveillance camera with Pan / Tilt / Zoom (PAN / TILT / Zoom) skills is used, for example: on the ceiling of a specific place, etc., set it on the Pan&Tilter The place where it is carried, such as the attached figure 1 As shown, the monitoring camera 100 can change the monitoring image in other directions by the panning operation of the pan-tilt 200 rotating in the horizontal direction and the tilting operation of rotating in the vertical direction. [0004] Simultaneous...
