A brief introduction to the internal structure of the high-precision gimbal
What is the internal structure of the high-precision gimbal? First of all, let's start with the purpose of the high-precision gimbal. The high-precision PTZ is a supporting device for installing and fixing the camera, which can ensure that the camera can move in four directions, up, down, left, and right, to obtain a larger viewing angle. The function and function of the monitoring PTZ is to support the adjustment of the focal length, depth of field, and aperture of the camera to obtain better image capture effects at any time.
The high-precision gimbal protective cover provides a suitable working environment for the camera and lens, and can realize the horizontal and vertical adjustment of the shooting angle. The PTZ decoder converts the digital signals from the control terminal into electrical signals to drive the PTZ to operate. The decoder is the core equipment of the gimbal and lens control. It can be used to control the lens and gimbal through the software through the computer interface. After the camera is installed on the fixed gimbal, the camera's pan and tilt angles can be adjusted to achieve the calibrated angle. , this is the monitoring function and function of the high-precision PTZ.
The high-precision pan/tilt carries the camera to rotate in both horizontal and vertical directions. The high-precision pan/tilt is equipped with two motors, one of which is responsible for horizontal rotation and the other for vertical rotation. The angle of horizontal rotation is generally 360 degrees infinite rotation, and the vertical rotation is 30 degrees, 45 degrees, 60 degrees and so on. The angle of horizontal and vertical rotation can be adjusted by limit switches. Its overall working voltage generally has AC 24V, AC 220V and DC 24V. When the upper and lower action voltages are received, the vertical motor rotates, and the vertical drive wheel is driven to rotate through the reduction box; when the left and right action voltages are received, the horizontal motor rotates and drives the horizontal gear plate at the bottom of the gimbal to rotate through the reduction box. . The high-precision gimbal has horizontal and vertical limit bolts, and the gimbal has two micro switches to realize the limit function. When the rotation angle reaches the preset limit bolt, the micro switch acts to cut off the power supply, and the high-precision gimbal stops rotating.
