Embodiment Construction

[0014] The high-precision positioning pan / tilt includes a horizontal rotation platform and a vertical rotation platform as well as a horizontal drive motor, a vertical drive motor and a controller. Such as image 3 As shown, the horizontal rotating platform includes a cylindrical base 1 and a rotating platform 2, and the wall height of the cylindrical base 1 should be appropriate so as not to affect the activities of the camera 3 on the vertical rotating platform. The bottom of the base 1 is provided with a circle of inner gear ring 4, and the center position of the inner gear ring 4 on the bottom of the tube is provided with a bearing. The rotating platform 2 is disc-shaped. There is a fixed central shaft 5, the central shaft 5 can be made into a tubular shape, and a number of cut grooves are arranged along the pipe wall to make the pipe wall have a certain elasticity. It is connected to the rotary platform 2 in the bearing hole, and a gap is provided at the position matchin...

Abstract

The invention relates to a high-precision positioning rotational station, comprising a horizontal rotating platform, a vertical rotating platform, a horizontal driving motor, a vertical driving motor and a controller. The controller comprises a power supply unit, a data communication circuit, a control unit and a motor drive unit. The high-precision positioning rotational station is characterizedin that the control unit comprises a data processing unit, a real-time longitude and latitude memory, a positioning longitude and latitude memory and a comparator. Because of the arrangement of the real-time longitude and latitude memory, the positioning longitude and latitude memory and the comparator, a control center can send out final positioning longitude and latitude information of the horizontal rotating platform and the vertical rotating platform and can continuously send out the information for more than one time for improving the reliability, and the controller of the rotational platform can control the horizontal driving motor and the vertical driving motor to work after the comparison of the comparator to obtain a relative longitude and latitude position only by receiving the final positioning longitude and latitude once, thereby improving the measurement precision and the reliability of the high-precision positioning rotational station.

Description

technical field [0001] The invention relates to a high-precision positioning cloud platform. Background technique [0002] The pan / tilt is a device that installs and fixes the camera to rotate horizontally and vertically. It is used to scan and monitor a large area and expand the monitoring range of the camera. It is widely used in security monitoring equipment. The pan / tilt is usually equipped with a horizontal rotation platform and a vertical rotation platform, as well as two motors and a controller. One of these two motors is responsible for the rotation in the horizontal direction, and the other is responsible for the rotation in the vertical direction. The controller receives the control signal from the remote control center, and the two motors receive the signal from the controller to run and position precisely. Under the action of the control signal, the camera on the pan / tilt can automatically scan the monitoring area, and can also track the monitoring object under...
