Abstract

The invention provides a fluctuation angle compensating system. The fluctuation angle compensating system comprises a driving system, a control system and a measuring system; the driving system comprises a driving motor, a small belt pulley and a large belt pulley; the effective load is fixedly connected with the large belt pulley and synchronously rotates with the large belt pulley; when in use, the working location of the effective load is set; the measurement system measures the fluctuation angle of the effective load in case of fluctuation at the location of the effective load, and the fluctuation angle value is transmitted to the control system; the control system calculates a compensating angle according to the fluctuation angle and controls the driving motor to reversely rotate in the compensating angle so as to return the effective load to the set working location. With the adoption of the fluctuation angle compensating system, the fluctuation angle speed in the visual axis direction of the load can be effectively isolated, and thus the stability of imaging in the visual axis direction can be improved, and the stabilizing precision is relatively high; the stabilizing platform has a wide application prospect in the fields of film, police application and military.

Description

technical field [0001] The invention relates to a disturbance angle compensation system, which is suitable for multi-axis camera stabilization platforms such as ground, vehicle, airborne, shipborne, and spaceborne, and can be extended and applied to military, police, film and television and other fields according to user needs . Background technique [0002] Gyro stabilization technology not only has important applications in the fields of precision strikes in the military field, day and night reconnaissance, target monitoring and tracking, but also in aerial photography, aerial search and rescue, customs anti-smuggling, public security patrols, etc. areas are also gaining more and more attention. With the increasing application of gyro stabilization technology, there are more and more requirements for the function and stability accuracy of the stable platform. Although the loads carried by different carriers such as airborne, vehicle-mounted, ship-borne and space-borne ar...
