Abstract
The invention provides a self-detection method for a rotating mechanism control system in an airborne photoelectric detection device. The method comprises the self-detection of a control element, a control circuit board and the shafting friction moment uniformity. An angle measurement coded disc, a speed measurement gyro, a power supply board and a power amplifier board are provided with hardware self-detection signals. Whether the work is normal is judged by reading a hardware self-detection signal. A motor does not have a self-detection signal. On the basis of normal work of the angle measurement coded disc, the power supply board and the power amplifier board, a positive force is applied to the motor. If increased coded disc angle is detected, the motor is normally works. When the motor is detected, the coded disc differential speed is calculated in real time. If the differential speed of a position is less than a certain threshold, the friction torque of the position is too large. Through the detection method, whether all parts of the control system normally work can be quickly acquired, so as to timely carry out abnormal protection measures; the fault detection time is reduced; and the detection efficiency is improved.
