Abstract
The invention relates to the field of power monitoring and particularly relates to a recognition and elimination method for unidentified objects in a power monitoring system. The method comprises collecting images in the power monitoring system, calculating the number of pixels in each frame of image, comparing the number with the number of a standard image, and determining whether unidentified objects intrude into the power monitoring system; performing far infrared thermal imaging detection if unidentified objects intrude and classifying the unidentified objects. If the unidentified objects are living bodies, a central processor sends signals to a local controller and a position detector, the local controller controls the power grid of a smallest area of the unidentified objects to be disconnected, and the position detector drives a manipulator to move to the current positions of the unidentified objects to eliminate the unidentified objects; if the unidentified objects are not living bodies, the central processor sends signals to the position detector to drive the manipulator to remove the unidentified objects. According to the method, the unidentified objects in the power monitoring system can be discriminated and eliminated to safety areas timely, and the method is simple and rapid.
