Abstract:
    The invention supplies the method and structure used rotating type pyroelectric detector to identify static and motive human body. The method includes the following steps: connecting the electric machine with the pyroelectric detector, making the pyroelectric detector form relative velocity difference with the static human body or motive one by forward and backward alternating turning the electric machine. Thus the pyroelectric detector of the invention can identify static and motive human body, meanwhile enlarge detector monitoring range, and improve the defect that the detector is not sensitive to the radial motive human body. The invention can be widely used in electric theft-proof, human body detecting, safety auto protecting control field etc, and supply a brand new application visual angle for lithium tantalite pyroelectric detector.
