MOTION DETECTOR FOR MULTIPLE BUBBLE-LAYER DETECTION ZONES

摘要

The present invention relates to a bubble-type motion detector for multiple zones. The bubble-type motion detector for multiple zones comprises: a boundary bubble layer creation unit to transmit an output signal corresponding to a distance at which a boundary bubble layer is created to create boundary bubble layers at locations corresponding to multiples of the distance; and a signal analysis unit to analyze the output signal transferred from the boundary bubble layer creation unit and a reflection signal reflected from a moving body to check whether a moving body is present. According to the present invention, the boundary bubble layer creation distance and the number of boundary bubble layers can be arbitrarily adjusted to provide an easy installation environment, and an intensity of the reflection signal reflected from the moving body crossing the boundary bubble layers in multiple zones can be determined to accurately track a moving direction of the moving body.
