Sensor for indication of position of sound-generating moving objects

摘要

In the present invention, there is solved a circuit arrangement of a sensor for contactless indication of position of sound-generating moving objects. Information involving position is further conducted into an evaluating and registration device (most frequently a computer that further processes the sensed indications). A microphone and an acoustic pressure transducer (1) to electrical current are connected to input of a derivation circuit (2) that derives frequency to time. Then, there is the registration and evaluation device (3) with a time axis formed by a computer with corresponding software means. In this concrete embodiment, said device (3) with time axis is formed by an IBM personal computer compatible with software evaluating time dependence of the occupancy characteristic of a traffic detector by running motor vehicles.
