Abstract: Provided are a loop type automobile sensing device formed integrally with a small loop coil, which has the automobile sensing sensitivity of a related art loop type automobile sensing device using a large loop coil, so as to greatly facilitate installing and maintaining of the loop type automobile sensing device and to expand the application scope of the loop type automobile sensing device, and a parking information system using the loop type automobile sensing device. In addition, the loop type automobile sensing device integrally formed with the loop coil is provided in plurality as automobile sensors to detect the presence and moving state of an automobile according to a signal from the automobile sensors, to control operations of a plurality of cameras, warning lamps, and display devices installed to a parking lot, and to notify parking information and automobile movement information.

Abstract: The present invention relates to a low power operated loop type vehicle detecting apparatus, and particularly, to a low power operated loop type vehicle detecting apparatus that comprises an LC resonator with a loop coil installed in a detecting area, a resonance oscillation circuit unit, and a vehicle behavior determination unit. The vehicle detecting apparatus further comprises: a behavior determination clock generator for generating a behavior determination clock; a count controller for setting clock count time in a steady-state period; a behavior determination clock counter for counting the behavior determination clock during the clock count time set by the count controller; and a vehicle behavioral state determiner for determining a vehicle behavioral state in a detecting area, based on the counting value of the behavior determination clock counter. Power consumption can thereby be reduced.
