摘要:
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; 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.
