SYSTEM AND METHOD FOR DETECTING INTRUSION USING SMART KEY SYSTEM

摘要

PURPOSE: An intrusion detecting system and method are provided to determine the intrusion of a third party by sensing opening and damage of a car window through a smart key system. CONSTITUTION: An intrusion detecting system(100) comprises a controller(10), an LF(Low Frequency) transmitter, a LF receiver, and an alarm unit(60). The LF transmitter comprises an LF transmission antenna installed inside or outside a car. The LF transmitter transmits an LF signal including unique identifying information through the LF transmission antenna. The LF receiver comprises an LF receiving antenna installed inside or outside the car. The LF receiver detects the unique identifying information by receiving the LF signal. The LF receiver measures an LF signal level value and outputs it. The alarm unit generates an alarm to a car owner by receiving an alarm signal. The controller outputs the alarm signal to the alarm unit when the LF signal level value is over an LF signal level threshold.
