Abstract: PURPOSE: An invasion alarm apparatus using optical fiber is provided to eliminate the installation of a loop shaped optical fiber, to install a transmitting part and a receiving part at a same position, and to improve a signal processing efficiency. CONSTITUTION: The invasion alarm apparatus using optical fiber comprises an optical fiber as an optical passage media installed at a boundary of a corresponding monitor region; a light source generating part for generating coherent optical signal to incident it via the one end of the optical fiber; a mirror for reflecting the light emitted from the other end of the optical fiber; an optical coupler for diverging the progress direction of the optical signal; an auxiliary optical fiber(150) at a passage media of the diverged optical signals; a light receiving part for receiving the optical signals from the distal end of the auxiliary optical fiber to convert it into an electric signal; an amplifier, a low pass filter part, and an electric wave purifying part for amplifying the converted electric signal successively and purifying a noise signal; and a comparing part and an alarm part for comparing the purified signal with a standard signal and generating a result.

Abstract: PURPOSE: A method for sensing an invasion and a method for classifying an invading object by using an optical fiber are provided, which is applied to various industry fields by identifying the invading object into a person or vehicle. CONSTITUTION: A method for sensing an invasion by using an optical fiber includes: a first step(S1) of converting the signal sensed at the monitoring system into a digital signal; and a second step(S10) of determining whether the invasion is occurred or not in response to the summation value by summing(S5-S9) all of the sample data while sliding the time window for the converted digital signal sample data.
