The present invention provides a system to filter the malfunction of a security fence by using a shielding multicore cable, capable of analyzing environmental effects and preventing a warning caused by the malfunction, through noise prediction. To this end, the system comprises: a signal analyzing part outputting measurement data, including a frequency characteristic, by analyzing a charge electrified in the shielding multicore cable; a management server extracting noise pattern data from the measurement data, detected by signal analyzing part since a random past moment, extracting environmental noise data, made by modeling the extracted noise pattern data from environmental data received by an environmental information detecting part, extracting noise prediction pattern data by referring to the extracted environmental noise data, controlling a determination boundary through the extracted noise prediction pattern data, and determining signals, inputted from the signal analyzing part, as a noise signal and a trespassing signal through classification by the controlled determination boundary; and the environmental information detecting part detecting environmental data around the signal analyzing part to output the data to the management server. Therefore, the present invention is capable of preventing a wrong warning by filtering malfunction through noise prediction by natural phenomena such as wind and seasons. |
