SURFING PHENOMENON PREDICTION SYSTEM AND SURFING PHENOMENON PREDICTION METHOD

摘要

PROBLEM TO BE SOLVED: To predict moving distance of a cable by a surfing phenomenon and give an alarm when the distance exceeds a given threshold value.;SOLUTION: A monitoring server comprises: prediction target area etc. formation means dividing a prediction target region and forming a plurality of prediction target areas and so on where at least one detection means is installed; basic data accumulation means including pipe line information, traffic information, and cable information; operation data accumulation means including temporal information about installation operation of a cable or correction operation of cable movement; moving distance estimation means having the relation between lapsed time obtained from the temporal information, the pipe line information, the traffic information and the cable information, and a cable moving distance as a function and estimating a cable moving distance estimation value of each cable from a function value obtained by the function and a cable moving distance detection value detected by the detection means; and monitor and alarm means monitoring the cable moving distance estimation value, and giving an alarm when the value exceeds a given threshold value.;COPYRIGHT: (C)2012,JPO&INPIT
