ABNORMALITY DETERMINATION DEVICE, DATA TRANSMISSION DEVICE, AND ABNORMALITY DETERMINATION SYSTEM
PROBLEM TO BE SOLVED: To determine whether or not an abnormality is occurring in a rail without using a track circuit and without performing peak frequency analysis.SOLUTION: An acquisition part 111 acquires a signal according to a power generation amount measured by a power generator 2 from a terminal 12. A calculation part 113 specifies the number of axle passages by analyzing a change in the power generation amount acquired by the acquisition part 111 to detect a peak of the power generation amount, and calculating the number of detected peaks. An integration part 112 integrates the power generation amount acquired by the acquisition part 111 over a period until the number of axle passages reaches a prescribed number. A determination part 114 determines whether or not there is an abnormality in a rail 3 based on an integrated value transmitted by the integration part 112.
【課題】軌道回路を使わず、かつピーク周波数分析を行わずにレールに異常が生じているか否かを判定する。【解決手段】取得部１１１は、発電装置２で計測された発電量に応じた信号を、端子１２から取得する。計数部１１３は、取得部１１１が取得した発電量の変化を解析することで、この発電量のピークを検知し、検知したピークの数を計数することによって、車軸通過数を特定する。積算部１１２は、車軸通過数が規定数に達するまでの期間にわたって、取得部１１１が取得した発電量を積算する。判定部１１４は、積算部１１２により伝えられた積算値に基づき、レール３の異常の有無を判定する。【選択図】図６
