To further improve an axle counting device that is operable in a range where a required security level is secured rather than making a uniform train-on-rail determination even if a fault occurs in axle detection.SOLUTION: The number Bo of advancing axles, the number Bi of approaching axles, and the number Ba of passing axles or the number Co of advancing axles, the number Ci of approaching axles, and the number Ca of passing axles are obtained for every end part based on detection results A1, A2 of a plurality of axle detectors of each of section end units 10 in each end part in an object section on a railroad track. The number Ba of passing axles is adopted as the adopted axle number on the basis of them if abnormality further occurs in each end part while the number Ci of approaching axles is adopted if each end part is normal. Then, a difference Δ between the adopted axle number (Ba or Bi, Ci) and the number (Bo, Co) of advancing axles is calculated and a train-on-rail state is determined according to whether or not the difference is "0".SELECTED DRAWING: Figure 1

    【課題】車軸検出に不具合があっても一律に在線判定が出されるのでなく必要な保安度が確保される範囲で動作しうる車軸計数装置を更に改良する。【解決手段】線路の対象区間の各端部の区間端ユニット10夫々の複数の車軸検出子の検出結果A1,A2に基づいて端部毎に進出車軸数Boと進入車軸数Biと通過車軸数Baや進出車軸数Coと進入車軸数Ciと通過車軸数Caを求め、それらに基づいて更に端部毎に異常なら採択車軸数に通過車軸数Baを採択し正常なら進入車軸数Ciを採択し、それから採択車軸数(Ba又はBi,Ci)と進出車軸数(Bo,Co)との差Δを算出し、それが“0”か否かで列車在線状態を判別する。【選択図】 図1
