To realize an axle counter capable of operating in a range in that necessary security degree is assured and that on-rail determination is not produced evenly even with an unsatisfaction in an axle detection.SOLUTION: An advance axle number Bo, an approach axle number Ba and a passing axle number Ba are calculated based on a detection result A1, A2 of a plurality of axle detector of each section end unit 10 of each end part of the section of object of a railway and an exit difference Δ2=[Ba+Ca-2×(Bo+Co)]or[Ba+Ca-Bo-Co]is calculated and a train on-rail state is determined based on whether the exit and entry difference Δ2 is "0" etc or not.In addition, an entry and exit difference Δ1=[Bi+Ci-Bo-Co]is also calculated and the train on-rail state is determined based on whether the exit and entry difference Δ1 is "0" etc or not.In addition a changeover part 44 is also arranged and it performs a determination based on the exit and entry difference Δ1 in a normal state and it performs a determination based on an exit and entry difference Δ2 in the case of a failure of an axle detector 11 and other emergency.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実現する。【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を求めて、通出差Δ2=[Ba+Ca−2×(Bo+Co)]又は[Ba+Ca−Bo−Co]を演算し、通出差Δ2が“0”等か否かで列車在線状態を判別する。また、入出差Δ1=[Bi+Ci−Bo−Co]も演算し、入出差Δ1が“0”等か否かでも列車在線状態を判別する。さらに、切替部44も設けて、常態では入出差Δ1に基づく判定を行い、車軸検出子11の故障その他の非常時には通出差Δ2に基づく判定を行うようにする。【選択図】 図1
