PURPOSE: To provide a system for detecting a position of a movable body capable of reducing installation and maintenance costs and reducing power consumption.CONSTITUTION: The present invention comprises: a plurality of receivers installed along a travel path of a railway vehicle; an information processing device; a vibration generator, an energy storage unit and an information processing device installed in the railway vehicle. The vibration generator generates electricity from vibrations during travel of the railway vehicle, and the energy storage unit is charged by voltage generated by the vibration generator each time the vibration generator generates electricity. When the power stored in the energy storage unit reaches a predetermined amount, a transmitter is made ready for operation by the voltage generated by the energy storage unit and transmits an identification number wirelessly. The information processing device counts the number of times the identification number is received, determines a travel distance travelled by the railway vehicle on the travel path on the basis of the number of times the identification number is received, and determines a position of the railway vehicle on the travel path from this travel distance.SELECTED DRAWING: Figure 1

    【目的】設置費用及びメンテナンス費用を抑え且つ消費電力の低減を図ることが可能な移動体位置検出システムを提供することを目的とする。【構成】本発明は、鉄道車両の走行経路に沿って設置された複数の受信器と、情報処理装置と、鉄道車両に設置されている振動発電機、蓄電部及び情報処理装置と、を有する。振動発電機は、鉄道車両の走行中の振動によって発電し、蓄電部は、振動発電機が発電する度にその発電した電圧によって充電される。送信器は、蓄電部に蓄積された電力が所定量に到達したときにこの蓄電部で生成された電圧によって動作可能な状態となり、識別番号を無線送信する。情報処理装置は、識別番号を受信した受信回数を計数し、受信回数に基づき鉄道車両が走行経路を走行した走行距離を求め、この走行距離から鉄道車両の走行経路上の位置を求める。【選択図】図1
