<p><P>PROBLEM TO BE SOLVED: To provide a position detecting device of a railway vehicle that can accurately detect in which branch line the railway vehicle has entered even when the spacing of the branch line narrows like the station yard and accuracy of a GPS measuring apparatus is low. <P>SOLUTION: The position detecting device includes: a distance calculating part 21 that calculates the moved distance while inputting an outline position of the vehicle H found by a GPS measuring apparatus 33; a traveling direction estimating part 23 that estimates a traveling direction by fuzzy inference by inputting an angular velocityωand an angular accelerationω' of the vehicle H obtained by a data obtaining part 22; a branch point estimation part 25 that estimates a branch point by inputting a moved distance from a distance calculating part 21 and the outline position from the GPS measuring apparatus 33 and inputting the traveling direction from the traveling direction estimating part 23; a branch track number detection part 26 that detects the branch track number where the vehicle H is traveling by the neural network method by inputting this estimated branch point, the angular velocity and speeds of the vehicle H; and a branch point collation part 27 that inputs the detected branch track number and the estimated branching point, and collates whether they agree to the line information prepared beforehand. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
