Application Number: JP,2022-099882
Category (FI): B61L25/02@Z,G01P3/36@C
Stage: PROBLEM TO BE SOLVED: To provide a speed calculation device and a speed calculation method for more accurately measuring speed of a movable body in comparison to a case when a composition of this invention is not provided.SOLUTION: A speed calculation device includes: an overhead wiring position calculation unit 111 for acquiring a first position which is a position of an object with a rail 102 as a reference in a position separated from a sensing unit 108 by a first distance from measured result by the sensing unit 108 installed on a vehicle 101 moving on the rail 102 by measuring the distance from the object such as trolley wire 103 or catenary wire 104 and a second position which is the position of the object with the rail 102 as the reference in a position separated from the sensing unit 108 by a second distance; and an estimated speed determination unit 114 for calculating the speed of the vehicle 101 based on difference from the first distance to the second distance and difference in time where the first position and the second position match.SELECTED DRAWING: Figure 1 (Grant)
