Title:
TRAVEL DISTANCE MEASUREMENT SYSTEM, MEASUREMENT DEVICE, ARITHMETIC PROCESSING UNIT, TRAVEL DISTANCE MEASUREMENT PROGRAM, AND TRAVEL DISTANCE MEASUREMENT METHOD
Document Type and Number:
Japanese Patent JP2016095219
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a travel distance measurement system capable of improving accuracy by reducing errors of a travel distance.SOLUTION: A travel distance measurement system includes: distance measurement means 11 for outputting distance information for measuring the height of axles of wheels relative to a travel surface with which the wheels contact; rotating speed measurement means 21, 22 for outputting rotating speed information for measuring rotating speeds of the wheels; and arithmetic processing means 34 which calculates radiuses and outer peripheries of the wheels on the basis of the distance information and calculates the rotating speeds on the basis of the rotating speed information, so as to calculate a travel distance on the basis of the calculated outer peripheries and rotating speeds.SELECTED DRAWING: Figure 7
