Title:
PRESSURE DISTRIBUTION SENSOR SYSTEM, METHOD FOR MEASURING PRESSURE DISTRIBUTION, AND PROGRAM FOR MEASURING PRESSURE DISTRIBUTION
Document Type and Number:
Japanese Patent JP2015219203
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a pressure distribution sensor system which is capable of measuring more accurate temporal variation of a load pressure distribution by correcting calculation in the case that a load pressure is varied during a measurement time.SOLUTION: The pressure distribution sensor system includes: a sheet-like pressure distribution sensor which has a plurality of pressure detection regions for respectively detecting a pressure applied from a measurement object, continuously or at intervals of a unit time; creep characteristic approximation curve calculation means which stores first pressure distribution data in each measurement interval, which is detected by respective pressure-sensitive sensors of the pressure distribution sensor, into a measured pressure distribution data storage unit and calculates temporal variation of a load pressure on the pressure distribution sensor due to the measurement object continuously or at intervals of the unit time on the basis of output values corresponding to pressures included in the pressure distribution data and detected by the plurality of pressure detection regions respectively; means which corrects an approximation formula calculation start time for the pressure distribution data in order to increase the accuracy of an approximation curve; and means which calculates temporal variation of the load pressure due to the measurement object by an approximation formula and the pressure distribution data.
