Title:
METHOD AND SYSTEM FOR SENSOR INFORMATION ERROR CORRECTION
Document Type and Number:
Japanese Patent JP2015158476
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To facilitate building of an algorithm for more accurately correcting temperature information errors of internal sensors of ICT devices.SOLUTION: A sensor information correction method involves steps of; acquiring sensor information from an external sensor installed near an air inlet port of an ICT device and an internal sensor in the ICT device; computing a first time period corresponding to the maximum of a value obtained by plugging internal sensor temperature information at a second point in time, which is the first period after a first point in time when internal sensor temperature information is acquired, and external sensor temperature information at the first point in time into a predefined cross-correlation function; computing difference between internal sensor temperature information at a third point in time, which is the computed first period after the first point in time, and external sensor temperature information at the first point in time; and determining parameters of a function for correcting the sensor information on the basis of the difference.
