摘要

PROBLEM TO BE SOLVED: To provide a lifting means specification device, a lifting means specification method, a computer program, and a recording medium in which the computer program is recorded.SOLUTION: The present invention comprises: a map database for storing map data that includes position information pertaining to an entrance door; a probe information preservation unit for preserving probe information that includes ID information acquired from a mobile terminal device and capable of identifying the user of the mobile terminal device, positioning signal receive information indicating whether or not a position signal was received, position information, atmospheric pressure information and acceleration information; from a series of probe information provided with the same ID information and continuous in time, with a border position located near the entrance door that corresponds to a border between a first portion where the positioning signal receive information indicates having received and a second portion where the positioning signal receive information indicates having not received, probe information that corresponds to the second portion that satisfies a prescribed condition is extracted, and the lifting means located at the entrance door is specified on the basis of the atmospheric pressure information and acceleration information included in the extracted probe information.SELECTED DRAWING: Figure 1
