Abstract
An equipment specifying system of the present invention includes: a flow path for supplying gas to a plurality of pieces of equipment; an ultrasonic propagation signal measuring section for measuring a propagation signal based on a time during which an ultrasonic wave propagates across the flow path; a signal pattern generation section for generating a signal pattern based on a change in a propagation signal; a signal pattern storage section for previously storing a plurality of signal patterns respectively corresponding to a plurality of pieces of equipment; a signal pattern comparison section for comparing a signal pattern generated by the signal pattern generation section with a plurality of signal patterns previously stored in the signal pattern storage section; and an equipment specifying section for specifying currently used equipment among a plurality of pieces of equipment, in accordance with the comparison results obtained by the signal pattern comparison section.
