Document Type and Number:
WIPO Patent Application WO/2019/044616
Kind Code:
A1
Abstract:
Provided is a solenoid valve identification device that individually identifies each solenoid valve while suppressing increases in manufacturing costs. A solenoid valve identification device that is mounted to an industrial machine, including construction machinery and industrial vehicles to perform work by operating hydraulic actuators, wherein the solenoid valve identification device comprises: an inductance measurement circuit that causes an alternating current to flow to an electromagnetic valve solenoid in a hydraulic machine to cause pressurized oil to flow to the hydraulic actuators for actuation; an arithmetic logical unit that calculates the solenoid inductance on the basis of the alternating current flowing to the solenoid by way of the inductance measurement circuit; and a storage unit that stores the calculated solenoid inductance as individual identification information for the solenoid valve.
