A SYSTEM FOR MONITORING ABNORMALNESS OF A VALVE BY DETECTING OPERATION CURRENT OF A VALVE USED FOR CONTROLLING OIL PRESSURE

摘要

PURPOSE: A system for detecting the breakdown of a valve by detecting the operating current of the valve used for an oil pressure control is provided to accurately detect the actual operating current flowing in the valve used for an oil pressure control. CONSTITUTION: A system for detecting the breakdown of a valve comprises a power source(10), a current detector(11), a current amplifier(12), an operation unit(13) and an output unit(14). The power source supplies power. The current detector is connected to the valve used for an oil pressure control. The current detector detects the operating current flowing in the valve. The current amplifier amplifies an operating current signal. Using the operating current signal, the operation unit detects the breakdown and determines the reason for the breakdown. The output unit processes and outputs the information on the breakdown detection and the reason for the breakdown.
