摘要： A method and device are provided which allow easy and reliable prediction of abnormality of a solenoid valve 1 before failure by detecting operating times of the solenoid valve 1 and discriminating, from the operating times, whether the changeover operation thereof is normal or abnormal. To achieve this, the position of a spool 6 at a stroke end is detected by position detecting means 11 connected to the solenoid valve 1. The movement starting time from the time point when the driving signal for the solenoid valve 1 is turned on or turned off to the time point when the valve member begins to move from the stroke end, and the movement completion time therefrom to the time point when the spool 6 arrives at the stroke end, are measured in a signal processing circuit 12 from the detected position signal and a clock signal. The signal processing circuit 12 discriminates whether the changeover operation of the valve member is normal or abnormal by comparing these operating times with a plurality of standard values previously inputted in the signal processing circuit 12. A display signal is output in response to the discrimination result.

摘要： PURPOSE: To surely detect the abnormality of a solenoid valve before failure by judging whether the switching operation is normal or abnormal based on the operation time detected from the solenoid valve. CONSTITUTION: The position of the stroke end of a spool is detected by the detection means attached to a solenoid valve, and spool movement starting time until the spool starts its motion from the stroke end after the drive signal of the solenoid valve became ON or OFF, and spool movement finishing time until the spool reaches the stroke end are measured in a signal processing circuit 12 from the detected signal and clock signals for measurement, and whether the switching operation of the spool is normal or abnormal is judged by comparing their operation time T1-T4 with a plurality of reference values T1a-T4a and T1b-T4b which were input in the signal processing circuit 12 beforehand, and an indication signal is output according to the results of the judgment.
