<p>PROBLEM TO BE SOLVED: To solve the problem that complicated statistical processing is needed to detect a stick slip phenomenon and hardly performed by a CPU with low processing capability used for field equipment or takes too long time to actualize. SOLUTION: The quantity of a signal of a valve opening extent, etc., which is proportional to a speed or acceleration is found and this signal is compared with a reference signal of a set point of a valve to diagnose the operation of equipment. The complicated statistical processing becomes unnecessary and even the CPU with low processing capability can take the diagnosis at a high speed.</p> |
