Abstract
PURPOSE:To make it possible to discriminate the presence of chattering and to measure the switching time of a switching device accurately by providing a time measuring device to measure the pulse width of an output signal of a control signal detector in consideration of the presence of chattering. CONSTITUTION:By composing a control signal detector with a retriggerable multivibrator, for example, the output pulse width T' is output longer the time (t) between a chattering noise and an instruction. This pulse width T' is measured by a pulse width measuring device 9b, and the measurement data is delivered to an upper side CPU 9c. At the upper side CPU 9c, the measurement value and the time width T to determine the circuit constant of the control signal detector are compared to make it possible to discriminate the presence of a chattering. And when a chattering is generated, an accurate switching time T1 can be obtained in consideration of the error time (t) from the pulse times T and T' to the data from the switching measuring device 9a. In such a way, the discrimination of the presence of a chattering and the measurement of an accurate switching time in the upper side CPU 9c is made possible.
