Title: Measuring method of number of rotations
Inventor: KAWAOMO HIDENORI
IPC: G01P3/489
Filed: 1988-07-12
Abstract: PURPOSE:To conduct extremely precise measurement of the number of rotations at all times in a wide speed range from a low speed area to a high speed area by prolonging a sampling time until a count value of the number of pulses of a rotation pulse signal always becomes a prescribed value or above. CONSTITUTION:When a count value 2 of the number of pulses of a rotation pulse signal 1 covering a required sampling time does not reach a prescribed value set beforehand, the required sampling time is prolonged until the count value 2 exceeds a prescribed value. At the time point when the count value 2 exceeding the prescribed value is obtained, the same count value is divided by the prolonged sampling time and the number of rotations of a rotary body is computed. Since the sampling time is prolonged and the number of rotations of the rotary body is determined on the basis of the prolonged sampling time, according to this method, the number of rotations is measured with prescribed precision even in a low speed area wherein the time width of the rotation pulse signal is large.
