Abstract
PURPOSE: To perform highly accurate measurement in a short time without increasing the accuracy of the measuring instrument by adding an interrupt function to an arithmetic unit and a timer.
CONSTITUTION: A measuring instrument 1 and a timer 5 which permits setting of arbitraty time by an arithmetic unit 4 and has an interruption request function is connected to the arithmetic unit 4 which has an inerruption accept function. Then, the arithmetic unit 4 detects the change condition of the speed reference value of the drive system, and if there is any change, it calculates such measurement time at which a constant distance may be measured irrespective of that speed and se the timer 5 at the value correspoinding to that distance and speed and starts the timer. At the same time, it also resets and starts the measuring instrument 1. On the other hand, if there is interruption from the timer 5, an interruption processing program is execured, in which the distance is read out from the measuring instrument 1 and the reading-out of the speed corresponding to that distance is performed
