Dynami measuring method of linear, rotary and pendulum motions by employing a measuring system containing at least one incremental motion pickup and precise generator as well as measuring system for making the same

摘要

The invention relates to a method of dynamic measurement of linear, rotary, and swinging movements with a measuring system comprising at least one incremental movement sensor (4) and a precise pulse generator (3 &copy& ) in which the precise pulse generator (30) serves to measure the length of time pulses immediately following each other between the pulses of the incremental movement sensor (4) of the object under measurement. Prior to the measurement proper, the currently existing constants of each member of the measuring system, in particular the number of pulses of the incremental movement sensor (4) per revolution or unit path, the chosen range of measurement and the chosen range of the produced output signal, are used to determine the resulting conversion constants of the measuring system, whereupon follows the measurement proper during which the previously determined resulting constants of the measuring system and the length of the time intervals immediately following each other between the pulses of the incremental movement sensor (4) are used to determine the characteristics of the movement of the object under measurement, out of which characteristics an output signal is then created, thus obtaining a reliable and precise measurement of the movement of the object under measurement in each of the wide range of possible movements. The invention also relates to a measuring system for carrying out the method. IMAGE
