1. improve the rotating shaft speed measuring system of response time, it is characterised in thatIncluding being equidistantly distributed the sensing element (2) being arranged on rotating shaft (1) periphery, the quantity of sensing element (2) is N number of, NFor the positive integer more than or equal to 2;

  • Also include the sensor (3) being obtained induced signal by sensitive element;

    Also include the signal processing apparatus (5) being calculated rotating speed by induced signal;

    Signal processing means processes process is as follows;

    Under axis of rotation state, induction apparatus senses each sensing element successively, often will produce one through a sensing elementIndividual induced signal, often obtains an induced signal and just obtains the moment point of an induced signal, according to the moment point of induced signalCalculate the time interval value of adjacent two pulse signals;

    When rotating shaft turns full first week, obtaining N number of time interval value, after suing for peace N number of time interval value, reciprocal process obtains againFirst rotating speed S1 of rotating shaft;

    After rotating shaft turns full first week, when often sensing a sensing element, it is thus achieved that new time interval value, according to first in first outNew time interval value is replaced corresponding original time interval value by data storage method, updates former N number of time interval value, after updatingThe summation of N number of time interval value after reciprocal again process the renewal rotating speed S11 obtaining rotating shaft.
