<p>A method relating to stable state processing during digital measurement or remote measurement of a physical quantity, comprising the steps of: S1, sampling or remotely measuring n number of system physical quantities [y1, y2,... yn]T=Y to obtain a data sequence (I); S2, for the data sequence {yik}={yi(k-m)... yi(k-1)yik}, i∈[1, n], judging whether a current data value yik is in a transient state or in a stable state; S3, if the current data value yik is judged to be in a transient state, calculating a forced component as a stable state value according to the {Yk}; and S4, if the current data value yik is judged to be in a stable state, calculating an average value as the stable state value according to the {Yk}, or utilizing a digital low-pass filter to filter out random interference so as to obtain a stable state value. Also provided is a system relating to stable state processing during digital measurement or remote measurement of a physical quantity. The present invention solves the problem of stable state processing during the whole measurement process of a physical quantity, has a more accurate measurement result, and can faithfully and clearly reflect the time-dependent situation of the physical quantity.</p> |
