METHOD AND SYSTEM TO QUICKLY DETERMINE A WEIGHT

A method for determining the weight of an entity/item to be weighed on a weighing device (1), the weighing device comprising at least a weight sensor and a control unit (4),

the method comprising the following steps:
/a/ collecting weight raw samples (WSi) of the total weight sensed at the weight sensor(s), at a sampling frequency (F0), and converting each of the weight raw samples (WSi) into digitalized weight raw samples (DSi),
/b/ entering sequentially each of the digitalized weight raw samples (DSi) into a Butterworth filter, the latter issuing filtered weight samples (FSi),
/c/ defining a rolling window (RW) containing a parametrized number NS of latest filtered weight samples (FSi),
/d1/ determining, in the rolling window, the minimum (MIN) and maximum (MAX) values of filtered weight samples,
/d2/ comparing the value of MAX−MIN with regard to a parametrized Threshold (T),
/e/ if MAX−MIN is greater than Threshold (T), repeat steps/a/ to /d2/, and as soon as MAX−MIN is less than Threshold (T), output a final weight value (DV), obtained from one or more of the most recent filtered weight samples.
