Abstract

See full text

A weighing system and a weighing method are disclosed having uninterrupted weighing functions. A plurality of load cells in the weighing system are arranged so that each load cell has a local small neighborhood, the local small neighborhood being defined by four neighboring points in front, back, left, and right of the load cell and four points on diagonal directions in a matrix. A weighing control module polls the load cells to determine whether there is failed load cell(s), and performs a calculation:

description='In-line Formulae' end='lead'W.=f(W1,W2,W3,W4,W5,W6,W7),description='In-line Formulae' end='tail'

where f is a non-linear mapping; and

W1 . . . W8 represents weighing outputs of load cells corresponding to the eight points in the local small neighborhood so as to calculate an estimated weighing output of the failed load cell.
