The present invention discloses a weighing system and a weighing method 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 a neighborhood defined by four neighboring points in front, back, left, and right of the load cell and four points on the diagonal directions in a matrix. A weighing control module polls the plurality of load cells to determine whether there is failed load cell(s), and performs the following calculation: W. = f ( W 1 ,W 2 ,W 3 ,W 4 ,W 5 ,W 6 ,W 7 ), where f is a non-linear mapping; W 1 ··· W 8 represent the weighing outputs of load cells corresponding to the eight points in the local small neighborhood, respectively, so as to calculate the estimated weighing output of the failed load cell. Thus, wastes on time, resource, and humans are avoided that are caused by the situation that a load cell cannot be timely replaced when the load cell fails or during the weighing procedure. |
