1. A weighing method for providing a combined weighing value with a weighing system having uninterrupted weighing functions, the weighing system having a plurality of load cells, the weighing method comprising:

  • a) arranging the plurality of load cells so that each load cell has a local small neighborhood, the local small neighborhood being a neighborhood defined by four adjacent points in front, back, left, and right of the load cell and four points on the diagonal directions in a matrix, the local small neighborhood of each load cell having other load cells disposed on at least some points;

    b) determining, by a weighing control module of the weighing system, upon a start of a weighing operation, whether there is at least one load cell having no weighing output,when there is no load cell having no weighing output, then a combined weighing value of weighing system is determined according to the weighing outputs of all the load cells; and

    when there is at least one load cell having no weighing output, the at least one load cell being at least one failed load cell, then a calculation is performed by the weighing control module as follows for each of the at least one failed load cell;
