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:(),where f is a non-linear mapping; andW. . . Wrepresents 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.

The present invention relates to a load cell topology network comprising at least one multi-branch cable and a plurality of load cells. Each multi-branch cable comprises at least three connectors and one or more groups of signal lines; each group of signal lines comprise at least three branch signal lines, with one end of each branch signal line connected to at least three connectors described respectively and correspondingly, and the other end of each branch signal line connected to a common node, thereby realizing the interconnection of the same kinds of electrical signals between respective connectors; each connector is adapted to be connected to another multi-branch cable or a load cell. The plurality of load cells are electrically connected by the multi-branch cable to form a topology network.
