Abstract
A load cell has four resistive strain gauges, a digital-to-analog conversion circuit and a signal processor. The signal processor can output a real-time load stress value Fn and a real-time state information matrix St. A weighing network is made of a load cell array composed of a plurality of the load cells, a collection device for collecting external information, and a control terminal. Further proposed in the present invention is a monitoring method for a weighing network, applied to the aforementioned weighing network, wherein the control terminal collects real-time external information, and a real-time load stress value Fn and a real-time state information matrix St for each load cell in real time; and compares the real-time external information, and the real-time load stress value Fn and the real-time state information matrix St for each load cell with data stored in a weighing process database to monitor the state of the weighing network.
