Status detection method and apparatus for load cell

A method for detecting the status of a load cell in a plurality of load cells in a material tank system, the method comprising the steps of:

• collecting, by way of a collection unit, characteristic sensing data of the load cells;
• calculating, by way of a calculation unit, an anomaly in the collected characteristic sensing data, including by at least:
• converting a time domain signal of each piece of the characteristic sensing data to a frequency domain through Fast-Fourier-Transformation calculation;
• and
• determining an anomaly through an amplitude-frequency characteristic comparison in frequency domain;
• and
• acquiring and outputting, by way of a sending unit, a corresponding load cell information when the anomaly exists.
