Abstract
The application discloses a strain sensor fault diagnosis classification method and system, and the method comprises the following steps: acquiring a voltage fluctuation curve corresponding to each strain sensor in a bridge state monitoring system; determining a strain sensor suspected to be faulty based on the voltage fluctuation curve corresponding to each strain sensor; comparing the voltage fluctuation curve of the strain sensor suspected to be faulty with the voltage fluctuation curve of a strain sensor adjacent to the strain sensor suspected to be faulty, and determining a strain sensor that is faulty; respectively encoding the strain sensor that is faulty and a normal strain sensor to obtain a binary coding result; and searching a fault coding table constructed in advance based on the binary coding result to determine the individual and quantity of the strain sensor that is faulty.
