This invention belongs to the field of sensor testing technology and discloses a method and system for testing the response time of a force-measuring digital sensor with dual redundancy verification. First, the output signals of the analog sensing unit and digital processing unit of the force-measuring digital sensor are acquired to obtain their response times. This overcomes the limitations of existing methods that rely on only one or two impact tests, enabling comprehensive capture of the response time of the sensor's core unit. Next, each functional component of the digital processing unit is tested separately to obtain the specific response time of each component, solving the problem that existing methods struggle to assess the variable delay within the digital processing unit and cannot grasp the delay distribution. Then, based on the time of each component, the internal decomposed time of the digital processing unit is obtained, forming dual-redundancy data with the overall response time of the digital processing unit. Finally, redundant errors are eliminated by taking the minimum value, and the result is superimposed with the response time of the analog sensing unit to complete dual-redundancy cross-verification, overcoming the deficiency of existing methods that lack internal cross-verification.
