Zusammenfassung:The invention discloses a method and a system for detecting an inertial instrument capable of automatically setting a threshold value in redundancy judgment. The method for detecting the inertial instrument capable of automatically setting the threshold value in redundancy judgment specifically comprises the following steps: judging pulse constant zero value output of the inertial instrument; if the inertia instrument detection result obtained through pulse constant zero value output judgment is normal, maximum value output judgment of the inertia instrument is carried out; if the inertial instrument detection result obtained through maximum value output judgment is normal, judging the consistency of the inertial instrument; and determining a fault recognition truth table according to the consistency judgment result, and obtaining an inertia instrument fault detection result. According to the method, fault detection and real-time online detection can be flexibly carried out in combination with the information
