The invention discloses a fault detection and verification device and a fault detection and verification method for an encoder in an elevator cage. The fault detection and verification device comprises a first encoder, a second encoder, a PLC, a fault alarm module, the elevator cage and an operation guide rail frame, wherein the first encoder and the second encoder are installed in the elevator cage; the shaft ends of the first encoder and the second encoder penetrate out of the elevator cage and are provided with driven gears; the two driven gears are connected with corresponding racks on theoperation guide rail frame in a meshed mode respectively; the first encoder and the second encoder are connected with a signal input end of the PLC by means of signal lines; and a signal output end of the PLC is connected with the fault alarm module. According to the fault detection and verification method, the pulse values of the two encoders are verified in real time, stable and reliable operation of the elevator cage is guaranteed, and the elevator cage is guaranteed to be able to stop precisely and safely.
