A fault double-layer redundancy monitoring method, and a fault double-layer redundancy early-warning method and system. The fault double-layer redundancy monitoring method comprises: on the basis of sensor groups which are correspondingly grouped according to operation parameters and are on a hoisting device, obtaining sensor data of each operation parameter; in first-layer monitoring, on the basis of whether a relevant actual measured value in the sensor data satisfies a configured conversion relationship, determining whether the hoisting device is in a first faulty operating condition, wherein the conversion relationship comprises a geometric conversion relationship between operation parameters corresponding to the relevant actual measured value; and in second-layer monitoring, on the basis of whether an actual measured value, that corresponds to a moment, in the sensor data satisfies a moment balance relationship between operation parameters of the corresponding moment, determining whether the hoisting device is in a second faulty operating condition, wherein the hoisting device is not in the first faulty operating condition. The fault double-layer redundancy monitoring method, and the fault double-layer redundancy early-warning method and system can be used for device fault monitoring.
