Abstract: Provided in the present invention is a bearing maintenance timing acquisition method: first, acquiring vibration signals of a bearing under different loads; then, respectively acquiring dimensionless parameters according to the vibration signal of each load; thus, acquiring predicted damage condition distribution data of the bearing under different loads according to the dimensionless parameters; and finally, obtaining accurate maintenance timing based on the predicted damage condition distribution data under different loads, so as to prolong the service life of the bearing while reducing maintenance costs.

Abstract: Disclosed is a self-powered real-time monitoring system for fluid flushing of an underwater fixed foundation. Said system converts wave energy into electrical energy by means of a wind energy capturing module and a wave energy capturing module, and then uses the electrical energy to supply power to a settlement monitoring module, achieving the reduction of power consumption of the settling monitoring module during the detection of underwater surface settlement at the periphery of a fixed foundation.
