7. The high-sensitivity monitoring and pre-warning method for corrosion of the bearing caused by the thin liquid film according to claim 6, wherein in the step (2), after the early warning response signal is sent out, the method prompts that the relative humidity value of the exposed environment of the bearing is higher, and the possibility that a condensed liquid film is generated on the surface of the bearing due to the higher relative humidity of the environment exists; at this moment, the temperature and humidity of the environment where the bearing is located need to be regulated and controlled in time by related personnel, so that the relative humidity of the environment where the bearing is located is reduced to be below a threshold value.
8. The high-sensitivity monitoring and pre-alarming method for bearing corrosion caused by a thin liquid film according to claim 6, wherein in the step (3), when a condensed liquid film exists on the surface of the bearing due to high relative humidity of the environment, a real-time current signal caused by existence of the thin liquid film due to change of temperature and humidity of the environment is sensed and monitored by a thin liquid film monitoring probe; the condensed liquid film can communicate one end of the first electrode with one end of the second electrode; the other end of the first electrode and the other end of the second electrode are respectively connected to the current acquisition component through probe leads, and the current acquisition component detects galvanic couple current in a circuit formed by the first electrode, the condensate film and the second electrode and transmits the current to the secondary processor.
9. The high-sensitivity monitoring and pre-alarming method for corrosion of the bearing caused by the thin liquid film according to claim 6, wherein in the step (4), when the alarming part sends out an alarming response signal, the method indicates that the corrosion of the bearing caused by the condensation of the thin liquid film due to the change of the temperature and the humidity of the exposed environment occurs on the surface of the actual bearing, and the secondary processor predicts the corrosion change trend of the bearing in the actual storage and transportation environment according to the change of the current.
