Because most wind fields are in remote zones, the temperature difference between day and night is large, the wind fields are influenced by environmental factors, the viscosity of lubricating oil is increased when the temperature is lower in winter, the lubricating part of a gear box can not be fully lubricated easily, and the phenomena of pitting, gluing and abrasion of a meshing surface, a bearing rolling body and a seat ring can be caused after long-term operation; when the temperature is too high in summer, if the heat dissipation of the gear box is poor, the temperature of oil products in the gear box rises quickly, according to the principle of a thermal equilibrium state, a thermodynamic system tends to be in thermal equilibrium after a long time under the condition of no external influence, and the viscosity of lubricating oil is reduced, so that an oil film on a meshing tooth surface is not formed, the tooth surface is easy to generate pitting and gluing phenomena, and the gear box of the wind generating set is easy to damage due to the reasons, and the service life is relatively short. In addition to the influence of the oil temperature, the cleanliness of the oil is also an important index influencing the gearbox. Therefore, various parameters of the lubricating oil need to be monitored and maintained later, so that the gear box can work in a proper working environment, and the service life of the gear box is prolonged. The existing monitoring mode is manual inspection, time is consumed, and the working strength is high. Also monitor through setting up the sensor, at the lubricating oil circulation flow in-process, monitoring data is undulant easily, produces the error, in addition, still because the geographical environment of wind field department does not generally have the network signal or the signal is not good, can't spread monitoring data fast, also brings inconvenience for later maintenance.
