Wind driven generator bearing wireless temperature measuring device capable of early warning in advance

The invention discloses a wind driven generator bearing wireless temperature measuring device capable of early warning in advance, and the device comprises a wind driven generator assembly which comprises a unit housing, a generator body, an end cover, a bearing body, and a sealing ring. And the temperature measuring and early warning mechanism comprises a bearing outer cover, a temperature sensor and a sleeve. One side of the bearing body is sealed through the bearing outer cover and the sealing ring, then heat of the bearing body is absorbed through grease in the bearing outer cover, then temperature data of the grease is detected through the temperature sensor, the temperature of the bearing body is judged according to the temperature of the grease, the temperature measurement accuracy is improved, and the temperature measurement efficiency is improved. And then timing operation is performed through the timer, and then the change trend of the temperature is calculated through the PLC in combination with da
