The embodiment of the invention provides an early warning method and device applied to a power take-off system, and relates to the field of power take-off equipment. The early warning method applied to the power take-off system comprises the steps that when the power take-off system is in an operation state, the oil temperature of a power take-off device is obtained in real time; then, according to a pre-constructed power take-off system heat conduction physical model and the oil temperature of the power take-off device, the instantaneous temperature of a cross shaft is calculated, and according to a pre-constructed cross shaft oil throwing physical model and the instantaneous temperature of the cross shaft, the instantaneous oil throwing amount of the cross shaft is calculated; and then,according to the oil temperature of the power take-off device and the instantaneous oil throwing amount of the cross shaft, the power take-off system is monitored, early warning prompt information isobtained, when the power take-off system operates, the oil throwing amount of the cross shaft and the temperature of the power take-off device can be monitored in real time and early warned, faults are effectively avoided, and the cost of part replacement can be reduced.

    本申请实施例提供一种应用于取力系统的预警方法及装置,涉及取力设备领域,该应用于取力系统的预警方法包括:在取力系统处于运行状态时,先实时获取取力器油温;然后根据预先构建的取力系统热传导物理模型和取力器油温,计算十字轴瞬时温度,以及根据预先构建的十字轴甩油物理模型和十字轴瞬时温度,计算瞬间十字轴甩油量;进而根据取力器油温和瞬间十字轴甩油量对取力系统进行监控,得到预警提示信息,能够在取力系统运行时,对十字轴甩油量和取力器温度进行实时监控并预警,进而有效避免故障的发生,进而有利于降低更换部件的成本。
