The invention discloses a method, system and device for predicting the residual life of a rolling bearing based on an informer model, and the method comprises the steps: S1, obtaining an original vibration signal of a bearing, and obtaining a multi-dimensional data set; s2, inputting the multi-dimensional data set into an informer model to obtain a prediction result; and S3, comparing the prediction result with a preset threshold value, if the prediction result is greater than the preset threshold value, calculating the remaining life of the rolling bearing, and if the prediction result is greater than the preset threshold value, returning to the step 1 to execute. According to the invention, effective and reliable service life prediction of the bearing can be realized. 本发明公开了一种基于informer模型的滚动轴承剩余寿命预测的方法、系统及装置，所述方法包括，S1、获取轴承的原始振动信号得到多维数据集；S2、将多维数据集输入informer模型中得到预测结果；S3、将预测结果与预设阈值做比较，若预测结果大于预设阈值，计算滚动轴承剩余寿命，若预测结果大于预设阈值，则返回步骤1执行。本发明可以实现对轴承有效可靠的寿命预测。
