中文摘要：

针对继电器的寿命预测问题，基于BP神经网络，提出了一种新的预测方法。该方法采用BP神经网络建立起用继电器触头的超程时间和吸合时间来预测继电器剩余寿命的数学模型。着重分析了建模过程中的关键点，并结合实例验证了该方法的有效性。

英文摘要：

Aimed at the problem of relay＇ s lifetime prediction, a new method based on the BP neural network was proposed. This method uses the BP neural network to build a mathematical model of super-path time and pick- up time of relay contact, which can be used to predict the remaining life of relay. The key points of the model- building were analyzed. Combining examples, the effectiveness of the method was proved.
