针对当前旋转机组状态预测神经网络对新信息强调不足的问题，分析了原因，改进了ＢＰ网络模型，提出了新信息加权神经网络新型预测模型。提供了该预测模型的数学表达式和拓扑结构。取得了令人满意的在线预测的效果。
Aiming at the problem that the current state of the rotating machine is not enough to emphasize the new information, the reason is analyzed, the BP network model is improved and a new forecasting model of the new information weighted neural network is proposed. The mathematical expressions and topological structure of the prediction model are provided. Satisfactory online forecasting has been achieved.
