中文摘要：

工程机械筑路机群系统是由多机种、高性能机械联合作业施工构成的复杂系统。筑路质量受多种因素影响，且难以在线监测和预测。选择影响筑路质量的关键因素，提出一种基于时间序列的信息融合方法，对筑路质量进行在线学习和预测。仿真试验表明了这一方法的有效性。

英文摘要：

The road construction machinery group of engineering machinery is composed of complex system by the combined operative construction of multi kind and high performance machineries. The quality of road construction is affected by various factors and is difficult to be supervised and predicted on line, By selecting the key factor that affects the quality of road construction, a kind of information mergence method based on time sequence has been put forward for carrying out the on line study and prediction of road construction quality, The effectiveness of this method was indicated by simulative test.
