Multi-sensor Information Fusion Estimation Method of the Flow Speed of the Sewage Pipe

In order to solve the accuracy and delay problems in the traditional flow speed estimation method in the sewage pipe network system, we develop a kind of multi-sensor fusion estimation method. Autoregressive moving average model is used in the estimation process, 3 kinds of fusion method is compared. An example is presented to verify the algorithm, Matlab is used to caculate, and some pictures to explain our points.
