| Abstract: | Combining with features of Wiener proof and Toeplitz equation,the paper deduced a simple solving method of multi-channel auto-regressive model,introduced method of analysis and synthesis of fire signals of belt conveyor with multi-channel. Matlab was adopted to simulate the fire signals and non-fire signals of belt conveyor.The simulation results showed that the synthestical signals had the same trends with original signals as a whole and had a feature of power spectrum matching. |
