| Abstract: | The method that the vibration signal measure system is combined with data analyzing.During of the design of the system of on-line inspecting on spray drier's spray tube fault, under the control of the main control, the vibration signal acquisition of spray tube is realized by sensors, PLC, computer and etc.The signal is analyzed by wavelet in advance at the same time. The fact testifies this system can complete the vibration signal acquisition and analyzes the signal under strong yawp. |
