The Design of an Embeded Networked Machine tool’s Signal Acquisition and Analysis System （Beijing University of Technology）TAN,Yan-lei ZHANG,Hui-hui Abstract:To adapt the growing up of the manufacturing and provide the service of internet-monitor and malfunction-diagnoses for numerical control equipments, the information of numerical control equipments should be numbered and networked. The embeded networked machine tool signal acquisition and analysis system is just the platform for this purpose. The kernel processor of the system is ARM and DSP. The ARM’s main part is to realize the internet transportation and the task of DSP is to fulfil the high-speed data acquisition and high-density signal analysis. Practice proves that this system can efficiently complete the function of high-speed data acquisition、high-density signal analysis and real-time internet transportation, which can widely promote the application of the information and internet technology in the manufacturing.
