Abstract


Rolling bearing is a mechanical piece of equipment , with the rapid development of modern industry , the quality of detection by more and more attention . Currently, there are a lot of bearing fault diagnosis method , such as by the human ear bearing vibration sound to determine the fault, the degree of automation of this method is not high ; also be diagnosed by a signal processing method , but typically such systems are based on the PC is realized . We proposed an embedded ball bearing fault diagnosis system , relative to the PC diagnostic system run more stable and lower prices . The system consists of two parts of ARM and DSP , this paper describes the system design of the DSP-side , it mainly includes the following modules : front-end signal acquisition modules , DSP signal processing module and the backend HPI communication module . The present article describes the implementation of the system hardware circuit design and software framework . The paper first describes the bearing fault diagnosis system requirements analysis, system overall framework , the choice of the device for its realization of the program . Then describes the hardware and software design of the front-end signal acquisition module , and then focuses on the TMS320C6713 chip resources and external circuit design , including memory expansion , HPI circuit , clock circuit and power supply design and code . The design part of the system software framework , including the introduction and use of the DSP / BIOS operating system , task scheduling , HPI communication protocols to develop and program optimization method , given a process improvement method , this method helps the efficiency of the system further improved. Finally, a summary and outlook of the two guide topics . After the actual test , the design of the DSP side of the system to be completed within the specified time all diagnostic algorithm and stable system operation and control of the end of normal communication .
