Abstract：The on-line equipment fault diagnosis system is not suitable for fault detection and diagnosis of small and medium-sized equipment, because of its high cost and its inconvenience of installation and maintenance. This article designs a kind of intelligent rolling bearing real-time fault diagnosis system, which is based on TMS320C6713 to meet real-time diagnosis, intelligent diagnosis, portable equipment and other aspects of requirements. This article describes the design principles and methods of the system hardware and software in detail, realizes the application of the demodulated resonance technique based on hardware. The results show that the system can be conveniently applied to the project.
