An application instance of FPGA in the field of PHM

With the extensive application of new types of sensors, the rate of data acquisition and transmission are becoming a problem in Prognostic and Health Management(PHM). This paper presents an FPGA-based method for high speed data acquisition and transmission taking full advantage of the parallel processing capabilities and easy to modify and upgrade features of FPGA, to cope with the difficulties of high-speed data acquisition and transmission. This article focuses on the components,performance and characteristics of the FPGA-based fault prediction and diagnosis system. The system uses an FPGA chip as the core operational component to achieve fast transfer of large amounts of data by FIFO. The use of programmable FPGA hardware, makes the data acquisition system design flexible, while improving the reliability of the system. It is also important for achieving the real-time online monitoring of failure.
