A Device Performance Data Acquisition System Based on Data Fusion Method

Abstract

The data acquisition system is a system which collects the analog signal from the sensor, converts it into digital signal, then sends it to the computer for processing, and outputs the processing results in the form of demand. Based on the research of USB technology, this paper describes a data acquisition system based on data fusion technology, including hardware design, firmware design, device driver design and host application design. In the part of hardware design, this paper first describes the performance and characteristics of data acquisition chip, FPGA and USB2.0 interface chip, and then gives the specific hardware design scheme. In the part of firmware design, this paper first introduces the firmware architecture of FX2, and then introduces the firmware design of GPIF interface mode in detail. In the driver development part, this paper first introduces the WDM driver development model, and then completes the USB device driver design of the data acquisition system. Finally, the device performance data acquisition system based on data fusion method is completed with driver.
