Data collecting system

Abstract

The invention discloses a data collecting system which comprises an FPGA chip, an external clock module, a download configuration circuit and an A / D conversion module, wherein the external clock module, the download configuration circuit and the A / D conversion module are respectively connected with the FPGA chip in a coupling mode. An IIFPGA is adopted by the FPGA chip. An ADuC 824 is adopted by the A / D conversion module. A clock chip MPC 92432 is adopted by the external clock module. A serial configuration device series EPCS16 is adopted by the download configuration circuit. According to the data collecting system, a high-speed data collecting system based on the FPGA is achieved, an AD device is used for conducting analog-digital conversion on a signal, and an internal module is designed through the FPGA, so that logic control of an ADC and a data-caching function are achieved.

Description

technical field [0001] The invention relates to a data acquisition system, in particular to an FPGA-based data acquisition system. Background technique [0002] In various industries of industrial production and scientific and technological research, it is often necessary to collect various data, such as liquid level, temperature, pressure, frequency and other information collection. In some fields such as image processing, transient signal detection, and software radio, data acquisition technology with high speed, high precision, and high real-time performance is required. [0003] The task of the data acquisition system is to process the analog signal output by the acquisition sensor and convert it into a digital signal that the computer can recognize, and the computer performs corresponding calculation and processing to meet different needs and obtain the required data. The quality of data acquisition system performance is determined by its accuracy and speed. On the pr...
