基于FPGA的光电数据采集和处理采集系统设计

Abstract

With the FPGA to acquisition and processing of optoelectronic data, through as the photoelectric conversion signals to do the analog to digital conversion, we can get numerical digital signals which can be processed, use of FPGA to the programmable of I2C protocol, so that some logic devices with I2C protocol can be used, so that we can better understand the advantages of the integration of FPGA processing, the results obtained for the use of FPGA for data acquisition and processing has very important significance.

The main work of this paper is the use of Veilog language to program I2C protocol and through I2C protocol to control of other chips, and ultimately to realize collecting and processing the fiber temperature we needed and how to more accurately display the temperature value.

The results show that, FPGA with I2C protocol can make devices higher integration, higher processing speed, the advantage in portability can be well reflected.

The feature of this paper is using FPGA to control time precisely, so as to achieve very accurate control of I2C protocol to realize communication. Keywords: FPGA; I2C protocol; optical data conversion
