基于FPGA的高温数据采集系统设计

Design of high temperature data acquisition system based on FPGA

这是一个基于FPGA的高速耐高温数据采集系统,该系统采用FPGA作为控制器,采用Verilog语言控制时序,利用FPGA内部自带的RAM设计16位的FIFO,实现数据的缓冲存储,主要完成电平偏移、A/D转换控制、数据缓存FIFO三部分功能。系统所选器件都为耐高温低功耗芯片,适用于油田井下高温作业。仿真及实验测试结果显示,所设计的数据采集系统达到了预期的功能。

This is a high temperature data acquisition system based on FPGA.It contains three functions of level migration, A/D switching control, data caching FIFO.Using Venlog hardware description language controls timing sequence.A 16-bit FIFO is designed to realize the data buffering by using the internal RAM in FPGA.The device used in this system are high temperature resistance, low power consumption chip, suitable for downhole high temperature operation.The simulation and experimental results show that the designed data acquisition system has good fucdons.
