基于光纤传输的多路高速数据采集系统

介绍了8路高速数据采集传输系统的设计与实现。使用时分复用的数据传输方式将8通道数据通过3个光纤通道传输给处理设备,解决了多路高速数据传输的问题。采用FPGA作为主控芯片,TLK1501作为串/并转换和8 B/10 B编码芯片。A/D采样频率为20 MHz,整个系统的数据传输速率达到了1 920 Mb/s。通过使用Verilog语言编程,实现了数据的采集以及传输。该方案具有可行性好、方法简单、成本低的优点。

Multi-channel high-speed data acquisition system based on fiber optic transmission

In this paper,research the high speed data acquisition and transmission system of 8-channel.By using Time Devision multiplex,the data of 8 channels is transmit through 3 fiber tunnels.This design can solves the problem of high-speed data transmission of multichannel.Using FPGA as the master chip,TLK1501 as serial/parallel conversion and 8 B/10 B encoder chip.When sample rate of A/D is 20 MHz,the all data transmission rate of the system is 1 920 Mb/s.By using Verilog language programming,data collection and transmission functions is achieved.The scheme has a advantages of feasibility,simpleand and low-cost.
