摘要
基于FPGA和单片机技术,设计了多路信号光纤传输系统,利用单片机实现了模拟数据的高精度采集和通信信号的双向传输,利用FPGA实现了多路复杂信号的处理与传输;实验证明:该系统不仅能传输多路模拟与数字信号,以及低速数字信号与高速脉冲信号,还能实现双向CAN通信;与现有光纤传输系统相比,多路信号光纤传输系统不仅实现了多路复杂信号的采集,而且使用一根光纤实现了大容量多数据的双向传输,一方面减小了产品体积,另一方面降低了产品成本。
Based on FPGA and MCU technology, a multi--channe] signal optical fiber transmission system is designed, which makes use of MCU for high--precision analog data acquisition and bidirectional transmission of a communication signal; FPGA for processing and trans- mission of multi--channel complex signals. Experiments show that： the system not only can transmit multi--channel analog and digital sig- nals, low--speed digital signal and high--speed pulse signal, but also can realize the bidirectional CAN comumnication. Compared with the existing optical fiber transmission system, the multi--channel signal optical fiber transmission system realizes data acquisition of multi--chan- nel complex signals, also realizes hi--directional transmission of multiple high--capacity data with a fiber. （In the one hand reduces the volume of the product, on the other hand to reduce the product cost.
