| 摘 要： | 针对多通道模拟信号的远程监测需求，设计一种基于以太网的远程双通道信号采集传输装置。基于FPGA
和高速AD 设计双通道模拟信号采集模块，通过FPGA 片上双RAM 模块的乒乓操作实现两路数字信号的高速缓存与
发送，基于UDP 传输协议和千兆网络芯片RTL8211DG 实现数字信号的远程传输，远程接收端根据接收到的UDP
包Mac 地址的不同分别缓存至不同的RAM 块。结果表明：该设计能实现两路信号的复现，具有较强的通用性、移
植性和拓展性。

Remote Dual Channel Signal Acquisition and
Transmission Device Based on Ethernet |
| |
| Abstract: | Aiming at the requirement of remote monitoring of multi-channel analog signal, a remote dual channel signal
acquisition and transmission device based on Ethernet is designed. The dual channel analog signal acquisition module is
designed based on FPGA and high-speed AD. The pingpong operation of dual RAM modules on FPGA chip is used to
realize the cache and transmission of two-way digital signals. The remote transmission of digital signals is realized based
on UDP transmission protocol and Gigabit network chip RTL8211DG. The remote receiver caches different RAM blocks
according to the Mac address of UDP packets received. The results show that the design can realize the reproduction of two
signals, and has strong versatility, portability and expansibility. |
