Design and implementation of Internet of Things environmental monitoring data transmission System based on FPGA

随着物联网行业的快速发展,环境监测系统的复杂度和集成度也逐渐提高,数据的传输量也迅速增长,传统的数据传输总线在一定程度上很难满足高数据传输的要求。基于FPGA设计实现了基于用户数据报传输协议(User Datagram Protocol, UDP)的千兆以太网传输系统。首先,详细阐述了UDP千兆以太网传输系统的现实方案,然后采用仿真软件对系统方案进行验证,最后,基于Xilinx的FPGA开发板对系统方案进行了具体的实现和功能性验证。实验结果表明:该系统中以太网传输逻辑正确,系统传输速度非常高,最高可达到910 Mbps,能满足绝大多数物联网数据采集系统的实际传输需求,具有良好的可移植性和实际的推广价值。

With the rapid development of the Internet of things and the increasing complexity and integration of environmental monitoring system, conventional data buses are difficult to meet the requirements of rapid data transmission. The purpose of this study is to design and implement a Gigabit Ethernet transmission system based on FPGA and user datagram protocol(UDP). Firstly, the practical scheme of UDP Gigabit Ethernet transmission system is described in detail. Then designed system function is verified by simulation software toolkit. Finally, the Gigabit Ethernet transmission system was implemented using XINLINX FPGA board and experimentally tested. The experimentally results show that the Ethernet data transfer logic is correct and the data transmission speed can reach 910 Mbps. The Ethernet transmission system can meet the actual transmission requirements of most Internet of things data acquisition system and has good portability and promotion value.
