摘要
随着物联网时代的到来,物物相连已成为趋势,而大多数物联网终端设备采用的是RS-232/485/422通信协议。在现有基于TCP/IP的Internet网络基础上完成物联网信息的传输和交换,可以节约大量的人力、物力,而串口服务器是为各种串口电平(例如TTL、232、485和422等)到以太网网络之间完成数据转换的通信接口转换器。本设计基于Zynq FPGA研制了一种可连接PLC、集中器和串口传感器等的16路串口服务器。该设计以Xilinx的Zynq FPGA为硬件平台,实现了16路串口到网口的通信。
With the advent of the internet of things era,things are linked together has become a trend,then the most of the internet of things terminal equipments use RS-232/485/422 communication protocol.It completes the transmission and exchange of internet of things information on the basis of the existing Internet network based on TCP/IP,and can save a lot of manpower and material resources.However,the serial device server is a communication interface converter to complete the data conversion between various serial interface electrical level(for example TTL、232、485 and 422)and Ethernet network.Based on Zynq FPGA,a 16 channel serial device server is developed,which can connect PLC,concentrator and serial interface sensor.The design takes the Zynq FPGA of Xilinx as the hardware platform to realize the communication from 16 channel serial interface to network ports.
