摘要
针对海洋数据采集系统中串行数据传输能力不能满足海洋环境实时监测需求的现状,设计并实现了一种传输速率较高的以太网数据传输系统。系统以STM32F207VGT6处理器为核心,选择轻量级的LwIP作为以太网协议栈,将LwIP TCP/IP协议栈移植到STM32F207VGT6上,在应用层实现了一个网络、串口数据双向传输的数据传输系统。经测试,其传输速率优于同条件下RS232、RS485、CAN总线的传输速度,满足了设计要求。
Due to the status quo that serial data transmission capacity can not meet the demand of marine environment real-time detection in the marine data acquisition system, this paper designs and implements a faster Ethernet data transmission system, which mainly consists of STM32F207VGT6 processor and a lightweight LwIP as protocol stack. By means of transplanting LwIP pro- tocol stack into processer, it implements a two-way data transmission system between serial data and Ethernet data in application layer. The test shows that transfer rate with this method is superior to RS232 ,RS485, CAN bus in the same condition, which meets the design requirements.
