摘要
针对高速列车上空气动力学试验布线复杂,易受干扰等问题,提出了分布式以太网检测系统,并设计了一个嵌入式以太网接口,采用ENC28J60作为以太网控制器和ARM Cortex-M3内核的STM32作为主控制器,移植了RT-Thread嵌入式系统以及LwIP协议栈,并建立了基于TCP的应用程序,实现了与上位机的高速以太网通信。经过测试,该以太网接口稳定可靠,满足高速列车空气动力学试验的要求。
A distributed ethernet detection system and an embedded ethernet interface are designed for the cabling complexity and EMI problem in high-speed aerodynamics experiment.STM32 with ARM Cortex-M3 core is adopted as the chief controller and ENC28J60 as the Ethernet controller:RT-Thread embedded system and LwIP protocol stack are transplanted in the chief controller,the application based on TCP is built and the high speed ethernet communication with the upper computer is realized.The ethernet interface which is stable and reliable met the requirments of high-speed aerodynamics experiment after test.
