Problems solved by technology

The industrial communication environment is not yet unified, and most of the current methods are implemented by ASIC, ASSP and MCU, which is very inflexible. It is necessary to change the hardware and corresponding software stack for each protocol, or to develop multiple circuit boards to support; and As systems are upgraded, they will not be able to meet the needs of processing power, real-time and expansion

Abstract

The invention relates to an industrial Ethernet controller based on an FPGA (Field Programmable Gate Array), which adopts a modular design and specifically comprises an MRAM (Magnetic Random Access Memory) storage module, an SDRAM (Synchronous Dynamic Random Access Memory) storage module, a FLASH storage module, an Ethernet interface module, a current detection module, a voice module and an expansion interface module. A Cyclone IV series chip EP4CE115F29C7 launched by the Altera company is used as a core device and is respectively connected with each functional module through on-chip resources, so that each function of the industrial Ethernet controller is realized.

Description

technical field [0001] The invention relates to the field of rail vehicle communication networks, in particular to an FPGA-based industrial Ethernet controller, which implements a high-speed, reliable and stable data transmission system using an FPGA hardware platform. Background technique [0002] The train communication network has the characteristics of high real-time, and needs to transmit monitoring information, process information and massive multimedia information at the same time, which requires the communication network to have a high bandwidth. With the rapid development of train communication network technology, the traditional TCN network is difficult to meet the requirements of modern train real-time control and communication bandwidth due to its low speed. [0003] Due to its fast data transmission speed, high bandwidth, and stable performance, industrial Ethernet is widely used in vibration, high temperature, interference, and humid train communication network...
