Problems solved by technology

In addition, because the MCU not only needs to implement the Ethernet function, but also needs to control other functions of the vehicle, the data conversion of the Ethernet occupies a lot of resources of the MCU, resulting in increased memory costs, and the real-time performance of the software protocol stack is poor, which cannot meet the needs of railways. Real-time Requirements of Ethernet

Abstract

The invention discloses a railway real-time Ethernet TRDP gateway, comprising a UART interface, a main control module, an Ethernet hardcore protocol stack module and an Ethernet bus interface, wherein the main control module is separately connected with the Ethernet hardcore protocol stack module and the UART interface; the Ethernet hardcore protocol stack module is connected with the Ethernet bus interface; and the Ethernet hardcore protocol stack module is used for implementing data transmission between vehicle-mounted equipment and train communication networks according to TCP / IP. By adopting the embodiment of the invention, the chip operates independently of the MCU through a hardware-based TCP / IP protocol stack, the network structure of the MCU can be optimized, and the requirements of railway Ethernet for real-time performance can be met.

Description

technical field [0001] The invention relates to the technical field of vehicles and railway trains, in particular to a railway real-time Ethernet TRDP gateway. Background technique [0002] In the past, the network technology for railways was only a few Mbit / s at the fastest. With the monitoring and recording of vehicles and equipment, the installation of communication functions such as wireless LAN for customers, the increase in the number of pixels of the monitoring camera in the car, and the increase in the size of the display in the car With the continuous strengthening of functions such as high-definition and high-definition image quality, the data transmission speed is no longer satisfactory. Therefore, as a data transmission technology that can achieve more than 10Mbit / s, Ethernet has become the expectation of everyone. The current international standard for real-time Ethernet train vehicle bus is IEC61375-2-3, and the new standard will be gradually applied to China's...
