Abstract

The invention discloses an ECN board card, which comprises a network interface module for communicating with an external device, a data processing module for communicating with the network interface module through a MAC interface, and a storage module for communicating with the data processing module, wherein the network interface module is used for implementing interconversion between an Ethernetwaveform and an RMII network level signal; the data processing module is used for calling a TRDP protocol stack, analyzing a first MAC data packet into a TRDP frame, analyzing the TRDP frame into first data, and sending the first data to an upper computer; or packaging the second data received from the upper computer into a second TRDP frame, combining the second TRDP frame into a second MAC datapacket and sending the second MAC data packet through the MAC interface. It can be seen that in the invention, the simulation test of the application function of the ECN bus is implemented by means of the ECN board card interacting with the external device and the upper computer.

Description

technical field [0001] The invention relates to the technical field of simulation testing, in particular to an ECN board. Background technique [0002] ECN (Ethernet Consist Network, train real-time Ethernet bus) is the latest form of train bus, and its performance indicators such as bandwidth, flexibility, and scalability are much higher than the existing TCN (Train Communication Network, train communication network) train bus. As a new bus form, there is an urgent demand for simulation test tools for ECN bus equipment networking and train control and management system (TCMS, Train Control and Management System) application functions in China. The blank state seriously hinders the process of popularization and promotion of ECN bus in the track field. Contents of the invention [0003] In order to solve the above-mentioned technical problems, an embodiment of the present invention provides an ECN board to solve the problems existing in the prior art, and the technical sol...
