Problems solved by technology

[0004] In the process of issuing a specific MVB network card, it includes two parts, hardware and software. The existing method is to develop software and hardware separately. And in the actual development process, the development of hardware often lags behind that of software, which will lead to the delay of software testing and modification, which will lead to the extension of the entire development cycle, thereby prolonging the development cycle

Embodiment 1

[0044] like figure 1 As shown, the MVB network card development method of the present embodiment includes:

[0045] Step S1: simulating the hardware logic structure of the MVB network card to be developed to form a virtual MVB network card;

[0046] Step S2: writing software into the virtual MVB network card;

[0047] Step S3: Run and verify the software on the virtual MVB network card.

[0048] The hardware logic structure of the simulated MVB network card to be developed in this embodiment includes at least a software installation board and a circuit structure other than the software installation board. The software installation board can generally be an ARM board, which is used to install ARM software, that is, the software described in this embodiment. The circuit structure other than the software installation board is usually FPGA—Field Programmable Gate Array programmable logic gate array.

[0049] The MVB network card development method described in this embodiment ...

Embodiment 2

[0071] The MVB network card development platform of this embodiment includes a hardware emulation sub-platform and a software loading and running sub-platform:

[0072] The hardware emulation sub-platform is used to emulate the logical structure of the hardware forming the MVB network card;

[0073] The software loading and running sub-platform is used to write software into the virtual MVB network card simulated by the hardware emulation sub-platform, and run and verify the software on the virtual MVB network card.

Abstract

The invention discloses an MVB network card development method and platform. The MVB network card development method and platform are designed in order to solve the problem that in the process of an existing MVB network card development method, a development period is long due to the fact that verification on software development can be carried out on the software development of an MVB network card only after hardware development is finished and a product is manufactured. The MVB network card development method comprises the steps of S1, simulating a hardware logical structure of the MVB network card to be developed to form a virtual MVB network card, S2, writing software into the virtual MVB network card, and S3, enabling the software to be operated and verified on the virtual MVB network card. According to the MVB network card development method and platform, analog simulation is carried out on hardware logic of the MVB network card through the software, then the software is verified on the virtual MVB network card, the software development period of the MVB network card can be greatly shortened, the development efficiency of the MVB network card is accordingly improved, and the MVB network card development method and the platform are easy, rapid and convenient to achieve.

Description

technical field [0001] The invention relates to the fields of computers and communications, in particular to a method and platform for developing an MVB network card. Background technique [0002] TCN (Train Communication Network, Train Communication Network) is a train and diagnostic information data communication network developed on top of the train distributed control system. MVB (MultifunctionVehicleBus, multifunctional vehicle bus) is a part of TCN, which is used to realize communication between devices located in the same vehicle or in different vehicles with fixed reconnection. TCN-MVB network technology complies with IEC61375-1 international standard. [0003] The MVB network card is used for the communication of the MVB network. The developed MVB network card should meet the technical requirements of MVB in the IEC61375-1 standard, and can realize the communication functions of process data, message data and monitoring data. For MVB type 1 equipment, it only has ...
