Problems solved by technology

In recent years, with the development of network technology and the improvement of network performance requirements in the field of industrial control, Ethernet is gradually entering the field of industrial control, forming a new type of Ethernet control technology, so the existing train communication network (Train Communication Network; Hereinafter referred to as: TCN) control system in which MVB and Ethernet co-exist has appeared in the communication mode, which requires the main control equipment of the train to be able to process both MVB data and Ethernet data, but the main control equipment in the existing train cannot It can handle both MVB data and Ethernet data, which cannot meet the requirements of the communication mode where MVB and Ethernet coexist in the TCN control system

Abstract

The invention provides a master control device and a data transmission method. The master control device comprises a Multifunction Vehicle Bus (MVB) printed circuit board, a central processing unit printed circuit board and an Ethernet printed circuit board, wherein the MVB printed circuit board is used for receiving first MVB data which are transmitted by a train communication network device, the central processing unit printed circuit board is connected to the MVB printed circuit board and is used for transmitting first MVB data to the Ethernet printed circuit board through an external device bus which is arranged between the central processing unit printed circuit board and the Ethernet printed circuit board, and the Ethernet printed circuit board is connected to the central processing unit printed circuit board and is used for converting first MVB data to isolated differential level signals and transmitting the isolated differential level signals to an Ethernet device. The master control device can process MVB data and Ethernet data and can meet the requirement of the simultaneous communication mode of the MVB and the Ethernet in a train communication network control system.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a master control device and a data transmission method. Background technique [0002] In recent years, with the rapid development of the railway industry, fieldbus has become more and more widely used due to its advantages of high reliability, low cost, and low failure rate. As the network communication standard of Chinese railway rail vehicles, the multifunctional vehicle bus ( Multifunction Vehicle Bus (hereinafter referred to as: MVB) is widely used in rail transit fields such as locomotives, bullet trains and subways. [0003] Ethernet has the advantages of high transmission speed, low energy consumption, convenient installation, good compatibility, high openness and many supporting devices. In recent years, with the development of network technology and the improvement of network performance requirements in the field of industrial control, Ethernet is gradually enterin...
