Abstract

The application discloses a central control device of a network control system of high-speed power trains. The central control device is characterized in that CNCs (Consist Network Card) realize network connection among all card plates in the central control device by an Ethernet network interface and network connection between the central control device and other equipment in the network control system of the high-speed power trains; SPCs (System Process Card) connected with the CNCs are used for treating interactive data between the SPCs and the network control system of the high-speed power trains and processing interactive data between the SPCs and all the equipment controlled by the central control device; STCs (Safety-communication Transmit Card) connected with the CNCs are used for forwarding interactive data between the CNCs and a main controller; RSCs (Remote Serial-communication Card) and DXCs (Digital Cross-Connect Card) respectively connected with the SPCs are used for forwarding interactive data between the first SPC and all the equipment controlled by the central control device. According to the application, not only can all board cards have access to an Ethernet optical-fiber ring network of the network control system of the high-speed power trains, but also connection with multiple third-party equipment is realized, so that the addition of extra function plugins and expansion of the functions of the existing plugins can be well supported.

Description

technical field [0001] The invention relates to the field of train control, in particular to a central control device of a high-speed train network control system. Background technique [0002] As the nerve center and brain of the entire train control, the network control system plays a vital role in high-speed trains. [0003] In the prior art, it mainly includes a network control system based on the TCN network architecture and a network control system based on the ARCNET network architecture. Among them, the TCN network architecture is mainly based on the two-layer communication architecture of WTB+MVB, and the train bus adopts WTB, WTB transmission The speed is 1.0Mbit / s, and the vehicle bus adopts MVB with a transmission speed of 1.5Mbit / s; the ARCNET network architecture is based on ANSI 878.1, with a transmission speed of 2.5Mbit / s and a token ring access control method. [0004] The inventor found through research that with the rapid development of high-speed railwa...
