Problems solved by technology

[0003] The existing train network control system usually collects all communication data into one communication trunk line for data transmission. When a large amount of communication data is transmitted at the same time, it is easy to cause communication data to be blocked, causing packet loss, etc. situation, thereby reducing the safety and reliability of the system

Embodiment Construction

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0023] The embodiment of the present invention discloses a train network control system based on TCN (TCN, namely Train Communication Network, train communication network), see figure 1 As shown, the train network control system includes a first CCU control unit 11 (CCU, i.e. Central Control Unit, central control unit), WTB train bus 12 (WTB, i.e. Wire TrainBus, twisted wire train bus) and MVB vehicle bus 13 (MVB, namely Multifunction Vehicle Bus, multifunctio...

Abstract

The present application discloses a TCN-based train network control system, which includes: a first CCU control unit, a WTB train bus and an MVB vehicle bus; the MVB vehicle bus includes a first-level MVB bus and a second-level MVB bus that are independent of each other ; Wherein, the WTB train bus communicates with the first CCU control unit through the gateway; the first CCU control unit communicates with the first-class control subsystem of the train through the first-level MVB bus, and communicates with the first-class control subsystem through the second-level MVB bus. The second type of control subsystem is connected by communication; the first type of control subsystem is a control system whose demand value for communication bandwidth on the train is greater than the preset value, and the second type of control subsystem is that the demand value for communication bandwidth is less than or equal to the preset value value control system. It can be seen that the present application reduces the probability of data blocking, that is, avoids the occurrence of data blocking as much as possible, and improves the security and reliability of the system.

Description

technical field [0001] The invention relates to the technical field of train communication, in particular to a TCN-based train network control system. Background technique [0002] The train network control system is the control and management hub of the train, which is mainly responsible for the output and status monitoring of all control commands. Whether the structure of the train network control system is reasonable or not will directly affect the safety factor and reliability of the train operation. [0003] The existing train network control system usually collects all communication data into one communication trunk line for data transmission. When a large amount of communication data is transmitted at the same time, it is easy to cause communication data to be blocked, causing packet loss, etc. situation, thereby reducing the security and reliability of the system. [0004] From the above, it can be seen that how to avoid the occurrence of data blocking as much as p...
