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

Abstract

The invention discloses a train network control system based on a TCN (Train Communication Network). The system comprises a first CCU (Central Control Unit), a WTB (Wire Train Bus) and an MVB (Multifunction Vehicle Bus), wherein the MVB comprises a first-grade MVB and a second-grade MVB which are independent of each other; the WTB is in communication connection with the first CCU through a gateway; the first CCU is in communication connection with a first-class control sub-system of a train through the first-grade MVB, and in communication connection with a second-class control sub-system through the second-grade MVB; the first-class control sub-system is a control system of which a required value of a communication bandwidth is greater than a preset value on the train; and the second-class control sub-system is a control system of which a required value of the communication bandwidth is smaller than or equal to the preset value. Through adoption of the train network control system, the probability of data jamming is lowered; the occurrence of a data jamming phenomenon is avoided as much as possible; and the security and reliability of the system are enhanced.

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...
