Description

Technical Field

[0001] The present invention relates to the technical field of rail vehicle control, and in particular to a train network system, a train, and a train operation control method. Background Art

[0002] The Train Control and Management System (TCMS), usually also known as the network control system, i.e., the train network system, is used to realize the information transmission and sharing of each subsystem in the train, coordinate the control, monitoring, and diagnosis tasks of the relevant control systems and each subsystem, summarize the working states and fault diagnosis information of each subsystem, provide an information display and a human-machine interaction interface, and complete the control, fault diagnosis, status monitoring, etc. at the vehicle level. The train network system is mainly a communication network based on WTB (Wired Train Bus) and MVB (Multifunction Vehicle Bus) and / or based on ETB (Train Backbone Network) and ECN (Ethernet Configuration Network).

[0003] However, in the existing train network system, its related control network and detection network are often separately set up, resulting in too many types and quantities of interfaces to be deployed and configured in the network and the need to set many different network communication standards. As a result, the difficulty and workload of using the train network system for related operation work (such as monitoring, controlling, adjusting the train operation, and train networking, etc.) and maintaining the train network system such as development, debugging, and operation and maintenance are relatively high, and thus it is very inconvenient to use and maintain the train network system.

[0004] Moreover, in the existing train network system, due to the high degree of architecture redundancy, the number of transmission hops that the train-related information passes through during transmission is too many, so that the transmission speed of the train information is slower, which is not conducive to improving the timeliness of the response of the overall train network system-related work.

[0005] In addition, in the existing train network system, the networks of different carriages are often separately set up and the degree of their mutual connection and interaction is relatively low. For example, the train trailer, the train power car, and the train control car each have corresponding networks and the degree of their mutual association is relatively low, resulting in a relatively low degree of integration of the train network, which is not conducive to the flexible monitoring and control at the overall train level.

[0006] In summary, there are problems in the prior art that the convenience of using and maintaining the train network system is relatively low, the transmission speed of the train information is slower, and the degree of integration of the train network is relatively low, which is not conducive to improving the work efficiency of the work related to the train network system.

Therefore, it can significantly reduce the number of transmission hops required for relevant information transmission, enhance the response timeliness of the overall train network system-related work, and facilitate flexible monitoring and control at the overall train level. Moreover, due to the high degree of network integration, low redundancy, and concentrated functions, it can significantly improve the efficiency and convenience of using the train network for relevant operation work and maintaining the train network system.
