Railway TDCS (Train Operation Dispatching Command System)/CTC (Centralized Traffic Control) system based on virtualization technology, and application thereof

Abstract

The invention relates to a railway TDCS (Train Operation Dispatching Command System) / CTC (Centralized Traffic Control) system based on virtualization technology, and application thereof. The system comprises a physical layer L1, a virtualization layer L2, an application layer L3 and a management layer L4, wherein the physical layer L1 comprises server equipment, network equipment and related network equipment; the virtualization layer L2 is used for integrating the calculation resource and network and storage resource of the physical layer; the application layer L3 is directly operated on thephysical layer; and the management layer L4 is used for carrying out distribution according to needs by aiming at the requirements of a CTS / TDCS application, and carrying out dispatching and control by taking a virtual machine or container according to the operation situation of a CTC / TDCS upper layer application. Compared with the prior art, the system can reduce the requirement of the CTS / TDCS system for physical equipment under the same functional requirement, improve the use ratio of calculation resources and lower system cost.

Description

technical field [0001] The invention relates to a railway TDCS / CTC system and its application, in particular to a railway TDCS / CTC system based on virtualization technology and its application. Background technique [0002] CTC (Centralized Dispatching System) / TDCS (Train Dispatching Command System) is the core system of railway traffic command, and has been widely used in various railway bureaus and stations. The CTC / TDCS central system of the Railway Bureau is composed of production subsystem, emergency backup subsystem, maintenance subsystem, query subsystem and corresponding network subsystem, each subsystem includes server, terminal and network equipment. Each server selects the hardware configuration according to the established role or function. For example, the database server is responsible for the storage of historical data such as system operation diagrams and scheduling commands, and adopts a PowerPC-based minicomputer as required; the application server is resp...

AI Technical Summary

Problems solved by technology

[0005] 2) Server load is unbalanced, resulting in waste of resources

Some servers in the central system are only responsible for some simple interface information interaction, and server computing resources are wasted

[0006] 3) The flexibility and responsiveness of fault management are low

When a server in the system needs to be replaced due to failure or downtime, it needs to be manually dismantled and replaced

The replacement process requires backup and restoration of software data and related functional tests after replacement, so it takes a long time, and generally needs to be carried out in the skylight point

And if there is also a failure or downtime in another department of the server, the entire system will lose the functions related to the server, which may even affect the dispatching command.

[0007] 4) The realization of the disaster recovery plan is complex and inefficient

When a serious failure occurs in the system or a short-term unrecoverable failure affects dispatching and command, the disaster recovery system or emergency backup system needs to be activated. Under the current structure, the switching process from the production system to the disaster recovery system can only be done manually Switching, the switching time is long, and the skill requirements for the personnel who perform the switching are also high

[0008] 5) The cost of maintaining the system is high

For the daily maintenance and monitoring of servers and network equipment in the system, it is generally necessary to set up an independent operation and maintenance system by adding software and hardware on the basis of the current system to realize related functions, which also increases the system construction cost to a certain extent.
