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.

Embodiment 1

[0093] Embodiment 1, add CTC / TDCS application in the new technology solution:

[0094] Such as Figure 4 As shown, expanding and adding new applications in the new technology solution includes the following steps:

[0095] Step 401 , evaluating the CPU, memory and storage requirements of the newly added CTC / TDCS application. The evaluation process takes into account factors such as the application's operating system requirements, workload, data volume, and storage space occupied by application logs. There should also be a margin, and the margin should be about 10% on the basis of the assessment;

[0096] Step 402, confirm the server and storage group where the newly added application is located, the confirmation process needs to be consistent with the basis of the physical equipment grouping for the importance of the newly added application or the CTC / TDCS operation command area to which it belongs;

[0097]Step 403, according to the application requirements and groups dete...

Embodiment 2

[0099] Example 2, virtual machine and container scheduling based on server load balancing:

[0100] Such as Figure 5 As shown, the scheduling of virtual machines and containers based on server load balancing includes the following steps:

[0101] Step 501, periodically monitor the running status of the physical server, including whether the server is online, the CPU and memory utilization of the server, and the monitoring period is 30 seconds to 5 minutes.

[0102] Step 502, determine whether there is or the server load is too high, when the server CPU utilization rate is greater than 80% for 3 consecutive monitoring cycles, or when the server memory utilization rate is greater than 90% for 3 consecutive monitoring cycles, it is judged that the server load is too high high;

[0103] Step 503, the judgment result is sent to the maintenance support module, and the maintenance support module sends an alarm to notify the maintenance personnel;

[0104] Step 504, judging whethe...

Embodiment 3

[0107] Example 3, server failure response:

[0108] Such as Image 6 As shown, the server failure response includes the following steps:

[0109] Step 601, periodically monitor the running status of the physical server, including whether the server is online, and the monitoring period is 30 seconds to 5 minutes.

[0110] Step 602, judging whether there is a server failure or not, when the physical layer monitoring module cannot obtain relevant status information about the operation of the server for more than 3 consecutive cycles, it is judged that the server is faulty, and the server is marked as offline, and the offline server will not Used by resource scheduling and control modules;

[0111] Step 603, the judgment result is sent to the maintenance support module, and the maintenance support module sends an alarm to notify the maintenance personnel;

[0112] Step 604, judging whether it is intra-group scheduling or out-group scheduling according to the load balancing sche...

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...
