Description

Operation and maintenance method and device for autonomous CTC system

technical field

The invention relates to the technical field of maintenance of a railway dispatching command system, in particular to an operation and maintenance method and device for an autonomous CTC system.

Background technique

TDCS/CTC system has become the core system of railway dispatching and commanding. The key equipment of CTC system includes application server, database server, autonomous machine/integrated processor and network equipment, etc. The structure of CTC system is shown in Figure 1, including server, operating system , databases, network devices, and middleware. At the hardware equipment and operating system level, except for the self-regulatory machine/integrated processor which adopts special equipment, the application server and communication server are all commercial COTS equipment, and most of them use the Windows operating system; most of the database servers use foreign imported Most of the equipment and operating systems used in minicomputers and commercial database systems are provided by foreign manufacturers. Therefore, the development of CTC systems and the construction of Chinese railways are largely constrained by foreign technologies. The CTC operation and maintenance method refers to online monitoring and operation and maintenance management of general servers, terminals, Windows/Linux operating systems, network devices, and databases that carry CTC system services. The current CTC operation and maintenance has the following difficulties: (1) The foreign server commercial hardware equipment has frequent equipment model changes, and the spare parts cost and maintenance difficulty of the operation and maintenance unit are relatively high; (2) The current network of the CTC system all uses 0racle database and IBM storage equipment , but the overall price is high, product updates and upgrades are fast, and operation and maintenance costs continue to increase; (3) The CTC system uses a large number of Windows operating systems, and the risk of being vulnerable to network attacks or virus intrusion is still very high, and the loss of information leakage incidents is incalculable. .

The CTC system is a key information infrastructure and a four-level protection system, which has high requirements for the network security and information security provided by the railway dispatching command system. However, from the above existing application background, it can be seen that many core technologies of the CTC system Subject to foreign countries. At the national level, the core technologies of many domestic industries and systems also exist in the same problem as the CTC system. In order to solve this problem, my country has clarified the "Digital China" construction strategy and proposed a "2+8" security and controllable system. The transportation sector is one of the industries related to the national economy and people's livelihood, which requires independent product substitution in terms of basic hardware, basic software, and industrial application software, so as to truly achieve independent control. At present, the CTC system has begun to replace the application of independent products, carried out on-site pilots, and gradually applied on-site.

With the gradual application and popularization of autonomous CTC, autonomous software and hardware maintenance has put forward higher requirements for railway electrical personnel. How to accurately and efficiently help electrical maintenance personnel to grasp the status of equipment, deal with and solve fault problems in a timely manner , becomes particularly important. However, the existing CTC operation and maintenance methods and systems are oriented to general-purpose equipment, and there is no operation and maintenance method for the self-developed system, and the current operation and maintenance method is mainly based on manual inspection, repair and maintenance. Relying on equipment condition monitoring and manual maintenance for periodic planned maintenance, preventive maintenance cannot be achieved, and the real-time performance of CTC system operation and maintenance is poor. Some CTC operation and maintenance methods also introduce real-time monitoring methods and technologies. However, due to the technical limitations of general equipment manufacturers, real-time monitoring methods and technologies can only use network communication protocols such as SNMP and IMM. In the autonomous CTC environment, the operating system version is different from the existing ones, and the components included are also different, and the general SNMP service or IMM module cannot meet the operation and maintenance requirements under the Xinchuang platform. In addition, the critical information infrastructure protection regulations and the basic requirements of level protection 2.0 clearly put forward the requirements for safe operation and maintenance. As a critical information infrastructure and a four-level security system, CTC, under autonomy, includes servers, hardware, switches and operating systems. The application of autonomous components such as middleware and middleware also has information security design and application, involving terminal security (such as virus, malicious code) and border security (illegal intrusion, illegal outreach) and other related information security operation and maintenance Information, but also needs a new maintenance method to support.
