Description
Technical Field
The invention relates to the technical field of maintenance of railway dispatching command systems, in particular to an operation maintenance method and device for an autonomous Central Traffic Control (CTC) system.
Background
The TDCS/CTC system has become a core system for railway dispatching and commanding, key devices of the CTC system include an application server, a database server, an autonomous machine/integrated processor, a network device, and the like, and the CTC system has a structure as shown in fig. 1, and includes a server, an operating system, a database, a network device, and middleware. On the level of hardware equipment and an operating system, except that the autonomous machine/the comprehensive processor adopts special equipment, an application server and a communication server are commercial COTS equipment, and most of the application server and the communication server adopt a Windows operating system; the database server mostly adopts a small-sized computer and a commercial database system introduced abroad, and most of equipment and operating systems used by the system are provided by foreign manufacturers, so that the development of the CTC system and the construction of China railways are greatly restricted by foreign technologies. The CTC operation and maintenance method is used for carrying out online monitoring and operation and maintenance management on a universal server, a terminal, a windows/Linux operating system, network equipment and a database which bear CTC system services. The current CTC operation and maintenance has the following difficulties: (1) the foreign server commercial hardware equipment has the defects of frequent equipment model change, higher spare part cost and higher maintenance difficulty of an operation and maintenance unit; (2) the existing network of the CTC system completely uses a 0racle database and IBM storage equipment, but the overall price is higher, the product is updated and upgraded faster, and the operation and maintenance cost is promoted continuously; (3) the CTC system uses a large amount of Windows operating systems, is easy to suffer from network attacks or high in virus invasion risk, and generates information leakage events and loss which is difficult to estimate.
The CTC system is a key information infrastructure and level protection four-level system, has high requirements on network security and information security given by a railway dispatching command system, but as can be seen from the prior application background, a plurality of core technologies of the CTC system are limited abroad. On the national level, a plurality of domestic industries and core technologies of the systems also exist in the same problem of a CTC system, in order to solve the problem, China defines the construction strategy of 'digital China', a '2 + 8' safety controllable system is provided, 8 industries related to the national civilization comprise the traffic field, and independent product substitution is required from the aspects of basic hardware, basic software, industry application software and the like, so that independent control is really realized. Currently, CTC systems have begun to be applied as a substitute for autonomous products, have been developed for on-site pilot trials, and have been gradually applied on-site.
With the gradual application and popularization of the autonomous CTC, the autonomous software and hardware maintenance puts higher requirements on railway electric service personnel, and it is very important how to accurately and efficiently help the electric service personnel to master the equipment state, timely handle and solve the problem of faults. However, the existing CTC operation and maintenance method and system are oriented to general-purpose equipment, and there is no operation and maintenance method for an autonomously developed system, and the existing operation and maintenance method mainly adopts manual regular detection, maintenance and maintenance, and only can carry out periodic planned maintenance by means of equipment state monitoring and manual maintenance, so that 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, but due to technical limitations of common device manufacturers, the real-time monitoring methods and technologies can only adopt network communication protocols such as SNMP, IMM and the like. In an autonomous CTC environment, the version of an operating system is different from that of the existing operating system, the included components are also different, and the general SNMP service or IMM module cannot meet the operation and maintenance requirements of a trusted platform. In addition, the requirements of security operation and maintenance are explicitly provided in the key information infrastructure protection regulations and the basic requirements of level protection 2.0, the CTC is used as a key information infrastructure and an equal level protection system, under the autonomy, the application of autonomy components such as a server, hardware, a switch, an operating system and middleware also has the design and application in the aspect of information security, and the CTC relates to relevant information security operation and maintenance information such as terminal security (such as viruses and malicious codes) and boundary security (such as illegal intrusion and illegal external connection), and a new maintenance method is further needed for supporting.
