Description

Technical Field

[0001] The present invention relates to the field of railway communication signals, and in particular to a decentralized railway signal centralized monitoring system. Background Art

[0002] The CSM system is a special production system in the field of railway signals. It is a unified platform for centralized monitoring and data analysis of station signal equipment. It adopts a three-level three-layer structure, including the Railway Corporation, Railway Bureau (including the Electric Department), and Station. The station layer and CBI, TCC, power supply screen, ZPW2000, CTC and other system interfaces realize data collection, analysis and storage. Monitoring terminals are set up at the workshop, electric department, and railway bureau levels. Each terminal realizes the query and analysis of real-time data and historical data of each station under its jurisdiction through the application services provided by the monitoring bureau center.

[0003] The existing station node monitoring station of the centralized signal monitoring system is equipped with a single industrial computer and multiple field acquisition units to achieve real-time monitoring of the electrical characteristics of key nodes in the signal machinery room, data analysis and abnormal alarm, and transmit these collected data to the bureau monitoring center server in real time. The overall service life of the CSM system station equipment is 12 years, but the industrial computer equipment has a service life of 8 years. When the industrial computer in the monitoring station fails, since the station has no relevant redundancy measures, all real-time monitoring information of the station will stop under the current structure. Before the equipment at the station is repaired, the operation status of the signal equipment at the station is unknown and out of control.

[0004] If the above-mentioned industrial computer failure occurs, assuming it is a hard disk failure, it will cause the loss of related monitoring historical data and station engineering configuration data. During the recovery phase, data may need to be recovered from the manufacturer's SVN configuration library and the large database of the bureau monitoring center, which will take a very long time and cause a lot of failure delays.

[0005] In order to solve the above problems, people have been seeking an ideal technical solution. Summary of the invention

[0006] The purpose of the present invention is to address the deficiencies of the prior art and thus provide a decentralized railway signal centralized monitoring system with scientific design, high integration and good safety.

[0007] In order to achieve the above object, the technical solution adopted by the present invention is: a decentralized railway signal centralized monitoring system, comprising: The signal centralized monitoring bureau center has multiple monitoring application services and a cloud management platform built in; each monitoring application service is used to conduct network communication, data interaction and storage with the station-level monitoring station, and realize data flow scheduling and information routing functions; the cloud management platform is used to realize data backup between adjacent station-level monitoring stations, and when the station industrial computer of the station-level monitoring station fails, the application service of the failed station-level monitoring station is migrated to the station-level monitoring station of the adjacent station; The station-level monitoring station is connected to the signal centralized monitoring bureau center and is used to collect on-site data and upload it to the signal centralized monitoring bureau center, as well as to execute application business services. It is also used to store backup data of adjacent station-level monitoring stations and execute application business services of the adjacent station-level monitoring station after the application business of the adjacent station-level monitoring station is migrated to this station.

[0008] Furthermore, the cloud management platform is preset with a migration backup table and basic application business data packets of each station-level monitoring station machine. When a failure of the station industrial computer of the station-level monitoring station machine is detected, the target station-level monitoring station machine is determined according to the preset migration backup table, and a virtual machine command is sent to the target station-level monitoring station machine to control the target station-level monitoring station machine to open a virtual machine; at the same time, the cloud management platform searches for the basic application business data packet of the faulty station-level monitoring station machine, and sends the basic application business data packet of the faulty station-level monitoring station machine to the virtual machine of the station-level monitoring station machine at the adjacent station, so as to realize the installation of the basic application business data packet on the virtual machine, and update the application business based on the static configuration data increment and the dynamic historical data increment.

[0009] Furthermore, the migration backup table includes the station-level monitoring station machine ID of the current station and its redundant station-level monitoring station machine ID, wherein a preset direction is set for each line, and according to the preset direction, the station-level monitoring station machine of the station ahead of each station-level monitoring station machine is its associated redundant station-level monitoring station machine; For the terminal edge station, its associated redundant station-level monitoring station machine is the station-level monitoring station machine of the station behind it.

[0010] Furthermore, when the application services of the faulty station-level monitoring station are migrated to the station-level monitoring station at the adjacent station, the cloud management platform, after receiving the on-site data uploaded by the faulty station-level monitoring station, forwards the on-site data to the station-level monitoring station at the adjacent station for data backup and for the station-level monitoring station at the adjacent station to perform application services based on the on-site data.

[0011] Furthermore, when no failure occurs at each station-level monitoring station, the station-level monitoring station at the adjacent station can realize incremental mutual backup of static configuration data and historical dynamic data at preset time intervals.

[0012] Furthermore, when the fault of the station industrial computer of the faulty station level monitoring station is resolved, the cloud management platform will restore the static configuration data and historical dynamic data of the faulty station level monitoring station stored in the station level monitoring station of the adjacent station to the station industrial computer of the faulty station level monitoring station.

[0013] Compared with the prior art, the present invention has outstanding substantive features and significant progress. Specifically, the present invention proposes a decentralized railway signal centralized monitoring system, which utilizes the data backup and business migration functions of the adjacent station-level monitoring station machines to achieve that after the monitoring station machine fails and stops service, under the management and coordination of the bureau monitoring center cloud management platform, the adjacent station takes over the application business service functions of the station, thereby avoiding the failure and shutdown of the line station-level monitoring node; at the same time, when the faulty equipment is replaced, the monitoring station machine function of the station is restored in time, which greatly reduces the impact of the station node failure, improves the data security of the signal centralized monitoring system and the continuity and reliability of the business, and improves the disaster recovery and emergency response capabilities of the monitoring station nodes.

[0017] The technical solution of the present invention is further described in detail below through specific implementation methods.

[0018] Example 1 This embodiment provides a decentralized railway signal centralized monitoring system. Figure 1 As shown, including: The signal centralized monitoring center has multiple monitoring application services and cloud management platforms built in; Each monitoring application service is used to communicate with the station-level monitoring station and exchange and store data, and to implement data flow scheduling and information routing functions; The cloud management platform is used to realize data backup between adjacent station-level monitoring stations, and when the station industrial computer of the station-level monitoring station fails, the application business of the failed station-level monitoring station is migrated to the station-level monitoring station of the adjacent station; The station-level monitoring station is connected to the signal centralized monitoring bureau center and is used to collect on-site data and upload it to the signal centralized monitoring bureau center, as well as to execute application business services. It is also used to store backup data of adjacent station-level monitoring stations and execute application business services of the adjacent station-level monitoring station after the application business of the adjacent station-level monitoring station is migrated to this station.

[0019] In actual application, the signal centralized monitoring bureau center is generally set up in the computer room of the railway bureau, and the station-level monitoring stations are dispersedly set up on the line nodes as needed. Any two station-level monitoring stations, as well as the station-level monitoring stations and the bureau monitoring center are interconnected through the monitoring wide area network.

[0020] Specifically, Figure 2 As shown, the station-level monitoring station includes monitoring wide area network access equipment, station industrial control computers, communication interface machines, various collection machines, and various station subsystem interfaces; The collectors include an external power grid collector, a turnout collector, a track collector, a signal collector, a station-link collector, an insulation tester, a leakage tester, and a section collector.

[0021] The station subsystem interfaces include the station interlocking system CBI interface, the train control center system TCC interface, the ZPW200 track circuit system interface, the power panel system interface, the turnout gap system interface and the axle counting system interface, which are used for real-time monitoring and intelligent analysis of the operating status and key electrical parameters of these signal subsystems.

[0022] The communication interface machine is connected to the acquisition machine and the station subsystem interface respectively through the CAN communication interface or the RJ45 network interface, classifies and repackages the real-time collected information, and sends it to the station industrial computer through the RJ45 network interface; Specifically, each equipment acquisition machine is connected to the communication interface machine through CAN communication, each application system is connected to the communication interface machine through RJ45 network communication, the communication interface machine is connected to the monitoring industrial computer through RJ45 network communication, and the monitoring industrial computer is connected to the signal centralized monitoring bureau center through the monitoring wide area network access device.

[0023] Specifically, the station industrial computer is installed with an application program of the centralized signal monitoring system, which is used to realize functions such as data display, analysis, and alarm, and respond to relevant data request services of the bureau monitoring center.

[0024] Under normal circumstances, the station industrial computer at each station-level monitoring station performs the data forwarding, data display, analysis, alarm and storage functions of the station.

[0025] It should be noted that when no failure occurs at each station-level monitoring station, it will realize incremental mutual backup of static configuration data and historical dynamic data with the station-level monitoring station at the adjacent station at preset time intervals.

[0026] In particular, the station level monitoring station machine of the adjacent station refers to a redundant station level monitoring station machine of the current station.

[0027] Specifically, a preset direction is set for each line. According to the preset direction, the station-level monitoring station machine of the station in front of each station-level monitoring station machine is its associated redundant station-level monitoring station machine; for the terminal edge station, its associated redundant station-level monitoring station machine is the station-level monitoring station machine of the station behind it.

[0028] When the station industrial computer of the station-level monitoring station fails, the cloud management platform is preset with a migration backup table and basic application business data packets of each station-level monitoring station. When a failure of the station industrial computer of the station-level monitoring station is detected, the target station-level monitoring station is determined according to the preset migration backup table, and a virtual machine command is sent to the target station-level monitoring station to control the target station-level monitoring station to open a virtual machine. At the same time, the cloud management platform searches for the basic application business data packet of the faulty station-level monitoring station, and sends the basic application business data packet of the faulty station-level monitoring station to the virtual machine of the station-level monitoring station at the adjacent station, so as to realize the installation of the basic application business data packet on the virtual machine, and update the application business based on the static configuration data increment and the dynamic historical data increment.

[0029] Specifically, the migration backup table includes the station-level monitoring station machine ID of the current station and its redundant station-level monitoring station machine ID.

[0030] It can be understood that under the management of the cloud management platform, the wide area network, business data (real-time monitoring data of the station's collection machine and station subsystem interface), and application business services of the faulty station-level monitoring station are migrated to the station industrial control computer of the nearby station monitoring station, and the station industrial control computer of the nearby station monitoring station realizes the data display, analysis, alarm and storage functions of this station.

[0031] It can be understood that after the application business of the faulty station-level monitoring station machine is migrated to the station-level monitoring station machine at the adjacent station, the faulty station-level monitoring station machine only retains the data forwarding function, thereby collecting field data in real time and uploading the field data to the signal centralized monitoring bureau center. After receiving the field data uploaded by the faulty station-level monitoring station machine, the cloud management platform forwards the field data to the station-level monitoring station machine at the adjacent station for data backup and for the station-level monitoring station machine at the adjacent station to perform application business services based on the field data.

[0032] It should be noted that the migration of application business services is carried out according to the application business data package of the basic version, so as to ensure that the station-level monitoring station machine at the adjacent station can execute the application business services of the faulty station-level monitoring station machine in the shortest time, and then update the application business based on the static configuration data increment and dynamic historical data increment while executing the application business services.

[0033] It can be understood that when the fault of the station industrial control computer of the faulty station layer monitoring station machine is resolved, the cloud management platform will restore the static configuration data and historical dynamic data of the faulty station layer monitoring station machine stored in the station layer monitoring station machine of the adjacent station to the station industrial control computer of the faulty station layer monitoring station machine, thereby migrating the wide area network, business data (real-time monitoring data of the station's collection machine and station subsystem interface) and application business services of the station stored in the adjacent station monitoring station machine back to the detection station machine of the station, thereby realizing the recovery of the static data and historical dynamic data of the station.

[0034] Furthermore, the signal centralized monitoring center is also horizontally connected to CTC, RBC, TSRS, DM and other systems.

[0035] Specifically, Figure 3 As shown, the cloud management platform is constructed by a basic resource pool, including a computing resource pool cluster, a management cluster and network resources; wherein the network resources include a business network switch, a management network switch and a storage switch (redundant); when a horizontal system or a vertical system is connected, it is necessary to first isolate the regional boundaries through a firewall and then access the business network.

[0036] Specifically, the station machine data of each station-level monitoring station enters the signal centralized monitoring bureau center through the wide area network. The signal centralized monitoring bureau center forwards the relevant data to CTC, RBC, TSRS, DM and other systems. CTC, RBC, TSRS, DM and other systems realize management and data communication with the station machines through the monitoring wide area network.

[0037] Specifically, when the monitoring terminal queries station data, it will give priority to connecting to the application service of the signal centralized monitoring bureau center. When the signal centralized monitoring bureau center cannot provide normal application services, through the management and coordination of the cloud management center, the monitoring terminal can connect to the station machine to continue to provide limited application services.

[0038] The centralized signal monitoring system in this embodiment can realize data backup and recovery and uninterrupted service functions for application services even in the event of any single point failure in a station or a center.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present invention, which should be included in the scope of the technical solution for protection of the present invention.
