Referring to fig. 1 to 2, an embodiment of the present invention provides an automatic train monitoring system 100, where the automatic train monitoring system 100 is deployed with a server cluster, and the server cluster includes a management node 12 and a plurality of working nodes 14, at least two of the plurality of working nodes 14 can operate simultaneously, the management node 12 is used for monitoring network health of the working nodes 14, the working nodes 14 include a safe working node 16 and an unsafe working node 18, the unsafe working node 18 is used for operating front end software, back end software and interface software of the automatic train monitoring system 100, the safe working node 16 is used for performing data analysis service and operating a safe working node interface software 17, and each safe working node 16 corresponds to one train line.
The automatic train monitoring system 100 described above, when adding a train route, correspondingly adds the safe working nodes 16 and allocates the resources of part of the unsafe working nodes 18, thereby saving the time-space cost and server resources.
Specifically, the automatic train monitoring (Automatic Train Supervision) system is an important subsystem of the automatic train control (Automatic Train Control) system, is a distributed real-time supervision and control system integrating modern data communication, computers, networks and signal technologies, and the ATS subsystem is coordinated with other subsystems in the ATC system to jointly complete management and control of subway operation trains and signal equipment.
The automatic train monitoring system 100 provided by the invention is designed and deployed by the container cloud technology, a server cluster is deployed by using the container arranging tool kubernetes, and the server cluster comprises a management node 12 and a plurality of working nodes 14, and at least two of the working nodes 14 can run simultaneously.
The working nodes 14 comprise a safe working node 16 and an unsafe working node 18, the safe working node 16 is used for running safety-related application services, the unsafe working node 18 is used for running non-safety-related application services, the safe working node 16 and the unsafe working node 18 are independent two-part namespaces, and the safe working node 16 is arranged in a cluster network and used for being connected with other subsystems of a signal system through an external safe firewall safety network: computer interlock (CI-computer interlocking), zone Controller (ZC-Zone Controller) and vehicle-mounted control system (VOBC-vehicle on-board Controller) are used for information interaction, and CI related data analysis service, ZC related data analysis service, VOBC data analysis service and safety working node interface software 17 are operated in the safety working node 16, and the safety working node interface software 17 provides safety verification and load balancing service.
The front-end software and the interface software of the automatic train monitoring system 100 are run in the unsafe working node 18, and the back-end software provides: train identification tracking service, route handling service, operation adjustment service, train operation control service, train operation management service, alarm service, recording and playback service, and system maintenance service, the front-end software includes: the station diagram display module, the running diagram display module, the playback display module, the alarm display module and the maintenance interface display module, the interface software is used for information interaction and safety verification during information interaction, the interface software comprises an internal interface software 30 and an external interface software 28, the external interface software 28 is interface software for information interaction with a non-signal system, and the internal interface software 30 is interface software for information interaction with the safety work node 16.
When the train lines are expanded, the safety network of each line is isolated by using different firewalls, so when the lines are added, the safety working nodes 16 of the corresponding lines are correspondingly added, and meanwhile, partial resources of the non-safety working nodes 18 are allocated for the newly added lines. In the multi-line operation, the secure working nodes 16 of each line need to be deployed on different servers to perform physical isolation, but the non-secure working nodes 18 can perform resource allocation through the cloud platform to form a plurality of non-secure working nodes 18, and the plurality of non-secure working nodes 18 perform namespace isolation, i.e. virtual isolation in the cloud platform, so that time-space cost and server resources can be saved, and maximum utilization of the resources is realized.
In some embodiments, the working nodes 14 provide minimum resource management components for running front-end software, back-end software, interface software, data parsing services, and running secure working node interface software 17 of the automatic train monitoring system 100, with two minimum resource management components running the same service running on the two working nodes 14, respectively.
Thus, the design mode of the main and standby redundancy of the signal system can be satisfied, and the main and standby servers can be operated in a load-balanced manner.
In particular, the minimum resource management component (Pod) is the smallest unit in the container orchestration tool Kubernetes, which contains a set of containers in which services can be supported to run. In one example, when the server cluster initializes the operation node 14, the minimum number of the preset Pod is preset to be 2, and two pods running the same service are respectively run on two different physical machine resources, so that each physical machine can completely run all services related to the automatic train monitoring system 100, at this time, the two physical machines can be used as a primary server and a standby server running simultaneously, so that the requirement that the signal system needs to have the primary server and the standby server simultaneously can be met, and the two physical machines serving as the primary server and the standby server can both receive the processing data, so that the primary server and the standby server run in a load-balanced manner.
In some implementations, the load distribution policy of the minimum resource management component is a polling mode.
Therefore, when the data processing demand is large and the minimum resource management component is freely expanded in the peak period of train operation, the data processing speed can be effectively improved.
Specifically, kubernetes provides two load distribution strategies, each forwarding a request to a respective Pod for a Round Robin mode (Round Robin); a Session maintenance mode (Session Affinity) based on IP addresses, i.e. the 1 st forwarding of a request initiated by a certain IP address to a certain Pod, after which all requests initiated from the same IP address will be forwarded to the same Pod. When the polling mode is used and the data processing demand is large in the peak period of train operation, the speed of data processing can be increased when the Pod is freely expanded to meet the data processing demand.
When Pod is freely expanded, in one example, the minimum number of preset Pod is preset to be 2, one Pod is configured as a dual-core CPU, a 4G memory is preset for Pod, a CPU and memory utilization threshold is preset for Pod, when the CPU or memory utilization exceeds the preset utilization threshold, the Pod is automatically expanded, if the load is reduced, and if the number of Pod is higher than the configured minimum value, the number of Pod is reduced, but when the number of Pod reduced to be 2, two pods running the same service still respectively run on two different physical machine resources.
In some embodiments, the interface software includes external interface software 28, and the non-secure operating node 18 is configured to, when the non-signal system is transmitting data to the external interface software 28: receiving data transmitted by a non-signal system; and processing the data transmitted by the non-signal system and sending the data to preset equipment.
In this way, the non-secure working node 18 is enabled to interact with information from the non-signal system.
Specifically, the interface software of the non-secure working node 18 includes an external interface software 28, where the external interface software 28 is used to interact with the non-signal system, and when the external interface software 28 receives the data information of the non-signal system, the back-end software in the non-secure working node 18 determines the data type and processes the data, and then sends the processed data to a terminal device or the non-signal system, such as a ground charging system, a ground station broadcasting system, and so on.
In one example, the non-signal system transmits uplink state data, such as a state of a charging system, a state of a power system, a state of a broadcasting system, etc., to the non-secure operation node 18, and at this time, after the external interface software 28 receives the data, the back-end software performs data processing, and then sends the processed data to the front-end software for rendering, and finally, the relevant data is displayed on the terminal device. Downstream data of the non-signal system is received and processed by the back-end software, and then the information is sent to a communication system or other non-signal systems through the external interface software 28, wherein the downstream data of the non-signal system comprises the arrival information of the passenger information system and the arrival information of the passenger broadcasting system.
In some embodiments, the secure working node 16 is configured to interact with the signal system via the secure network, and when the signal system transmits information to the secure working node 16 via the secure network, the secure working node 16 is configured to: receiving information and performing security verification; in case the security check is successful, sending the information to the non-secure working node 18; the non-secure working node 18 is for: receiving information transmitted by the safety work node 16 and performing safety verification; in the event that the security check is successful, the information is processed and sent to a display interface of the automatic train monitoring system 100 for display.
In this way, the signaling system and the secure working node 16 are able to interact with information via the secure network.
Specifically, the security working node 16 is in the cluster network, externally connected with a security firewall security network, and is used for being connected with other subsystems of the signal system: computer interlocks (CI-computer interlocking), zone controllers (ZC-Zone controllers) and vehicle-mounted control systems (VOBC-vehicle on-board controllers) perform information interaction. The uplink state data of the subsystem of the signal system, such as the data of the state information frame of the train, the interlocking route opening information, the state of the turnout and the like, are sent to the non-safety module through the safety working node interface software 17 to be processed, rendered through the front end software, finally displayed on the display interface of the terminal equipment, and information interaction between the signal system and the safety working node 16 is realized. In one embodiment, the display interface may be displayed by a browser running on the terminal device.
In one example, after the state information of the CI uplink track section is sent to the security working node 16 through the security network, the security check and load balancing service module provided by the security working node interface software 17 receives the data, obtains the data from the CI subsystem according to the sender identifier in the data, calculates a CRC (Cyclic Redundancy Check ) value according to the protocol version number (V3.1) of the current CI subsystem and the automatic train monitoring system 100 and the electronic map data (0X 676E 324), performs consistency check on the CRC value and the CRC value in the state information, verifies that the value is consistent, considers that the data is valid, sends the data to the CI data analysis service for data analysis, and sends the data to the non-security module through the security check and load balancing service provided by the security working node interface software 17 for processing and finally displaying on the display interface of the terminal device after the analysis is completed.
In some embodiments, the interface software includes internal interface software 30, and the secure working node interface software 17 and internal interface software 30 communicate after the security check is successful.
Thus, the safety and stability of the communication connection can be ensured.
Specifically, the internal interface software 30 running in the non-secure working node 18 is used to establish communication with the secure working node interface software 17 for information interaction, and the communication mode of the internal interface software 30 and the secure working node interface software 17 adopts a websocket mode, so that when a communication connection is established, the internal interface software 30 and the secure working node interface software 17 can complete a handshake, and a persistent connection can be directly established between the internal interface software 30 and the secure working node interface software 17 for bidirectional data transmission. Before the connection communication is initially established, the secure working node 16 continuously and actively transmits a heartbeat packet to the internal interface software 30, wherein the heartbeat packet includes a CRC value checked by the secure working node 16 under the current line version, the CRC value is generated according to the version number and time for the software version release, in one example, when the automatic train monitoring system 100 performs upgrading deployment on a certain line, the communication connection between the secure working node 16 and the non-secure working node 18 is automatically disconnected, and when the non-secure working node 18 finishes the initial upgrading and the secure working node 16 does not finish the upgrading, the old version secure working node 16 actively and continuously transmits the heartbeat packet to the non-secure working node 18, and because the software module configures the communication domain name unchanged, the CRC value changes due to the version upgrading, and therefore websocket fails in every connection establishment. When the upgrade of the secure working node 16 is completed, the CRC values of the secure working node 16 and the non-secure working node 18 are identical at this time, and the communication establishment is successful. After the secure working node interface software 17 and the internal interface 30 establish communication, the secure working node 16 continues to actively send heartbeat packets to the internal interface software 30 to detect whether the communication connection is in a normal state. The internal interface software 30 and the security working node interface software 17 perform security check before establishing communication connection, and establish communication connection under the condition that the security check passes, so that the security of communication connection can be ensured, and simultaneously, heartbeat packets are continuously sent after the communication connection is established, so that the stability of communication connection can be ensured.
In some embodiments, the automatic train monitoring system 100 further includes a terminal device;
the terminal device is used for displaying the data transmitted by the working node 14, receiving the user command and transmitting the user command to the signal system through the working node 14.

The user can operate the page provided by the front-end software through the display interface of the terminal device, including a station diagram display module, an operation diagram display module, a playback display module, an alarm display module, a maintenance interface display module and the like in the front-end software, and can acquire station diagram information, operation diagram information, alarm information and the like through the display interface of the terminal device, and simultaneously, the user issues instructions to the software operated in the working node 14 through the terminal device.

After the safety check is passed, the target system issued by the command is judged according to the type and the parameters of the command, a CRC value is generated according to the protocol version number between the current automatic train monitoring system 100 and other subsystems and the electronic map data, the CRC value is added into the command and issued to the other subsystems of the signal system, if the safety check is not passed, the command is considered invalid, and the command is not issued any more. By carrying out safety verification on the issued command, the command issued by the user through the terminal equipment can be ensured to be safely and accurately transmitted.
In one example, after a user issues a train emergency brake release confirmation command to the terminal device, the command is issued to the unsafe working node 18, the internal interface software 30 generates a CRC value 0X89ED35 according to three parameters of the command time (15:30), the command type (0X 56) and the command parameter (101) and the current line version (V1.3.3) through a unified algorithm, the CRC value is used as a fourth parameter of the command, the command is issued to a safety check and load balancing service of the safe working node interface software 17, after the service accepts the command, the CRC value is calculated according to the first three parameters, the CRC value 0X89ED35 is calculated to be consistent with the CRC value in the issued command, the command is considered to be valid, after the parameter is confirmed, the command is judged to be a command sent to the train 101, a CRC value is generated according to the protocol version (V3.2) between the current automatic train monitoring system 100 and the VOBC subsystem, and the electronic map data (0X 49CA 35), and the CRC value is added to the command and the command is issued.
In some embodiments, the server cluster is comprised of local server resources, or server resources satisfying an amount are allocated by a uniform resource managed cloud platform.
Thus, the deployment mode of the server cluster can be selected according to the requirement.
Specifically, when the server cluster is deployed, local servers can be arranged in different areas according to regional differences of the lines, the deployment method can ensure effective transmission of data, the servers can be deployed in one place, and server resources meeting the amount are distributed to the lines in different areas through the cloud platform.
