[0002] The rail transit broadcasting and communication system is an important component of the rail transit communication system. Its main functions include passenger information broadcasting (such as arrival reminders and transfer guidance), emergency event notification (such as fire and fault alarms), and dispatching and command communication (such as communication between drivers and the control center).

[0004] In related technologies, when a device in a rail transit broadcasting and communication system malfunctions, maintenance personnel typically determine the scope of the malfunction's impact based on subjective experience. However, due to the complexity of rail transit broadcasting and communication systems and the diversity of malfunctions, maintenance personnel may find it difficult to comprehensively and accurately determine the scope of the malfunction's impact, and determining the scope of the malfunction's impact is time-consuming, which can easily lead to the risk of the malfunction spreading.

This invention enables a more accurate and efficient determination of the impact range of a fault when any device in a rail transit broadcasting and communication system fails.

[0007] This invention provides a method for predicting the scope of a fault's impact, comprising the following steps.

[0008] Fault monitoring of equipment in the target rail transit broadcasting and communication system; If a fault is detected in any device in the target rail transit broadcasting and communication system, the target device and / or target data transmission link affected by the fault are determined in the target rail transit broadcasting and communication system based on the service analysis diagram corresponding to the target rail transit broadcasting and communication system. In the business analysis diagram of the target rail transit broadcasting and communication system, any node represents a device in the target rail transit broadcasting and communication system.

The operating data of the switch includes at least one of the following: port status information, traffic data, and number of error packets. If the status of any port is determined to be disconnected based on the status information of any port of any switch in the target rail transit broadcasting and communication system, then the device connected to that port is determined to be faulty. If the traffic data of any port of any switch in the target rail transit broadcasting and communication system exceeds the traffic threshold, then the device connected to that port is determined to be faulty. If the number of erroneous packets of any port of any switch in the target rail transit broadcasting and communication system exceeds the number threshold, then the device connected to that port is determined to be faulty.

[0015] In the business analysis diagram of the target rail transit broadcasting and communication system, any node represents a device in the target rail transit broadcasting and communication system.

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0028] In the description of this application, "and / or" means at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0029] The following is combined Figures 1 to 3 This invention describes the method for predicting the scope of fault impact.

[0030] Figure 1 This is a flowchart illustrating the fault impact range prediction method provided by the present invention, as shown below. Figure 1 As shown, the method includes the following steps: Step 101, fault monitoring of equipment in the target rail transit broadcasting and communication system.

[0031] It should be noted that the execution subject of this embodiment of the invention is a fault impact range prediction device. The fault impact range prediction device can be configured in the target rail transit broadcasting and communication system, or it can be configured in an electronic device such as a peripheral computer or peripheral server outside the target rail transit broadcasting and communication system.

[0032] Specifically, the target rail transit broadcasting and communication system is the prediction object of the fault impact range prediction method provided by this invention. Based on the fault impact range prediction method provided by this invention, the impact range of any equipment in the target rail transit broadcasting and communication system can be determined more accurately and efficiently, thereby enabling a more timely response to equipment within the impact range of the fault and reducing the risk of the fault spreading.

[0033] It is understood that the target rail transit broadcasting and communication system in the embodiments of the present invention can be determined based on actual needs, and the present invention does not impose specific limitations on the target rail transit broadcasting and communication system.

[0034] It is understood that the target rail transit broadcasting and communication system may include, but is not limited to, a central digital broadcasting host, broadcasting control box, central broadcasting equipment, station broadcasting equipment, vehicle broadcasting equipment, various switches (including broadcasting center switches, broadcasting station switches and broadcasting vehicle switches, etc.) and loudspeakers installed in stations and trains.

[0035] In this embodiment of the invention, fault monitoring of equipment in the target rail transit broadcasting and communication system can be performed through numerical analysis, mathematical statistics, and deep learning techniques.

[0036] For example, in this embodiment of the invention, a fault monitoring module in the target rail transit broadcasting and communication system can be used to monitor the equipment in the target rail transit broadcasting and communication system for faults. Specifically, the fault monitoring module can utilize a multi-source sensor network deployed in various devices of the target rail transit broadcasting and communication system to continuously collect monitoring data such as the operating parameters, signal transmission quality, and environmental interference data of the equipment in the target rail transit broadcasting and communication system. Based on this monitoring data, correlation analysis can be performed to determine whether a fault has occurred in the equipment of the target rail transit broadcasting and communication system.

[0037] Specifically, the aforementioned fault monitoring module can perform millisecond-level sampling of the operating parameters of the equipment in the target rail transit broadcasting and communication system (such as audio signal distortion, network packet loss rate, and equipment temperature), obtain fault characteristics through multimodal data fusion, and then, based on the aforementioned fault characteristics, use a pre-trained fault diagnosis model, such as a hidden Markov model built based on transfer learning algorithms or a time series prediction model built based on long short-term memory networks (LSTM), to determine whether the equipment in the target rail transit broadcasting and communication system has malfunctioned.

[0038] As an optional embodiment, fault monitoring of equipment in the target rail transit broadcasting and communication system includes: acquiring the operating data of the switch in the target rail transit broadcasting and communication system, wherein the operating data of the switch includes at least one of the following: port status information, traffic data, and number of error packets. It should be noted that, because the loudspeaker equipment in rail transit broadcasting and communication systems is deployed in arrays in open spaces such as stations and carriages, and is numerous and geographically dispersed, the fault monitoring modules in related technologies for rail transit broadcasting and communication systems often find it difficult to effectively monitor the faults of the loudspeaker equipment in rail transit broadcasting and communication systems.

[0039] Furthermore, the loudspeaker equipment in rail transit broadcasting and communication systems is typically connected to main equipment such as central broadcasting equipment, station broadcasting equipment, or vehicle-mounted broadcasting equipment via switches. When a device in a rail transit broadcasting and communication system malfunctions, maintenance personnel, relying on subjective experience, may find it difficult to comprehensively and accurately determine the scope of the malfunction's impact due to the lack of knowledge about the devices connected to the switches in the system.

[0040] Therefore, in this embodiment of the invention, it is possible to determine whether the downstream equipment of the aforementioned switch has malfunctioned based on the operating data of the switch in the target rail transit broadcasting and communication system.

[0041] Specifically, in this embodiment of the invention, the operating data of the switch can be obtained in an encrypted manner through the SNMP (Simple Network Management Protocol) v3 protocol, including at least one of the following: the status information of the switch ports, traffic data, and the number of error packets.

[0042] It is understood that in the embodiments of the present invention, the number of switches in the target rail transit broadcast communication system can be multiple, and the number of ports of any switch can be multiple.

[0043] If the status of any port is determined to be disconnected based on the status information of any port of any switch in the target rail transit broadcast communication system, the device connected to any port is determined to be faulty. If the traffic data of any port of any switch in the target rail transit broadcast communication system exceeds the traffic threshold, the device connected to any port is determined to be faulty. If the number of erroneous packets of any port of any switch in the target rail transit broadcast communication system exceeds the number threshold, the device connected to any port is determined to be faulty.

[0044] It should be noted that the port of the switch maintains the communication link of the device through a dual mechanism of physical layer (such as cable connection) and data link layer (such as link protocol negotiation). When the port status of the switch is disconnected (DOWN), it indicates that the physical link of the above port is interrupted or the link layer protocol negotiation fails. However, the rail transit broadcast communication system has extremely high requirements for the stability of the device connection, and normal equipment should always keep the link active.

[0045] Therefore, in this embodiment of the invention, if the status information of the port of the aforementioned switch is determined to be a port (DOWN) based on the status information of any port of any switch in the target rail transit broadcast communication system, it is determined that the downstream device of the port of the aforementioned switch has failed (such as power failure, interface damage, or network configuration error).

[0046] It should be noted that the traffic of the switch ports in the rail transit broadcast communication system is within a stable range due to system design constraints. However, an abnormal surge in traffic at the switch ports is usually caused by equipment-level faults (such as equipment crashes leading to continuous retransmissions, protocol stack crashes causing broadcast storms, or hardware failures generating a large number of error frames).

[0047] Therefore, in this embodiment of the invention, if the traffic data of any port of any switch in the target rail transit broadcast communication system exceeds the traffic threshold, it is determined that the downstream device of the aforementioned port of the aforementioned switch has failed.

[0048] It should be noted that the flow threshold in the embodiments of the present invention can be determined based on prior knowledge and / or actual conditions. The embodiments of the present invention do not impose specific limitations on the aforementioned flow threshold.

[0049] It should be noted that erroneous packets (such as CRC check failures, frame fragments, and ultra-short packets) are a direct indication of data link layer transmission quality degradation, typically caused by hardware failures (such as damaged network card chips or abnormal interface circuits), physical link instability (such as poor contact or electromagnetic interference), or protocol stack anomalies (such as buffer overflows or driver errors). A persistently high frequency of erroneous packets can be attributed to device-side transmit / receive module failures, such as overheating leading to performance degradation of the codec chip, or firmware defects causing abnormal data frame encapsulation.

[0050] Therefore, in this embodiment of the invention, if the number of erroneous packets on any port of any switch in the target rail transit broadcast communication system exceeds a certain threshold, it is determined that the downstream device of the aforementioned port of the aforementioned switch has failed.

[0051] It should be noted that the quantity threshold in the embodiments of the present invention can be determined based on prior knowledge and / or actual circumstances. The embodiments of the present invention do not impose specific limitations on the aforementioned quantity threshold.

[0052] Optionally, in this embodiment of the invention, fault monitoring of the broadcast zone status can also be achieved by analyzing the collected status information of the power amplifier. The software operating status can be determined by analyzing the number of running software processes within the digital broadcast host.

[0053] This invention, through multi-dimensional real-time monitoring of the operating data of the switch in the target rail transit broadcasting and communication system, enables accurate diagnosis and rapid response to faults in the downstream equipment of the switch in the target rail transit broadcasting and communication system, effectively monitors the speaker equipment in the target rail transit broadcasting and communication system, and provides a more accurate data basis for subsequent prediction of the scope of fault impact.

[0054] Step 102: If a fault is detected in any device in the target rail transit broadcasting and communication system, based on the service analysis diagram corresponding to the target rail transit broadcasting and communication system, determine the target device and / or target data transmission link affected by the fault in the target rail transit broadcasting and communication system; wherein, any node in the service analysis diagram corresponding to the target rail transit broadcasting and communication system represents a device in the target rail transit broadcasting and communication system, and any two nodes in the service analysis diagram corresponding to the target rail transit broadcasting and communication system are connected by a line segment, indicating that there is a data transmission link between the two devices corresponding to the two nodes.

[0055] It should be noted that the fault impact range prediction device in this embodiment of the invention can receive fault information sent from the fault monitoring module in the target rail transit broadcasting and communication system through the TIAS interface module. This fault information can be used to indicate that any device in the target rail transit broadcasting and communication system has malfunctioned.

[0056] In this embodiment of the invention, upon receiving the aforementioned fault information, it can be determined that any device in the target rail transit broadcasting and communication system has malfunctioned.

[0057] Optionally, in this embodiment of the invention, the fault information sent by the fault monitoring module in the target rail transit broadcasting and communication system can be a device fault point table. The aforementioned device fault point table can describe, in tabular form, the correspondence between the identification information of the faulty equipment in the target rail transit broadcasting and communication system, the fault type, and the time of the fault occurrence, etc.

[0058] It is understood that the faulty device in the target rail transit broadcasting and communication system monitored in the embodiments of the present invention can also be the downstream device of the switch monitored based on the operation data of the switch in the target rail transit broadcasting and communication system.

[0059] If a fault is detected in any device in the target rail transit broadcasting and communication system, the device and / or data transmission link that will be affected by the fault of the aforementioned device can be identified in the target rail transit broadcasting and communication system based on the service analysis diagram corresponding to the target rail transit broadcasting and communication system, through methods such as condition judgment, mathematical statistics or deep learning technology, and designated as the target device and / or target data transmission link.

[0060] Once the target device and / or target data stream affected by the above-mentioned fault are identified, the scope of the fault's influence can be determined, and then response measures such as fault detection, fault elimination, and fault analysis can be implemented for the target device and / or target data transmission link.

[0061] It should be noted that the service analysis diagram corresponding to the target rail transit broadcasting and communication system in this embodiment of the invention can be generated based on the actual equipment situation and the actual data interaction relationship between the equipment in the target rail transit broadcasting and communication system. Figure 2 This is a schematic diagram of the service analysis diagram corresponding to the target rail transit broadcasting and communication system in the fault impact range prediction method provided by this invention. For example... Figure 2 As shown, the service analysis diagram corresponding to the target rail transit broadcasting and communication system is an end-to-end service analysis diagram, consisting of nodes and line segments connecting two nodes. Any node in the service analysis diagram of the target rail transit broadcasting and communication system can represent a device within the system. The connection between any two nodes via a line segment indicates a data transmission link between the two devices corresponding to those two nodes, allowing data transmission between them. The nodes in the service analysis diagram of the target rail transit broadcasting and communication system can be represented using Scalable Vector Graphics (SVG).

[0062] Optionally, such as Figure 2 As shown, in the service analysis diagram corresponding to the target rail transit broadcast communication system in this embodiment of the invention, different colored line segments can also be used to represent the data transmission type of the data transmission link between the devices corresponding to the two connected nodes. Figure 2 The blue line segment in the diagram indicates that the data transmission type between the two connected nodes is non-audio data. Figure 2 The green line segment in the diagram indicates that the data transmission type of the data transmission link between the two connected nodes is audio data.

[0063] As an optional embodiment, based on the service analysis diagram corresponding to the target rail transit broadcast communication system, the target equipment and / or target data transmission link affected by the fault in the target rail transit broadcast communication system are determined, including: if it is determined from the service analysis diagram corresponding to the target rail transit broadcast communication system that there is a data transmission link between any device and other devices in the target rail transit broadcast communication system, the other devices are determined as target devices, and the data transmission link between any device and other devices in the target rail transit broadcast communication system is determined as the target data transmission link.

[0064] It should be noted that if, based on the service analysis diagram corresponding to the target rail transit broadcasting and communication system, it is determined that there is no data transmission link between the faulty device in the target rail transit broadcasting and communication system and any other device in the target rail transit broadcasting and communication system, the scope of the aforementioned fault can be determined to be empty.

[0065] Optionally, if it is determined from the service analysis diagram corresponding to the target rail transit broadcast communication system that there is a data transmission link between the faulty device in the target rail transit broadcast communication system and multiple other devices in the target rail transit broadcast communication system, the device among the other multiple devices that receives data sent by the faulty device through the data transmission link can be identified as the target device affected by the fault. Then, the data transmission link between the faulty device and the target device can be identified as the target data transmission link affected by the fault.

[0066] It should be noted that, in this embodiment of the invention, an end-to-end alarm analysis point table corresponding to the target rail transit broadcast communication system can be maintained. After determining the target equipment and / or target data transmission link affected by the fault, the correspondence between the identification information of the faulty equipment in the target rail transit broadcast communication system and the identification information of the target equipment and the target data communication link affected by the fault can be added to the end-to-end alarm analysis point table corresponding to the target rail transit broadcast communication system, thereby updating the end-to-end alarm analysis point table corresponding to the target rail transit broadcast communication system. The target data transmission link can be determined based on the correspondence between the identification information of the faulty equipment in the target rail transit broadcast communication system and the identification information of the target equipment affected by the fault.

[0067] As an optional embodiment, after determining the target equipment and / or target data transmission link affected by the fault in the target rail transit broadcasting and communication system based on the service analysis diagram corresponding to the target rail transit broadcasting and communication system, the method further includes: highlighting the node corresponding to any device in the service analysis diagram corresponding to the target rail transit broadcasting and communication system displayed on the display device in the target rail transit broadcasting and communication system, and highlighting the node corresponding to the target equipment affected by the fault and / or flashing the line segment corresponding to the target data transmission link affected by the fault.

[0068] It should be noted that, Figure 3 This is a schematic diagram of the display interface of the display device in the target rail transit broadcasting and communication system in the fault impact range prediction method provided by this invention. (See diagram for example.) Figure 3As shown, the target rail transit broadcasting and communication system in this embodiment of the invention may include a display device. The display interface of the display device may display the service analysis diagram corresponding to the target rail transit broadcasting and communication system for operation and maintenance personnel to view.

[0069] After identifying the target equipment and / or target data transmission link affected by the fault in the target rail transit broadcasting and communication system, the faulty equipment in the target rail transit broadcasting and communication system can be highlighted in the service analysis diagram corresponding to the target rail transit broadcasting and communication system displayed on the display interface of the aforementioned display device. The nodes corresponding to the target equipment affected by the fault can be highlighted, and / or the line segments corresponding to the target data transmission link affected by the fault can be flashed. This can more intuitively prompt the operation and maintenance personnel to respond to the aforementioned target equipment and / or target data transmission link.

[0070] Optionally, based on the service analysis diagram corresponding to the target rail transit broadcasting and communication system, the target equipment and / or target data transmission link affected by the fault in the target rail transit broadcasting and communication system can be identified. Alarm information carrying the identification information of the aforementioned target equipment and / or target data transmission link can also be generated, and then the aforementioned alarm information (such as...) can be displayed on the display interface of the display device in the target rail transit broadcasting and communication system. Figure 3 (As shown).

[0071] Optionally, in this embodiment of the invention, the updated end-to-end alarm analysis point table corresponding to the target rail transit broadcasting and communication system can also be displayed in real time on the display interface of the display device in the target rail transit broadcasting and communication system.

[0072] As an optional embodiment, when adding, changing, or removing equipment in the target rail transit broadcasting and communication system, the corresponding service analysis diagram of the target rail transit broadcasting and communication system is updated.

[0073] Specifically, when adding equipment to the target rail transit broadcasting and communication system, nodes corresponding to the newly added equipment can be added to the service analysis diagram of the target rail transit broadcasting and communication system. Based on the data transmission relationship between the newly added equipment and other equipment, line segments connecting the newly added equipment and other equipment can be drawn in the service analysis diagram of the target rail transit broadcasting and communication system.

[0074] If the equipment in the target rail transit broadcasting and communication system undergoes changes (such as location relocation, function adjustment, change of connection relationship, or modification of interface parameters), the attribute information of the corresponding node of the above equipment or the connection relationship between the above node and other nodes can be changed in the business analysis diagram of the target rail transit broadcasting and communication system.

[0075] If equipment in the target rail transit broadcasting and communication system is removed, the node corresponding to the removed equipment can be deleted from the service analysis diagram of the target rail transit broadcasting and communication system, and the line segments between the removed node and other nodes can be cleared.

[0076] In this embodiment of the invention, when adding, changing, or reducing equipment in the target rail transit broadcasting and communication system, updating the service analysis diagram corresponding to the target rail transit broadcasting and communication system can ensure the consistency of the topology between the graphical interface and the actual system, and can ensure the accuracy of fault range determination based on the service analysis diagram corresponding to the target rail transit broadcasting and communication system.

[0077] This invention, in the event of a fault detected in any device within a target rail transit broadcasting and communication system, identifies the affected target device and / or target data transmission link based on the corresponding service analysis diagram of the target rail transit broadcasting and communication system. Through topology-driven intelligent analysis of the fault impact range, it more accurately and efficiently determines the impact range of the fault in the rail transit broadcasting and communication system, thereby enabling a more timely response to the impact range of the fault and improving the overall availability and operational efficiency of the rail transit broadcasting and communication system.

[0078] The fault impact range prediction method provided by this invention designs an end-to-end service analysis diagram for the rail transit broadcasting and communication system. Based on the existing equipment fault point table of the rail transit broadcasting and communication system and the corresponding service analysis diagram, it can determine the impact range of the fault, thereby obtaining an end-to-end alarm analysis point table for the rail transit broadcasting and communication system. Linking the end-to-end alarm analysis point table with the corresponding service analysis diagram allows for a more intuitive and timely prompting of operators to respond to the aforementioned fault impact range.

[0079] The fault impact range prediction method provided by this invention simplifies the network structure of the rail transit broadcasting and communication system by using core nodes in the data service flow, making external interfaces clearer and reducing the difficulty of fault diagnosis. The digital broadcasting host receives fault information sent from the fault monitoring module in the target rail transit broadcasting and communication system through the TIAS interface module, and controls and operates the terminal equipment through its own internal modules.

[0080] The fault impact range prediction method provided by this invention enables visualization of fault alarms in rail transit broadcasting and communication systems, rapid location of fault points, and shortens fault investigation time. It also allows for fault impact analysis of rail transit broadcasting and communication systems (primarily based on service flow and connection nodes of the faulty node, providing the impact range and troubleshooting node equipment), offering fault handling suggestions, and improving fault handling efficiency. Furthermore, it enables monitoring of the digital broadcasting host software process, allowing for constant monitoring of the software's operational health.

[0081] Figure 4 This is a schematic diagram of the fault impact range prediction device provided by the present invention. The following is in conjunction with… Figure 4 The fault impact range prediction device provided by this invention is described below. The fault impact range prediction device described below can be referred to in correspondence with the fault impact range prediction method provided by this invention described above. For example... Figure 4 As shown, the device includes a fault monitoring module 401 and a range determination module 402.

[0082] Fault monitoring module 401 is used to monitor faults in equipment of the target rail transit broadcasting and communication system; The range determination module 402 is used to determine the target equipment and / or target data transmission link affected by the fault in the target rail transit broadcast communication system based on the service analysis diagram corresponding to the target rail transit broadcast communication system when a fault is detected in any equipment in the target rail transit broadcast communication system. In the business analysis diagram of the target rail transit broadcasting and communication system, any node represents a device in the target rail transit broadcasting and communication system. Any two nodes in the business analysis diagram of the target rail transit broadcasting and communication system are connected by a line segment, indicating that there is a data transmission link between the two devices corresponding to the two nodes.

[0083] Specifically, the fault monitoring module 401 and the range determination module 402 are electrically connected.

[0084] The fault monitoring module 401 is specifically used to acquire the operating data of the switches in the target rail transit broadcasting and communication system. The operating data of the switches includes at least one of the following: port status information, traffic data, and number of error packets. If the status of any port of any switch in the target rail transit broadcasting and communication system is determined to be disconnected based on the status information of any port of any switch, the module determines that the device connected to any port has failed. If the traffic data of any port of any switch in the target rail transit broadcasting and communication system exceeds the traffic threshold, the module determines that the device connected to any port has failed. If the number of error packets of any port of any switch in the target rail transit broadcasting and communication system exceeds the number threshold, the module determines that the device connected to any port has failed.
