[0020] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application, and are not used to limit the present application.

[0021] In order to better understand the technical solutions of the present application, the specific embodiments will be described in detail below with reference to the drawings in the specification.

[0022] The main solution of the embodiment of the present application is: collecting dangerous information in a preset range of railway; transmitting the collected dangerous information to an edge computing node for processing; sending the processed dangerous information to the vehicle terminal through a one-way channel in the form of short message, and the one-way sending prohibits the vehicle terminal from responding or feeding back through the same short message channel.

[0023] Due to the limitations of traditional security and protection systems in real-time and security, the limitations are increasingly prominent. Although the existing two-way communication mode can realize information interaction, it faces security risks such as data leakage and malicious attacks, and it is difficult to ensure that critical early warning information is timely and accurately delivered to the driver.

[0024] The present application provides a solution, which transmits the collected dangerous information to an edge computing node for processing, so as to ensure that the critical early warning information is safely and low-delay delivered to the driver; at the same time, the processed dangerous information is sent to the vehicle terminal through a one-way channel in the form of short message, which completely avoids the security risk of two-way communication, improves the high-speed rail operation safety and emergency response efficiency, provides reliable real-time early warning protection for the high-speed rail intelligent security and protection system, and effectively ensures the high-speed rail operation safety and stable operation.

[0025] It should be noted that the execution subject of the present embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or a high-speed rail intelligent security and protection real-time early warning device capable of realizing the above functions. The present embodiment and the following embodiments will be described below taking the high-speed rail intelligent security and protection real-time early warning device as an example.

[0026] Based on this, the present embodiment provides a high-speed rail intelligent security and protection real-time early warning method, which is described in detail with reference to Figure 1 , Figure 1The flowchart provided in this embodiment of the high-speed rail intelligent security real-time early warning method.

[0027] In this embodiment, the high-speed rail intelligent security real-time early warning method includes steps S10-S30: Step S10: Collecting dangerous information within a preset range of the railway.

[0028] It should be noted that the system will first scan and monitor the preset monitoring range of the railway line. This range can include key areas such as tracks, bridges, tunnels, and slopes. Through the deployment of sensors (such as cameras, vibration sensors, temperature sensors, etc.) or other monitoring means, the system will collect dangerous information in real time or periodically, such as track deformation, foreign object intrusion, equipment abnormalities, and signs of natural disasters (such as landslide warnings).

[0029] Step S20: Transmitting the collected dangerous information to the edge computing node for processing.

[0030] It should be understood that the collected raw dangerous information will be quickly transmitted to the nearest edge computing node. The edge computing node has certain computing capabilities, which will process and analyze these information in real time. For example, identifying abnormal objects in images, analyzing sensor data to determine potential risks, assessing the level and urgency of danger, etc. The purpose of this step is to quickly filter and refine the key information that needs immediate attention and processing, reducing unnecessary data transmission and delay.

[0031] Step S30: Sending the processed dangerous information through a one-way channel in the form of a short message to the vehicle-mounted terminal, and the one-way sending prohibits the vehicle-mounted terminal from responding or feeding back through the same short message channel.

[0032] It should be noted that the key information processed by the edge computing node, which confirms the existence of danger and needs to be immediately notified to the train driver, will be sent to the vehicle-mounted terminal of the train through the preset short message channel. The key here is "one-way channel": information can only be sent from the system to the vehicle-mounted terminal, and the vehicle-mounted terminal cannot send any response or feedback information to the system through this same short message channel. This design is mainly to ensure that in emergency situations, danger warnings can be quickly, reliably and undisturbedly communicated to the driver, avoiding the occupation or blocking of this important warning channel by the vehicle-mounted terminal trying to respond, ensuring the timeliness and effectiveness of information transmission.

[0033] In the embodiment, the high-speed rail intelligent security real-time early warning method comprises: collecting dangerous information within a preset range of the railway; transmitting the collected dangerous information to an edge computing node for processing; and sending the processed dangerous information to a vehicle-mounted terminal through a one-way channel in the form of a short message, wherein the one-way sending prohibits the vehicle-mounted terminal from responding or feeding back through the same short message channel. By transmitting the collected dangerous information to the edge computing node for processing, it can be ensured that the key early warning information is safely and low-delay delivered to the driver; and by sending the processed dangerous information to the vehicle-mounted terminal through a one-way channel in the form of a short message, the safety risk of two-way communication is completely avoided, the high-speed rail operation safety and emergency response efficiency are improved, reliable real-time early warning protection is provided for the high-speed rail intelligent security system, and the safe and stable operation of the high-speed rail is effectively ensured.

[0034] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as the above-mentioned first embodiment can be referred to the above introduction, and will not be described in detail hereinafter. On this basis, please refer to Figure 2 , Figure 2 The flowchart provided in the second embodiment of the high-speed rail intelligent security real-time early warning method of the present application. In step S20, the high-speed rail intelligent security real-time early warning method further comprises: Step S201: obtaining the device hardware fingerprint in the dangerous information.

[0035] It should be understood that in the collected dangerous information, the device hardware fingerprint associated therewith is extracted. The hardware fingerprint usually refers to a physical or logical identifier unique to a device and difficult to counterfeit, such as the serial number, MAC address, specific hardware configuration combination, or even a unique hash value generated by hardware features of the device. This fingerprint is used to uniquely identify the specific sensor or monitoring device that generates the dangerous information.

[0036] Step S202: performing trusted data source verification on the dangerous information according to the device hardware fingerprint.

[0037] It should be noted that the source of the dangerous information is verified using the obtained device hardware fingerprint. The system will maintain a list of trusted devices or use some authentication mechanism to check whether the hardware fingerprint belongs to an authorized and trusted device. If the hardware fingerprint matches successfully, it is confirmed that the information is collected and sent by a legal and authorized device, and it is considered that the dangerous information has passed the trusted data source verification. This step is to ensure that the source of the information is reliable and trustworthy, and to prevent false or malicious devices from sending false dangerous information.

[0038] Step S203: when the dangerous information passes the trusted data source verification, a dispatcher private key is used to append a signature to the dangerous information.

[0039] It should be understood that, in order to further enhance the integrity and non-repudiation of the information, the system will use the private key of the dispatcher (or its representative system) to digitally sign the verified dangerous information after the dangerous information is successfully verified by the trusted data source. The "additional signature" here means adding a signature data block generated by the dispatcher's private key to the original information or processed information. This signature can verify that the sender of the information is indeed the dispatcher (or its authorized system) holding the private key, and the information has not been tampered with after signing. The receiver (such as the vehicle terminal or subsequent processing system) can use the corresponding public key to verify the signature to confirm the authenticity and integrity of the information.

[0040] In the embodiment, the device hardware fingerprint in the dangerous information is obtained; the dangerous information is verified by a trusted data source according to the device hardware fingerprint; and when the dangerous information is verified by the trusted data source, the dangerous information is additionally signed by using a private key of a dispatcher. This series of steps ensures that the source of the railway dangerous information is trusted, the content is not tampered with, and the authorized publisher of the information is clear, thereby improving the security and reliability of the entire safety warning system.

[0041] Based on the first embodiment and / or the second embodiment of the present application, in the third embodiment of the present application, the same or similar contents as the above-mentioned first embodiment and second embodiment can be referred to the above description, and will not be repeated hereinafter. On this basis, please refer to Figure 3 , Figure 3 The flowchart provided in the third embodiment of the high-speed rail intelligent security real-time early warning method of the present application. Before step S30, the high-speed rail intelligent security real-time early warning method further comprises: Step S301: Construct a one-way channel for the dangerous information, wherein the one-way channel comprises a collection end, a manual auditing end, a short message gateway, and a vehicle terminal connected in sequence.

[0042] It should be noted that the core feature of this channel is "one-way". This means that the direction of information flow is strictly fixed, and can only be along the "collection end → artificial audit end → SMS gateway → vehicle terminal" direction. All dangerous information about railway safety can only start from the collection device at the front end, be confirmed by artificial audit, be sent by the SMS gateway, and finally reach the vehicle terminal on the train.

[0043] It should be understood that the core feature of this channel is "one-way". This means that the direction of information flow is strictly fixed, and can only be along the "collection end → artificial audit end → SMS gateway → vehicle terminal" direction. All dangerous information about railway safety can only start from the collection device at the front end, be confirmed by artificial audit, be sent by the SMS gateway, and finally reach the vehicle terminal on the train.

[0044] Further, the design of this one-way channel is to ensure that dangerous information can be quickly, reliably and undisturbedly transmitted from the front-end monitoring point to the train driver. By introducing the artificial audit link, the accuracy of the information is improved; and the characteristics of one-way transmission ensure that in emergency situations, critical warning information will not be blocked or delayed by any response of the vehicle terminal, and the driving safety is maximized.

[0045] After step S301, further comprising: Step S302: Monitor the status of the one-way data channel.

[0046] It should be noted that the system will continuously check and evaluate the operation of the one-way data channel from the "collection end" through the "artificial audit end", "SMS gateway" to the "vehicle terminal". This is like constantly observing whether an important pipeline is unobstructed, and the system will pay attention to whether the data can be normally and timely transmitted from one end to the other end.

[0047] Step S303: When it is monitored that the one-way data channel reaches the preset channel fuse condition, switch to the preset backup channel for communication.

[0048] It should be understood that the system pre-sets some explicit "danger signals" or "failure indicators", when the state of the channel reaches or exceeds these indicators, it is considered that the channel has been unable to work reliably, and needs to be stopped immediately. These pre-set conditions include: the number of consecutive failed attempts to send data reaches a pre-set threshold: if in a short period of time (such as several minutes or seconds in a row), attempts to send dangerous information through this channel, but each time failed (such as the short message sending does not go out), and the number of failures accumulated to a pre-set number (such as 5 consecutive failures), this triggers the fuse condition. The signal strength is lower than the pre-set threshold: the signal strength of one or more links of the one-way channel (especially the part involving wireless communication, such as the signal received by the mobile network or the vehicle terminal from the short message gateway) becomes too weak. If this signal strength continues to be lower than a pre-set minimum acceptable level (threshold), it means that the channel is unstable or about to be interrupted, which triggers the fuse. The time of missing positioning information exceeds the threshold: although the positioning information itself is not necessarily the content of the channel transmission, its loss reflects the problem of the network environment or the state of the relevant device (such as the vehicle terminal, even the audit terminal or the gateway device). If the system detects that the positioning information of the relevant device cannot be obtained continuously, and this time exceeds the pre-set tolerance limit (such as 10 minutes of continuous positioning), it can also be considered as a signal that the channel is at risk, thus triggering the fuse. Switch to a pre-set backup channel for communication: as soon as the monitoring system detects that any one or more of the above fuse conditions is met, it will immediately start the emergency mechanism. The system will automatically stop using the one-way data channel that is currently problematic, and seamlessly switch to another communication method or path that has been prepared in advance, i.e. "pre-set backup channel". This backup channel can be another short message service provider, a satellite communication-based link, a dedicated radio frequency, or any other reliable communication method that has been pre-planned and tested. The purpose of switching is to ensure that even if the main channel fails, the dangerous information can still be sent to the vehicle terminal in a timely and reliable manner through the backup channel, ensuring the continuity of railway safety monitoring.

[0049] In step S30, comprising: Step S304: encapsulate the dangerous information into early warning information with a length of information adapting to the length of short message by using TLV triple protocol.

[0050] It should be noted that TLV represents "Type, Length, Value", which is a common data encapsulation format. It can be imagined as a standard "label" for information.

[0051] Step S305: send the encapsulated early warning information to the vehicle terminal in the form of early warning short message through the short message gateway.

[0052] It should be understood that the information encapsulated by the TLV format and ensured to be of appropriate length has now become a structured, ready-to-send "warning information".

[0053] It should be noted that the original, possibly chaotic dangerous information is first packaged and arranged in a standardized TLV format, and the size is controlled to meet the requirements of the short message; then, through a special short message gateway, the formatted information is sent to the receiving device on the train as a short message. This method not only ensures the standardization and readability of information transmission, but also makes use of the widely existing and relatively reliable communication method of short message.

[0054] Before step S305, it also includes: Step S306: For each of the warning short messages, the warning short messages are de-duplicated by timestamp.

[0055] It should be understood that during communication, the same important warning information may sometimes be sent repeatedly due to network delay, device restart, etc. If the vehicle-mounted terminal receives multiple identical information, not only will it cause interference, but it may also be mistaken for a new, more urgent alarm. De-duplication is to avoid this situation. Each warning short message is stamped with a timestamp when it is generated, recording the exact time it was created or ready to be sent. The system checks the warning short messages to be sent. It uses the timestamp information to compare with the previously sent short messages. If it finds that the short message currently ready to be sent is the same as the content (or core identification information) of a previously sent short message, and the timestamp is also very close (within an acceptable error range), the system will determine that it is a duplicate information and will be discarded or not sent again. This ensures that the same content of the warning information is only treated and sent as a new information within a short period of time.

[0056] Step S307: Continuously send the de-duplicated warning short message to the vehicle-mounted terminal at least three times within a preset time interval.

[0057] It should be noted that the preset time interval is a pre-set time period, such as a few seconds or tens of seconds. Within this time period, the system will send a specific warning information. For the warning short message that has been de-duplicated and confirmed to be "new", the system will not send it only once, but will continuously and repeatedly send it at least three times within the preset time interval. For example, the second time is sent a few seconds after the first time, and the third time is sent a few seconds after the second time.

[0058] After step S305, it also includes: Step S308: Extract the warning location information in the warning short message.

[0059] It should be understood that each early warning short message usually contains a key geographic coordinate or location description, i.e. early warning location information. This represents the specific location of the dangerous event, such as a certain kilometer marker, coordinate point or area. After receiving the short message, the vehicle terminal will first parse the content of the short message and extract the early warning location information from it.

[0060] Step S309: Compare the early warning location information with the current location of the vehicle terminal.

[0061] It should be noted that the vehicle terminal itself usually also has positioning function (such as through GPS, Beidou, etc. satellite positioning system) and can know its own geographic location in real time, i.e. current location. The system will compare the early warning location information just extracted with the real-time location of the vehicle terminal itself. This usually involves calculating the distance between the two or determining whether the two are within a certain safety distance range.

[0062] Step S310: When the current location of the vehicle terminal is less than a preset value from the early warning location in the early warning location information, the early warning information is visually presented through the terminal display layer.

[0063] It should be understood that the preset value is a pre-set safety distance threshold, such as a few hundred meters or a kilometer. This value represents how close the distance needs to be to pay special attention to the early warning. The system will determine whether the calculated distance between the current location of the vehicle terminal and the early warning location is less than the preset value. If the result is yes (i.e. the distance is less than the preset value), it means that the early warning information is directly related to the train currently running, and the driver needs to know immediately and needs to take action. At this time, the vehicle terminal will display this early warning information through its screen and other display layers (terminal display layer) in a conspicuous and easy-to-understand way (such as icons, words, sound prompts, etc.) so that the driver can intuitively see that the danger is near.

[0064] In this embodiment, the characteristics of one-way transmission ensure that in emergency situations, critical warning information will not be blocked or delayed by any response of the vehicle terminal, maximizing the safety of driving. Through real-time monitoring and automatic switching based on specific conditions, the system can quickly enable the backup scheme when the main communication path fails, minimizing the safety risks that may arise from communication interruptions. The TLV packaging method not only ensures the normativity and readability of information transmission, but also takes advantage of the widely available and relatively reliable communication method of SMS. By timestamp deduplication, invalid repeated sending is avoided; then, the valid new information is repeatedly sent multiple times within a short period of time, overcoming network instability factors and ensuring that the driver can receive critical driving safety prompts. This process realizes intelligent filtering and accurate prompting of early warning information. It does not simply display all received warnings to the driver, but only presents those truly close to the train and posing a threat to the current driving safety to the driver through visual (or other sensory) means, thereby helping the driver focus on the most urgent safety issues and improving the effectiveness and practicality of the warning.

[0065] It should be noted that the above examples are only for understanding the present application and do not constitute a limitation on the real-time early warning method for intelligent high-speed rail security, and more forms of simple changes based on this technical concept are within the scope of protection of the present application.

[0066] The present application also provides a real-time early warning device for intelligent high-speed rail security, which is described in detail in Figure 4 , the real-time early warning device for intelligent high-speed rail security comprises: an information collection module 10 for collecting dangerous information within a predetermined range of the railway; an information processing module 20 for transmitting the collected dangerous information to an edge computing node for processing; an information transmission module 30 for unidirectionally sending the processed dangerous information to a vehicle terminal in the form of an SMS, wherein the unidirectional sending prohibits the vehicle terminal from responding or feeding back through the same SMS channel.

[0067] Optionally, the information processing module 20 is further configured to obtain a device hardware fingerprint in the dangerous information; perform trusted data source verification on the dangerous information according to the device hardware fingerprint; and when the dangerous information passes the trusted data source verification, add a signature to the dangerous information using a dispatcher private key.

[0069] Optionally, the information transmission module 30 is further configured to monitor the state of the one-way data channel; when it is monitored that the one-way data channel reaches a preset channel fuse condition, switch to a preset backup channel for communication; wherein the preset channel fuse condition includes: the number of consecutive failures of the one-way data channel to send data reaches a preset threshold, the signal strength is lower than a preset threshold value, and / or the positioning information loss time exceeds a threshold value.

[0070] Optionally, the information transmission module 30 is further configured to encapsulate the danger information into early warning information with a length of the information adapted to the length of the short message by using a TLV triple protocol; and send the encapsulated early warning information to the vehicle terminal in the form of early warning short message through a short message gateway.

[0071] Optionally, the information transmission module 30 is further configured to extract early warning position information in the early warning short message; compare the early warning position information with the current position of the vehicle terminal; and when the current position of the vehicle terminal is less than a preset value from the early warning position in the early warning position information, visually present the early warning information through a terminal display layer.

[0072] Optionally, the information transmission module 30 is further configured to, for each of the early warning short messages, perform a deduplication processing on the early warning short message through a timestamp; and send the deduplicated early warning short message to the vehicle terminal at least three times continuously within a preset time interval.
