Description

Technical Field

[0001] The present application relates to the field of emergency communication control technology, and in particular to a photoelectrically coupled emergency telephone control method, system, device and medium. Background Art

[0002] As railway construction continues to advance, the demand for secure communications is growing. Especially in emergencies like extreme power outages or damaged wireless communication networks, ensuring smooth communications for critical infrastructure and disaster-stricken areas is paramount. Consequently, the need for emergency communication systems along railway lines has emerged. These systems not only address information communication barriers caused by both natural and human factors, but also enable rapid deployment in remote areas or during temporary events, significantly enhancing communication capabilities in these challenging circumstances.

[0003] Among existing emergency communication solutions, one approach utilizes traditional radio wave communication equipment. This type of equipment relies on stable radio signals and works well in open areas, making it widely used for daily communications and general emergency response scenarios. Another common approach is conventional wired telephone systems, which rely on fixed line infrastructure for communication and maintain relatively stable call quality within a certain area, making them suitable for communications in relatively concentrated locations. Each of these approaches has achieved some success in their respective application scenarios and has played a significant role in ensuring emergency communications.

[0004] However, existing technologies have significant drawbacks. Traditional radio wave communication equipment is susceptible to interference from the natural environment and geographical conditions, resulting in unstable signals and, in particular, poor communication quality in inclement weather. Conventional wired telephone systems rely on fixed and fragile lines. In the event of a natural disaster or external damage, these lines can be easily damaged, leading to communication interruptions and impacting the continuity and stability of communications. This makes it difficult to ensure timely communication along railway lines and in remote areas during emergencies. Summary of the Invention

[0005] The first purpose of this application is to provide a photoelectrically coupled emergency telephone control method, which can plan the main communication path of the emergency telephone in advance before a disaster occurs, reduce the occurrence of communication interruptions, and improve the continuity and stability of communication.

[0006] In the first aspect, the present application provides a photoelectric coupling emergency telephone control method, which adopts the following technical solution:

[0007] A photoelectrically coupled emergency telephone control method, comprising:

[0008] Obtain disaster information at sites where several fiber-optic telephones are located and generate a heat map of the disaster probability distribution;

[0009] Based on the disaster probability distribution heat map, obtaining a site safety level corresponding to the disaster type;

[0010] Obtain the power stability and optical link loss status of fiber optic telephone communication nodes in real time and generate node health assessment results;

[0011] According to the predicted disaster type, obtain the node site security level and health assessment results of the sites where several fiber optic telephones are located, dynamically adjust the node composition and topology structure of the main path, and plan the main path;

[0012] A backup path is synchronously preconfigured, wherein nodes of the backup path are distributed at a backup fiber optic telephone site different from that of the primary path.

[0013] By adopting the above technical solution, the heat map generated according to the probability of disasters occurring at each site can determine the site safety level and clarify the safety status of each site. Real-time acquisition of the power supply stability and optical link loss status of the communication node and generation of health assessment results can grasp the safety level of the fiber optic telephone node. Dynamic adjustment of the main path node composition and topology structure based on the disaster type combined with the site safety level and health assessment results helps to plan a suitable main path. Planning the main communication path before a disaster occurs can reduce the occurrence of communication interruptions and improve the continuity and stability of communication. At the same time, pre-configuring backup paths can enhance the reliability and emergency response capabilities of the communication system and ensure smooth communication in extreme environments or emergencies.

[0014] In a preferred example, the present application may be further configured as follows: the step of obtaining disaster conditions at sites where a plurality of fiber optic telephones are located and generating a disaster probability distribution heat map includes:

[0015] Based on the disaster type, diffusion direction, and rate parameters of historical disaster data, calculate and obtain the historical disaster impact range centered on the site where the fiber optic phone is located;

[0016] Obtain the historical disaster impact range and disaster probability of all fiber-optic telephone sites along the railway line, and form a spatially continuous disaster probability distribution heat map based on geographical location;

[0017] Dynamically update the disaster probability distribution heat map based on real-time disaster changes.

[0018] By adopting the above technical solution, the historical disaster impact range centered on the site where the fiber optic telephone is located can clearly define the area affected by historical disasters at each site, and then spread the historical disaster impact area to all sites where fiber optic telephones are located along the railway, forming a spatially continuous disaster probability distribution heat map, which helps to fully understand the disaster probability situation of each site along the line and dynamically update the heat map in real time, so that disaster assessment can be dynamically adjusted according to actual conditions, providing accurate and reliable disaster information basis for subsequent planning of emergency telephone main routes and backup routes.

[0019] In a preferred example, the present application may be further configured as follows: the step of obtaining the power supply stability and optical link loss status of the fiber optic telephone communication node in real time and generating a node health assessment result includes:

[0020] Obtain the optical fiber end face reflectivity and optical power attenuation based on photoelectric coupling measurement;

[0021] Dynamically adjust the optical power attenuation threshold range based on the real-time meteorological conditions of each fiber optic telephone site;

[0022] Based on the comparison results of the reflectivity and the dynamic threshold, an optical link health score of each fiber optic telephone node is generated.

[0023] By adopting the above technical solution, a preliminary evaluation of the fiber optic phone itself is performed based on the optical fiber end face reflectivity and optical power attenuation measured by photoelectric coupling. Combined with real-time meteorological conditions, the optical power attenuation threshold range is dynamically adjusted to comprehensively generate an optical link health score, which can more accurately and in real time evaluate the health status of the fiber optic phone communication node.

[0024] In a preferred example, the present application may be further configured as follows: the steps of obtaining node site security levels and health assessment results of sites where multiple fiber optic telephones are located based on the predicted disaster type, dynamically adjusting the node composition and topology of the primary path, and planning the primary path include:

[0025] According to the predicted disaster type, a topology structure constructed based on fiber optic telephone communication nodes with node health assessment results greater than the health standard value and site security level greater than the safety standard value is planned as the main path, and the link direction of the main path is planned to be orthogonal to the disaster spread direction.

[0026] By adopting the above technical solutions, the communication security and stability of the main path can be improved when a disaster occurs, ensuring smooth communication at critical moments.

[0027] In a preferred example, the present application may be further configured as follows: the steps of obtaining node site security levels and health assessment results of sites where multiple fiber optic telephones are located based on the predicted disaster type, dynamically adjusting the node composition and topology of the primary path, and planning the primary path include:

[0028] When the node health assessment result of a fiber optic phone and the weighted score of several site security levels exceed the preset risk threshold, the site where the fiber optic phone is located is set as a risk hotspot;

[0029] Screen other fiber optic telephone sites along the railway line except for the risk hotspots, and give priority to reconstructing the topology structure of the optoelectronic coupling interface closest to the fiber optic telephone site.

[0030] By adopting the above technical solution, high-risk spatial overlapping areas are identified and set as risk hot spots to prevent the main path from passing through these areas. At the same time, the optoelectronic coupling interface of the nearest fiber optic telephone sites in non-risk hot spots along the railway is preferentially selected to reconstruct the main path topology structure, thereby improving the safety and effectiveness of the main path planning and ensuring smooth communication in emergency situations.

[0031] In a preferred example, the present application may be further configured as follows: the step of synchronously preconfiguring a backup path, wherein nodes of the backup path are distributed at a backup fiber optic telephone site different from that of the primary path, includes:

[0032] Based on the distribution of buildings with fiber-optic telephone sites within the disaster-affected area along the railway, the risk level of several building areas is dynamically divided under the influence of each disaster type;

[0033] According to the main disaster types occurring at the sites where the fiber optic telephones are located, the key nodes of the backup path are divided into backup fiber optic telephones located in building areas that are different from the main path and whose risk levels are within a safe range, and the backup path is pre-configured.

[0034] By adopting the above technical solution, the risk level of building areas can be dynamically divided to adapt to disaster changes in a timely manner. Furthermore, based on the main disaster type of the site, the key nodes of the backup path are divided into backup fiber optic telephones in building areas that are different from the main path and have a safe risk level for pre-configuration, thereby improving the effectiveness and safety of the backup path in the event of a disaster, and improving the reliability and communication guarantee capabilities of the fiber optic telephones.

[0035] In a preferred example, the present application may be further configured as follows: after the step of synchronously preconfiguring a backup path, wherein nodes of the backup path are distributed at backup fiber telephone sites different from those of the primary path, the step further includes:

[0036] When the security level of a site on the primary path node is lower than the security standard value or the optical link loss exceeds the benchmark value, the communication traffic is automatically triggered to migrate to the backup path.

[0037] By adopting the above technical solution, when the main path does not meet the requirements of stable and secure communication, the communication traffic is automatically triggered to migrate to the backup path, so that emergency telephone communications can remain smooth and stable even in disaster situations.

[0038] In a second aspect, the present application provides a photoelectrically coupled emergency telephone control system, which adopts the following technical solution:

[0061] The following is combined with Figure 1-9 This application is described in further detail.

[0062] It should be noted that all actions of obtaining data or information or data in this application are carried out in compliance with the relevant data protection laws and policies of the country where they are located and with the authorization of the corresponding users.

[0063] refer to Figure 1 , a photoelectrically coupled emergency telephone control method, specifically comprising:

[0064] S1. Obtain disaster conditions at sites where several fiber optic telephones are located and generate a disaster probability distribution heat map.

[0065] Specifically, the existing meteorological and environmental monitoring system is linked to obtain and integrate historical disaster records and real-time monitoring data. Geographic Information System (GIS) tools are used to perform spatial analysis of the sites where fiber optic telephones are located, calculate the probability of disasters at each site, and generate a visual heat map in which the color gradient indicates the level of risk. This provides an intuitive prediction of disaster risks, helps identify sites in high-risk areas in advance, and lays the foundation for subsequent safety assessments and route planning, thereby reducing the risk of communication interruptions caused by sudden disasters.

[0066] S2. Based on the disaster probability distribution heat map, obtain the site safety level corresponding to the disaster type.

[0067] Specifically, based on a disaster probability distribution heat map, the system applies preset risk thresholds and disaster classification models, such as distinguishing the degree of damage to fiber-optic telephones from earthquakes and floods. It automatically assigns each site a high, medium, or low risk security level, while also generating a structured security report. In this embodiment, the preset risk threshold is 70%. Sites with a disaster probability exceeding the threshold are designated as high-risk sites. This quantifies site security and provides an objective basis for communication path selection, prioritizing the avoidance of high-risk sites when planning primary routes and enhancing the network's overall disaster resilience.

[0068] S3. Obtain the power supply stability and optical link loss status of the fiber optic telephone communication node in real time and generate a node health assessment result.

[0069] Specifically, by deploying a sensor network to collect power parameters and optical link indicators of fiber optic telephone nodes in real time, in this embodiment, the power parameters use voltage fluctuations as a reference basis, and the optical link indicators use loss values ​​as a reference basis. The node health is evaluated by a weighted scoring method, and the health report is dynamically updated to monitor the node reliability in real time, detect potential fault points early, such as unstable power supply or link degradation, support preventive maintenance, and reduce the probability of communication interruption.

[0070] S4. According to the predicted disaster type, obtain the node site security level and health assessment results of the sites where several fiber optic telephones are located, dynamically adjust the node composition and topology structure of the main path, and plan the main path.

[0071] Specifically, by associating the existing meteorological and environmental monitoring system to predict disaster types, combining the site security level and node health assessment results, based on the graph theory model, the fiber optic network is abstracted into a weighted node graph, and an improved shortest path algorithm is used to recalculate the connection relationship between nodes. Low-risk and healthy nodes are prioritized to form a new topology, while optimizing the number of hops and path redundancy, and then generating a pre-disaster optimized main communication path plan to actively avoid risk nodes, so that the main path has high resilience and low interruption rate before the disaster occurs, thereby improving communication continuity.

[0072] S5. Synchronously preconfigure a backup path, wherein nodes of the backup path are distributed at a backup optical fiber telephone site different from that of the primary path.

[0073] Specifically, while planning the primary path, a backup fiber optic telephone site is selected, the node topology of the backup path is predefined, and the configuration parameters are stored for rapid switching. A redundant backup mechanism is established, and when the primary path is affected by a disaster, it can seamlessly switch to the backup path, maximizing the stability and continuity of communication services.

[0074] refer to Figure 2 Furthermore, in one embodiment, step S1 is further divided into the following sub-steps:

[0075] S10. Calculate and obtain the historical disaster impact range centered on the site where the fiber optic telephone is located based on the disaster type, diffusion direction, and rate parameters of the historical disaster data.

[0076] Specifically, the historical disaster impact range centered on the site where the fiber-optic telephone is located can clearly identify the areas affected by historical disasters at each site. By analyzing historical disaster data, such as earthquake epicenter locations and flood inundation trajectories, the direction and rate of disaster spread are analyzed. Combined with historical disaster boundary data, GIS buffer analysis tools are used to generate dynamic buffer zones along the disaster spread vector. This allows the historical disaster impact radius to be determined, quantifying the site's exposure to specific disaster types. This allows the precise location of the site's historical disaster impact range, providing a spatial basis for disaster probability distribution heat maps and assisting in the identification of disaster-risk sites.

[0077] S11. Obtain the historical disaster impact range and disaster probability of all fiber optic telephone sites along the railway line, and form a spatially continuous disaster probability distribution heat map based on geographical location.

[0078] Specifically, based on the historical disaster probability data of all stations along the railway, the spatial interpolation algorithm of the geographic information system (GIS) is used to convert the discrete station probabilities into a continuous surface, generating a disaster probability distribution heat map covering the entire railway area, in which the color depth intuitively reflects the risk level.

[0079] S12. Dynamically update the disaster probability distribution heat map based on real-time disaster changes.

[0080] Specifically, the real-time disaster monitoring data stream is accessed from the existing meteorological environment monitoring system, and the historical probability value is corrected through the dynamic weight model to drive the periodic or event-triggered update of the heat map to ensure the timeliness of disaster risk prediction, so that path planning can respond to sudden changes in disaster conditions, and try to avoid decision-making bias caused by reliance on outdated information. It provides accurate and reliable disaster information basis for the subsequent planning of emergency telephone main and backup paths, and improves the accuracy of emergency communication preparation.

[0081] In addition, reference Figure 3 Furthermore, in one embodiment, step S3 is further divided into the following sub-steps:

[0082] S30: Obtaining the optical fiber end face reflectivity and optical power attenuation based on photoelectric coupling measurement.

[0083] Specifically, a test light pulse is emitted to the optical fiber end face through a photoelectric coupling measuring device to capture the reflected light intensity and the transmission light power attenuation value in real time. The signal processing unit converts the reflection loss and attenuation coefficient parameters into standard units, thereby realizing millisecond-level monitoring of the physical state of the optical fiber. The potential fiber break risk is accurately identified through reflection anomalies and excessive attenuation, providing a more accurate physical layer basis for link health assessment.

[0084] S31. Dynamically adjust the optical power attenuation threshold range based on the real-time meteorological conditions of the site where each fiber optic telephone is located.

[0085] Specifically, the system integrates real-time meteorological data from fiber optic telephone sites acquired by existing meteorological and environmental monitoring systems, invokes a pre-trained environmental attenuation compensation model, and dynamically adjusts the appropriate threshold range for optical power attenuation. This reduces the impact of environmental interference on monitoring results, minimizes misjudgments due to weather fluctuations, and improves the environmental adaptability of the health score. For example, when high temperatures increase fiber bending loss, the upper threshold limit needs to be automatically adjusted upwards.

[0086] S32. Generate an optical link health score for each fiber optic telephone node based on a comparison result of the reflectivity and the dynamic threshold.

[0087] Specifically, the measured reflectivity is compared with the dynamic optical attenuation threshold. When there is a sudden increase in reflectivity or the attenuation exceeds the threshold, a weighted scoring rule is used to generate an optical link health score, thereby converting physical parameters into actionable fault warning signals, quickly locating vulnerable nodes, and supporting active obstacle avoidance decisions on communication paths.

[0088] In addition, reference Figure 4 Furthermore, in one embodiment, step S4 is further divided into the following sub-steps:

[0089] S40. Based on the predicted disaster type, a topology structure constructed based on fiber optic telephone communication nodes whose node health assessment results are greater than the health standard value and whose site security levels are greater than the safety standard value is planned as the main path, and the link direction of the main path is planned to be orthogonal to the disaster diffusion direction.

[0090] Specifically, a spatial path planning algorithm is used to enforce that the main path links run perpendicular to the primary direction of disaster spread. For example, if floodwaters spread from west to east, north-south links are designed, and the node connection sequence is optimized to minimize the number of path hops. This orthogonal link design minimizes the possibility of disasters destroying adjacent nodes in the direction of spread, reducing the risk of overall path disruption and ensuring smooth communication during critical emergencies.

[0091] In addition, reference Figure 5 Furthermore, in one embodiment, step S40 is further divided into the following sub-steps:

[0092] S400: When a node health assessment result of a fiber optic phone and a weighted score of several site security levels exceed a preset risk threshold, set the site where the fiber optic phone is located as a risk hotspot.

[0093] Specifically, based on the real-time node health score and site security level, a weighted comprehensive risk value is calculated for each site. In this embodiment, the node health score weight is set to 0.6 and the site security level weight is set to 0.4. When the weighted value exceeds the preset risk threshold, the site is marked as a point-like risk hot zone and added to the avoidance list, providing a clear node-level obstacle avoidance target for the main path planning, eliminating the vulnerable points that double the probability of failure from the source.

[0094] S401. Screen other fiber optic telephone sites along the railway line except for risk hot spots, and give priority to reconstructing the topology structure of the optoelectronic coupling interface closest to the fiber optic telephone site.

[0095] Specifically, after eliminating all risk hotspot sites, a nearest neighbor analysis algorithm is used to screen the remaining sites. Nodes with the closest physical proximity and available optocoupler interfaces are prioritized for direct connection. When reconstructing the topology, links are simultaneously constrained to align perpendicularly with the primary direction of disaster spread. Minimizing distance ensures low-latency communication, while the orthogonal topology design prevents cascading failures of multiple nodes along the direction of disaster spread, improving the primary path's survivability during disasters and ultimately enhancing communication security in emergency situations.

[0096] In addition, reference Figure 6 Furthermore, in one embodiment, step S5 is further divided into the following sub-steps:

[0097] S50: Based on the main disaster types occurring at the site where the fiber optic telephone is located, key nodes of the backup path are divided into backup fiber optic telephones located in building areas that are different from the primary path and have risk levels within a safe range, and the backup path is pre-configured.

[0098] Specifically, based on the disaster type distribution of the main path sites, such as frequent floods in Area A and high-risk earthquakes in Area B, the backup fiber optic telephone nodes located in building protection and with risk levels within the safety threshold are selected to pre-configure the backup path topology, so that the backup path and the main path have no common failure points. When a regional disaster destroys the main path, the backup path can immediately take over the communication and realize seamless disaster recovery switching.

[0099] In addition, when screening spare fiber-optic phones, priority should be given to fiber-optic phones with dual power supplies consisting of mains power and power banks to avoid communication interruptions of spare fiber-optic phones as much as possible and improve the reliability and communication guarantee capabilities of fiber-optic phones.

[0100] In addition, reference Figure 7 Furthermore, in one embodiment, after step S5, a step S51 is added:

[0101] S51. When the security level of a site on the primary path node is lower than the security standard value or the optical link loss exceeds the reference value, communication traffic is automatically triggered to migrate to the backup path.

[0102] Specifically, the site security level and optical link loss value of the main path node are monitored in real time. When any node triggers the above conditions, the communication service is automatically switched to the pre-configured backup path through the preset traffic migration strategy. The switching process prioritizes low latency for voice services, realizing active defensive switching before disasters, and trying to avoid communication interruptions due to worsening node risks, so as to keep calls smooth and stable in the event of a disaster.

[0103] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.

[0104] The embodiment of the present application also provides a photoelectrically coupled emergency telephone control system, which corresponds one-to-one to the photoelectrically coupled emergency telephone control method in the embodiment.

The functional modules are described in detail as follows:
