Description

Technical Field

[0001] This application relates to the technical field of emergency information transmission and processing, and in particular to an emergency broadcasting method, device, equipment, and storage medium that links cities, counties, towns, and villages. Background Technology

[0002] In the field of emergency information dissemination, radio and television, with their wide coverage and rapid transmission capabilities, have become an important means of disseminating emergency information. Countries such as the United States and Japan have long established mature emergency broadcasting and warning systems, such as the Emergency Alert System (EAS) in the United States and the Emergency Warning and Disaster Warning System (EWBS) in Japan, providing timely emergency alerts to the public. This demonstrates the significant value of emergency broadcasting in ensuring public safety. With societal development, people have increasingly higher demands for the efficiency and accuracy of emergency information dissemination, and emergency broadcasting systems are constantly evolving and improving, playing an increasingly important role in emergency management and public services.

[0003] In practical applications, existing emergency broadcasting systems employ various methods to address the issue of emergency information dissemination. Some regions utilize broadcast television networks to cover specific areas and disseminate emergency information. However, network infrastructure is uneven across different regions. While fiber optic networks may cover administrative villages in some areas, coverage of natural villages is weak. In certain special areas, such as some townships surrounded by waterways, wired network coverage faces difficulties. Regarding information transmission, existing systems primarily rely on a single transmission coverage method. In terms of platform integration and coordination, the connection between emergency broadcasting platforms at different levels and in different regions is not smooth enough, and resource allocation is inefficient. In other aspects of the system, security protection, data storage, and effectiveness monitoring and evaluation typically employ relatively basic methods, which are insufficient to meet the application needs of emergency broadcasting in different scenarios.

[0004] Existing emergency broadcasting systems have numerous shortcomings. Uneven network infrastructure in some areas limits the coverage of emergency broadcasts, failing to ensure timely access to emergency information for the public in all regions. The systems suffer from poor compatibility and interoperability; inefficient integration between emergency broadcasting platforms at different levels and in different regions leads to inefficient resource allocation and hinders unified dispatch and control. The limited transmission methods for emergency information make transmission prone to interruptions in complex environments, failing to guarantee comprehensive and timely delivery of emergency information to the public. Furthermore, deficiencies in security, data storage, and effectiveness monitoring and evaluation make it difficult to meet the diverse application needs of emergency broadcasting in different scenarios. Summary of the Invention

[0010] In a preferred embodiment, this application can be further configured such that: the generation of a hierarchical and classified scheduling scheme based on the level, type, and geographic coordinates of the emergency information, wherein the scheduling scheme includes resource allocation instructions and broadcast priority rules, including: When a red rainstorm warning is received from the meteorological bureau, an emergency evacuation voice broadcast command covering the entire county is automatically generated. When a boundary violation event is detected in a specific camera area, the multi-mode transceiver associated with that camera is triggered to immediately play a preset warning audio.

[0011] By adopting the above technical solutions, the county-level emergency broadcasting platform can generate hierarchical and classified dispatch plans based on the level, type, and geographical coordinates of emergency information. When it receives a red rainstorm warning issued by the meteorological bureau, it can automatically generate emergency evacuation voice broadcast instructions covering the entire county, ensuring that all residents of the county receive evacuation information in a timely manner. When a boundary crossing event is detected in a specific camera area, the multi-mode receiver and amplifier bound to the camera can be triggered to immediately play a preset warning audio, achieving timely warning and emergency response.

[0012] In a preferred embodiment, this application can be further configured such that: the emergency broadcast message is sent to the emergency broadcast terminal in the target area via a primary and backup dual-channel transmission network, wherein the primary and backup dual-channel includes a combination of a wired IP network and a wireless FM broadcast network. The main channel is a wired IP network, and message transmission is carried out through a dedicated network and dedicated line link; When a primary channel interruption is detected, a preset 4G network or terrestrial digital television network is activated as a backup channel to complete message relay transmission.

[0013] By adopting the above technical solution and using a dual-channel transmission network with primary and backup, the primary channel is a wired IP network that transmits messages through a dedicated network and dedicated line link, which can ensure the stable transmission of emergency broadcast messages. When the primary channel is interrupted, the 4G network or terrestrial digital television network is activated as a backup channel to take over the transmission, which can avoid the interruption of message transmission due to the failure of the primary channel and ensure that emergency broadcast messages are sent to the emergency broadcast terminals in the target area in a timely and comprehensive manner.

[0014] In a preferred embodiment, this application can be further configured to: monitor the online status, broadcast success rate, and coverage area heat map data of the emergency broadcast terminal in real time, and generate a statistical report containing timeliness assessment indicators, specifically including: The distribution of terminal online rates in each administrative village is displayed in real time through GIS map services; A timeliness score is calculated based on the difference between the broadcast completion time and the expected response time, and areas with scores below the threshold are marked as areas requiring review.

[0015] By adopting the above technical solution, the county-level emergency broadcasting platform receives and parses emergency information, generates dispatch plans based on the emergency information, and sends emergency broadcast messages through a dual-channel transmission network. It can then use GIS map services to display the distribution of terminal online rates in each administrative village in real time, allowing for a direct understanding of terminal online status. Furthermore, it calculates a timeliness score based on the difference between the broadcast completion time and the expected response time, marking areas with scores below a threshold as areas requiring review. This enables a quantitative assessment of the timeliness of emergency broadcasts and identifies areas requiring review, ensuring the effectiveness of emergency broadcasts.

[0016] The second objective of this invention is achieved through the following technical solution: An emergency broadcasting device linking cities, counties, towns, and villages, comprising: The emergency information acquisition module is used by the county-level emergency broadcasting platform to receive and parse emergency information from the superior emergency broadcasting platform, the local early warning release system, and other departments.

The scheme classification module is used to generate a hierarchical and classified scheduling scheme based on the level, type and geographical coordinates of the emergency information. The scheduling scheme includes resource allocation instructions and broadcast priority rules. The message broadcast module is used to send the emergency broadcast message to the emergency broadcast terminal in the target area through a primary and backup dual-channel transmission network. The primary and backup dual channels include a combination of a wired IP network and a wireless FM broadcast network. The report production module is used to monitor the online status, broadcast success rate, and coverage area heat map data of the emergency broadcast terminal in real time, and generate statistical reports containing timeliness assessment indicators.

[0017] By adopting the above technical solution, emergency information from different sources can be received and analyzed, a reasonable dispatch plan can be generated based on the emergency information, the transmission of emergency broadcast messages can be ensured by using a dual-channel transmission network, the status of emergency broadcast terminals can be monitored in real time and statistical reports containing timeliness evaluation indicators can be generated, and four-level linkage of emergency broadcasts at the city, county, town and village levels can be realized, thereby improving the accuracy, timeliness and reliability of emergency information dissemination and solving problems such as insufficient compatibility and linkage of existing emergency broadcast systems and the single information transmission coverage method.

[0018] The above-mentioned objective three of this application is achieved through the following technical solution: A computer device includes a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the steps of the above-described emergency broadcasting method for city, county, town, and village linkage.

[0019] The fourth objective of this application is achieved through the following technical solution: A computer-readable storage medium storing a computer program that, when executed by a processor, implements the steps of the aforementioned emergency broadcasting method linking cities, counties, towns, and villages.

[0020] In summary, this application includes at least one of the following beneficial technical effects: 1.

Detailed Implementation

[0022] The present application will be further described in detail below with reference to the accompanying drawings.

[0023] In one embodiment, such as Figure 1 As shown, this application discloses an emergency broadcasting method that coordinates city, county, town, and village operations, specifically including the following steps: S10: The county-level emergency broadcasting platform receives and analyzes emergency information from the superior emergency broadcasting platform, the local early warning release system, and other departments. The emergency information includes the emergency level, emergency type, and emergency geographic coordinates.

[0024] Specifically, county-level emergency broadcasting platforms receive emergency information from a wide range of sources, including higher-level emergency broadcasting platforms, local early warning systems, and other relevant departments. Higher-level emergency broadcasting platforms can promptly transmit higher-level emergency instructions and information to the county-level platform, ensuring the authority and comprehensiveness of the information. Local early warning systems focus on issuing warnings for local emergencies and can respond quickly to local disasters or emergencies. Other relevant departments, such as emergency management bureaus and meteorological bureaus, provide professional and targeted information, offering more accurate support for emergency broadcasting.

[0025] Emergency information includes key information such as emergency level, emergency type, and emergency geographic coordinates. The emergency level clarifies the severity of the event, helping the platform to take appropriate response measures based on different levels. The emergency type distinguishes different disasters or emergencies, such as natural disasters and public health emergencies, for categorized handling. The emergency geographic coordinates accurately pinpoint the area where the event occurred, enabling emergency broadcasts to precisely cover the target area.

[0026] Upon receiving emergency information, the platform performs analysis. During this process, the platform converts the information's format and extracts its content, transforming complex information into data that the system can recognize and process. Simultaneously, the platform verifies the authenticity and validity of the information to ensure its reliability. In this way, the county-level emergency broadcasting platform can provide accurate foundational data for subsequent dispatching and broadcasting operations.

[0027] S20: Generate a hierarchical and classified dispatch plan based on the level, type, and geographical coordinates of the emergency information. The dispatch plan includes resource allocation instructions and broadcast priority rules.

[0028] Specifically, the county-level emergency broadcasting platform generates a tiered and categorized dispatch plan based on the level, type, and geographical coordinates of the received emergency information. This dispatch plan generation method is highly flexible and targeted, enabling precise resource allocation and broadcast control according to different situations.

[0029] The platform employs different dispatch strategies for different levels of emergency events. For example, in the event of a particularly serious incident, the platform will immediately activate the highest-level response mechanism, mobilizing emergency broadcasting resources throughout the county for comprehensive coverage. For general-level incidents, resources will be allocated selectively based on the scope and severity of the event to avoid waste.

[0030] In terms of emergency response types, different events require different approaches. For natural disasters, such as earthquakes and floods, the platform emphasizes disseminating evacuation and prevention information; for public health emergencies, such as epidemics, it focuses on disseminating prevention knowledge and policies. This categorization approach improves the effectiveness and relevance of emergency broadcasts.

[0031] Taking geographical coordinates into account makes the scheduling plan more precise. The platform determines the target area to be covered based on the specific location of the event and allocates corresponding resources to that area. Simultaneously, the platform also considers the surrounding areas and extends coverage appropriately to ensure comprehensive information dissemination.

[0032] The scheduling plan includes resource allocation instructions and broadcast priority rules. The resource allocation instructions clarify the tasks and responsibilities of each emergency broadcast terminal, ensuring that resources are allocated rationally to each terminal. The broadcast priority rules specify the broadcast order of different information, ensuring that important information is broadcast first and improving the timeliness of emergency broadcasts.

[0033] S30: Sends emergency broadcast messages to emergency broadcast terminals in the target area through a dual-channel transmission network, which includes a combination of a wired IP network and a wireless FM broadcast network.

[0034] Specifically, in order to ensure that emergency broadcast messages can be accurately and timely sent to emergency broadcast terminals in the target area, the platform adopts a dual-channel transmission network, including a combination of wired IP network and wireless FM broadcast network.

[0035] Wired IP networks, serving as the primary channel, offer advantages such as high transmission speed and stability. Message transmission via dedicated network lines ensures rapid information delivery and accurate reception. Furthermore, wired IP networks enable bidirectional communication, facilitating real-time monitoring and management of terminals by the platform.

[0036] However, in certain special circumstances, such as line damage caused by natural disasters, wired IP networks may experience outages. To address this, the platform has set up a wireless FM broadcast network as a backup channel. The wireless FM broadcast network has the advantages of wide coverage and is not limited by geographical conditions, enabling it to continue providing emergency broadcast services when the wired network is interrupted.

[0037] During transmission, the platform monitors the status of the primary and backup channels in real time. If the primary channel is detected to be interrupted, the platform immediately activates the backup channel to ensure uninterrupted transmission of emergency broadcast messages. Simultaneously, the platform monitors the transmission quality of the backup channel and adjusts transmission parameters promptly to ensure message clarity and accuracy.

[0038] By combining primary and backup dual-channel transmission networks, the platform can effectively improve the reliability and stability of emergency broadcast messages, ensuring that information can be delivered to the public in the target area in a timely and accurate manner in various complex environments.

[0039] S40: Monitor the online status, broadcast success rate, and coverage area heat map data of emergency broadcast terminals in real time, and generate statistical reports including timeliness assessment indicators.

[0040] Specifically, the county-level emergency broadcasting platform will monitor the online status of emergency broadcasting terminals, broadcast success rate, and coverage area heat map data in real time, and generate statistical reports that include timeliness assessment indicators.

[0041] By monitoring the online status of terminals in real time, the platform can promptly detect terminal faults and anomalies and take corresponding measures to repair them. This helps ensure the normal operation of the emergency broadcasting system and improves the system's reliability and stability.

[0042] Monitoring the broadcast success rate reflects the effectiveness of emergency broadcast messages. The platform tracks the percentage of terminals that receive and successfully broadcast messages. By analyzing the broadcast success rate, the platform can identify problems in the transmission process and make timely optimizations and improvements.

[0043] Coverage area heatmap data can intuitively display the coverage range and effectiveness of emergency broadcasts. By analyzing the heatmap data, the platform can understand which areas have good coverage and which areas have coverage blind spots, thus allowing for targeted adjustments to broadcast strategies to improve coverage effectiveness.

[0044] When generating statistical reports, the platform focuses on timeliness assessment indicators. Timeliness is one of the key indicators for emergency broadcasting, directly affecting the public's ability to access and respond to information. The platform calculates the timeliness of information dissemination based on the release time of emergency information and the broadcast time of the terminal, and uses this as an important basis for evaluating system performance.

[0045] By monitoring and evaluating the status of terminals in real time, the platform can continuously optimize the performance of the emergency broadcasting system, improve the effectiveness and efficiency of emergency information dissemination, and provide the public with more timely and accurate emergency services.

[0046] In summary, this city-county-town-village coordinated emergency broadcasting method achieves efficient, accurate, and reliable emergency broadcasting through a series of steps, including receiving and parsing emergency information, generating dispatch plans, transmitting messages, and monitoring terminal status. This method can fully utilize various resources, improve the performance and service quality of the emergency broadcasting system, and provide strong support for responding to various disasters and emergencies.

[0047] In one embodiment, prior to step S10, the emergency broadcasting method linking cities, counties, towns, and villages further includes: S101: Perform address matching verification on the received emergency information through the emergency broadcast adapter, and filter emergency broadcast messages associated with the local area.

[0048] Specifically, emergency broadcast adapters play a crucial role in the address matching and verification phase. These adapters are deployed at relevant stations, such as DTMB and FM transmitters. When emergency information is transmitted from higher-level emergency broadcast platforms, local early warning systems, and other departments, the adapters receive this information in real time. During reception, the adapters utilize their built-in address matching function to compare the geographical coordinates and other address information in the received emergency information with the address range of the local area.

[0049] The emergency broadcast adapter of the DTMB transmitter receives, parses, and responds to emergency broadcast messages sent by the emergency broadcast platform in real time. During this process, it carefully checks the address information in the emergency message to see if it is related to the local area. If the address information matches, it indicates that the emergency message may be related to the local area and will be retained for further processing; if the address information does not match, it indicates that the emergency message is unrelated to the local area and will be filtered out.

[0050] S102: Perform digital signature verification on emergency information that matches the address. Information that fails verification is marked as abnormal and the subsequent processing is terminated.

[0051] Specifically, address matching verification is also performed on the emergency broadcast message adaptation equipment of the FM transmitter. It connects to the county emergency broadcast platform via the dedicated broadcast network and analyzes the address information in the received emergency broadcast messages. Only when the address information is associated with the local area will the message be included in the subsequent processing flow.

[0052] This address matching and verification mechanism can prevent irrelevant emergency information from entering the county-level emergency broadcasting platform, reducing unnecessary processing burdens and improving system efficiency. At the same time, it also ensures that subsequent dispatch plans and broadcast emergency messages are targeted at the local area, improving the relevance and effectiveness of emergency information.

[0053] After address matching verification is completed, emergency broadcast messages associated with the local area are filtered out. These address-matched emergency messages are then digitally signed for verification. Digital signature technology plays a crucial role in the data security protection of the emergency broadcast system. Emergency information, emergency broadcast messages, and transmission dispatch instructions all utilize digital signature technology throughout the entire process to protect their authenticity, integrity, and non-repudiation.

[0054] The digital signature verification process strictly follows relevant standards, such as the "Emergency Broadcast Security Protection Technical Specification for Digital Signatures" (GD / J081-2018) standard. The emergency broadcast adapter uses a pre-set digital signature verification algorithm and key to verify emergency information that has been matched with the address.

[0055] During the verification process, the adapter checks whether the digital signature in the emergency message matches the message content. The digital signature is generated using a specific encryption algorithm and contains the characteristics of the message and the sender's identity information. If the digital signature verification is successful, it means that the emergency message has not been tampered with during transmission and was indeed sent by a legitimate sender. The message is then considered valid and can proceed with further processing.

[0056] If digital signature verification fails, it indicates a potential problem with the emergency message, such as tampering or an illegitimate sender. In this case, the message is marked as abnormal, and subsequent processing is immediately terminated. This effectively prevents false or tampered emergency messages from entering the system, ensuring the security and reliability of the emergency broadcasting system.

[0057] Through this dual verification mechanism—first address matching and then digital signature verification—the county-level emergency broadcasting platform can accurately filter out reliable emergency information relevant to the local area. This not only improves the processing efficiency and targeting of the emergency broadcasting system but also enhances its security and reliability, ensuring that emergency broadcast messages can be promptly and accurately delivered to the public in the target area during emergencies, providing strong protection for the public's life and property. At the same time, this verification mechanism also meets the security requirements of the emergency broadcasting system, satisfies the application needs of emergency broadcasting in different scenarios, and better serves emergency management and public services.

[0058] In one embodiment, in step S20, a hierarchical and classified scheduling scheme is generated based on the level, type, and geographical coordinates of the emergency information. The scheduling scheme includes resource allocation instructions and broadcast priority rules, including: S21: When a red rainstorm warning is received from the meteorological bureau, an emergency evacuation voice broadcast command covering the entire county is automatically generated.

[0059] Specifically, upon receiving a red rainstorm warning from the meteorological bureau, the entire system will quickly and automatically generate emergency evacuation voice broadcast instructions covering the entire county. This process involves the coordinated operation of multiple links. First, the county-level emergency broadcasting platform will maintain close data interaction with the meteorological bureau and other horizontal departments. Once the meteorological bureau issues a red rainstorm warning, the warning information will be transmitted to the county-level emergency broadcasting platform securely and reliably through established interface specifications. This interface follows strict standards to ensure the accuracy and timeliness of information during transmission.

[0060] Upon receiving the early warning information, the county-level emergency broadcasting platform immediately analyzes it. It accurately identifies the warning level as a red rainstorm warning, the most severe level, meaning the entire county may face significant risks of floods, landslides, and other disasters. Based on this, the platform quickly determines, according to pre-set algorithms and rules, that the warning affects the entire county.

[0061] Next, the platform will access the template library within the broadcasting system. This library contains pre-stored voice broadcast templates for different emergency situations. For emergencies like red rainstorm warnings, there is a dedicated emergency evacuation voice broadcast template. The platform will personalize and adjust the template based on the specific content of the warning information, such as the expected rainfall and potentially affected areas. For example, if the warning mentions that certain low-lying areas may be the first to be threatened by flooding, the voice broadcast will specifically remind residents in these areas to evacuate as soon as possible.

[0062] After the voice content is edited, the platform converts it into an audio file. This process utilizes professional speech synthesis technology to ensure the voice is clear, accurate, and easy to understand. At the same time, to guarantee the authority and credibility of the voice, the voice tone may be carefully selected, typically using a calm and serious male or female voice.

[0063] Subsequently, the dispatch and control system will allocate resources and determine broadcast priorities based on the generated emergency evacuation voice broadcast instructions. In terms of resource allocation, the instructions will be assigned to suitable transmission coverage resources. Since coverage of the entire county is required, multiple transmission channels, including wired IP networks and wireless FM broadcast networks, will be fully utilized. For the wired IP network, audio files will be rapidly transmitted to various emergency broadcast terminals via dedicated network links. For the wireless FM broadcast network, the audio files will be modulated to appropriate frequencies for broadcast.

[0064] In terms of broadcast priority, emergency evacuation voice broadcast instructions will be set to the highest priority. This means that if there are other non-emergency broadcast tasks at the same time, the system will prioritize processing this instruction to ensure that residents throughout the county can receive emergency evacuation information as soon as possible. At the same time, to ensure the effectiveness of information transmission, a loop playback method will be used, repeating the emergency evacuation voice message at regular intervals so that more residents can hear it.

[0065] S22: When a boundary crossing event is detected in a specific camera area, the multi-mode receiver / receiver bound to that camera is triggered to immediately play a preset warning audio.

[0066] Specifically, when a boundary violation event is detected in a specific camera area, the system will react quickly, triggering the multi-mode receiver / amplifier associated with that camera to immediately play a preset warning audio. In the video-video linkage pilot area, each pilot is equipped with 10 high-definition boundary violation detection cameras. These cameras monitor the specific area in real time and have high-precision image recognition and analysis capabilities.

[0067] The camera continuously collects image data of the monitored area and transmits this data to the backend analysis system in real time. The analysis system uses advanced computer vision algorithms to identify and judge objects and scenes in the images. When an object enters a pre-defined boundary crossing area, the system quickly detects this change and determines it as a boundary crossing event.

[0068] Once a boundary violation is confirmed, the system immediately sends this information to the dispatch and control system. The dispatch and control system then quickly locates the multi-mode transceiver associated with that camera. The system's database records the binding relationships between each camera and its corresponding multi-mode transceiver, allowing for a quick search to find the appropriate transceiver.

[0069] Then, the dispatch control system will immediately send a command to the multimode receiver to play a preset warning audio. This preset warning audio is set during system initialization and is usually a clear, loud sound with a strong warning effect, such as a sharp alarm or a clear voice prompt, such as "You have entered a danger zone, please leave immediately".

[0070] Upon receiving a command, the multi-mode transceiver responds quickly and begins playing a preset warning audio. Because it supports multiple receiving methods, it ensures stable and reliable command reception and audio playback. Furthermore, the multi-mode transceiver is waterproof and dustproof, adapting to various harsh outdoor environments and guaranteeing normal operation in different weather conditions. The tweeter clearly amplifies the warning audio; its 25W power and 4-8Ω input impedance ensure wide sound range and clarity, allowing those who may cross the line to hear the warning message promptly and avoid potential danger.

[0071] In summary, this emergency broadcasting method, through precise scheduling and efficient execution, can promptly and accurately convey emergency information to residents in relevant areas when facing different types of emergency situations, providing strong support for safeguarding people's lives and property.

[0072] In one embodiment, in step S30, the emergency broadcast message is sent to the emergency broadcast terminal in the target area through a primary and backup dual-channel transmission network. The primary and backup dual-channel network includes a combination of a wired IP network and a wireless FM broadcast network. S31: When the main channel is a wired IP network, message transmission is carried out through dedicated network and dedicated line links.

[0073] Specifically, the main channel uses a wired IP network, and message transmission is conducted via dedicated network lines. Wired IP networks offer significant advantages such as high bandwidth, low latency, and strong stability, providing a solid guarantee for the rapid and accurate transmission of emergency broadcast messages. To ensure transmission reliability, the dedicated network lines employ a redundant design of one primary and one backup, effectively preventing large-scale transmission failures caused by single-point failures. Specifically, the horizontal departmental access lines and the platform's static IP broadband lines both use a rate of 100Mbps / line, while the pilot terminal access lines use a rate of 20Mbps / line, ensuring sufficient bandwidth support for different access points.

[0074] In practice, the county-level emergency broadcasting platform sends the parsed and processed emergency broadcast messages via a dedicated wired IP network link. During this process, the link monitors the message transmission status in real time. If any anomalies are detected, such as packet loss or excessive latency, the system immediately takes appropriate measures to ensure stable message transmission. Furthermore, to further ensure message security, the dedicated network link employs strict access control and data encryption technologies to prevent messages from being stolen or tampered with during transmission.

[0075] S32: When the main channel is detected to be interrupted, a preset 4G network or terrestrial digital television network is started as a backup channel to complete the message relay transmission.

[0076] Specifically, when the main channel is interrupted, the system will quickly activate a pre-set 4G network or terrestrial digital television network as a backup channel to complete the relay transmission of messages. The 4G network features wide coverage and flexible deployment, serving as an important supplementary means in areas where wired two-way networks are unavailable, ensuring that emergency broadcast messages can reach these areas. The terrestrial digital television network, on the other hand, has the advantages of strong signal and high stability, making it the preferred backup link in areas covered by DTMB signals.

[0077] When activating the backup channel, the system first checks the availability of the 4G network or terrestrial digital television network to ensure transmission capability. If the 4G network is available, the system automatically converts the emergency broadcast message into a format suitable for 4G network transmission and sends it to the emergency broadcast terminal in the target area via the 4G network. If the terrestrial digital television network is available, the system deploys an emergency broadcast adapter at the DTMB transmitter station to receive, parse, and respond to emergency broadcast messages issued by the emergency broadcast platform in real time. It generates a terrestrial digital television emergency broadcast index table and content table transport stream, which is then multiplexed and broadcast. This stream, along with the digital television program stream, is transmitted via the backbone network to various transmitter stations. Through DTMB modulation and transmission, terrestrial digital television terminals with emergency broadcast capabilities can achieve automatic wake-up and forced reception.

[0078] To ensure the effective operation of the backup channel, the system also monitors its transmission status in real time. If a problem is detected in the backup channel, the system will promptly attempt to switch to another available backup channel or take other emergency measures, such as restarting the primary channel. Simultaneously, the system will record the usage and related data of the backup channel for subsequent analysis and optimization.

[0079] In addition, to improve the reliability and stability of the entire transmission process, the system regularly tests and maintains the primary and backup dual channels. During testing, various possible fault scenarios are simulated to verify the system's switching and recovery capabilities under different conditions. During maintenance, network equipment and transmission lines are inspected and maintained to promptly identify and resolve potential problems, ensuring that the primary and backup dual channels are always in good operating condition.

[0080] The design and application of this dual-channel transmission network ensures that emergency broadcast messages are delivered promptly and accurately to emergency broadcast terminals in target areas under various complex environments. This effectively avoids information transmission interruptions caused by network failures and provides strong support for emergency management and public services. Simultaneously, this transmission method improves the compatibility and interoperability of the emergency broadcast system, enabling smoother integration between emergency broadcast platforms at different levels and in different regions, achieving efficient resource scheduling and utilization.

[0081] In one embodiment, step S40 involves real-time monitoring of the online status, broadcast success rate, and coverage area heat map data of the emergency broadcast terminal, and generating a statistical report containing timeliness assessment indicators, specifically including: S41: Real-time display of terminal online rate distribution in each administrative village through GIS map service.

[0082] Specifically, the system utilizes GIS services provided by the basic service system to display the real-time distribution of terminal online rates in each administrative village via GIS map services. This service supports offline maps and can display device coordinate information in real time, laying the foundation for displaying the terminal online rate distribution. The system collects online status data from emergency broadcast terminals, which is then fed back to the county-level emergency broadcast platform's effectiveness monitoring and evaluation system. The effectiveness monitoring and evaluation system organizes and analyzes the collected data, calculating the number of online emergency broadcast terminals and the total number of terminals in each administrative village. Then, based on the ratio of online terminals to the total number of terminals, the system calculates the terminal online rate for each administrative village.

[0083] S42: Calculate the timeliness score based on the difference between the broadcast completion time and the expected response time, and mark the areas with scores below the threshold as areas that need to be reviewed.

[0084] Specifically, to clearly display the distribution of online rates on the GIS map, the system links the geographical boundaries of each administrative village with the corresponding terminal online rate data. Different terminal online rates are distinguished by different colors or icons on the GIS map. For example, administrative villages with high online rates may be represented by green icons, those with medium online rates by yellow icons, and those with low online rates by red icons. The map also provides zoom in, zoom out, and drag-and-drop functionality, allowing operators to view detailed information for different areas. Operators can click on the administrative village icon on the map to view the specific number of online terminals, the total number of terminals, and the specific online rate for that village. This intuitive display allows emergency broadcast system administrators to quickly understand the online status of emergency broadcast terminals in each administrative village, promptly identify areas with low online rates, and take appropriate measures, such as checking for equipment malfunctions or network interruptions, to ensure the normal operation of emergency broadcast terminals and guarantee the dissemination of emergency information.

[0085] Secondly, in calculating a timeliness score based on the difference between the broadcast completion time and the expected response time, and marking areas with scores below a threshold as areas requiring review, the effectiveness monitoring and evaluation system records the broadcast completion time of each emergency broadcast message. The expected response time is pre-set when generating the dispatch plan, based on factors such as the level, type, and geographical coordinates of the emergency information. The system compares the broadcast completion time of each emergency broadcast message with its corresponding expected response time and calculates the difference between the two.

[0086] Based on this difference, the system will establish a set of scoring rules to calculate the timeliness score. For example, if the broadcast completion time is within the expected response time, a higher score may be given; if the broadcast completion time exceeds the expected response time by a short period, a medium score may be given; and if the exceedance is significant, a lower score will be given. The system will calculate the average timeliness score for each administrative village based on the timeliness scores of emergency broadcast messages within each administrative village.

[0087] For administrative villages with an average timeliness score below a set threshold, the system will mark them as areas requiring review. These areas will be highlighted on the GIS map with special identifiers, such as flashing red borders or prominent text prompts. Simultaneously, the system will generate a corresponding review report, which will include basic information about the area, the broadcast status of emergency broadcast messages, the timeliness score, and an analysis of potential problems. Emergency broadcast system administrators can use this information to conduct in-depth investigations of the areas requiring review, identify the reasons for the low timeliness score (such as transmission network failures, terminal equipment problems, or unreasonable dispatch plans), and take targeted measures to improve the timeliness of emergency broadcast messages in the area, ensuring that emergency information reaches the public promptly and accurately.

[0088] By implementing these two steps, the operation of the emergency broadcasting terminal can be comprehensively monitored and evaluated, problems in the system can be identified and resolved in a timely manner, thereby improving the reliability of the emergency broadcasting system and the efficiency of emergency information dissemination, and better serving emergency management and public services.
