Description

Technical Field

[0001] The present invention relates to the technical field of emergency communication and disaster warning, and in particular to a wake-up and response method based on the linkage of Beidou short message and emergency broadcast. Background Art

[0002] With the frequent occurrence of catastrophic events such as natural disasters and public emergencies, how to promptly and effectively transmit early warning information to people in the disaster-stricken areas and guide them to take corresponding emergency response measures has become an important issue that needs to be urgently addressed in the field of emergency management.

[0003] Traditional emergency warning methods, such as information release through radio, television, and text messages, can provide certain warning effects in some cases, but they have problems such as slow transmission speed, limited coverage, and untimely response. Especially when a disaster occurs, due to power outages and damage to communication infrastructure, traditional communication means often cannot guarantee the timely transmission of information. To this end, we propose a wake-up and response method based on the linkage of Beidou short messages and emergency broadcasts. Summary of the Invention

[0004] The purpose of the present invention is to provide a wake-up and response method based on the linkage of Beidou short message and emergency broadcast to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solution: a wake-up and response method based on the linkage of Beidou short message and emergency broadcast, comprising the following steps:

[0006] Step 1: Generate warning information through the emergency command center and send it to the warning terminal through the Beidou short message communication module;

[0007] Step 2: After the terminal receives the warning information, the display screen shows the warning content and triggers the buzzer alarm. The terminal responsible person needs to confirm the response within the predetermined time;

[0008] Step 3: If the terminal does not confirm the response within the predetermined time, the warning information will be broadcasted in a specific area through emergency broadcasting;

[0009] Step 4: If the terminal fails to confirm the response again, it will automatically activate the SOS alarm button and start Beidou positioning, and report the real-time location to the back-end management platform. At the same time, the emergency broadcast will continue to broadcast;

[0010] Step 5: The back-end management platform dispatches resources, coordinates rescue forces, tracks each response process, and generates a response chain to support dynamic dispatch of rescue resources and decision support.

[0011] Preferably, the specific steps of step 1 include:

[0012] S1.1. Generate warning information including disaster type, warning level, specific guidance, and response requirements based on disaster type, warning level, and regional characteristics;

[0013] S1.2. The generated warning information is encrypted with the national SM4 encryption method and transmitted to the terminal through the Beidou short message communication module.

[0014] Preferably, the Beidou short message communication module supports the Beidou-3 regional short message service, the single transmission capacity does not exceed 1,000 Chinese characters, the single transmission delay does not exceed 30 seconds, and is compatible with the national secret SM4 algorithm encryption. The Beidou short message communication module can automatically switch between the Beidou link and the public network and emergency broadcast, and the public network takes priority. When there is no signal, it switches to Beidou or emergency broadcast. The Beidou short message module supports two-way communication between the terminal and the emergency broadcast transmitter, so that the terminal positioning information is transmitted back to the emergency command center.

[0015] Preferably, the specific steps of step 2 include:

[0016] S2.1. The terminal receives the warning information, displays the disaster type, warning level, and response instructions on the display screen, and triggers the buzzer and vibration reminder;

[0017] S2.2. The terminal sets a response confirmation time. The user needs to confirm the response by pressing the physical button within the preset time. If the terminal does not respond within the preset time, the system enters the next response stage.

[0018] Preferably, in step 3, if no confirmation response is received from the terminal, the back-end management platform issues an instruction to start the emergency broadcast in the area to broadcast disaster warning information, and the broadcast content includes the disaster type, danger level and evacuation instructions.

[0019] Preferably, the emergency broadcast in step 3 includes FM broadcast, medium wave broadcast and terrestrial digital television. The emergency broadcast supports Beidou short message remote control of the emergency broadcast transmitter. The emergency broadcast integrates multilingual speech synthesis technology and supports emergency broadcasts in Mandarin, dialects, minority languages ​​and sign language videos.

[0020] Preferably, the specific steps of step 4 are:

[0021] Step 4.1: Determine whether the terminal confirms the warning information within the specified response time. If no confirmation feedback is received, the system enters the terminal unresponsive state;

[0022] Step 4.2: Activate the SOS alarm button, and the terminal will emit a strong sound prompt to remind the user that the emergency state has arrived;

[0023] Step 4.3: Use BeiDou satellites for real-time positioning to obtain the terminal's longitude, latitude, timestamp, and positioning accuracy, and dynamically adjust the positioning frequency.

[0024] Step 4.4: Transmit the location information to the backend management platform via Beidou short message;

[0025] Step 4.5: After receiving the positioning information, the back-end management platform displays the real-time location of the terminal on the GIS map;

[0026] Step 4.6: The back-end platform issues instructions to continue disseminating information through the emergency broadcast network. The volume and frequency of the emergency broadcast are automatically adjusted according to the ambient noise.

[0027] Preferably, the specific steps of step 5 include:

[0028] Step 5.1: The back-end management platform aggregates, analyzes and stores all received information;

[0034] Preferably, the communication link between the back-end management platform and the terminal also includes 4G network, 5G network, LoRa network and emergency broadcast network. When a problem is detected in one of the communication links, the back-end management platform switches to other available communication links.

[0035] Technical effects and advantages of the present invention:

[0036] The present invention integrates Beidou short message communication, emergency broadcast, SOS alarm, and positioning tracking technology to form a multi-level, comprehensive disaster warning and response system. The main feature of this system is that through the linkage between the terminal and the emergency broadcast, it can realize the rapid transmission of warning information and forcibly awaken people in the disaster-stricken area. At the same time, combined with Beidou satellite positioning and SOS alarm functions, it ensures that people can obtain timely and effective rescue information and response guidance when a disaster occurs.

BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Figure 1 Schematic diagram of the process of the present invention. DETAILED DESCRIPTION

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] The present invention provides Figure 1 The illustrated method for waking up and responding based on the linkage of Beidou short message and emergency broadcast includes:

[0040] Step 1: Generate warning information through the emergency command center and send it to the warning terminal through the Beidou short message communication module;

[0041] The specific steps of step 1 include:

[0042] S1.1. Generate warning information that includes disaster type, warning level, specific guidance, and response requirements based on disaster type, warning level, and regional characteristics, so as to accurately convey the severity of the disaster, the scope of the risk, and emergency response requirements;

[0043] S1.2. The generated warning information is encrypted with the national secret SM4 and transmitted to the terminal through the Beidou short message communication module; ensuring the confidentiality and security of the warning information, preventing the information from being maliciously tampered with or leaked, and complying with China's Cybersecurity Law and relevant information protection standards; this step transmits the encrypted warning information to the terminal through a reliable Beidou short message communication module, ensuring that when the public network is unavailable or there is a network interruption, the warning information can still be stably transmitted through the Beidou satellite link, ensuring the reliability and timeliness of information transmission when a disaster occurs.

[0044] Among them, the Beidou short message communication module supports the Beidou-3 regional short message service, with a single transmission capacity of no more than 1,000 Chinese characters and a single transmission delay of no more than 30 seconds. It is also compatible with the national secret SM4 algorithm encryption. The Beidou short message communication module can automatically switch between the Beidou link and the public network and emergency broadcast, with the public network taking priority. When there is no signal, it switches to Beidou or emergency broadcast. The Beidou short message module supports two-way communication between the terminal and the emergency broadcast transmitter, so that the terminal positioning information can be transmitted back to the emergency command center.

[0045] Step 2: After the terminal receives the warning information, the display screen shows the warning content and triggers the buzzer alarm. The terminal responsible person needs to confirm the response within the predetermined time;

[0046] The specific steps of step 2 include:

[0047] S2.1. When the terminal receives a warning message, it displays the disaster type, warning level, and response instructions on the display screen, and triggers a buzzer and vibration reminder. These visual reminders provide both auditory and tactile cues, ensuring that they effectively capture the user's attention even in noisy environments or when the user is distracted. Especially in disaster scenarios requiring a rapid response, the buzzer and vibration reminders can promptly alert the user, ensuring that the user is immediately aware of the emergency, regardless of whether they are viewing the screen.

[0048] S2.2. The terminal sets a response confirmation time. The user needs to confirm the response through the physical button within the preset time. If the terminal does not respond within the preset time, the system enters the next response stage; this ensures that the terminal can wait for user feedback within a certain period of time, and sets a reasonable time (such as 30 seconds or 60 seconds) to ensure that the user can respond quickly. Through clear time limits, the system can optimize the timeliness of emergency response and avoid affecting the overall emergency action due to delayed response; the physical button confirmation response mechanism provides a simple and intuitive feedback method. Users do not need to rely on touch screens or complex interface operations, which reduces the complexity of operations and ensures that users can respond quickly in emergency situations.

[0049] Step 3: If the terminal does not confirm the response within the predetermined time, the warning information will be broadcasted in a specific area through emergency broadcasting;

[0050] In step 3, if no confirmation response is received from the terminal, the back-end management platform issues a command to start the emergency broadcast in the area to broadcast disaster warning information. The broadcast content includes the disaster type, danger level, and evacuation instructions. If the terminal does not confirm the response within the predetermined time, the back-end management platform immediately issues a command to start the emergency broadcast. This action ensures that the system can quickly start the second-level warning in the absence of a user response, preventing the delayed dissemination of disaster information. As a broadcasting system, emergency broadcasting has the characteristics of wide coverage and fast transmission speed. It can quickly spread to a large area, ensuring that more people receive warning information in a timely manner. By clearly conveying the disaster type and danger level, the broadcast content can effectively inform the audience of the current danger type (such as floods, earthquakes, storms, etc.) and its severity (such as red warnings, orange warnings, etc.). The accuracy of this information can help the audience quickly judge the severity of the situation and take appropriate response actions in a timely manner.

[0051] Among them, the emergency broadcast in step 3 includes FM radio, medium wave radio and terrestrial digital television. Emergency broadcast supports Beidou short messages to remotely control the emergency broadcast transmitter. Emergency broadcast integrates multilingual speech synthesis technology and supports emergency broadcasts in Mandarin, dialects, minority languages ​​and sign language videos. Emergency broadcast uses multiple modes such as FM radio, medium wave radio and terrestrial digital television for broadcasting, which ensures that the broadcast information can be received by as many people as possible in different environments (such as indoors and outdoors, different network coverage areas, etc.). The design of multi-mode broadcasting solves the problem that a single broadcast method may not be able to cover a specific area or is limited by signal conditions, thereby improving the reliability and comprehensiveness of emergency response; through the linkage of Beidou short messages and the emergency broadcast system, the back-end management platform can remotely control the startup and adjustment of the emergency broadcast transmitter. This remote control function is particularly suitable for disaster scenarios where power outages or on-site personnel cannot reach, ensuring the continuity of information dissemination and broadcasting even when the infrastructure is damaged.

[0052] Step 4: If the terminal fails to confirm the response again, it will automatically activate the SOS alarm button and start Beidou positioning, and report the real-time location to the back-end management platform. At the same time, the emergency broadcast will continue to broadcast;

[0053] Among them, the specific steps of step 4 are:

[0054] Step 4.1: Determine whether the terminal confirms the warning information within the specified response time. If no confirmation feedback is received, the system enters the terminal unresponsive state. When the terminal does not confirm the warning information within the specified time, the system automatically determines it as unresponsive. This judgment mechanism ensures that the system can quickly identify unresponsive terminals and promptly proceed to the next emergency response, avoiding information delays or ineffective waiting.

[0055] Step 4.2: Activate the SOS alarm button. The terminal emits a strong sound prompt to alert the user that the emergency is imminent. Activating the SOS alarm button and emitting a strong sound prompt can quickly arouse the user's attention and make them aware of the current emergency. This design, through sound reminders, helps ensure that the user responds in a timely manner, preventing precious response time from being lost due to negligence or failure to detect the alarm.

[0056] Step 4.3: Use BeiDou satellites for real-time positioning to obtain the terminal's longitude, latitude, timestamp, and positioning accuracy, and dynamically adjust the positioning frequency. The BeiDou satellite system provides high-precision positioning services, accurately obtaining the terminal's longitude, latitude, timestamp, and positioning accuracy. This positioning information can provide accurate geographic location data for subsequent rescue operations, ensuring that rescue forces can quickly locate and implement disaster relief efforts. Dynamically adjusting the positioning frequency based on environmental requirements and changes in user location information helps improve positioning accuracy and efficiency. When frequent positioning updates are not required, the frequency of positioning requests can be reduced, reducing system burden. In emergency situations, the system can increase the frequency of positioning updates to ensure real-time positioning information.

[0057] Step 4.4: Transmit the location information to the backend management platform via Beidou short messages. Using Beidou short message technology, location information can be transmitted to the backend management platform with low latency. This short message communication method is not only reliable and stable, but also ensures smooth information transmission, especially when the public network is unavailable. This ensures that the backend management platform can receive timely location information, providing real-time data for subsequent rescue dispatch.

[0058] Step 4.5: After receiving the positioning information, the backend management platform displays the terminal's real-time location on a GIS map. Using the GIS map, the backend management platform can clearly display the terminal's real-time location on the map, allowing dispatchers to directly see the location of the rescue target. This intuitive visual interface facilitates rapid decision-making and resource scheduling, avoiding misunderstandings caused by text-based information transmission.

[0059] Step 4.6: The back-end platform issues a command to continue disseminating information through the emergency broadcast network. The volume and frequency of the emergency broadcast are automatically adjusted according to the ambient noise. The automatic adjustment function of the emergency broadcast volume and frequency can dynamically change according to the intensity of the ambient noise. In a noisy environment, the volume of the broadcast will automatically increase to ensure that the information is not disturbed. In a quiet environment, the volume remains low to avoid excessive interference to the public. This function ensures that the broadcast information can be effectively disseminated in various environments and that disaster victims can obtain rescue information in a timely manner.

[0060] Step 5: The back-end management platform dispatches resources, coordinates rescue forces, tracks each response process, and generates a response chain to support dynamic dispatch of rescue resources and decision support.

[0061] The specific steps of step 5 include:

[0062] Step 5.1: The back-end management platform aggregates, analyzes, and stores all received information. By aggregating and storing all received data, the back-end management platform can centrally manage information, ensuring that no information is lost and facilitating subsequent analysis and decision-making. All disaster response data will be archived in chronological order for easy query and tracing.

[0063] Step 5.2: The backend platform accesses the resource database to query available resources related to disaster response. By accessing the resource database, the backend platform can quickly query all available resources related to disaster response. The platform can view the availability of each resource in real time to prepare for subsequent dispatch.

[0064] Step 5.3: The back-end management platform uses GIS maps and real-time location information to accurately locate the disaster area and mark the affected people and areas. Utilizing GIS mapping technology and real-time location information, the back-end platform can accurately mark the disaster area and the location of the affected people. This precise positioning can effectively support subsequent rescue operations and ensure that rescue forces can reach key locations in a timely manner.

[0065] Step 5.4: The backend platform records each terminal and rescue response step with a timestamp, forming a response chain. The response chain includes: terminal confirmation response, rescue team arrival time, emergency material dispatch time, and the availability of various resources. By recording the timestamps of each terminal and rescue step, the backend platform can track the detailed information of each rescue process, forming a complete response chain. The response chain not only helps managers understand the progress of each step, but also provides data support for subsequent work summary and improvement.

[0066] Step 5.5: The backend platform coordinates collaboration among different rescue teams based on the current disaster situation and resource availability. Based on the real-time disaster situation and resource availability, the backend platform dynamically adjusts the allocation of rescue forces and optimizes collaboration among rescue teams. The system intelligently analyzes the disaster area and adjusts dispatch strategies in real time to ensure coordinated collaboration among multiple rescue forces.

[0067] Among them, available resources include rescue teams, the location and capacity of shelters and refuges, emergency supplies, and transportation. The back-end management platform allocates available resources based on the proximity to the disaster site, transportation accessibility, and resource priority.

[0068] Among them, the communication links between the back-end management platform and the terminal also include 4G network, 5G network, LoRa network and emergency broadcast network. When a problem is detected in one of the communication links, the back-end management platform switches to other available communication links; the integration of multiple communication links (4G, 5G, LoRa and emergency broadcast network) can automatically switch to other available links when any communication link fails, ensuring continuous and uninterrupted communication. Through redundant design, the system ensures a stable connection in various network environments, greatly improving the reliability and resilience of the communication link.

[0069] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
