Description

Technical Field

[0001] This invention relates to the field of emergency communication and public safety technology, and in particular to an emergency broadcasting system and method for wake-up and call-out in extreme environments based on multi-standard and multi-channel fusion. Background Technology

[0002] In the event of sudden natural disasters such as earthquakes, floods, and mudslides, complex geographical areas such as high mountains and canyons are prone to falling into an extreme state of "three disruptions" due to disaster damage: power supply interruption, paralysis of public network communication links, and road traffic blockage. As a result, the affected areas become "communication islands." Traditional emergency broadcasting systems, which rely too heavily on public network infrastructure (such as 2G / 3G / 4G public networks and wired transmission links), completely lose their operational basis under the "three disruptions" conditions, resulting in the inability to deliver "lifesaving information" such as emergency evacuation and rescue guidance to trapped people.

[0003] Looking further, existing emergency broadcasting systems have three major flaws: First, their technical architecture is simplistic, often employing independent wired, wireless, or satellite communication modes without multi-standard channel integration. Failure of any communication link can paralyze the entire system. Second, they lack a feedback loop mechanism, enabling only one-way broadcasting. Command centers cannot monitor the coverage and effectiveness of information delivery in real time, nor can they identify unawakened individuals, leading to inefficient emergency resource allocation and delays in rescue efforts. Third, their equipment relies on external support. Terminals (such as village loudspeakers and mobile phone SMS receivers) depend on external power sources or public network power, making them susceptible to malfunctions due to power outages or network disruptions. Furthermore, their deployment is primarily outdoors, failing to achieve precise "door-to-door" coverage.

[0004] In addition, existing emergency broadcasting systems generally suffer from the problem of "technological silos." The wired, wireless, broadcasting, and video subsystems lack unified business coordination, information cannot be shared, and it is difficult to form a resilient emergency communication network, thus failing to meet the needs of "continuous communication and accurate broadcasting" in extreme environments. Summary of the Invention

[0005] This invention provides an emergency broadcasting system and method for extreme environments based on multi-standard and multi-channel fusion, which solves the pain points of existing technologies through three major components and a closed-loop process.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: The emergency broadcasting system for extreme environments based on multi-standard and multi-channel fusion includes a "wake-up and call-out" base station, a "wake-up and call-out" command host, and a "wake-up and call-out" terminal. The three components construct a decentralized self-organizing communication network through multi-standard and multi-channel communication. The multi-standard and multi-channel communication includes at least two of the following: low-power Internet of Things (IoT), shortwave radio, and BeiDou emergency communication. The system can achieve a closed-loop process of emergency information "release-response-confirmation". Specifically, the command host releases a broadcast command, the base station relays or directly transmits the command to the terminal, the terminal triggers a wake-up function after receiving the command, the public provides confirmation information through the terminal, and the command host or the superior command center receives the feedback and displays the information coverage status.

[0007] In this specification, the "wake-up and response" base station has northward multi-channel communication capability. The northward multi-channel communication includes at least one of Beidou short message communication, 5G public network communication, and medium wave emergency message reception, which is used to receive instructions or report on the situation on site with the superior emergency broadcasting platform.

[0008] In this specification, the "wake-up call" base station also has southbound self-organizing network communication capability. The southbound self-organizing network communication relies on a data transmission shortwave radio module, a low-power IoT module, and an FM broadcast transmission subsystem. It can automatically discover and network with the command host and the terminal to achieve multi-hop routing, and does not affect the basic emergency command capability of the southbound communication network when the base station fails.

[0009] In this specification, the "wake-up and response" command host has a built-in self-organizing network module and a relay module, which can quickly build a local emergency broadcast communication network in the "three-disruption" environment without a central base station. The command host also has a "one-click call" function, which can wake up the terminals in batches and issue emergency commands. At the same time, it can report the feedback information of the terminals to the superior command center.

[0010] In this specification, the "wake-up and response" terminal has a forced wake-up function and an active feedback function; the forced wake-up function is: the terminal triggers a high-decibel sound and light alarm after receiving a specific command; the active feedback function is: the terminal is equipped with a "I have received" physical button, after the user presses the button, the terminal sends a confirmation receipt signal to the self-organizing communication network, and the terminal also supports voice reply feedback.

[0011] In this specification, the “wake-up call” base station, the “wake-up call” command host, and the “wake-up call” terminal all have independent power supply capabilities; among them, the base station and the command host are powered by long-life batteries, and the terminal supports low-power standby mode and has a built-in long-life battery that can work continuously for at least 72 hours in a “three-disruption” environment.

[0012] In this specification, the multi-standard multi-channel also includes at least one of wireless frequency modulation amplitude modulation broadcasting and low-cost 5G RedCap+AIoT wireless communication, and a protocol conversion module and a resource scheduling module are provided between different standard channels to realize dynamic switching and complementary backup of channels.

[0013] An emergency broadcast method for wake-up and call-response in extreme environments based on multi-standard and multi-channel fusion, applied to any of the systems described above, includes the following steps: S1: When the command is issued, the on-site commander sends a broadcast command through the "wake-up and response" command host. The command is transmitted to the "wake-up and response" base station or directly to the "wake-up and response" terminal through multiple standards and channels. S2: Forced wake-up, the terminal is activated after receiving the instruction, triggering a high-decibel sound and light alarm to wake up the public; S3: Information interaction: After being awakened, the public receives emergency information through the terminal and can also respond by voice through the terminal; S4: Feedback collection. When the user presses the "I have received" physical button on the terminal, the terminal sends a confirmation receipt signal, which in turn commands the host to receive the receipt signal and provide a voice reply. S5: Closed loop formation: The superior command center displays the "activated" (called) and "responded" (responded) status of the terminal in real time through the visualization module, forming an information closed loop.

[0014] In this specification, in step S1, the broadcast instructions include pre-recorded voice broadcast instructions and real-time shouting instructions, and the command host has regional response capabilities, which can accurately send instructions to base stations or terminals in the target area.

[0015] In this specification, in step S5, the visualization module is built based on a GIS system and can mark the location and feedback status of each terminal in map form, so that the command personnel can intuitively obtain the coverage and effectiveness of information delivery.

[0016] In summary, the present invention has at least the following beneficial effects: Completely breaks through the limitations of "communication islands": Through the deep integration of multiple standards and channels (low-power IoT, data transmission shortwave radio, Beidou emergency communication, 5GRedCap+AIoT, etc.) and a decentralized self-organizing network architecture, the system can still build mutually backup and complementary communication links in the extreme environment of "three interruptions" without relying on external power or public networks. This fundamentally solves the problem of the complete failure of traditional emergency broadcasting and ensures the continuity and reliability of emergency information transmission.

[0017] The "Wake Up and Response" terminal is equipped with a high-decibel sound and light alarm to force wake up people who are resting or unaware of danger. At the same time, the terminal adopts a portable design for in-home deployment and combines multi-mode independent communication capabilities to ensure that emergency information can be accurately delivered to every household and every trapped person, avoiding life safety risks caused by "information omission".

[0018] Constructing a closed-loop system for precise response: The physical "I have received" button on the terminal and the voice reply function, combined with the real-time situation display in the command center (GIS map marking "called" and "responded"), create a complete closed loop from "release" to "public response" and then to "command center confirmation". Commanders can accurately grasp the information coverage and allocate rescue resources in a targeted manner, completely getting rid of the dilemma of traditional "blind broadcasting" and improving the efficiency of emergency command.

[0019] Enhanced system resilience and adaptability: The complementary design of multi-standard channels, the "self-healing" capability of the self-organizing network (the failure of a certain node does not affect the overall network), and the autonomous power supply function of each component enable the system to adapt to complex geographical and extreme environments such as high mountains and valleys and post-disaster ruins. It has strong anti-interference and anti-damage capabilities and can support the needs of post-disaster emergency broadcasting and command for a long time. Attached Figure Description

[0025] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of the embodiments of the invention. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0026] The following disclosure provides many different implementations or examples for carrying out different structures of the embodiments of the present invention. To simplify the disclosure of the embodiments of the present invention, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the embodiments of the present invention. Furthermore, reference numerals and / or reference letters may be repeated in different examples of the embodiments of the present invention; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various implementations and / or arrangements discussed.

[0027] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0028] like Figure 1 As shown, this embodiment provides an emergency broadcasting system for extreme environments based on multi-standard and multi-channel fusion, including a "wake-up and call" base station, a "wake-up and call" command host, and a "wake-up and call" terminal. The three components construct a decentralized self-organizing communication network through multi-standard and multi-channel communication. The multi-standard and multi-channel communication includes at least two of the following: low-power Internet of Things, data transmission shortwave radio, and Beidou emergency communication. The system can realize a closed-loop process of emergency information "release-response-confirmation". Specifically, the command host releases a broadcast command, the base station relays or directly transmits the command to the terminal, the terminal triggers a wake-up function after receiving the command, the public provides confirmation information through the terminal, and the command host or the superior command center receives the feedback and displays the information coverage status.

[0029] like Figure 2 As shown, the wake-up call base station is a fixed-deployment regional core node. In terms of hardware, it integrates a northward multi-standard communication unit, a southward self-organizing network communication unit, an FM broadcast and directional loudspeaker unit, and an autonomous power supply unit. The four units work together to achieve external interconnection, local coverage, emergency call, and continuous operation during power outages.

[0030] In some embodiments, the "wake-up call" base station has northward multi-channel communication capability, which includes at least one of Beidou short message communication, 5G public network communication, and medium wave emergency message reception, for receiving instructions or reporting on-site conditions with the superior emergency broadcasting platform.

[0031] In some embodiments, the "wake-up call" base station also has southbound self-organizing network communication capability. The southbound self-organizing network communication relies on a data transmission shortwave radio module, a low-power Internet of Things module, and an FM broadcast transmission subsystem. It can automatically discover and network with the command host and the terminal to achieve multi-hop routing, and does not affect the basic emergency command capability of the southbound communication network when the base station fails.

[0032] like Figure 3 As shown, the wake-up call command host is a portable on-site command device that integrates a data transmission shortwave module, a low-power IoT module, a 5G RedCap communication module, a one-click call command management module, and a host power supply module. It can quickly build a local emergency command network without relying on central infrastructure.

[0033] In some embodiments, the "wake-up and response" command host has a built-in self-organizing network module and a relay module, which can quickly build a local emergency broadcast communication network in the "three-disruption" environment without a central base station. The command host also has a "one-click call" function, which can wake up the terminals in batches and issue emergency commands, and can report the feedback information of the terminals to the superior command center.

[0034] like Figure 4 As shown, the wake-up terminal is a portable, standalone device deployed in a home. Its hardware integrates a data transmission shortwave module, a low-power IoT module, an FM radio receiver module, a high-decibel sound and light alarm module (not shown in the figure), a one-button wake-up physical button, and a terminal power supply module. It can independently complete signal reception, forced wake-up, and confirmation feedback in a network-free environment.

[0035] In some embodiments, the "wake-up call" terminal has a forced wake-up function and an active feedback function; the forced wake-up function is: the terminal triggers a high-decibel sound and light alarm after receiving a specific instruction; the active feedback function is: the terminal is equipped with a "I have received" physical button, and after the user presses the button, the terminal sends a confirmation receipt signal to the self-organizing communication network, and the terminal also supports voice reply feedback.

[0036] In some embodiments, the "wake-up call" base station, the "wake-up call" command host, and the "wake-up call" terminal all have independent power supply capabilities; wherein, the base station and the command host are powered by long-life batteries, the terminal supports low-power standby mode, and has a built-in long-life battery that can work continuously for at least 72 hours in a "three-disruption" environment.

[0037] In some embodiments, the multi-standard multi-channel also includes at least one of wireless frequency modulation amplitude modulation broadcasting and low-cost 5G RedCap+AIoT wireless communication, and a protocol conversion module and a resource scheduling module are provided between different standard channels to realize dynamic switching and complementary backup of channels.

[0038] An emergency broadcast method for wake-up and call-response in extreme environments based on multi-standard and multi-channel fusion, applied to any of the systems described above, includes the following steps: S1: When the command is issued, the on-site commander sends a broadcast command through the "wake-up and response" command host. The command is transmitted to the "wake-up and response" base station or directly to the "wake-up and response" terminal through multiple standards and channels. S2: Forced wake-up, the terminal is activated after receiving the instruction, triggering a high-decibel sound and light alarm to wake up the public; S3: Information interaction: After being awakened, the public receives emergency information through the terminal and can also respond by voice through the terminal; S4: Feedback collection. When the user presses the "I have received" physical button on the terminal, the terminal sends a confirmation receipt signal, which in turn commands the host to receive the receipt signal and provide a voice reply. S5: Closed loop formation: The superior command center displays the "activated" (called) and "responded" (responded) status of the terminal in real time through the visualization module, forming an information closed loop.

[0039] In some embodiments, in step S1, the broadcast instruction includes a pre-recorded voice broadcast instruction and a real-time shouting instruction, and the command host has regional response capability, which can accurately send the instruction to the base station or terminal in the target area.

[0040] In some embodiments, in step S5, the visualization module is built based on a GIS system and can mark the location and feedback status of each terminal in the form of a map, so that the command personnel can intuitively obtain the coverage and effectiveness of information delivery.

[0041] The technical concept of this invention is as follows: The core components of the system include a "call-and-response" base station, a command host, and terminals: The base station is the fixed core of the area, with multi-channel communication to the north (interconnected with the superior command center), a self-organizing network to the south (interconnected with the host / terminal), broadcast transmission (FM + directional loudspeaker), and self-powered capability; The command host is a portable field device that can quickly build a local self-organizing network, realize functions such as "one-click call" to wake up terminals, and feedback reporting, and act as a "mobile command center"; The terminal is a portable in-home device that supports independent communication, forced wake-up (audio and visual alarm), active feedback (physical button + voice), and long-term self-powered capability.

[0042] The system integrates multiple standards and channels (low-power IoT, shortwave data transmission, BeiDou, etc.) to build a decentralized self-organizing network. The operation process follows the "command issuance - forced wake-up - information interaction - feedback collection - situational closed loop": After the command host issues a command, the terminal triggers an audible and visual alarm to wake up the public. After receiving the information, the public provides feedback through buttons / voices. The command center displays the "call / respond" status in real time, ultimately realizing a closed loop of emergency information "issuance - response - confirmation". This achieves a transformation from "blind broadcasting" to "precise calling and responding", and is suitable for emergency broadcasting and command needs in extreme environments of "three interruptions".

[0043] To address the shortcomings of existing technologies, this invention constructs a "wake-up and call-response" emergency broadcast system for extreme environments based on multi-standard and multi-channel fusion technology, aiming to solve the following three core technical problems: ① This addresses the problem of traditional emergency broadcasting completely failing in "communication island" scenarios where power, public network communication, and road transportation are all disrupted due to complex geographical environments such as high mountains and canyons, caused by earthquakes, floods, and mudslides.

[0044] ②The problem of how to deliver emergency evacuation and rescue guidance information to every household and even every trapped person in a mandatory and highly reliable manner, thereby awakening the public who are at rest.

[0045] ③ Solve the problem of how to obtain confirmation feedback from the receiving end so that the local on-site commanders and command centers can understand the coverage and effectiveness of information delivery, and realize the transformation from "blind broadcasting" to "precise response".

[0046] 1) Architecture of the "Wake-up and Response" Emergency Broadcasting System This invention proposes a "wake-up call" emergency broadcasting system and method for extreme environments based on multi-standard and multi-channel fusion. In "triple outage" scenarios, any single communication technology may fail due to infrastructure damage or interference. This system integrates multiple advanced communication technologies, including low-power IoT, data transmission shortwave radio, wireless FM / AM broadcasting, BeiDou emergency communication, and low-cost 5G RedCap+AIoT wireless communication, constructing multiple redundancy and complementary mechanisms. For example, the long-range and robust characteristics of data transmission shortwave communication can compensate for the shortcomings of public network outages; low-power IoT provides high-penetration, low-cost local coverage; and 5G RedCap provides higher bandwidth communication capabilities when some networks are restored or deployed through bastion base stations. This fusion design ensures that information transmission maintains usable communication links even in the most severe environments, thereby maximizing information delivery. Achieving this deep fusion requires solving complex technical problems such as interoperability between different standards, protocol conversion, resource scheduling, and dynamic link selection, but the resulting system resilience is unmatched by any single technical solution. Multi-standard and multi-channel fusion is a significant technological innovation of this invention. The system architecture of this invention is as follows: Figure 1 As shown.

[0047] Depend on Figure 1 It can be observed that this system consists of "wake-up and response" base stations, "wake-up and response" command hosts, and "wake-up and response" terminals, forming a distributed, self-organizing emergency broadcast network. This system architecture breaks through the limitations of traditional emergency broadcast systems' "one-way output," achieving a closed-loop process of "release-response-confirmation" of early warning information under extreme conditions, thus bridging the "last mile" of emergency broadcast dissemination.

[0048] 2) Core components of the system The main functions of each component of this system are as follows: ① "Wake-up and Response" Base Station "Wake-up and Response" base stations are fixed-deployment regional cores, crucial for achieving regional coverage and remote information relay. These base stations are primarily deployed in disaster-prone areas with high population density and at key nodes. The main functions of the base stations are as follows: a) Multi-channel external communication capability (northbound communication) The base station possesses multi-standard, multi-channel external communication capabilities, comprehensively utilizing various methods such as BeiDou short message service, 5G public network, and medium-wave emergency message reception to communicate with the superior emergency broadcasting platform. This multi-channel design ensures that even in the event of partial network outages, the base station can still maintain contact with the outside world, receive instructions from superiors, or report on the situation on-site.

[0049] b) Local self-organizing network communication (southbound communication) The base station is equipped with a data transmission shortwave radio, a low-power Internet of Things (IoT) system, and an FM broadcast transmission subsystem. The "wake-up call" base station, together with the "wake-up call" command host and the wake-up call terminals, forms a southbound self-organizing communication network. The base station can automatically discover and form a network with other base stations, command hosts, and terminals without relying on a central base station, achieving multi-hop routing. The base station effectively enhances the communication coverage and improves broadband communication capabilities of the southbound self-organizing communication network. Furthermore, due to the self-organizing nature of the southbound communication network, even if the base station malfunctions in extreme situations, it does not affect the basic emergency command and communication capabilities of the southbound communication network.

[0050] c) Broadcast function The base station is equipped with FM transmission capability, enabling it to broadcast emergency warnings and command information to "wake-up and response" terminals via FM broadcast. It also features a high-power directional loudspeaker for aerial announcements. This allows the base station to not only send wireless commands but also directly warn and guide residents in the surrounding area via sound. Full coverage of outdoor terminals (such as loudspeaker / megaphone terminals) in administrative villages and key areas is a crucial component of the emergency broadcasting system.

[0051] d) Self-sufficiency in power supply The base station has the ability to supply its own power, which can ensure communication capabilities for a long time in the event of a public power network outage.

[0052] ② "Wake-up and Response" Command Main Unit The "Wake-Up Call" command host is a portable core device used by on-site commanders for "wake-up calls" and command and dispatch. The command host plays a central role in the decentralized network. In a "three-disruption" scenario (disruption of communication, communication, and emergency response), traditional centralized command centers may become ineffective. In this situation, the command host, with its built-in self-organizing network capabilities, becomes a "mobile command center" on-site. This design frees emergency response from reliance on vulnerable external infrastructure, instead decentralizing decision-making and communication capabilities to the disaster site, thereby significantly improving the efficiency and effectiveness of the initial emergency response. The main functions of the command host are as follows: a) Self-organizing network communication capability The command host is equipped with shortwave data radio and low-power IoT communication capabilities, and has built-in self-organizing network and relay functions. Leveraging its built-in self-organizing network and relay capabilities, the command host can quickly establish a local basic emergency broadcast communication network at the disaster site in the event of a "three-out" (disruption of communication, data transmission, and infrastructure) failure, becoming a "mobile command center" for the emergency broadcast system. It can communicate directly with base stations and receiving terminals, enabling localized real-time command and dispatch. As the on-site command center, the command host's self-organizing network and relay capabilities are crucial to ensuring uninterrupted communication even in the absence of centralized infrastructure.

[0053] b) Command and notification functions The command center has a "one-click call" function, which can wake up "call-and-respond" terminals in batches, quickly issue emergency instructions, greatly simplify the emergency command operation process, and improve the efficiency of emergency command and dispatch. The command center also has a feedback and reporting function, which can report the "call-and-respond" feedback to the superior command center.

[0054] c) Self-sufficiency in power supply The command and control unit has a long-term independent power supply capability, which supports its continuous operation at disaster sites for extended periods.

[0055] ③ "Wake-up and Response" Terminal The "wake-up and response" terminal is a portable, independent mobile device pre-deployed in each household and is a core component for realizing the "wake-up and response" closed loop. The main functions of the terminal are as follows.

[0056] a) Independent communication Employing low-power self-organizing network communication technology, it supports data transmission shortwave radio and low-power Internet of Things (IoT). Terminals can form a wireless self-organizing network even without a central base station, enabling direct communication with the "wake-up and respond" command host and other terminals, greatly enhancing communication reliability in harsh environments.

[0057] b) Forced wake-up The terminal has a forced "wake-up" function: after receiving a specific instruction, the receiving terminal can immediately wake up and trigger a high-decibel sound and light alarm, forcibly waking up residents who are resting or unaware of the danger.

[0058] c) "Calling out" feedback The terminal features a forced "call-and-response" feedback function: It includes a "one-click call" and "call-and-response" feedback mechanism. The terminal has a prominent "I have received" physical button (or this button can be integrated with the "one-click call" function). After receiving information and being activated, the user presses the call button or this physical button, and the terminal immediately sends a "call-and-response" confirmation signal to the network. Traditional emergency broadcasting systems generally lack confirmation feedback mechanisms at the individual user level. The "call-and-response feedback" design of this invention is one of its core innovations, transforming one-way broadcasting into two-way interaction and providing the command center with crucial real-time situational awareness data.

[0059] d) Self-sufficiency in power supply The terminal supports low-power standby and has a built-in long-lasting battery to ensure its ability to work continuously for a long time under the "three interruptions" (disconnection, interruption, and interruption).

[0060] The "wake-up and response" terminal plays a crucial role in the "closed-loop" mechanism of emergency broadcasting, with its innovative human-computer interaction being particularly noteworthy. The forced wake-up mechanism directly solves the problem of effectively waking sleeping or unaware-of-danger individuals during a disaster, a challenge difficult to achieve with traditional passive broadcasting methods. The design of the "response feedback" physical button transforms information reception from a passive act to active confirmation, providing commanders with unprecedented, granular feedback information down to the household and even individual level. This invention elevates emergency broadcasting from simple information dissemination to the level of "ensuring awareness" and "verifiable action feedback." It provides on-site commanders and emergency command centers with real-time, actionable information, such as which households have not yet confirmed receiving the information, allowing for targeted deployment of rescue teams. This human-centered design, especially the introduction of the physical feedback button, not only improves the effectiveness and reliability of information transmission but also greatly enhances the accuracy of emergency response, directly solving the problem of "blind broadcasting." A comparison of the "wake-up and response" terminal with existing emergency broadcasting terminals is shown in Table 1.

[0061] Table 1. Comparison of Emergency Broadcast Terminal Functions

[0062] 3) System operation process Please see Table 2 for the main operating flow of this system.

[0063] Table 2. System Operation Flow

[0064] This "wake-up and response" emergency system ensures the effective delivery of emergency information, forced wake-up, and confirmation feedback through a closed-loop operation process, thereby realizing the transformation from the traditional emergency broadcast "blind broadcasting" to "precise response".

[0065] STEP 1. Command Transmission: In case of an emergency, on-site commanders send broadcast commands through the "Wake-up and Response" command host. These commands can be voice announcements or signals to wirelessly activate receiving terminals. The command host has the capability of regional response and comprehensive scheduling of various transmission coverage network resources, similar to an emergency broadcast platform, and can accurately send commands to base stations and receiving terminals in the target area.

[0066] STEP 2. Forced Wake-up: Upon receiving a specific command, the receiving terminal will be immediately wirelessly activated and trigger a high-decibel audible and visual alarm. This forced wake-up mechanism aims to ensure that residents who are resting or unaware of danger are effectively alerted.

[0067] STEP 3. Information Reception and Voice Response: After being awakened, residents receive emergency information through a receiving terminal. This information can be pre-recorded voice broadcasts or real-time announcements from on-site command personnel. Affected residents can also respond via voice through the receiving terminal, providing an initial interactive channel for subsequent "call and response" feedback.

[0068] STEP 4. Call Response Feedback Acquisition: After receiving and understanding the information, residents can send a confirmation signal to the network by pressing the prominent "I have received" physical button on the receiving terminal. Simultaneously, on-site command personnel receive the voice response from the receiving terminal through the command host, further obtaining call response feedback. This physical button design greatly simplifies the feedback process and improves usability in emergency situations.

[0069] STEP 5. Real-time Status Display and Closed Loop: All received confirmation receipts and voice feedback data are transmitted to the command center in real time. The command center's interface displays in real-time, in map form, which terminals have been activated (indicating the information has been "shouted"), and which terminals have pressed buttons or responded with voice (indicating they have "responded"). This forms a complete closed loop of information dissemination and feedback—"dissemination-response-confirmation"—allowing the command center to clearly understand the coverage and effectiveness of information delivery.

[0070] The key technological innovations of this invention include: 1. Multi-standard and multi-channel deep integration technology: Deeply integrates various heterogeneous communication standards such as shortwave data radio, low-power IoT, wireless FM and AM broadcasting, and low-cost 5G RedCap+AIoT to form an emergency broadcast communication network that serves as a backup and complement to each other, greatly improving the system's resilience and communication toughness in extreme environments.

[0071] 2. Decentralized self-organizing network architecture: All nodes in the system ("wake-up and call-out" base stations, "wake-up and call-out" command hosts, and "wake-up and call-out" terminals) have self-organizing network capabilities. They can automatically discover and form a network without the need for a central base station, achieving adaptive routing and self-healing, and ensuring communication continuity under the "three interruptions" conditions.

[0072] 3. Forced wake-up and active feedback mechanism: The system innovatively introduces a forced wake-up (high-decibel sound and light alarm) function for the receiving terminal to ensure effective delivery of information; and sets up a physical button for "I have received" and a voice reply function to enable users to actively confirm and provide feedback, thus solving the problem of one-way blind transmission in traditional emergency broadcasting.
