Technical Field

[0001] This utility model relates to the field of public safety and emergency communication technology, specifically to an intelligent emergency early warning broadcaster. Background Technology

[0002] In natural disasters or public emergencies, timely and effective early warning information dissemination is crucial for protecting people's lives and property. Traditional emergency broadcasting systems mostly use wired broadcasting or a single radio frequency (FM) method for information transmission, which has many technical shortcomings: Single communication link: Relying on fixed communication lines or wireless signals of specific frequency bands, communication infrastructure is easily damaged in extreme disaster scenarios such as earthquakes and floods, leading to the loss of broadcast system connectivity and the inability to achieve effective early warning; Limited information presentation methods: Only supporting voice broadcasting, lacking visual aids, it is difficult to meet the information access needs of hearing-impaired people, and the propagation effect is poor in high-noise environments; Crude broadcast control: Most systems do not have regional directional broadcasting capabilities, often adopting a "wide-area broadcasting" mode, which can easily cause panic among people in non-disaster areas and reduce public trust; Difficult operation and maintenance management: Equipment status monitoring relies on manual inspections, making it impossible to grasp operating parameters and fault conditions in real time, resulting in low maintenance efficiency and delayed response.

[0003] Therefore, there is an urgent need to provide a new type of intelligent emergency warning broadcasting device with multi-channel redundant communication, multi-modal information output, remote status monitoring, and scalable linkage capabilities. Summary of the Invention

[0004] To address the aforementioned issues, this utility model provides an intelligent emergency warning broadcaster, a novel intelligent emergency warning broadcasting device with multi-channel redundant communication, multi-modal information output, remote status monitoring, and expandable linkage capabilities.

[0018] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0019] Example 1: See Figures 1 to 2The main control chassis 1 is a fully sealed metal shell made of stainless steel or aluminum alloy, with an IP65 or higher protection rating, providing waterproof, dustproof, corrosion-resistant, and impact-resistant properties. Internally, it features mounting rails and a heat dissipation structure to house the main controller and other electronic components. The outer wall has grounding terminals and lightning protection circuits to ensure safe operation during thunderstorms. The multi-mode communication module is located inside the main control chassis 1 and is electrically connected to the main controller's data input port. This module integrates three heterogeneous communication units: a 4G / 5G cellular communication unit supporting mainstream operator network standards for receiving early warning commands from the emergency command center under normal conditions; a satellite communication unit, preferably using a BeiDou short message communication module, compatible with GPS data reception, enabling bidirectional communication in areas without terrestrial network coverage, particularly suitable for mountainous areas, islands, and border regions; and an Ethernet communication unit that connects to a local area network or fiber optic private network via an RJ45 interface, suitable for densely populated urban deployment scenarios. These three communication units are connected in parallel to the main controller, forming a hot-backup communication architecture. The main controller has a built-in link quality assessment algorithm that monitors the signal strength, bit error rate and latency of each channel in real time. Once the primary channel is interrupted, it automatically switches to the backup channel to ensure that warning commands can be continuously delivered.

[0020] Specifically, the audio power amplifier module is connected to the audio output terminal of the main controller. After receiving the digital audio signal, it performs D / A conversion and power amplification to drive the external tweeter 5 to emit sound. This module supports MP3 / WAV audio playback, has a built-in large-capacity storage chip, and pre-stores multi-level early warning voice templates (such as typhoon, earthquake, fire, etc.), which can be called and played in a loop according to instructions. At the same time, this module is also connected to an omnidirectional microphone 7 to collect ambient sound or management personnel's voices, and transmits them back to the command center via the communication module to realize two-way voice interaction.

[0021] Specifically, the visual warning module includes an LED display screen 2 and red and blue warning lights 3, both of which are mounted on the mounting bracket 4 on the top of the main control chassis, facing the public's line of sight.

[0022] Furthermore, the LED display screen 2 is an outdoor high-brightness full-color LED screen with a brightness of not less than 5000 cd / m², supporting clear display under direct sunlight; its display content includes text alerts (such as "Red Alert for Geological Disasters"), graphic symbols (such as evacuation arrows), dynamic scroll bars, and generated QR codes; the QR codes link to the official website or mini-program page of the emergency management department, and scanning the code can view detailed disaster descriptions, evacuation routes, distribution of material points, and other extended information.

[0023] Furthermore, the red and blue warning lights 3 are composed of a high-brightness LED array, and a flashing controller is used to adjust the light emission mode: for example, alternating flashing is used for major emergencies, synchronous fast flashing is used for fire alarms, and slow flashing is used for general reminders. Different modes are automatically configured by the main controller according to the warning type, enhancing the visibility.

[0024] Specifically, the power management module is responsible for the power supply of the entire system, ensuring stable operation under various power supply conditions. It includes: a mains power access unit: connected to the AC 220V mains grid, supplying power to the main system and charging the battery; a battery unit: using lithium iron phosphate battery packs, rated voltage DC 12V or 24V, capacity ≥50Ah, supporting continuous operation for more than 72 hours after a power outage; and a solar charging controller: connected to an external solar panel 6, with a maximum input power of 300W, and equipped with MPPT (maximum power point tracking) function to improve photoelectric conversion efficiency; it utilizes sunlight to supplement power during the day and is powered by the battery at night, enabling long-term off-grid operation. This module has built-in power switching logic, prioritizing mains power when it is normal; and automatically and seamlessly switching to battery power within 0.1 seconds after a power outage to avoid broadcast interruptions.

[0025] Specifically, the status acquisition module consists of two parts: a built-in sensor group and an external sensor interface. The built-in sensor group is integrated inside the main control chassis and includes: a temperature sensor: monitoring the temperature rise inside the chassis to prevent high temperature damage to components; a voltage sensor: detecting power supply voltage fluctuations in real time; a tilt sensor (MEMS accelerometer): determining whether the equipment has tipped over (e.g., being washed away by a flood or vandalized); a vibration sensor: identifying severe vibration events to assist in determining the occurrence of geological disasters; and a network signal strength detection unit: periodically measuring the current communication link RSSI value to assess communication quality.

[0026] Specifically, external sensor interfaces are led out through a waterproof junction box, supporting the connection of: water level sensors: deployed along rivers and reservoirs to monitor rising water levels; rainfall sensors: collecting rainfall data for meteorological early warning linkage; and surface deformation and displacement sensors: installed at landslide hazard points to detect minute soil displacements. All sensor data is collected periodically by the main controller (every 5 minutes by default), packaged, and uploaded to a cloud monitoring platform, supporting remote viewing, threshold alarms, and trend analysis.

[0027] Specifically, the main controller is based on a high-performance ARM architecture processor (such as the STM32H7 series or NXP i.MX RT series), running an embedded Linux or FreeRTOS operating system, and features functions such as task scheduling, protocol parsing, data encryption, and log recording. Its core functions include: parsing received warning commands and triggering corresponding audio, light, and display actions; implementing targeted broadcast control based on GIS coordinates: combining BeiDou / GPS positioning information to send commands only to broadcasters within the affected area, avoiding false alarms and disturbances; supporting remote firmware upgrades (OTA) for future function optimization; and recording operation logs and event logs for post-event traceability.

[0028] Specifically, the top of the main control chassis 1 is welded or bolted with a column-type mounting bracket 4, and the high-volume speaker 5, LED display screen 2 and red and blue warning lights 3 are arranged horizontally and fixed on the bracket to form an integrated appearance structure, which is both aesthetically pleasing and convenient for centralized maintenance.

[0029] Specifically, the main control chassis has an independent waterproof junction box on one side, with a protection level of IP68, and internally arranged terminal blocks and communication interfaces. The key component is the UAV communication interface 11, which uses an industrial-grade aviation connector (such as M12 or XLR type) and supports RS485 or CAN bus communication protocols.

[0030] Once an emergency drone carrying a portable broadcast terminal arrives at the scene, it can quickly connect via this interface to perform the following operations: the broadcaster transmits local environmental data to the drone; the drone sends the latest disaster information to the broadcaster and broadcasts it together; a temporary local area network is built to assist in restoring local communication; and it acts as a relay node to extend the wireless communication distance.

[0031] During use, the following situations may occur: Under normal conditions, the device maintains a heartbeat connection with the county-level emergency command platform through the 4G network and uploads status data such as device temperature, battery voltage, and signal strength at regular intervals.

[0032] The day's rainfall reached a critical level, and water level sensors deployed in the upstream river detected a rapid rise in water level, uploading the data to the platform via the status acquisition module of the broadcasting system. The platform activated its flood prevention plan, sending an orange alert to all broadcasting systems in the area.

[0033] Upon receiving the instruction, the main controller immediately initiates the response process: it retrieves a pre-stored audio file, which is then amplified by the audio power amplifier module and used to drive the loudspeaker to play repeatedly: "Attention! The upstream river is surging; please evacuate low-lying areas immediately!"; it controls LED display screen 2 to display "Orange Flood Warning" on an orange background and generates a map containing the location of shelters. Figure 2QR code; activate the red and blue warning lights in "alternating flashing" mode to attract pedestrians' attention; simultaneously, transmit the current device status (normal power supply, uninterrupted communication) back to the platform to confirm that the command has been executed. If the 4G signal is interrupted due to a lightning strike, the broadcaster will automatically switch to the Beidou short message channel to receive subsequent commands, ensuring uninterrupted communication.

[0034] In another landslide, road closures prevented rescue teams from reaching the site. An emergency drone carrying a lightweight broadcast module flew to the scene and landed next to a broadcasting unit. The operator inserted its communication cable into the drone's communication interface 11 inside a waterproof junction box. After establishing an RS485 connection, the broadcasting unit transmitted locally collected surface displacement data to the drone and assisted it in completing a new round of broadcasting tasks, forming a collaborative response loop.

[0035] In addition, during sunny days, the solar panel 6 continuously charges the battery, while at night the battery powers the system. The entire system can operate for a long time without external mains power, making it energy-saving and environmentally friendly.

[0036] The intelligent emergency early warning broadcaster provided by this utility model not only solves the problems of unreliable communication, single function, and difficult operation and maintenance of traditional broadcasting equipment, but also achieves the unification of communication redundancy, information diversification, intelligent operation and maintenance, green energy and system scalability through technological innovation. It has broad application value and is suitable for various scenarios such as urban and rural communities, tourist attractions, transportation hubs, industrial parks, and water conservancy facilities.

[0037] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
