Abstract
Description
Technical Field
[0001] This invention relates to the field of intelligent emergency service technology, and more specifically, to a one-click triggered emergency call system and service method. Background Technology
[0002] Existing personal emergency call devices, mostly in the form of smart bracelets and watches, have significant shortcomings in their triggering mechanisms. These devices typically place the help button on the side, requiring users to precisely locate and press it. However, in real-world dangerous situations such as falls, limb limitations, or injuries to one arm, this precise operation is often difficult to complete, leading to failed attempts to call for help and preventing the device from playing its due role when most needed.
[0003] In terms of communication support, most existing devices rely on Bluetooth connections to mobile phones for information transmission, lacking independent network communication capabilities. Once the phone is not nearby, runs out of power, or is outside Bluetooth range, the device immediately becomes unusable and unable to send out distress signals. This strong dependence on intermediary devices severely restricts the reliability and usability of the devices in emergency situations.
[0004] Furthermore, from the perspective of service support systems, traditional solutions often rely on simple call transfers or manual judgment in their backend responses, lacking intelligent information processing and decision support. The entire service process, from alarm reception and judgment to resource scheduling, is inefficient, and it is difficult to effectively monitor and verify the execution process of offline service personnel. This results in slow overall response, inaccurate resource matching, and a lack of transparency in the service process, failing to form an efficient and reliable service loop. Summary of the Invention
[0005] In view of the above-mentioned technical problems in related technologies, the present invention proposes a one-click triggered emergency call system and service method, which can overcome the above-mentioned shortcomings of the prior art.
[0006] To achieve the above-mentioned technical objectives, the technical solution of the present invention is implemented as follows: A one-button-triggered emergency call system; The one-click emergency call system includes a wearable user terminal, a central human control service center, and a terminal for offline professionals. The user wearable terminal has an integrated full-surface press-triggered structure on the front of its casing, with multiple micro switches located below the structure; the terminal integrates an anti-accidental touch hardware circuit, an independent communication module, a fusion positioning module, and a hands-free audio module. The manual central control service center is equipped with an intelligent auxiliary answering module and a multi-dimensional dispatch optimization algorithm module. The intelligent auxiliary answering module is used to convert the user's voice information into text and extract key information to generate service suggestions. The multi-dimensional dispatch optimization algorithm module is used to calculate and recommend the optimal service personnel based on service category, user location, service personnel status, and traffic conditions. The offline professional personnel terminal is used to receive work orders, update service status, and upload verification information; The user wearable terminal communicates with the human central control service center through the independent communication module, and the human central control service center communicates with the offline professional personnel terminal.
[0007] Furthermore, the full-surface press-triggered structure covers 70% to 90% of the front area of the housing.
[0008] Furthermore, the number of microswitches is 6 to 12, and they are arranged in an array.
[0009] Furthermore, the anti-accidental touch hardware circuit is an RC delay circuit or an MCU-based hardware timer circuit, which is configured to trigger an emergency request only when the pressing duration exceeds a preset time threshold.
[0010] Furthermore, the independent communication module includes an eSIM chip and LTE or 5G mobile communication radio frequency circuitry.
[0011] Furthermore, the fusion positioning module integrates a satellite positioning chip and a Wi-Fi or base station positioning chip.
[0012] According to another aspect of the present invention, a one-click triggered emergency call service method is provided; The one-click emergency call service method includes the following steps: Step 1: The user initiates a distress request by pressing the full-surface press trigger structure on the wearable terminal. The terminal automatically sends a distress signal containing the user's identifier and location information through its independent communication module. Step 2: The manual central control service center receives the distress signal and uses intelligent technology to recognize and understand the user's voice, automatically generating service suggestions; Step 3: The manual central control service center runs the dispatch optimization algorithm, calculates the optimal service personnel by considering multiple factors, and generates work orders to push downwards; Step 4: Service personnel receive work orders and perform services through terminals, while uploading key statuses during the service process and verification information upon completion in real time; Step 5: After confirming receipt of the verification information, the manual central control service center will perform service loop confirmation and archive and store the entire process data.
[0013] Furthermore, in step one, the anti-accidental touch hardware circuit will perform a delay judgment on the pressing signal to filter out instantaneous accidental touches.
[0014] Furthermore, in step two, the dispatch optimization algorithm integrates at least the following factors: service category, user's real-time location, service personnel's real-time location and status, and real-time traffic conditions.
[0015] Optionally, in step five, the data can be recorded in a blockchain database to form an immutable data chain.
[0016] The beneficial effects of this invention are as follows: By adopting a large-area integrated trigger structure and an anti-accidental touch mechanism, it ensures that users can reliably trigger a distress call when their limbs are restricted, significantly improving the success rate and fault tolerance of operations; by integrating independent communication and multi-mode positioning modules, it eliminates dependence on external devices and ensures the reliability of communication and positioning at critical moments; by constructing a central control center integrating intelligent auxiliary decision-making and intelligent dispatching, it enables rapid understanding of distress call information and efficient instruction conversion, optimizing resource scheduling and shortening response time; by establishing a closed-loop management system for the entire process from triggering to evidence storage, it ensures that each service is traceable and verifiable, comprehensively improving the reliability and quality controllability of emergency services.

In a specific embodiment, in step two, the dispatch optimization algorithm integrates at least the service category, the user's real-time location, the service personnel's real-time location and status, and real-time traffic conditions.
[0030] According to an embodiment of the present invention, a one-click triggered emergency call system and service method is provided. In one optional embodiment, in step five, the data can be recorded in a blockchain database to form an immutable data chain.
[0031] To facilitate understanding of the above technical solutions of the present invention, the following detailed description of the above technical solutions of the present invention will be provided through specific usage methods.
[0032] In practical use, the one-button triggered emergency call system according to the present invention includes a user wearable terminal, a central human control service center, and offline professional personnel terminals; the user wearable terminal adopts a wristband design. Its front cover is a single piece of high-strength composite material, forming a full-surface press-triggered structure, covering approximately 80% of the front area of the housing. Beneath this cover, eight microswitches are soldered onto a circuit board, evenly arranged in a 2×4 array, ensuring reliable triggering by the user pressing any area of the front of the housing with their palm, arm, or other body parts.
[0033] The core control board inside the terminal integrates hardware circuitry to prevent accidental touches. In this embodiment, a delay judgment logic based on the MCU's internal hardware timer is used, with a preset time threshold of 0.5 seconds. Only when the continuous pressing time exceeds this threshold is the system confirmed as a valid emergency call, thus filtering out momentary interference such as everyday bumps and knocks.
[0034] In terms of communication, the terminal has a built-in LTE Cat.1 communication module with an integrated eSIM chip, supporting mainstream LTE frequency bands and enabling mobile data transmission independent of the phone. For positioning, it employs a fusion positioning module, with a multi-mode satellite positioning chip at its core (supporting GPS / BeiDou / GLONASS), supplemented by Wi-Fi positioning and base station positioning technologies to ensure high-accuracy location information even in complex urban environments. The audio module uses a high-sensitivity MEMS microphone and a 1.8W speaker for clear hands-free calls. Power management is handled by an ultra-low-power ARM Cortex-M4 microprocessor, coupled with a large-capacity battery, achieving approximately 10 days of standby time.
[0035] The central human-operated service center is deployed on a cloud server cluster. Its AI-assisted answering module is built on a pre-trained semantic understanding model, which can convert incoming user voice streams into text in real time and automatically extract key information such as "disease type", "degree of discomfort" and "surrounding environment" using named entity recognition (NER) technology, fill them into a structured form, and generate preliminary service suggestions such as "medical assistance" or "safety alarm" within 10 seconds, which are displayed on the screen of the human operator.
[0036] The multi-dimensional dispatch optimization algorithm module runs as a core computing service. Once the agent confirms the service type, the algorithm is activated. It comprehensively considers the urgency of the service (determined by AI suggestions), the user's real-time location, the real-time location and availability of nearby contracted service personnel (such as medical staff and security guards), and real-time traffic conditions obtained from the map service provider. It runs an optimization model that combines the shortest path algorithm (Dijkstra) and multi-attribute decision theory (such as AHP) to calculate the dispatch plan with the lowest overall cost and recommend 1-3 optimal service personnel to the agent.
[0037] The specific implementation method for offline professional terminals and closed-loop processes is as follows: Offline professionals (such as first responders) are equipped with smartphones with a dedicated app installed. This app receives work order pushes from the central control center and can activate map navigation to the user's location with one click.
[0038] In practical use, according to the one-button triggered emergency call system and service method of the present invention, when a user feels unwell or is in danger, he / she only needs to press the front of the terminal worn on the wrist firmly with the palm of his / her hand for about 0.5 seconds, after which the terminal vibrates and issues a voice prompt "Help has been sent".
[0039] Triggering and Reporting: The terminal then sends the pre-stored user ID, the real-time latitude and longitude location information (accuracy of about 5 meters), and the activated voice call stream to the human control service center through its LTE module.
[0040] Intelligent Assisted Decision Making and Intelligent Dispatch: When a call is received at the central control center, the AI module transcribes the user's voice message of "chest pain, shortness of breath" into text in real time, extracts key information, and generates a service suggestion: "Suspected heart problem, emergency medical assistance recommended." After the agent confirms the request, the system runs a dispatch algorithm, considering factors such as the user's location in community A, the availability and proximity of a doctor at nearby hospital B, and current road conditions, recommending that doctor as the optimal candidate and generating a work order.
[0041] Work order execution and status feedback: A doctor's mobile app received the emergency work order, clicked "Accept Order," and immediately started navigation. En route, the doctor clicked "Departed" on the app; upon arriving at the user's location, the doctor clicked "Arrived"; after completing the initial examination and assistance, the doctor clicked "Service Completed" and, as required by the system, uploaded a high-resolution (1080p) photo of the scene as verification information.
[0042] Closed-loop confirmation and data storage: After seeing the "service completed" status and on-site photos uploaded by a doctor in the system, the central control center operator confirms with the user and then clicks "closed-loop confirmation" in the system. All process data of this request for assistance from triggering to completion, including timestamps, location trajectories, voice-to-text transcription, dispatch logic, service node status, and on-site photos, are encrypted and recorded in the consortium blockchain database, forming an immutable service record.
[0043] In summary, by employing the above-mentioned technical solution of this invention, and through the use of an integrated trigger structure covering a large area of the front of the device and a built-in anti-accidental touch mechanism, users can reliably send out distress signals by simply pressing the button even under extreme conditions of limited physical mobility, thereby significantly improving the success rate and fault tolerance of distress calls. By integrating independent mobile communication and multi-mode positioning modules, the system is freed from dependence on other electronic devices carried by the user, thus ensuring the reliable establishment of communication links and accurate location feedback at critical moments. By constructing a central control center integrating artificial intelligence-assisted decision-making and intelligent dispatching algorithms, user distress information can be quickly understood and transformed into efficient service instructions, thereby optimizing the scheduling of offline service resources and shortening the overall response time. Finally, by establishing a fully digital closed-loop management system from distress triggering, work order push, service execution to information feedback and evidence storage, every service process is traceable and verifiable, thus comprehensively ensuring the reliability of the emergency service process and the controllability of service quality.
[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
