A multi-imsi IoT smoke detector and a smoke detection method

Abstract

This Hong Kong-based company has disclosed a multi-IMSI IoT smoke detector and a smoke detection method. The method includes: registering and binding the user's phone number on an instant messaging platform by scanning a QR code on the smoke detector's casing; when the detector detects smoke particles exceeding a safety threshold, transmitting a payload data containing alarm information to a 4G service provider and the cloud via a built-in antenna; the cloud forwarding the data to an AI-based server; the server interpreting the data and generating a human-readable notification message, which is then automatically sent to the registered user's mobile phone via the instant messaging platform. The combination of multi-IMSI redundancy and direct instant messaging provides a highly reliable alarm function, requiring no user intervention, application dependency, or additional hardware, making it ideal for use in homes, elderly care facilities, rental properties, and remote areas.

Description

HK 30138171 A Specification 2: When a safety threshold is exceeded, a digital trigger signal is sent to the microcontroller; Upon receiving the digital trigger signal, the microcontroller is activated, reads the SIM card status, autonomously selects and switches mobile operators to maintain a smooth 4G network connection, notifies the alarm to sound an alarm, constructs a small JSON payload data, and sends it to the IoT 4G communication module; The IoT 4G communication module transmits the payload data sent by the microcontroller to the 4G service provider via an antenna; The casing has an anti-tamper button, status indicator lights, and a QR code for binding. Furthermore, the JSON payload data includes at least the detector ID, time, alarm type, smoke severity, temperature, and battery status. Furthermore, the smoke sensor is a dual photoelectric sensor. A detection method based on the aforementioned multi-IMSI IoT smoke detector includes the following steps: Step 1, installing the multi-IMSI IoT smoke detector at a selected suitable location, and registering and binding the detector to the user's phone number on an instant messaging platform by scanning a QR code on the casing; Step 2, when the detector detects smoke particles exceeding a safety threshold, transmitting the payload data to a 4G service provider via the MQTT communication protocol through the built-in antenna; Step 3, after receiving the data, the 4G service provider sends the data to the cloud via the MQTT communication protocol; Step 4, the cloud forwards the data to an AI-based server via the HTTP communication protocol; Step 5, the AI-based server interprets the data and composes a human-readable notification message, which is automatically sent to the registered user's mobile phone via the instant messaging platform through the HTTP communication protocol. Further, in Step 1, after the user scans the QR code, the user's mobile phone automatically connects to the AI-based server, and a chatbot guides the user through product registration and setup. Further, one detector can be bound to multiple phone numbers. This short-term smoke detector and method proposed in Hong Kong achieves reliable remote alarms through multi-network cellular redundancy and direct instant communication platform notifications (HK 30138171 A). No user application, local gateway hardware, or wired power connection is required. It is suitable for residential fire safety, elderly / independent living monitoring, commercial premises without IT infrastructure, and areas where single-network coverage is unreliable, where easy installation and reliable instant notifications are crucial.Brief Description of the Drawings To more clearly illustrate the technical solutions in the embodiments or prior art of this Hong Kong Short-Term Device, the drawings used in the description of the embodiments or prior art will be briefly introduced below.

Therefore, they have no substantial technical significance. Any modifications to the structure, changes in the proportional relationships, or adjustments to the size, without affecting the effectiveness and purpose achieved by this Hong Kong Short-Term Device, should still fall within the scope of the technical content disclosed in this Hong Kong Short-Term Device. Meanwhile, the terms such as "above," "below," "left," "right," "middle," and "one" used in this specification are merely for clarity of description and are not intended to limit the scope of implementation in Hong Kong in the short term. Changes or adjustments to their relative relationships, without substantial changes to the technical content, should also be considered as part of the scope of implementation in Hong Kong in the short term. The following is an explanation and definition of the terms involved in this Hong Kong short term: | English Abbreviation | English Original | Chinese Name | Core Definition | |---|---|---|---|---| | IMSI | International Mobile Identifier | A globally unique 15-bit digital code that identifies a mobile user and is used for authentication and addressing of the core network's Subscriber Identity. | | SIM | Subscriber Identity Module | A user identity module that typically refers to a physical chip card that stores the IMSI, key, and user information, serving as the physical credential for accessing the operator's network. | | JSON | JavaScript | Object Notation | A lightweight, text-based, language-independent data exchange format that organizes data in an easy-to-read and write key-value pair structure. It is currently the common standard for API and Web data transmission. An ID Identifier is a string or number of characters used to uniquely identify an object, user, device, or entity within a system.MQTT (Message Queuing Telemetry Transport) is a featherweight messaging protocol based on a publish / subscribe model, designed for low-bandwidth, unstable networks (such as the Internet of Things) to achieve efficient bidirectional communication. HTTP (Hypertext Transfer Protocol) is an application-layer protocol for distributed, collaborative, hypermedia information systems, forming the foundation of data communication on the World Wide Web, defining the request / response format between client and server. AI (Artificial Intelligence) is a branch of computer science dedicated to creating intelligent agents capable of performing tasks typically requiring human intelligence, including learning, reasoning, perception, understanding, and language interaction. As shown in Figure 1, this paper proposes an end-to-end detection method based on multi-IMSI IoT smoke detectors. The multi-IMSI IoT smoke detector is a completely independent, battery-powered security device whose core features eliminate the following requirements: - any user-installed mobile application, - any local gateway or hub, - any wired power supply (powered solely by an internal battery). Figure 2 shows a simplified block diagram of a single-layer connectivity architecture that connects a smoke detector device directly to the cloud via a 4G cellular network, emphasizing the elimination of intermediate gateways. Specifically, the multi-IMSI IoT smoke detector includes a housing and built-in smoke sensors, an alarm, a multi-IMSI IoT SIM card reader module, an IoT 4G communication module for continuous 4G connectivity, a microcontroller, a battery for power supply, and an antenna. The multi-IMSI IoT SIM card reader module is pre-installed with at least two IMSI profiles from different mobile operators. The smoke sensor detects smoke particles. When no smoke particles are detected or the concentration of detected smoke particles does not exceed a safety threshold, each module within the detector is in a dormant state. When the smoke sensor detects that the smoke particle concentration exceeds the safety threshold, it sends a digital trigger signal to the microcontroller. Upon receiving this digital trigger signal, the microcontroller is activated, reads the SIM card status, and autonomously selects and switches mobile operators to maintain a smooth 4G network connection. (Figure 3 shows a schematic diagram of the multi-IMSI redundancy mechanism, illustrating that the detector can switch between at least two independent service providers (e.g., provider A and provider B) based on real-time network availability and signal quality.)The system notifies the alarm to sound an alarm, constructs a small JSON payload data, and sends it to the IoT 4G communication module. The IoT 4G communication module then transmits the payload data sent by the microcontroller to the 4G service provider via an antenna. The casing has an anti-tamper button, status indicator lights, and a QR code for binding. In one embodiment, the JSON payload data includes at least the detector ID, time, alarm type, smoke severity, temperature, and battery status. In one embodiment, the smoke sensor is a dual photoelectric sensor. In one embodiment, the battery life is guaranteed for at least three years of operation. In one embodiment, the detector is completely in a dormant, passive state before issuing an alarm, consuming very little power, and requires no user setup except for initial phone number registration (handled during purchase / activation). A detection method based on the aforementioned multi-IMSI IoT smoke detector includes the following steps: HK 30138171 A Specification 6 Step 1: Install the multi-IMSI IoT smoke detector at a selected suitable location, and register and bind the user's phone number on an instant messaging platform by scanning the QR code on the casing; Step 2: When the detector detects smoke particles exceeding a safety threshold, it transmits the payload data to a 4G service provider via the MQTT communication protocol through its built-in antenna; Step 3: After receiving the data, the 4G service provider sends the data to the cloud via the MQTT communication protocol; Step 4: The cloud forwards the data to an AI-based server via the HTTP communication protocol; Step 5: The AI-based server interprets the data and writes a human-readable notification message, which is automatically sent to the registered user's mobile phone via the instant messaging platform through the HTTP communication protocol. In one embodiment, in Step 1, after the user scans the QR code, the user's mobile phone automatically connects to the AI-based server, and a robot customer service guides the user to complete product registration and setup. In one embodiment, a single detector can be linked to multiple phone numbers. The smoke detector and method proposed by this Hong Kong Short-Term Provider combine multiple IMSI redundancy with direct real-time communication transmission, providing highly reliable alarm functionality without user intervention, application dependency, or additional hardware, making it ideal for home, elderly care, rental properties, and remote areas.
