The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] Embodiment Refer to Figures 1-4 As shown, a Beidou positioning device for life jackets includes: A Beidou-3 RDSS communication chip; A single Beidou positioning module; An antenna; A water-entry trigger chip; A low self-consumption battery; Indicator light 1; Button 2; A back buckle 3 wearing structure; The Beidou positioning device for life jackets accesses the network through Beidou-3 and is connected to the background management platform, and can send alarm information and location information to the management platform when encountering water or being manually triggered.

[0024] Traditional life jackets usually lack accurate positioning functions and cannot provide accurate rescue positions. By integrating the Beidou-3 positioning module and communication chip, the position information of the user can be obtained in real time, and it is connected to the background management platform through the Beidou system to ensure that accurate alarm information and location information are sent in time when a person falls into the water or is manually triggered, solving the problem that traditional life jackets cannot timely feedback position information.

[0025] Traditional life jackets generally require users to manually trigger an alarm, which may lead to slow response in case of emergency. The water-triggered chip in this solution can be automatically activated and send an alarm when the user falls into the water, reducing the interference of human factors and ensuring that the rescue response is triggered in the shortest time, thus solving the problem that traditional life jackets cannot automatically send out alarms.

[0026] To ensure that the life jacket can work for a long time in case of emergency, this solution adopts a low self-consumption battery, optimizes the battery usage efficiency, and reduces the dependence on frequent charging. This design ensures that the device can remain in an effective working state for a long time, solving the problems of high energy consumption and inability to standby for a long time of traditional life jackets.

[0027] Through the design of indicator light 1 and button 2, users can clearly understand the working status of the device, respond in time and trigger manually, improving the operation convenience of users. The wearing structure of back buckle 3 makes the life jacket more adaptable and comfortable, enhancing the wearing experience and safety of users.

[0028] After being connected to the background management platform, rescue personnel can obtain the location where the incident occurs in real time and optimize the dispatch according to the rescue resources in different locations, greatly improving the rescue efficiency. Traditional life jackets do not have this intelligent dispatching function, and the rescue response is slow. This solution solves the problems of long rescue response time and low efficiency of traditional rescue through intelligent management.

[0029] The Beidou positioning device of the life jacket adopts the wearing method of back buckle 3, and a wireless charging area 4 is arranged below the back buckle 3, which can charge the device wirelessly; the device includes a sensing line 5 connected to the device, and the sensing head of the sensing line 5 is a water contact sensor 6, which can automatically activate the alarm system when the device touches the water surface, enter the water falling alarm state, and activate the indicator light 1 and alarm system of the device, and upload the device location information and status to the management platform.

[0030] The wearing structure of back buckle 3 enables users to easily wear and adjust the life jacket to adapt to different body types, improving the wearing comfort and stability. In addition, the design of back buckle 3 can ensure the stability of the device and reduce the discomfort during activities.

[0031] There are back buckle 3 and wireless charging area 4, which can provide electrical energy for the device through wireless charging, avoiding the inconvenience and interface wear problems that may be brought by traditional wired charging. Wireless charging enhances the waterproof performance of the device, reduces the risk of external interface exposure, and extends the service life of the device; through the water contact sensor 6, the device can automatically sense the water surface contact. Once the user falls into the water, the system will automatically activate the alarm function and enter the water falling alarm state. This function ensures that even if the user cannot operate manually, the device can still trigger an alarm at a critical moment to ensure timely rescue.

[0032] The device uploads location information and device status to the management platform in real time through the Beidou system, ensuring that rescue personnel can quickly obtain accurate positioning and device status, thereby improving rescue efficiency, reducing search and rescue time, and ensuring user safety. Combined with the water contact sensor 6, the indicator light 1, and the alarm system, the solution provides multiple safety guarantees. When the device activates the alarm, the indicator light 1 can help surrounding personnel quickly identify the alarm status, increasing the visibility of the device and further improving the response speed in emergency situations.

[0033] Intelligent functions such as wireless charging, automatic trigger alarm, and real-time information upload greatly improve the operation convenience and user experience of the device. Users don't need to worry about complex operation steps, and the system automatically senses and responds to ensure that the device is always in the best working state.

[0034] The manual SOS alarm function of the device is activated by pressing the button 2 on the device. The indicator light 1 turns yellow, and the device enters the SOS alarm state and uploads the device location information and alarm signal to the management platform. The operation to cancel the SOS alarm state is: when the device indicator light 1 is on, press the button 2 at least three times continuously. After the indicator light 1 flashes twice green and then goes out, it means that the SOS alarm state has been successfully cancelled.

[0035] Activating the SOS alarm function through the button 2 enables users to quickly and easily send a distress signal in an emergency. Just press the button to trigger the alarm system. This intuitive and easy-to-understand operation method can effectively reduce the operation difficulty in an emergency and improve the convenience of use. When the indicator light 1 of the device turns yellow, it can clearly prompt users and surrounding people that the device has entered the SOS alarm state, increasing the visibility of the device. In a night or poor visibility environment, the yellow light state can help rescue personnel quickly identify the location of the alarm device.

[0036] When activating the SOS alarm, the device will upload location information and alarm signals to the management platform in real time, ensuring that rescue personnel can obtain accurate location information in the first place. This can greatly improve rescue efficiency, reduce response time, and ensure user safety. Canceling the SOS alarm state requires pressing the button 2 at least three times continuously, and the indicator light 1 flashes twice green and then goes out. This design can effectively avoid misoperation. In an emergency, users can clearly confirm whether the alarm has been truly cancelled, avoiding affecting the rescue process due to accidental triggering or accidental cancellation of the alarm.

[0037] Combined with the button 2, the indicator light 1, and the upload of location information, the solution provides multiple safety guarantees. When the device enters the SOS state, the indicator light 1, the alarm signal, and the real-time feedback from the management platform work together to ensure that the device is in the correct alarm state. At the same time, the complexity of canceling the alarm operation effectively prevents unintentional interruptions; users can complete the cancellation by simply operating the button 2 when they clearly confirm that they need to cancel the SOS alarm, enhancing the user's sense of control over the device. For alarms that have not been canceled for a long time, rescue personnel can judge whether the device is still in the alarm state through the feedback of the indicator light 1 and thus carry out appropriate intervention.

[0038] The device also includes a continuous positioning function. The user starts the continuous positioning mode by pressing the button 2, and the indicator light 1 turns blue, and the device uploads the location information in real time; the continuous positioning state can be canceled by operating the button 2, and the indicator light 1 flashes twice with the green light and then goes out, indicating that the continuous positioning state has been successfully canceled.

[0039] By pressing the button 2 to start the continuous positioning mode, the device can upload the location information in real time. This means that regardless of the environment or activity state of the user, the management platform can obtain the location information of the device at any time, so as to continuously monitor the safety status of the user, which is particularly important during water activities or in places far from rescue.

[0040] Users can flexibly enable or cancel the continuous positioning mode according to actual needs. Starting and stopping the positioning by operating the button 2 enables the positioning function of the device to provide continuous location information when needed and turn it off when not needed, avoiding unnecessary battery consumption and data upload; starting and canceling the continuous positioning function by operating the button 2 is simple and intuitive, and users can quickly understand and master the functions of the device. The indicator light 1 turning blue indicates that the positioning mode is started, and the green light flashing indicates cancellation. The operation feedback is clear and easy to understand, ensuring that users can quickly respond in emergency or complex environments.

[0041] The start and cancellation of the continuous positioning function can help save the battery power and data traffic of the device. When continuous positioning is not needed, users can extend the usage time of the device and avoid unnecessary consumption by canceling the function, improving the energy efficiency and resource utilization rate of the device; in the continuous positioning mode, the device continuously uploads location data, which helps to ensure higher-frequency data updates and more accurate positioning. This is crucial for rescue personnel to understand the real-time location of the device, especially in vast or uncertain environments; users can independently control the start and stop of the positioning mode, enhancing the personalization and autonomy of the device. When users need to carry out long-term activities or are in potentially dangerous environments, they can start the continuous positioning mode to ensure that they can always know their location and stop it in time when it is no longer needed, avoiding over-positioning.

[0042] The device ensures effective communication and data transmission even in areas without signal through Internet of Things technology; after the alarm information is uploaded, indicator light 1 goes out and the device enters the standby mode until relevant information is uploaded again at the start of the next working mode; the management platform includes a communication server and a central server, which are used to receive the location information and alarm information from the device, and conduct device status monitoring and data statistical analysis.

[0043] The application of Internet of Things technology ensures that the device can conduct effective communication and data transmission even in areas without traditional signal coverage (such as remote areas or underground environments). Through advanced communication technologies (such as low-power wide-area network (LPWAN), satellite communication, etc.), the device can ensure that alarm information and location information can always be uploaded in case of emergency, guaranteeing user safety; after the alarm information is uploaded, the device will automatically enter the standby mode and indicator light 1 goes out, reducing the energy consumption of the device in the non-working state. This energy-saving design not only extends the service time of the device, but also reduces battery consumption and improves the long-term use efficiency of the device, especially suitable for scenarios with long-term standby.

[0044] After uploading information, the device automatically enters the standby mode, avoiding unnecessary continuous operation and being activated again only when the next working mode starts. This automated management makes the device operation more convenient, without the need for users to intervene manually frequently, reducing the operation complexity of the device; through the communication server and the central server, the management platform can receive the location information and alarm information uploaded by the device in real time, and conduct status monitoring and data statistical analysis. This enables managers to grasp the usage status of the device, the distribution location of the device, and the handling situation of alarm events at any time, improving the response speed and decision-making efficiency.

[0045] The central server can conduct statistical analysis on the historical data uploaded by the device to help managers evaluate the working condition of the device, the alarm frequency, and user needs. Through in-depth analysis of the data, the operation strategy of the device can be optimized, potential faults or safety hazards can be predicted in advance, and data-based intelligent decision-making support can be provided; through Internet of Things technology, the device can continuously transmit alarm information and location information to ensure that danger signals will be conveyed in a timely manner regardless of where the user is. The real-time monitoring of the management platform can take measures quickly in case of anomalies, dispatch rescue resources, and provide more comprehensive safety protection for users; the management platform can conduct remote monitoring and management of the device, including real-time query of the device status, real-time analysis of alarm information, and tracking of the device location. This provides great convenience for the maintenance, management, and dispatch of the device, improving the efficiency of device management.

[0046] A Beidou positioning method for life jackets includes the following steps: Obtain the real-time location information of the user through the Beidou-3 satellite system; Judge whether the user has fallen into the water through the sensors on the device. If it is judged that the user is in the state of falling into the water, the alarm function will be automatically activated. In the state of falling into the water, the location information and alarm signal of the device are uploaded to the background management platform in real time. Receive the location information and alarm signal through the background management platform, conduct real-time monitoring and issue rescue instructions.

[0047] Through the precise positioning of the Beidou-3 satellite system, the location information of the user can be obtained in real time. Once the user enters the state of falling into the water, the system will automatically activate the alarm to ensure accurate rescue positioning in the shortest time. This method combines Beidou satellites and Internet of Things technology to ensure real-time transmission of location information even in areas with poor signals or remote areas, improving the success rate of rescue.

[0048] The device automatically judges whether the user has fallen into the water through the sensor without manual operation, reducing the interference of human factors and improving the response speed. Automatic alarm and real-time upload of location information reduce the time delay of traditional manual alarm, thus shortening the rescue response time.

[0049] The background management platform receives the alarm signal and location information in real time. The management platform can immediately analyze and issue rescue instructions to rescue personnel or organizations, quickly allocate resources for rescue. The system has a continuous monitoring function, which can timely master the state changes of users and further improve the emergency handling efficiency.

[0050] The device can not only automatically alarm through the water contact sensor, but also trigger the SOS alarm manually by the user, providing multi-level safety protection to adapt to different situations. The alarm status is reminded to the user through the change of the indicator light color to avoid misoperation. The life jacket maintains a continuous connection with the background platform through Internet of Things technology, and can ensure data upload and alarm transmission even in areas without signals. Data analysis can also provide support for post-event statistics and optimization.

[0051] Integrate the Beidou-3 RDSS communication chip and positioning module in the life jacket to ensure that the device can stably access the Beidou satellite network and conduct real-time positioning. Configure a high-precision water contact sensor to detect whether the user has fallen into the water. The sensor can quickly respond to the water surface contact and activate the alarm function. Integrate a low-power design to extend the device usage time, especially to maintain low battery consumption during the long-term use of the life jacket.

[0052] Construction of the background management platform: Develop a powerful back-end platform with the ability to receive, store, and analyze real-time location information and alarm signals from devices; the management platform should be able to monitor multiple user devices in real time, receive alarm information, generate rescue instructions, and push them to relevant personnel; configure an intelligent rescue decision support system that can efficiently command and dispatch according to the user's location, emergency situation, and rescue resource situation.

[0053] Application of Internet of Things technology: Utilize Internet of Things technology to ensure that even when the device enters a signal-free area, data transmission can still be carried out through base stations or relay devices to ensure the real-time nature of information; adopt cloud computing technology to ensure the processing and storage of massive data for subsequent analysis and optimization of rescue plans.

[0054] User operation interface: The buttons and indicator lights on the life jacket need to be simple and intuitive, so that users can easily understand the status of the device. For example, when the device enters the SOS alarm state, the indicator light turns yellow; when entering the continuous positioning mode, the indicator light turns blue; the device should have a manual alarm function in case of emergency, and the user triggers the SOS state by pressing a button, which is convenient for users to alarm in any situation.

[0055] System testing and training: The device and system need to undergo strict testing to ensure normal operation in various environments, especially in extreme weather, different waters, and different signal conditions; train users to help them understand how to operate the device and how to use the manual alarm function to seek help in case of emergency.

[0056] Continuous optimization and maintenance: The life jacket system needs to be maintained and upgraded regularly, especially the hardware, communication chips, and software platform parts. Regular technical support and upgrades can ensure the long-term stable operation of the device; collect users' usage feedback to optimize alarm accuracy, system response speed, and user experience.

[0057] The method includes the step of judging whether the user has fallen into the water, which is realized by a water touch sensor. When the sensor detects water surface contact, it automatically enters the falling water alarm state; the method includes the step of the user manually activating the SOS alarm function. The user triggers the SOS alarm mode by pressing a button on the life jacket, and uploads the alarm signal and location information to the back-end management platform; the SOS alarm mode prompts the activation of the alarm state of the user through the color change of the indicator light. When the indicator light turns yellow, it means that the device enters the SOS alarm state.

[0058] The device automatically detects whether the user has fallen into the water through a water contact sensor. When the user enters the water and triggers the sensor, the system will immediately enter the alarm mode without the need for manual operation by the user. This can minimize the rescue response time, especially in cases where the user is unable to call the police in time by themselves, reducing rescue delays caused by slow reaction; in critical situations, the user can manually trigger the SOS alarm by pressing a button, further enhancing the user's safety guarantee when the automatic system fails to trigger the alarm.

[0059] Through the color change of the indicator light (yellow indicates the SOS alarm status), the user can clearly see whether the alarm status is activated, avoiding confusion or misoperation caused by unclear device status. This visual feedback system increases the user's understanding of the device's functions, enhancing the overall user experience and trust; the design of the manually activated SOS alarm function makes the device easier and more intuitive to use, enabling users to react quickly and initiate rescue even if they are not familiar with the device in an emergency.

[0060] When the device enters the SOS alarm mode, the system will upload the user's location information and alarm signal to the background management platform in real time, ensuring that rescue personnel can quickly obtain accurate location information. The background platform can process the real-time data quickly and formulate corresponding rescue plans; the combination of automated and manual alarms avoids the situation of missing the best rescue opportunity due to human negligence or misjudgment, increasing the success rate of rescue.

[0061] The dual mechanisms of the system's automatic alarm (triggered by the water contact sensor) and manual alarm (pressed by the user) can ensure alarm triggering in different situations, avoiding the risk of a single system failure or the user's failure to react in time; whether the user unconsciously triggers the alarm in the water or actively triggers the SOS signal, the system can respond accordingly to meet the needs of different emergency situations.

[0062] All alarm signals and location information are transmitted to the background management platform in real time, allowing rescue personnel to monitor the user's status in real time and conduct precise rescue dispatching and command. Compared with traditional methods, this system can notify the appropriate rescue team in the shortest time, improving rescue efficiency; due to the timely upload of accurate location information, rescue personnel can clearly know the specific location of the trapped person, reducing the search time and improving the rescue response speed and effect.

[0063] The cooperation of the water contact sensor and the SOS alarm button reduces the need for manual intervention, making the entire rescue process faster and more automated, reducing human errors; the background platform has centralized information processing and dispatching capabilities, enabling it to coordinate multiple rescue resources, thus effectively improving the overall rescue efficiency.

[0064] The method includes a continuous positioning mode. The user starts this mode by pressing a button on the device. The device enters the continuous positioning state and uploads location information to the background management platform at regular intervals. In the continuous positioning state, the device will continuously upload location information until the user manually cancels this mode or the device enters the standby state.

[0065] When in the continuous positioning mode, the device will regularly upload the user's location information, and the background management platform can monitor the user's location in real time. This provides full - process tracking and guarantee for the user, especially suitable for high - risk environments such as hiking, outdoor sports or maritime activities, enhancing the user's sense of security. If the user encounters an emergency or loses contact, the background platform can immediately obtain accurate location information and quickly locate the user's position, thus improving the timeliness and accuracy of rescue response.

[0066] The user only needs to press a button on the device to start the continuous positioning mode. The operation is simple and suitable for various scenarios. There is no need for cumbersome settings or operations, and it can be quickly activated in case of emergency, ensuring that the user will not miss important time due to complex operations. The user can cancel the continuous positioning mode at any time, providing flexibility. For example, when the user no longer needs location tracking after completing a task, they can actively cancel it to avoid meaningless location uploads and battery consumption.

[0067] When the device is not in the continuous positioning mode, it can enter the standby state, thus saving power and resources and extending the device's usage time. Only when the user needs it will it enter the state of regularly uploading location information. In this way, it can maintain real - time tracking without wasting battery. In the continuous positioning mode, the device only uploads location information at regular intervals, avoiding continuous data transmission, ensuring the timeliness of data and optimizing energy consumption.

[0068] In cases where it is necessary to monitor the user's activities, the continuous positioning mode can ensure that the background management personnel or guardians can always know the user's location. For example, for the elderly, children or special groups, it can ensure real - time knowledge of their location, timely detect abnormalities and take actions. Suitable for situations where the user's activities change both spatially and temporally, continuous positioning can effectively track the user's movement trajectory, especially during long - term outings, travels or adventures, providing dynamic and continuous security guarantees.

[0069] Continuous positioning enables the device to update location information in real time, providing accurate data support for emergencies.
