Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of wearable devices, and in particular relates to an indoor and outdoor positioning bracelet for real-time abnormal heart rate alarm. Background Art
[0002] With the development of smart wearable technology, wristbands, as portable health monitoring and positioning devices, are widely used in safety monitoring scenarios for groups such as students and the elderly. However, existing wristbands have many technical defects and cannot meet actual needs.
[0003] In terms of functional integration and coordination, existing wristbands generally suffer from functional singularity and insufficient integration. Monitoring and positioning functions are separated, and positioning technology has obvious limitations: most use a single GPS or Bluetooth beacon for positioning. GPS fails indoors and has an error of >20 meters. Bluetooth beacons require active scanning, with a delay of >5 seconds and high power consumption. This prevents medical rescuers from accurately locking the location, prolonging rescue time. Health monitoring is weak, with mainstream devices relying on a single PPG optical heart rate sensor, which has an error of up to ±15bpm during exercise and is easily affected by sweat and loose wear. Although some UWB / GPS dual-mode wristbands support positioning, their heart rate monitoring does not use medical-grade chips, resulting in large data deviations and failure to meet the YD / T4875-2024 standard, which can easily lead to misjudgments of health status.
[0004] There are multiple deficiencies in safety features. Products on the market generally lack an SOS location linkage mechanism, meaning that when an alarm is triggered, the precise location cannot be simultaneously transmitted to the guardian, severely hindering rapid rescue. There is no real-time electronic fence warning capability, and no local vibration alerts when entering a dangerous area. There is no dynamic heart rate abnormality alarm capability, and because the heart rate indicator is not dynamically determined based on the exercise status, false alarms are prone to occur. There is no audio or visual reminder mechanism, so the wearer may ignore the alarm if they do not feel the vibration, and nearby people may not notice it. There is no real-time networking function, relying on Bluetooth to connect to the mobile phone. In an emergency, it cannot directly connect to the cloud server, resulting in delayed message delivery.
[0005] There's a conflict between power consumption and system synergy. Running multiple modules in parallel results in high power consumption. A battery life of less than 24 hours when GPS, 4G, and Bluetooth are fully enabled is limited to 8 hours of continuous operation, failing to meet the needs of students, the elderly, and other groups. There's also a lack of a dynamic power consumption strategy, with no automatic switching of sampling and upload frequencies based on motion, such as resting or running. High-frequency monitoring and uploads in non-active environments increase power consumption and shorten battery life.
[0006] Therefore, further improvements are made to the above problems. Summary of the Invention
[0007] The main purpose of the present invention is to provide an indoor and outdoor positioning bracelet for real-time abnormal heart rate alarm, aiming to solve the problems of existing bracelets such as single function, insufficient positioning accuracy, inaccurate health monitoring, lack of safety functions, low data reliability, and high power consumption.
[0008] To achieve the above objectives, the present invention provides an indoor and outdoor positioning bracelet for real-time abnormal heart rate alarm, comprising a body and a quick-release card pin wristband, wherein the quick-release card pin wristband is installed on the body, wherein: The main body is provided with a main control board, and the main control board is provided with a health monitoring system, an intelligent positioning system, a dynamic strategy adjustment system, an SOS one-key alarm system, and an offline voice broadcast system, wherein: The health monitoring system works as follows: a medical-grade heart rate chip provides baseline data, a six-axis sensor corrects for motion interference, an HRV algorithm calculates stress, and a vitality value model integrates heart rate and activity levels to achieve health monitoring. When an abnormal heart rate is detected, a local sound and light alarm is triggered and a message is pushed to the cloud platform. When the step count reaches the target, a green light vibrates to remind you. The working mechanism of the intelligent positioning system is as follows: if the location is indoors and an AOA base station is detected, AOA positioning is used; if the location is indoors and an iBeacon is detected, iBeacon triangulation positioning is used; if the location is outdoor and the GPS module is turned on, the GPS module combined with the 4G module is used for auxiliary positioning; in other cases, 4G base station positioning is used. The historical trajectory is achieved by recording the location coordinates once every preset time, storing them in the SPI flash memory, and the platform generates a heat map. The dynamic strategy adjustment system includes exercise status, network status, power status, temperature status and time strategy. Among them: in terms of exercise status, the heart rate collection and data upload frequency is the first frequency when running, and the second frequency when stationary; in terms of network status, 72-hour cyclic storage is activated when the network is disconnected; when the power status is less than the preset value, GPS and Bluetooth scanning are turned off; when the temperature is greater than the preset value, the CPU frequency is reduced and non-core functions are disabled; in terms of time strategy, the schedule is linked to automatically switch to high-frequency monitoring mode during exercise; The working mechanism of the SOS one-key alarm system is as follows: the user presses and holds the SOS button for a preset time, triggering an interrupt signal to the main control board. The main control board controls the 4G module to send an alarm package containing real-time coordinates, which is encrypted and transmitted to the cloud platform. The cloud platform displays the map location and pushes a text message and location link to the preset object. The bracelet also triggers the LED red light to flash rapidly for a preset time and the speaker to sound. The working mechanism of the offline voice broadcast system is as follows: when the cloud platform sends a message, the text is converted into voice by the TTS engine and compressed into MP3 and sent through the 4G module; after the wristband receives the data packet, it is stored in the SPI flash memory and played through the speaker when it detects the non-silent state. The broadcast can be interrupted by pressing any key during playback; when the wristband is offline, the cloud platform temporarily stores the message and resends it after it is connected to the network.
[0009] As a further preferred technical solution of the above technical solution, the main control board is also equipped with an electronic fence system, which draws the geographical fence through the cloud platform and synchronizes it to the bracelet. The GPS / 4G module compares the position in real time, and the vibration module vibrates to remind when crossing the boundary.
[0010] As a further preferred technical solution of the above technical solution, the main control board is also provided with a one-key person-finding function system, which sends instructions through the cloud platform to control the bracelet to ring and the LED to flash, the speaker to beep continuously, and to stop by pressing the power button.
[0011] As a further preferred technical solution of the above technical solution, the main body is provided with a laser printing area for marking personal information.
[0012] As a further preferred technical solution of the above technical solution, the quick-release card pin wristband is arranged on both sides of the main body, and the main body is worn on the wrist by toggling the quick-release card pin wristband.
[0013] The beneficial effects of the present invention are: Breakthrough functional integration capabilities: Multiple functions (including HRV / electronic fence / voice broadcast) are integrated through the selection of medical-grade chips and IP67 sealing technology. In campus scenarios, it can replace the heart rate monitor, GPS watch, and emergency pager. In elderly care scenarios, it can realize the three-in-one function of fall detection, chronic disease monitoring, and missing person warning.
[0014] Revolutionary improvement in dynamic resource scheduling: Through the five-dimensional dynamic strategy engine, the sampling and upload frequency are dynamically adjusted according to the movement status, network, power level, etc., greatly improving battery life.
[0015] Life safety protection levels have been significantly improved: In the closed-loop response to abnormal heart rates, dynamic sampling (as fast as 1 second / time) allows detection in as fast as 3 seconds. The time from SOS trigger to the school doctor receiving location information is less than 8 seconds, significantly shortening rescue time compared to the traditional solution of >30 seconds. Regarding positioning reliability, in indoor scenarios such as gymnasiums and auditoriums, where existing solutions fail with GPS and Bluetooth accuracy exceeding 10 meters, the present invention achieves AOA positioning with 1-meter accuracy. In the event of 4G signal interruption during heavy rain or haze, 72 hours of offline trajectory storage prevents loss of connection.
[0016] Essentially improved user experience: Intelligent interaction has been upgraded, and message notifications have been optimized from traditional vibration + text (requires a mobile phone) to voice broadcast (direct reading); device status inquiries do not require connecting to the app, and voice feedback is provided through buttons (such as pressing 5 times to broadcast the RFID number); abnormality reminders have been upgraded from single vibration to a multi-level sound and light combination (light + voice + specific vibration mode).

[0020] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.
[0021] In the preferred embodiments of the present invention, those skilled in the art should note that the base station and the like involved in the present invention may be regarded as prior art.
[0022] Preferred embodiment.
[0023] like Figure 1-2 As shown, the present invention discloses an indoor and outdoor positioning bracelet for real-time abnormal heart rate alarm, comprising a body 10 and a quick-release card pin wristband 20, wherein the quick-release card pin wristband 20 is installed on the body 10, wherein: The main body 10 is provided with a main control board inside and the main control board is provided with a health monitoring system, an intelligent positioning system, a dynamic strategy adjustment system, an SOS one-key alarm system, and an offline voice broadcast system, wherein: The health monitoring system works as follows: a medical-grade heart rate chip provides baseline data, a six-axis sensor corrects for motion interference, an HRV algorithm calculates stress, and a vitality value model integrates heart rate and activity levels to achieve health monitoring. When an abnormal heart rate is detected, a local sound and light alarm is triggered and a message is pushed to the cloud platform. When the step count reaches the target, a green light vibrates to remind you. Specifically: The medical-grade heart rate chip detects heart rate values around the clock and pushes them to the cloud platform in real time. When an abnormal heart rate is detected, the local bracelet will trigger an audible and visual alarm, and the cloud platform will send an alarm notification message to family members. When the number of steps reaches the standard, the green light will vibrate to remind you. The weight of the user pre-registered on the cloud platform, combined with the number of steps, can be used to estimate the calorie value consumed by exercise. The bracelet monitors the heart rate data over a period of time, records the time interval of each heartbeat and calculates the average value, calculates the average value of the square of the difference between the time interval of each heartbeat and the mean, and finally derives the HRV index. Through HRV and the number of steps in different time periods, if the number of steps decreases after exercise and the heart rate recovers slowly, it means that you may be in a high stress state. Otherwise, the stress is low. By combining the age of different bracelet wearers with the heart rate and number of steps of daily activities, the medium and high intensity activity time is compared with the target activity time, and the vitality value can be estimated. The intelligent positioning system works as follows: If an AOA base station is detected indoors, AOA positioning is used (1-meter accuracy); if an iBeacon is detected indoors, iBeacon triangulation is used (3-meter accuracy); if the GPS module is turned on outdoors, GPS and 4G modules are used for assisted positioning (5-meter accuracy); otherwise, 4G base station positioning is used (100-meter accuracy). Historical tracking is achieved by recording location coordinates every preset time (30 seconds), storing them in SPI flash memory, and generating a heat map using the platform. The dynamic strategy adjustment system includes exercise status, network status, battery status, temperature status and time strategy. Among them: in terms of exercise status, the heart rate collection and data upload frequency is the first frequency (1 second / time) when running, and the second frequency (600 seconds / time) when stationary; in terms of network status, 72-hour cyclic storage is activated when the network is disconnected; when the battery status is less than the preset value (20%), GPS and Bluetooth scanning are turned off; when the temperature is greater than the preset value (75℃), the CPU frequency is reduced (to 80MHz) and non-core functions are disabled; in terms of time strategy, the schedule (such as the class schedule) is linked to automatically switch to high-frequency monitoring mode during exercise; The working mechanism of the SOS one-key alarm system is as follows: the user presses and holds the SOS button for a preset time (3 seconds), triggering an interrupt signal to the main control board. The main control board controls the 4G module to send an alarm package containing real-time coordinates, which is encrypted and transmitted to the cloud platform. The cloud platform displays the location on the map and simultaneously pushes a text message and location link to the preset recipient (such as a parent). The bracelet also triggers the LED red light to flash rapidly for a preset time (3 seconds) and the speaker to speak (help has been sent). The working mechanism of the offline voice broadcast system is as follows: when the cloud platform sends a message, the text is converted into voice by the TTS engine and compressed into MP3 and sent through the 4G module; after the wristband receives the data packet, it is stored in the SPI flash memory and played through the speaker when it detects the non-silent state. The broadcast can be interrupted by pressing any key during playback; when the wristband is offline, the cloud platform temporarily stores the message and resends it after it is connected to the network.
[0024] Specifically, the main control board is also equipped with an electronic fence system, which draws a geographical fence through the cloud platform and synchronizes it to the bracelet. The GPS / 4G module compares the position in real time, and the vibration module vibrates to remind when the boundary is crossed.
[0025] More specifically, the main control board is also equipped with a one-button person-finding function system, which sends instructions through the cloud platform to control the bracelet to ring and the LED to flash, the speaker to beep continuously, and to stop by pressing the power button.
[0026] Furthermore, the body 10 is provided with a laser printing area for marking personal information.
[0027] Furthermore, the quick-release card pin wristband 20 is set on both sides of the main body 10. The wristband 20 is removed by turning the quick-release card pin and the main body 10 is worn on the wrist.
[0028] For the present invention: Taking the student physical education class scenario as an example, the complete workflow is as follows: Step 1: Preparation before class. The charging box automatically detects the bracelet version and downloads the incremental package to upgrade the firmware. Step 2: During class monitoring, the student's exercise status is identified as running (cadence 150 steps / minute), and the "fast running" status is marked. The dynamic strategy activates heart rate collection every second (using a medical-grade chip) and data upload every second (4G direct connection). When the heart rate is detected to be greater than 190bpm, the local trigger is a solid red light and a voice message "abnormal heart rate" is displayed. The platform pops up a window to the school doctor's terminal and displays the location (east area of the playground). Step 3: After class analysis, the cloud platform generates a report including exercise duration and calorie consumption.
