Description

Technical Field

[0001] The present invention relates to the field of smart bracelets, and particularly to a heatstroke prevention warning smart bracelet and its warning method. Background Art

[0002] For outdoor workers such as construction workers, couriers, and traffic policemen, they are exposed to high-temperature environments for a long time and are extremely prone to heatstroke. A heatstroke prevention warning device can monitor their physical conditions in real time. Once there is a risk of heatstroke, it can timely remind them to rest, replenish water, etc., effectively reducing the incidence of heatstroke accidents and ensuring their physical health and life safety. Current heatstroke prevention warning devices include sweat monitors, smart bracelets, head-mounted monitoring devices, etc. Regarding smart bracelets, in the prior art, the body surface temperature sensor and the ambient temperature sensor in the smart bracelet are not heat-insulated, and heat will be transferred between the two sensors, resulting in inaccurate collected data. Moreover, most of the current heatstroke prevention warning devices on the market adopt fixed alarm thresholds, without fully considering the individual physiological differences of users and the influence of environmental factors on the human body temperature, which easily leads to false alarms or missed alarms. Summary of the Invention

[0003] The purpose of the present invention is to provide a heatstroke prevention warning smart bracelet to solve the above problems. By real-time monitoring and analysis of the user's body temperature and environmental data, the alarm threshold is dynamically adjusted to achieve accurate classification warning of heatstroke risk, and intelligent medication reminder and personalized setting functions are provided to improve the accuracy of warning and the user experience.

[0004] The present invention realizes the above purpose through the following technical solutions:

[0005] The present invention provides a heatstroke prevention warning smart bracelet, including an upper cover, a middle frame, and a bottom cover. The middle frame is fixedly connected to the bottom cover, the upper cover is snap-fitted on the middle frame. The bottom of the bottom cover is provided with a body surface temperature sensor, and the side of the bottom cover is provided with an ambient temperature sensor. A first heat-insulating structure is provided on the periphery of the body surface temperature sensor, and a second heat-insulating structure is provided on the periphery of the ambient temperature sensor;

[0006] A main board is arranged between the middle frame and the upper cover, and a buzzer is arranged between the main board and the upper cover; the ambient temperature sensor is arranged on a side of the bottom cover that can fully contact the air, and the position of the ambient temperature sensor is close to the upper part of the bottom cover; the body surface temperature sensor is arranged at the middle position of the bottom of the bottom cover;

[0007] The other side of the side of the bottom cover where the ambient temperature sensor is located is connected to a medicine bin. The medicine bin is arranged along the length direction of the smart bracelet, and the outside of the medicine bin is arc-shaped; the medicine bin is provided with two medicine outlets, which are respectively located on the front and back sides of the medicine bin.

[0008] As a preferred technical solution of this case, the first heat insulation structure is arranged inside the installation position of the ambient temperature sensor;

[0009] The first heat insulation structure includes a heat insulation installation groove surrounded by multiple heat insulation plates, and the ambient temperature sensor is installed in the heat insulation installation groove to isolate the ambient temperature sensor.

[0010] As a preferred technical solution of this case, an installation hole is opened in the lower part of the bottom cover, and the body surface temperature sensor is installed at the position of the installation hole;

[0011] The second heat insulation structure includes a heat insulation pad, and the heat insulation pad is installed around the circumference of the body surface temperature sensor and fixes the body surface temperature sensor.

[0012] As a preferred technical solution of this case, an indicator light is installed on the upper cover, and a speaker hole is opened on the upper cover corresponding to the position of the buzzer.

[0013] As a preferred technical solution of this case, a battery and a vibration motor are arranged inside the bottom cover, and the vibration motor is installed in the motor installation groove; a magnetic charging component is arranged at the bottom of the bottom cover, and the magnetic charging component is connected to the battery.

[0014] As a preferred technical solution of this case, switch sensors are arranged at both medicine outlets of the medicine bin.

[0015] The present invention also provides a warning method for a heatstroke prevention warning bracelet, including the following steps:

[0016] S1: Data collection and processing, using the body surface temperature sensor to collect the body surface temperature data T at the wrist in real time 体表 , and collecting the surrounding ambient temperature data ambient T in real time through the ambient temperature sensor 环境 , with a collection frequency of once every 5 seconds; using a temperature compensation algorithm to calculate the core body temperature core body surface ambient T 核心 =a×T 体表 +b×T 环境 +c. The algorithm of this formula improves the accuracy of heatstroke risk judgment and reduces misjudgment caused by simply relying on body surface temperature or ambient temperature. Among them, a, b, and c are coefficients obtained by fitting according to experimental data;

[0017] S2: Alarm threshold setting and dynamic adjustment, setting the initial mild heatstroke warning threshold warning low T 预警低 =37.5°C, and the severe heatstroke warning threshold warning high T 预警高 =38.5°C; and dynamically adjusting the alarm threshold based on the user's historical core body temperature data and ambient temperature data, as well as machine learning algorithms;

[0018] S3: Heatstroke risk grading. When T 预警低 ≤T 核心 <T 预警高 it is determined as a mild heatstroke risk, and an audible, visual, and vibration alarm method is adopted; when T 核心 ≥T 预警高 it is determined as a severe heatstroke risk, and a more intense audible, visual, and vibration alarm method is adopted, and an emergency distress message is sent to the user's mobile phone;

[0019] S4: When the warning is triggered, detect the remaining amount of medicine in the medicine warehouse and give a medicine reminder according to the risk level.

[0020] Furthermore, the method for adjusting the alarm threshold based on the user's historical core body temperature data is as follows: calculate the historical average value of the user's core body temperature in the past week If increase T 预警低 by 0.2°C and T 预警高 by 0.3°C; if T 预警高 ≤36.5°C, decrease T 预警高 by 0.1°C and T 预警高 by 0.2°C;

[0021] The method for adjusting the alarm threshold in combination with the historical ambient temperature data is as follows: calculate the historical average value of the ambient temperature of the user in the past week When is greater than or equal to 30°C, the mild heatstroke warning threshold T 预警低 is increased by 0.1 - 0.3°C, and the severe heatstroke warning threshold T 预警高 is increased by 0.2 - 0.4°C; when the mild heatstroke warning threshold T 预警低 is increased by 0.1 - 0.2°C, and the severe heatstroke warning threshold T 预警高 is increased by 0.2 - 0.3°C.

[0022] Furthermore, the alarm method for mild heatstroke risk is as follows: the buzzer emits a low-frequency short beep, that is, the frequency is 500 Hz, the duration is 0.5 seconds, the interval is 1 second, the indicator light flashes yellow, the flashing frequency is 1 time per second, and the vibration motor vibrates slightly, that is, the vibration intensity is level 3, the duration is 0.5 seconds, and the interval is 1 second;

[0023] The alarm method for severe heatstroke risk is as follows: the buzzer emits a high-frequency long beep, that is, the frequency is 1000 Hz, the duration is 1 second, the interval is 0.5 seconds, the indicator light flashes red, the flashing frequency is 2 times per second, and the vibration motor vibrates strongly, the vibration intensity is level 5, the duration is 1 second, and the interval is 0.5 seconds.

[0024] Further, the drug reminder method for the medicine bin is as follows: in case of low risk, it reminds once every 5 minutes. The reminder method is the vibration of the vibration motor, i.e., the intensity is level 2, the duration is 0.3 seconds, the indicator light flashes green, and the flashing frequency is 0.5 times per second; in case of high risk, it reminds once every 1 minute. The reminder method is the vibration of the vibration motor, the intensity is level 4, the duration is 0.5 seconds, and the indicator light flashes green rapidly, with a flashing frequency of 1 time per second. The medicine discharging control method for the medicine bin is as follows: the medicine bin is provided with two medicine discharging ports. The switch sensors at the medicine discharging ports are used to detect the user's medicine taking situation and record the medicine taking time and dosage. The drug effect is judged according to the decrease amplitude of the core body temperature within 30 minutes after taking the medicine. If the decrease amplitude is less than 0.5 °C, the user is reminded to take the medicine again.

[0025] The beneficial effects are as follows: by arranging the first heat insulation structure and the second heat insulation structure at the installation positions of the ambient temperature sensor and the body surface temperature sensor, the heat transfer between the two sensors can be avoided, and the accuracy of data collection can be improved. At the same time, a medicine bin is arranged on the inner side of the bracelet, i.e., the side close to the hand when wearing the bracelet. The medicine bin can be filled with heatstroke prevention medicine. When the bracelet gives an alarm, the user can open the medicine bin and directly pour the heatstroke prevention medicine into the mouth, which can relieve the symptoms of heatstroke. By dynamically adjusting the alarm threshold, fully considering the individual differences of users and environmental factors, the accuracy of heatstroke warning is improved, and the occurrence of false alarms and missed alarms is reduced.

[0037] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other implementation manners obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0038] See Figures 1 - 8 As shown, the present invention provides a heat - stroke prevention warning bracelet, including an upper cover 1, a middle frame 2 and a bottom cover 3. The middle frame 2 is fixedly connected to the bottom cover 3, the upper cover 1 is snap - fitted on the middle frame 2, a body surface temperature sensor 10 is provided at the bottom of the bottom cover 3, an ambient temperature sensor 6 is provided on the side surface of the bottom cover 3, and a first heat - insulation structure 14 is provided on the periphery of the body surface temperature sensor 10, and a second heat - insulation structure 15 is provided on the periphery of the ambient temperature sensor 6; a main board 5 is arranged between the middle frame 2 and the upper cover 1, and a buzzer 11 is arranged between the main board 5 and the upper cover 1.

[0039] In the above - mentioned solution, the body surface temperature sensor 10 can dynamically collect the body surface temperature in real time, and the ambient temperature sensor 6 can dynamically collect the ambient temperature in real time. The collected ambient temperature and body surface temperature data are compensated by a built - in algorithm for a certain temperature, and then the core body temperature is calculated. When the calculated core body temperature reaches or exceeds the corresponding alarm threshold, the product will issue a heat - stroke warning to remind the personnel working in a high - temperature environment to pay attention to their own physical conditions.

[0040] As a preferred embodiment of this case, refer to Figure 2As shown, the ambient temperature sensor 6 is disposed on a side surface of the bottom cover 3 where it can be in full contact with air, and the position of the ambient temperature sensor 6 is close to the upper part of the bottom cover 3. This position selection helps it better contact the surrounding ambient air, so as to accurately obtain ambient temperature data. The body surface temperature sensor 10 is disposed at the middle position of the bottom of the bottom cover 3. The positions of the ambient temperature sensor 6 and the body surface temperature sensor 10 are set such that the distance between the two sensors 6 becomes farther, reducing the influence of heat transfer.

[0041] Further, referring to Figure 7 As shown, the first heat insulation structure 14 is disposed inside the installation position of the ambient temperature sensor 6; the first heat insulation structure 14 includes a heat insulation installation groove surrounded by multiple heat insulation plates, and the ambient temperature sensor 6 is installed in the heat insulation installation groove to isolate the ambient temperature sensor 6. This structure can block the transfer of heat and avoid the influence of heat transfer between the two sensors 6 on the acquisition accuracy.

[0042] Referring to Figure 7 As shown, an installation hole is formed in the lower part of the bottom cover 3, and the body surface temperature sensor 10 is installed at the position of the installation hole; the second heat insulation structure 15 includes a heat insulation pad, and the heat insulation pad is installed around the circumference of the body surface temperature sensor 10 and fixes the body surface temperature sensor 10. The heat insulation pad is made of heat insulation silica gel, which can reduce the heat transfer of the body surface temperature sensor 10.

[0043] Further, as an optional implementation manner of this case, an indicator light 9 is installed on the upper cover 1, and a speaker hole 8 is formed in the upper cover 1 corresponding to the position of the buzzer 11. A battery 4 and a vibration motor 7 are disposed inside the bottom cover 3, and the vibration motor 7 is installed in a motor installation groove. When the calculated core body temperature reaches or exceeds the corresponding alarm threshold, the buzzer 11 and the vibration motor 7 will give an alarm. At the same time, when the ambient temperature is too high, the indicator light 9 flashes yellow, and when the body temperature is too high, it flashes red.

[0044] Referring to Figure 6 As shown, a magnetic charging component 13 is disposed at the bottom of the bottom cover 3, and the magnetic charging component 13 is connected to the battery 4. The battery 4 supplies power to the main board 5, the buzzer 11, the vibration motor 7, the body surface temperature sensor 10, and the ambient temperature sensor 6. And a switch button 12 is disposed on the side of the middle frame 2, and the switch button 12 is connected to the main board 5 and can control the switch of the bracelet.

[0045] As an optional implementation manner of this case, referring to Figure 7 and Figure 8As shown, a medicine bin 16 is connected to the other side of the side surface of the bottom cover 3 where the ambient temperature sensor 6 is located. The medicine bin 16 can hold medicine. When the bracelet gives an alarm, the user can open the medicine bin 16 and directly pour the heat-relieving medicine into the mouth, which can relieve the symptoms of heatstroke.

[0046] Furthermore, the medicine bin 16 is arranged along the length direction of the bracelet, and the outside of the medicine bin 16 is arc-shaped; the medicine bin 16 is provided with two medicine outlets 1601, which are respectively located on the front and back sides of the medicine bin 16. By setting two medicine outlets 1601, the lower medicine outlet 1601 is for the user to pour the medicine into the mouth just by raising the hand during use, which is more convenient. The upper medicine outlet 1601 is for quickly pouring out the medicine for others to use. The medicine outlet 1601 is configured with a lid. Switch sensors are provided at both medicine outlets of the medicine bin, which can detect the user's medication situation.

[0047] The present invention also provides a warning method for a heatstroke prevention warning bracelet, including the following steps:

[0048] S1: Data collection and processing, using the body surface temperature sensor to collect the body surface temperature data T at the wrist in real time 体表 , and using the ambient temperature sensor to collect the ambient temperature data ambient T around in real time 环境 , with the collection frequency being once every 5 seconds; using the temperature compensation algorithm to calculate the core body temperature core body surface ambient T 核心 =a×T 体表 +b×T 环境 +c. The algorithm of this formula improves the accuracy of heatstroke risk judgment and reduces misjudgment caused by simply relying on body surface temperature or ambient temperature. Among them, a, b, and c are coefficients obtained by fitting according to experimental data; the value range of a is approximately between 0.6 and 0.8. For example, when a takes 0.7, it means that the body surface temperature accounts for a relatively large weight in the calculation of the core body temperature. The value range of b is usually between 0.1 and 0.3. Although the ambient temperature also affects the human body temperature, relatively speaking, its influence degree is smaller than that of the body surface temperature, so the value of b is relatively small. For example, b = 0.1, indicating that the ambient temperature has a relatively low weight in the calculation of the core body temperature. c is a constant term, and its value range may be between 3 and 6 °C. It is mainly used to correct the formula to compensate for the influence of other factors not considered on the calculation of the core body temperature. Optionally, c = 5. After comprehensively considering the body surface temperature and the ambient temperature, a fixed compensation value can be added to calculate the core body temperature more accurately. This step can obtain key data closely related to heatstroke risk. The body surface temperature can reflect the heat dissipation situation on the human body surface, and the ambient temperature reflects the external thermal environment where the human body is located. High-frequency collection can ensure the timeliness and continuity of the data and capture the subtle changes in body temperature and ambient temperature.

[0049] S2: Alarm threshold setting and dynamic adjustment, set the initial mild heatstroke warning threshold Warning Low T 预警低 = 37.5 °C, and the severe heatstroke warning threshold Warning High T 预警高 = 38.5 °C; and dynamically adjust the alarm threshold based on the user's historical core body temperature data, environmental temperature data, and machine learning algorithms; considering the individual differences in the basal body temperatures of different users, by analyzing the user's own historical body temperature data, the alarm threshold is made more suitable for the user's actual physical condition, avoiding false alarms or missed alarms caused by individual differences, greatly improving the accuracy of early warning. For users with higher or lower basal body temperatures, it can provide early warning services more in line with their physical characteristics, enhancing the personalization and applicability of the smart bracelet.

[0050] S3: Heatstroke risk grading. When T 预警低 ≤ T 核心 < T 预警高 it is determined as a mild heatstroke risk, and an audible, visual, and vibration alarm method is adopted; when T 核心 ≥ T 预警高 it is determined as a severe heatstroke risk, and a more intense audible, visual, and vibration alarm method is adopted, and an emergency SOS message is sent to the user's mobile phone; when mild heatstroke occurs, it enables the user to promptly detect the mild heatstroke risk and have enough time to take measures such as replenishing water and resting in a cool place, reducing the possibility of developing into severe heatstroke. When the user is at risk of severe heatstroke, through a strong audible, visual, and vibration alarm and sending an emergency SOS message, it quickly attracts the attention of the user and surrounding people, enabling timely first aid measures to be taken, ensuring the user's life safety, and greatly improving the emergency response speed in the case of severe heatstroke.

[0051] S4: When the early warning is triggered, detect the remaining amount of drugs in the medicine compartment and give a medication reminder according to the risk level.

[0052] Furthermore, the method for adjusting the alarm threshold based on the user's historical core body temperature data is as follows: calculate the historical average value of the user's core body temperature in the past week If raise T 预警低 by 0.2 °C and T 预警高 by 0.3 °C; if T 预警高 ≤ 36.5 °C, lower T 预警高 by 0.1 °C and T 预警高 by 0.2 °C;

[0053] The method for adjusting the alarm threshold in combination with the historical environmental temperature data is as follows: calculate the historical average value of the environmental temperature in the past week for the user When is greater than or equal to 30 °C, the mild heatstroke warning threshold T 预警低 is raised by 0.1 - 0.3 °C, and the severe heatstroke warning threshold T 预警高Increase by 0.2 - 0.4 °C; when When, the warning threshold T for mild heat stroke 预警低 Increase by 0.1 - 0.2 °C, and the warning threshold T for severe heat stroke 预警高 Increase by 0.2 - 0.3 °C. Adjusting the alarm threshold according to the historical average value of the ambient temperature can make the warning more adaptable to environmental changes, avoid misjudgment caused by environmental factors. This method effectively reduces the occurrence of false alarms and missed alarms in high or low temperature environments, and improves the warning accuracy and reliability of the bracelet under different environmental conditions.

[0054] Furthermore, the alarm method for mild heat stroke risk is as follows: the buzzer emits a low-frequency short beep, that is, the frequency is 500 Hz, the duration is 0.5 seconds, the interval is 1 second, the indicator light flashes yellow, the flashing frequency is 1 time per second, and the vibration motor vibrates slightly, that is, the vibration intensity is level 3, the duration is 0.5 seconds, and the interval is 1 second;

[0055] The alarm method for severe heat stroke risk is as follows: the buzzer emits a high-frequency long beep, that is, the frequency is 1000 Hz, the duration is 1 second, the interval is 0.5 seconds, the indicator light flashes red, the flashing frequency is 2 times per second, and the vibration motor vibrates strongly, the vibration intensity is level 5, the duration is 1 second, and the interval is 0.5 seconds.

[0056] Furthermore, the medicine reminder method for the medicine bin is as follows: in the case of mild risk, remind once every 5 minutes, and the reminder method is that the vibration motor vibrates, that is, the intensity is level 2, the duration is 0.3 seconds, and the indicator light flashes green, the flashing frequency is 0.5 times per second; in the case of severe risk, remind once every 1 minute, and the reminder method is that the vibration motor vibrates, the intensity is level 4, the duration is 0.5 seconds, and the indicator light flashes green quickly, the flashing frequency is 1 time per second; the medicine discharging control method for the medicine bin is as follows: the medicine bin is provided with two medicine discharging ports, and the switch sensors at the medicine discharging ports are used to detect the user's medicine taking situation, record the medicine taking time and dosage; judge the drug effect according to the decrease range of the core body temperature within 30 minutes after taking the medicine. If the decrease range is less than 0.5 °C, remind to take the medicine again. Specifically, when it is detected that the user manually opens the lower medicine discharging port (detected by the switch sensor at the medicine discharging port), record the medicine taking time and dosage (assuming that the amount of medicine taken each time is a fixed value in grams); if it is detected that the upper medicine discharging port is opened, record the relevant information in the same way. Analyze the drug effect according to the medicine taking record and the change of the user's core body temperature. If the user's core body temperature decreases by less than 0.5 °C within 30 minutes after taking the medicine, remind the user to take the medicine again or suggest seeking medical help.

[0057] As described above, it is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the said claims.
