Description

Technical Field

[0001] This invention relates to the field of temperature measurement and positioning technology, specifically a wearable temperature measurement device and its data retrieval system. Background Technology

[0002] Body temperature refers to the internal temperature of the human body. Normal axillary temperature is 36-37 degrees Celsius. Traditional glass thermometers for measuring body temperature are typically made by filling a very thin glass tube with mercury. They come in two types: oral and rectal. Oral thermometers are placed under the tongue or armpit for measurement, while rectal thermometers are inserted into the anus. Glass thermometers are popular due to their low price, accuracy, ease of use, and lack of power requirements. However, they are easily damaged, and if the mercury leaks out and is not cleaned properly, it can cause harm. With the rapid development of electronic technology, sensor-based electronic temperature measuring devices have gradually replaced traditional glass thermometers. These are generally handheld devices, such as forehead thermometers or electronic thermometers, and usually have a button that reads the temperature of the forehead or other skin surfaces by pressing the button. Because handheld temperature measuring devices require pressing buttons to obtain temperature values, they are inconvenient to use. As a result, more and more wearable temperature measuring devices have emerged on the market. These devices are generally made in the form of watch straps. However, since the surface temperature of human skin is generally lower than the actual body temperature, watch strap temperature measuring devices still have shortcomings in terms of accuracy.

[0003] To ensure that wearable temperature measurement devices meet the demand for accurate temperature measurement, those skilled in the art have considered that axillary temperature measurements are closest to the actual human body temperature. Therefore, wearable temperature measurement devices are designed as armpit-wrap types to directly measure axillary temperature, thus obtaining the closest possible value to the actual human body temperature. This means the electronic sensor should be placed as close as possible to the armpit to obtain the temperature reading. However, existing wearable temperature measurement devices typically integrate the antenna coil and electronic sensor onto the same circuit board. During use, because the antenna coil and electronic sensor are both close to the skin when measuring body temperature, some wireless signals are directly or indirectly blocked or absorbed by the body during wireless transmission. This affects the real-time acquisition and storage of relevant measurement data, hindering subsequent retrieval and analysis of the data, and failing to meet the need for continuous monitoring and analysis of any temperature changes. Furthermore, in hospital public areas, certain special groups, due to age or various health reasons, require 24-hour intensive care during their hospitalization. After verifying their identity information, the hospital needs to obtain their corresponding temperature measurement data and location information in real time. This allows for real-time monitoring of their health status through temperature data and real-time assurance of their life and property safety through location information, thereby improving the operational efficiency of the hospital's medical infrastructure management and optimizing medical and access security services. Therefore, those skilled in the art have improved the design of existing wearable temperature measurement devices, aiming to provide a wearable temperature measurement device and its data retrieval system to solve the problems mentioned in the background art. Summary of the Invention

[0004] The purpose of this invention is to provide a wearable temperature measurement device and its data retrieval system. This device places a temperature sensor in the armpit and an antenna for transmitting wireless signals on the periphery of the armpit, away from the skin, to obtain the actual body temperature. This minimizes the risk of wireless signal blockage or absorption during transmission, thus meeting the need for real-time acquisition and storage of relevant measurement data. Simultaneously, the data retrieval system allows system administrators to easily monitor, retrieve, and analyze users' temperature and location data in real time. For hospitals, temperature data enables real-time monitoring of patients' health, while location data ensures the safety of patients and their property, further optimizing the hospital's medical infrastructure management system and improving medical and access security services.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Example 1

[0026] Wearable temperature measurement device

[0027] Please see Figure 1 , Figure 2 and Figure 3 In this embodiment, the present invention provides a wearable temperature measuring device 100, including a first connecting strap 2, a first fixing part 4, a protective shell 5, a sensor body 6, a second fixing part 8, a second connecting strap 9, a plate-shaped antenna device 7, and a plurality of buckles 3. The protective shell 5 has an opening at the top. The first fixing part 4 and the second fixing part 8 are symmetrically installed at the upper and lower ends of the protective shell 5, respectively. The sensor body 6 is embedded in the protective shell 5. The plate-shaped antenna device 7 extends outward from the inside of the sensor body 6, penetrates the protective shell 5 and the second fixing part 8, and extends and intersects in the middle of the second connecting strap 9, and is kept away from the human skin when worn. One end of the first connecting strap 2 is provided with a first fastener 1, and the other end is detachably connected to the periphery of the first fixing part 4 through the buckle 3. One end of the second connecting strap 9 is detachably connected to the periphery of the second fixing part 8 through the buckle 3, and the other end of the second connecting strap 9 is provided with a second fastener 10. Both the first connecting strap 2 and the second connecting strap 9 are made of elastic skin-friendly fabric, and the first fastener 1 and the second fastener 10 can be fastened together. The first connecting strap 2 and the second connecting strap 9 are connected to the protective shell 5 in a detachable manner to form a strip-shaped whole. At the same time, the sensor body 6 is embedded in the protective shell 5, which facilitates removal, replacement and maintenance. The first connecting strap 2 and the second connecting strap 9 are both made of elastic and skin-friendly fabric, which can greatly increase the user's wearing comfort.

[0028] Furthermore, the aforementioned plate-shaped antenna device 7 includes a flexible protective plate 7a, a copper wire 7b, and an antenna coil 7c. Both the copper wire 7b and the antenna coil 7c are encapsulated within the flexible protective plate 7a. By encapsulating the copper wire 7b and the antenna coil 7c inside the flexible protective plate 7a, the copper wire 7b and the antenna coil 7c can be better protected from damage. Due to the good flexibility of the flexible protective plate 7a, it can be better hidden and fixed in the middle of the second connecting strap 9. When worn, the plate-shaped antenna device 7 is located outside the armpit of the human body and away from the skin, which can further reduce the blocking or absorption of wireless signals by the human body during transmission, thereby meeting people's needs for real-time acquisition and storage of relevant measurement data information.

[0029] Continue reading Figure 2 and Figure 3The aforementioned sensor body 6 includes a circular plastic shell and a square circuit board 12. The circular plastic shell includes an upper convex portion 11 and a lower concave portion 13. Several buckles 11a are fixedly provided on the outer edge of the upper convex portion 11, and several slots 13a matching the buckles 11a are provided on the outer edge of the lower concave portion 13. The upper convex portion 11 and the lower concave portion 13 are engaged in the slots 13a by the buckles 11a. The lower concave portion 13 has a bottom opening 13c, and four fixed support pillars 13b are provided around its interior. The center of each fixed support pillar 13b has a hollow threaded structure. The square circuit board 12 is a double-sided PCB board. Through holes 12a corresponding to the fixed support pillars 13b are provided at the four corners of the square circuit board 12. The square circuit board 12 is fixedly connected to the fixed support pillars 13b by bolts passing through the through holes 12a. A microcontroller 17, a memory 18, a power supply unit 15, a circuit protection unit 16, and a switch unit 14 are provided on the top surface of the square circuit board 12. A temperature sensor 19 and an antenna pad 7d are provided on the bottom surface of the square circuit board 12. The size of the top opening of the protective shell 5 and the size of the bottom opening 13c of the recess 13 are equal to the size of the temperature sensor 19. The temperature sensor 19 is located in the center of the bottom surface of the square circuit board 12 and is positioned directly opposite the armpit of the human body during use. The antenna pad 7d is located at the edge of the bottom surface of the square circuit board 12 and is fixedly connected to the plate antenna device 7 by welding. The temperature sensor 19, the plate antenna device 7, the memory 18, the power supply unit 15, the circuit protection unit 16, and the switch unit 14 are all electrically connected to the microcontroller 17. In this embodiment, the sensor body 6 is designed as a circular plastic shell structure with a buckle 11a and a slot 13a. The square circuit board 12 is fixedly installed inside the circular plastic shell by bolts. This design makes it convenient to disassemble, recycle and reuse the square circuit board 12 inside the sensor body 6 after it is worn and used, effectively improving resource utilization, thereby protecting the environment and saving production costs.

[0030] Furthermore, the power supply unit 15 is powered by a button battery with a DC 3V capacity. The selection of a small, long-lasting button battery as the power source for the power supply unit 15 ensures stable and reliable operation, meeting the operational needs of the sensor body 6 after power-on. The microcontroller 17 is a combined WIFI and Bluetooth module. By combining WIFI and Bluetooth protocols, it further enhances the wireless signal transmission performance and rapid positioning effect of the wearable temperature measurement device 100.

[0031] The working principle of the wearable temperature measurement device provided in this embodiment is as follows: First, a series of device codes corresponding one-to-one with the wearable temperature measurement device 100 are established to ensure that each device code is a globally unique code. It is consistent with the identification code on the microcontroller 17 chip module in each wearable temperature measurement device 100, ensuring the traceability of each wearable temperature measurement device 100. The above-mentioned device codes are set on the circumferential surface of the recessed part 13 of the corresponding circular plastic shell through the display method of barcode or QR code, so that the device can be connected to Bluetooth via mobile device after being powered on and used in the later stage, and realize the quick scanning and binding operation. Before powering on this device, a 3V button battery (CR1630 model) needs to be inserted into the power supply unit 15. After the battery is installed, press the switch button on the switch unit 14 (not shown in the figure). At this time, the LED indicator on the switch unit 14 (not shown in the figure) will flash once every 2 seconds, and flash three times in total to enter the power-on state, thus completing the power-on operation of the device. Then, the buckles 11a on the outer edge of the upper protrusion 11 of the circular plastic shell are correspondingly inserted into the slots 13a on the outer edge of the lower recess 13 of the corresponding circular plastic shell, completing the quick assembly of the sensor body 6 of the device. After assembly, turn on the Bluetooth switch of the mobile device and scan the code using the scanning function of the mobile device to quickly bind the wearable temperature measuring device 100, and further bind the device with the relevant information of the wearer, so that the relevant information of the wearer that needs to be queried can be accurately retrieved and analyzed through the data retrieval system later. After the above scanning and binding operation is completed, the sensor body 6 is embedded in the protective shell 5. Simultaneously, the plate-shaped antenna device 7 surrounding the sensor body 6 passes through the protective shell 5 and the second fixing part 8, extending and inserting into the middle of the second connecting strap 9. Then, the first connecting strap 2 is detachably connected to the first fixing part 4 at the upper end of the protective shell 5 via the buckle 3, and the second connecting strap 9 is detachably connected to the second fixing part 8 at the lower end of the protective shell 5 via the buckle 3. This completes the rapid assembly and information binding of the wearable temperature measuring device 100. Finally, the wearable temperature measuring device 100 is worn on the user's upper arm, i.e., connected by the fastening of the first buckle 1 and the second buckle 10, forming a closed ring around the user's upper arm. For the wearing state, please refer to [link to relevant documentation]. Figure 4At this point, the temperature sensor 19 is positioned close to and directly opposite the armpit. After powering on, the temperature sensor 19 will automatically measure armpit temperature in real time according to the system administrator's settings, obtaining a temperature value closest to that measured by the human body. This temperature value will be stored in the memory 18. Here, the system administrator can also preset the upper and lower temperature limits so that when measuring armpit temperature, the memory 18 only records temperature values ​​higher than the upper limit or lower than the lower limit, thereby improving the storage performance of the memory 18. Simultaneously, the plate-shaped antenna device 7 is inserted and fixed in the middle of the second connecting strip 9, away from the outer periphery of the armpit and away from the skin. This reduces the risk of wireless signal blockage or absorption by the body during transmission, thus meeting the need for real-time acquisition and storage of relevant measurement data.

[0033] Data retrieval system

[0034] Please see Figure 5 In this embodiment, the present invention also provides a data retrieval system for a wearable temperature measuring device, including a wearable temperature measuring device 100, a listening device 101, a bridging device 102, a data relay device 103, a cloud server 104, and a mobile terminal 105. The wearable temperature measuring device 100, the listening device 101, the bridging device 102, the data relay device 103, the cloud server 104, and the mobile terminal 105 are wirelessly networked according to Bluetooth and WIFI protocols, and are connected to each other sequentially via wireless signals 106. The wearable temperature measuring device 100 is connected according to... Figure 4The wearing method shown involves attaching the sensor body 6 to the armpit of the human body. When the system is working, the wearable temperature measuring device 100 transmits the wearer's body temperature data to the listening device 101 via wireless signal 106. The listening device 101 then sends the received body temperature data to the bridging device 102, which at this point functions as the listening device 101. The bridging device 102 simultaneously sends the received body temperature data to both the listening device 101 and the data relay device 103. The data relay device 103 then sends the received body temperature data to the cloud server 104. The server 104 pushes the received body temperature data to the mobile terminal 105. Simultaneously, the mobile terminal sends the received body temperature data to the cloud server 104. On the other hand, the wearable temperature measuring device 100 sends the user's body temperature data to the mobile terminal 105 via wireless signal 106. The mobile terminal 105 uploads the received body temperature data to the cloud server 104. The cloud server 104 then sends the body temperature data back to the mobile terminal 105. Finally, the system administrator can retrieve the user's relevant body temperature data from the cloud server 104 via the mobile terminal 105. This system uses Bluetooth and Wi-Fi protocols to wirelessly network the wearable temperature measuring device 100, the monitoring device 101, the bridging device 102, the data relay device 103, the cloud server 104, and the mobile terminal 105, thus forming a complete data retrieval system. This facilitates real-time monitoring, retrieval, and analysis of user body temperature data by system administrators, meeting the requirements for continuous monitoring and analysis of any temperature changes.

[0035] To better adapt to buildings and other locations, thereby further enhancing users' smart living quality, the aforementioned listening device 101 is a type of intelligent lighting device or intelligent door control device. Using intelligent lighting or door control devices as carriers for receiving and transmitting wireless signals allows it to better integrate into people's daily lives. In the overall layout, only the signal transmission and reception functions of the receiver need to be added to the existing hardware, completing the modification of the existing hardware. Then, through software applications, the existing hardware is made intelligent, enabling the existing lighting or door control devices to have network connectivity, signal transmission, and signal reception capabilities. The intelligent lighting or door control device can receive and transmit user body temperature and location data in real time via wireless signal 106, and this data is relayed through the aforementioned data transfer device. 103 The user's body temperature and location data are uploaded to the cloud server 104 in real time. The cloud server 104 then pushes the user's relevant data to the mobile terminal 105 in real time via wireless transmission. The data retrieval system enables system administrators to monitor, retrieve, and analyze the user's relevant data in real time. Simultaneously, for smart door control devices, a smart unlocking function can be implemented. That is, when a user passes through a designated smart door control device, if the system administrator has pre-set unlocking permissions for that smart door control device in the system, when the wearable temperature measuring device 100 sends the user's relevant information to the smart door control device via wireless signal 106, the smart door control device will immediately trigger a door lock unlocking command upon receiving the user's relevant information, thus achieving the purpose of secure access and control.

[0036] In order to facilitate the quick and easy acquisition of user information, the mobile terminal 105 includes a mobile phone and a tablet computer, and also includes a corresponding application installed on the mobile phone or tablet computer. By running the above application, the system administrator can read and update the user's relevant data information in real time.

[0037] Furthermore, in order to quickly obtain the user's location information and achieve rapid intelligent positioning, please refer to... Figure 6 By arranging the three listening devices 101 around the wearable temperature measuring device 100 in three directions, during operation, each listening device 101 will generate radio wave signals 107 around its respective periphery. The intersection of the three radio wave signals 107 is designated as region A. The wearable temperature measuring device 100 will also simultaneously send wireless signals 106 to the three listening devices 101.
