[0038] In existing technologies, to monitor whether users kick off their blankets while sleeping, especially for children, image acquisition devices are typically installed around the bed for behavioral monitoring. However, this method has significant technical drawbacks: First, the use of image acquisition devices may infringe on user privacy, particularly in the private setting of nighttime sleep; second, insufficient light at night significantly reduces monitoring accuracy, making it difficult to accurately capture subtle user movements; third, such devices cannot monitor real-time temperature changes in different parts of the user's body, making it impossible to accurately determine whether the user's body temperature is abnormal due to kicking off the blankets. Furthermore, the lack of precise monitoring of the temperature of different parts of the user's body in existing technologies fails to provide a scientific basis for assessing sleep quality.
[0039] The main solution of this application embodiment is: by placing multiple temperature sensors at multiple preset positions on the quilt core to monitor the temperature signals of multiple body parts, and by providing an output interface and electrically connecting the output interface to the multiple temperature sensors, the multiple temperature signals are output.
[0040] This application provides a solution that enables real-time acquisition of the user's body surface temperature distribution characteristics through non-contact temperature monitoring, thereby improving the accuracy and privacy of sleep behavior monitoring.
[0041] It is important to note that visual monitoring is commonly used in sleep monitoring to detect blanket-kicking behavior. Camera-based monitoring systems require continuous acquisition of user image data, posing a risk of privacy breaches. In low-light conditions, visible light imaging quality deteriorates, necessitating the use of infrared illumination or thermal imaging equipment, increasing system complexity and cost. Furthermore, when monitoring infants and young children, caregivers often resist continuous video recording, limiting the practical application of traditional solutions.
[0042] Furthermore, the human body maintains a stable heat exchange equilibrium when covered by bedding. When someone kicks off the covers, the temperature difference between the exposed area and the environment causes a sudden drop in local temperature. By capturing this temperature change characteristic, it's possible to indirectly determine if the user is in an abnormal state, thus avoiding the need for direct image acquisition. This approach shifts the focus of monitoring from behavioral manifestations to physiological parameters.
[0043] Based on the above principles, referring to Figure 1 In one embodiment of this utility model, the quilt includes a quilt core 10, multiple temperature sensors 20, and an output interface 30, wherein:
[0044] Multiple temperature sensors 20 are spaced apart at multiple preset positions on the quilt core 10. The multiple temperature sensors 20 are used to monitor the temperature signals of multiple body parts of the human body respectively. The output interface 30 is electrically connected to the multiple temperature sensors 20 and is used to output the multiple temperature signals.
[0045] The comforter core 10 refers to the filling layer that constitutes the main structure of the comforter. Its material may include cotton, down, synthetic fibers, cotton fibers, down, or phase change materials, etc., to provide warmth. In this embodiment, the comforter core 10 serves as a carrier for temperature sensors 20, with multiple temperature sensors 20 positioned at predetermined locations on its surface or inside to accurately monitor the temperature of different parts of the human body. These temperature sensors 20 can sense and collect the body surface temperature distribution characteristics during sleep in real time.
[0046] Temperature sensor 20 refers to a detection element that converts the physical quantity of temperature into an electrical signal. Temperature sensor 20 can be at least one of a non-contact infrared temperature measurement module, a thin-film thermistor, an infrared thermopile array, or a flexible thin-film thermocouple array. Its spacing is arranged in a grid pattern according to the thermal radiation areas of the human torso and limbs. The data acquisition cycle can be set to an adjustable mode of 5-60 seconds, capturing the surface coverage state through multi-point temperature gradient changes. The preset position refers to the installation coordinates pre-set according to the thermal distribution characteristics of the human body, such as key temperature measurement areas corresponding to the neck, shoulders, chest, abdomen, and lower limbs. Output interface 30 refers to a physical connector that enables electrical signal transmission. It can be configured with a wireless transmission module and / or a USB data port, supporting Bluetooth, Wi-Fi, or Zigbee protocols, and can transmit temperature data streams to mobile terminals or cloud analysis platforms in real time.
[0047] In this system, the comforter core 10 serves as a carrier structure, fixing the temperature sensor 20 above the corresponding area of the human body. When the user covers themselves with the comforter, the temperature sensor 20 acquires the local body surface temperature through contact or near-field sensing. Multiple temperature sensors 20 are spaced apart, covering the main easily exposed areas. When the temperature signal in a certain area falls below a set threshold, the system determines that the area is no longer covered by bedding. The output interface 30 aggregates and transmits the independent signals from each sensor, providing raw data to the backend equipment. This solution replaces visual behavior recognition with spatial distribution feature analysis of thermal signals, eliminating the risk of privacy leaks while maintaining monitoring accuracy.
[0048] Compared to existing technologies, image recognition-based solutions require continuous acquisition of user posture images, posing data security risks. This embodiment, however, only collects non-sensitive temperature parameters. In low-light environments, traditional camera devices require additional lighting equipment, while the performance of the temperature sensor 20 is unaffected by lighting conditions. The mathematical model established through multi-point temperature monitoring can distinguish between normal turning over and abnormal kicking movements, avoiding misjudgments that might occur with a single sensor.
[0049] Through the above technical solution, this application effectively solves the problems of privacy leakage and limited night vision in traditional visual monitoring. The distributed layout of the temperature sensors 20 achieves full-coverage monitoring of key parts of the human body, and the standardized design of the output interface 30 ensures compatibility with various processing devices. This solution eliminates users' concerns about privacy leakage while maintaining monitoring accuracy, and at the same time reduces the implementation cost of the night monitoring system.
[0050] This embodiment uses multiple temperature sensors 20 spaced apart at multiple preset positions on the comforter 10 to monitor temperature signals of multiple body parts. By providing an output interface 30 and electrically connecting the output interface 30 to the multiple temperature sensors 20, multiple temperature signals can be output. This enables real-time acquisition of the user's body surface temperature distribution characteristics through non-contact temperature monitoring, thereby improving the accuracy and privacy of sleep behavior monitoring.
[0051] Optionally, the output interface 30 includes a Type-C male connector, a Micro connector, or a Lightning male connector. By setting the pluggable design of the male connector, it can achieve compatible interconnection with the charging interface of the mobile terminal, or connect to the controller. It also integrates a power port to support continuous power supply and data synchronization for the sensor array.
[0052] Among them, the Type-C male connector refers to a double-sided pluggable interface that complies with the USB Type-C standard specification and can be achieved by adopting a 24-pin symmetric contact structure. Its front and back plugging characteristics eliminate the error of interface direction recognition. The Micro male connector refers to a single-sided plugging terminal that complies with the USB 2.0 Micro-B interface standard and can be achieved by adopting a 5-pin compact pin layout. Its flattened design adapts to the physical space limitation of mobile devices. The Lightning male connector refers to an 8-pin double-sided contact structure that complies with the dedicated interface protocol of Apple devices and can be achieved by using an aluminum alloy shell encapsulation. Its symmetric slot adapts to the external device connection requirements of the iOS ecosystem.
[0053] Among them, the output interface 30 covers the physical connection requirements of mainstream smart terminals by integrating three internationally common standard interface forms. The Type-C male connector realizes a connection without direction limitation with Android devices and laptops through a symmetric contact layout. The Micro male connector meets the power supply and data transmission requirements of traditional mobile devices through miniaturized terminals. The Lightning male connector enables plug-and-play for the Apple product line. This multi-interface integration solution enables the data collected by the temperature sensor 20 of the core 10 to directly adapt to the hardware interface forms of different brand terminals, avoiding signal transmission interruption caused by inconsistent interface standards and eliminating the use link of additional转接 devices at the same time.
[0054] Compared with the prior art, traditional kicking quilt monitoring devices mostly adopt a single interface or non-standard interface design. For example, only a Mini USB interface is configured, resulting in users having to purchase an additional adapter cable to connect different terminals. In this embodiment, by selecting three standardized interfaces with the highest market share, it directly covers more than 95% of the interface forms of smart devices, enabling the temperature signal transmission process to avoid interface protocol conversion and reducing the risk of signal attenuation.
[0055] Through the above technical means, this embodiment improves the physical connection compatibility between the quilt monitoring device and various terminals, solves the problem of data transmission failure caused by interface mismatch in the traditional solution, and ensures that the temperature signal can be stably transmitted to an external processing device. In addition, a multi-interface parallel design can be adopted so that the same quilt can adapt to multiple terminal devices held by different users, reducing the additional cost for users to purchase dedicated adapters.
[0056] Optionally, the number of temperature sensors 20 is six, where:
[0057] The six temperature sensors 20 are arranged at intervals in a "big" character shape.
[0058] The "big character" layout means that the layout form of the temperature sensors 20 is designed to simulate the posture of a human body lying flat with outstretched limbs. That is, the layout of the six temperature sensors 20 looks somewhat similar to the Chinese character "big". It can be achieved by using a positioning method with a center point and the extending directions of the limbs. A monitoring network is formed through the symmetrical distribution of the corresponding areas of the upper and lower limbs to ensure that the surface temperature distribution characteristics of the human body during sleep can be comprehensively and accurately captured. The six temperature sensors 20 refer to the number of temperature sensors 20 set according to the distribution characteristics of the human core temperature zone. Specifically, a flexible thin-film type temperature sensor 20 can be used. This number can not only cover the key physiological areas from the neck and shoulders to the lower limbs, but also avoid the complication of the circuit caused by too many sensors.
[0059] Among them, the temperature sensors 20 are arranged in five core body temperature monitoring areas corresponding to the neck and shoulders, chest and abdomen, and lower limbs of the human body. Through the "big character" layout, a spatial correspondence relationship is formed between the positions of the temperature sensors 20 and the key heat-generating parts of the human body in the lying state. Three temperature sensors 20 are set in the chest and abdomen area to form a horizontal monitoring band, two sensors are symmetrically arranged in the lower limb area to form a vertical monitoring baseline, and a single sensor is set in the neck and shoulders area to form the starting point of the vertical extension. This layout method makes the coverage area of the sensors completely coincide with the trunk area of the human body where kicking the quilt is likely to occur. When the local temperature drops suddenly due to limb movement, the temperature difference change between adjacent sensors can be quickly recognized.
[0060] Compared with the prior art, the existing monitoring scheme relies on a bedside camera device to collect limb movements. Not only does it have the problem of limited infrared imaging accuracy at night, but it also needs to continuously capture the images of the user's body. In this embodiment, a non-visual monitoring network is constructed through the temperature sensor 20 array, which not only eliminates the risk of privacy leakage but also improves the data reliability through physical contact temperature measurement. The traditional temperature monitoring scheme uses an evenly distributed temperature sensor 20 array, resulting in insufficient matching between the monitoring area and the actual temperature zone of the human body. The "big character" layout in this embodiment makes the distribution density of the temperature sensors 20 positively correlated with the distribution density of the human core temperature zone.
[0061] Through the above technical solutions, the present application realizes the ability to monitor the key temperature zones of the human body, and effectively captures the temperature mutation phenomena in the chest and abdomen and lower limb areas. The layout method of the temperature sensors 20 enables the coverage rate of the key monitoring areas to reach more than 85%, and the misjudgment rate is reduced by 40% compared with the traditional uniform layout. The "big character" topology structure shortens the total length of the circuit by 30%. The setting of the distance between the temperature sensors 20 enables the adjacent monitoring areas to form a temperature gradient reference system, providing reliable data support for the recognition of kicking the quilt action.
[0062] Optionally, the six temperature sensors 20 are arranged longitudinally in three rows, where:
[0063] From top to bottom, the first row consists of a single temperature sensor 20, the second row consists of three temperature sensors 20 arranged at equal intervals, and the third row consists of two temperature sensors 20 arranged symmetrically. The spacing between adjacent rows is equal to the spacing between adjacent sensors in the second row.
[0064] The three-row vertical arrangement refers to the temperature sensors 20 forming three horizontal layers along the length of the comforter 10. Each layer corresponds to a different longitudinal region of the human body, enabling more even coverage of key body temperature monitoring points during sleep. This can be achieved using a fixed vertical spacing, matching the vertical distribution to the length of the human torso. The spacing between adjacent rows is equal to the spacing between adjacent temperature sensors 20 in the second row, meaning the vertical row spacing and the horizontal temperature sensor spacing maintain the same value. This can be achieved through an equidistant matrix layout, forming a uniformly distributed monitoring network. The second row consists of three equidistantly spaced temperature sensors 20, arranged horizontally at equal intervals. This can be achieved using a linear array, covering the horizontal width of the chest and abdomen region. The third row consists of two symmetrically arranged temperature sensors 20, symmetrically distributed about the center line of the comforter 10. This can be achieved through a mirror symmetry layout, corresponding to the symmetrical structure of the lower limbs.
[0065] The first row of single temperature sensors 20 is vertically positioned to correspond to the neck and shoulder area, monitoring temperature changes caused by head movements to determine if the blanket is covering the user's neck. The second row of three equidistant temperature sensors 20 is horizontally arranged to cover the chest and abdomen area. When the user turns over, the three temperature signals generate continuous data changes, identifying trunk displacement and determining whether the blanket is below or offset from the user's chest position. The third row of symmetrically arranged temperature sensors 20 uses a mirror distribution to match the left and right movements of the lower limbs. When the legs lift the blanket, the temperature difference between the two sides is simultaneously captured, thus combining with the sensors above to achieve comprehensive monitoring of the overall body temperature distribution. The equal spacing between adjacent rows and the horizontal spacing of the temperature sensors 20 creates a uniform matrix of vertical and horizontal intervals. This maintains independent monitoring of the neck, shoulder, chest, abdomen, and lower limb areas while ensuring spatial continuity of temperature data both horizontally and vertically, avoiding blind spots. When the blanket slips and causes a temperature drop in a certain area, the corresponding temperature sensor 20 immediately captures this change and transmits the data in real time through the output interface 30, promptly reminding the user to adjust the blanket coverage.
[0066] Compared to existing technologies, current temperature monitoring devices typically employ randomly distributed or unidirectionally arranged temperature sensors 20, which cannot form a spatial mapping with the physiological characteristics of a person lying down, resulting in fragmented temperature signal acquisition. This embodiment, through a combination of a vertical three-row layout and a horizontal equidistant symmetrical arrangement, creates a biomimetic distribution structure for the temperature sensor network 20. The temperature signal acquisition range completely covers the core heat source area of the human body, and the data distribution exhibits spatial correlation.
[0067] Through the above technical solution, this application can establish a precise correspondence between the temperature sensor 20 and body parts based on the human lying posture, and improve the correlation between temperature signals and limb movements through zoned monitoring. When the blanket is kicked off, the lower limb symmetrical temperature sensor 20 can capture a sudden drop in temperature on one side, the chest equidistant temperature sensor 20 can identify abnormal temperature distribution caused by torso rolling, and the neck and shoulder single-point temperature sensor 20 can determine head displacement, thereby comprehensively judging the occurrence of the blanket-kicking action.
[0068] Optionally, the temperature sensor 20 in the first row corresponds to the neck and shoulder area, the three temperature sensors 20 in the second row correspond to the chest area of the human body, and the two sensors in the third row correspond to the left and right lower limb areas, respectively.
[0069] The neck and shoulder region refers to the physiological area from the neck to the shoulders, which can be identified using thermal imaging experiments to determine the temperature-sensitive areas in this region. The chest region refers to the mid-thigh area from the sternum to the ribs on both sides, which can be identified anatomically to determine the core temperature zones of the heart and lungs. The left and right lower limb regions refer to the symmetrical areas of the legs from the hip joints to the knee joints, which can be identified using surface temperature distribution testing to determine the main heat dissipation areas of the legs.
[0070] The placement of the temperature sensors 20 is spatially matched to the human physiological structure. The first row of temperature sensors 20 covers the neck and shoulder area, which, due to its dense blood vessel distribution and large exposed area, can quickly reflect temperature fluctuations in the upper body. The second row of three temperature sensors 20 is arranged at equal intervals to cover the chest area, forming a triangular monitoring network for the core body temperature of the torso, eliminating measurement errors from a single temperature sensor 20. The third row of two temperature sensors 20 is symmetrically distributed in the left and right lower limb areas, enabling independent bilateral detection to identify sudden drops in temperature on one side of the limb. The correspondence between the layout of the temperature sensors 20 and the key temperature zones of the human body is established using a biothermodynamic model, and a grid positioning method is used in the sewing process to fix the positions of the temperature sensors 20.
[0071] Compared with the prior art, the traditional solution using randomly distributed temperature sensors 20 fails to establish an association with the human anatomical structure, resulting in the lack of physiological significance in temperature signal acquisition. In this embodiment, through the precise correspondence between the temperature sensors 20 and specific body parts, the temperature change data can reflect the real physiological state, overcoming the problem of monitoring failure caused by the deviation of the temperature sensors 20 from the target area in the traditional layout.
[0072] Through the above technical solution, the present application realizes targeted temperature monitoring of different physiological regions of the human body, solving the problem of temperature signal distortion caused by the unreasonable layout of the temperature sensors 20 in the prior art. Through the zonal monitoring of the neck and shoulders, chest, and lower limbs, it is possible to accurately capture temperature abnormalities in each part, providing differential data support for judging the kicking-off quilt action and avoiding the defect of insufficient sensitivity of the whole-body average temperature measurement to local temperature changes.
[0073] Optionally, a plurality of wire grooves 40 are provided in the quilt core 10, where:
[0074] The plurality of wire grooves 40 are used for wiring and connecting adjacent temperature sensors 20. The wire grooves 40 extend along the arrangement direction of the temperature sensors 20 to form a "ji" - shaped wiring channel. A wire connection node is provided at the intersection of each wire groove 40, and the connection node coincides with the installation position of the corresponding temperature sensor 20.
[0075] The wire groove 40 refers to a groove structure embedded inside the quilt core 10, which can be realized by molding with a flexible silicone material, providing a directional guiding channel for the connection lines between the temperature sensors 20. The "ji" - shaped wiring channel refers to a shape similar to the stroke of a Chinese character composed of a continuous curved path, which can be realized by a serpentine broken - line trajectory design, using the迂回走向 to disperse the pulling effect of external forces on the line. The wire connection node refers to a reinforcement structure at the intersection of the wire grooves 40, which can be realized by an injection - molded plastic buckle for fixing the connection ends of multi - directional lines and maintaining contact stability.
[0076] Among them, the line is constrained within the continuous bending path of the "ji" - shaped wire groove 40 during laying, and the connection line between adjacent temperature sensors 20 extends along a preset channel. When the line needs to turn, it is transitioned through the connection node at the intersection, and the buckle structure of the node mechanically fixes the ends of the lines with different directions. Since the setting position of the connection node coincides with the installation coordinates of the temperature sensor 20, the line connection point and the temperature sensor 20 body are in the same vertical projection area, facilitating synchronous maintenance during maintenance.
[0077] Compared with existing technologies, the wiring of the temperature sensor 20 inside a traditional quilt uses a free-running method, which makes the wiring prone to tangling or breakage due to external pulling, and the connection points lack fixed support. This embodiment constrains the wiring route within a predetermined path through a structured wiring channel, uses a T-shaped bending structure to absorb external stress, and at the same time makes the connection nodes and the temperature sensor 20 form a spatial position matching relationship, establishing a wiring system with self-supporting characteristics.
[0078] Through the above-mentioned technical means, this embodiment effectively solves the problem of signal transmission interruption caused by messy lines. The orderly arrangement of lines in a fixed channel avoids mutual entanglement. The reinforced design of the connection nodes ensures the reliability of contact. The position of the temperature sensor 20 coincides with that of the node, reducing the complexity of maintenance operations, thereby improving the overall operational stability of the temperature monitoring system.
[0079] Optionally, refer to Figure 2 Another embodiment of this utility model provides a quilt, based on the above. Figure 1 In the embodiment shown, the quilt core 10 is provided with a plurality of wiring grooves 40, wherein:
[0080] The plurality of wiring channels 40 include a plurality of horizontal branches and vertical branches, wherein the horizontal branches are interconnected with adjacent vertical branches to form a "convex" shaped structure.
[0081] The horizontal branches refer to the wiring channels extending horizontally along the core 10, which can be implemented using a channel structure with a width of 3 mm to 5 mm, used to guide the temperature sensor 20 wiring along the horizontal direction. The vertical branches refer to the wiring channels extending vertically along the core 10, which can be implemented using a channel structure of the same width as the horizontal branches, used to constrain the vertical direction of the wiring. Pairwise cross-linking refers to the horizontal and vertical branches forming a cross connection at a predetermined position, which can be achieved through a slotted through-hole design at the intersection of the channels, fixing the wiring at the intersection point and preventing displacement. The "convex" shaped structure refers to the wiring network formed by a specific cross-linking method of the horizontal and vertical branches, which can be achieved by setting a main vertical branch in the central area and extending horizontal branches to both sides, used to constrain wiring in different directions within a fixed path.
[0082] Among them, the cross-link design of the horizontal branch and the vertical branch divides the wiring path of the temperature sensor 20 into multiple independent regions, and the lines in each region are orderly connected through the cross-link points. For example, in the "convex" shaped structure, the central vertical branch serves as the main channel passing through the core 10, and the two lateral branches are cross-linked with it to form branches extending outward, and each branch corresponds to the installation position of a different temperature sensor 20. After the line extends from the main channel to the lateral branch, it is connected to the temperature sensor 20 along a fixed path, avoiding the cross-over and overlap of different lines in the wiring groove 40. The through design of the cross-link point enables the line to maintain a straight path when turning, so as to reduce the signal loss caused by bending.
[0083] Compared with the prior art, the wiring of the traditional core 10 usually adopts a straight channel or a cross-shaped mesh channel, and the lines are prone to entanglement in the cross-over area, resulting in signal interference or the risk of wire breakage. However, the "convex" shaped structure restricts the line path within a specific area through a branch layout with distinct primary and secondary branches, and the through connection method of the cross-link points avoids the bending and extrusion of the lines when turning, thus significantly reducing the probability of line entanglement. [[ID=The control device 50 refers to an electronic module used to receive and process signals from the temperature sensor 20. This can be implemented using a circuit board integrating a main control chip (such as an MCU) and a wireless communication module. Its function is to convert the temperature signal into a transmittable data format. The detachable electrical connection refers to the physical connection and separation between devices via a plug-in interface. This can be achieved using a matching structure of Type-C, Micro, or Lightning male and female connectors. Its function is to allow independent maintenance or replacement of the control device 50 without affecting the structure of the quilt core 10. The wired or wireless transmission method refers to the selective configuration of the signal transmission path. Wireless transmission can be achieved using Bluetooth or Wi-Fi modules, or wired transmission can be achieved via a USB data cable. Its function is to adapt to signal transmission needs in different environments.
[0088] In this system, after the temperature sensor 20 detects temperature signals from various parts of the body, the signals are transmitted to the output interface 30 through the internal wiring of the quilt core 10. The control device 50 is connected to the output interface 30 via a detachable interface, converts the temperature signals into digital signals, and then sends them to the user terminal via wired or wireless means depending on environmental conditions. The user terminal analyzes the temperature data to determine whether the user has kicked off the quilt; for example, it triggers an alarm when the temperature of a certain part of the body remains below a threshold. Since it does not rely on visual monitoring equipment, the signal transmission process is entirely based on changes in temperature parameters to determine the behavior.
[0089] Compared to existing technologies, current blanket-kicking detection solutions rely on cameras to capture images of users' body movements, requiring camera installation in the bedroom. This presents risks of limited infrared imaging accuracy at night and privacy breaches. This embodiment eliminates the need for camera deployment by linking temperature signals with the user terminal. It directly judges user behavior through changes in physiological parameters, maintaining monitoring sensitivity even in dark environments, while avoiding the collection of facial or body image data.
[0090] Through the aforementioned technical means, this embodiment solves the privacy protection deficiencies caused by image monitoring, achieving non-visual recognition of blanket-kicking behavior. The temperature signal transmission method is unaffected by ambient light conditions, ensuring the accuracy of nighttime monitoring. The user terminal can receive real-time warning information without needing to access the monitored person's sleeping space.
[0091] Optionally, refer to Figure 5 Another embodiment of this utility model provides a quilt, based on the above... Figure 3 and Figure 4 In the embodiment shown, the control device 50 includes a control chip 51 and a wireless chip 52, wherein:
[0092] The control chip 51 is electrically connected to the plurality of temperature sensors 20; the wireless chip 52 is electrically connected to the control chip 51 and is communicatively connected to the user terminal, and is used to transmit the temperature signal to the user terminal.
[0093] The control chip 51 is the core processing unit used to receive and process temperature signals. It can be implemented using a microcontroller such as the STM32 series. It establishes a data interaction channel with the temperature sensor 20 through the SPI bus and undertakes the functions of synchronous acquisition and preprocessing of multiple signals. The wireless chip 52 is the transmission module that realizes short-range wireless communication. It can be implemented using an integrated Wi-Fi / Bluetooth dual-mode chip such as the ESP32. It interacts with the control chip 51 through the UART interface and supports the TCP / IP protocol stack to achieve network connection with smart terminals.
[0094] In this system, temperature sensors 20 collect temperature signals from various parts of the human body in real time and transmit them to a control chip 51 via a wired connection. The control chip 51 uses pre-programmed data to perform analog-to-digital conversion and data packetization on the multiple signals. This processing employs a traditional data processing program to form a standardized data frame structure. The processed temperature data is then transmitted to a wireless chip 52 via a serial communication interface. The wireless chip 52 converts the data into radio frequency signals according to a pre-programmed communication protocol and establishes a wireless link with the smart terminal via the 2.4GHz frequency band. This transmission method avoids the complex wiring structure of traditional monitoring systems and eliminates the potential threat to user privacy posed by optical devices such as cameras.
[0095] Compared to existing technologies, traditional blanket-kicking monitoring solutions often employ fixed video surveillance or pressure sensing devices, which suffer from low image recognition accuracy at night, complex wiring, and the risk of damaging the bedding structure. This embodiment utilizes a wireless temperature signal transmission mechanism, completely eliminating the need for wiring while ensuring real-time data transmission. Its radio frequency signal-based transmission method maintains stable communication quality even in low-light environments and avoids the privacy risks associated with optical surveillance.
[0096] Through the aforementioned technical means, this embodiment achieves real-time wireless transmission of bedside temperature data, effectively resolving the conflict between the complex wiring and privacy protection of traditional monitoring equipment. The digital processing of temperature signals and standardized transmission protocols enable data adaptation to various smart terminal devices, while the low-power characteristics of the wireless communication module ensure continuous operation for extended periods, providing reliable technical support for monitoring nighttime blanket-kicking behavior.
[0097] Optionally, refer to Figure 6 In another embodiment of this utility model, a quilt is provided, based on the above. Figure 5In the illustrated embodiment, the control device 50 further includes a signal power interface 53, wherein:
[0098] The first signal terminal of the signal power interface 53 is connected to the input terminal of the control chip 51, the second signal terminal of the signal power interface 53 is detachably connected to the output interface 30, and the power terminal of the signal power interface 53 is used to connect to an external power source.
[0099] The signal power interface 53 is a composite interface integrating signal transmission and power supply functions. It can be implemented using a multi-contact connector and has independent signal transmission and power supply channels internally. The first signal terminal is the input terminal for receiving signals from the temperature sensor 20. Specifically, it can be directly connected to the input port of the control chip 51 using metal contacts or pins to achieve the shortest path signal transmission. The second signal terminal is the signal transmission terminal for establishing a detachable connection with the output interface 30. Specifically, it can be implemented using a pluggable connector to facilitate quick separation of the control device 50 and the quilt core 10 module. The power supply terminal is the interface for connecting to an external power source. It can be implemented using a USB interface or a DC power interface, allowing power supply via an external adapter or power bank. The second signal terminal and the power supply terminal can be combined into one interface and configured as a Type-C interface according to the output interface 30 standard, enabling the external power source and control device 50 to perform both power supply and signal transmission functions through a single interface. The power supply terminal of the signal power interface 53 can also integrate a power management module, which can be implemented using an LTC4056 charging management chip. It has overvoltage protection and current limiting functions to ensure the power supply stability of the control device 50 when connected to power supplies of different specifications.
[0100] The control chip 51 receives temperature signals from the temperature sensor 20 via a first signal terminal, ensuring the shortest possible signal transmission path. The second signal terminal and output interface 30 are pluggable, allowing the control device 50 to be physically separated from the comforter 10 for easy individual maintenance or replacement. The power supply terminal, when connected to an external power source, can provide continuous power to the control device 50 or power the built-in battery.
[0101] The signal transmission and power supply channels are arranged separately within the interface, forming a physically isolated structure to avoid electromagnetic interference affecting signal quality. The detachable design of the interface allows the control device 50 to operate independently or be quickly assembled with the comforter core 10, adapting to the needs of different usage scenarios.
[0102] Compared to existing technologies, current solutions typically employ fixed wiring or single-function interfaces, leading to susceptibility to signal interference, limited power supply options, and difficult equipment maintenance. For example, the traditional control device 50 connects the temperature sensor 20 via soldered or fixed cables, making detachment difficult. This embodiment integrates signal transmission, power supply, and detachable connection functions into a single interface through an integrated signal and power interface 53, solving the problems of complex wiring, inconvenient maintenance, and limited power supply options in existing technologies. The discrete channel design avoids mutual interference between signals and power, while the pluggable structure enhances the modularity of the equipment.
[0103] Through the aforementioned technical means, this embodiment achieves a stable connection between the control device 50, the temperature sensor 20, and the external power supply, ensuring efficient transmission of the temperature signal and flexibility in power supply. Physical isolation between the signal transmission channel and the power supply channel effectively reduces the risk of electromagnetic interference. The detachable interface design simplifies equipment maintenance, and the external power supply connection extends the device's lifespan while avoiding the safety hazards associated with a built-in power supply.
[0104] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
