Description

Technical Field

[0001] This application relates to the field of smart home technology, specifically to a temperature control method based on a sofa and related products. Background Technology

[0002] In daily life, some indoor spaces (such as bedrooms) have sofas (such as long sofas) placed at the foot of the bed. Sofas placed at the foot of the bed can not only enhance the aesthetics of the interior design, but also support the blankets that slip off the bed and prevent them from sliding to the floor at the foot of the bed.

[0003] In practice, it has been found that when the indoor temperature is low (such as when the indoor air conditioner is low), the part of the blanket that slips off the bed onto the sofa loses its body temperature and its immediate temperature drops rapidly. When this part of the blanket is lifted up and used to cover the user's body (such as the feet), the user usually feels uncomfortable due to the large temperature difference between the immediate temperature of this part of the blanket and the user's body temperature, thus affecting the user's sleep quality. Summary of the Invention

[0004] This application discloses a sofa-based temperature control method and related products, which are used to reduce the discomfort caused by temperature differences when the part of the quilt that has slipped onto the sofa is lifted up and re-covered on the bed user's body, so as to avoid affecting the sleep quality of the bed user.

[0005] The first aspect of this application discloses a temperature control method based on a sofa, wherein the sofa is placed at the foot of a smart bed, and the method includes:

[0006] The sofa detects whether part of the blanket on the smart bed has slipped onto the sofa; if so, it detects whether there is still a user on the smart bed; if so, it obtains the real-time body temperature value of the user on the bed.

[0007] The sofa control system keeps the current temperature value of the sofa consistent with the instantaneous human body temperature value, so that the instantaneous temperature value of the contact surface of the part of the quilt that is in contact with the sofa is consistent with the instantaneous human body temperature value.

[0008] As an optional implementation, in the first aspect of this application embodiment, the portion of the quilt is part of a whole quilt on the smart bed, and the whole quilt is evenly divided into several sub-parts, each sub-part having a built-in flexible RFID tag, and each flexible RFID tag storing a preset information segment; the sofa detects whether the portion of the quilt on the smart bed has slipped onto the sofa, including:

[0009] The sofa detects whether it reads the preset information segment stored in the flexible RFID tag built into any of the sub-parts of the entire quilt; if it reads it, it detects that part of the quilt on the smart bed has slipped onto the sofa; if it does not read it, it detects that part of the quilt on the smart bed has not slipped onto the sofa.

[0010] As another optional implementation, in the first aspect of the embodiments of this application, each of the flexible RFID tags stores a preset information segment containing an identifier ID of the smart bed's hotspot and a key, and any two flexible RFID tags store the same key in their preset information segments, and the key is a valid access key for the smart bed's hotspot. Then, after the sofa detects that part of the blanket on the smart bed has slipped onto the sofa, the method further includes:

[0011] The sofa establishes a wireless communication connection between the sofa and the hotspot of the smart bed based on the hotspot identifier ID of the smart bed and the key.

[0012] The sofa detects whether there is still a user on the smart bed, including:

[0013] The sofa sends a user detection instruction message to the smart bed via the wireless communication connection. The user detection instruction message is used to instruct the smart bed to detect whether there is still a user on the smart bed.

[0014] The sofa receives the user detection results sent by the smart bed via the wireless communication connection, and identifies whether there is still a user on the smart bed based on the user detection results;

[0015] In response to the user detection command message, the smart bed detects whether there is a human-shaped force area on the smart bed; if a human-shaped force area exists, a user detection result is generated indicating that there is a user on the smart bed; if no human-shaped force area exists, a user detection result is generated indicating that there is no user on the smart bed.

[0016] As another optional implementation, in the first aspect of the embodiments of this application, after the sofa controls the current temperature value of the sofa to be consistent with the instantaneous human body temperature value, so that the instantaneous temperature value of the contact surface of the part of the quilt in contact with the sofa is consistent with the instantaneous human body temperature value, the method further includes:

[0017] The sofa detects the target weight value of a portion of the quilt;

[0018] The sofa sends first interactive information to the smart bed via the wireless communication connection, and the first interactive information includes at least the target weight value.

[0019] Upon receiving the first interaction information, the smart bed determines whether the target weight value contained in the first interaction information is greater than or equal to a preset weight value; if so, it detects whether the current indoor temperature is lower than or equal to a preset temperature; if so, it detects whether the torso of the user on the bed is completely covered by the remaining blanket except for the portion of the blanket; if not, it assumes the user on the bed is at risk of getting cold; and performs a first vibration operation on the user on the bed, the first vibration operation being used to alert the user to the risk of getting cold; and determines a first temperature increment value based on the target weight value, wherein the first temperature increment value is proportional to the target weight value; and calculates the sum of the first temperature increment value and the instantaneous human body temperature value as a first target temperature; and controls the temperature of the smart bed to rise to the first target temperature to reduce the risk of the user on the bed getting cold.

[0020] As another optional implementation, in the first aspect of the embodiments of this application, each of the flexible RFID tags stores a preset information segment that further includes location information, and the location information contained in the preset information segments of any two flexible RFID tags is different. The location information contained in the preset information segment of each flexible RFID tag is the location information of a certain sub-part of the built-in flexible RFID tag on the whole quilt; after the sofa controls the current temperature value of the sofa to be consistent with the instantaneous human body temperature value, so that the instantaneous temperature value of the contact surface of the part of the quilt in contact with the sofa is consistent with the instantaneous human body temperature value, the method further includes:

[0021] The sofa sends second interactive information to the smart bed via the wireless communication connection. The second interactive information includes location information contained in a preset information segment stored in the flexible RFID tags embedded in each sub-part of the partial quilt. The sub-part of the partial quilt is a part of the several sub-parts into which the whole quilt is evenly divided.

[0022] Upon receiving the second interactive information, the smart bed identifies each sub-part of the quilt based on the location information contained in the preset information segment stored in the flexible RFID tags embedded in each sub-part of the quilt; it then removes each sub-part from the several sub-parts evenly divided into the entire quilt to obtain the currently remaining sub-parts on the smart bed; and it calculates whether the number of currently remaining sub-parts on the smart bed is equal to or less than a preset number; if so, it detects whether the current indoor temperature is... If the temperature is lower than or equal to a preset temperature, then the user on the bed is at risk of getting cold; and a second vibration operation is performed on the user on the bed to alert them of the risk of getting cold; a second temperature increment is determined based on the number of currently remaining sub-parts, wherein the second temperature increment is inversely proportional to the number of currently remaining sub-parts; the sum of the second temperature increment and the instantaneous human body temperature is calculated as a second target temperature; and the temperature of the smart bed is controlled to rise to the second target temperature to reduce the risk of the user on the bed getting cold.

[0026] The acquisition unit is used to acquire the real-time body temperature value of the user on the smart bed when the second detection unit detects that there is still a user on the bed.

[0027] The control unit is used to control the current temperature value of the sofa to be consistent with the instantaneous human body temperature value, so that the instantaneous temperature value of the contact surface of the part of the blanket that is in contact with the sofa is consistent with the instantaneous human body temperature value.

[0028] As an optional implementation, in the second aspect of this application, the portion of the quilt is part of the whole quilt on the smart bed, and the whole quilt is evenly divided into several sub-parts. Each sub-part has a built-in flexible RFID tag, and each flexible RFID tag stores a preset information segment. The first detection unit is specifically used to detect whether the preset information segment stored in the flexible RFID tag built into any sub-part of the whole quilt is read. If it is read, it is detected that the portion of the quilt on the smart bed has slipped onto the sofa. If it is not read, it is detected that the portion of the quilt on the smart bed has not slipped onto the sofa.

[0029] As another optional implementation, in the second aspect of the embodiments of this application, each of the flexible RFID tags stores a preset information segment containing an identifier ID of the smart bed's hotspot and a key, and any two flexible RFID tags store the same key in their preset information segments, and the key is the legitimate access key for the smart bed's hotspot. The sofa further includes:

[0030] The establishment unit is used to establish a wireless communication connection between the sofa and the hotspot of the smart bed based on the hotspot identifier ID of the smart bed and the key after the first detection unit detects that part of the quilt on the smart bed has slipped onto the sofa.

[0031] The second detection unit detects whether there is still a user on the smart bed in the following way:

[0032] The system sends a user detection instruction message to the smart bed via the wireless communication connection. The user detection instruction message is used to instruct the smart bed to detect whether there is still a user on the smart bed. The system also receives the user detection result sent by the smart bed via the wireless communication connection and identifies whether there is still a user on the smart bed based on the user detection result.

[0033] In response to the user detection command message, the smart bed detects whether there is a human-shaped force area on the smart bed; if a human-shaped force area exists, a user detection result is generated indicating that there is a user on the smart bed; if no human-shaped force area exists, a user detection result is generated indicating that there is no user on the smart bed.

[0034] As another optional implementation, in a second aspect of the embodiments of this application, the sofa further includes:

[0036] A first transmitting unit is configured to transmit first interactive information to the smart bed via the wireless communication connection, wherein the first interactive information includes at least the target weight value.

[0037] Upon receiving the first interaction information, the smart bed determines whether the target weight value contained in the first interaction information is greater than or equal to a preset weight value; if so, it detects whether the current indoor temperature is lower than or equal to a preset temperature; if so, it detects whether the torso of the user on the bed is completely covered by the remaining blanket except for the portion of the blanket; if not, it assumes the user on the bed is at risk of getting cold; and performs a first vibration operation on the user on the bed, the first vibration operation being used to alert the user to the risk of getting cold; and determines a first temperature increment value based on the target weight value, wherein the first temperature increment value is proportional to the target weight value; and calculates the sum of the first temperature increment value and the instantaneous human body temperature value as a first target temperature; and controls the temperature of the smart bed to rise to the first target temperature to reduce the risk of the user on the bed getting cold.

[0038] As another optional implementation, in the second aspect of the embodiments of this application, each of the flexible RFID tags stores a preset information segment that further includes location information, and the location information contained in the preset information segments of any two flexible RFID tags is different. The location information contained in the preset information segment of each flexible RFID tag is the location information of a certain sub-part of the built-in flexible RFID tag on the entire quilt; the sofa further includes:

[0039] The second transmitting unit is configured to send second interactive information to the smart bed via the wireless communication connection after the control unit controls the current temperature value of the sofa to be consistent with the instantaneous human body temperature value, so that the instantaneous temperature value of the contact surface of the portion of the quilt in contact with the sofa is consistent with the instantaneous human body temperature value. The second interactive information includes location information contained in a preset information segment stored in the flexible RFID tags built into each sub-part of the portion of the quilt; wherein, each sub-part of the portion of the quilt is a part of the plurality of sub-parts into which the whole quilt is evenly divided.

[0040] Upon receiving the second interactive information, the smart bed identifies each sub-part of the quilt based on the location information contained in the preset information segment stored in the flexible RFID tags embedded in each sub-part of the quilt; it then removes each sub-part from the several sub-parts evenly divided into the entire quilt to obtain the currently remaining sub-parts on the smart bed; and it calculates whether the number of currently remaining sub-parts on the smart bed is equal to or less than a preset number; if so, it detects whether the current indoor temperature is... If the temperature is lower than or equal to a preset temperature, then the user on the bed is at risk of getting cold; and a second vibration operation is performed on the user on the bed to alert them of the risk of getting cold; a second temperature increment is determined based on the number of currently remaining sub-parts, wherein the second temperature increment is inversely proportional to the number of currently remaining sub-parts; the sum of the second temperature increment and the instantaneous human body temperature is calculated as a second target temperature; and the temperature of the smart bed is controlled to rise to the second target temperature to reduce the risk of the user on the bed getting cold.

[0041] A third aspect of this application discloses a sofa, which is placed at the foot of a smart bed, comprising:

[0042] Memory containing executable program code;

[0043] A processor coupled to the memory;

[0044] The processor calls the executable program code stored in the memory and performs the following steps:

[0045] Detect whether part of the blanket on the smart bed has slipped onto the sofa; if so, detect whether there is still a user on the smart bed; if so, obtain the real-time body temperature value of the user on the bed.

[0046] The current temperature value of the sofa is controlled to be consistent with the instantaneous human body temperature value, so that the instantaneous temperature value of the contact surface of the part of the blanket that is in contact with the sofa is consistent with the instantaneous human body temperature value.

[0047] As an optional implementation, in the third aspect of this application embodiment, the portion of the quilt is part of a whole quilt on the smart bed, and the whole quilt is evenly divided into several sub-parts, each sub-part having a built-in flexible RFID tag, and each flexible RFID tag storing a preset information segment; the processor detects whether the portion of the quilt on the smart bed has slipped onto the sofa in the following way:

[0048] The system detects whether a preset information segment stored in a flexible RFID tag embedded in any of the sub-parts of the entire quilt is read; if read, it detects that part of the quilt on the smart bed has slipped onto the sofa; if not read, it detects that part of the quilt on the smart bed has not slipped onto the sofa.

[0049] As another optional implementation, in the third aspect of the embodiments of this application, each of the flexible RFID tags stores a preset information segment containing an identifier ID of the smart bed's hotspot and a key, and any two flexible RFID tags store the same key in their preset information segments, and the key is a valid access key for the smart bed's hotspot. Then, after the processor detects that part of the blanket on the smart bed has slipped onto the sofa, it further performs the following steps:

[0050] A wireless communication connection is established between the sofa and the hotspot of the smart bed based on the hotspot identifier ID of the smart bed and the key.

[0051] The processor detects whether there is still a user in the smart bed in the following way:

[0052] The system sends a user detection instruction message to the smart bed via the wireless communication connection. The user detection instruction message is used to instruct the smart bed to detect whether there is still a user on the smart bed. The system also receives the user detection result sent by the smart bed via the wireless communication connection and identifies whether there is still a user on the smart bed based on the user detection result.

[0053] In response to the user detection command message, the smart bed detects whether there is a human-shaped force area on the smart bed; if a human-shaped force area exists, a user detection result is generated indicating that there is a user on the smart bed; if no human-shaped force area exists, a user detection result is generated indicating that there is no user on the smart bed.

[0054] As another optional implementation, in a third aspect of the present application, after the processor controls the current temperature value of the sofa to be consistent with the instantaneous human body temperature value, so that the instantaneous temperature value of the contact surface of the portion of the blanket in contact with the sofa is consistent with the instantaneous human body temperature value, the following steps are further performed:

[0055] Detect the target weight value of the portion of the quilt;

[0056] The first interactive information is sent to the smart bed via the wireless communication connection, and the first interactive information includes at least the target weight value.

[0057] Upon receiving the first interaction information, the smart bed determines whether the target weight value contained in the first interaction information is greater than or equal to a preset weight value; if so, it detects whether the current indoor temperature is lower than or equal to a preset temperature; if so, it detects whether the torso of the user on the bed is completely covered by the remaining blanket except for the portion of the blanket; if not, it assumes the user on the bed is at risk of getting cold; and performs a first vibration operation on the user on the bed, the first vibration operation being used to alert the user to the risk of getting cold; and determines a first temperature increment value based on the target weight value, wherein the first temperature increment value is proportional to the target weight value; and calculates the sum of the first temperature increment value and the instantaneous human body temperature value as a first target temperature; and controls the temperature of the smart bed to rise to the first target temperature to reduce the risk of the user on the bed getting cold.

[0058] As another optional implementation, in the third aspect of the embodiments of this application, each of the flexible RFID tags stores a preset information segment that also includes location information, and the location information contained in the preset information segments of any two flexible RFID tags is different. The location information contained in the preset information segment of each flexible RFID tag is the location information of a certain sub-part of the built-in flexible RFID tag on the whole quilt. After the processor controls the current temperature value of the sofa to be consistent with the instantaneous human body temperature value, so that the instantaneous temperature value of the contact surface of the part of the quilt in contact with the sofa is consistent with the instantaneous human body temperature value, the following steps are also performed:

[0059] The second interactive information is sent to the smart bed via the wireless communication connection. The second interactive information includes location information contained in a preset information segment stored in the flexible RFID tags built into each sub-part of the partial quilt. The sub-part of the partial quilt is a part of the several sub-parts into which the whole quilt is evenly divided.

[0060] Upon receiving the second interactive information, the smart bed identifies each sub-part of the quilt based on the location information contained in the preset information segment stored in the flexible RFID tags embedded in each sub-part of the quilt; it then removes each sub-part from the several sub-parts evenly divided into the entire quilt to obtain the currently remaining sub-parts on the smart bed; and it calculates whether the number of currently remaining sub-parts on the smart bed is equal to or less than a preset number; if so, it detects whether the current indoor temperature is... The temperature is set to be lower than or equal to a preset temperature; if so, the user on the bed is assumed to be at risk of getting cold; a second vibration operation is performed on the user on the bed to alert them to the risk of getting cold; a second temperature increment is determined based on the number of currently remaining sub-parts, wherein the second temperature increment is inversely proportional to the number of currently remaining sub-parts; the sum of the second temperature increment and the instantaneous human body temperature is calculated as a second target temperature; and the temperature of the smart bed is controlled to rise to the first target temperature to reduce the risk of the user on the bed getting cold.

[0061] The fourth aspect of this application discloses a storage medium storing a computer program thereon, which, when executed by a processor, implements the steps of the sofa-based temperature control method in the first aspect of this application or any optional implementation of the first aspect of this application.

[0062] Compared with the prior art, the embodiments of this application have the following beneficial effects:

[0063] In this embodiment, when the sofa placed at the foot of the smart bed detects that part of the blanket on the smart bed has slipped onto the sofa, and also detects that there is still a user on the smart bed, the current temperature value of the sofa can be controlled to be consistent with the real-time body temperature value of the user on the bed. This ensures that the real-time temperature value of the contact surface of the part of the blanket that is in contact with the sofa is also consistent with the real-time body temperature value. This can reduce the discomfort caused by the temperature difference when the blanket is lifted and re-covered to cover the user on the bed, and avoid affecting the sleep quality of the user on the bed.

[0064] Furthermore, implementing the embodiments of this application can enable bed users to enjoy a warm and comfortable experience, thereby helping to maintain or improve sleep comfort and overall quality.

[0065] Furthermore, implementing the embodiments of this application can enhance the intelligence level of sofas, which is conducive to the widespread application of sofas. Attached Figure Description

[0069] Figure 3 This is a flowchart illustrating the third embodiment of the sofa-based temperature control method disclosed in this application.

[0070] Figures 4-8 These are schematic diagrams of the first to fifth embodiments of the sofa disclosed in this application. Detailed Implementation

[0071] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0072] It should be noted that the terms "comprising" and "having" and any variations thereof in the embodiments of this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to these processes, methods, products, or devices.

[0073] This application discloses a sofa-based temperature control method and related products, which can reduce the discomfort caused by temperature differences when the part of the blanket that has slipped onto the sofa is lifted and re-covered on the bed, thus avoiding affecting the sleep quality of the bed user. A detailed description is provided below with reference to the accompanying drawings.

[0074] Please see Figure 1 , Figure 1 This is a flowchart illustrating the first embodiment of the sofa-based temperature control method disclosed in this application. The sofa is placed at the foot of a smart bed. Figure 1 As shown, this sofa-based temperature control method includes the following steps:

[0075] 101. The sofa detects whether part of the blanket on the smart bed has slipped onto the sofa; if not, the process ends; if so, proceed to step 102.

[0076] In some alternative implementations, the indoor environment (e.g., a room) where the sofa and smart bed are located can be equipped with cameras, and the sofa can maintain a communication connection with the cameras (e.g., via Wi-Fi or Bluetooth). Based on this, the camera can detect in real time whether part of the blanket from the smart bed has slipped onto the sofa; if so, it sends a notification message to the sofa indicating that part of the blanket from the smart bed has slipped onto the sofa, thus enabling the sofa to detect that part of the blanket from the smart bed has slipped onto the sofa.

[0077] In some alternative embodiments, the entire quilt on the smart bed (this portion of the quilt is part of the whole quilt) is evenly divided into several sub-parts, and each sub-part has a built-in flexible radio frequency identification (RFID) tag, and each flexible RFID tag stores a preset information segment. The preset information segment can be a preset character or a preset string, which is not limited in this embodiment. Accordingly, in step 101 above, the sofa can detect whether a portion of the quilt on the smart bed has slipped onto the sofa in the following way:

[0078] The sofa detects whether it reads the preset information segment stored in the flexible RFID tag built into any of the several sub-sections that are evenly divided into the whole quilt; if it reads the information, the sofa can detect that part of the quilt on the smart bed has slipped onto the sofa; if it does not read the information, the sofa can detect that part of the quilt on the smart bed has not slipped onto the sofa.

[0079] In this embodiment, the sofa can have a built-in RFID reader. When any one of the several sub-sections of the evenly divided quilt slides onto the sofa, the built-in RFID reader can read the preset information segment stored in the flexible RFID tag embedded in that sub-section, thus the sofa can detect that part of the quilt from the smart bed has fallen onto the sofa. Conversely, when none of the several sub-sections of the evenly divided quilt has fallen onto the sofa, the built-in RFID reader will not be able to read the preset information segment stored in the flexible RFID tag embedded in any sub-section, and the sofa can detect that part of the quilt from the smart bed has not fallen onto the sofa. Implementing this method not only eliminates the need to install cameras in the indoor environment (such as a room) where the sofa and smart bed are located, but also improves the intelligence level of the sofa, which is conducive to the widespread application of sofas.

[0080] 102. The sofa detects whether there is still a user on the smart bed; if not, the process ends; if so, steps 103 and 104 are executed.

[0081] In some optional implementations, the sofa and smart bed can maintain a communication connection (such as Wi-Fi or Bluetooth). When the sofa detects that part of the blanket on the smart bed has slipped onto it, it can instruct the smart bed to detect whether a user is still on the smart bed. Accordingly, the smart bed can use sensors (such as pressure sensors) to detect whether there is a human-shaped pressure area on the smart bed; if a human-shaped pressure area exists, it generates a user detection result indicating that a user is on the smart bed; if no human-shaped pressure area exists, it generates a user detection result indicating that no user is on the smart bed; and sends the generated user detection result to the sofa. The sofa can then identify whether a user is still on the smart bed based on the user detection result; if not, the process ends; if so, steps 103 and 104 are executed.

[0082] 103. The sofa obtains the real-time body temperature value of the user on the bed.

[0083] In some optional implementations, when the sofa detects that a user is still on the smart bed, it can instruct the smart bed to detect the user's real-time body temperature. Correspondingly, the smart bed can respond to the sofa's instruction, using a temperature detection device to detect the user's real-time body temperature and send this value to the sofa, allowing the sofa to obtain the user's real-time body temperature. This temperature detection device includes at least one temperature sensing probe, which may include, but is not limited to, patch probes, cochlear probes, and axillary probes. Furthermore, the temperature sensing probe can be made of a consumable material (i.e., disposable) or a sterilizable and reusable material. In use, the temperature sensing probe can be attached to the user's skin or placed on the surface of the smart bed facing the user (such as the mattress surface).

[0084] In some application scenarios, a smart bed can be a single-user bed (i.e., a single bed), and the corresponding body temperature sensing probe can be placed on the surface of the smart bed facing the user (such as the mattress surface of the smart bed). The real-time body temperature value of the single user lying on the smart bed detected by the body temperature sensing probe is used as the real-time body temperature value of the user on the smart bed.

[0085] In other application scenarios, a smart bed can be a multi-user bed (i.e., a bed with multiple users). The corresponding body temperature sensing probe can be attached to the body surface of one of the multiple users (such as an infant, child, elderly person, or woman) on the smart bed. The real-time body temperature value of that user detected by the body temperature sensing probe is used as the real-time body temperature value of the user on the smart bed.

[0086] 104. The sofa controls the current temperature value of the sofa to be consistent with the instantaneous human body temperature value, so that the instantaneous temperature value of the contact surface of the part of the quilt that is in contact with the sofa is consistent with the instantaneous human body temperature value.

[0087] It is understood that, in this embodiment of the application, the current temperature value of the sofa is the current temperature value of the contact layer of the sofa.

[0088] In some alternative embodiments, a heating layer may be provided beneath the contact layer of the sofa, and a heating device for changing the current temperature value of the sofa's contact layer may be fixedly installed inside the heating layer. Accordingly, after obtaining the instantaneous body temperature value of the user on the bed, the sofa can control the heating device fixed inside the heating layer to heat the current temperature value of the sofa's contact layer to the instantaneous body temperature value, thereby making the current temperature value of the sofa's contact layer consistent with the instantaneous body temperature value, so that the instantaneous temperature value of the contact surface of the blanket in contact with the sofa is consistent with the instantaneous body temperature value.

[0089] exist Figure 1 In the described method, when a sofa placed at the foot of the smart bed detects that part of the blanket from the smart bed has slipped onto the sofa, and also detects that there is still a user in the smart bed, the sofa's current temperature value can be controlled to be consistent with the user's instantaneous body temperature. This ensures that the instantaneous temperature value of the contact surface of the blanket that is in contact with the sofa is also consistent with the instantaneous body temperature value. This reduces the discomfort caused by temperature differences when the blanket is lifted and re-covered to the user's body, thus avoiding affecting the user's sleep quality.

[0090] In addition, implementation Figure 1 The described method allows bed users to enjoy a warm and comfortable experience, thereby helping to maintain or improve sleep comfort and overall quality.

[0091] In addition, implementation Figure 1 The described method can also improve the intelligence level of sofas, which is conducive to the widespread application of sofas.

[0092] Please see Figure 2 , Figure 2This is a flowchart illustrating the second embodiment of the sofa-based temperature control method disclosed in this application. The sofa is placed at the foot of a smart bed, and the smart bed provides a full quilt for the user. Further, the quilt is evenly divided into several sub-sections, each sub-section containing a flexible RFID tag, and each flexible RFID tag storing a preset information segment. The preset information segment stored in each flexible RFID tag includes a hotspot identifier ID (the hotspot identifier ID serves as the unique identifier of the hotspot) and a key. Any two flexible RFID tags storing the same key in their preset information segments are identical, and this key is the legitimate access key for the smart bed's hotspot. Figure 2 As shown, this sofa-based temperature control method includes the following steps:

[0093] 201. The sofa detects whether it reads the hotspot ID of the smart bed and a key contained in the preset information segment stored in the flexible RFID tag built into any part of the whole quilt; if it reads it, it detects that part of the quilt on the smart bed has slid onto the sofa, and executes steps 202 to 204.

[0094] In some implementations, if the sofa fails to read the smart bed's hotspot identifier ID and a key contained in the preset information segment stored in the flexible RFID tag embedded in any part of the entire quilt, the sofa can detect that part of the quilt on the smart bed has not slipped onto the sofa, and end the process.

[0095] The preset information segment includes the hotspot identifier ID of the smart bed and a key, which can be formed into a preset string. This application embodiment does not limit this.

[0096] 202. The sofa establishes a wireless communication connection between the sofa and the smart bed's hotspot based on the hotspot identifier ID and the key.

[0097] In this embodiment, the sofa can broadcast a hotspot access request message containing the identifier ID of the smart bed's hotspot and the key. When the smart bed hears the hotspot access request message and recognizes that the identifier ID of the smart bed's hotspot is contained in the hotspot access request message, the smart bed can verify whether the key contained in the hotspot access request message is consistent with the legitimate access key of the smart bed's hotspot. If they are consistent, the sofa is allowed to access the smart bed's hotspot, thereby realizing the wireless communication connection between the sofa and the smart bed.

[0098] In particular, by implementing steps 201 to 202 above, when the sofa detects that part of the blanket on the smart bed has slipped onto the sofa, it can flexibly and quickly establish a wireless communication connection between the sofa and the smart bed's hotspot.

[0099] 203. The sofa sends a user detection instruction message to the smart bed via the wireless communication connection. The user detection instruction message is used to instruct the smart bed to detect whether there is still a user on the smart bed.

[0100] In this system, the smart bed responds to user detection command messages by using sensors (such as pressure sensors) to detect whether there is a human-shaped force area on the smart bed. If a human-shaped force area is found, a user detection result is generated indicating that there is a user on the smart bed. If no human-shaped force area is found, a user detection result is generated indicating that there is no user on the smart bed.

[0101] 204. The sofa receives the user detection result sent by the smart bed via the wireless communication connection, and identifies whether there is still a user on the smart bed based on the user detection result; if not, the process ends; if so, steps 205 and 206 are executed.

[0102] 205. The sofa obtains the real-time body temperature value of the user on the bed.

[0103] The implementation of step 205 can be referred to step 103 above, and will not be repeated in this embodiment.

[0104] 206. The sofa controls the current temperature value of the sofa to be consistent with the instantaneous human body temperature value, so that the instantaneous temperature value of the contact surface of the part of the quilt that is in contact with the sofa is consistent with the instantaneous human body temperature value.

[0105] In some implementations, in Figure 2 In the sofa-based temperature control method shown, after performing step 206, the sofa can also perform the following steps:

[0106] The sofa measures the target weight of this portion of the quilt;

[0107] Furthermore, the sofa sends first interactive information to the smart bed via the wireless communication connection, the first interactive information including at least the target weight value.

[0108] Upon receiving the first interaction information, the smart bed determines whether the target weight value contained in the first interaction information is greater than or equal to a preset weight value. If so, it indicates that too much of the blanket has slipped from the smart bed onto the sofa. Furthermore, the smart bed can detect whether the current indoor temperature is lower than or equal to a preset temperature. If so, it detects whether the user's torso is completely covered by the remaining blanket excluding the affected portion. If not, it assumes the user is at risk of getting cold. A first vibration operation is then performed on the user to alert them of this risk. A first temperature increment value is determined based on the target weight value, and this first temperature increment value is proportional to the target weight value. The sum of the first temperature increment value and the instantaneous body temperature is calculated as the first target temperature. Finally, the temperature of the smart bed is controlled to rise to the first target temperature to reduce the risk of the user getting cold.

[0109] The first temperature increment is proportional to the target weight value; that is, the larger the target weight value, the larger the first temperature increment; and the smaller the target weight value, the smaller the first temperature increment.

[0110] The first target temperature is within the human body's tolerance and will not have any adverse effects on health.

[0111] In some alternative implementations, the sofa may have a built-in weight-measuring element, which includes at least one gravity sensor, allowing the sofa to detect the target weight of that portion of the blanket.

[0112] In some alternative implementations, the sofa can be placed on a weighing platform (such as an electronic induction weighing device), and the sofa maintains a communication connection with the weighing platform. The weighing platform can detect the total weight of the sofa and the portion of the quilt, subtract the known weight of the sofa from the total weight to obtain the target weight of the portion of the quilt, and send the target weight of the portion of the quilt to the sofa, so that the sofa can detect the target weight of the portion of the quilt.

[0113] Understandably, the torso refers to the part of the human body excluding the head and limbs. Generally, the abdomen, which is part of the torso, is more susceptible to cold.

[0114] In this embodiment of the application, the smart bed can use a temperature sensor to measure the current indoor temperature (i.e., the current indoor temperature of the room where the sofa and the smart bed are located).

[0115] In this embodiment, the smart bed may have a built-in vibration massager, with a hemispherical massage head on its top. Based on this, when the smart bed determines that the target weight value is greater than or equal to a preset weight value (indicating that too much of the blanket has slipped from the smart bed onto the sofa), and also detects that the current room temperature is lower than or equal to a preset temperature, and that the user's torso is not completely covered by the remaining blanket excluding that portion, the smart bed assumes the user is at risk of getting cold and controls the massage head of the vibration massager to perform a first vibration operation on the user to alert them of this risk. Accordingly, prompted by the first vibration operation, the user can lift the portion of the blanket that has slipped onto the sofa and re-cover their body, thereby reducing the risk of catching a cold.

[0116] It is evident that implementation Figure 2 The described sofa-based temperature control method can not only reduce the discomfort caused by temperature differences when the part of the blanket that has slipped onto the sofa is lifted and re-covered on the bed user's body, thus avoiding affecting the sleep quality of the bed user, but also reduce the risk of the bed user catching a cold.

[0117] In addition, implementation Figure 2 The described method allows bed users to enjoy a warm and comfortable experience, thereby helping to maintain or improve sleep comfort and overall quality.

[0118] In addition, implementation Figure 2 The described method can also improve the intelligence level of sofas, which is conducive to the widespread application of sofas.

[0119] Please see Figure 3 , Figure 3This is a flowchart illustrating the third embodiment of the sofa-based temperature control method disclosed in this application. The sofa is placed at the foot of a smart bed, and the smart bed provides a full quilt for the user. Further, the quilt is evenly divided into several sub-sections, each sub-section containing a flexible RFID tag, and each flexible RFID tag storing a preset information segment. The preset information segment stored in each flexible RFID tag includes a hotspot identifier ID of the smart bed and a key, and any two flexible RFID tags storing preset information segments contain the same key, which is the legitimate access key for the smart bed's hotspot. Further, each flexible RFID tag storing preset information segment also includes location information, and any two flexible RFID tags storing preset information segments contain different location information; the location information contained in each flexible RFID tag's preset information segment is the location information of a specific sub-section containing the flexible RFID tag on the entire quilt. For example, the first flexible RFID tag stores a preset information segment containing location information "1", which indicates that the sub-part of the first flexible RFID tag embedded in the quilt is located at position 1; the second flexible RFID tag stores a preset information segment containing location information "2", which indicates that the sub-part of the second flexible RFID tag embedded in the quilt is located at position 2; ...; and so on. Figure 4 As shown, this sofa-based temperature control method includes the following steps:

[0120] Steps 301 to 306 are the same as steps 201 to 206 in the previous embodiments, and will not be repeated here.

[0121] 307. The sofa sends second interactive information to the smart bed via the wireless communication connection. The second interactive information includes location information contained in a preset information segment stored in the flexible RFID tags embedded in each sub-part of the quilt. The sub-part of the quilt is part of a plurality of sub-parts into which the whole quilt is evenly divided.

[0122] 308. After receiving the second interactive information, the smart bed identifies each sub-part of the quilt based on the location information contained in the preset information segment stored in the flexible RFID tags built into each sub-part of the quilt.

[0123] It is understandable that the location information contained in the preset information segment stored in any flexible RFID tag can serve as an identifier for a certain sub-part of the quilt. Accordingly, after receiving the second interactive information, the smart bed can identify each sub-part of the quilt based on the location information contained in the preset information segment stored in the flexible RFID tags embedded in each sub-part of the quilt.

[0124] 309. The smart bed removes each sub-part contained in the quilt from the several sub-parts that are evenly divided into the whole quilt, and obtains the current remaining sub-parts of the several sub-parts on the smart bed.

[0125] 310. The smart bed calculates whether the number of the aforementioned sub-parts remaining on the smart bed is equal to or less than a preset number; if so, it detects whether the current indoor temperature is lower than or equal to a preset temperature; if so, it assumes that the user on the bed is at risk of getting cold; and performs a second vibration operation on the user on the bed, the second vibration operation being used to alert the user on the bed that there is a risk of getting cold.

[0126] If the smart bed calculates that the number of the aforementioned sub-parts remaining on the smart bed is equal to or less than a preset number, it indicates that the portion of the quilt that has slid off the smart bed and onto the sofa contains too many sub-parts, which means that the portion of the quilt that has slid off the smart bed and onto the sofa is too large. Consequently, the remaining portion of the entire quilt on the smart bed, excluding this portion of the quilt, is too small.

[0127] 311. The smart bed determines a second temperature increment value based on the number of currently remaining sub-parts; wherein the second temperature increment value is inversely proportional to the number of currently remaining sub-parts; and calculates the sum of the second temperature increment value and the instantaneous human body temperature value as a second target temperature; and controls the temperature of the smart bed to rise to the second target temperature to reduce the risk of the user on the bed catching a cold.

[0128] The second temperature increment is inversely proportional to the number of the currently remaining sub-parts; that is, the smaller the number of the currently remaining sub-parts, the larger the second temperature increment; and the larger the number of the currently remaining sub-parts, the smaller the second temperature increment.

[0129] The second target temperature is within the human body's tolerance and will not have any adverse effects on health.

[0130] It is evident that implementation Figure 3 The described method can not only reduce the discomfort caused by temperature differences when the part of the blanket that has slipped onto the sofa is lifted and re-covered on the bed user's body, thus avoiding affecting the bed user's sleep quality, but also reduce the risk of the bed user catching a cold.

[0131] In addition, implementation Figure 3 The described method allows bed users to enjoy a warm and comfortable experience, thereby helping to maintain or improve sleep comfort and overall quality.

[0132] In addition, implementation Figure 3 The described method can also improve the intelligence level of sofas, which is conducive to the widespread application of sofas.

[0133] Please see Figure 4 , Figure 4 This is a structural schematic diagram of the first embodiment of the sofa disclosed in this application. Wherein, Figure 4 The sofa shown is placed at the foot of a smart bed. Figure 4 As shown, the sofa includes:

[0134] The first detection unit 401 is used to detect whether part of the quilt on the smart bed has slipped onto the sofa;

[0135] The second detection unit 402 is used to detect whether there is still a user on the smart bed when the first detection unit 401 detects that part of the quilt on the smart bed has slipped onto the sofa.

[0136] The acquisition unit 403 is used to acquire the real-time body temperature value of the user on the smart bed when the second detection unit 402 detects that there is still a user on the smart bed.

[0137] Control unit 404 is used to control the current temperature value of the sofa to be consistent with the instantaneous human body temperature value, so that the instantaneous temperature value of the contact surface of the part of the blanket that is in contact with the sofa is consistent with the instantaneous human body temperature value.

[0138] In some optional implementations, the indoor environment (e.g., a room) where the sofa and the smart bed are located can be equipped with cameras, and the sofa can maintain a communication connection with the cameras (e.g., Wi-Fi or Bluetooth). Based on this, the camera can detect in real time whether part of the blanket from the smart bed has slipped onto the sofa; if so, it sends a notification message to the sofa indicating that part of the blanket from the smart bed has slipped onto the sofa, thereby enabling the first detection unit 401 to detect that part of the blanket from the smart bed has slipped onto the sofa.

[0139] In some alternative embodiments, the entire quilt on the smart bed (this portion of the quilt is part of the whole quilt) is evenly divided into several sub-sections, and each sub-section has a built-in flexible RFID tag, and each flexible RFID tag stores a preset information segment. Accordingly, the first detection unit 401 can be used to detect whether the preset information segment stored in the flexible RFID tag built into any sub-section of the entire quilt is read; if it is read, it is detected that part of the quilt on the smart bed has slipped onto the sofa; if it is not read, it is detected that part of the quilt on the smart bed has not slipped onto the sofa.

[0140] In some optional implementations, the sofa and smart bed can maintain a communication connection (such as Wi-Fi or Bluetooth). When the first detection unit 401 detects that part of the blanket on the smart bed has slipped onto the sofa, the corresponding second detection unit 402 can instruct the smart bed to detect whether there is still a user on the smart bed. Accordingly, the smart bed can use sensors (such as pressure sensors) to detect whether there is a human-shaped pressure area on the smart bed; if a human-shaped pressure area exists, a user detection result is generated indicating that there is a user on the smart bed; if no human-shaped pressure area exists, a user detection result is generated indicating that there is no user on the smart bed; and the generated user detection result is sent to the sofa. Accordingly, the second detection unit 402 can identify whether there is still a user on the smart bed based on the user detection result.

[0141] In some optional implementations, when the second detection unit 402 detects that there is still a user on the smart bed, the acquisition unit 403 can instruct the smart bed to detect the real-time body temperature of the user on the bed; accordingly, the smart bed can respond to the sofa's instruction, use a body temperature detection device (such as a body temperature sensing probe) to detect the real-time body temperature of the user on the bed, and send the real-time body temperature of the user on the bed to the sofa, so that the acquisition unit 403 can obtain the real-time body temperature of the user on the bed.

[0142] It is evident that implementation Figure 4 The sofa shown can reduce the discomfort caused by temperature differences when the blanket is lifted to cover the user's body again, thus avoiding affecting the user's sleep quality.

[0143] In addition, implementation Figure 4 The sofa shown can provide a warm and comfortable experience for users in bed, thereby helping to maintain or improve sleep comfort and overall quality.

[0144] In addition, implementation Figure 4 The sofa shown can also enhance its intelligence, which will help to popularize and apply sofas.

[0145] Please see Figure 5 , Figure 5 This is a schematic diagram of the second embodiment of the sofa disclosed in this application. The sofa is placed at the foot of a smart bed, which provides a complete quilt for the user. Further, the quilt is evenly divided into several sub-sections, each sub-section containing a flexible RFID tag, and each flexible RFID tag storing a preset information segment. The preset information segment stored in each flexible RFID tag includes an identifier ID of the smart bed's hotspot and a key. Any two flexible RFID tags storing preset information segments contain the same key, and this key is the legitimate access key for the smart bed's hotspot. Figure 4 Compared to the sofa shown, Figure 5 The sofa shown also includes:

[0146] Establishment unit 405 is used to establish a wireless communication connection between the sofa and the hotspot of the smart bed based on the hotspot identifier ID of the smart bed and the key after the first detection unit 401 detects that part of the quilt on the smart bed has slipped onto the sofa.

[0147] Correspondingly, the second detection unit 402 can detect whether there is still a user on the smart bed in the following ways:

[0148] The system sends a user detection instruction message to the smart bed via the wireless communication connection. The user detection instruction message is used to instruct the smart bed to detect whether there is still a user on the smart bed. The system also receives the user detection result sent by the smart bed via the wireless communication connection and identifies whether there is still a user on the smart bed based on the user detection result.

[0149] The smart bed can respond to user detection command messages to detect whether there is a human-shaped force area on the smart bed; if a human-shaped force area exists, a user detection result is generated to indicate that there is a user on the smart bed; if no human-shaped force area exists, a user detection result is generated to indicate that there is no user on the smart bed.

[0150] in, Figure 5 When the sofa detects that part of the blanket on the smart bed has slipped onto the sofa, it can flexibly and quickly establish a wireless communication connection between the sofa and the smart bed's hotspot.

[0151] Please see Figure 6 , Figure 6 This is a structural schematic diagram of the third embodiment of the sofa disclosed in this application. Figure 5 Compared to the sofa shown, Figure 6 The sofa shown also includes:

[0152] The third detection unit 406 is used to detect the target weight value of the quilt after the control unit 404 controls the current temperature value of the sofa to be consistent with the instantaneous human body temperature value so that the instantaneous temperature value of the contact surface of the part of the quilt in contact with the sofa is consistent with the instantaneous human body temperature value.

[0153] The first transmitting unit 407 is used to transmit first interactive information to the smart bed via the wireless communication connection, the first interactive information including at least the target weight value;

[0154] Upon receiving the first interaction information, the smart bed determines whether the target weight value contained in the first interaction information is greater than or equal to a preset weight value. If so, it indicates that too much of the blanket has slipped from the smart bed onto the sofa. Furthermore, the smart bed can detect whether the current indoor temperature is lower than or equal to a preset temperature. If so, it detects whether the user's torso is completely covered by the remaining blanket excluding the affected portion. If not, it assumes the user is at risk of getting cold. A first vibration operation is then performed on the user to alert them of this risk. A first temperature increment value is determined based on the target weight value, and this first temperature increment value is proportional to the target weight value. The sum of the first temperature increment value and the instantaneous body temperature is calculated as the first target temperature. Finally, the temperature of the smart bed is controlled to rise to the first target temperature to reduce the risk of the user getting cold.

[0155] It is evident that implementation Figure 6 The sofa shown not only reduces the discomfort caused by temperature differences when the part of the blanket that has slipped onto the sofa is lifted to cover the user's body again, thus avoiding affecting the user's sleep quality, but also reduces the risk of the user catching a cold.

[0156] In addition, implementation Figure 6 The sofa shown can provide a warm and comfortable experience for users in bed, thereby helping to maintain or improve sleep comfort and overall quality.

[0157] In addition, implementation Figure 6 The sofa shown can also enhance its intelligence, which will help to popularize and apply sofas.

[0158] Please see Figure 7 , Figure 7This is a structural schematic diagram of the fourth embodiment of the sofa disclosed in this application. The sofa is placed at the foot of a smart bed, which provides a complete quilt for the user. Further, the quilt is evenly divided into several sub-sections, each sub-section containing a flexible RFID tag, and each flexible RFID tag storing a preset information segment. The preset information segment stored in each flexible RFID tag includes the identifier ID of the smart bed's hotspot and a key, and any two flexible RFID tags storing preset information segments contain the same key, which is the legitimate access key for the smart bed's hotspot. Further, each flexible RFID tag storing preset information segment also includes location information, and any two flexible RFID tags storing preset information segments contain different location information; the location information contained in each flexible RFID tag's preset information segment is the location information of a certain sub-section containing the flexible RFID tag on the entire quilt. Figure 5 Compared to the sofa shown, Figure 7 The sofa shown also includes:

[0159] The second transmitting unit 408 is used to send second interactive information to the smart bed via the wireless communication connection after the control unit 404 controls the current temperature value of the sofa to be consistent with the instantaneous human body temperature value, so that the instantaneous temperature value of the contact surface of the part of the quilt that is in contact with the sofa is consistent with the instantaneous human body temperature value. The second interactive information includes the location information contained in the preset information segment stored in the flexible RFID tags built into each sub-part of the quilt; wherein, each sub-part of the quilt is a part of a number of sub-parts that are evenly divided into the whole quilt.

[0160] Upon receiving the second interactive information, the smart bed identifies each sub-part of the quilt based on the location information stored in the preset information segments of the flexible RFID tags embedded in each sub-part of the quilt. It then removes each sub-part from the several sub-parts evenly divided into the entire quilt to obtain the current remaining sub-parts on the smart bed. Next, it calculates whether the current remaining number of sub-parts on the smart bed is equal to or less than a preset number. If so, it detects whether the current room temperature is lower than or equal to a preset temperature. If so, it assumes the user on the bed is at risk of getting cold. Finally, it performs a second vibration operation on the user on the bed to alert them of this risk. Based on the current remaining number of sub-parts, it determines a second temperature increment value, which is inversely proportional to the current remaining number of sub-parts. It calculates the sum of the second temperature increment value and the instantaneous human body temperature as a second target temperature. Finally, it controls the temperature of the smart bed to rise to the second target temperature to reduce the risk of the user on the bed getting cold.

[0161] It is evident that implementation Figure 7 The sofa shown not only reduces the discomfort caused by temperature differences when the part of the blanket that has slipped onto the sofa is lifted to cover the user's body again, thus avoiding affecting the user's sleep quality, but also reduces the risk of the user catching a cold.

[0162] In addition, implementation Figure 7 The sofa shown can provide a warm and comfortable experience for users in bed, thereby helping to maintain or improve sleep comfort and overall quality.

[0163] In addition, implementation Figure 7 The sofa shown can also enhance its intelligence, which will help to popularize and apply sofas.

[0164] Please see Figure 8 , Figure 8 This is a structural schematic diagram of the fifth embodiment of the sofa disclosed in this application. The sofa is placed at the foot of a smart bed. Figure 8 As shown, the sofa includes:

[0165] Memory 801 storing executable program code;

[0166] Processor 802 coupled to memory 801;

[0167] The processor 802 calls the executable program code stored in memory 801 and performs the following steps:

[0168] Detect whether part of the blanket on the smart bed has slipped onto the sofa; if so, detect whether there is still a user on the smart bed; if so, obtain the real-time body temperature of the user on the bed.

[0169] The current temperature of the sofa is controlled to be consistent with the instantaneous human body temperature, so that the instantaneous temperature of the contact surface of the blanket in contact with the sofa is consistent with the instantaneous human body temperature.

[0170] In some optional implementations, the portion of the quilt is part of a whole quilt on the smart bed, and the whole quilt is evenly divided into several sub-parts, each sub-part having a built-in flexible RFID tag, and each flexible RFID tag storing a preset information segment; correspondingly, the processor 802 can detect whether the portion of the quilt on the smart bed has slipped onto the sofa in the following ways:

[0171] The system detects whether a preset information segment stored in a flexible RFID tag embedded in any part of the entire quilt is read; if it is read, it detects that part of the quilt on the smart bed has slipped onto the sofa; if it is not read, it detects that part of the quilt on the smart bed has not slipped onto the sofa.

[0172] In some optional implementations, each flexible RFID tag stores a preset information segment containing the identifier ID of the smart bed's hotspot and a key, and any two flexible RFID tags store the same key in their preset information segments, and this key is the legitimate access key for the smart bed's hotspot. Then, after detecting that part of the blanket on the smart bed has slipped onto the sofa, the processor 802 further performs the following steps:

[0173] Based on the hotspot identifier ID of the smart bed and the key, a wireless communication connection is established between the sofa and the hotspot of the smart bed;

[0174] Accordingly, the processor 802 can detect whether there is still a user in the smart bed in the following ways:

[0175] The system sends a user detection instruction message to the smart bed via the wireless communication connection. The user detection instruction message is used to instruct the smart bed to detect whether there is still a user on the smart bed. The system also receives the user detection result sent by the smart bed via the wireless communication connection and identifies whether there is still a user on the smart bed based on the user detection result.

[0176] In this process, the smart bed responds to a user detection command message by detecting whether there is a human-shaped force area on the smart bed; if a human-shaped force area exists, a user detection result is generated to indicate that there is a user on the smart bed; if no human-shaped force area exists, a user detection result is generated to indicate that there is no user on the smart bed.

[0177] In some optional implementations, the processor 802 controls the current temperature value of the sofa to be consistent with the instantaneous human body temperature value, and after ensuring that the instantaneous temperature value of the contact surface of the portion of the blanket in contact with the sofa is consistent with the instantaneous human body temperature value, the following steps are also performed:

[0178] Detect the target weight value of this part of the quilt;

[0179] The first interactive information is sent to the smart bed via the wireless communication connection, and the first interactive information includes at least the target weight value;

[0180] Upon receiving the first interaction information, the smart bed determines whether the target weight value contained in the first interaction information is greater than or equal to a preset weight value. If so, it indicates that too much of the blanket has slipped from the smart bed onto the sofa. Furthermore, the smart bed can detect whether the current indoor temperature is lower than or equal to a preset temperature. If so, it detects whether the user's torso is completely covered by the remaining blanket excluding the affected portion. If not, it assumes the user is at risk of getting cold. A first vibration operation is then performed on the user to alert them of this risk. A first temperature increment value is determined based on the target weight value, and this first temperature increment value is proportional to the target weight value. The sum of the first temperature increment value and the instantaneous body temperature is calculated as the first target temperature. Finally, the temperature of the smart bed is controlled to rise to the first target temperature to reduce the risk of the user getting cold.

[0181] In some optional implementations, each flexible RFID tag stores a preset information segment that also includes location information, and the location information contained in the preset information segments of any two flexible RFID tags is different. The location information contained in the preset information segment of each flexible RFID tag is the location information of a certain sub-part of the flexible RFID tag embedded in the whole quilt. Correspondingly, after the processor 802 controls the current temperature value of the sofa to be consistent with the instantaneous human body temperature value, so that the instantaneous temperature value of the contact surface of the part of the quilt in contact with the sofa is consistent with the instantaneous human body temperature value, the following steps are also performed:

[0182] The second interactive information is sent to the smart bed via the wireless communication connection. The second interactive information includes the location information contained in the preset information segment stored in the flexible RFID tags built into each sub-part of the quilt. The sub-part of the quilt is a part of a number of sub-parts that are evenly divided into the whole quilt.

[0183] Upon receiving the second interactive information, the smart bed identifies each sub-part of the quilt based on the location information stored in the preset information segments of the flexible RFID tags embedded in each sub-part of the quilt. It then removes each sub-part from the several sub-parts evenly divided into the entire quilt to obtain the current remaining sub-parts on the smart bed. Next, it calculates whether the number of the remaining sub-parts on the smart bed is equal to or less than a preset number. If so, it detects whether the current room temperature is lower than or equal to a preset temperature. If so, it assumes the user on the bed is at risk of getting cold. Finally, it performs a second vibration operation on the user on the bed to alert them of this risk. Based on the number of the currently remaining sub-parts, it determines a second temperature increment value, which is inversely proportional to the number of the currently remaining sub-parts. It calculates the sum of the second temperature increment value and the instantaneous human body temperature as a second target temperature. Finally, it controls the temperature of the smart bed to rise to the second target temperature to reduce the risk of the user on the bed getting cold.

[0184] It is evident that implementation Figure 8 The sofa shown not only reduces the discomfort caused by temperature differences when the part of the blanket that has slipped onto the sofa is lifted to cover the user's body again, thus avoiding affecting the user's sleep quality, but also reduces the risk of the user catching a cold.

[0185] In addition, implementation Figure 8 The sofa shown can provide a warm and comfortable experience for users in bed, thereby helping to maintain or improve sleep comfort and overall quality.

[0186] In addition, implementation Figure 8 The sofa shown can also enhance its intelligence, which will help to popularize and apply sofas.
