[0001] The utility model relates to the technical field of Internet of Things control, and in particular to an electronic tag component, a diaper, and an abnormal analysis and early warning system based on the diaper. Background Art

[0002] As we all know, diapers are disposable care products that are mainly used to absorb and lock urine to keep the wearer's skin dry and hygienic. They are of great use value for infants and special groups. However, existing diapers do not have an active reminder function for abnormalities (for example, there is a situation where urine has been absorbed and locked and needs to be changed, but it has not been changed for a long time), which leads to many problems on the user's body caused by untimely replacement of diapers, such as bedsores, eczema and even rot on the skin, which seriously affects the user's health.

[0003] At present, in order to solve this problem, the inertial R&D thinking of many corporate research teams and professional research institutions is to continuously update the technology in the physical direction of diapers, such as urine adsorption structure, urine locking structure, material breathability and structure, so as to improve the many health problems caused by untimely diaper replacement. However, this kind of continuous technical update in the physical direction can only improve related usage problems, but cannot avoid the continued occurrence of related usage problems.

[0004] Therefore, how to break the inertial R&D thinking of continuing to follow the physical direction of diapers themselves, and seek a R&D path and technical solution that is safe to use, easy to operate, and cost-controlled beyond the physical direction of diapers themselves has become a technical problem that needs to be solved urgently.

[0010] The transition antenna segment is provided with an electric small loop antenna, the electric small loop antenna is provided with a second tag chip, the second substrate segment is located on the upper side of the first half-wave dipole antenna, and the second substrate segment is parallel to the first half-wave dipole antenna along the length direction.

[0011] Preferably, the first half-wave dipole antenna, the second half-wave dipole antenna and the transition antenna segment are in the same straight line in the length direction.

[0012] Preferably, the first base segment and the first half-wave dipole antenna are in the same straight line in the length direction.

Therefore, the phrases such as "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments" that appear in the differences in the present application do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. In addition, the terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0034] The following is an exemplary description of the hardware environment and software environment of the device involved in the embodiments of the present application.

[0035] The following combination Figure 1 An exemplary principle description of the signal interaction of the diaper-based abnormal analysis and early warning system is given.

[0036] See also Figure 1 , which is a schematic diagram of signal interaction of a diaper-based abnormal analysis and early warning system provided by an embodiment of the utility model.

[0037] In one embodiment of the utility model, the diaper-based abnormal analysis and early warning system includes a monitoring device 1, a diaper 2 that supports a radio frequency signal communication connection with the monitoring device 1, and a portable electronic device 3 that supports a wireless signal (e.g., Bluetooth signal, Wi-Fi signal and / or wireless communication signal (e.g., 2G, 3G, 4G, 5G)) communication connection with the monitoring device 1. In this embodiment, an electronic tag component 6 is configured on the diaper 2, and the monitoring device 1 sends a radio frequency signal. If the diaper 2 is within the magnetic field induction range of the radio frequency signal, the electronic tag component 6 on the diaper 2 will generate an induced current and send a radio frequency signal to the monitoring device 1 based on the generated induced current; the monitoring device 1 receives the radio frequency signal sent by the electronic tag component 6, decodes and analyzes the received radio frequency signal, and determines whether it is necessary to send an abnormal warning message in a preset format to the portable electronic device 3 according to the analysis result (Example 1, the abnormal warning message in a preset format sent may be "There is urine in the diaper worn by the caregiver, and it is recommended to change it in time"; Example 2, if the monitoring device 1 that sends the abnormal warning message is bound to the specific location information (for example, bed No. 03), the abnormal warning message in a preset format sent may be "There is urine in the diaper worn by the person in bed No. 03, and it is recommended to change it in time"). If it is necessary to send the abnormal warning message, the abnormal warning message in a preset format is directly sent to the portable electronic device 3. In this embodiment, the monitoring device 1 and the portable electronic device 3 can be paired via a Wi-Fi device or a Bluetooth module, and the monitoring device 1 directly sends the abnormal warning information to the paired portable electronic device 3.

[0038] In another embodiment of the utility model, the abnormal analysis and early warning system based on diapers includes a monitoring device 1, a diaper 2 that supports radio frequency signal communication connection with the monitoring device 1, a backend server 5 that communicates with the monitoring device 1 through the Internet (for example, traditional Internet or mobile Internet), and a portable electronic device 3 that supports wireless signal communication connection with the backend server 5. In this embodiment, an electronic tag component 6 is configured on the diaper 2, and the monitoring device 1 sends a radio frequency signal. If the diaper 2 is within the magnetic field induction range of the radio frequency signal, the electronic tag component 6 on the diaper 2 will generate an induced current and send a radio frequency signal to the monitoring device 1 based on the generated induced current; the monitoring device 1 receives the radio frequency signal sent by the electronic tag component 6, decodes and analyzes the received radio frequency signal, and determines whether it is necessary to send abnormal early warning information in a preset format according to the analysis result. If it is necessary to send the abnormal early warning information, it sends a warning information sending request to the backend server 5; after receiving the warning information sending request, the backend server 5 responds to the warning information sending request and sends the abnormal early warning information in a preset format to the portable electronic device 3. In this embodiment, the monitoring device 1 and the portable electronic device 3 can be registered and paired in the background server 5. The background server 5 responds to the warning information sending request and sends the abnormal warning information to the portable electronic device 3 registered and paired with the monitoring device 1.

[0039] It should be noted that in actual use scenarios, the monitoring device 1 can be placed at a specific position on the mattress (for example, see Figure 6 The monitoring device can also be placed at any other suitable location near the mattress, as long as the monitoring device 1 can communicate with the radio frequency electronic tag on the diaper placed at any location on the mattress normally. No further details will be given here.

[0040] The following combination Figure 2-4 The structure of the electronic tag assembly 6 mounted on the diaper 2 will be described as an example.

[0041] See also Figure 2 As shown, an embodiment of the utility model provides a device that can be installed on Figure 1 A schematic structural diagram of the electronic tag assembly 6 on the diaper 2 is shown.

[0042] The electronic tag assembly 6 includes a first radio frequency electronic tag for detecting a first radio frequency signal indicating that the diaper 2 is in a perceptible area, and a second radio frequency electronic tag for detecting a second radio frequency signal indicating the presence of liquid (e.g., urine). The first radio frequency electronic tag is a liquid-insensitive electronic tag, and the second radio frequency electronic tag is a liquid-sensitive electronic tag.

[0043] It should be noted that: a liquid-sensitive electronic tag refers to an electronic tag whose emitted RF signal strength value attenuates linearly with respect to the liquid humidity value in a humid working environment. The larger the humidity value, the smaller the emitted RF signal strength value. When the humidity value of the working environment tends to 100%, the emitted RF signal strength value tends to 0; a liquid-insensitive electronic tag refers to an electronic tag whose emitted RF signal strength value does not attenuate or weakly attenuates with respect to the liquid humidity value in a humid working environment. For example, for an ultra-high frequency (e.g., 860-960MHZ) RF electronic tag based on a sewn antenna, when the humidity value of the working environment changes in the range of [0%, 100%], the emitted RF signal strength value changes by less than a preset value (e.g., 5dB).

[0044] In this embodiment, the first radio frequency electronic tag is a radio frequency electronic tag based on a slot antenna (see Figure 3 As shown), the second radio frequency electronic tag is a radio frequency electronic tag based on an electric small loop antenna and a half-wave dipole antenna (see Figure 4The first radio frequency electronic tag includes a first conductive substrate, which includes a first substrate segment L1, a second substrate segment L2, and a transitional substrate segment L0 electrically connecting the first substrate segment L1 and the second substrate segment L2; the first substrate segment L1 is provided with a straight slot 60 and a first tag chip 61 arranged on one side of the slot 60; the first substrate segment L1 and the second substrate segment L2 are horizontally misaligned in the length direction, and the second substrate segment L2 is located on the upper side of the first substrate segment L1 in the width direction (the first substrate segment L1, the transitional substrate segment L0, the second substrate segment L2, the slot 60, and the first tag chip 61 constitute a radio frequency signal slot antenna of a special shape). The second radio frequency electronic tag includes a first half-wave dipole antenna K1, a second half-wave dipole antenna K2, and a transition antenna segment K0 electrically connected to the first half-wave dipole antenna K1 and the second half-wave dipole antenna K2, the transition antenna segment K0 is provided with an electric small loop antenna 63, the electric small loop antenna 63 is provided with a second tag chip 62, the first half-wave dipole antenna K1, the second half-wave dipole antenna K2 and the transition antenna segment K0 are in the same straight line in the length direction; the second substrate segment L2 is located on the upper side of the first half-wave dipole antenna K1, the second substrate segment L2 is parallel to the first half-wave dipole antenna K1 along the length direction, and the first substrate segment L1 and the first half-wave dipole antenna K1 are in the same straight line in the length direction. The advantages of the above shape and structure are: reducing the difficulty of batch manufacturing, improving manufacturing efficiency, effectively improving the physical resistance of the electronic tag component 6 to wrinkles, ensuring that the single tag has a sufficient antenna area range to ensure antenna efficiency, while effectively reducing the longitudinal area range of the diaper 2 occupied by the electronic tag component 6, ensuring concentrated signal detection at key locations (the electronic tag component 6 is usually set at the geometric center position of the water-absorbing layer corresponding to the diaper 2), reducing the shielding effect of the human body on the radio frequency signal under different usage postures of the diaper 2, and in addition, it can also reduce the use of substrate consumables by the electronic tag.

[0045] Preferably, the horizontal misalignment distance between the second substrate segment L2 and the first substrate segment L1 in the length direction is greater than the maximum width of the first half-wave dipole antenna K1 in the width direction (while ensuring that sufficient space is left on the lower side of the second substrate segment L2 to accommodate the first half-wave dipole antenna K1, mutual interference of signals can be reduced), and is less than 2 times the maximum width of the first substrate segment L1 in the width direction, or less than 2 times the maximum width of the first half-wave dipole antenna in the width direction, or less than 2 times the larger width value between the maximum width of the first substrate segment L1 in the width direction and the maximum width of the first half-wave dipole antenna in the width direction (which can ensure that the spacing distance between the second substrate segment L1 and the first half-wave dipole antenna K1 in the width direction is moderate, further improve the physical resistance of the tag assembly to wrinkles, further reduce the difficulty of batch manufacturing, and further reduce the usage of substrate consumables of the electronic tag).

[0046] In this embodiment, the above-mentioned shape and structure of the electronic tag component 6 bring about the following technical effects: it can ensure that the second base segment L2 is parallel to the first half-wave dipole antenna K1 in the length direction, it can ensure that there is enough space on the lower side of the second base segment L2 to accommodate the first half-wave dipole antenna K1, it can ensure that the second base segment L1 and the first half-wave dipole antenna K1 are in the same straight line in the length direction, effectively reducing the signal interference between the first radio frequency electronic tag and the second radio frequency electronic tag; while resisting signal interference, it can ensure that the spacing distance between the second base segment L1 and the first half-wave dipole antenna K1 in the width direction is moderate, reducing the difficulty of batch manufacturing, improving manufacturing efficiency, effectively reducing the length space and width space occupied by the electronic tag component 6 in the diaper 2, improving the physical resistance of the electronic tag component 6 to wrinkles, and forming an effective balance between the signal anti-interference ability and the physical resistance to wrinkles, so that the electronic tag component 6 is suitable for the diaper 2 based on multi-type radio frequency signals The liquid abnormality analysis and early warning application scenario of the diaper 2.

[0047] The further explanation of “the first base segment L1 and the second base segment L2 are horizontally misaligned in the length direction” is: a minimum rectangular bounding box X1 (for example, Figure 3 The dotted rectangular frame X1 shown in the figure is used to make a minimum rectangular enclosing frame X2 (for example, Figure 3 The dotted rectangular frame X2 shown in the figure, the midline of the minimum rectangular enclosing frame X1 along the length direction is parallel to the midline of the minimum rectangular enclosing frame X2 along the length direction but are not on the same straight line. In this case, it is said that "the first base segment L1 and the second base segment L2 are horizontally misaligned in the length direction".

[0048] The “displacement distance of the second base segment L2 and the first base segment L1 in the length direction” is further explained as: the lower side frame edge of the minimum rectangular enclosing frame X1 (for example, Figure 3 The lower frame edge E1 of the dotted rectangular frame X1 shown in FIG. 1 and the lower frame edge E2 of the minimum rectangular bounding frame X2 (for example, Figure 3 The vertical distance in the width direction of the lower frame edge E2 of the dotted rectangular frame X2 shown in FIG. Figure 3 The vertical distance d0 in the width direction between the extended line of the lower frame edge E1 in the length direction and the extended line of the lower frame edge E2 in the length direction is the vertical distance).

[0049] The further explanation of “the first half-wave dipole antenna K1, the second half-wave dipole antenna K2 and the transition antenna segment K0 are in the same straight line in the length direction” is: a minimum rectangular enclosing frame Y1 (for example, Figure 4 The dotted rectangular frame Y1 shown in the figure is used to make a minimum rectangular enclosing frame Y2 (for example, Figure 4 The dotted rectangular frame Y2 shown in the figure is used to make a minimum rectangular enclosing frame Y0 (for example, Figure 4 In the dotted rectangular box Y0 shown in the figure, the midline of the minimum rectangular enclosing box Y0 along the length direction, the midline of the minimum rectangular enclosing box Y1 along the length direction and the midline of the minimum rectangular enclosing box Y2 along the length direction are all on the same straight line. In this case, it is said that "the first half-wave dipole antenna K1, the second half-wave dipole antenna K2 and the transition antenna segment K0 are all on the same straight line in the length direction".

[0050] The “second base segment L2 is parallel to the first half-wave dipole antenna K1 along the length direction, and the first base segment L1 and the first half-wave dipole antenna K1 are in the same straight line in the length direction” is further explained as: the midline of the minimum rectangular enclosing frame X2 along the length direction is parallel to the midline of the minimum rectangular enclosing frame Y1 along the length direction, and the midline of the minimum rectangular enclosing frame X1 along the length direction is in the same straight line as the midline of the minimum rectangular enclosing frame Y1 along the length direction. In this case, it is said that “the second base segment L2 is parallel to the first half-wave dipole antenna K1 along the length direction, and the first base segment L1 and the first half-wave dipole antenna K1 are in the same straight line in the length direction”.

[0051] The “maximum width of the first half-wave dipole antenna K1 or the first substrate segment L1 in the width direction” is further explained as: a minimum rectangular enclosing frame (for example, Figure 4 The dashed rectangular box Y1 or Figure 3As shown in the dashed rectangular frame X1), the width of the minimum rectangular enclosing frame is the "maximum width in the width direction" of the corresponding part.

[0052] A further explanation of “the larger width value between the maximum width of the first base segment L1 in the width direction and the maximum width of the first half-wave dipole antenna in the width direction” is: if the maximum width of the first base segment L1 in the width direction is greater than or equal to the maximum width of the first half-wave dipole antenna in the width direction, then the maximum width of the first base segment L1 in the width direction is the larger width value; otherwise, the maximum width of the first half-wave dipole antenna in the width direction is the larger width value.

[0053] It should be noted that any technical features in the mathematical sense involved in all embodiments of the utility model, such as "parallel", "vertical", "on the same straight line", etc., are only for the sake of simplicity of description and do not mean that in the actual manufacturing and use of the product, the actual shape and structure of the corresponding parts of the product must absolutely reach the same level as the described technical features in the mathematical sense. Those skilled in the art should know that due to the constraints of various physical conditions, natural conditions and technical conditions, in the actual industrial application process, there must be reasonable errors between the actual shape and structure of the corresponding parts of the product and the ideal literal features. The existence of these reasonable errors is the inevitable result of complying with the laws of nature. These reasonable errors must be taken into account when interpreting the characteristics of the technical solution disclosed in the utility model.

[0054] It should be noted that the production and manufacturing process of the electronic tag component 6 is the same as the existing production and manufacturing process, and no special production and manufacturing process is required. For example, the production and manufacturing processes that can be used include: chip packaging of the tag chips of the first radio frequency electronic tag and the second radio frequency electronic tag respectively (for example, the chip can be packaged in a plastic module by welding technology to protect the chip from the external environment. The relevant manufacturing process is an existing process and will not be described in detail here); the tag antennas of the first radio frequency electronic tag and the second radio frequency electronic tag are respectively manufactured (for example, it can be completed by printing, that is, printing a conductive material on a plastic substrate, and cutting and / or bending it to form an antenna of a specific shape. The relevant manufacturing process is an existing process and will not be described in detail here); the packaged chips of the first radio frequency electronic tag and the second radio frequency electronic tag and the manufactured tag antenna are respectively bonded together to form a complete first radio frequency electronic tag and a second radio frequency electronic tag (for example, it can be The packaged chip and the tag antenna are fixed together using an adhesive to form an integrated single tag. The related manufacturing process is an existing process and will not be described in detail here); based on the design structure of the electronic tag component 6, the complete first radio frequency electronic tag and the second radio frequency electronic tag are respectively adhered to the common substrate in sequence to form a complete electronic tag component 6 (for example, the complete first radio frequency electronic tag and the second radio frequency electronic tag can be adhered to the common substrate using an adhesive to form an integrated tag. During batch production, the first radio frequency electronic tag and the second radio frequency electronic tag can be used as components and quickly mounted on the complete common substrate. During or after batch mounting, the single electronic tag component 6 can be subjected to tearable structural processing on the complete common substrate. These processes are all existing processes and will not be described in detail here); subsequent processes are performed (for example, testing, coding, and packaging. The related processes are all existing processes and will not be described in detail here).

[0055] The following combination Figure 5 The structure of the diaper 2 will be described as an example.

[0056] See also Figure 5 As shown, Figure 1 The layered structure diagram of the diaper 2 is shown. In one embodiment of the present invention, the diaper 2 includes a surface layer, a guide layer, a water-absorbing layer and a bottom film, and the electronic tag assembly 6 can be fixedly installed on the guide layer and / or the bottom film (the installation position on the guide layer and / or the bottom film can be any suitable position, for example, near the side position, near the geometric center, etc., in order to improve the sensitivity of abnormal urine analysis, it is preferably installed near the geometric center).

[0057] It should be noted that: Figure 5The layered structure of the diaper 2 shown is only one embodiment of the present invention. In other embodiments of the present invention, the diaper 2 may also include any other applicable material layers. When the layered structure of the diaper 2 changes, the installation position of the electronic tag component 6 may also be adaptively adjusted, as long as the electronic tag component 6 is installed on a material layer that can quickly contact a humid environment. In addition, in other embodiments of the present invention, in order to reduce the use cost of diapers, the electronic tag component 6 can be replaced with a single liquid-sensitive electronic tag (for example, it can be replaced with a second radio frequency electronic tag). The application method of the liquid-sensitive electronic tag can refer to the following for Figure 11-13 The example description is not repeated here.

[0058] It should be noted that the production and manufacturing process of the diaper 2 is the same as the existing production and manufacturing process, and no special production and manufacturing process is required. For example, the production and manufacturing processes that can be used include: making an absorbent core (for example, non-woven fabric, hot melt adhesive and water-absorbent resin can be stacked together in a certain proportion, and then subjected to high-temperature hot pressing by a hot press to form an absorbent core. The relevant processes are all existing processes and will not be repeated here); processing the surface layer, the guide layer and the bottom film (the relevant processes are all existing processes. The installation method of the electronic tag component 6 on the guide layer and / or the bottom film can be a common glue bonding method, a Velcro bonding method, or sewing the edge of the base of the electronic tag component 6 to the guide layer and / or the bottom film. It will not be repeated here); assembly and packaging (the relevant processes are all existing processes. For example, the assembly process can be to stack the absorbent core, the guide layer, the surface layer and the bottom film in a determined order, and then cut, seal, punch and other processes through a large production line to form a complete diaper).

[0060] It should be noted that: Figure 7-8 The structure of the components of the monitoring device 1 and the RFID (Radio Frequency Identification) card reader 15 in one embodiment of the present utility model is only exemplified. It can be understood by those skilled in the art that: Figure 7-8 The component structure shown does not constitute a structural limitation on the monitoring device 1 and the RFID card reader 15. In other embodiments of the utility model, the monitoring device 1 and / or the RFID card reader 15 may include fewer or more components than shown in the figure, or fewer or more specific component combinations than shown in the figure, or the arrangement structure of the components of the monitoring device 1 and / or the RFID card reader 15 may be different from the arrangement structure shown in the figure, which will not be elaborated here.

[0061] See also Figure 7 As shown, Figure 1 The internal structure diagram of the monitoring device 1 is shown. In one embodiment of the present utility model, the monitoring device 1 includes a communication unit 11, a memory 13, an RFID card reader 15, and a processor 10 that is respectively connected to the communication unit 11, the memory 13 and the RFID card reader 15. The memory 13 stores a diaper-based abnormal analysis and early warning program 12 that can be called and executed by the processor 10. When the diaper-based abnormal analysis and early warning program 12 is called and executed by the processor 10, the execution Figure 9-13 The steps involved in the monitoring device 1 in the flowchart shown in any of the figures are as follows: Figure 9-13 The accompanying drawings are described in detail herein.
