Description

Technical Field

[0001] This utility model relates to positioning and location tracking technology, and in particular to an electronic tag and its passive tracking and positioning system. Background Technology

[0002] Active positioning technologies offer high accuracy and speed, typically employing internal devices to actively transmit or receive signals to achieve location, such as GPS and BeiDou positioning. Passive positioning and tracking technologies, on the other hand, are primarily used in the Internet of Things (IoT), particularly in warehousing, logistics, and urban asset management systems. These technologies mainly involve attaching electronic tags to target objects, then using readers to read the tag information to identify the object and combine it with appropriate positioning technologies (such as RFID). While these technologies offer high accuracy, they place stringent requirements on the system or equipment and are currently not suitable for outdoor positioning.

[0003] Active positioning technology requires power and therefore needs charging. The structure of wearable or mobile devices is also relatively complex, making it unsuitable for scenarios requiring prolonged wear without power. However, with the development of IoT technology, especially the widespread adoption of 5G and the construction of various outdoor passive base stations and RFID satellite systems (such as in ocean shipping, polar exploration, and wildlife conservation), passive positioning technology has become a viable option. Furthermore, passive positioning technology manifests as thin and lightweight electronic tags on wearable or mobile devices, requiring no power source and possessing a simple structure, offering advantages that active positioning cannot match.

[0004] However, there is currently no passive positioning technology suitable for outdoor use, which is a technical problem that needs to be solved. At the same time, current electronic tags are mainly made of rigid shells or soft paper-like materials. Rigid ones are inconvenient to carry around, while soft paper ones are not durable. Therefore, this is also a technical problem that needs to be solved. Utility Model Content

[0005] In view of the above-mentioned deficiencies of the prior art, the technical problem to be solved by the present invention is to provide an electronic tag and its passive tracking and positioning system, wherein the electronic tag is easy to carry and durable, and the passive tracking and positioning system can achieve passive positioning and path tracking.

[0006] To achieve the above objectives, this utility model provides an electronic tag, including a base layer, a protective layer, and a functional part. The functional part is disposed or fixed on the base layer, and the portion of the base layer located outside the functional part is fixed and sealed to the protective layer.

[0007] As a further improvement of this utility model, the base layer and the protective layer are made of materials that are resistant to bending and low temperature. The base layer and the protective layer are fixed and sealed by any one or a combination of methods such as hot pressing, adhesive sealing, ultrasonic welding, and adhesive bonding.

[0008] As a further improvement of this utility model, a composite resin mortar coating, a polyurethane coating, an acrylic waterproof coating, or any combination thereof are provided on the outer surface of the base layer and / or protective layer.

[0009] As a further improvement of this utility model, a water-sensitive color-changing material is applied to the surface of the functional part, or / and the inner side of the base layer, protective layer and corresponding functional part, or / and the fixed connection between the base layer and protective layer.

[0010] As a further improvement of this utility model, the functional part consists of an antenna and circuit printed on the base layer or protective layer, and then a chip is installed on the base layer or protective layer.

[0011] As a further improvement of this utility model, the functional part is a complete electronic tag functional part, which is encapsulated in the base layer and protective layer.

[0012] As a further improvement of this utility model, the outer end face of the base layer or protective layer is covered with an adhesive layer formed by a layer of adhesive, and the electronic tag is pasted and fixed in the position required by the user through the adhesive layer; a printed layer is provided, printed or pasted on the end face of the electronic tag away from the adhesive layer.

[0013] As a further improvement of this utility model, the electronic tag is fixed on the inner fixing layer, and the inner fixing layer is installed or fixed to the fixing object; or the outer fixing layer presses the electronic tag onto the fixing object, and the outer fixing edge of the outer fixing layer is installed or fixed to the fixing object.

[0014] As a further improvement of this utility model, a buckle seat is fixed on the wearable or fixed object, and the buckle seat is provided with a spring piece and a buckle piece. The spring piece and the buckle piece are elastic, and a magnetic block is installed on the spring piece. The magnetic block can be attracted to a magnet.

[0015] The buckle piece is equipped with a buckle head, which has an outer bevel and an inner bevel. The inner bevel is attached to the switch bevel of the magnetic block. The inner side of the end of the buckle sleeve has a chamfered bevel, and the inside of the buckle sleeve is a hollow buckle cavity. The buckle cavity is fitted outside the buckle seat, and the buckle sleeve is fixed to the electronic tag.

[0016] As a further improvement of this utility model, a temperature sensor and a humidity sensor are embedded in the electronic tag. There are at least two electronic tags, one of which is attached to the skin or the inside of the clothing, and the other is attached to the outside of the clothing.

[0017] As a further improvement of this invention, a compass is also included, which is detachably mounted on the electronic tag.

[0018] This utility model also discloses a passive tracking and positioning system, including:

[0019] Electronic tags are carried or worn by users. The electronic tags contain the user's ID information, which is then used by the system to associate the user with the user as an identification identifier.

[0020] A reading device is used to read information from electronic tags and upload the read information to a server or a designated device for storage via a network.

[0021] A network is used to connect reading devices, servers, and management terminals.

[0022] The server is used to store information uploaded by reading devices, as well as the storage database and subsequent location and path calculations.

[0023] The reading device reads the ID information of the electronic tag and uploads the location information of the electronic tag to the server via the network. The server records the location information for each location.

[0024] The beneficial effects of this utility model are:

[0025] This invention's electronic tag encapsulates the functional components between a base layer and a protective layer, with the base layer and protective layer sealed and fixed together. This method effectively protects the functional components while also making it convenient to carry. Furthermore, the base layer and protective layer are made of flexible materials that are resistant to bending and low temperatures, which greatly extends the lifespan of the electronic tag. By incorporating an adhesive layer, an inner fixing layer, and an outer fixing layer on the electronic tag, it can be quickly and easily secured for use.

[0026] This invention utilizes electronic tags carried or worn by the user. A reading device reads the electronic tag and obtains its ID information. The time of tag reading, the ID information, and the duration of signal transmission from the tag to the reader are then transmitted to a server via a network. The server uses the ID information to match the corresponding user and calculates the distance or position of the electronic tag relative to the reading device based on the reader's location and the duration of signal transmission, recording this information. Subsequently, routing information is obtained by reading the tag's time and corresponding location information, enabling path tracking. This can be combined with maps, building diagrams, and the reading device's position on these diagrams, along with the user's movement speed, historical location, and paths, to calculate the user's path and location. Furthermore, it can be combined with other positioning devices to achieve more accurate positioning and path calculation to meet different positioning requirements. This invention is particularly suitable for passive positioning monitoring of special populations, such as children, the elderly, and people with mental disabilities.

[0027] Currently, the reading distance of passive electronic tags is not as far as that of active electronic tags. However, the coverage range of a typical 5G-A base station is about 300 meters. Therefore, in cities with a high density of 5G-A base stations, this invention can achieve approximate positioning. Furthermore, in environments such as subways, shopping malls, and supermarkets, where there are numerous 5G-A base stations and reading devices, high-precision indoor positioning can be achieved. The adaptability of this invention in the wild is much lower, as it mainly relies on the reading devices to read and upload information. However, with the rapid development of communication technology and the increasing maturity of IoT technology, this problem will inevitably be solved sooner or later. Of course, in some scenarios, positioning can be achieved by deploying a large number of reading devices outdoors, such as in outdoor personnel location monitoring systems.

[0051] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0052] See Figure 1 , Figure 2 The passive tracking and positioning system of this embodiment includes:

[0053] An electronic tag, carried or worn by the user, contains the user's ID information. The system then associates this ID with the user, serving as an identification marker. In this embodiment, the electronic tag can be encapsulated in a thin film or other portable form that is easy to attach to the user's body or clothing. This allows the user to attach the electronic tag to clothing, pants, shoes, etc., which is significantly thinner and more portable than traditional active positioning methods, causing almost no burden or discomfort to the user. In this embodiment, the electronic tag 100 can be attached to the user's clothing, pants, shoes, or other wearable items through sewing, pasting, or even directly to the user's body.

[0054] A reading device is used to read information from electronic tags and upload the read information to a server or a designated device via a network for storage, so that it can be retrieved and accessed later.

[0055] A network is used to connect reading devices, servers, management terminals, and other devices to a network.

[0056] The server is used to store information uploaded by reading devices, receive instructions and access requests from the management end, store the database, and perform subsequent location and path calculations.

[0057] The management terminal is used to access the server via the network to obtain data from the server or send instructions to the server. In this embodiment, the management terminal can be a PC, a mobile phone, etc. The PC terminal can be a web page or specially designed software, while the mobile terminal is mostly in the form of an app, a mini-program, etc.

[0058] The reading device is a device capable of reading electronic tag information, including electronic tag readers (such as RFID readers), base stations for reading passive tags, and satellite systems for reading passive tags. In this embodiment, many devices are capable of reading electronic tags, such as gates and barriers in shopping malls and supermarkets, subway barriers, 5G-A base stations, RFID base stations, ETC reading devices, vehicle annual inspection electronic tag reading devices, etc. The satellite system is a system in which multiple base stations communicate with satellites, and the satellites then communicate with servers. This type of system is currently used in passive positioning solutions in ocean shipping, polar exploration, and wildlife conservation.

[0059] Since the reading device is fixed, once it reads the RFID tag information, it means the tag is nearby. The distance between the tag and the reading device can be estimated using the signal transmission time between them, indicating the user is within a certain distance range around the reading device. When there are two or more reading devices, triangulation and RFID positioning methods can be used for further tag positioning. The exact location of the tag and the reading device can be calculated using the position of the reading device and the distance between them. All of this can be calculated by software built into the server; the results only need to be output and recorded. When a reading device reads the RFID tag signal, the reading time must also be recorded. If multiple readers read the RFID tag information within a certain time period, the server organizes the information according to the order of reading to obtain path information and achieve path tracking.

[0060] The database can store maps or building structures in advance, and the reading device's position within the stored map or building is fixed. Therefore, once the reading device reads the tag, it can roughly determine the range or location of the electronic tag within the map or building. Simultaneously, the server stores the location and path of each location, forming a historical path or location, to facilitate subsequent location and path calculations.

[0061] During the location and path estimation process, the system first uses maps or building diagrams to determine accessible routes near the reading device. Then, it combines historical paths and location data to estimate the frequency of travel along each route; a higher frequency indicates a greater probability of the user appearing at the next location. Simultaneously, by combining the reading time, the time difference between location estimation and actual movement speed, the approximate location along each path can be further estimated. If a reading device is present at the estimated location but fails to detect the electronic tag's signal, it means the probability of the user traversing that route is low. Through this process, the user's approximate walking path and location can ultimately be determined.

[0062] Of course, it can be combined with other positioning devices to achieve further positioning, such as GPS devices or Beidou devices that are bound to the user ID. By using the positioning information of other positioning devices, the user's movement path and location can be further calculated. This method can achieve high-precision indoor navigation and positioning.

[0063] In some embodiments, the ID of the electronic tag can be associated with the user's public transport account or e-wallet account. This allows a reader to read the tag's ID information and match it with the user's account, enabling authorized payment. This design is similar to current technology that uses a reader to read a phone's NFC data to open Alipay for payment, and could even be used directly. This design greatly simplifies user experience, especially for the elderly, who can easily pay by simply reading the tag. Furthermore, uploading reading information via the reader can assist in user location tracking, particularly for public transport, where the reader's reading route and speed can be used to relatively accurately estimate the user's location. Alternatively, the electronic tag's ID can be associated with access control and attendance devices, allowing these devices to read the tag and upload information.

[0064] See Figure 2 This is a schematic diagram of one type of electronic tag structure, including a base layer 110, a protective layer 120, and a functional part 200 disposed or fixed on the base layer 110. The portion of the base layer 110 located on the outer side of the functional part 200 is fixed and sealed to the protective layer 120, thereby achieving waterproofing and dustproofing. Both the base layer 110 and the protective layer 120 are made of flexible materials.

[0065] The functional part 200 is the functional part of the electronic tag, which generally includes chips, coupling elements, antennas, etc., as long as it can realize the function of the electronic tag.

[0066] In this embodiment, the antenna and circuitry can be printed on the base layer 110 or the protective layer 120 using conductive silver paste, conductive ink, etc., and then mounted on the base layer 110 or the protective layer 120 as a chip. This is essentially the existing printed electronic tag.

[0067] The functional part 200 in this embodiment can also be a separately manufactured component, which is then encapsulated within the base layer 110 and the protective layer 120. This method is preferred in this embodiment because printing is not resistant to bending and has slightly inferior performance. Specifically, the functional part 200 can use a bend-resistant and low-temperature-resistant conductive material for the antenna and circuit, and then the chip can be installed and fixed. In this embodiment, nano-silver wire conductive film or graphene-based conductive film can be selected to fabricate the antenna and circuit of the functional part 200. For example, the antenna and circuit can be punched or cut on the corresponding film, and then the chip and other components can be installed and fixed on the film to obtain the functional part 200, which is then encapsulated within the base layer 110 and the protective layer 120. Nano-silver wire conductive film and graphene-based conductive film have excellent conductivity and mechanical strength, and can maintain stable conductivity even in low-temperature environments (minus 20 degrees Celsius and below), thus meeting the requirements of high-frequency bending and low-temperature use environments. In this case, the functional part 200 can be first bonded and fixed to the base layer 110 or the protective layer 120, and then the base layer 110 and the protective layer 120 can be sealed and fixed.

[0068] The base layer 110 and the protective layer 120 can also be made of materials that are resistant to bending and low temperatures, such as polyimide film and cold-resistant PVC film. At the same time, the base layer 110 and the protective layer 120 can be sealed and fixed by means of heat sealing, adhesive sealing, ultrasonic welding, etc.

[0069] Polyimide films have good adsorption properties, resulting in high printing stability. Therefore, in this embodiment, when the base layer 110 and / or the protective layer 120 are made of polyimide film, circuits or antennas can be printed directly on the base layer 110 and / or the protective layer 120.

[0070] Preferably, if the substrate 110 is made of a material that does not readily adhere to the printed circuit, a layer of polyimide can be uniformly coated on the substrate 110 before printing the circuit. This achieves a better adhesion effect and facilitates the printing of the printed circuit.

[0071] Preferably, to increase the stability and lifespan of the electronic tag, in some embodiments, a composite resin mortar coating, a polyurethane coating, or an acrylic waterproof coating can be sprayed onto the base layer 110 and / or the protective layer 120. These materials have waterproof and wear-resistant properties, thereby effectively improving the overall waterproof and wear-resistant performance of the electronic tag and extending its lifespan.

[0072] Preferably, a water-sensitive color-changing material can be applied to the surface of the functional part 200, or / and the corresponding areas of the base layer 110 and protective layer 120 with the functional part 200, or / and the inner side of the fixed connection between the base layer 110 and protective layer 120. If water enters between the base layer 110 and protective layer 120, the water-sensitive color-changing material will change color, prompting the user to replace it and preventing it from affecting use. The water-sensitive color-changing material can be a water-sensitive pigment, water-sensitive paint, water-sensitive ink, etc.

[0073] Preferably, in some embodiments, the base layer 110 and the protective layer 120 can be fixed together by a connecting layer 610, which can be an adhesive, that is, the base layer 110 and the protective layer 120 are bonded and fixed together by adhesive.

[0074] Preferably, in some embodiments, the base layer 110 and the protective layer 120 can be integrally cast, so that the base layer 110 and the protective layer 120 are naturally integrated and sealed together.

[0075] See Figure 8 In some embodiments, the connecting layer 610 may be omitted, and instead, the base layer 110 and the protective layer 120 may be fixed by welding, hot-melt connection, etc., to form a sealed connection 630.

[0076] See Figure 3 In some embodiments, an adhesive layer 310 may be formed by covering the outer surface of the base layer 110 or the protective layer 120 with an adhesive layer 310, through which the electronic tag 100 is pasted and fixed in the position required by the user. The adhesive may be a self-adhesive label.

[0077] Preferably, a release layer 640 is provided on the end face of the adhesive layer 310 away from the electronic tag 100. The release layer 640 protects the adhesive layer 310 and prevents it from unnecessarily adhering to other items, thus affecting its use. The release layer 640 can be a thin film, specifically referring to the paper or film used to isolate the adhesive portion on the outside of double-sided tape in the prior art. In use, the release layer 640 is peeled off, and the adhesive layer 310 is then pasted to the desired location.

[0078] Preferably, a printed layer 620 can be adhered to the end face of the electronic tag 100 away from the adhesive layer 310. Patterns and text can be printed on the printed layer 620 for decoration or to print the ID information, associated QR codes, etc., of the electronic tag. Alternatively, reflective patterns can be printed, or reflective material can be printed on the entire surface of the printed layer 620 to achieve a reflective function. Of course, the printed layer 620 can also be omitted, and the corresponding patterns, text, reflective materials, etc., can be directly printed or coated onto the electronic tag 100.

[0079] See Figure 4In some embodiments, the electronic tag 100 can be fixed on the inner fixing layer 320, and then the inner fixing layer 320 can be used to fix it on other items, such as clothes, shoes, hats, bags, etc.

[0080] Specifically, an adhesive layer can also be provided on the inner fixing layer 320, so that it can be glued and fixed to other items by the adhesive of the adhesive layer 310.

[0081] Alternatively, the inner fixing layer 320 can be sewn onto the fabric using needle and thread, such as sewing it onto clothes, shoes, hats, bags, etc.

[0082] Or internal fixation layer 320, fixation device 01 (see) Figure 6 The device has hook and loop sides for tear-off fasteners, which are then glued together to secure the item. The item to be fastened can be clothing, shoes, hats, bags, the user's skin, the user's mobile phone, etc.

[0083] Alternatively, the inner fixing layer 320 can be directly fixed to the fixing object 01 with glue. In short, the electronic tag 100 can be fixed to the fixing object 01 through the inner fixing layer 320.

[0084] See Figure 5 In some embodiments, an inner fixing layer hole 310 may be provided on the inner fixing layer 320, and fasteners such as buttons and straps may be provided on the fastener 01. The fasteners such as buttons and straps pass through the inner fixing layer hole 320, and the buttons cannot or are not easy to pass back out of the inner fixing layer hole 321, and the end of the straps passes around the inner fixing layer 320 and is tied tightly, etc., to fix the inner fixing layer 320 to the fastener 01.

[0085] See Figure 6 In some embodiments, an outer fixing layer 330 may be added. The outer fixing layer 330 presses the electronic tag 100 onto the fixing object 01, and the outer fixing edge 331 of the outer fixing layer 330 is fixed to the fixing object 01. The outer fixing edge 331 can be fixed to the fixing object by means of adhesive, adhesive bonding, tear-off fastener bonding, needle and thread sewing, zipper connection, etc. Theoretically, as long as the outer fixing edge 331 is fixed or bonded to the fixing object 01, it is sufficient.

[0086] Preferably, the electronic tag 100 can be pasted or fixed to the outer fixing layer 330 so that the electronic tag 100 and the outer fixing layer 330 become one.

[0087] Preferably, the outer fixing layer 330 may be pasted, fixed, or have a printed layer 620 applied to the end face away from the electronic tag 100.

[0088] See Figure 7In some embodiments, an outer fixing layer hole 332 is provided at the outer fixing edge 331, and a button 340 is provided on the fixing object 01. The large end 341 of the button 340 passes through the outer fixing layer hole 332 to fix the outer fixing edge 331 to the fixing object 01.

[0089] See Figure 8 In some embodiments, the strap 350 passes through the fixing object 01 and the outer fixing layer hole 332, and then the two open ends 351 of the strap 350 are tied together to fix the outer fixing edge 331 to the fixing object 01.

[0090] See Figure 9 In some embodiments, the functional part 200 is manufactured independently and then clamped and fixed between the base layer 110 and the protective layer 120. This method can achieve modular production, and the functional part 200 does not affect the overall manufacturing process during subsequent improvements and upgrades.

[0091] Preferably, in some embodiments, only one of the base layer 110 and the protective layer 120 can be used, and then the functional part 200 can be fixed on it. This can achieve resistance to bending and damage, and facilitate fixing to the fixing object 01.

[0092] See Figure 10 In some embodiments, in Figure 9 Based on the substrate 110 and / or protective layer 120, an adhesive layer 310 is applied. During use, the adhesive layer 310 is used to adhere and fix the device 01 to the fixture. For specific design details, please refer to [reference needed]. Figure 3 .

[0093] See Figure 11 In some embodiments, in Figure 9 Based on the base layer 110 and / or protective layer 120, a fixing layer 320 is set on it, and the fixing layer 320 is used to fix it to the fixing object 01. Specific design details can be found in [reference needed]. Figure 4 .

[0094] See Figure 12 In some embodiments, in Figure 11 Based on this, through holes 101 are provided on the base layer 110 and / or the protective layer 120. Buttons, straps, etc., are fixed to the user's clothing, trousers, shoes, etc. The buttons pass through the buttonholes 101 to fix the electronic tag 100, or the straps pass through the through holes 101 to secure the electronic tag 100 to the fixing object 01. Specific designs can be found in [reference needed]. Figure 8 , Figure 9 .

[0095] See Figure 13In some embodiments, a bag 420 can be provided on the user's clothing, pants, shoes and other wearable items 410. The inside of the bag 420 is a placement cavity 401. The electronic tag 100 is placed in the placement cavity 401, and the opening of the bag 420 is fixed to the wearable item 410. The fixing method can be adhesive, tear-off fastener, sewing or other methods.

[0096] See Figure 14 To prevent the electronic tag 100 from being torn off by human intervention and to ensure easy disassembly and assembly, this embodiment has a buckle seat 430 fixed on the wearable 410. The buckle seat 430 is provided with a spring piece 431 and a buckle piece 451. The spring piece 431 and the buckle piece 451 are elastic. A magnetic block 440 is installed on the spring piece 431. The magnetic block 440 can be attracted to a magnet.

[0097] A latch head 450 is mounted on the latch piece 451. The latch head 450 has an outer bevel 452 and an inner bevel 453. The inner bevel 453 fits against the switch bevel 441 of the magnetic block 440, thereby keeping the latch head 450 inserted into the latch groove 131. The latch groove 131 is located on the latch sleeve 130. The inner side of the end of the latch sleeve 130 has a chamfered bevel 132, and the interior of the latch sleeve 130 is a hollow latch cavity 133. The latch cavity 133 is fitted onto the latch base 430. The latch sleeve 130 is fixed to the electronic tag 100.

[0098] The spring piece 431 applies an elastic force to the magnetic block 440, pushing it inwards towards the inclined surface 453, and the buckle piece 451 applies an elastic force to the buckle head 450, moving it away from the buckle groove 131. Figure 14 The demonstration shows the installed state of the electronic tag. When the electronic tag needs to be removed, a magnet is placed on one side of the wearable 410. The magnet attracts the magnetic block 440 to the wearable 410 through magnetic force. The magnetic block 440 overcomes the elastic force of the spring piece 431 and moves away from the electronic tag 100, thereby causing the switch inclined surface 441 to separate from the inner inclined surface 453. The buckle piece 451 carries the buckle head 450 away from the buckle groove 131 and rotates until it exits into the buckle groove 131. At this time, the electronic tag 100 can be pulled out.

[0099] When installing an electronic tag, the clip sleeve 130 is fitted over the clip head 450 and then pressed against the wearer 410. This causes the chamfered surface 132 to press against the outer chamfered surface 452, applying pressure to the magnetic block 440 against the spring. The magnetic block 440 moves downward so that the clip sleeve 130 fits over the clip seat 430. When the clip groove 131 aligns with the clip head 450, the magnetic block 440 resets, pushing the clip head into the clip groove 131 to complete the installation. This design allows the electronic tag to be removed only by magnetic attraction, effectively preventing it from being torn off by the user or others, thus ensuring effective positioning.

[0100] See Figure 15 , and Figure 14 Both are designed for tamper prevention, but their structures have been simplified, as detailed below:

[0101] The electronic tag 100 is fixed with a needle holder 710, and a needle 720 is fixed on the needle holder 710. The needle 720 is provided with an arc-shaped annular groove 721.

[0102] The pin 720 passes through the fixing object 01 and is inserted into the fixing box 730. The fixing box 730 has a hollow fixing box cavity 731 inside, and a locking component 740 is installed inside the fixing box cavity 731. The locking component 740 is provided with a latching strip 741, a diagonal strip 742, and a support spring 743. The latching strip 741 is provided with a latching protrusion 7411. One end of the diagonal strip 742 is connected to the latching protrusion 7411 or the latching strip 741, and the other end of the diagonal strip 742 is fixed to a magnet block 750. The magnet block 750 is placed on the support spring 743. Both the support spring 743 and the latching strip 741 are elastic. The magnet block 750 is made of a material that can attract magnets, such as soft iron, steel, or a magnet.

[0103] The latching protrusion 7411 engages within the arc-shaped annular groove 721 to lock the pin 720 axially upwards, preventing the pin 720 from being pulled out of the retaining box 730. Unlocking is required by adjusting the locking mechanism on the outer side of the end of the locking member 740. Figure 15 A magnet is placed below or a magnetic field is applied. The magnetic field pulls the magnet block 750 downwards, causing the latching strip 741 to bend. The latching strip 741 causes the latching protrusion 7411 to exit the arc-shaped groove 721, at which point the pin 720 can be pulled out. When the pin is inserted, the pin presses against the latching protrusion 7411, causing it to push the latching strip 741 outwards until the arc-shaped groove 721 and the latching protrusion 7411 are aligned. The latching protrusion 7411 then engages with the arc-shaped groove 721, completing the locking process.

[0104] Preferably, the latching strip 741 is further provided with a release spring 760. The release spring 760 is elastic and is initially in position 760-1. After the pin 720 is inserted, it pushes the release spring 760 downward to elastically bend and store elastic force. Once the latching protrusion 7411 exits the arc-shaped groove 721, the release spring 760 applies an elastic force to the pin 720 to push the electronic tag, so that the arc-shaped groove 721 and the latching protrusion 7411 are misaligned. At this time, even without a magnetic field, the arc-shaped groove 721 and the latching protrusion 7411 will not re-lock, thus facilitating the removal of the electronic tag.

[0105] Preferably, the entire locking element 740 can be integrally injection molded from a flexible plastic.

[0106] Figures 3-15All of them are designed to be detachable, which is mainly to prevent damage when washing clothes or getting wet, and also to facilitate replacement.

[0107] See Figure 16 When used outdoors, situations may arise such as power outages preventing the management terminal from obtaining location information, lack of reading devices, or damage to the electronic tag. In such cases, additional safety measures are necessary. To address this, this embodiment adds a miniature compass 500, which can be adhesively attached to the electronic tag 100.

[0108] See Figure 17 The electronic tag 100 has a through-hole 102, and the compass 500 has a plug-in protrusion 510. One end of the plug-in protrusion 510 passes through the plug-in hole 102, and a protruding ring 511 is provided on this end of the plug-in protrusion 510. The protruding ring 511 is elastic. When the protruding ring 511 passes through the plug-in hole 102, it undergoes elastic deformation and returns to its original shape after passing through the plug-in hole 102, thereby making it difficult for the plug-in protrusion 510 to be pulled out of the plug-in hole 102 in the opposite direction.

[0109] See Figure 18 A ring of protrusions 520 can be provided on the compass 500. The protrusions 520 are fitted into an annular groove 141, which is set on the retaining film 140. The retaining film 140 is fixed to the end face of the electronic tag 100. The retaining film 140 is preferably glued to the end face of the electronic tag 100. The protrusions 520 cannot pass through the annular groove 141, thereby realizing the assembly and fixation of the compass 500 and the electronic tag 100.

[0110] If you get lost outdoors, you can use a compass 500 to find your way and get out of danger as quickly as possible.

[0111] See Figures 17-18 In some embodiments, a temperature sensor is embedded in the electronic tag, which is then attached to the user's skin to detect the user's body temperature. The corresponding temperature value is subsequently read by a reader. This is existing technology, and the flexible electronic temperature measurement tag technology of Fudan Microelectronics Group can be referenced or adopted.

[0112] See Figure 19 A heat-insulating film 150 can be fixed to the outside of the electronic tag 100. The heat-insulating film 150 protrudes around the circumference of the electronic tag 100, forming an adhesive portion 151. Adhesive is applied to the adhesive portion 151, and it is then attached to the fixing object 01 using the adhesive. The heat-insulating film 150 is made of thermal insulation film, giving it certain thermal insulation properties, thereby improving the accuracy of body temperature detection.

[0113] See Figure 20Alternatively, an adhesive layer 160 can be applied to the inside of the electronic tag 100, and it can be attached to the fixture 01 using the adhesive layer.

[0114] This design is primarily for ease of use, and when combined with payment functionality, it can be attached to the wrist to enable wireless payment, public transportation payment, body temperature monitoring, and other functions, while also monitoring the user's health status through the body temperature monitoring function.

[0115] In some embodiments, see Figure 21 The functional part 200 is equipped with a first temperature sensor 611 and a first humidity sensor 612, respectively, and is installed inside the heat insulation film 150. The adhesive part 151 is attached to the skin, so that the first temperature sensor 611 and the first humidity sensor 612 are attached to the skin to detect body temperature and skin humidity.

[0116] See Figure 22 The functional part 200 is equipped with a second temperature sensor 621 and a second humidity sensor 622. An adhesive layer 160 is provided on the end face of the functional part 200, and the adhesive layer 160 is adhered to the outside of the clothing so that the second temperature sensor 621 and the second humidity sensor 622 face the air. This allows the second temperature sensor 621 and the second humidity sensor 622 to measure the ambient temperature and ambient humidity respectively.

[0117] The first temperature sensor 611 and the second temperature sensor 621, the first humidity sensor 612 and the second humidity sensor 622 can be thermistors and humidity sensors, respectively. Thermistors and humidity sensors are connected in series between the power supply (the antenna-coupled output current end) and the pins of the RFID chip. The resistance of the thermistors and humidity sensors changes with temperature and humidity variations. Therefore, knowing the power supply voltage and the current value obtained by the RFID chip allows for the calculation of the resistance value, and then the corresponding temperature and humidity. The voltage magnitude can be obtained using a spectrum analyzer. A spectrum analyzer is mainly used to analyze the spectral components of electrical signals, that is, to convert the time-domain electrical signal into a frequency-domain representation, displaying the power distribution of the signal at different frequencies. For the voltage signal generated by the coupled current, it can detect which frequency components the signal contains and the power and amplitude information corresponding to each frequency component. Its working principle is based on digital signal processing techniques such as Fast Fourier Transform (FFT) of the input signal, converting the signal from the time domain to the frequency domain for analysis and display. In radio frequency identification (RFID) systems, there is electromagnetic coupling between the reader and the electronic tag. To detect the frequency domain characteristics of the voltage signal generated by this coupling, the input port of a spectrum analyzer can be connected to the location to be detected (such as the coupling area near the electronic tag antenna) via a suitable RF cable. After setting the center frequency, scanning bandwidth, resolution bandwidth, and other parameters of the spectrum analyzer, the spectrum of the coupled voltage signal can be seen on the display screen, allowing for an understanding of its frequency distribution and corresponding power, thus providing a deeper understanding of the characteristics of the coupled voltage.

[0118] Of course, passive temperature and humidity measurement are already existing technologies, and this embodiment can directly adopt existing technologies, such as the flexible electronic temperature measurement tag and passive humidity measurement tag from Fudan Microelectronics Group. These are relatively mature technologies, and this embodiment can directly use existing technologies that can theoretically measure temperature and humidity. It is not necessary to be limited to the structure and principle given in this embodiment. The above solutions are optional and are not essential technical features of this embodiment.

[0119] See Figure 23 When using it, it is generally Figure 21 , Figure 22 Electronic tags are used in pairs; for ease of description, they will be... Figure 21 The electronic tag is named an internal electronic tag, and will Figure 22The electronic tag is named the external electronic tag. When in use, the internal electronic tag is attached to the inside of the clothing, ideally against the skin, while the external electronic tag is attached to the outside of the clothing. Temperature and humidity at the skin and in the environment can be collected separately, allowing for the estimation of the patient's body temperature, health status, and whether they are sweating. For example, if the body temperature is 40°C in an environment of 25°C, the patient clearly has a fever. Alternatively, if the humidity inside the clothing is significantly higher than the ambient humidity, it can be assumed that the patient is sweating. Combined with body temperature, if there is no significant increase in body temperature, it means that the humidity inside the patient's clothing has significantly increased, possibly indicating urination or menstruation. If the body temperature has significantly increased, sweating is likely present. Of course, these can be obtained through a limited number of tests. Detecting ambient temperature and humidity is of great significance for subsequent location tracking. This design can be integrated with a monitoring system to achieve passive location tracking and health status monitoring of the monitored individual.

[0120] During normal use, a QR code can be printed on the functional part 200. By scanning and recognizing the ID of the QR code, it can be bound to the ID of the electronic tag. The ID of the electronic tag can then be bound to the user's ID, so that the ID of the electronic tag represents the user's ID.

[0121] In this embodiment, the fixing object is determined according to the actual situation. For some scenarios that require puncture or where parts are fixed on the fixing object, it is obviously not suitable to use skin. This is basic common sense.

[0122] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this application pertains.

[0123] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
