For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0028] Referring to Figure 1 , in an embodiment of the present utility model, an RFID tag is provided, including: a packaging layer, a protective layer, and a tag adsorption layer; wherein, the packaging layer is used to package an RFID chip and an RFID antenna, the protective layer is disposed on the outer surface of the packaging layer, the materials of the packaging layer and the protective layer are flexible materials, the tag adsorption layer includes a plurality of magnetic components, and the plurality of magnetic components are arranged at intervals of a target distance in a vertical arrangement on the inner surface of the protective layer.

[0029] As Figure 1 shown, the RFID chip 2 and the RFID antenna 3 are encapsulated inside the packaging layer, and the protective layer 1 can be used to protect the electronic components (i.e., the RFID chip 2) and the antenna (i.e., the RFID antenna 3) in the RFID tag. Therefore, the protective layer 1 can be disposed on the outer surface of the packaging layer to wrap the packaging layer. In addition, as Figure 1 shown, a tag adsorption layer can also be provided. For example, in order to consider the adsorption stability of the RFID tag, a tag adsorption layer can be disposed on the inner surface of the protective layer 1. In addition, the tag adsorption layer can also be disposed on the outer surface of the protective layer 1, and the present disclosure does not make specific limitations on this, as long as it can be achieved.

[0030] In the embodiments of the present disclosure, the material of the protective layer can be selected as a flexible material that can be bent, so as to be adapted to the surface of the bent iron tower. For example, silica gel can be selected. In addition, other flexible materials that can be bent can also be selected, or other materials that can replace silica gel can be selected. Here, it can also be required that the material of the protective layer has the characteristics of corrosion resistance, waterproofing and dustproofing. Regarding the color of the protective layer, it can be set according to the actual needs of the user. For example, in order to maintain the overall aesthetics, the color of the protective layer is the same as the placement surface.

[0031] In the embodiments of the present disclosure, the material of the encapsulation layer is also a flexible material to meet the bending requirements. For example, the material of the encapsulation layer can be an ultra-thin PET flexible material. In addition, other flexible materials that can replace the ultra-thin PET flexible material can also be used.

[0032] Here, the flexibility of the materials of the protective layer and the encapsulation layer can be determined according to the usage scenario of the RFID tag. For example, if the usage scenario of the RFID tag requires a large bending angle, a material with a higher flexibility can be selected; for another example, if the usage scenario of the RFID tag does not require a large bending angle, a material with a smaller flexibility can be used. In addition, the materials of the protective layer and the encapsulation layer can also be determined according to the installation environment of the RFID tag. For example, if the installation environment of the RFID tag is indoors, no specific requirements need to be made for the corrosion resistance, waterproofing and dustproofing of the material; for another example, if the installation environment of the RFID tag is outdoors, a material that can be bent and has the characteristics of corrosion resistance, waterproofing and dustproofing needs to be selected.

[0033] As Figure 1 shown, the tag adsorption layer includes a plurality of magnetic components 6. Among them, the component sizes of the plurality of magnetic components 6 can be the same or different; and the shapes and magnetic forces of the magnetic components can be the same or different. The plurality of magnetic components are arranged at intervals of a target distance in a vertical arrangement on the inner surface of the protective layer. Among them, the target distance between adjacent magnetic components can be the same or different. For example, starting from the center of the RFID tag, the target distance between adjacent magnetic components gradually decreases. For another example, the target distance between any adjacent magnetic components is the same.

[0034] In the embodiments of the present disclosure, the RFID chip is located at the center of the RFID tag, the RFID antenna surrounds the RFID chip, and the operating frequency of the RFID chip is different from the mobile communication frequency.

[0035] As Figure 1 shown, the RFID chip 2 is located at the center of the RFID tag and is responsible for storing and processing data. The RFID chip 2 can use an RFID chip with a frequency of 920 MHz - 925 MHz to avoid interference with the mobile communication frequency. As Figure 1As shown, the RFID antenna 3 surrounds the chip and is responsible for receiving and sending wireless signals. Here, a metal-resistant flexible RFID antenna can be used, which has strong bending resistance. Its size is appropriately increased to improve the gain and ensure that the identification distance of the reader reaches more than 8 meters. Here, the models and types of the RFID chip 2 and the RFID antenna 3 are not specifically limited as long as they can achieve the function.

[0036] In an alternative embodiment, the RFID tag includes: a marking layer; wherein, the marking layer is disposed on the outer surface of the protective layer, and the marking layer is provided with the identification information of the RFID tag.

[0037] Refer to Figure 1 , the marking layer 7 is disposed on the outer surface of the protective layer 1, and the marking layer 7 is provided with the identification information of the RFID tag. Here, the marking layer 7 can be customized during the procurement stage. Through this customization, the marking layer can display obvious words or marks, thereby ensuring that the handwriting or identification is clearly visible and the recognition degree can be maintained for a long time.

[0038] As Figure 1 shown, the marking layer 7 is disposed on the outer surface of the protective layer away from the tag adsorption layer. In addition, the marking layer 7 can also be disposed at other positions. For example, the marking layer 7 can be disposed on the two side surfaces of the protective layer perpendicular to the tag adsorption layer. Here, the marking layer 7 can be pasted on the outer surface of the protective layer, or can be snap-connected to the outer surface of the protective layer through a buckle, or can be disposed on the outer surface of the protective layer by welding.

[0039] In an alternative embodiment, as Figure 1 shown, the RFID tag includes: an adhesive layer 8, and the adhesive layer 8 is disposed on one side of the outer surface of the protective layer 1 close to the tag adsorption layer, and the adhesive layer 8 is provided with a release paper 9.

[0040] As Figure 1 shown, the adhesive layer 8 can be pre-set below the protective layer 1 in advance. Among them, the size of the adhesive layer 8 is slightly smaller than the size of the RFID tag to avoid affecting the smooth detachment of the tag from the pasting device. In the embodiments of the present disclosure, the material of the adhesive layer 8 can be acrylic glue that can be condensed and has good compatibility with the material of the pasting surface. This material has better adaptability to various pasting surfaces to ensure the firm adhesion of the tag. In addition, the material of the adhesive layer 8 can also be selected as a material that can paste the RFID tag in the corresponding usage scenario, or can be selected as other materials that can replace acrylic glue. The present disclosure does not make specific limitations on this as long as it can achieve the function. Here, the release paper 9 is provided on the adhesive layer 8 to protect the adhesive layer 8. During the pasting and placing operation, it needs to be torn off in advance to expose the adhesive layer 8.

[0041] In an alternative embodiment, the plurality of magnetic components are a plurality of rectangular magnets, and the plurality of rectangular magnets are arranged in parallel in the vertical direction on the inner surface of the protective layer, and the width of the magnet located at the RFID chip portion among the plurality of rectangular magnets is greater than the width of the remaining magnets.

[0042] Referring Figure 2 , Figure 2 FIG. shows a top view of the label adsorption layer in the RFID tag. The plurality of magnetic components 6 can be selected as a plurality of rectangular magnets. The plurality of rectangular magnets are arranged in parallel in the vertical direction on the inner surface of the protective layer 1, and the width of the magnet located at the RFID chip 2 portion among the plurality of rectangular magnets is greater than the width of the remaining magnets.

[0043] In the embodiment of the present disclosure, the magnetic components in the label adsorption layer can be made of a permanent magnet material (such as ferrite) to provide the magnetic adsorption function of the label. By this design method, while improving the adsorption ability of the label to the tower surface, the magnetic field interference to the RFID can be reduced, thereby improving the recognition sensitivity.

[0044] As Figure 2 shown, the plurality of magnetic components are distributed in a manner similar to the "ribs" of a folding fan, composed of multiple rectangular magnets, spaced at a certain distance, and fixed on the back of the label encapsulation material in a parallel arrangement in the vertical direction. By this layout method, the ability of the RFID tag to adapt to the curved tower surface is enhanced. At the same time, the magnet at the RFID chip portion is appropriately widened to strengthen the protection of the chip portion. Here, the interval between the plurality of magnetic components needs to be appropriate and cannot be too small to avoid too large a bending angle of the label.

[0045] From the above description, it can be seen that the working principle of the RFID tag provided by the present utility model is:

[0046] The RFID tag provided by the present utility model is adsorbed on the target communication device by the plurality of magnetic components 6 in the label adsorption layer 5 in a magnetic adsorption manner. The plurality of magnetic components 6 are arranged in parallel in the vertical direction on the inner surface of the protective layer 1 at a preset interval, and the materials of the encapsulation layer 4 and the protective layer 1 are both flexible materials, enhancing the ability of the RFID tag to adapt to the curved tower surface. At the same time, the layout width of the rectangular magnet corresponding to the RFID chip 2 position among the plurality of magnetic components 6 is greater than the width of the remaining magnets, which can strengthen the protection of the RFID tag for the RFID chip 2.

[0047] The RFID tag provided by the present utility model can also be fixed on the communication device by pasting. Specifically, the release paper 9 provided on the adhesive layer 8 is torn off, so that the acrylic adhesive on the adhesive layer 8 comes into contact with the surface of the target communication device. The length of the adhesive layer 8 can be less than the length of the protective layer 1 to avoid affecting the smooth detachment of the RFID tag from the delivery device. After installation, the flexible materials of the encapsulation layer 4 and the protective layer 1 can be adaptively bent according to the surface shape of the target communication device, and play a protective role for the RFID chip 2 and the RFID antenna 3. The marking layer 7 is used for the later maintenance of the RFID tag. The marking layer 7 can maintain the recognition degree of the RFID tag for a long time, facilitating the inspection and maintenance by the staff.

[0048] In an embodiment of the present utility model, a delivery system is provided, as Figure 3 shown. The delivery system includes: a delivery device 100 and an RFID tag 200 to be delivered. Among them, the structure of the RFID tag 200 to be delivered is the same as that of the RFID tag described in the above embodiment. The delivery device 100 is fixed on the unmanned aerial vehicle, and the RFID tag 200 to be delivered is arranged on the delivery device 100. The delivery device 100 is used to fixedly paste the RFID tag to be delivered on the target communication device under the carrying of the unmanned aerial vehicle.

[0049] Here, the delivery system can be fixed to the fuselage of the unmanned aerial vehicle, and the RFID tag 200 to be delivered can be pasted and adsorbed on the metal surface position of the high tower through the unmanned aerial vehicle. Considering the safety distance of the unmanned aerial vehicle, the technical solution of the present disclosure can adopt the scheme of lengthening the push arm. After the unmanned aerial vehicle reaches the target position, the delivery system can fixedly paste the RFID tag to be delivered on the target communication device according to the remote control instruction sent by the remote controller on the ground, and complete the pasting and adsorption of the tag.

[0050] In an alternative embodiment, referring to Figure 4 , Figure 4 an exemplary structural schematic diagram of the delivery device is shown. The delivery device includes: an electric push device 10, a control system, and a tag bracket 11. Among them, the control system is electrically connected to the electric push device 10, the electric push device 10 is mechanically connected to the tag bracket 11, the tag bracket 11 is used to place the RFID tag to be delivered, and the control system is used to control the movement of the electric push device 10 according to the remote control instruction, so that the electric push device 10 pushes the RFID tag to be delivered arranged on the tag bracket 11 to be fixedly pasted on the target communication device.

[0051] In the embodiments of the present disclosure, ground control personnel can issue remote control instructions through a remote controller. The receiver is connected to the control system, and the control system can control the electric propulsion device to move forward according to the remote control instructions of the ground control personnel, thereby pushing the label bracket carrying the RFID tag to be delivered towards the target communication device, and then fixedly attaching the RFID tag to be delivered on the target communication device.

[0052] Here, the control system can receive remote control instructions, thereby realizing the extension and retraction of the electric propulsion device, and can also turn on or off the power required for the electromagnet. A circuit is provided in the control system, and through this circuit, the external power supply interface of the unmanned aerial vehicle can be connected to provide stable direct current. The control system can also consider docking with the control system of the unmanned aerial vehicle.

[0053] Further, the electric propulsion device 10 includes: an electric push rod 12 and a push arm 13. Among them, the electric push rod 12 is mechanically connected to the push arm 13, and the control system drives the push arm 13 to move by controlling the electric push rod 12.

[0054] In the embodiments of the present disclosure, a push arm can be equipped on the delivery system, and the control system can drive the push arm through a micro DC electric push rod. After the unmanned aerial vehicle reaches the target height position, push the RFID tag to be delivered against the surface of the target communication device and provide a certain pressure, so that the adhesive layer is effectively pasted on the surface of the target communication device. After the label delivery is completed, after the electromagnet is turned off, retract the push arm.

[0055] To adapt to the unmanned aerial vehicle, the push arm needs to have a certain length, and the push arm and the label bracket are required to be light in weight and high in strength. The micro DC electric push rod has a push rod stroke matching the label bracket and sufficient push rod pressure calibration to ensure that the label can be accurately pasted at the specified position.

[0056] Further, the label bracket 11 includes: a groove bracket 15 and an electromagnet 14. Among them, the electromagnet 14 is arranged in the bottom area of the groove bracket 15 and contacts the RFID tag to be delivered, and an opening is provided at the bottom end of the groove bracket 15, and the push arm 13 of the electric propulsion device 10 is electromagnetically connected to the electromagnet 14 through the opening.

[0057] In the embodiments of the present disclosure, as Figure 4 shown, the electromagnet is installed outside the push arm or in the bottom area of the groove bracket 15. The electromagnet can contact the RFID tag to be delivered through the groove bracket 15. When turned on, the electromagnet 14 can adsorb the magnetic component of the RFID tag to be delivered to ensure that the tag is firmly adsorbed during the takeoff of the unmanned aerial vehicle. After the label delivery is completed, turn off the electromagnet 14 to release the RFID tag to be delivered. Here, the electromagnet 14 needs to select an appropriate size, shape and magnetic field strength and have sufficient adsorption force to keep the label stable.

[0058] In an embodiment of the present disclosure, a groove bracket 15 may be provided at the other end of the push arm 13. Wherein, the contact surface of the groove bracket 15 with the tag to be delivered may be a plane; in addition, different bending angles may be set according to the usage scenario of the RFID tag (for example, the type of the target communication device).

[0059] Here, the groove bracket 15 can be detachably arranged at the other end of the push arm 13. Different models can be preset for the groove bracket, so that the corresponding groove bracket can be replaced according to the usage requirements to adapt to the iron tower with a horizontal or curved surface. By providing a tag bracket in the shape of a groove, the RFID tag can be embedded in the bracket to prevent the tag from being affected by the airflow and detaching from the electromagnet during the UAV delivery stage. A foam can be arranged on the contact surface between the groove bracket and the RFID tag to disperse the pressure of the push arm, making the force on the tag more uniform and gentle during the pasting process.

[0060] In an alternative embodiment, the number of electromagnets 14 is multiple, and the installation positions of the electromagnets 14 on the tag bracket 11 correspond to the positions of the magnets of the RFID tag to be delivered.

[0061] In an embodiment of the present disclosure, the RFID tag to be delivered can be placed in the groove bracket 15, and then the electromagnet 14 is energized to fix the RFID tag in a magnetic adsorption manner. Then, the control system drives the push arm 13 to move by pushing the electric push rod 12, so that the RFID tag to be delivered arranged on the tag bracket 11 reaches the specified delivery position. When the RFID tag to be delivered reaches the specified delivery position, the power supply of the electromagnet 14 is disconnected, so that the RFID tag to be delivered is fixedly attached to the target communication device through the tag adsorption layer 5.

[0062] It should be noted that the RFID tag can also be fixedly attached to the target communication device through the adhesive layer 8, or the RFID tag can be fixedly attached to the target communication device by combining the adhesive layer 8 and the tag adsorption layer 5. The specific combination method is not limited here.

[0063] After the RFID tag is fixedly attached to the target communication device, the tag information of the RFID tag can be read through an RFID reader.

[0064] In an embodiment of the present disclosure, a UHF RFID handheld device can be used. The UHF RFID handheld device combines flexibility and portability, is suitable for outdoor scenarios, and has characteristics such as waterproof, dustproof, and anti-drop. In addition to the data acquisition function of a high-power RFID reader, it also has wireless communication capabilities, supports inserting a SIM card to connect to the mobile network, and can also be connected to a mobile phone or laptop computer through a wireless hotspot, Bluetooth, etc. for data transmission.

[0065] When using a UHF RFID handheld device to read and write tags, pay attention to the environmental impact. You can try different reading angles and power settings, and try to shorten the distance between the RFID handheld device and the tag. When reading, hold the two sides of the device as much as possible, and do not block the back antenna part to avoid blocking between the RFID handheld device and the tag.

[0066] The backend data processing system can obtain data through its wireless connection ability with the UHF RFID handheld device, and through data storage and analysis, realize the management, tracking, and monitoring of equipment assets. The backend data processing system can be developed using the SDK development kit provided by the RFID manufacturer to form well-organized and detailed asset device data. It can also further consider connecting to the cloud management platform to achieve fast data penetration from bottom to top and provide first-hand asset data for the management platform.

[0067] In summary, the working principle of the delivery system provided by the present utility model can be specifically described as follows:

[0068] When it is necessary to deliver an RFID tag, first, collect information of the tower communication equipment in various ways, such as using a ground telescope or flying a drone into the air, and identifying the tower antenna and radio frequency equipment through a camera pan-tilt, and filling the information into a prefabricated template. Then, input the information into the backend data processing system according to the form template. After the collected data is integrated and analyzed, the backend system connects to the handheld terminal and writes the target data into the RFID tag. After that, the drone is powered on after installing the delivery device, and according to the remote control instruction, test whether the push arm 13 can be normally pushed out and retracted, and test whether the electromagnet 14 can provide magnetic adsorption. If there is any abnormality, conduct troubleshooting and repair.

[0069] After checking for no abnormalities, place the RFID tag to be delivered in the groove bracket 15 of the tag bracket 11, and energize the electromagnet 14 to fix the RFID tag in a magnetic adsorption manner, and tear off the release paper 9 on the back of the adhesive layer 8. Then, operate the drone to make the delivery device reach the designated operation area. When the delivery device reaches the designated operation area, the staff issues a remote control instruction to the control system of the delivery device to control the electric push rod 12 to make the push arm 13 move forward, so that the outer side of the tag bracket 11 gently touches the surface of the device. For a curved iron tower surface, ensure that the center point of the tower surface contacts the tag bracket 11. When contact is made, the drone remains stable, disconnect the power supply of the electromagnet 14, and make the RFID tag to be delivered be fixedly attached to the target communication device through the tag adsorption layer 5 and the adhesive layer 8. Finally, retract the push arm 13 through a remote control instruction, the drone retreats, and observe through the pan-tilt whether the RFID tag is firmly attached. After determining that it is firmly attached, the drone retreats and lands.

[0070] In another possible embodiment of the utility model, the RFID tag to be delivered can also be fixed in the groove bracket 15 by a snap-fixing method. Corresponding to this snap-fixing method, a movable push block is arranged in the tag bracket 11. When the RFID tag to be delivered reaches the designated delivery position, the RFID tag to be delivered is pushed out of the groove bracket 15 by pushing the push block, so that the RFID tag to be delivered is fixedly attached to the target communication device through the tag adsorption layer 5 or the adhesive layer 8.

[0071] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0072] (1) The RFID tag provided by the utility model can better meet the use requirements of outdoor environments, especially the equipment on iron towers.

[0073] In the technical solution of the present disclosure, first, the structure of the RFID tag is improved. From the RFID antenna to the encapsulation layer, including the protective layer, flexible materials are used, which enhances the adaptability of the RFID tag to curved surfaces. The magnetic components arranged in the "fan bone" manner have a strong magnetic adsorption ability to metal surfaces in addition to the traditional glue paste layer. Innovatively, it is proposed to divide the magnetic components into multiple rectangular magnets, with a certain distance between them, and fix them on the back of the tag encapsulation material in a vertical arrangement, which also greatly improves the ability of the tag to adapt to the curved surface of the iron tower. Among them, the magnet layer at the RFID chip part increases the horizontal width to strengthen the protection of the chip part. The strong magnet layer is located in the silica gel protective layer, which can have a more lasting magnetic attraction to the metal surface, and cooperate with the underlying acrylic glue to provide adhesion ability, improving the outdoor adsorption durability of the tag and achieving the same service life as the RFID.

[0074] (2) The cost of the delivery system provided by the utility model is relatively low. Compared with manually climbing the tower for tag delivery and inventory, the efficiency of inventory using this proposal is greatly improved, and the cost is significantly reduced.

[0075] The delivery system provided by the technical solution of the present disclosure can adapt to the structural characteristics of the above RFID tag, and can be paired with a drone to deliver tags to existing outdoor equipment, especially equipment on towers. The delivery system adds an electromagnet to match the two operation processes of adsorption and pasting; the type of tag bracket can be replaced according to the shape of the pasting surface, and brackets with flat or curved surfaces can be selected to enhance the adaptability to equipment with complex shapes such as curved surfaces. By carrying a delivery device with a drone, the RFID tag can be delivered without relying on manual tower climbing, which greatly improves the delivery efficiency. Moreover, compared with manually climbing the tower to deliver the RFID tag, the cost of using the delivery system to deliver the RFID tag is relatively low.

[0076] The inventor has statistically analyzed the delivery and asset inventory efficiency of the drone carrying the delivery device and the traditional manual tower climbing. The following table is the summary statistical table:

[0078] It can be seen from the above table that the delivery system provided by the utility model has significantly increased the average daily number of inspection sites: the number of ground tower stations increased from 4.8 stations to 7.4 stations, an increase of 54%, and the number of high mountain stations increased from 3.3 stations to 6.9 stations, an increase of 107%.

[0079] The inventor estimated the cost of using drones equipped with delivery devices and traditional manual tower climbing to place labels and take inventory. In terms of cost estimation, the labor cost is estimated at 300 yuan per day for inventory personnel and 400 yuan per day for tower workers. The estimated prices of drones, labels, and delivery devices are as follows: According to the estimation of newly purchased drones, the purchase cost of a single drone (including customized delivery devices) is 7,000 yuan, the cost of charging, maintenance and subsequent purchase of batteries is 3,000 yuan, and the purchase price of the read-write terminal is 4,000 yuan. Based on a 5-year lifespan and 200 working days per year, the drone and the read-write terminal share 14 yuan per day. Due to the long lifespan of the label, the cost of each label is calculated at 5 yuan, and the cost is estimated at 1 yuan per station for each asset inventory. The total cost of 7 stations per day is 7 yuan. The following table is a statistical table of estimated costs:

[0082] It can be seen from the above table that the use of the delivery system provided by the utility model can significantly reduce the cost of site asset inventory, from 154 yuan / station to 48 yuan / station for ground tower stations, which is 31% of the original cost, and from 217 yuan / station to 51 yuan / station for high mountain stations, which is 24% of the original cost. If the use of old drones or RFID reading terminals is considered, the cost can be further reduced. According to the volume of more than 10 million mobile base stations nationwide, the number of towers has reached millions, and the proportion of central and western provinces is significantly higher than that of the eastern plains. In summary, the cost of the delivery system provided by the utility model is low. Compared with manual tower delivery and inventory, the efficiency of inventory using this proposal is greatly improved, the cost is significantly reduced, and the commercial application prospects are broad.
