Description

Technical Field

[0001] This utility model relates to the field of radio frequency identification technology, specifically to a passive energy storage luminescent electronic tag. Background Technology

[0002] Radio Frequency Identification (RFID) is an automatic identification technology. RFID acquires relevant data about objects through wireless radio frequency signals and identifies them. RFID technology can complete the input and processing of object information without direct contact with the object being identified, enabling fast, real-time, and accurate collection and processing of object information.

[0003] RFID uses electronic tags to identify objects. Each electronic tag contains an electroluminescent driver chip and an antenna. The chip stores the object's data, while the antenna transmits and receives radio waves. The tag's antenna transmits the object's data to a nearby RFID reader, which then receives and processes the data. RFID requires no human intervention, can operate in various harsh environments, can identify high-speed moving objects, and can simultaneously identify multiple targets.

[0004] Currently, UHF LED-driven tags on the market mainly come in two types: passive and active. Passive LED tags require an external electromagnetic field to activate and provide sufficient energy to drive the LEDs, which limits the illumination distance. The effective illumination distance of passive LED tags is generally no more than 3 meters, and the light brightness is relatively weak. Active LED-driven tags require battery power to drive the LEDs. While this can improve the illumination distance and brightness, the batteries are bulky, have short lifespans, and need to be replaced regularly. Utility Model Content

[0005] To address this, this invention provides a passive energy storage luminous electronic tag that integrates a micro energy storage capacitor or a super energy storage capacitor to temporarily store the sensed electrical energy, providing power to the luminous tag. The luminous driving chip collects and stores the electromagnetic wave energy emitted by the reader into the energy storage capacitor. When the LED indicator light is needed, the energy is released from the energy storage capacitor, improving the lighting distance and brightness of the luminous tag and achieving the goal of a battery-free and maintenance-free ultra-high frequency luminous driving tag.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A passive energy storage luminescent electronic tag includes an encapsulation shell, a radio frequency antenna, a light-emitting driver chip, an LED indicator, and an energy storage capacitor. The radio frequency antenna is disposed within the encapsulation shell and electrically connected to the light-emitting driver chip. The light-emitting driver chip is disposed within the encapsulation shell and mounted on the radio frequency antenna. The LED indicator is disposed within the encapsulation shell, mounted on the radio frequency antenna, and electrically connected to the light-emitting driver chip. The energy storage capacitor is disposed within the encapsulation shell, mounted on the radio frequency antenna, and electrically connected to the light-emitting driver chip. The encapsulation shell is provided with a light-transmitting plate corresponding to the LED indicator.

[0008] Furthermore, the encapsulation shell is integrally injection molded with an IP68 airtightness rating.

[0009] Furthermore, the radio frequency antenna is a single-sided rigid glass fiber copper-clad laminate.

[0010] Furthermore, the light-emitting driver chip is in a DFN package; the LED indicator is in a 3528 package with a built-in high-brightness reverse polarity LED bead; and the energy storage capacitor is in a 0603 package.

[0011] Furthermore, the radio frequency antenna is provided with mounting holes for fixing the light-transmitting plate.

[0012] Furthermore, the radio frequency antenna is provided with a balancing hole.

[0013] This utility model has the following advantages:

[0014] The passive energy storage luminescent electronic tag provided by this utility model has an RF antenna that can receive RF signals emitted by the reader and transmit them to the luminescent driver chip. At the same time, the RF antenna can also transmit the data signals in the luminescent driver chip back to the reader. The luminescent driver chip is used to store and transmit relevant information about the cable. The LED indicator can be powered on to emit light. The energy storage capacitor can provide instantaneous energy to improve the brightness of the LED indicator.

[0015] These electronic tags are applied to cable assets such as cable tunnels, cable trenches, and power wells. Through RFID technology, a one-to-one relationship is established between on-site cables and channels and the cable and channel information in the power cable management system. This enables functions such as personnel on-site inspections, assisting in various mobile operations including patrol inspections, maintenance, emergency repairs, hazard identification, defect handling, fault location, and testing. This achieves large-scale digital management of cable assets and improves the level of lean management of power cables. The light emitted by the LED indicator lights can be used for quick cable location, improving cable finding efficiency.

[0016] The enclosure is made of one-piece injection molding, which completely seals the entire RF antenna in the enclosure material, achieving an IP68 airtightness rating. This protects the internal electronic components and allows the product to be used for more than 10 years in harsh outdoor environments.

Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0024] like Figure 1 and 2As shown, this embodiment provides a passive energy storage luminescent electronic tag, including a housing 1, an RF antenna 2, a light-emitting driver chip 3, an LED indicator 4, and an energy storage capacitor 5. The RF antenna 2, light-emitting driver chip 3, LED indicator 4, and energy storage capacitor 5 are collectively referred to as electronic devices. The RF antenna 2 is disposed within the housing 1 and electrically connected to the light-emitting driver chip 3; the light-emitting driver chip 3 is disposed within the housing 1 and mounted on the RF antenna 2. The LED indicator 4 is disposed within the housing 1, mounted on the RF antenna 2, and electrically connected to the light-emitting driver chip 3. The energy storage capacitor 5 is disposed within the housing 1, mounted on the RF antenna 2, and electrically connected to the light-emitting driver chip 3. The housing 1 is provided with a light-transmitting plate corresponding to the LED indicator 4.

[0025] Specifically, the light-emitting driver chip 3 has six pins: RF1, RF2, LED, VCC, GND, and OS. RF1 and RF2 are radio frequency input / output ports. LED is connected to LED indicator 4. VCC is connected to energy storage capacitor 5. GND is ground or grounded. OS is for open circuit detection. The radio frequency antenna 2 is connected to the RF1 and RF2 ports of the light-emitting driver chip 3. One end of LED indicator 4 is connected to the LED port of the light-emitting driver chip 3, and the other end is connected to the GND port of the light-emitting driver chip 3. One end of energy storage capacitor 5 is connected to the VCC port of the light-emitting driver chip 3, and the other end is connected to the GND port of the light-emitting driver chip 3. The energy storage capacitor 5 and LED indicator 4 are connected in parallel.

[0026] The encapsulation shell 1 is made of high-performance plastic and is injection molded using a one-time injection molding process to encapsulate the RF antenna 2 inside. It has an IP68 airtightness rating and can withstand temperatures above 125°C.

[0027] Furthermore, the radio frequency antenna 2 is a single-sided rigid glass fiber copper-clad laminate, with copper as the conductive layer, which is composited, pressed, and etched.

[0028] The light-emitting driver chip 3 is in a DFN package, which facilitates SMT soldering.

[0029] LED indicator 4 is a 3528 package with built-in high-brightness reverse polarity LED beads. Compared with ordinary LEDs, high-brightness LED beads have higher luminous intensity and better visual effect, which can significantly improve the brightness of the label.

[0030] The energy storage capacitor 5 is a 0603 package, with a capacitance range of 47nF-100nF.

[0031] The radio frequency antenna 2 is provided with a rectangular mounting hole 6. A part of the light-transmitting plate is fixed (installed) in the mounting hole 6. A part of the light guide plate is located directly above the LED indicator 4. The material of the light guide plate can be high-transmittance PP material to increase the brightness of the LED indicator 4.

[0032] The radio frequency antenna 2 is equipped with multiple balance holes 7 to ensure that the glue flow between the upper and lower layers of the outer shell is balanced during one injection molding process, and the position of the radio frequency antenna 2 is balanced.

[0033] The passive energy storage luminescent electronic tag provided in this embodiment has the following functions or advantages:

[0034] 1. This luminous electronic tag can acquire energy using the radio frequency (RF) signals emitted by the reader, converting the RF signals into electrical energy and storing it in a chip and a storage capacitor. When locating a specific cable or equipment among a large number of targets, workers only need to use an RFID handheld reader to scan nearby cables and select the EPC (Electronic Product Code) of the tag to be searched. Once the RFID reader approaches the target cable, the LED on the electronic tag will flash, equivalent to the reader transmitting a specific command to control the LED circuit to light up the LED indicator. The received RF energy can be stored in the storage capacitor. When needed, the electrical energy is released from the storage capacitor, causing the LED indicator to emit a brighter light, thus clearly identifying the specific cable or equipment in the cable trench. This highly visible identification helps workers quickly and accurately locate target cables or equipment in dimly lit or complex cable trench environments, improving work efficiency. By observing the position and status of the luminous tag, the target cable can be quickly located, greatly reducing the time spent searching for cables in the cable trench and improving work efficiency.

[0035] 2. In cable trenches, cables are often intricately intertwined. Traditional management methods require manual inspection of the identification codes on the cables, which is not only time-consuming and labor-intensive but also prone to errors. The application of this luminous electronic tag allows information such as the cable's start and end points and length to be written into the tag and linked to the cable information. This enables staff to quickly identify and collect information from cables using RFID handheld devices, facilitating the recording, updating, and querying of cable information. This simplifies the cable management process, significantly reduces workload and error rates, and improves management efficiency and accuracy.

[0036] 3. This luminous electronic tag is made using a one-time injection molding process. Compared with tags made using traditional ultrasonic processes, the reliability and service life of the tag are greatly improved. The one-time injection molding process, through a special process design, completely seals the radio frequency antenna in the shell material, achieving an airtightness rating of IP68 while also withstanding high temperatures above 125°C, allowing the product to be used for more than 10 years in harsh outdoor environments.

[0037] 4. This luminous electronic tag is equipped with an energy storage capacitor (which stores electricity after receiving radio frequency signals), enabling it to emit light when the power is insufficient (and then discharge to make the LED indicator light up), thus ensuring that the tag can still emit light stably after many years of use, improving its practicality and reliability.

[0038] 5. This luminous electronic tag can be customized according to the customer's actual needs. For example, the size, shape, color, and luminous effect of the tag can all be adjusted according to the customer's requirements. It can also print or engrave content such as cable information, barcodes, or QR codes on the tag surface. It has a certain degree of scalability and can be upgraded and improved with the continuous development of technology. It can be used not only in cable corridors, but also in various scenarios such as chassis and cabinet cable management, jewelry inventory, emergency evacuation routes, and library management, with broad application prospects.
