[0003] The electronic tag tracking system is a system that combines radio communication to track and locate tags. An electronic tag tracking system usually includes an electronic tag reading terminal (hereinafter referred to as a card reader) and the electronic tag to be tracked. The card reader is responsible for wireless communication directly with the electronic tag to obtain relevant information of the electronic tag, such as: tag identification (ID), received signal strength (Received Signal Strength Indicator, referred to as RSSI). The card reader has independent calculation and storage functions, and can obtain the location information of the electronic tag by obtaining the RSSI of the electronic tag and store the location information. The electronic tag usually includes a tag processing chip and a tag antenna. The structure of electronic tags using different wireless transmission protocols will be different. For example: electronic tags using passive radio frequency identification (RFID) technology do not require a power supply, so the electronic tag consists of a tag chip and a tag antenna. Electronic tags designed using other wireless technologies require microprocessors, power managers, power supplies and other devices.

[0057] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0058] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0059] At present, the technical problem that needs to be solved urgently for electronic tags used in item tracking is: the service life. The service life of electronic tags is mainly limited by the battery capacity inside the electronic tags. If the battery capacity is exhausted, the electronic tag will not be able to communicate with the card reader, and thus the item tracking function cannot be realized.

[0060] Passive RFID is an electronic tag that does not require a power source. This type of electronic tag converts the radio frequency energy emitted by the card reader into internal power supply. Therefore, this type of electronic tag is usually composed of a tag antenna and a tag chip, without the need for a built-in battery. From a theoretical point of view, as long as the electronic tag is not physically damaged, the electronic tag can be used permanently. However, the card reader required in the RFID system provided in the related art is still a special device, which lacks wireless transmission protocols such as Bluetooth and wireless fidelity (WIFI) that are widely used in consumer electronic terminals (such as smartphones and tablets). In addition, the RFID card reader is large in size and expensive, making it difficult to apply to consumer-level applications. That is, it is obviously not practical to expect consumers to carry a bulky and expensive special device specifically for electronic tag tracking. Therefore, the RFID system is mainly suitable for enterprise-level application scenarios, such as item tracking in the logistics field.

[0061] One type of consumer-grade electronic tag that is widely used in the market currently has a maximum service life of 3 years and a replaceable battery. However, during the use of the electronic tag, it is impossible to fully judge the remaining battery power. If the battery of the electronic tag is not replaced in time after a period of use, and the item is stolen in this case, it is very likely that the electronic tag will lose its tracking function due to the rapid depletion of the battery. Although electronic tag manufacturers can set battery replacement reminders, it is still difficult to ensure that users can replace the battery on time, and it is also impossible to ensure the long-term tracking function after the item is stolen.

[0062] As for another type of consumer-level electronic tags currently available on the market, they mainly use Bluetooth Low Energy (BLE) technology. BLE technology is a low-power application of Bluetooth technology. Compared with traditional Bluetooth technology, BLE can reduce chip power consumption by using different channels and encoding and decoding methods. However, the use time of this type of electronic tag is also limited to 2-3 years, which is far less than that of Passive RFID electronic tags. The purpose of applying BLE technology is to adapt to consumer electronic terminals that generally use BLE.

[0063] It can be seen that the most obvious way to increase the usage time of electronic tags is to increase the battery capacity. However, since the battery capacity is proportional to the volume of the electronic tag, the use of a large-capacity battery will inevitably increase the volume of the electronic tag, thereby affecting the practicality and aesthetics of the product.

[0064] In addition, although extending the signal transmission cycle of the electronic tag and reducing the signal transmission frequency can also reduce power consumption and thus increase the usage time (for example, an electronic tag that sends a signal every 20 seconds can theoretically reduce the power consumption by half compared to an electronic tag that sends a signal every 10 seconds), reducing the signal transmission frequency will reduce the probability of the electronic tag being discovered, thereby seriously affecting the user experience.

[0065] In summary, the related art lacks an electronic tag that is suitable for the consumer market and can be used for a long time.

[0066] The technical solution of the embodiment of the present invention can be applied to various communication systems, for example: Global System of Mobile communication (GSM) system, Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (LTE) system, LTE Frequency Division Duplex (FDD) system, LTE Time Division Duplex (TDD), Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) communication system or 5G system, etc.

[0067] Exemplarily, the communication system used in the embodiment of the present invention may include an electronic tag, which may be a device that communicates with a terminal device (or communication terminal, terminal). The electronic tag may provide communication coverage for a specific geographical area and may communicate with a terminal device located in the coverage area.

[0068] The communication system also includes at least one terminal device located within the coverage of the electronic tag. As used herein, "terminal device" includes but is not limited to connection via a wired line, such as via a Public Switched Telephone Networks (PSTN), a Digital Subscriber Line (DSL), a digital cable, a direct cable connection; and / or another data connection / network; and / or via a wireless interface, such as, for a cellular network, a Wireless Local Area Network (WLAN), a digital television network such as a DVB-H network, a satellite network, an AM-FM broadcast transmitter; and / or a device of another terminal device configured to receive / send communication signals; and / or an Internet of Things (IoT) device. A terminal device configured to communicate via a wireless interface may be referred to as a "wireless communication terminal", "wireless terminal" or "mobile terminal". Examples of mobile terminals include, but are not limited to, satellite or cellular telephones; Personal Communications System (PCS) terminals that may combine cellular radiotelephones with data processing, fax, and data communications capabilities; PDAs that may include radiotelephones, pagers, Internet / intranet access, Web browsers, notepads, calendars, and / or Global Positioning System (GPS) receivers; and conventional laptop and / or palmtop receivers or other electronic devices that include radiotelephone transceivers. Terminal equipment may refer to access terminals, user equipment (UE), subscriber units, subscriber stations, mobile stations, mobile stations, remote stations, remote terminals, mobile devices, user terminals, terminals, wireless communication devices, user agents, or user devices. The access terminal can be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal device in a 5G network, or a terminal device in a future evolved PLMN, etc.

[0069] Optionally, D2D communication can be performed between terminal devices.

[0070] Optionally, the 5G system or 5G network may also be referred to as an NR system or NR network.

[0071] Optionally, the communication system may further include other network entities such as a network controller and a mobility management entity, which is not limited in the embodiment of the present invention.

[0072] It should be understood that the device with communication function in the network / system in the embodiment of the present invention can be called communication device. The communication device may include an electronic tag and a terminal device with communication function, and the electronic tag and the terminal device may be the specific devices described above, which will not be repeated here; the communication device may also include other devices in the communication system, such as other network entities such as a network controller and a mobility management entity, which is not limited in the embodiment of the present invention.

[0073] It should be understood that the terms "system" and "network" are often used interchangeably in this article. The term "and / or" in this article is only a description of the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0074] According to one embodiment of the present invention, an electronic tag is provided. Figure 1 is a structural block diagram of an electronic tag according to one embodiment of the present invention. Figure 1 As shown, the electronic tag includes: a radio frequency component and a power supply component, and the radio frequency component includes: a first electronic module and a second electronic module, and the power consumption of the second electronic module is less than the power consumption of the first electronic module. The power supply component is used to power the electronic tag; the first electronic module is used to communicate with the card reader when the remaining power of the power supply component is greater than or equal to the power threshold; the second electronic module is used to communicate with the card reader when the remaining power is less than the power threshold. As a result, the electronic tag combines two sets of electronic module architectures with high power consumption and low power consumption, and uses different electronic modules in different application scenarios.

[0075] In an optional embodiment, the first electronic module and the second electronic module may adopt either an independent chip structure or an integrated chip structure.

[0076] In an optional embodiment, the power supply component may be a battery. The first electronic module may be a classic Bluetooth module. The second electronic module may be an ultra-low power Bluetooth module. The Bluetooth module, the ultra-low power Bluetooth module and the antenna switch may be integrated into a chip or an integrated system package (System in package, referred to as SiP). The advantage of such integration is that the ultra-low power Bluetooth transceiver can be reused. In addition, the Bluetooth module and the ultra-low power Bluetooth module may also be located on independent chips.

[0077] Bluetooth 4.0 and its newer versions of Bluetooth technology include not only classic Bluetooth functions, but also BLE functions. The classic Bluetooth function can be used for traditional data transmission, and the BLE function can use beacons to transmit signals without actively connecting to the card reader so that the card reader can find the electronic tag. The power consumption of the classic Bluetooth function is about 1W, while the power consumption of the BLE function is 10-500mW. The classic Bluetooth function can be understood as a two-way communication technology. Two-way data exchange can be carried out between the electronic tag and the card reader. The BLE function can be understood as a one-way communication technology. The beacon signal emitted by the electronic tag usually contains the pre-loaded information and the tag-specific identification code specified by the BLE standard. Figure 2 FIG. 1 is a schematic diagram of communication interaction between a Bluetooth electronic tag and a card reader according to one optional embodiment of the present invention. Figure 2 As shown in the figure, in most cases, the electronic tag is in BLE mode, that is, the electronic tag transmits beacon intermittently. The card reader (for example, smart terminal) captures the beacon signal and decodes it, and then transmits control instructions through classic Bluetooth technology, such as controlling the electronic tag to ring or vibrate, so as to locate the electronic tag.

[0078] Ultra-low power Bluetooth module is another Bluetooth technology different from BLE. The power consumption of BLE is 10-500mW, while the power consumption of ultra-low power Bluetooth module is <100uW. Under the same power consumption, the estimated usage time of the electronic tag system will exceed 100 times that of the Bluetooth module. The Bluetooth module is a module that supports Bluetooth 4.0 and its later versions and contains a Bluetooth transceiver.

[0079] In an optional embodiment, the first electronic module and the second electronic module may share the same antenna, or use first and second antennas that are independent of each other. The first antenna and the second antenna are switched for use through an antenna switch. The same antenna may use a broadband antenna or a common antenna.

[0080] An RF energy capture storage device needs to be set up in the Bluetooth ultra-low power module, which is used to capture RF signals with the same spectrum as Bluetooth (i.e. 2.4-2.5GHz), such as WIFI signals. Therefore, the RF energy capture storage device can share the same antenna with the ultra-low power Bluetooth transceiver. The RF energy capture storage device can also capture other RF energy, such as 2G GSM, UMTS, LTE, 5G NR, etc. In this case, the RF energy capture storage device needs to use an antenna corresponding to the energy spectrum to be captured or use multiple antennas or broadband antennas to simultaneously capture RF energy of different frequencies.

[0081] Optionally, the electronic tag may further include: a sensing component; a sensing component for obtaining the remaining power; wherein, when the remaining power is greater than or equal to a power threshold, the first electronic module communicates with the card reader; when the remaining power is less than the power threshold, the second electronic module communicates with the card reader.

[0082] The first sensing component may be a power acquisition sensor. Figure 3 FIG. 1 is a schematic diagram of a dual-system electronic tag combining high power consumption and low power consumption according to one optional embodiment of the present invention. Figure 3 As shown, the electronic tag system includes: an antenna, an antenna switch, a Bluetooth module, an ultra-low power Bluetooth module, a microprocessor, a power manager, a power acquisition sensor and a battery.

[0083] Optionally, the electronic tag further includes: a first processing component; the sensing component and the first processing component are arranged in a first electronic module, or the sensing component, the first processing component and the first electronic module are independently arranged in the electronic tag.

[0084] The first processing component may be a microprocessor. In an optional embodiment, multiple devices inside the electronic tag may be distributed on independent chips. For example, a microprocessor, a power manager, and a power acquisition sensor may be distributed on independent chips. In an optional embodiment, multiple devices inside the electronic tag may be integrated into one chip or SiP. For example, a microprocessor, a power manager, and a power acquisition sensor may be integrated into a Bluetooth module.

[0085] Optionally, the electronic tag further includes: a second processing component; the sensing component and the second processing component are arranged in a second electronic module, or the sensing component, the second processing component and the second electronic module are independently arranged in the electronic tag.

[0086] The second processing component may be a microprocessor. In an optional embodiment, the multiple devices inside the electronic tag may be distributed on independent chips. For example, the microprocessor, the power manager, and the power acquisition sensor may be distributed on independent chips. In an optional embodiment, the multiple devices inside the electronic tag may be integrated into one chip or SiP. For example, the microprocessor, the power manager, and the power acquisition sensor may be integrated into an ultra-low power consumption Bluetooth module.

[0087] Optionally, the second electronic module includes: an energy capture and storage device; an energy capture and storage device for acquiring radio frequency energy; wherein, when the radio frequency energy meets the transmission conditions of the beacon signal, the beacon signal is transmitted by releasing the radio frequency energy, or, the radio frequency energy is converted into a beacon signal by backscattering.

[0088] Optionally, the above-mentioned second electronic module may also include: a third processing component and a transceiver; an energy capture and storage device, which is also used to release radio frequency energy to the transceiver when the radio frequency energy meets the transmission conditions of the beacon signal; a transceiver, which is used to transmit the beacon signal; and a third processing component, which is used to control the transceiver to transmit the beacon signal based on the radio frequency energy.

[0089] Similar to BLE, the ultra-low power Bluetooth module transmits a beacon signal, which contains the pre-loaded information and tag-specific identification code required by the BLE standard. The encoding method of the beacon signal is exactly the same as that of BLE, so any device that supports Bluetooth 4.0 and above can detect the beacon signal. In addition, unlike BLE, the power consumption of the ultra-low power Bluetooth module is less than one percent of that of BLE. This significant energy reduction is achieved mainly by energy absorption and backscattering. The biggest difference between these two methods is whether there is a BLE transceiver.

[0090] In an optional embodiment, the third processing component may be a microprocessor, the transceiver may be an ultra-low power Bluetooth transceiver, and the energy capture storage device may be an RF energy capture storage device. Figure 4 is a schematic diagram of the structure of an ultra-low power consumption Bluetooth module according to one optional embodiment of the present invention, such as Figure 4 As shown, the ultra-low power Bluetooth module includes: an RF capture storage device, a capacitor or a battery, an ultra-low power Bluetooth transceiver, and a microprocessor. First, the RF capture storage device collects RF energy in the surrounding environment and stores the collected RF energy in an energy carrier (for example, a capacitor, a rechargeable battery). When the energy is stored enough to transmit a BLE beacon signal, the stored energy is released to the ultra-low power Bluetooth transceiver. The ultra-low power Bluetooth transceiver transmits a beacon signal.

[0091] The method of implementing an ultra-low power Bluetooth module through RF energy harvesting theoretically does not require an external power supply. Therefore, when switching to the ultra-low power Bluetooth module, the electronic tag can continue to work. In addition, a certain amount of power can be provided to the ultra-low power Bluetooth module (that is, a separate battery is added to the ultra-low power Bluetooth module) to wake up the chip or meet ultra-low power computing needs.

[0092] Optionally, the energy capture and storage device may include: an antenna, a rectifier, a boost converter and an energy storage device, wherein the antenna is connected to the first end of the rectifier, the second end of the rectifier is connected to the first end of the boost converter, and the second end of the boost converter is connected to the energy storage device.

[0093] If energy absorption is used to achieve significant energy reduction, the ultra-low power Bluetooth module consists of a Bluetooth transceiver and an energy harvesting (Power Harvesting) storage device. Figure 5 is a schematic diagram of the structure of an energy capture storage device according to one of the optional embodiments of the present invention, such as Figure 5 As shown, the energy capture storage device may include: an antenna, a rectifier, a boost converter and an energy storage device. The energy capture storage device can effectively store energy less than -25dBm.

[0094] Optionally, the source of the radio frequency energy includes at least one of the following: radio frequency energy in the environment surrounding the electronic tag; radio frequency energy emitted by a card reader.

[0095] The sources of RF energy can generally include but are not limited to: (1) Energy recycling, that is, collecting RF energy from the surrounding environment, such as: 2G GSM, UMTS, 4G LTE, 5G NR, WIFI, etc. This energy is the energy radiated by other RF-equipped devices when working. (2) Exclusive energy, which is emitted by the card reader and its function is to provide a reliable energy source for the electronic tag, thereby obtaining relevant information of the electronic tag.

[0096] Optionally, the second electronic module may further include: a fourth processing component; an energy capture storage device for acquiring radio frequency energy emitted by the card reader; a fourth processing component for converting radio frequency energy into a beacon signal by backscattering and feeding back the beacon signal to the card reader.

[0097] In an optional embodiment, the fourth processing component may be a microprocessor, and the energy capture storage device may be an RF energy capture storage device. When a backscattering method is used to achieve a significant energy reduction, there is no ultra-low power Bluetooth transceiver in the ultra-low power Bluetooth module. Figure 6 is a schematic diagram of the backscattering principle according to one optional embodiment of the present invention, such as Figure 6As shown, the ultra-low power Bluetooth module does not have an ultra-low power Bluetooth transceiver, but uses the backscattering principle to convert the collected RF energy into a BLE beacon signal.

[0098] The backscattering principle is similar to that of a radar system, where the card reader transmits a continuous wave (CW) signal to the electronic tag. The electronic tag uses passive reflection to feed the signal back to the card reader, and modulates the signal by changing the resistance. Due to the lack of a transmitter, the required energy is significantly reduced, and only a small amount of electricity is required to maintain its encoding function. After repeated tests for many times, the results show that the energy required for this method will be less than 1 / 100 of that of traditional BLE. It should be noted that the implementation of this method requires a stable CW signal with a specific frequency. The source of the CW signal can be either a smart terminal or a dedicated device for transmitting CW signals.

[0099] Optionally, the radio frequency component may further include: a third electronic module; the third electronic module is used to obtain the location information of the electronic tag.

[0100] In an optional embodiment, in addition to the Bluetooth module, a third electronic module may be integrated into the electronic tag, for example, Ultra-Wide Bandwidth (UWB for short). Figure 7 FIG. 1 is a schematic diagram of an electronic tag structure integrating UWB, Bluetooth, and Bluetooth ultra-low power consumption according to one optional embodiment of the present invention. Figure 7 As shown, the electronic tag integrated with UWB can use UWB to achieve accurate positioning of close-range objects (the electronic tag is set on the object), and use Bluetooth and Bluetooth ultra-low power modules to achieve fuzzy positioning of objects (for example: whether the object exists, the distance between the object and the card reader, but the exact location cannot be determined).

[0101] According to one embodiment of the present invention, a method for processing an electronic tag is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0102] In this embodiment, a processing method running on the above electronic tag is provided. Figure 8 is a flow chart of a method for processing an electronic tag according to one embodiment of the present invention. Figure 8 As shown, the method comprises the following steps:

[0103] Step S80, obtaining the remaining power of the power supply component, wherein the power supply component is used to supply power to the electronic tag;

[0104] Step S82, when the remaining power is greater than or equal to the power threshold, enable the first electronic module to communicate with the card reader; when the remaining power is less than the power threshold, switch to the second electronic module to communicate with the card reader; wherein the power consumption of the second electronic module is less than the power consumption of the first electronic module.

[0105] Through the above steps, the remaining power of the power supply component can be obtained, and the power supply component is used to power the electronic tag. When the remaining power is greater than or equal to the power threshold, the first electronic module is enabled to communicate with the card reader, and when the remaining power is less than the power threshold, the second electronic module is switched to communicate with the card reader, and the power consumption of the second electronic module is less than the power consumption of the first electronic module. The purpose of significantly increasing the usage time of the electronic tag is achieved, thereby achieving the technical effect of not only providing an electronic tag suitable for the consumer market, but also ensuring that the usage time of the electronic tag provides users with reliable item tracking guarantees, thereby solving the technical problem in the related art of lacking an electronic tag that is suitable for the consumer market and can be used for a long time.

[0106] Fig. 9 FIG. 1 is a flow chart of a dual-system electronic tag using process combining high power consumption and low power consumption according to one optional embodiment of the present invention. Fig. 9 As shown, the switching between the Bluetooth module and the ultra-low power Bluetooth module depends on the remaining battery power. The process may include the following processing steps:

[0107] Step S902, monitoring the remaining power of the battery and obtaining a monitoring result;

[0108] Step S904, judging whether the remaining power of the battery is lower than a preset percentage (e.g., n%) according to the monitoring result, if not, proceeding to step S906; if yes, proceeding to step S908;

[0109] Step S906, when the remaining battery power is greater than or equal to n%, continue to use the Bluetooth module;

[0110] Step S908: when the remaining battery power is lower than n%, switch to the ultra-low power consumption Bluetooth module.

[0111] Optionally, in step S82, switching to the second electronic module to communicate with the card reader may include the following execution steps:

[0112] Step S821, obtaining radio frequency energy;

[0113] Step S822: When the radio frequency energy meets the transmission condition of the beacon signal, transmit the beacon signal.

[0114] Similar to BLE, the ultra-low power Bluetooth module transmits a beacon signal, which contains the pre-loaded information and tag-specific identification code required by the BLE standard. The encoding method of the beacon signal is exactly the same as that of BLE, so any device that supports Bluetooth 4.0 and above can detect the beacon signal. In addition, unlike BLE, the power consumption of the ultra-low power Bluetooth module is less than one percent of that of BLE. This significant energy reduction is achieved mainly by energy absorption and backscattering. The biggest difference between these two methods is whether there is a BLE transceiver.

[0115] In an optional embodiment, the ultra-low power Bluetooth module includes: an RF capture storage device, a capacitor or a battery, an ultra-low power Bluetooth transceiver, and a microprocessor. First, the RF capture storage device collects RF energy in the surrounding environment and stores the collected RF energy in an energy carrier (for example, a capacitor, a rechargeable battery). When the energy is stored enough to transmit a BLE beacon signal, the stored energy is released to the ultra-low power Bluetooth transceiver. The ultra-low power Bluetooth transceiver transmits a beacon signal.

[0116] Optionally, the source of the radio frequency energy includes at least one of the following: radio frequency energy in the environment surrounding the electronic tag; and radio frequency energy emitted by a card reader.

[0117] The sources of RF energy can generally include but are not limited to: (1) Energy recycling, that is, collecting RF energy from the surrounding environment, such as: 2G GSM, UMTS, 4G LTE, 5G NR, WIFI, etc. This energy is the energy radiated by other RF-equipped devices when working. (2) Exclusive energy, which is emitted by the card reader and its function is to provide a reliable energy source for the electronic tag, thereby obtaining relevant information of the electronic tag.

[0118] Optionally, in step S82, switching to the second electronic module to communicate with the card reader may include the following execution steps:

[0119] Step S823, obtaining the radio frequency energy emitted by the card reader;

[0120] Step S824: Convert radio frequency energy into a beacon signal by backscattering, and feed the beacon signal back to the card reader.

[0121] When backscattering is used to achieve significant energy reduction, there is no ultra-low power Bluetooth transceiver in the ultra-low power Bluetooth module. If there is no ultra-low power Bluetooth transceiver in the ultra-low power Bluetooth module, the collected RF energy is converted into a BLE beacon signal using the backscattering principle.

[0122] The backscattering principle is similar to that of a radar system, where the card reader transmits a continuous wave (CW) signal to the electronic tag. The electronic tag uses passive reflection to feed the signal back to the card reader, and modulates the signal by changing the resistance. Due to the lack of a transmitter, the required energy is significantly reduced, and only a small amount of electricity is required to maintain its encoding function. After repeated tests for many times, the results show that the energy required for this method will be less than 1 / 100 of that of traditional BLE. It should be noted that the implementation of this method requires a stable CW signal with a specific frequency. The source of the CW signal can be either a smart terminal or a dedicated device for transmitting CW signals.

[0123] Optionally, the above method may further include the following execution steps:

[0124] Step S83: Acquire the location information of the electronic tag using an ultra-wideband method.

[0125] In addition to the Bluetooth module, a third electronic module can be integrated into the electronic tag, such as Ultra-Wide Bandwidth (UWB). Electronic tags integrated with UWB can use UWB to accurately locate close-range objects (the electronic tag is set on the object), and use Bluetooth and Bluetooth ultra-low power modules to achieve fuzzy positioning of objects (for example, whether the object exists, the distance between the object and the card reader, but the exact location cannot be determined).
