Detailed Description

In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

At present, the electronic tags applied to article tracking have a technical problem to be solved urgently: the length of use is long. The lifetime of an electronic tag is mainly limited by the battery capacity inside the electronic tag. If the battery capacity is exhausted, the electronic tag cannot communicate with the card reader, and therefore, the article tracking function cannot be realized.

Passive rfid (passive rfid) is an electronic tag that does not require a power source. The electronic tag converts radio frequency energy emitted by a card reader into internal power supply. Therefore, such an electronic tag is generally composed of a tag antenna and a tag chip, and a built-in battery is not required. Theoretically, as long as the electronic tag is not damaged in a physical layer, the electronic tag can be permanently used. However, the card reader necessary in the RFID system provided in the related art still belongs to a special device, which lacks the wireless transmission protocol such as bluetooth, wireless fidelity (WIFI) and the like widely used in consumer electronic terminals (e.g., smart phones, tablets). In addition, RFID readers are bulky, expensive, and thus difficult to adapt for consumer-level applications. That is, the desire for consumers to carry a special device with them that is bulky and expensive to use specifically for electronic tag tracking is clearly of no practical significance. Therefore, RFID systems are mainly suitable for enterprise-level application scenarios, such as: article tracking in the field of logistics.

One type of consumer-grade electronic tags that are currently in widespread use on the market has a maximum service life of 3 years and replaceable batteries. However, the remaining capacity of the battery cannot be sufficiently determined during the use of the electronic tag. If the battery of the electronic tag is not replaced in time after the electronic tag is used for a period of time, and articles are stolen under the condition, the tracking function of the electronic tag is possibly lost due to the fact that the electric quantity of the battery is quickly exhausted. Although the electronic tag manufacturer can set the battery replacement prompt, it is still difficult to ensure that the user can replace the battery on time, and it is impossible to ensure the long-term tracking efficacy after the article is stolen.

As for another type of consumer-level electronic tags provided in the current market, a Bluetooth Low Energy (BLE) technology is mainly used, and the BLE technology is an application of Low power consumption in the Bluetooth technology, and compared with the conventional Bluetooth technology, the BLE can reduce the power consumption of a chip by adopting different channels and coding and decoding modes. However, the service life of the electronic tag is limited to 2-3 years, which is far shorter than that of the Passive RFID electronic tag. And the purpose of applying BLE technology is: the method is suitable for consumer electronic terminals which commonly use BLE.

Therefore, the most obvious way to improve the service life of the electronic tag is as follows: however, since the battery capacity is proportional to the volume of the electronic tag, the use of a large-capacity battery inevitably increases the volume of the electronic tag, thereby affecting the practicability and the aesthetic property of the product.

In addition, although the power consumption can be reduced by prolonging the signal transmission period of the electronic tag and reducing the signal transmission frequency, and further the service life is prolonged (for example, the power consumption can be reduced by half theoretically by the electronic tag which sends a signal every 20 seconds than the electronic tag which sends a signal every 10 seconds), the reduction of the signal transmission frequency reduces the probability that the electronic tag is discovered, thereby seriously affecting the user experience.

In summary, there is a lack in the related art of an electronic tag that can be applied to the consumer market and can be used for a long time.

The technical scheme of the embodiment of the invention can be applied to various communication systems, such as: a Global System for Mobile communications (GSM) System, a Code Division Multiple Access (CDMA) System, a Wideband Code Division Multiple Access (WCDMA) System, a General Packet Radio Service (GPRS), a Long Term Evolution (Long Term Evolution, LTE) System, a Frequency Division Duplex (FDD) System, a Time Division Duplex (TDD), a Universal Mobile Telecommunications System (UMTS), a Worldwide Interoperability for Microwave Access (WiMAX) communication System, or a 5G System.

For example, a communication system applied in the embodiment of the present invention may include an electronic tag, where the electronic tag may be a device that communicates with a terminal device (or referred to as a communication terminal or a terminal). The electronic tags may provide communication coverage for a particular geographic area and may communicate with terminal devices located within that coverage area.

The communication system further comprises at least one terminal device located within the coverage area of the electronic label. "terminal equipment" as used herein includes, but is not limited to, connections via wire lines, such as connections via the Public Switched Telephone Network (PSTN), Digital Subscriber Line (DSL), Digital cable, direct cable; 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 means of another terminal device arranged to receive/transmit communication signals; and/or Internet of Things (Internet of Things, IoT for short) devices. A terminal device arranged to communicate over 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 Systems (PCS) terminals that may combine cellular radiotelephones with data processing, facsimile, 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 a radiotelephone transceiver. Terminal Equipment may refer to an access terminal, User Equipment (UE), subscriber unit, subscriber station, mobile, remote station, remote terminal, mobile device, User terminal, wireless communication device, User agent, or User Equipment. An access terminal may 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 capability, 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 PLMN for future evolution, etc.

Optionally, D2D communication may be performed between the terminal devices.

Alternatively, the 5G system or the 5G network may also be referred to as an NR system or an NR network.

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

It should be understood that a device having a communication function in a network/system in the embodiment of the present invention may be referred to as a communication device. The communication device may include an electronic tag and a terminal device having a communication function, and the electronic tag and the terminal device may be the above-mentioned specific devices, which are not described herein again; the communication device may further include other devices in the communication system, such as other network entities like a network controller, a mobility management entity, and the like, which is not limited in the embodiment of the present invention.

It should be understood that the terms "system" and "network" are often used interchangeably herein. The term "and/or" herein is merely an association describing an associated object, meaning that three relationships may exist, e.g., a and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.

According to one embodiment of the invention, an electronic tag is provided. Fig. 1 is a block diagram of an electronic tag according to an embodiment of the present invention, and as shown in fig. 1, the electronic tag includes: radio frequency subassembly and power supply unit spare, the radio frequency subassembly includes: the power consumption of the second electronic module is smaller than that of the first electronic module. The power supply assembly is used for supplying power to the electronic tag; the first electronic module is used for communicating with the card reader when the residual electric quantity of the power supply assembly is greater than or equal to an electric quantity threshold value; and the second electronic module is used for communicating with the card reader when the residual electric quantity is smaller than the electric quantity threshold value. Therefore, 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 scenes.

In an alternative embodiment, the first electronic module and the second electronic module may adopt an independent chip structure or an integrated chip structure.

In an alternative embodiment, the power supply assembly may be a battery. The first electronic module may be a classic bluetooth module. The second electronic module can be an ultra-low power consumption 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 In Package (SiP). The advantage of such integration is that ultra low power bluetooth transceivers can be reused. In addition, the Bluetooth module and the ultra-low power consumption Bluetooth module can also be respectively positioned on mutually independent chips.

Bluetooth 4.0 and its newer versions of bluetooth technology include not only classic bluetooth functionality but also BLE functionality. The classic bluetooth function may be used for traditional data transmission, and the BLE function may employ beacons (beacons) to transmit signals without actively connecting with the reader, so that the reader discovers the electronic tag. The power consumption of the classic bluetooth function is about 1W, while the power consumption of the BLE function is 10-500 mW. Classic bluetooth functionality 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. While BLE functionality may be understood as a one-way communication technique. The beacon signal emitted by the electronic tag usually contains the preload information specified by the BLE standard and the tag specific identification code. Fig. 2 is a schematic diagram of communication interaction between a bluetooth electronic tag and a card reader according to an alternative embodiment of the present invention, as shown in fig. 2, the electronic tag is in BLE mode in most cases, that is, the electronic tag intermittently transmits beacon. The card reader (for example: intelligent terminal) catches the beacon signal and decodes the beacon signal, and then transmits a control instruction through the classic bluetooth technology, for example: and controlling the electronic tag to ring or vibrate so as to locate the electronic tag.

Bluetooth ultra low energy modules are another bluetooth technology that is distinguished from BLE. The power consumption of BLE is 10-500mW, and the power consumption of the ultra-low power consumption Bluetooth module is less than 100 uW. Under the same electric quantity, the expected use time of the electronic tag system is 100 times longer than that of the Bluetooth module. The bluetooth module is a module supporting bluetooth 4.0 and its updated version and including a bluetooth transceiver.

In an alternative embodiment, the first electronic module and the second electronic module may share the same antenna, or may use the first antenna and the second antenna that are independent of each other. The first antenna and the second antenna are switched by the antenna switcher. The same antenna can be a broadband antenna or a common antenna.

An RF energy capture storage device is required in the bluetooth ultra-low energy module, and is used for capturing RF signals with the same frequency spectrum as bluetooth (i.e. 2.4-2.5GHz), for example: and (5) WIFI signals. Thus, the RF energy capture storage device may share the same antenna as the ultra-low power bluetooth transceiver. The RF energy capture storage device may 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 capture RF energy of different frequencies simultaneously using an antenna corresponding to the spectrum of energy to be captured or using a multi-antenna, broadband antenna.

Optionally, the electronic tag may further include: an inductive component; the sensing assembly is used for acquiring the residual electric quantity; the first electronic module is used for communicating with the card reader when the residual electric quantity is greater than or equal to the electric quantity threshold value; and when the residual electric quantity is smaller than the electric quantity threshold value, the second electronic module communicates with the card reader.

The first sensing component may be a power acquisition sensor. Fig. 3 is a schematic structural diagram of a dual-system electronic tag combining high power consumption and low power consumption according to an alternative embodiment of the present invention, as shown in fig. 3, the electronic tag system includes: the antenna, the antenna switch, the bluetooth module, ultra-low power consumption bluetooth module, microprocessor, power manager, sensor and battery are acquireed to the electric quantity.

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

The first processing component may be a microprocessor. In an alternative embodiment, the plurality of devices inside the electronic label may be distributed on separate chips. For example: the microprocessor, power manager and power acquisition sensor may be distributed on separate chips. In an alternative embodiment, multiple devices inside the electronic label may be integrated into one chip or SiP. For example: the microprocessor, the power manager and the electric quantity acquisition sensor can be integrated in the Bluetooth module.

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

The second processing component may be a microprocessor. In an alternative embodiment, the plurality of devices inside the electronic label may be distributed on separate chips. For example: the microprocessor, power manager and power acquisition sensor may be distributed on separate chips. In an alternative embodiment, multiple devices inside the electronic label may be integrated into one chip or SiP. For example: the microprocessor, power manager and power acquisition sensor may be integrated in an ultra low power bluetooth module.

Optionally, the second electronic module includes: an energy capture storage device; an energy capture storage device for harvesting radio frequency energy; when the radio frequency energy meets the transmission condition of the beacon signal, the beacon signal is transmitted by releasing the radio frequency energy, or the radio frequency energy is converted into the beacon signal by adopting a backscattering mode.

Optionally, the second electronic module may further include: a third processing component and a transceiver; the energy capture and storage device is also used for releasing the radio frequency energy to the transceiver when the radio frequency energy meets the transmission condition of the beacon signal; a transceiver for transmitting a beacon signal; a third processing component for controlling the transceiver to transmit a beacon signal based on the radio frequency energy.

Similar to BLE, the ultra-low power bluetooth module transmits beacon signals, wherein the beacon signals include preload information and tag-specific identification codes necessary for BLE standard specification. The beacon signal is encoded in the same way as BLE, so any device supporting bluetooth 4.0 and above versions can detect the beacon signal. In addition, different from BLE, the power consumption of the ultra-low power consumption Bluetooth module is less than one percent of the power consumption of BLE. The energy absorption and the backscattering are mainly adopted to realize the large-amplitude energy reduction. The biggest difference between these two approaches is: whether a BLE transceiver is present.

In an alternative 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. Fig. 4 is a schematic structural diagram of an ultra-low power bluetooth module according to an alternative embodiment of the present invention, as shown in fig. 4, the ultra-low power bluetooth module includes: RF capture storage, capacitors or batteries, ultra low power bluetooth transceivers, and microprocessors. The RF energy in the ambient environment is first harvested by an RF capture storage device and stored to an energy carrier (e.g., capacitor, rechargeable battery). When energy is stored to the extent that a BLE beacon signal can be transmitted, the stored energy is released to the ultra low power bluetooth transceiver. The ultra-low power consumption Bluetooth transceiver transmits beacon signals.

The method for realizing the ultra-low power consumption Bluetooth module by the RF energy acquisition mode theoretically does not need an external power supply. Therefore, when the ultra-low power consumption Bluetooth module is switched, the electronic tag can continuously work. In addition, certain power can be provided for the ultra-low power consumption bluetooth module (namely, a separate battery is newly added in the ultra-low power consumption bluetooth module) so as to wake up the chip or meet the ultra-low power consumption calculation requirement.

Optionally, the energy capture storage device may include: the antenna is connected with the first end of the rectifier, the second end of the rectifier is connected with the first end of the boost converter, and the second end of the boost converter is connected with the energy storage.

If the energy absorption mode is adopted to realize large-amplitude energy reduction, the ultra-low Power consumption Bluetooth module consists of a Bluetooth transceiver and an energy Harvesting (Power Harvesting) storage device. Fig. 5 is a schematic diagram of an energy capture storage device according to an alternative embodiment of the invention, and as shown in fig. 5, the energy capture storage device may include: an antenna, a rectifier, a boost converter, and an energy storage. The energy capture storage device can efficiently store less than-25 dBm of energy.

Optionally, the source of rf energy comprises at least one of: radio frequency energy in the environment surrounding the electronic tag; radio frequency energy emitted by the reader.

Sources of RF energy may generally include, but are not limited to: (1) energy reuse, i.e. harvesting RF energy in the surrounding environment, for example: 2G GSM, UMTS, 4G LTE, 5G NR, WIFI, etc. This energy is the energy radiated by other RF equipped devices when in operation. (2) Exclusive energy, this energy is launched by the card reader, and its effect lies in: and a reliable energy source is provided for the electronic tag, so that the related information of the electronic tag is acquired.

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

In an alternative embodiment, the fourth processing component may be a microprocessor and the energy capture storage device may be an RF energy capture storage device. When the backscattering mode is adopted to realize large-amplitude energy reduction, the ultra-low power consumption Bluetooth transceiver does not exist in the ultra-low power consumption Bluetooth module. Fig. 6 is a schematic diagram of a backscattering principle according to an alternative embodiment of the present invention, as shown in fig. 6, an ultra-low power consumption bluetooth transceiver is not disposed in the ultra-low power consumption bluetooth module, but the acquired RF energy is converted into a BLE beacon signal by using the backscattering principle.

The backscattering principle is similar to that of a radar system, and a card reader transmits a Continuous Wave (CW) signal to an electronic tag. The electronic tag feeds back a signal to the card reader in a passive reflection mode and modulates the signal by changing a resistance mode. Due to the lack of transmitters, the required energy is significantly reduced, requiring only a small amount of power to maintain its encoding function. The results of repeated experiments indicate that the energy required for this method is less than 1/100 for conventional BLE. It is noted that implementation of this approach requires a stable CW signal with a specific frequency. The source of the CW signal can be an intelligent terminal or a special device for transmitting the CW signal.

Optionally, the radio frequency assembly may further include: a third electronic module; and the third electronic module is used for acquiring the position information of the electronic tag.

In an alternative embodiment, within the electronic tag, a third electronic module can be integrated in addition to the bluetooth module, for example: ultra-wideband (UWB) for short.
