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.

The electronic tag tracking system is a system for tracking and positioning tags by combining radio communication. Nowadays, a widely used electronic tag tracking system is the UHF RFID system [1 ]. An electronic tag tracking system generally includes an electronic tag reading terminal (hereinafter, referred to as a card reader) and an electronic tag to be tracked. The card reader is responsible for directly carrying out wireless communication with the electronic tag so as to acquire information of the electronic tag, such as the ID of the tag. The card reader can be independent, namely the card reader has independent operation and storage functions, and can calculate the position of the electronic tag by acquiring the information of the electronic tag, such as RSSI (received signal strength indicator) and store the information. The card reader can also be connected with the server so as to acquire the instruction to complete data transmission. Electronic tags typically contain a tag processing chip, a tag antenna. The structure of the electronic tag using different wireless transmission protocols may also be different. If the electronic tag adopting the passive RFID technology does not need a power supply, the electronic tag only consists of a tag chip and a tag antenna. Electronic tags adopting other wireless technologies also need original components such as a microprocessor, a power management chip and a power supply.

The electronic tag tracking system is mainly applied to article tracking. In this system, an electronic tag is placed on an item to be tracked, and a user performs item tracking by locating the electronic tag with a card reader. The electronic tag system can be applied to real-time positioning and tracking of goods in logistics. The system may also be applied to consumer-level applications (toC), such as to assist users in tracking and locating lost items.

Electronic label systems can be broadly divided into short range (<500m) and long range (>500m) depending on the architectural characteristics of the wireless communication technology. Short and long distance positioning has great difference in the requirements of wireless technology and the architecture of the system. The prior art can only be applied to one of the two scenarios.

Short-range location systems typically require a direct wireless data exchange between a card reader and an electronic tag. The card reader judges the position of the electronic tag by the acquired electronic tag information such as RSSI and combining a positioning algorithm. Within a certain range (e.g. a range of less than 500m) the reader (i.e. the first electronic device) may calculate the position of the first electronic tag. The advantage of this technique is simplicity. I.e. using mature BLE wireless communication technology, and the card reader is here the first terminal (or smart terminal), BLE technology is also widely fused in smart terminals. The system has the disadvantage that the user can only locate the electronic tag within a certain range, but the user cannot communicate with the electronic tag beyond the distance, so that the electronic tag cannot be tracked.

Long-range positioning usually utilizes a GNSS combined with a cellular network for long-range tracking. The electronic tag is internally provided with a GPS and 2G GSM processing chip. And the electronic tag sends the acquired GPS position information to the user terminal through a GSM network. The card reader (namely, the intelligent terminal) does not directly exchange data with the electronic tag, but acquires information through a 2G network. The technology has the advantages of long distance, and the electronic tag can be positioned under the conditions of GPS and GSM network coverage even if the electronic tag is far away from the card reader. The disadvantage of this technique is the use of scenes and delays. The GPS signal is greatly attenuated indoors, thereby reducing the accuracy of positioning. The technology applies two wireless technologies of GPS and GSM, and the communication modes of the technology need to pass through a more complex communication protocol, thereby causing time delay. In summary, this technique is not suitable for indoor, short-distance real-time article tracking systems.

In summary, no electronic labeling system has been available that combines short and long distance item tracking. The user needs to purchase different categories of electronic tags to target different application scenarios. Therefore, the tag can not be positioned more efficiently, and the electronic tag can not adapt to more scenes, so that the working capacity of the electronic tag can not be improved. The solution provided by this embodiment is mainly used to solve the above problems.

An embodiment of the present invention provides an electronic tag positioning method, as shown in fig. 2, including:

step 21: the first electronic equipment determines the relative position relation with the first electronic tag;

step 22: the first electronic equipment determines a triggered positioning function according to the relative position relation, and determines the position information of the first electronic tag according to the positioning function;

Correspondingly, in a process of interaction between the first electronic device and the electronic tag, the electronic tag needs to provide a corresponding signal to enable the first electronic device to perform positioning, and specifically, this embodiment further provides an electronic tag positioning method, as shown in fig. 3, including:

step 31: the first electronic tag provides position related information for the first electronic equipment according to the triggered positioning function; wherein the related information is used for determining the position information of the first electronic tag;

The first electronic device may be understood as a card reader, or may be understood as a terminal device mounted with a card reader. The first electronic tag is an electronic tag which can be detected by the first electronic equipment.

In the present embodiment, the wireless technologies are classified into two types, i.e., short-range communication and long-range communication. The short-distance communication refers to the fact that the distance between a node and the node or between a label and a card reader is smaller than a preset distance, and the communication distance is not smaller than the preset distance in long-distance communication. The preset distance may be 500m (meters), although longer or shorter distances may be provided, and are described here as an example only. In one example, the distance between the tag and the reader is less than 500 meters at short distances, and greater than 500 meters at long distances.

As shown in fig. 4, the technology (or communication module) corresponding to the long-distance communication or long-distance positioning function may include a Cellular communication module and/or a GNSS communication module.

The Cellular includes GSM (Global System for Mobile Communications), UMTS (Universal Mobile Telecommunications System), LTE (Long Term Evolution), 5G NR (New Radio), and other Cellular communication technologies.

GNSS (Global Navigation Satellite System) includes Satellite Positioning technologies such as Global Positioning System (GPS), GLONASS (GLONASS), BeiDou (BeiDou), Galileo (Galileo), and the like.

As shown in fig. 4, the technology (or communication module) corresponding to the short-distance positioning function may be at least one of an Ultra Wide Band (UWB) module, a Bluetooth Low Energy (BLE) module, a UHF (Ultra high frequency) RFID module, and a WIFI module. The communication distances of the communication modules corresponding to each short-range positioning function are shown in the figure, and are not described herein again.

In the above, WIFI is classified as short-distance communication from the point-to-point communication distance perspective, and from the practical application perspective, since the WIFI network is widely used, it is also classified as long-distance communication. Another understanding is that short-range communication means that the reader and the electronic tag can directly perform data transmission without any other wireless device or network structure. Long-range communication means that the reader and the electronic tag need to communicate wirelessly by means of other devices, such as a base station in a cell. Therefore, the WIFI technology can be used for direct data exchange between short distance points and points, and can also be used for long distance exchange by using a router. In the tracking system using the WIFI technology, only a single WIFI communication module is needed.

GNSS technology, such as GPS, is a one-way communication technology, i.e., a receiving module receives only signals from satellites and processes the signals through a GNSS chip. The GNSS chip cannot actively transmit the processed data. I.e. GNSS systems contain only receivers and no transmitters. Therefore, if GNSS technology is used in long-distance communication, another long-distance two-way communication technology assistance, such as Cellular or WIFI, is required.

The electronic tag tracking system provided by the embodiment includes a card reader (which can be understood as the aforementioned first electronic device), and a first electronic tag. The first electronic tag has the short-distance and long-distance communication module in T1, or the first electronic tag provided in this embodiment may only have the communication module corresponding to the short-distance positioning function. In addition, the card reader of the present embodiment, that is, the first electronic device, needs to have the short-distance positioning function and the communication module corresponding to the long-distance positioning function.

In this embodiment, the short-distance and/or long-distance communication modules of the first electronic device and the first electronic tag are at least one selected from the communication modules corresponding to the short distance in fig. 4, and at least one selected from the communication modules corresponding to the long distance.

For example, the first electronic device may be a card reader, where the card reader may be a standalone device with computing and storing functions, such as a smart terminal (smart phone, tablet). In this system, the card reader needs to be equipped with a short and long distance communication module like an electronic tag.

Generally, a smart terminal (such as a smart phone) is equipped with BLE, WIFI, cellular modules. There is also intelligent terminal to be equipped with UWB short distance module. Alternatively, the reader may be connected to the server, in which case. The card reader only needs to be provided with a short-distance communication module which is the same as the electronic tag. The operation, storage and long-distance data exchange of the data are all completed by the server.

Based on this, the scheme provided by the present embodiment is described in detail with reference to the following examples:

examples 1, 1,

With reference to fig. 5, the flow of the present example may include:

step 51, the first electronic device starts scanning.

In particular, the first electronic device (which may be understood as a card reader) initiates a scan for the first electronic label.

Still further, a setting may be first performed for a tag tracking function of the first electronic device (i.e., the card reader), the first electronic tag to be tracked is input, for example, the related information of the first electronic tag may be input, which may be at least one of an identification number, a serial number, and identification information of the first electronic tag, and then the first electronic device (i.e., the card reader) may prepare to start the tag scanning function.

And step 52, the first electronic device performs short-distance scanning on the first electronic tag to obtain a short-distance scanning result.

Namely, the card reader firstly starts the short-distance communication module to start scanning the first electronic tag. The step is aimed at judging the existence of the first electronic label in the communication range of the short-distance communication module.

Since the information related to the first electronic tag is already set in the first electronic device (card reader) in the foregoing step 51, the short-distance scanning of the first electronic tag may be performed according to the set information in this step.

In the course of executing this step, the first electronic device (card reader) may perform short-range scanning of the first electronic tag in a corresponding mode. Wherein, the corresponding mode may include but is not limited to at least one of the following: maximum transmit power is used, maximum power is required for electronic tag transmission via a communication protocol, multiple antenna scanning, instructing a user to change physical locations, etc.

That is, the user can set different modes, such as short range scanning using maximum transmit power; or, the set mode is to instruct the user to change the physical location, during the short-distance scanning, the first electronic device may provide the user with location change instruction information through the screen, for example, instruction information of walking right or turning left, so that the direction or location of the first electronic device is more suitable for performing the short-distance scanning to obtain the final short-distance scanning result.

Step 53, the first electronic device determines a relative position relationship between the first electronic device and the first electronic tag, and determines a triggered positioning function according to the relative position relationship; if it is determined that the short-range positioning function is triggered, step 54 is performed, and if it is determined that the long-range positioning function is triggered, step 55 is performed.

Specifically, the determining a relative position relationship with the first electronic tag includes:

if the short-distance scanning result is that the first electronic tag is scanned, determining that the relative position relation between the first electronic tag and the short-distance scanning result is a first position relation;

and if the short-distance scanning result indicates that the first electronic tag is not scanned, determining that the relative position relation between the first electronic tag and the short-distance scanning result is a second position relation.

Here, the first positional relationship may be understood as a positional relationship in which the first electronic device and the first electronic tag are in a close range, or a short-range positional relationship; the second positional relationship may be understood as a long-distance positional relationship or a long-distance positional relationship between the first electronic device and the first electronic tag.

The first electronic device determines a triggered positioning function according to the relative position relationship, and the method comprises the following steps:

if the relative position relationship is a first position relationship, determining to trigger a short-distance positioning function; and if the relative position relation is the second position relation, determining to trigger the long-distance positioning function.

The short-range positioning function has been described in the foregoing embodiments, and it can be considered that when the short-range positioning function is triggered, the corresponding short-range communication module is turned on, and the subsequent short-range positioning is performed through the corresponding short-range communication module; the long-distance positioning function is similar to the long-distance positioning function, and is not described in detail. The short-range communication module and the long-range communication module are described above and will not be described again.

Based on the above step 53, a positioning algorithm to be subsequently used can be determined, and the positioning algorithm is an important component of the tracking system. These positioning algorithms are either already in widespread use or in the experimental verification phase. The positioning method can be applied to the scheme provided by the embodiment. The following description will be made with reference to step 54 and step 55, respectively.

And step 54, the first electronic device starts the short-distance positioning function, presents the position of the first electronic tag, and ends the processing.

Here, in a case where the positioning function is a short-distance positioning function, the first electronic device determines the relative position information of the first electronic tag according to the detected positioning signal of the first electronic tag. That is, the position information of the first electronic tag finally obtained in this step may be the relative position information of the first electronic tag with respect to the first electronic device.

The first electronic device determines the relative position information of the first electronic tag according to the detected positioning signal of the first electronic tag, and the determining method comprises the following steps:

the first electronic equipment sends a second positioning instruction to the first electronic tag;

the first electronic equipment detects positioning information sent by the first electronic tag, determines the relative distance and the relative angle of the first electronic tag based on the positioning information, and takes the relative distance and the relative angle as the relative position information of the first electronic tag.

Correspondingly, the first electronic tag receives a second positioning instruction sent by the first electronic device, and determines that the triggered positioning function is a short-distance positioning function.

The step mainly adopts a short-distance positioning method. In the process of short-distance positioning, a card reader and an electronic tag are generally required to perform direct wireless data exchange. The card reader judges the position of the electronic tag by the acquired electronic tag information such as RSSI and combining a positioning algorithm. Within a certain range (e.g. a range of less than 500m) the reader (i.e. the first electronic device) may calculate the position of the first electronic tag.

Specifically, for different short-distance communication technologies, the positioning algorithm is similar, and mainly adopts RSSI (Received Signal Strength Indication), phase and time scale to calculate distance, and uses Angle of arrival (AOA) to calculate Angle.

For example, as in a Radio Frequency Identification (RFID) system, using RSSI and phase information of a tag antenna, a reader can calculate a distance r between a tag and the reader, which can be regarded as a relative distance between the reader, that is, a first electronic device and a first electronic tag; with Angle of arrival (AOA), the Angle θ of the tag to the reader can be calculated, and it can be considered that the relative Angle between the first electronic device and the first electronic tag is calculated by the AOA. It should be noted that, in this example, the finally obtained position information of the first electronic tag is the relative position information of the first electronic tag, which includes the relative distance and the relative angle.

The RSSI and the phase information are combined, a model can be established for the environment, or a signal processing method is adopted to improve the accuracy of distance operation.

For another example, the distance between the card reader and the electronic tag can be calculated by Time of Flight (ToF) positioning using UWB technology. And calculating the included angle between the electronic tag and the card reader by using an AOA (automated optical inspection) mode so as to obtain the relative position of the electronic tag and the card reader.

Of course, there may be more other types of short-distance positioning modules, and the positioning module may be positioned by using a corresponding positioning method, which is not exhaustive in this example.

And step 55, the first electronic device starts a long-distance positioning function and displays the position of the first electronic tag.

And in the case that the positioning function is a long-distance positioning function, the first electronic equipment takes the position coordinates of the first electronic tag acquired through the network equipment as position information.

The first electronic device uses the position coordinates of the first electronic tag acquired through the network device as position information, and the method includes:

the first electronic equipment sends a first positioning instruction to the first electronic tag through the network equipment;

and the first electronic equipment receives the position coordinates fed back by the first electronic tag through the network equipment.

Correspondingly, the first electronic tag receives a first positioning instruction of the first electronic device forwarded by the network device, and determines that the triggered positioning function is a long-distance positioning function.

In a case where the triggered positioning function is a long-distance positioning function, providing, by a network device, the position coordinates of the first electronic tag for the first electronic device includes:

in the case that the triggered positioning function is a long-distance positioning function, the first electronic tag determines position coordinates based on distances between the first electronic tag and the N network devices; n is an integer greater than or equal to 2; and providing the position coordinates of the first electronic tag for the first electronic device through network equipment.

In this step, triggering the long-distance positioning function may be understood as turning on the corresponding long-distance communication module, and the foregoing embodiments have been described with respect to the description of the long-distance communication module, and are not described again.

The network device can be a satellite or a base station; n may be 3 or 4, and of course may be more, or 2, as determined by the positioning algorithm.

Further, a positioning algorithm corresponding to the long-range positioning is described below, such as GNSS, which mainly determines the distance between the receiver (i.e. the first electronic tag) and the satellite by using a Time of Flight (ToF) method. The position coordinates (namely longitude coordinates and latitude coordinates) of the electronic tag are accurately positioned through the distance between the electronic tag and 4 satellites.

For another example, the method of positioning in cellular mode mainly uses the RSSI strength of the electronic tag received by the base station to determine the distance between the electronic tag and the base station, and since the position of the base station is known, the position of the electronic tag is calculated and positioned according to the distance between the base station and the base stations.

In combination with the above steps, the first electronic device may have two results after completing the scanning: the first electronic label is scanned, and 2 the first electronic label is not scanned. And if the first electronic tag is scanned, the card reader starts the short-distance positioning function of the first electronic tag and presents the result to the user. If the label is not scanned, the card reader starts the long-distance module so as to acquire label position information and present the information to a user.

Examples 2,

The difference from example 1 is that the first electronic device in this example receives the position coordinates of the first electronic tag, and then determines the relative position relationship and subsequent processing according to the position coordinates of the first electronic tag.

The receiving of the position coordinate of the first electronic tag may be that the first electronic device receives the position coordinate of the first electronic tag sent by the network device. The network device may be a base station (eNB, gNB, etc.) in a terrestrial communication network or a satellite in a satellite communication network, and of course, the network device is not exhaustive as long as the device capable of forwarding information is within the protection range in this example.

Specifically, the determining the relative position relationship with the first electronic tag comprises:

determining the relative distance between the first electronic equipment and the first electronic tag according to the position coordinate of the first electronic tag;

if the distance between the first electronic device and the first electronic tag is not greater than the distance threshold value, determining that the relative position relationship between the first electronic device and the first electronic tag is a first position relationship; and if the distance between the first electronic equipment and the first electronic tag is greater than the distance threshold value, determining that the relative position relationship between the first electronic equipment and the first electronic tag is a second position relationship.

and if the relative position relation is the first position relation, determining to trigger the short-distance positioning function.

That is to say, whether the distance between the first electronic tag and the first electronic device is smaller than a preset distance threshold value is determined according to the position coordinate of the first electronic tag and the position coordinate of the first electronic device, if the distance between the first electronic tag and the first electronic device is smaller than the preset distance threshold value, the short-distance positioning function can be started or triggered, then the short-distance positioning is carried out through the short-distance communication module, and finally the relative position relationship between the first electronic tag and the first electronic device is obtained.

Here, the processing regarding short-distance positioning between the first electronic tag and the first electronic device is the same as that described in step 54 of the foregoing example 1, and is not described again.

In addition, the method provided by this example further includes: and if the relative position relationship is a second position relationship, taking the position coordinate of the first electronic tag as the position information of the first electronic tag.

That is to say, whether the distance between the first electronic device and the first electronic tag is smaller than a preset distance threshold value is determined according to the position coordinate of the first electronic tag and the position coordinate of the first electronic device, if so, the distance between the first electronic device and the first electronic device is considered to be longer, short-distance positioning can be avoided, and the received position coordinate is directly used as the position information of the first electronic tag.

In one example, the first electronic tag includes a GNSS and a cellular module, and the first electronic tag transmits the position information to the terminal through a cellular network without sending an instruction from a card reader (first electronic device). Under the condition, the card reader can judge whether to open the close-range module according to the acquired label position. If the positions of the tag and the card reader are larger than a distance threshold value (which can be 2Km, or can be 1Km, or can also be 500m, and is set according to actual conditions), the short-distance communication module does not need to be started, and the long-distance information is directly presented to the user.

The processing method for determining whether to directly acquire the position coordinate by the first electronic tag without receiving the second positioning instruction and the first positioning instruction sent by the first electronic device may include:

the first electronic tag and the first electronic equipment perform periodic scanning inquiry, and record the scanning inquiry result; if the number of times of failure of the scanning inquiry continuously exceeds a preset threshold value, the first electronic tag determines a position coordinate based on the distance between the first electronic tag and the N network devices; n is an integer of 2 or more. The preset threshold may be 3 times or more. The periodicity may be understood as a time interval (may be referred to as T1), and the length of one period is set according to actual requirements.

The method further comprises the following steps: and the first electronic tag sends the position coordinates to the first electronic equipment through network equipment.

That is, the first electronic tag may be in a sleep state at ordinary times, and only maintain the awakened function. The first electronic device performs scanning interrogation to the electronic tag at certain time intervals T1 (or understood as periodic (the period length is T1)), and wakes up the first electronic tag.

Then, the first electronic tag can perform periodic scanning inquiry to the first electronic device, and record the result of each scanning inquiry; and if the scanning inquiry result shows that the failure times are greater than a preset threshold value, the first electronic tag carries out long-distance positioning.

Or after the first electronic tag is awakened, the first electronic device periodically performs scanning inquiry to the first electronic tag, the first electronic tag records an inquiry result, and if the number of times of failure of the scanning inquiry result is greater than a preset threshold value, the first electronic tag performs long-distance positioning.

The process in which the inquiry is scanned may be understood as: the first electronic tag sends an inquiry message, if the reply is received, the scanning inquiry result is successful, otherwise, the scanning inquiry result is failed.

The processing for performing long-distance positioning is the same as that of the foregoing example 1, and is not described here again.

Examples 3,

The difference from example 1 is that, in this example, the first electronic tag may only include the short-distance positioning function, that is, the short-distance positioning module, but does not include the long-distance positioning function (that is, the long-distance positioning module).

Then, in connection with example 1, when step 55 is executed, a processing manner different from that of example 1 may be adopted, which specifically includes:

the first electronic equipment initiates a sharing request to network equipment; wherein the sharing request comprises related information of the first electronic tag;

the first electronic equipment receives the position related information of the first electronic tag, which is fed back by the network equipment and detected by the second equipment; the position related information of the first electronic tag comprises: the position coordinates of the second equipment and the relative position information between the first electronic tag and the second equipment;

and determining the position coordinates of the first electronic tag based on the position related information of the first electronic tag.

That is to say, the first electronic device sends a sharing request to the other device through the terrestrial communication network or the satellite communication network, where the sharing request may include related information of the first electronic tag, for example, identification information or a number of the first electronic tag.

After other devices (second devices) receive the sharing request, the short-distance positioning function can be started according to the related information of the first electronic tag, namely, the short-distance communication module carries out short-distance scanning on the first electronic tag, if the short-distance communication module scans the first electronic tag, short-distance positioning can be further executed, and then the second devices send the position coordinates of the second devices and the relative position of the first electronic tag which is positioned by the second devices to the first electronic device through a ground communication network or a satellite communication network.

Then, the first electronic device may determine the position coordinates of the first electronic tag according to the position coordinates of the second device and the relative position relationship between the second device and the first electronic tag.

With reference to this example, the first electronic device may further receive a sharing request for the second electronic tag sent by another device (for example, a third device), and then the first electronic device may perform short-distance scanning on the second electronic tag, and if the first electronic device does not scan the second electronic tag, the first electronic device does not perform processing; if so, a short range location fix may be made, step 54 of example 1, and the first electronic device then transmits its location coordinates and its relative location with the second electronic tag to the other device (e.g., a third device) via a terrestrial communication network or a satellite communication network.

Specifically, in this example, the electronic tag includes only a short-range communication system. Such as UWB. Then when the reading range of the electronic tag exceeds the reading distance between the electronic tag and a card reader (intelligent terminal). The intelligent terminal user can share the tracking label information by using a network. The intelligent terminal of any user has the UWB function, and can start the electronic tag searching function after receiving the sharing information. And if the electronic tag is found, sending the GNSS positioning of the intelligent terminal and the positioning information of the intelligent terminal to the UWB electronic tag to the world wide web and finally sending the information to the intelligent terminal of the tag finding initiator. The scheme can be realized by developing a mobile phone intelligent terminal APP.

In conjunction with the foregoing example, example 4, the first electronic tag may include UWB and GNSS/Cellular.

Fig. 6 shows a first electronic tag of the present example, which includes a radio frequency module UWB (short-range communication module), GNSS, Cellular, and a corresponding antenna (long-range communication module). Microprocessor, power management chip and battery.

The GNSS is a satellite positioning system supporting one or more of GPS, GLONASS, BeiDou and Galileo. Celluar is a cellular communication technology supporting one or more of GSM, UMTS, LTE,5G NR. The corresponding terminal device (or first electronic device) of this system is shown in fig. 7.

The UWB antenna is integrated into the smart terminal back cover. UWB processing chip is integrated to intelligent terminal inner circuit board.

The radio frequency module comprises UWB, GNSS and Cellular. UWB is the short distance module wherein, GNSS, and Cellular is the long distance module. All three modules require power.

In one example, to increase battery life and reduce power consumption, the operation of the three modules when the reader is not actively scanning may be followed as follows. These three kinds of modules all are in the deep sleep state, and UWB promptly, Cellular module transmitter do not all emit the signal, and the GNSS module received the signal but do not carry out signal processing.

This example, in conjunction with example 2, the deep sleep of UWB only maintains the awakened function. The reader scans and interrogates the electronic tag at certain time intervals T1, waking up the UWB. The UWB module transmits a signal, and the signal only contains the independent identification code of the electronic tag. The card reader transmits the inquiry information to the electronic tag after receiving the inquiry information. The success or failure of each inquiry (e.g. whether a reply to the inquiry is received, if so, the inquiry is successful, otherwise, the inquiry is failed) is recorded by the electronic tag microprocessor. When n T1 intervals (n may be set according to actual conditions, and n may be greater than or equal to 2) are continuously performed, the result of the electronic tag inquiry is a failure, and the microprocessor controls the GNSS and the Cellular module to be in the active mode at the same time. The GNSS module receives the signals and transmits the calculated position to the microprocessor. The microprocessor transmits this information to the Cellular network via the Cellular module and ultimately to the card reader.

Example 5, another first electronic tag includes a structure including UHF RFID, GNSS, and/or Cellular.

Fig. 8 is a schematic structural diagram of the tag. The difference from example 4 is that the UWB module in example 4 is replaced with an RFID module in this example.

The RFID module comprises a UHF RFID antenna and an RFID tag chip. The UHF RFID module is passive, namely does not need a battery to supply power, and the power is supplied to the chip by capturing the energy transmitted by the card reader. The GNSS and Cellular modules still require power, so a power management chip and a battery are arranged inside the electronic tag. Short, long range positioning handover has been described in example 1 and will not be described again. The scheme related to RFID location is shown in the previous example and will not be described again.

The scheme provided by the embodiment provides an electronic tag tracking system or positioning system combining short distance and long distance, and multiple scenes of one tag can be realized. The user can realize short-distance, long-distance, indoor and outdoor multi-scene application only by one electronic tag.

Therefore, by adopting the scheme of the embodiment, the positioning function to be triggered can be determined according to the relative position relationship between the first electronic device and the first electronic tag, and then short-distance positioning or long-distance positioning can be performed, and finally the position information of the first electronic tag is obtained. So, realized that nearly remote electronic tags who combines together tracks, only need an electronic tags alright realize closely remote location, the more efficient carries out the label location to make electronic tags's positioning scheme can adapt to more scenes, promote electronic tags's working ability.

An embodiment of the present invention provides an electronic device, as shown in fig. 9, including:

a first processing unit 61 that determines a relative positional relationship with the first electronic tag; determining a triggered positioning function according to the relative position relation, and determining the position information of the first electronic tag according to the positioning function;

the electronic device further includes:

and/or the presence of a gas in the gas,

In particular, the first electronic device (which may be understood as a card reader) initiates a scan of the first short-range communication unit 62 for the first electronic tag.

Still further, the first processing unit 61 of the first electronic device may first perform setting for the tag tracking function, input the first electronic tag to be tracked, for example, input related information of the first electronic tag, which may be at least one of an identification number, a serial number, and identification information of the first electronic tag, and then the first electronic device (i.e., the card reader) may prepare to start the tag scanning function.

The first short-distance communication unit 62 of the first electronic device performs short-distance scanning on the first electronic tag to obtain a short-distance scanning result.

The first processing unit 61 of the first electronic device determines a relative position relationship with the first electronic tag, and determines the triggered positioning function according to the relative position relationship.

Specifically, if the short-distance scanning result is that the first electronic tag is scanned, the first processing unit 61 of the first electronic device determines that the relative position relationship with the first electronic tag is a first position relationship;

The first processing unit 61 of the first electronic device determines to trigger the short-distance positioning function if the relative position relationship is the first position relationship; and if the relative position relation is the second position relation, determining to trigger the long-distance positioning function.

Examples 2,

The difference from example 1 is that the first long-distance communication unit 63 of the first electronic device of this example receives the position coordinates of the first electronic tag, and then determines the relative positional relationship and subsequent processing from the position coordinates of the first electronic tag.

Specifically, the first processing unit 61 of the first electronic device determines a relative distance between the first electronic device and the first electronic tag according to the position coordinates of the first electronic tag; if the distance between the first electronic device and the first electronic tag is not greater than the distance threshold value, determining that the relative position relationship between the first electronic device and the first electronic tag is a first position relationship; and if the distance between the first electronic equipment and the first electronic tag is greater than the distance threshold value, determining that the relative position relationship between the first electronic equipment and the first electronic tag is a second position relationship.
