The first tag mode (Dongle mode) and the second tag mode (Client mode) are two operation modes of the target ultra-wideband tag. The power consumption of the target ultra-wide band tag in the first tag mode is smaller than that in the second tag mode; the target ultra-wide band tag can send the ranging data to the ultra-wide band matching equipment through the ultra-wide band communication link in the second tag mode so as to indicate the ultra-wide band matching equipment to calculate the target distance between the target ultra-wide band tag and the target ultra-wide band tag. The ranging data is data for measuring a distance. The ranging data may include distance information, and may also include distance information and angle information. Wherein the angle information may be at least one of angle information in a horizontal direction and angle information in a vertical direction.

The ultra-wide band matching equipment and the target ultra-wide band tag are matched ultra-wide band equipment and work cooperatively. The working mode of the ultra-wide band matching equipment is a first matching mode, and the working mode of the target ultra-wide band tag is a first tag mode. The target ultra-wide band tag only sends angle information in the horizontal direction to ultra-wide band matched equipment in a first tag mode; under the first matching mode, the ultra-wideband matching equipment only receives angle information in the horizontal direction sent by the target ultra-wideband tag, and then the ultra-wideband matching equipment can calculate the angle in the horizontal direction between the ultra-wideband matching equipment and the target ultra-wideband tag according to an ultra-wideband protocol. The working mode of the ultra-wide band matching equipment is a second matching mode, and the working mode of the target ultra-wide band tag is a second tag mode. The target ultra-wideband tag sends ranging data to ultra-wideband corollary equipment in a second tag mode; and the ultra-wideband corollary equipment receives ranging data sent by the target ultra-wideband tape tag in a second matching mode, and the ultra-wideband corollary equipment can calculate the target distance between the ultra-wideband corollary equipment and the target ultra-wideband tape tag according to an ultra-wideband protocol.

And under the condition that the working mode of the ultra-wideband matching equipment is the second matching mode and the working mode of the target ultra-wideband tag is the second tag mode, the electronic equipment and the target ultra-wideband tag communicate through a pre-established wireless communication link.

The electronic equipment responds to the ranging instruction, establishes a wireless communication link with the target ultra-wide band tag, and sends a mode switching instruction to the target ultra-wide band tag through the wireless communication link so as to instruct the target ultra-wide band tag to switch the working mode from the first tag mode to the second tag mode based on the mode switching instruction.

The user can press a designated physical key in the target ultra-wide band tag to broadcast the broadcast signal of the target ultra-wide band tag. Wherein the broadcast signal may be a bluetooth broadcast signal.

Optionally, under the condition that the working mode of the ultra-wideband matching device is the second matching mode and the working mode of the target ultra-wideband tag is the second tag mode, the ultra-wideband matching device and the target ultra-wideband tag receive and transmit data one to one, so that interference of other devices can be avoided.

In response to the ranging command, in this embodiment, the mode switch command is sent to the ultra-wideband companion device and the target ultra-wideband tag over the wireless communication link, to instruct the ultra-wideband companion device to switch from a first companion mode with lower power consumption to a second companion mode, to indicate that the target ultra-wide band tag is switched from a first tag mode that consumes less power to a second tag mode, the ultra-wideband matching equipment acquires the ranging data sent by the target ultra-wideband tag in the second tag mode through the ultra-wideband communication link in the second matching mode, the distance between the ultra-wideband matching equipment and the target ultra-wideband tag can be measured with higher precision, the accuracy of the ultra-wideband matching equipment and the target ultra-wideband tag identification equipment is improved, and therefore the relation between the power consumption and the accuracy of the ultra-wideband equipment (the ultra-wideband matching equipment and the target ultra-wideband tag) is balanced.

The working mode control method can also ensure that when the distance measurement is not needed, the ultra-wideband matching equipment works in the first matching mode with low power consumption, the target ultra-wideband tag works in the first tag mode with low power consumption, and the ultra-wideband tag is switched to the distance measurement mode only when the distance measurement is needed, so that the working mode is switched in a targeted manner; the power consumption of the ultra-wideband equipment is considered, and the realization of the ranging function is also ensured; the electronic equipment indicates the ultra-wideband matching equipment and the target ultra-wideband tape label to switch modes through the mode switching instruction, and therefore non-sensing switching of working modes can be achieved.

In one embodiment, the ultra-wideband companion device is an article having an ultra-wideband module that is affixed to the electronic device when the article is in use. The description will be given by taking an example in which the mobile phone terminal recognizes the ultra-wide band tag. When the electronic equipment is a mobile phone terminal and the ultra-wideband matching equipment is a UWB mobile phone shell, the UWB mobile phone shell can be worn on the mobile phone terminal. The ultra-wide band tag can be hung outside or attached to a controlled device (namely, an IOT intelligent device). IOT is the Internet of Things (IOT for short). The angle formed by the mobile phone terminal pointing to the smart home is the angle of the UWB mobile phone shell pointing to the UWB TAG device (UWB TAG device). Because the mobile phone terminal does not have the ability of measuring the angle, the ability comes from the mobile phone shell worn on the mobile phone, and the mobile phone wearing the UWB mobile phone shell points to the controlled equipment attached with the UWB label from the using mode of the user. The angle is determined by the UWB protocol, namely under the condition that the UWB mobile phone shell is perpendicular to the horizontal direction, the UWB mobile phone shell takes the direction pointed by the front of the UWB mobile phone shell as the angle 0, determines a connection line between the UWB mobile phone shell and the UWB TAG equipment, and determines the included angle between the UWB TAG equipment and the forward direction of the UWB mobile phone shell as the acquired angle information. Through this angle information, the mobile phone terminal can judge directive property between UWB cell-phone shell positive direction and UWB equipment. The identification between the UWB handset housing and the UWB TAG device is made according to UWB protocols. Information such as angle and distance is defined by the UWB protocol, and ID information, i.e., identification information, is device identification code information carried when the UWB protocol transfers information.

The mode that can adopt the bluetooth to be connected between cell-phone terminal and the UWB cell-phone shell, UWB cell-phone shell reports UWB data through BLE and gives cell-phone terminal, UWB cell-phone shell bluetooth reports data format as shown in figure 2: 2Byte (TYPE:0x6F70) +2Byte (VALUE _ Length) + UWB data variable Length (VALUE) +2Byte (CRC). Wherein, the VALUE _ Length includes the total Length of the VALUE and CRC result, i.e. size of (VALUE + CRC), and the VALUE includes 2Byte (REAL _ VALUE _ TYPE) +2Byte (REAL _ VALUE _ Length) + variable Length (REAL _ VALUE …). The meaning of the UWB data reported by the UWB mobile phone shell is shown in the following table 1:

TABLE 1

In addition, when the UWB mobile phone shell reports the UWB data to the mobile phone terminal through BLE, the data can be reported according to different preset working modes. For example, the UWB horizontal angle measurement mode is defaulted to carry out data reporting. The UWB mobile phone shell works in a Case mode (only a UWB event is received: only horizontal angle information is received by default), the UWB TAG device (UWB TAG device) works in a Dongle mode (only a UWB event is sent) by default, the UWB mobile phone shell scans UWB TAG device information through UWB, and the mobile phone terminal acquires all scanned UWB TAG device information from the UWB mobile phone shell through BLE request. Therefore, through the adoption of the BLE connection mode, the mobile phone terminal and the UWB mobile phone shell are connected to transmit data, the UWB mobile phone shell simplifies the pairing operation between the mobile phone terminal and the mobile phone terminal in the using process, and quick and effective identification between the devices can be realized.

In one embodiment, the instructions sent by the electronic device to the ultra-wideband companion device or target ultra-wideband tag have the meaning shown in the following table:

For example, a user performs a shake-and-shake operation on a mobile phone (electronic device), the mobile phone responds to the shake-and-shake operation of the user (specified trigger operation), a displacement path of the sweeping robot is determined based on a target distance between the ultra-wideband corollary device and a target ultra-wideband tag, namely, a distance between the mobile phone and the sweeping robot (target controlled device), and an instruction of the displacement path is sent to the sweeping robot. And the sweeping robot receives the instruction of the displacement path and moves to the surrounding area where the mobile phone is located according to the displacement path to sweep.

The angle information of the candidate ultra-wide band tag and the ultra-wide band matching equipment is obtained by calculation of the ultra-wide band matching equipment according to an ultra-wide band protocol. The angle information is also the angle information between the electronic device to which the ultra-wideband matching device is attached and the controlled device in which the candidate ultra-wideband tag is located. The angle information may be angle information in a horizontal direction, angle information in a vertical direction, and angle information in the horizontal direction and the vertical direction.

For example, the angle information may be an offset angle between a horizontal direction of the electronic device and a horizontal direction of a controlled device in which the ultra-wide tape tag is located. As another example, the angle information may be an offset angle between a vertical direction of the electronic device and a vertical direction of a controlled device in which the ultra-wide tape tag is located.

In this embodiment, information of each candidate ultra-wideband tag sent by the ultra-wideband corollary equipment is obtained, and the information of each candidate ultra-wideband tag is obtained by scanning the ultra-wideband tag in a preset range in a first matching mode of the ultra-wideband corollary equipment.

In one embodiment, determining a target ultra-wideband tag based on each candidate ultra-wideband tag information comprises: responding to the pointing operation, comparing the angle information in the horizontal direction in each candidate ultra-wideband tag information with a preset angle threshold, identifying target ultra-wideband tag information from the candidate ultra-wideband tag information according to a comparison result, and taking the ultra-wideband tag corresponding to the target ultra-wideband tag information as a target ultra-wideband tag.

The angle information is included angle information between the ultra-wideband corollary equipment and the candidate ultra-wideband tag, and the preset angle threshold value can be an angle range which is set by a user in a user-defined mode, for example, the preset angle threshold value is within a range of plus or minus 30 degrees.

Under the condition that the ultra-wideband matching equipment is in the first matching mode, the electronic equipment responds to the pointing operation, compares the angle information in the horizontal direction in the candidate ultra-wideband tag information with a preset angle threshold value, identifies target ultra-wideband tag information from the candidate ultra-wideband tag information according to a comparison result, and takes the ultra-wideband tag corresponding to the target ultra-wideband tag information as a target ultra-wideband tag. The aim of the pointing operation is that a user performs pointing identification or pointing control on the internet of things equipment. Pointing identification or control, namely when the electronic equipment points to a certain equipment within a preset angle threshold range, the equipment can be quickly identified and controlled. For example, if the electronic device points to the air conditioner within the preset angle threshold range, the electronic device can identify the air conditioner from a plurality of internet of things devices and quickly start up a control interface of the air conditioner; the electronic equipment points to the sweeping robot within a preset angle threshold range, and the sweeping robot can be controlled to start for sweeping.

Specifically, the description will be given by taking an example in which the electronic device identifies the ultra-wide band tag. When the electronic equipment is a mobile phone terminal and the ultra-wideband matching equipment is an ultra-wideband mobile phone shell, and a user points the mobile phone terminal wearing the ultra-wideband mobile phone shell to a certain Internet of things equipment containing an ultra-wideband label within a preset angle threshold range, the mobile phone terminal can automatically acquire all candidate ultra-wideband label information scanned by the ultra-wideband mobile phone shell through the established wireless communication link. After the mobile phone terminal receives the candidate ultra-wideband tag information returned by the UWB mobile phone shell, the mobile phone terminal can compare the angle information in the horizontal direction in the candidate ultra-wideband tag information with a preset angle threshold value, and identify target ultra-wideband tag information from each candidate ultra-wideband tag information according to a comparison result, wherein the angle information is included angle information between the UWB mobile phone shell and each candidate ultra-wideband tag. For example, the ultra wide band corollary equipment is the UWB cell-phone shell, and its inside has the antenna, and the structure of arranging uses cell-phone terminal to erect the screen forward direction as 0 angle, and candidate ultra wide band label is the UWB label on certain thing networking device, and thing networking device and this UWB cell-phone shell direct connection on the horizontal direction are angle information with the contained angle of the forward direction that thing networking device set for. If wear the cell-phone terminal that has the UWB cell-phone shell, satisfy in certain angle range of product definition with the contained angle between the candidate ultra wide band label in the current space, for example positive and negative 15 degrees, then judge that the user is using this cell-phone terminal of wearing the UWB cell-phone shell, pointed to this candidate ultra wide band label, this candidate ultra wide band label is target ultra wide band label, then cell-phone terminal can discern the target controled equipment that this UWB label belongs to according to angle information, carry out data interaction with target controlled equipment again. Therefore, the problem that the equipment of different manufacturers cannot be identified is solved, the use experience of the user is improved, and convenience is brought to the user.

In an embodiment, as shown in fig. 5, before acquiring information of each candidate ultra-wideband tag returned by the ultra-wideband companion device, the method further includes:

step 502, in response to the start triggering operation, supplying power to the ultra-wideband accessory device, so that the ultra-wideband accessory device broadcasts pairing broadcast information containing identification information of the ultra-wideband accessory device and scans candidate ultra-wideband accessory tag devices within a preset range.

The user can wear or attach ultra wide band corollary equipment on electronic equipment, and electronic equipment responds to user's start trigger operation, supplies power to ultra wide band corollary equipment to make ultra wide band corollary equipment broadcast contain ultra wide band corollary equipment identification information pair broadcast information and scan the ultra wide band tape label in the scope of predetermineeing. For example, the description will be given taking an example in which a mobile phone terminal recognizes an ultra-wide band tag. Assuming that the electronic equipment is a mobile phone terminal and the ultra-wideband matching equipment is a mobile phone wearing shell, when a user triggers a power supply operation on the mobile phone wearing shell, the mobile phone terminal can respond to the starting triggering operation of the user, and the mobile phone terminal supplies power to the mobile phone wearing shell. The user's start trigger operation may include, but is not limited to, a tap operation, a click operation, a long-press operation, a pan-and-shake operation, and the like. The user can trigger the mobile phone terminal to supply power to the mobile phone wearing shell by double-clicking the mobile phone wearing the shell, namely the mobile phone terminal responds to the double-click operation of the user to supply wireless power to the mobile phone wearing shell and support the normal work of the UWB module of the mobile phone wearing shell. After the mobile phone terminal supplies power to the mobile phone wearing shell, the mobile phone wearing shell can enter a normal working state of the UWB module, the mobile phone wearing shell can send Bluetooth pairing broadcast information containing self equipment identification information, and an ultra-wide band label in a preset range can be scanned according to a UWB protocol. Therefore, the ultra-wideband corollary equipment is powered, so that the ultra-wideband corollary equipment can enter the normal working state of the ultra-wideband module, can establish quick and effective communication connection with electronic equipment, and can scan the ultra-wideband tape label in a preset range in real time.

And step 504, scanning the identification information of the ultra-wideband corollary equipment in the pairing broadcast information, and establishing a wireless communication link with the ultra-wideband corollary equipment.

Under the condition that the ultra-wideband corollary equipment sends pairing broadcast information containing ultra-wideband corollary equipment identification information and scans an ultra-wideband strap label in a preset range, namely under the condition that the ultra-wideband corollary equipment is in a normal working mode. The electronic device may power the ultra-wideband companion device in response to a start-trigger operation. In addition, the ultra-wideband companion device may also be self-powered or powered by other devices. The power supply means that the ultra-wideband corollary equipment is powered on. The paired broadcast information refers to that the equipment periodically sends message information in the broadcast according to a preset protocol. For example, each time a device broadcasts, the same message may be sent on a different broadcast channel, which is referred to as a broadcast event.

The ultra-wideband corollary equipment identification information is used for identifying the unique equipment. The identification information of the ultra-wideband corollary equipment in the application is used for identifying the identity authentication information among the ultra-wideband corollary equipment, for example, the identification information of the ultra-wideband corollary equipment can be a character string, a binary field or self-defined identification information. The electronic device judges whether to establish a wireless communication link according to the specific identification information, namely the electronic device establishes the wireless communication link with the device corresponding to the identification information according to a preset protocol or rule when the scanned identification information accords with the preset rule or the matching condition. After the wireless communication link is established between the devices, all data communication is performed in Connection Events.

For example, the description will be given taking an example in which a mobile phone terminal recognizes an ultra-wide band tag. Assuming that the electronic equipment is a mobile terminal, the mobile terminal can be a mobile phone terminal, the ultra-wideband matching equipment is a mobile phone wearing shell, and when a user triggers a power supply operation on the mobile phone wearing shell, the mobile phone terminal scans identification information of the mobile phone wearing shell in the paired broadcast information and establishes communication connection with the mobile phone wearing shell. Meanwhile, the mobile phone wearing shell can scan the ultra-wideband label information within a preset range according to a UWB protocol. The Bluetooth pairing broadcast information is in a Bluetooth wireless connection mode, and Bluetooth refers to a Bluetooth Low Energy (BLE) technology.

Specifically, when the electronic device is a mobile phone terminal and the ultra-wideband supporting device is a mobile phone wearing shell a, the mobile phone wearing shell a can send bluetooth matching broadcast information containing identification information of the mobile phone wearing shell a, and the mobile phone wearing shell a enters a broadcast state. The mobile phone terminal can enter a scanning state through real-time scanning, namely, the mobile phone terminal actively searches the broadcasting Bluetooth device and matches the identification information of the mobile phone wearing shell A in the broadcasting information with the identification information locally recorded by the mobile phone terminal. If the identification information of the mobile phone wearing shell A is recorded in the mobile phone terminal locally, which indicates that the mobile phone terminal and the mobile phone wearing shell A have an association relationship or a binding relationship, the mobile phone terminal can establish communication connection with the mobile phone wearing shell A according to the identification information of the mobile phone wearing shell A in the scanned pairing broadcast information. If the identification information of the mobile phone wearing shell A is not recorded locally, which indicates that the mobile phone terminal and the mobile phone wearing shell A do not have a binding relationship or an association relationship, the mobile phone terminal can bind the identification information of the mobile phone wearing shell A in the scanned pairing broadcast information with the identification information corresponding to the mobile phone terminal, establish communication connection with the mobile phone wearing shell A after the binding is successful, and store the identification information of the mobile phone wearing shell A in a local storage of the mobile phone terminal. Wherein, identification information wears shell A's only hardware identification for the cell-phone, and communication connection can adopt bluetooth wireless connection's mode, also can adopt other connected modes in this application, for example wifi's P2P connected mode etc.. Wherein, the cell-phone is worn shell A and can be UWB cell-phone shell, then carries specific equipment identification code in the BLE broadcast that UWB cell-phone shell sent, indicates that current equipment type is UWB cell-phone shell. The mobile phone terminal analyzes and filters the identification code, and only the UWB mobile phone shell equipment can be concerned in the connection process.

Step 506, sending a control command to the ultra-wideband accessory device through the established wireless communication link, where the control command is used to request to acquire the scanned ultra-wideband tag information.

The electronic equipment scans the identification information of the ultra-wideband matching equipment in the matching broadcast information, after a wireless communication link is established with the ultra-wideband matching equipment, the electronic equipment sends a control command to the ultra-wideband matching equipment through the established wireless communication link, and the control command is used for requesting to acquire the scanned ultra-wideband label information. Under the condition that the ultra-wideband corollary equipment normally works, namely the ultra-wideband corollary equipment can scan the ultra-wideband tag in a preset range in real time according to an ultra-wideband protocol, when a user wants to trigger, position and identify the internet of things equipment, the triggering operation of the user can be pointing operation, and angle information corresponding to the pointing operation needs to meet a preset angle threshold condition, for example, the angle threshold condition is that an angle between the ultra-wideband tag and the ultra-wideband corollary equipment is in a preset angle range, for example, the angle between the ultra-wideband tag and the ultra-wideband corollary equipment is in a range of plus or minus 30 degrees due to the pointing operation. For example, when a user directs a mobile phone terminal with a mobile phone wearing shell to a certain internet of things device within a preset angle range (plus or minus 30 degrees), the mobile phone terminal can automatically send a control command to the wearing shell through an established communication connection, and the control command is used for requesting to acquire scanned ultra-wideband label information so as to identify target ultra-wideband label information.

The description will be given by taking an example in which the mobile phone terminal recognizes the ultra-wide band tag. Supposing that the electronic equipment is a mobile phone terminal, when the ultra-wideband corollary equipment is an ultra-wideband mobile phone shell, supposing that a user directs a mobile phone terminal with the ultra-wideband mobile phone shell to a controlled device (the controlled device is provided with an ultra-wideband tag), namely when the user triggers, positions and identifies the controlled device, the mobile phone terminal can automatically send a control command to the ultra-wideband mobile phone shell through an established wireless communication link, when the ultra-wideband mobile phone shell receives the control command sent by the mobile phone terminal, the ultra-wideband mobile phone shell can identify the target ultra-wideband tag information from the candidate ultra-wideband tag information, namely, the mobile phone terminal identifies a target ultra-wideband tag information directed by the mobile phone terminal with the ultra-wideband mobile phone shell, and after the ultra-wideband tag information is received by the mobile phone terminal, the mobile phone terminal can identify the target ultra-wideband tag information from the candidate ultra-wideband tag information based on the candidate ultra-wideband tag information, namely, the mobile phone terminal identifies the target ultra-wideband tag information directed by the user And the target controlled equipment where the label is located.

Further, after the mobile phone terminal identifies the target ultra-wideband tag information from the plurality of candidate ultra-wideband tag information, the mobile phone terminal may automatically send a control instruction to the target controlled device having an association relationship with the identified target ultra-wideband tag information, that is, the mobile phone terminal identifies the target controlled device in which the target ultra-wideband tag is located, and the control instruction is used for controlling the target controlled device. For example, when a user directs a mobile phone terminal wearing a UWB mobile phone case to an air conditioner a attached with a target UWB tag within a preset angle range, the user can quickly turn on a control interface of the air conditioner a. Assuming that the user points the mobile phone terminal wearing the UWB mobile phone case to the air conditioner a attached with the target ultra-wide band tag within a preset angle range, the mobile phone terminal receives the ultra wide band TAG information returned by the UWB mobile phone shell, wherein the angle information of TAG 1 is 40 degrees, the angle information of TAG2 is 29 degrees and the angle information of TAG3 is 60 degrees, the mobile phone terminal identifies target ultra-wideband label information from a plurality of candidate ultra-wideband label information according to preset angle information (the angle threshold value is within a range of plus or minus 30 degrees), namely, the mobile phone terminal recognizes the target ultra-wide band TAG information as TAG2 from TAG 1, TAG2 and TAG3, the TAG2 has a correlation with the air conditioner A, the TAG2 can be attached to the air conditioner A, the mobile phone terminal can automatically send a control instruction to the air conditioner A attached with the TAG2, and a control interface corresponding to the air conditioner A is displayed in a display interface of the mobile phone terminal. In addition, the mobile phone terminal can also send a customized control command to the identified target internet of things device, namely the air conditioner A, through the network in the called control interface of the air conditioner A so as to switch the working mode of the air conditioner A. It can be understood that the ultra-wide band tag plays a role in positioning and identifying the controlled device, the target ultra-wide band tag and the target controlled device do not establish any communication connection, and the controlled device is not controlled through the ultra-wide band tag.

In addition, if the mobile phone terminal identifies a plurality of target ultra-wide band tag information from the angle information of the plurality of candidate ultra-wide band tag information according to the preset angle threshold, the mobile phone terminal may further select the target ultra-wide band tag information meeting the identification rule from the plurality of target ultra-wide band tag information according to the preset identification rule. For example, the preset angle threshold is within a range of plus or minus 30 degrees, the angle information of TAG 1, which is received by the mobile phone terminal and returned by the UWB mobile phone shell, is 20 degrees, the angle information of TAG2 is 29 degrees, and the angle information of TAG3 is 60 degrees, so that the mobile phone terminal recognizes two target ultra-wide TAG information from TAG 1, TAG2, and TAG3 according to the preset angle threshold (the angle threshold is within the range of plus or minus 30 degrees), that is, the mobile phone terminal recognizes that both TAG 1 and TAG2 meet the preset angle threshold condition, the mobile phone terminal can further select TAG 1 of the minimum angle information as the final target ultra-wide TAG information according to the preset recognition rule, assuming that the recognition rule is the minimum angle information meeting the angle threshold, and the mobile phone terminal can select TAG 1 of the minimum angle information from TAG 1 and TAG2 according to the recognition rule. It can be understood that the identification rule in the application is not limited to identifying the minimum angle information meeting the angle threshold condition, but also can be according to the time sequence of the scanned ultra-wide tape tag information, or can display the control interfaces of a plurality of identified internet of things devices attached with target ultra-wide tape tag information on a screen, and the identification rule can be set by user self-definition.

In the traditional identification mode among devices, different manufacturers integrate UWB functions in the mobile phone, namely UWB hardware is integrated in the mobile phone, when the UWB hardware is used in the mobile phone, opposite-end devices need to be found, but an agreed protocol field is well defined and cannot be changed randomly, and the mobile phone manufacturers and the function protocols are not unified in the market, so that the UWB-technology-based interaction among different users cannot be met, and the devices produced by different manufacturers cannot be effectively identified.

In this embodiment, when the ultra-wideband accessory transmits pairing broadcast information including ultra-wideband accessory identification information and scans an ultra-wideband tag within a preset range, the electronic device scans the ultra-wideband accessory identification information in the pairing broadcast information and establishes a wireless communication link with the ultra-wideband accessory. The control command is sent to the ultra-wideband corollary equipment through the established wireless communication link, the control command is used for requesting to acquire scanned ultra-wideband label information, so that the electronic equipment identifies ultra-wideband labels under the assistance of the ultra-wideband corollary equipment, and the target equipment is quickly and accurately determined according to the information between the ultra-wideband labels and the target equipment.

In one embodiment, the method further comprises: and under the condition that the power supply time reaches the time threshold, stopping supplying power to the ultra-wideband corollary equipment.

In one embodiment, scanning for ultra-wideband companion device identification information in the pairing broadcast information to establish a wireless communication link with the ultra-wideband companion device comprises: acquiring ultra-wideband corollary equipment identification information in the paired broadcast information; if the identification information of the ultra-wideband corollary equipment is found in the local storage, a wireless communication link is established with the ultra-wideband corollary equipment; and if the identification information of the ultra-wideband corollary equipment is not found in the local storage, binding the identification of the ultra-wideband corollary equipment with the equipment identification of the electronic equipment, establishing a wireless communication link with the ultra-wideband corollary equipment after the binding is successful, and storing the identification of the ultra-wideband corollary equipment in the local storage.

In one embodiment, the ultra-wideband companion device identification information carries device type information; after the identification information of the ultra-wideband matching device in the pairing broadcast information is acquired, the method further comprises the following steps: and under the condition that the ultra-wideband corollary equipment is determined to be ultra-wideband equipment according to the equipment type information carried by the ultra-wideband corollary equipment identification information, executing the step of searching the ultra-wideband corollary equipment identification information in local storage.

And detecting double click of the mobile phone terminal, triggering wireless reverse charging, and starting BLE scanning by the mobile phone terminal. The UWB mobile phone shell is started after receiving the wireless reverse charging to obtain the electric quantity, immediately starts BLE and sends BLE broadcast, and simultaneously starts to scan UWB TAG equipment in the current environment according to a UWB protocol. When the mobile phone terminal scans the broadcast information sent by the UWB mobile phone shell, the BLE is used for connecting the UWB mobile phone shell. After the Bluetooth connection between the mobile phone terminal and the UWB mobile phone shell is successful, the mobile phone terminal sends a binary string of a control command (0xAABC04) to the UWB mobile phone shell through BLE to request to acquire the TAG scanning information. The UWB handset shell transmits the scanned UWB TAG device information to the handset terminal through BLE, and the transmission protocol is a data protocol shown in table 1, for example, a data format of (0xAA05) is currently transmitted. Under the normal operating condition of UWB cell-phone shell, when the user wants to trigger the location discernment thing networking device, the user can point to target UWB TAG equipment with the cell-phone terminal of wearing UWB cell-phone shell.

The mobile phone terminal responds to the pointing operation of a user, compares the received angle information in the candidate ultra-wideband label information returned by the UWB mobile phone shell with a preset angle threshold, and identifies target ultra-wideband label information from the candidate ultra-wideband label information according to a comparison result, namely, the mobile phone terminal can identify the target UWB TAG equipment pointed by the user through the angle information. Therefore, the problem that the equipment of different manufacturers cannot be identified is solved, the use experience of the user is improved, and convenience is brought to the user.
