Among them, Near Field Communication (NFC) is a short-range high-frequency wireless Communication technology that allows contactless point-to-point data transmission (within ten centimeters) between electronic devices to exchange data. NFC technology evolved from contactless Radio Frequency Identification (RFID) and is downward compatible with RFID. The NFC label is a passive device without a power supply, when the NFC label is used, the NFC reader-writer is in contact with the NFC label, the NFC label obtains a very small circuit of the power supply driving label from the NFC reader-writer, and storage information is transmitted to the NFC reader-writer. The stored information, which may also be a small amount of text or other data, may direct the NFC reader to a certain web address (URL). Wearable equipment includes the main part and wears the subassembly, the main part with wear the detachable connection of subassembly. The communication distance refers to the physical distance between the NFC tag in the wearing component and the NFC reader-writer in the main body, and when the NFC reader-writer is located at the point A and the NFC tag is located at the point B, the communication distance between the main body and the wearing component refers to the straight-line distance between the point A and the point B. The communication distance can be set by engineers according to actual requirements in a self-defining way, and is set to be 0-10cm in principle. The storage information refers to data stored in the NFC tag, and may include a wearing component identifier and may further include a display theme parameter corresponding to the wearing component identifier.
Specifically, when the communication distance between the NFC reader and the NFC tag is lower than the distance threshold, the NFC reader inside the main body of the wearable device generates a radio frequency field, and the NFC tag responds to the radio frequency field. At this time, the NFC reader/writer can read the storage information stored in the NFC tag. The stored information may be a pre-stored wearing component identifier, which corresponds to a display theme. The main body can acquire a preset list, and wearing component identifications which can be identified by the main body are stored in the preset list. When the wearing component identifier belongs to an identifier which can be identified by the main body, the main body can acquire the theme display data packet corresponding to the wearing component identifier. In addition, the storage data of the NFC tag may further include: and the NFC reader-writer of the main body writes in the mark according to the main body mark. When the NFC reader of the main body writes the write-in identifier in the NFC tag in the wearing component, the main body and the wearing component can be bound. When the main body detects that the stored data includes the writing identifier in addition to the wearing component identifier, it is necessary to detect the correspondence between the writing identifier and the body identifier. When the writing identifier is matched with the body identifier, the writing identifier is written before the NFC reader-writer in the body, the wearing component is in a binding relation with the body, and the main body can determine a target display theme according to the wearing component identifier. When the written identifier is not matched with the body identifier, the written identifier is written by other NFC readers before, the wearing component is not bound with the body, and the main body can determine the corresponding target display theme according to the unidentifiable wearing component identifier.
And step 204, determining a target display theme according to the stored information.
The display theme may include standby pictures, screen savers, ring tones, and operation interfaces and icons. The target display theme is a display theme corresponding to the color, design and/or style of the wearing component.
Specifically, the main body reads the storage information in the recognizable wearing component and finds the corresponding target display theme according to the storage information. For example, the wearing component may store a target display theme corresponding to the storage information, and when the main body reads the storage information, the main body may acquire the target display theme corresponding to the storage information. The main body is internally stored with at least one target display theme data packet, and when the main body corresponds to the wearing assembly, a target display theme corresponding to the wearing assembly is stored in the main body; when the main body has a plurality of wearing components capable of being matched, when the stored information in any one of the wearing components is identified, the target display theme corresponding to the any one wearing component identification is searched. The display theme data packet corresponding to the storage information of the wearable component capable of being identified is stored in the cloud server, and when the main body reads the storage information in the wearable component, a request is sent to the cloud server to acquire the target display theme corresponding to the storage information.
And step 206, switching the current display theme to a target display theme.
Specifically, the subject obtains a target display theme corresponding to the stored information from the wearable component, the local server, or the cloud server.

When the fact that the communication distance between the NFC tag and the reader-writer is lower than a distance threshold value is detected, the main body of the wearable device reads storage information in the NFC tag through the NFC reader-writer, the storage information carries an identification corresponding to a target display theme, the main body determines the target display theme according to the storage information, and switches the current display theme to the target display theme. When the wearing components are switched, the main body automatically switches the display themes according to the switched wearing components, and the display theme switching efficiency is improved.

The subject looks up in a preset list whether the wearing component identification exists. When the preset list contains the wearing component identifier, the main body can identify the wearing component and can adapt to the corresponding target display theme according to the wearing component identifier. When the preset list does not contain the wearing component identifier, the main body cannot identify the wearing component and cannot adapt to the corresponding target display theme according to the wearing component identifier.
And step 304, when the preset list contains the wearing component identification, determining a target display theme according to the wearing component identification.

Specifically, the preset list may further include a display theme corresponding to each recognizable wearing component identifier of the subject. Namely, the preset list includes: the main body, the identifiable wearing component identification and the identifiable display theme corresponding to the wearing component identification are related. The main part reads the storage information in the NFC label in the wearing component, analyzes the storage information to acquire the wearing component identification, detects whether the preset list contains the wearing component identification, if so, the wearing component identification is identified as a recognizable wearing component identification, and the main part can search the corresponding target display theme in the preset list according to the wearing component identification.

By way of illustration and not limitation, RAM is available in a variety of forms, such as Static RAM (SRAM), Dynamic RAM (DRAM), Synchronous DRAM (SDRAM), double data rate SDRAM (DDR SDRAM), Enhanced SDRAM (ESDRAM), synchronous Link (Synchlink) DRAM (SLDRAM), Rambus Direct RAM (RDRAM), direct bus dynamic RAM (DRDRAM), and bus dynamic RAM (RDRAM).
The application provides a wearable device wearing assembly, which comprises an NFC label and is used for responding to a radio frequency field emitted by an NFC reader-writer of a wearable device main body and providing storage information, wherein the radio frequency field is a field generated when the main body detects that the communication distance between the main body and the wearable device wearing assembly is lower than a distance threshold. The storage information is used for indicating the main body to determine a target display theme according to the storage information and switching the current display theme into the target display theme.
Specifically, when the communication distance between the NFC reader and the NFC tag is lower than the distance threshold, the NFC reader inside the main body of the wearable device generates a radio frequency field, and the NFC tag responds to the radio frequency field. At this time, the NFC reader/writer can read the storage information stored in the NFC tag. The stored information may be a pre-stored wearing component identifier, which corresponds to a display theme. The main body obtains a preset list after reading the storage information, and the wearing component identification which can be identified by the main body is stored in the preset list. When the wearing component identifier belongs to an identifier which can be identified by the main body, the main body can acquire the theme display data packet corresponding to the wearing component identifier and switch the currently running display theme to the target display theme.
In one embodiment, as shown in fig. 8, NFC tag 802 includes: a second NFC coil 8021 and a second ferrite 8022, the second NFC coil 8021 being arranged around the second ferrite 8022.
Specifically, the NFC tag 802 includes: a second NFC coil 8021 and a second ferrite 8022, and the second NFC coil 8021 is disposed around the second ferrite 8022. The second NFC coil 8021 feeds power inside the wearing component, so that the second NFC coil 8021 can be used as an antenna radiator to realize reception and transmission of signals, and the radiation direction includes up, down, left, and right directions. The NFC tag 802 can receive read and write operations of the NFC reader 801 in response to a radio frequency field generated by the NFC reader 801 through the second NFC coil 8021. In addition, the second ferrite 8022 may be a plurality of ferrites side by side, and the radiation intensity of the second NFC coil 8021 can be enhanced by increasing the number of the second ferrites 8022. In this embodiment, the second NFC coil 8021 is disposed around the second ferrite 8022, so that the magnetic flux of the second NFC coil 8021 is increased, and the communication performance and the radiation distance of the second NFC coil 8021 as an antenna radiator are further improved.
