[0002] Traditional scanning devices (such as digital impression machines) typically require scanning QR codes or using wired connections to pair with their bases. These processes are often cumbersome, time-consuming, and susceptible to environmental interference, affecting pairing efficiency and stability. Furthermore, traditional scanning devices generally rely on electromagnetic induction technology for charging, requiring the device to be tightly attached and aligned. Because this technology demands extremely precise alignment, it increases operational complexity and the difficulty of cleaning and maintaining the device interface, reducing charging convenience and impacting charging efficiency as well as the efficiency of data transmission.

[0008] In some embodiments of this application, the pairing with the base using near-field communication technology includes: upon receiving pairing requests from multiple bases, obtaining the distance between the scanning device and each of the multiple bases; and establishing a connection relationship between the base closest to the scanning device as the first target base and the first target base.

[0009] In some embodiments of this application, after designating the base closest to the scanning device as the first target base, the method further includes: establishing a connection relationship with the first target base in response to a confirmation operation; wherein the confirmation operation is triggered based on a prompt message issued by the first target base, the prompt message being used to indicate that the first target base is the base closest to the scanning device.

The scanning device records charging data and sends the charging data to the designated device via the base, thereby improving the data transmission efficiency of the charging data. To a certain extent, this improves the data processing efficiency of the designated device in response to the charging data, enabling timely and effective management of the scanning device.

[0026] For ease of understanding, some concepts related to the embodiments of this application are illustrated and explained by way of example for reference.

[0027] It should be noted that in this application, "at least one" means one or more, and "more than one" means two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural. The terms "first," "second," "third," "fourth," etc. (if present) in the specification, claims, and drawings of this application are used to distinguish similar objects, not to describe a specific order or sequence.

[0028] Traditional scanning devices (such as digital impression machines) typically require scanning QR codes or using wired connections to pair with their bases. For example, pairing via QR code scanning requires the user to scan both the QR code on the scanning device and / or the QR code on the base. This method is cumbersome, requiring the user to hold the device and activate the scanning function, and is also susceptible to ambient light conditions, affecting pairing stability. Wired pairing relies on a physical cable, reducing the device's operational flexibility. Furthermore, cable damage and line loss can also affect pairing and data transmission. Therefore, pairing via QR code scanning or wired connections is often cumbersome, time-consuming, and susceptible to environmental interference, impacting pairing efficiency and stability.

[0029] In addition, traditional scanning equipment generally relies on electromagnetic induction technology for charging. Since electromagnetic induction technology has extremely strict requirements for the precise alignment of the charging position, it increases the complexity of operation and the difficulty of cleaning and maintaining the device interface, reduces the convenience of charging, and affects the charging efficiency and the data transmission efficiency of charging data.

[0030] Therefore, this application provides a data transmission method, a scanning device, a scanning system, and a storage medium, which can pair with a base using Near Field Communication (NFC) technology to achieve accurate and efficient pairing. Furthermore, by using magnetic resonance wireless charging technology, a contactless charging mode can be achieved between the scanning device and the base, improving charging and data transmission efficiency. This also reduces the battery weight of the scanning device to some extent, lowering the device cost.

[0031] To better understand the data transmission method, scanning device, and storage medium provided in the embodiments of this application, the application scenarios of the data transmission method of this application are described below.

[0032] Figure 1This is a schematic diagram illustrating an application scenario of the data transmission method provided in this application embodiment. The data transmission method provided in this application embodiment is applied to a scanning device 10, which can communicate with multiple bases 20, and each base 20 communicates with a designated device 30.

[0033] The communication connection methods can include wired and wireless communication connections.

[0034] The scanning device 10 may include, but is not limited to, oral scanning devices (e.g., digital impression instruments), facial scanning devices, CT (Computed Tomography) scanning devices or CBCT (Cone Beam Computer Tomography) scanning devices, professional scanners, industrial scanners, etc. Oral scanning devices include intraoral scanners and extraoral scanners. The scanning device 10 may be a handheld scanning device or a fixed scanning device. The scanning device 10 can realize three-dimensional reconstruction of objects or scenes such as teeth, faces, bodies, industrial products, industrial equipment, cultural relics, works of art, prostheses, medical instruments, and buildings. This application does not limit this.

[0035] Each base 20 can be an adapter base or a charging dock for carrying the scanning device 10. Each base 20 has one or more functions such as charging, data transmission, device management and connection, physical placement and protection (e.g., providing a slot for placing the scanning device 10), and maintenance assistance. The charging function can be provided by, for example... Figure 7 The design of the base 20 and the wireless charging device 40 is integrated to support this. This application does not limit the shape, structure, or function of each base 20.

[0036] Each base 20 can be paired with at least one scanning device 10 via near-field communication technology. In one example, there are two scanning devices 10: an oral scanner and a facial scanner. The base 20 can be paired with the oral scanner and the facial scanner, respectively. Additionally, the oral scanner and the facial scanner can also be paired with each other to achieve data binding and avoid duplicate descriptions of the same object.

[0037] The designated device 30 can be a digital device, which includes computer equipment and non-computer equipment. Computer equipment may include mobile phones, tablets, smart wearable devices, augmented reality (AR) / virtual reality (VR) devices, laptops, netbooks, etc. Non-computer equipment may include dental scanning equipment (e.g., digital dental impression machines), facial scanning equipment, CT (Computed Tomography) scanning equipment or CBCT (Cone Beam Computer Tomography) scanning equipment, professional scanners, industrial scanners, etc. This application embodiment does not impose any limitations on the specific type of the designated device 30.

Each base 20 includes an NFC chip 210, an NFC sensor 220, a communication module 230, and a touch device 240. The touch device 240 may be an external module detachably connected to the main body of the base 20, or it may be a module fixedly integrated into the main body of the base 20. This application does not limit the form of the base 20 and the touch device 240. The touch area on the surface of the touch device 240 is used to receive user input operations, such as touching, tapping, long pressing, or clicking.

[0039] In some embodiments, after the NFC chip 110 of the scanning device 10 is woken up, it continuously emits a radio frequency field through the NFC sensor 120 and detects responses. When the base 20 enters the radio frequency field range, the NFC chip 210 is activated. Subsequently, based on the Near Field Communication (NFC) protocol, the scanning device 10 completes a communication handshake with the NFC chip 210 and NFC sensor 220 of the base 20 through the NFC chip 110 and NFC sensor 120, and establishes a stable data connection. When the data volume is small, the scanning device 10 can transmit its own relevant data to the base 20 through the NFC chip 110. When the data volume is large, the scanning device 10 can transmit its own relevant data to the base 20 through the communication module 130. The base 20 receives the relevant data sent by the scanning device 10 through the NFC chip 210 or the communication module 230, and transmits the data sent by the scanning device 10 to the designated device 30 through the communication module 230.

[0040] In another embodiment, a touch device 240 may be provided on the base 20, and the NFC chip 210 of the base 20 can be woken up by performing touch operations such as clicking or pressing on the touch device 240. The NFC chip 210 of the base 20 can also be woken up when powered on, and this application does not limit the method in which the NFC chip 210 is woken up.

[0041] After the NFC chip 210 of the base 20 is woken up, it continuously emits a radio frequency field through the NFC sensor 220 and detects responses. When the scanning device 10 enters the radio frequency field range, the NFC chip 110 is activated. Subsequently, based on the Near Field Communication (NFC) protocol, the scanning device 10 completes a communication handshake with the NFC chip 210 and NFC sensor 220 of the base 20 through the NFC chip 110 and NFC sensor 120, and establishes a stable data connection. When the data volume is small, the scanning device 10 can transmit its relevant data to the base 20 through the NFC chip 110. When the data volume is large, the scanning device 10 can transmit its relevant data to the base 20 through the communication module 130. The base 20 receives the relevant data sent by the scanning device 10 through the NFC chip 210 or the communication module 230, and transmits the data sent by the scanning device 10 to the designated device 30 through the communication module 230.

[0042] In some optional embodiments of this application, the scanning device 10 may include an NFC chip 110 and a communication module 130. Each dock 20 includes an NFC sensor 220, a communication module 230, and a touch device 240. The scanning device 10 can establish a connection with the NFC sensor 220 of each dock 20 via the NFC chip 110.

[0043] In some optional embodiments of this application, the scanning device 10 may include an NFC sensor 120 and a communication module 130. Each dock 20 includes an NFC chip 210, a communication module 230, and a touch device 240. The scanning device 10 can establish a connection with the NFC chip 210 of each dock 20 through the NFC sensor 120. In other embodiments of this application, to further ensure the security of the connection, the scanning device 10 may verify the security of the connection before establishing a connection with each dock 20 using a security verification method. The security verification method includes, but is not limited to, exchanging encryption credentials or digital certificates.

Figure 2 Other major components of the scanning device 10 are described.

[0045] Figure 2 This is a schematic diagram of the scanning device provided in an embodiment of this application.

[0048] In some embodiments, the NFC chip 110 integrates trigger logic, allowing it to continuously emit a radio frequency field and detect responses via the NFC sensor 120 when the NFC chip 110 is woken up. When the NFC sensor 120 detects the presence of an external device (such as...) within its magnetic field range... Figure 1 When the device signal meets the preset trigger conditions (as shown in the base 20), the NFC chip 110 will automatically execute the corresponding trigger action.

[0050] The scanning head 140 can be a component detachably connected to the scanning device 10, and has the function of being able to be inserted into and removed from the scanning device 10. The scanning head 140 can scan the object being scanned, thereby acquiring the scan data of the object being scanned. The object being scanned can be teeth, a face, a body, industrial products, industrial equipment, cultural relics, works of art, prostheses, medical instruments, buildings, etc., and this application does not limit this. The scanning head 140 can be provided with a memory 1401 for storing data on the number of times the scanning head 140 has been used, data on the number of times it has been disinfected, scan data, or other data.

[0061] It is understood that the structure illustrated in the embodiments of this application does not constitute a specific limitation on the scanning device 10.

[0062] Figure 3 This is a flowchart of a data transmission method provided in an embodiment of this application, applied in a scanning device (e.g., Figure 1 and Figure 2 The scanning device 10). Depending on different needs, the order of the steps in this flowchart can be changed, and some steps can be omitted.

[0063] Step S301: Pair with the base using near field communication technology.

[0064] In some embodiments of this application, Near Field Communication (NFC) technology is a short-range wireless communication technology that can establish a short-range wireless connection between two devices.

[0065] To achieve fast, stable, and convenient pairing between the scanning device and the dock, NFC chips can be installed in both the scanning device and the dock. The NFC chips in both devices enable rapid pairing.

[0066] In some embodiments of this application, the scanning device can actively detect a dock in the environment. When the NFC chip of the scanning device is activated, it continuously emits a radio frequency field through the NFC sensor of the scanning device and detects the response. When the NFC sensor of the scanning device detects the presence of an external device, such as a dock, within its magnetic field range, and the NFC chip of the scanning device determines that the response signal emitted by the dock meets preset trigger conditions, the NFC chip of the scanning device will automatically perform an NFC communication protocol handshake with the dock to complete pairing.

[0067] The NFC sensor on the scanning device can detect the identifier (such as a Wi-Fi password) of the base by parsing the response signal. If the identifier matches the pre-stored authorization information, the base is deemed to meet the trigger conditions. Alternatively, a physical button can be installed on the scanning device for secondary confirmation. If the scanning device detects the presence of a base within its magnetic field range and that it has already been authenticated, and if it detects that the user has clicked the physical button, it determines that the base meets the trigger conditions. The NFC chip on the scanning device will then automatically perform an NFC communication protocol handshake with the base to complete the pairing.

[0068] In some embodiments of this application, the scanning device can be configured to be in NFC mode, listening for and responding to pairing requests initiated by the dock. When the scanning device is woken up and in NFC mode, it receives a pairing request broadcast by the dock, extracts the dock's identifier from the pairing request, and verifies the identifier to determine whether to automatically perform an NFC communication protocol handshake with the dock. If the verification is successful, the scanning device will automatically perform an NFC communication protocol handshake with the dock to complete the pairing; if the verification fails, the scanning device will not pair with the dock.

[0069] The scanning device may include an ultrasonic ranging sensor for measuring the distance between the ultrasonic ranging sensor and the base, i.e., the distance between the scanning device and the base. When the scanning device receives pairing requests from multiple bases, the ultrasonic ranging sensor can be used to obtain the distance between the scanning device and each of the multiple bases. In one example, the ultrasonic ranging sensor periodically emits brief high-frequency sound waves that propagate through the environment. If a sound pulse from the high-frequency sound wave hits an object (such as a base), it is reflected back to the ultrasonic ranging sensor, which can then calculate the distance between itself and the object based on the emission and reception times of the sound pulse.

[0070] The scanning device can complete pairing based on distance. Specifically, the base closest to the scanning device is designated as the first target base, and the scanning device automatically establishes a connection with the first target base based on the distance. The following section will combine... Figure 4 Describe it.

[0071] like Figure 4 The application scenario shown involves a scanning device 10 and four bases 20, namely, a first base 20, a second base 20, a third base 20, and a fourth base 20. When the scanning device 10 receives pairing requests from these four bases 20, it obtains the distance between the scanning device 10 and each base 20. It calculates the distances L1 between the scanning device 10 and the first base 20, L2 between the scanning device 10 and the second base 20, L3 between the scanning device 10 and the third base 20, and L4 between the scanning device 10 and the fourth base 20. The relationships between these distances are: L1 < L2 < L3 < L4. Therefore, the first base 20 can be designated as the first target base, and the scanning device 10 automatically pairs with the first base 20.

[0072] In other embodiments of this application, combined with Figure 4 As shown, each base 20 can be equipped with an indicator light or other status indicator. Figure 4 (Not shown in the image) The prompt message is emitted through lighting, vibration, sound, or other means. Alternatively, the scanning device 10 may be equipped with an indicator light or other status indicator corresponding to each base 20, but no indicator light or other status indicator may be configured on each base 20. Alternatively, both each base 20 and the scanning device 10 may be equipped with indicator lights or other status indicators; this application does not limit this.

[0073] Taking the example of setting an indicator light on each base 20, when the scanning device 10 enters the magnetic field range of the base 20, the base 20 can display the indicator light. For example, when the scanning device 10 enters the magnetic field range of the first base 20, the first base 20 displays the indicator light. By displaying the indicator light, the user can intuitively and quickly locate the base to be paired. If the scanning device 10 enters the corresponding magnetic field range of multiple bases 20, all of the multiple bases 20 will display their own indicator lights. Continuing the above example, if the scanning device 10 receives pairing requests from these four bases 20, it means that the scanning device 10 is within the magnetic field range of these four bases 20, and these four bases 20 will all display their own indicator lights. In addition, these four bases 20 can generate different status indications based on distance. For example, the base closest to the scanning device 10 can be displayed by flashing the indicator light, while the other three bases that are farther away can be displayed by statically displaying the indicator light. Furthermore, bases 20 at different distances can also be distinguished by the color, brightness, and flashing frequency of the indicator light, which is not limited in this application. In other embodiments of this application, after determining the distance between the scanning device and each base, the scanning device may also establish a connection with the first target base in response to a confirmation operation. The confirmation operation is triggered by a prompt message issued by the first target base, indicating that the first target base is the base closest to the scanning device.

[0074] Combination Figure 4 As shown, the first target base is identified as the first base 20, which is indicated by a flashing indicator light. The user performs a confirmation operation on the scanning device 10 through the display of the first base 20, thereby establishing a connection between the scanning device 10 and the first base 20. This confirmation operation can be generated by clicking a hardware button on the scanning device 10, by touching a control on the display interface of the display device on the scanning device 10, or by the scanning device 10 receiving confirmation information from a designated device (such as a computer). This application does not limit the scope of this method.

[0075] In other embodiments of this application, after determining the first target base but before establishing a connection between the scanning device and the first target base, the scanning device can switch the first target base to a second target base, thereby establishing a connection between the scanning device and the second target base. Specifically, in response to a switching operation, the scanning device acquires the second target base indicated by the switching operation, which includes one or more operations such as gesture operation, touch operation, and click operation. Based on the switching operation, the scanning device establishes a connection with the second target base. The second target base is any one of multiple bases other than the first target base.

[0076] Combination Figure 4 As shown, the first target base is the first base 20, which is displayed by flashing indicator lights to indicate that it is the closest base to the scanning device. The user can switch between the two bases by clicking a hardware button on the scanning device 10 or using controls on its display. In response, the scanning device 10 acquires the second target base, for example, determining the second base 20 based on distance. In this case, the scanning device 10 establishes a connection with the second base 20.

[0077] In some embodiments of this application, after the scanning device establishes a connection with the first target base, that is, after the scanning device is paired with the first target base, it can perform a switching operation to switch to pairing with other bases. The switching operation includes one or more of the following: gesture operation, touch operation, and click operation.

[0078] The scanning device may have physical buttons or touchable areas. When the scanning device detects a user's switching operation on the physical button or touchable area, it disconnects from the first target base and establishes a connection with the third target base indicated by the switching operation. The third target base is any one of the multiple bases except the first target base.

[0079] In one example, combining Figure 4 As shown, when the scanning device 10 has been paired with the first base 20, and the scanning device 10 is in the position as shown... Figure 4 Within the magnetic field range of the four bases 20 shown. When the scanning device 10 detects a switching operation, it disconnects from the first base 20 and, based on the distance between itself and the multiple bases 20, designates the second base 20 as the first target base, establishing a pairing relationship between the scanning device 10 and the second base 20.

[0080] In another example, combining Figure 4 As shown, the scanning device 10 can be paired with a base based on a switching operation instruction. When the scanning device 10 is already paired with the first base 20, and the scanning device 10 is in the position shown... Figure 4The magnetic field range of the four bases 20 shown. The display device of the scanning device 20 displays the bases that are currently allowed to be paired. When the scanning device detects a switching operation, it acquires the base indicated by the switching operation. For example, if the user clicks on the third base 20 through the display device, the scanning device 10 disconnects from the first base 20 and pairs with the third base 20. Alternatively, when the scanning device 20 is not equipped with a display device, it can display the bases that are currently allowed to be paired through a display device connected to the scanning device 20. After receiving an operation from the user on the external display device, the scanning device 20 generates a switching operation and acquires the base indicated by the switching operation in response to the switching operation.

[0081] In some embodiments of this application, each base is equipped with a touch device. The touch area on the surface of the touch device is used to receive user input operations, such as touching, long pressing, or clicking. By providing a touch device, the determinism of physical interaction can compensate for the ambiguity of purely wireless connections, while retaining the convenience of wireless technology, reducing pairing waiting time, and improving pairing efficiency and accuracy. Alternatively, the touch device can be independently mounted on the scanning device and not on the base. The touch device can also be mounted separately on both the base and the scanning device.

[0082] The scanning device can detect user intent and establish a pairing relationship by sensing the NFC chip of the other party through its NFC sensor. Taking an example where both the scanning device and the dock are equipped with NFC chips and NFC sensors, and the dock has a touch device, when the dock detects a user's touch operation on the touch area of ​​the dock, it wakes up the dock's NFC sensor. This NFC sensor, through a pairing trigger, activates the dock's NFC sensor to enter pairing mode. The dock's NFC sensor detects the scanning device's NFC chip and broadcasts a pairing request to the scanning device, thus completing the pairing relationship between the scanning device and the dock. Furthermore, the scanning device can store pairing information carried by pairing requests from different docks in its memory.

[0083] Taking a scanning device and a base both equipped with NFC chips and NFC sensors, and a touch device on the scanning device as an example, when the scanning device detects that the user performs a touch operation on the touch area of ​​the touch device, it wakes up the NFC sensor of the touch device. The NFC sensor triggers the NFC sensor of the scanning device to sense the NFC chip of the base through a pairing trigger, and stores all the pairing information of the bases sensed in the memory. Subsequently, pairing relationships can be established based on conditions such as distance. For example, the scanning device establishes a pairing relationship with the base that is closest to it.

[0084] If multiple docks exist, they can be designed to be in standby mode, meaning they do not actively send any pairing requests while in standby. If any dock detects a touch operation by the user, it enters wake-up mode from standby. Once in wake-up mode, the dock's NFC sensor is activated, triggering a broadcast pairing request. At this point, the scanning device detects this pairing request and completes the pairing process.

[0085] In one example, combining Figure 5 As shown, there are four bases 20 around the scanning device 10, and each of the four bases 20 is equipped with a touch device. The surface of the touch device is provided with a touch area (e.g., Figure 5 As shown in A). When no touch operation is performed on any of the bases 20, all four bases 20 are in standby mode. If the touch area A of the third base 20 detects a user touch operation, the third base 20 sends a pairing request. Upon receiving the pairing request, the scanning device 10 pairs with the base that sent the request; that is, the scanning device 10 pairs with the third base 20.

[0086] By incorporating a touchscreen, frequent pairing switching can be avoided. In one example, the scanning device automatically pairs with a first target base that is closest to it based on distance. However, the actual operating environment of the scanning device is the area where a second target base is located. Therefore, in such scenarios, the user needs to manually trigger a switching operation to change the base pairing. To avoid frequent switching, a touchscreen can be used to achieve precise pairing.

[0087] In some embodiments of this application, the scanning device can be pre-set with multiple pairing modes, such as a first mode and a second mode.

[0088] When multiple docks are confirmed to be in a wake-up state, in response to a mode selection operation, the scanning device's mode is set to the first mode, and the scanning device can automatically complete pairing based on the distance between itself and the docks. When multiple docks are confirmed to be in a standby state, in response to a mode selection operation, the scanning device's mode is set to the second mode, and the scanning device can automatically complete pairing based on a pairing request generated by a touch operation. The pairing modes described above are merely examples, and actual applications are not limited to these.

[0089] In step S302, when entering the alternating magnetic field generated by the wireless charging device, if the first frequency generated by the receiving coil of the scanning device matches the second frequency generated by the transmitting coil of the wireless charging device, a resonant magnetic field space is generated.

[0090] In some embodiments of this application, the wireless charging device can be a magnetic resonance charging plate, a desktop charging base, etc., and is a movable, detachable, and fixable charging device. This application does not limit the form of the wireless charging device. In a wireless working environment, magnetic resonance wireless charging can be used to reduce the battery weight of the scanning device through contactless, mid-range charging, making the scanning device more portable.

[0091] Among them, magnetic resonance wireless charging is a mid-range wireless power supply technology based on the principle of electromagnetic resonance coupling. Its core advantage lies in breaking through the "close-fitting" limitation of traditional electromagnetic induction charging, enabling multiple devices to charge simultaneously and having higher tolerance for different positions. It is a key technology direction for "desktop and space-level" wireless power supply. Therefore, by using magnetic resonance wireless charging technology, scanning equipment can be charged while in operation, achieving simultaneous use and charging, and improving the operational efficiency of scanning equipment.

[0092] In some embodiments of this application, the transmitting coil (also called the driving coil) of the wireless charging device is energized with high-frequency alternating current (typically 100kHz-1MHz) to generate an alternating magnetic field. When the scanning device enters this alternating magnetic field, that is, when the receiving coil of the scanning device enters the alternating magnetic field, if the first frequency (also called the natural frequency) generated by the receiving coil of the scanning device matches the second frequency (also called the natural frequency) generated by the transmitting coil of the wireless charging device, then the transmitting coil and the receiving coil form a magnetic resonant coupling (similar to tuning fork resonance). Based on the magnetic resonant coupling, a resonant magnetic field space is formed between the receiving coil and the transmitting coil, which typically covers a diameter range of 30-50cm.

[0093] Step S303: Obtain the induced current generated by the receiving coil in the resonant magnetic field space, use the induced current to charge the scanning device, and record the charging data.

[0094] In some embodiments of this application, within this resonant magnetic field space, the receiving coil generates a high induced electromotive force due to strong electromagnetic induction, thereby forming an induced current. During operation, by employing magnetic resonance technology, the energy transfer efficiency of the scanning device can still be maintained at 50%-80% even when the distance between the scanning device and the wireless charging device reaches 10-50cm. This energy transfer efficiency includes the overall system efficiency formed by the efficiency of the transmitting circuit, the coil coupling efficiency, and the receiving circuit.

[0095] After determining the induced current, the scanning device converts it into direct current (DC) through a rectifier and voltage regulator, thereby charging the scanning device. The scanning device includes a reader / writer. By detecting changes in the reader / writer's communication status, a counting logic is triggered, recording charging data in the scanning device's memory. This charging data can include the number of charging attempts, charging time, charging status, charging capacity, and charging power. The number of charging attempts is a historical cumulative value; it is automatically incremented and updated in the memory each time the device enters a charging state. The memory can be non-volatile (such as EEPROM or Flash), ensuring that the recorded data is not lost after power failure and extending the data storage time.

[0096] Step S304: Send charging data to the designated device via the dock.

[0097] In some embodiments of this application, the scanning device and the designated device may belong to the same device type; for example, both the scanning device and the designated device may be a digital dental impression instrument. Alternatively, the scanning device and the designated device may not belong to the same device type; for example, the scanning device may be a digital dental impression instrument, and the designated device may be a computer. The scanning device can transmit charging data to the base via a communication protocol (such as a dedicated protocol for magnetic resonance imaging or Bluetooth), and the base can transmit the charging data to the designated device via wired or wireless transmission technology.

[0098] In other embodiments of this application, the base may have a charging function. Both the scanning device and the base are equipped with NFC chips, enabling wireless charging via the NFC chips. Specifically, the NFC coil of the base generates an alternating magnetic field. When the NFC coil of the scanning device enters this alternating magnetic field (i.e., a 13.56MHz radio frequency field), it acquires the induced alternating current generated in the alternating magnetic field of the NFC coil of the base. The scanning device converts the induced alternating current into stable direct current through rectification, filtering, and voltage regulation circuits, thereby using the direct current to charge the scanning device and recording the charging data.

[0099] Wireless charging and communication control can be achieved through a single hardware design (such as an NFC chip), eliminating the need for additional charging devices. The core of using an NFC chip for wireless charging lies in reusing a 13.56MHz radio frequency field to collaboratively complete power transfer and data communication.

[0100] The charging process follows the NFC Forum's Wireless Charging (WLC) specification. The scanning device and the charging dock exchange control data via an NFC communication link. The scanning device actively reports its voltage and current requirements and status (such as battery level and temperature) to the dock, which then dynamically adjusts its output power accordingly, achieving safe, efficient, and precise charging. Energy transfer and data communication share the same 13.56MHz carrier wave, alternating through a precise "time-slice" mechanism. The system dedicates the vast majority of its time to efficient energy transfer, inserting data communication packets only during extremely short intervals, thus ensuring that both operate in parallel on the same physical channel without interference.

[0101] Through the above embodiments, pairing with the base using near-field communication technology improves the convenience, accuracy, and stability of pairing. When the scanning device enters the alternating magnetic field generated by the wireless charging device, if the first frequency generated by the receiving coil of the scanning device matches the second frequency generated by the transmitting coil of the wireless charging device, it indicates that the receiving coil and the transmitting coil have entered a magnetic resonance coupling state, generating a resonant magnetic field space and a stable induced current within it. The scanning device can then use this induced current to charge itself, achieving contactless charging and enabling simultaneous use and charging, thus improving charging efficiency. The scanning device records charging data and transmits it to the designated device via the base, thereby improving data transmission efficiency. This also enhances the data processing efficiency of the designated device in handling charging data, enabling timely and effective management of the scanning device.

[0102] In some embodiments of this application, in addition to sending charging data through the base, the scanning device also sends all the data recorded in the memory of the scanning device, as well as the device data of the scanning device body, the data of the scanning head body, etc.

[0103] In one example, the scanning device includes a pluggable scan head that can record scan data, the number of times the scan head is plugged in and out, and the number of times the scan head is used while the scan head is performing a scanning job. The scanning device can then transmit the scan data, the number of times the scan head is plugged in and out, and the number of times the scan head is used to a designated device via a base.

[0104] In one example, when the scanning device and the designated device are of the same type, suppose that during the process of performing an oral scan on a designated user, the scanning device is changed from clinic A to clinic B for some reason. In order to avoid repeated scanning of the designated user, the relevant data (such as scan data) of the scanning device can be transmitted to the designated device through the base. This allows the designated device to continue scanning the designated user based on the known relevant data, which can improve the user's work efficiency and the efficiency of device management.

[0105] In addition, if the designated device is a new scanning device, after the scanning device and the base are paired, the parameter configuration of the scanning device can be sent to the designated device (i.e., the new scanning device) through the base, so that the device deployment or status restoration can be completed quickly, reducing operation and maintenance costs.

[0106] In another example, when the scanning device and the designated device are not of the same type, the scanning device can send relevant data about its body and scanning head to the designated device via the dock. This allows the designated device to maintain the scanning device or control it to perform corresponding operations based on the data. Additionally, after pairing with the dock, the scanning device can also use the software program within the designated device to perform scanning tasks.

[0107] The scanning device includes a pluggable scanning head. The scanning device can acquire the number of times the scanning head has been used and the number of times it has been plugged in and out, and send the corresponding serial number, usage count, and plug-in / out count of the scanning head to a designated device via a base. The number of times the scanning head has been used and the number of times it has been plugged in and out can be recorded in the scanning head's own memory. The scanning device can read the usage count and plug-in / out count from the scanning head's own memory and record it in its own memory, which can speed up data storage efficiency and reduce data loss during data transmission. Furthermore, to reduce the size of the scanning head itself, the number of times the scanning head has been used and the number of times it has been plugged in and out can be directly stored in the scanning device's memory. Since the scanning device's memory has the property of not easily losing data when power is off, the following describes the process of recording the number of times the scanning head has been used and the number of times it has been plugged in and out, taking the direct storage of the number of times the scanning head has been used and the number of times it has been plugged in and out into the scanning device's memory as an example. Figure 6 Describe it.

[0108] Figure 6 This is a flowchart of the data transmission method provided in an embodiment of this application. For example... Figure 6 As shown, the steps include the following.

[0109] Step S601: In response to the insertion and removal operation of the scanning head, record the first operation number corresponding to the insertion and removal operation.

[0110] In some embodiments of this application, an NFC chip is provided inside the scanning head. When the NFC chip of the scanning head enters the radio frequency field of the reader / writer of the scanning device, it is determined that the scanning device has sensed the NFC chip of the scanning head. Upon sensing the NFC chip of the scanning head, the scanning device establishes a connection between the NFC chip of the scanning head and the scanning device, determining that the scanning head is in an inserted state. It is understood that when the scanning head is in the inserted state, the scanning head and the scanning device can form a single unit.

[0111] If the scanning device no longer senses the NFC chip on the scanning head within a preset time, it is determined that the NFC chip on the scanning head has left the radio frequency field of the reader / writer of the scanning device, causing a communication interruption, and thus the scanning head is determined to be in the unplugged state. It is understandable that when the scanning head is in the unplugged state, the scanning head and the scanning device are two separate, independent devices.

[0112] The scanning device continuously monitors the insertion and removal status of the scanning head to identify whether there is an insertion or removal action. If the scanning head's status changes from the insertion state to the removal state, a counting logic is triggered. The detection of the removal state is the trigger point for incrementing the count, and it is recorded as one insertion or removal operation.

[0113] When the scanning device determines that a plug-in / plug-out operation has occurred, it counts the plug-in / plug-out operations in response to the operation, generating a first operation count. It can be understood that the first operation count corresponds to at least one plug-in / plug-out operation before the memory is updated.

[0114] By recording the first number of insertion and removal operations, the scanning accuracy of the scanning head can be avoided from being affected by using the scanning head too many times.

[0115] Step S602: In response to the operation of using the scanning head, record the number of second operations corresponding to the operation of using the head.

[0116] In some embodiments of this application, the number of times the scanning head is used is determined based on the number of times a scanning process is completed. Each complete scanning process generates one usage operation, thereby recording the second operation count. In one example, assuming that a complete scanning process is performed after the scanning head is in the insertion state, it is determined that one usage operation is generated, and the second operation count is recorded as one. A complete scanning process may include the process from starting the scan to finally generating the scanned image. It is understood that the second operation count corresponds to at least one usage operation before updating the memory.

[0117] By recording the number of second operations corresponding to each operation, users can accurately know the status of the scanning head, which facilitates the maintenance of the scanning head.

[0118] Step S603: Based on the serial number corresponding to the scanning head, query the storage area that matches the serial number in multiple storage areas as the target storage area.

[0119] In some embodiments of this application, the scanning head has a limited lifespan, and the scanning device can be matched with multiple scanning heads, allowing the scanning device to complete subsequent scanning operations by replacing the scanning heads. When a scanning head is inserted into the scanning device, the scanning device can obtain the serial number corresponding to the inserted scanning head, query the storage area corresponding to that serial number from multiple storage areas in the memory, and if no storage area corresponding to that serial number is found, then a storage area is set in the scanning device's memory for the scanning head corresponding to that serial number. The serial number corresponding to each scanning head is unique.

[0120] In one example, the scanning device obtains the serial number AAA corresponding to the inserted scanning device. If no storage area with the identifier AAA is found in the memory, a storage area is set in the memory of the scanning device, and the identifier corresponding to the storage area can be AAA.

[0121] In some embodiments of this application, when a storage area corresponding to the serial number already exists, when the scanning device determines that a first operation count and / or a second operation count has been generated, it queries the storage area corresponding to the serial number in multiple storage areas of the memory based on the serial number corresponding to the scanning head. For ease of distinction, the storage area corresponding to the serial number is taken as the target storage area.

[0122] Step S604: Update the number of insertions and removals in the target storage area using the first number of operations, and update the number of uses in the target storage area using the second number of operations.

[0123] In some embodiments of this application, when the scanning device determines that a first number of operations has been generated, it updates the number of insertions and removals in the target storage area using the first number of operations, thereby recording all the insertions and removals of the scanning head in the target storage area.

[0124] When the scanning device determines that a second operation has occurred, it updates the usage count in the target storage area using the second operation count, thereby recording the total usage count of the scanning head in the target storage area.

[0125] Through the above embodiments, the number of times the scanning head is used and inserted / removed is accurately recorded, providing a basis for subsequent scanning head maintenance. Furthermore, recording the number of uses and insertion / removal counts separately avoids misjudgments caused by relying on a single record. For example, when the scanning head is inserted but a complete scanning process has not yet occurred, it avoids determining the actual usage of the scanning head solely based on the recorded number of insertions / removals, thus preventing recording errors. After the scanning device records the number of insertions / removals and uses of the scanning head, the data recorded in the memory can be read and transmitted wirelessly to the base station, so that the base station can send the insertion / removal counts and usage counts to a designated device.
