Description

Technical Field

[0001] This application relates to the field of ultrasound diagnostic technology in wireless communication, and more specifically, to a method and system for automatic connection and startup of ultrasound equipment based on near-field communication triggering. Background Technology

[0002] Handheld ultrasound devices are increasingly used in clinical diagnosis due to their portability. Wireless probes and mobile terminals typically transmit ultrasound image data and commands via a wireless network connection. However, the current pairing process is cumbersome, impacting user experience and diagnostic efficiency.

[0003] Currently, there are two main pairing methods: one is Bluetooth-assisted pairing, where users need to turn on Bluetooth to pair, obtain the probe's wireless network information, and then manually join the network. This process is cumbersome, usually requiring 5-7 steps and taking a long time. The other is QR code scanning pairing, where users need to open the application and scan the QR code on the probe. This method is relatively simple, but the QR code label is easily worn or damaged, and the recognition success rate drops significantly in poor lighting conditions.

[0004] Both of these methods require relatively complex user interaction before the scan begins. In time-sensitive medical scenarios such as ambulances, emergency rooms, and bedside visits, cumbersome matching processes can delay diagnosis. Summary of the Invention

[0005] This application aims to solve the above problems by providing a method and system for automatic connection and startup of ultrasound equipment based on near-field communication triggering, which realizes an automated connection and startup process of "touch and play" through near-field communication technology.

[0006] In a first aspect, this application provides a method for automatic connection and startup of an ultrasonic device based on near-field communication triggering, comprising the following steps: In response to a near-field communication touch operation between the mobile terminal and the wireless probe, an application matching the wireless probe is automatically launched on the mobile terminal. The wireless connection information of the wireless probe is transmitted to the application through the near-field communication. Based on the wireless connection information, the application automatically initiates a request to establish a wireless local area network connection with the wireless probe; In response to the mobile terminal joining the wireless local area network, the application obtains the device characteristic information of the wireless probe through the wireless local area network; Based on the device feature information, scanning parameters are automatically determined and sent to trigger the wireless probe to start acquiring ultrasound image data and transmitting ultrasound image data in real time based on the scanning parameters.

[0007] Optionally, automatically triggering the launch of an application matching the wireless probe on the mobile terminal includes: At the operating system level of the mobile terminal, the near-field communication touch operation is associated with the application's launch event and registered. When the near-field communication tag is sensed, the operating system directly launches the application, or pushes the application's launch window to the display interface, and launches the application after receiving a confirmation launch command.

[0008] Optionally, the application automatically initiates a request to establish a wireless local area network connection with the wireless probe based on the wireless connection information, including: the application calls the system network interface of the mobile terminal and uses the network name in the wireless connection information to automatically initiate a WiFi connection request.

[0009] Optionally, in response to the mobile terminal joining the wireless local area network, the application obtains the device characteristic information of the wireless probe through the wireless local area network, including: after the wireless probe detects that the mobile terminal has joined the wireless local area network, it automatically connects to the application and sends the device characteristic information to the application.

[0010] Optionally, the step of automatically determining and issuing scanning parameters based on the device feature information includes: The application obtains the user information of the currently logged-in user; combines the device feature information and the user information to determine the scanning parameters that match the user and the wireless probe, and sends them to the wireless probe.

[0011] Optionally, the device feature information includes at least one of probe type, probe serial number, firmware version number, and hardware configuration information.

[0012] Optionally, the method further includes: the mobile terminal obtaining inspection information through near-field communication touch operation or through interaction with the user; and based on the inspection information, determining and automatically triggering the launch of the application matching the wireless probe.

[0013] Secondly, this application provides an automatic connection and startup method for ultrasound equipment based on near-field communication triggering, applied to a mobile terminal, including the following steps: The wireless connection information of the wireless probe can be obtained by touching and operating the near-field communication tag on the wireless probe. In response to the sensing of the near-field communication tag, an application matching the wireless probe is automatically launched. Based on the wireless connection information, the application automatically initiates a request to establish a wireless local area network connection with the wireless probe; In response to the mobile terminal joining the wireless local area network, the application obtains device characteristic information sent by the wireless probe; Based on the acquired device feature information, scanning parameters are determined and issued to trigger the wireless probe to start acquiring ultrasound image data.

[0014] Thirdly, this application provides an automatic connection and start-up method for ultrasound equipment based on near-field communication triggering, applied to a wireless probe. The wireless probe is equipped with a near-field communication tag, which pre-stores the wireless connection information of the wireless probe. The method includes the following steps: In response to a touch operation by a mobile terminal via near-field communication, a communication connection is established with the mobile terminal; After detecting that the mobile terminal has joined the wireless local area network, the device connects to the application and sends device characteristic information to the application. The system receives scanning parameters from the application based on the device's feature information; it initiates ultrasound image data acquisition according to the scanning parameters and transmits the ultrasound image data to the application in real time.

[0015] Fourthly, this application provides an automatic connection and start-up system for ultrasonic equipment based on near-field communication triggering, comprising: A wireless probe with a near-field communication tag pre-stored in the wireless connection information of the wireless probe; A mobile terminal, which has an application installed that matches the wireless probe and has registered sensing events for the near-field communication tag; When the mobile terminal makes a near-field communication contact with the wireless probe, the mobile terminal senses the near-field communication tag, automatically triggers the launch of the application, and transmits the wireless connection information to the application. The application is used to automatically initiate a request to establish a wireless local area network connection with the wireless probe based on the wireless connection information; in response to the mobile terminal successfully connecting to the wireless local area network, it obtains the device characteristic information of the wireless probe; and automatically determines and sends scanning parameters based on the device characteristic information. The wireless probe is used to automatically connect to the application after detecting that the mobile terminal has successfully connected to the wireless local area network, send the device feature information and ready status signal to the application, and receive scanning parameters issued by the application based on the device feature information, and automatically start ultrasound image data acquisition based on the scanning parameters and transmit it to the application in real time.

[0016] The technical solution provided in this application has at least the following advantages compared with related technologies: First, this application simplifies the traditional cumbersome multi-step operation into a smooth, touch-to-use process by setting a near-field communication tag on the wireless probe and storing wireless connection information. This significantly reduces the user's operational burden, significantly shortens the pairing time, and saves valuable time for doctors and patients.

[0017] Secondly, this application improves system reliability by ensuring that device feature information is acquired and scanning parameters are sent only after the communication link is fully established, thus avoiding data transmission failures caused by incomplete connection.

[0018] Third, by combining user information and device feature information to determine personalized scanning parameters, this application can automatically match the optimal parameter set according to the usage habits of different users and the hardware characteristics of different probes, reducing the parameter adjustment work for users each time they use the device and improving the user experience.

[0025] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0026] In one embodiment, reference Figure 1 and Figure 2 This invention provides an automatic connection and startup method for ultrasound equipment based on near-field communication (NFC) triggering. The ultrasound equipment includes a wireless probe and a mobile terminal. The wireless probe can be a convex array ultrasound probe, a linear array ultrasound probe, or a phased array ultrasound probe, or other medical device probes that need to communicate with the mobile terminal via a wireless network and receive scanning parameters to start operation. The wireless probe is equipped with a near-field communication tag (such as an NFC tag), which pre-writes the near-field communication identifier (such as an NFC identifier) ​​and wireless connection information (such as a wireless network name, SSID). The wireless probe internally includes: a wireless communication component (such as a WiFi module) for creating and broadcasting a wireless access point; a control component (such as a microcontroller (MCU) or embedded processor) for executing control logic at the probe end; and a transducer array and an ultrasound imaging component for transmitting and receiving ultrasound signals and generating ultrasound image data. The mobile terminal can be a smartphone, tablet, or other portable device with an application (such as a portable ultrasound app) installed to work with the wireless probe. The mobile terminal has near-field communication sensing capabilities and can register sensing events (pre-registered event handlers) for specific near-field communication identifiers in the operating system so that corresponding operations are automatically triggered when a near-field communication tag conforming to a preset format is sensed, such as launching an application.

[0027] This embodiment provides an automatic connection and startup method for ultrasound equipment based on near-field communication triggering, which mainly includes the following steps: Step S101: In response to a near-field communication touch operation between the mobile terminal and the wireless probe, the application matched with the wireless probe is automatically launched on the mobile terminal.

[0028] Specifically, when the wireless probe is powered on, its internal wireless communication component creates and broadcasts a wireless access point (WiFi hotspot). The mobile terminal has its NFC function enabled. When the user brings the mobile terminal close to the wireless probe, bringing the distance between them within the preset NFC effective communication distance (e.g., within 10 cm), the mobile terminal's NFC reader senses the probe's NFC tag. After the mobile terminal's operating system recognizes the NFC tag's identifier, it automatically launches the application associated with that tag according to the pre-registered event handlers.

[0029] In practice, users simply need to bring the NFC sensing area of ​​their mobile device close to the NFC tag marking on the wireless probe to trigger this step. For example, if a user holds a smartphone with the "Pocket Ultrasound APP" installed and brings it close to the NFC tag area on the back of the wireless probe, the system will automatically open the "Pocket Ultrasound APP" after the phone senses the NFC tag.

[0030] In some optional embodiments, the application matched with the wireless probe is automatically launched on the mobile terminal. Specifically, at the operating system level of the mobile terminal, the near-field communication touch operation is associated with the application launch event. When the near-field communication tag is sensed, the operating system directly launches the application, or pushes the application's launch window to the display interface, and launches the application after receiving a confirmation launch command.

[0031] In practice, the mobile terminal's operating system can be Android. Since the application has registered response events for a specific near-field communication tag format within the system during installation, the system can automatically launch the application without user intervention.

[0032] In practice, the mobile terminal's operating system can be iOS. Due to system security policy restrictions, a confirmation window will pop up on the display screen to launch the application, prompting the user "Do you want to open the application?" The user needs to click the "Confirm" button before the application will be launched.

[0033] Step S102: Transmit the wireless connection information of the wireless probe to the application via near-field communication.

[0034] Specifically, after the application is launched, it calls the mobile terminal's system WiFi management interface to automatically parse the wireless connection information read from the NFC tag.

[0035] Step S103: Based on the wireless connection information, the application automatically initiates a request to establish a wireless local area network connection with the wireless probe.

[0036] Specifically, the application can call the mobile terminal's system network interface, use the network name (SSID) in the wireless connection information, and automatically initiate a request to join the wireless access point (such as a WiFi connection), requesting to join the WiFi network with the name SSID. At this time, a network joining confirmation interface can be displayed on the mobile terminal. After the user clicks to confirm, the connection operation is performed, and the application is notified whether the joining was successful. If the feedback is successful, it means that the mobile terminal has joined the wireless local area network.

[0037] Step S104: In response to the mobile terminal joining the wireless local area network, the application obtains the device characteristic information of the wireless probe through the wireless local area network.

[0038] Specifically, the wireless probe can act as a TCP server listening on a designated port, while the mobile terminal acts as a client initiating a connection request. Once the connection is established, a communication connection based on the TCP / IP protocol is established between the mobile terminal and the wireless probe; this communication connection provides a reliable data transmission channel.

[0039] When a wireless probe detects a mobile terminal successfully joining a wireless local area network (such as a wireless access point), it can automatically connect to the application that initiated the connection request and send device characteristic information and a ready status signal to that application. Device characteristic information describes the hardware and firmware attributes of the wireless probe, including at least one of the following: probe type (e.g., convex array, linear array, phased array), probe serial number (unique identifier), firmware version number, and hardware configuration information (e.g., number of array elements, operating frequency range, sampling rate). Alternatively, it can send a ready status signal to the application, indicating that the probe is ready to communicate and receive commands. Upon receiving the ready status signal, the application sends a device characteristic information request to the wireless probe via the established wireless communication link, requesting to obtain the probe's device characteristic information. The wireless probe responds to this request by sending the device characteristic information to the application.

[0040] Step S105: Based on the device feature information, automatically determine and issue scanning parameters to trigger the wireless probe to start ultrasound image data acquisition and transmit ultrasound image data in real time based on the scanning parameters.

[0041] In one embodiment, the ready status signal indicates that the probe is ready to communicate and receive commands. After receiving the ready status signal, the application determines the scanning parameters based on the acquired device characteristic information and sends these parameters to the wireless probe via a wireless communication link. The wireless probe then initiates the scanning operation based on the received scanning parameters. Specifically, the application may store a default scanning parameter table corresponding to different probe types. For example: for a convex array probe: the default is an abdominal scanning mode with a depth of 20cm, a gain of 50dB, a focal position of 10cm, and a frequency of 3.5MHz. For a linear array probe (type="linear"): the default is a shallow scanning mode with a depth of 5cm, a gain of 60dB, a focal position of 2.5cm, and a frequency of 7.5MHz. For a phased array probe (type="phased"): the default is a cardiac scanning mode with a depth of 16cm, a gain of 55dB, a focal position of 8cm, and a frequency of 2.5MHz. That is, the system pre-configures the corresponding scanning parameters for each type of probe. Scanning parameters are a set of parameters that control the operating mode of the wireless probe. These parameters may include at least one of the following: scanning mode (B-mode, M-mode, color Doppler mode, etc.), depth (scanning range, in centimeters), gain (signal amplification factor, in decibels), focal position (depth position of the focal point), and frequency (ultrasonic transmission frequency, in megahertz). The probe's control unit parses the scanning parameter fields and configures the transducer array's transmit / receive circuit parameters. For example, it adjusts the center frequency of the transmitted pulse based on the issued frequency parameter, adjusts the sampling rate of the received signal based on the depth parameter, and adjusts the amplification factor of the amplifier circuit based on the gain parameter. After configuration, the probe begins ultrasonic scanning, acquiring ultrasonic image data and transmitting the data in real time to a mobile terminal for display and / or processing. Specifically, this data may be transmitted to a mobile terminal application for display and / or processing.

[0042] In one embodiment, the application can further configure personalized parameters by combining the user information of the currently logged-in user. Specifically, the application obtains the user information of the currently logged-in user (such as username, employee ID, etc.), combines the device feature information and user information, retrieves personalized scanning parameters matching the user and the probe from a local database or cloud server, and sends them to the wireless probe. For example, if user A is accustomed to setting the gain to 45dB and the depth to 18cm when using a convex array probe for abdominal scanning, the application's personalized parameter set will record this preference and automatically recall it the next time it is used.

[0043] In one embodiment, the touch connection and information exchange between the wireless probe and the mobile terminal can be completed in one step through near-field communication touch operation.

[0044] Specifically, the moment the mobile terminal physically touches (or is within a very close sensing distance of) the NFC tag on the wireless probe, the terminal device completes the exchange of all the following information and the generation of commands: Detection and identification: The NFC reader of the mobile terminal detects the NFC tag on the probe and identifies that it conforms to the preset format.

[0045] Data reading: The mobile terminal reads all the pre-stored information from the tag, including but not limited to wireless connection information (such as WiFi SSID), probe identification information (such as model and serial number), and possible initial configuration parameters.

[0046] Event Trigger: The operating system automatically triggers the launch of the application (i.e., the ultrasound APP) that matches the label according to preset rules.

[0047] Data transfer: The operating system will read all the data as a data packet and transfer it completely to the newly launched APP, without the APP needing to perform any additional queries or interactions.

[0048] In one embodiment, the method further includes: the mobile terminal obtaining the information to be inspected through near-field communication touch operation or through interaction with the user; and based on the information to be inspected, determining and automatically triggering the launch of an application that matches the wireless probe.

[0049] Specifically, the NFC tag on the wireless probe not only stores network connection information, but can also further store information to be inspected.

[0050] For example: a heart probe: its NFC tag data may include "target_organ": "heart". An abdominal probe: its NFC tag data may include "target_organ": "liver". When a user touches their phone with the probe, the phone not only reads the Wi-Fi information but also the aforementioned "information to be checked". In this way, the app knows the probe's purpose upon startup.

[0051] Alternatively, information can be obtained through user interaction. Before or after touching the probe, the app can provide an interface for the user to manually input or select "examination information." For example, multiple independent apps such as "Cardiac Ultrasound Expert," "Abdominal Ultrasound Assistant," and "Obstetrics and Gynecology Ultrasound" may be installed on the mobile device. The doctor picks up an abdominal probe and touches it to the phone. The phone reads the NFC tag and finds "target_organ": "liver." Based on this information, the system automatically launches the "Abdominal Ultrasound Assistant" app without launching other unrelated apps. This avoids the user manually searching for and selecting the correct app among multiple applications.

[0052] Alternatively, a single application with multiple modules can be installed on the mobile terminal. This means the mobile terminal only has a comprehensive app called "All-in-One Ultrasound," but it contains multiple functional modules such as "Heart," "Abdominal," "Obstetrics and Gynecology," and "Vascular." When the app receives the "Obstetrics and Gynecology" information input by the user, and the probe is successfully connected, the app automatically switches to the "Obstetrics and Gynecology" module and loads the corresponding operation interface. Preferably, preset parameters (such as convex array probe, low frequency, high penetration) can also be loaded, allowing the user to start the examination directly without needing to determine and issue scanning parameters based on device characteristics. The user simply picks up a heart probe and touches it to the phone, or the phone reads the heart probe's NFC tag, discovering "probe_type": "phased_array" and "target_organ": "heart." Based on this information, the app automatically switches to the "Heart" module and loads the phased array probe's specific parameters (such as small field of view, high frame rate, color Doppler), requiring no user intervention.

[0053] The information to be examined includes at least one of the following: patient identity information, site to be examined, examination items, and examination scenario type. The scanning parameters can be automatically adjusted and generated by the application based on at least one of the information to be examined.

[0054] One embodiment provides an automatic connection and startup method for ultrasound equipment based on near-field communication triggering. This method is applied to the mobile terminal side. (Refer to...) Figure 3 The specific implementation steps are as follows.

[0055] Step S201: Obtain the wireless connection information of the wireless probe by touching the near-field communication tag on the near-field communication sensor.

[0056] The mobile terminal's operating system registers near-field communication (NFC) sensing events corresponding to the wireless probe's NFC tag. When the user brings the mobile terminal close to the wireless probe, the mobile terminal senses the NFC tag on the wireless probe via its NFC sensing module. The NFC tag can be a passive RFID tag, using a tag chip compliant with the ISO / IEC 14443 standard, capable of storing no more than 1KB of data; its operating frequency can be 13.56MHz, and the communication distance is typically within 10 centimeters. The NFC tag pre-stores the wireless probe's wireless connection information, including the network name (SSID). The mobile terminal reads and parses this information.

[0057] Step S202: In response to the sensing of a near-field communication tag, an application matching the wireless probe is automatically launched.

[0058] The mobile device has an application (such as a portable ultrasound app) installed to work with the wireless probe. When a registered near-field communication (NFC) sensing event is triggered on the mobile device, the application is launched. Specifically: when the mobile device is running Android, the NFC tag's sensing event registration mechanism automatically launches the application without any user intervention. When the mobile device is running iOS, a confirmation window will pop up, displaying a "Open?" prompt; the user must click the confirmation button for the application to launch.

[0059] In step S203, the application automatically initiates a request to establish a wireless local area network connection with the wireless probe based on the wireless connection information.

[0060] After the application is launched, it receives the wireless connection information read from the NFC tag. Based on this information, the application calls the mobile terminal's system WiFi management interface to initiate a join request to the wireless access point of the wireless probe. During this process, a network join confirmation interface will be displayed on the mobile terminal. After the user clicks to confirm, the join operation is completed. The mobile terminal successfully joins the wireless access point created by the wireless probe through the wireless network, thereby establishing a wireless communication link with the wireless probe.

[0061] In step S204, in response to the mobile terminal joining the wireless local area network, the application obtains the device characteristic information sent by the wireless probe.

[0062] After the wireless communication link is established, the wireless probe monitors the mobile terminal and detects that it has successfully joined the network. It automatically connects to the application and the application automatically sends its device characteristic information and ready status signal. At this time, the application can directly obtain the device characteristic information of the wireless probe.

[0063] Alternatively, after the wireless communication link is established, the wireless probe monitors that the mobile terminal has successfully joined the network and automatically sends a ready status signal to the application. The application receives this ready status signal. This signal indicates that the wireless probe is ready to communicate and receive commands. In response to the received ready status signal, the application automatically sends a device characteristic information request to the wireless probe. In response to this request, the wireless probe sends its device characteristic information to the application.

[0064] Step S205: Based on the acquired device feature information, determine and issue scanning parameters to trigger the wireless probe to start acquiring ultrasound image data.

[0065] The application stores scanning parameters that match device characteristic information, such as default scanning parameter tables for different probe types, allowing direct matching of default parameters based on probe type. In response to the received readiness status signal from the wireless probe, the application automatically sends out the determined scanning parameters and triggers the wireless probe to acquire ultrasound image data. Furthermore, to provide a more personalized user experience, the application can also obtain the currently logged-in user's information. Users typically log into their personal accounts before using the application, allowing the application to access the user's identity information, historical scanning records, and personal preference settings. Combining device characteristic information and user information, the application retrieves a personalized set of scanning parameters matching the user and the probe from a local database or cloud server, using these as the scanning parameters. Upon receiving the scanning parameters, the wireless probe initiates ultrasound image data acquisition, and the mobile terminal is also used to receive the acquired ultrasound image data.

[0066] One embodiment provides an automatic connection and startup method for ultrasound equipment based on near-field communication triggering. This method is applied to the wireless probe side, where a near-field communication tag is installed, and the tag pre-stores the wireless connection information of the wireless probe; (See reference...) Figure 4 The specific implementation steps are as follows.

[0067] Step S301: In response to the mobile terminal's touch operation via near-field communication, a communication connection is established with the mobile terminal.

[0068] After the wireless probe is powered on, its internal wireless communication component (such as a WiFi module) creates and broadcasts a wireless access point (WiFi hotspot). The connection information (SSID) of this wireless access point is pre-stored in the wireless probe's NFC tag. This information is written to the wireless probe's NFC tag during manufacturing or configured and written via an application during the user's first use. When a mobile terminal senses the NFC tag on the wireless probe and obtains connection information via NFC, it initiates a join request to the wireless access point created by the probe. The hotspot service program running in the wireless probe's communication component continuously monitors the terminal connection status in the wireless access point. When a new terminal device is detected to have successfully associated and obtained an IP address, the mobile terminal is considered to have successfully joined.

[0069] Step S302: After monitoring that the mobile terminal has joined the wireless local area network, connect to the application and send device characteristic information to the application.

[0070] Once the wireless probe confirms that the mobile terminal has successfully joined the wireless local area network, it automatically connects to the application and sends device characteristic information and a readiness status signal to the application. The readiness status signal indicates that the connection is complete and the wireless probe is ready to receive commands and parameters.

[0071] Step S303: Receive scanning parameters from the application based on device feature information, initiate ultrasound image data acquisition according to the scanning parameters, and transmit ultrasound image data to the application in real time.

[0072] The wireless probe receives scanning parameters from the application based on device characteristic information and initiates ultrasound image data acquisition accordingly. Scanning parameters may include scanning mode, depth, gain, focal position, frequency, etc. Specifically, the probe's control unit (such as a microcontroller) parses the scanning parameter fields and configures the transducer array's transmit / receive circuit parameters. For example, it adjusts the center frequency of the transmitted pulse based on the transmitted frequency parameter, adjusts the sampling rate of the received signal based on the depth parameter, and adjusts the amplification factor of the amplifier circuit based on the gain parameter. After configuration, the wireless probe begins ultrasound scanning, generates ultrasound image data, and transmits the ultrasound image data to the application in real time.

[0073] One embodiment provides a mobile terminal, see reference. Figure 5 The mobile terminal includes the following modules: Storage module 401 is used to store applications (such as a handheld ultrasound APP) and related data.

[0074] The NFC sensing module 402 is used to read the wireless connection information (including the SSID) stored in the NFC tag on the near-field communication sensing wireless probe. The NFC sensing module uses an NFC reader chip that conforms to the ISO / IEC 14443 standard.

[0075] The processing module 403 is used to trigger the launch of the application stored in the storage module after the NFC sensing module senses the NFC tag. The processing module 403 is configured to: automatically launch the application directly through the registered NFC sensing event when the mobile terminal's operating system is Android; and launch the application after the user confirms the launch of the iOS operating system.

[0076] The communication module 404 is used to establish a wireless link (such as a WiFi connection) with the wireless probe based on the wireless connection information obtained by the NFC sensing module. The communication module is also used to receive a ready status signal automatically sent by the wireless probe after the connection is successfully established, as well as to receive the device characteristic information of the wireless probe and send scanning parameters determined by the application based on the device characteristic information.

[0077] The specific method by which the application determines the scanning parameters based on device feature information is as follows: obtain the user information of the currently logged-in user, combine the device feature information and the user information, and retrieve the matching personalized scanning parameter set from the local database or cloud server.

[0078] One embodiment provides a wireless probe for use with a mobile terminal, see reference. Figure 6 The wireless probe includes: The probe housing 501 is used to house and protect the internal components.

[0079] A transducer array 502, disposed within the probe housing, is used to transmit ultrasonic signals and receive ultrasonic echo signals. The transducer array consists of multiple piezoelectric crystal units, and the number of array elements can be 64, 128, 192, etc., depending on the type of probe.

[0080] An ultrasonic imaging component 503, connected to the transducer array, is used to process the ultrasonic echo signal to obtain ultrasonic image data. The ultrasonic imaging component includes a transmitting circuit, a receiving circuit, a beam combiner, a signal processor, etc.

[0081] A near-field communication (NFC) tag 504 is disposed on the probe housing. The NFC tag pre-stores the wireless connection information (such as SSID) of the wireless probe, which is used to trigger the automatic launch of the application on the mobile terminal and obtain the wireless connection information when the tag is touched. The NFC tag uses a tag chip conforming to ISO / IEC 14443 or ISO / IEC 18092 standards. In this embodiment, the NFC tag can be a passive NFC tag, which obtains operating power from the mobile terminal through touch operation to transmit data, and does not require an internal power source.

[0082] The near-field communication tag may also pre-store the identity information or configuration information of the wireless probe, which is used to enable the mobile terminal to obtain this information through near-field communication in order to determine the application or functional module that matches the wireless probe.

[0083] The wireless communication component 505 is used to establish a wireless local area network connection with a mobile terminal based on wireless connection information. The wireless communication component can create a WiFi hotspot or establish a WiFi direct connection.

[0084] The control unit 506 is connected to both the ultrasound imaging unit and the wireless communication unit. The control unit is configured to: automatically connect to the application program after a successful wireless local area network connection is established; send device characteristic information and a readiness status signal to the application program via the wireless communication unit; and receive scanning parameters matching the device characteristic information sent by the application program in response to the readiness status signal. Based on the scanning parameters, control the transducer array and the ultrasound imaging unit to begin ultrasound image data acquisition, and transmit the ultrasound image data to the mobile terminal in real time via the wireless communication unit.

[0085] One embodiment provides an automatic connection and start-up system for ultrasound equipment based on near-field communication triggering. The system includes a wireless probe and a mobile terminal, which achieve automatic connection and start-up through near-field communication touch operation.

[0086] The wireless probe is a handheld wireless ultrasound probe equipped with a near-field communication tag (such as an NFC tag). This NFC tag pre-stores the wireless probe's wireless connection information, including the SSID of the wireless network. The NFC tag uses a passive tag chip compliant with the ISO / IEC 14443 standard, obtaining power from the mobile terminal through touch operation to transmit data; it does not require an internal power source.

[0087] The mobile terminal is a smartphone or tablet with an application installed that matches the wireless probe. Upon installation or initial runtime of the application, the mobile terminal registers sensing events for the near-field communication tag with the operating system.

[0088] When a mobile terminal touches a wireless probe during near-field communication (NFC) contact, the mobile terminal senses the NFC tag, automatically launches an application, and transmits wireless connection information to the application. The application then automatically initiates a request to establish a wireless local area network (WLAN) connection with the probe based on this information. Specifically, when the user brings the mobile terminal close to the probe for NFC contact, the mobile terminal's NFC sensing module senses the NFC tag on the probe and reads the wireless connection information stored in the tag. The mobile terminal's processing module automatically launches an application matched to the wireless probe based on the registered NFC sensing event. Subsequently, the wireless connection information obtained from the NFC tag is transmitted to the application. Based on this wireless connection information, the application calls the mobile terminal's system network interface and automatically initiates a request to establish a WiFi connection with the probe. At this time, a network joining confirmation interface can be displayed on the mobile terminal; the user clicks "confirm" to perform the joining operation. Upon successful joining of the WLAN created by the probe, a communication connection based on the TCP / IP protocol is established between the mobile terminal and the probe. After the mobile terminal successfully connects to the wireless local area network, it acquires the device characteristic information of the wireless probe; based on the device characteristic information, it automatically determines and sends out the scanning parameters.

[0089] The wireless probe acts as a TCP server, listening on a designated port. Upon detecting a successful wireless connection to the mobile terminal, it automatically connects to the application and sends device characteristic information and readiness status signals to the application. The application determines scanning parameters based on the acquired device characteristic information and sends them to the wireless probe. The wireless probe receives the scanning parameters from the application based on the device characteristic information and automatically begins acquiring ultrasound image data based on these parameters, transmitting the ultrasound image data to the application in real time via the wireless local area network.

[0090] In this embodiment, the wireless probe completes the entire process from device wake-up to ultrasonic scan initiation with a single touch operation, without requiring the user to perform additional Bluetooth pairing, QR code scanning, or manual parameter settings.

[0091] Traditionally, doctors need to open a mobile ultrasound app, wait for it to load, and then manually connect to the probe's Wi-Fi or scan the QR code on the probe, a process that takes 30-60 seconds. However, with the technology described in this application, doctors only need to bring their mobile device close to the probe; the app automatically launches and completes the connection and parameter configuration in just 5-10 seconds.

[0092] Traditional QR code scanning methods have an extremely low success rate in this environment. However, with the technical solution of this application, doctors do not need to precisely align the scan code; they only need to bring the mobile terminal close to the probe to complete the connection. This is unaffected by light or movement, greatly improving the reliability of use in mobile healthcare scenarios.

[0093] In other implementations, the wireless communication link between the mobile terminal and the wireless probe is not limited to WiFi. Other short-range wireless communication technologies, such as Bluetooth, ZigBee, and UWB (Ultra-Wideband), can also be used, as long as the bandwidth and real-time requirements for data transmission are met.

[0094] In other embodiments, the technical solution of this application is not limited to ultrasound probes. It can also be applied to other medical device probes that need to communicate with mobile terminals via wireless networks and receive scanning parameters to start operation, such as electrocardiogram probes, body temperature probes, and blood oxygen probes. The above probes can also store network connection information through NFC tags to achieve quick pairing and automatic start-up.

[0095] In other implementations, the personalized scanning parameter set can be stored not only in the mobile terminal's local database but also on a cloud server. The mobile terminal accesses the cloud server via the internet to download personalized parameters matching the current user and the current probe. Furthermore, user preferences and probe usage records can be synchronized to the cloud, enabling parameter sharing across multiple devices.
