[0038] Among them, the VBUS bus power is the main power supply line, responsible for providing the required power. The VBUS bus is usually connected to the power management module, which is responsible for regulating and distributing power to ensure that the EIT equipment can obtain a stable power supply under different working conditions. The power management module also monitors the power input and output to ensure the stability and safety of the power supply.

[0039] Among them, the GND grounding wire is the reference potential, and the potential of all circuits is measured relative to this reference potential. The design of the GND grounding wire requires special attention to ensure that the grounding potential is stable and avoid ground loops and noise interference.

[0040] In one embodiment, the configuration channel module 30 includes a first configuration channel and a second configuration channel, and the first configuration channel and the second configuration channel are respectively connected to the fast charging negotiation module 40 .

[0041] Among them, Figure 2 The first configuration channel and the second configuration channel correspond to CC1 and CC2 respectively. The first configuration channel and the second configuration channel are used for communication and negotiation between the charging device and the charger. These two channels are usually used to transmit charging protocol information, such as charging voltage, current and other control signals. The fast charging negotiation module is responsible for parsing and processing control signals to ensure that the charging parameters can be correctly negotiated between the charging device and the charger, thereby achieving fast charging.

[0042] In one embodiment, the power management module 50 includes a Buck / boost converter and a low-voltage dropout linear regulator, the fast charging negotiation module 40 is connected to the Buck / boost converter, the Buck / boost converter is connected to the low-voltage dropout linear regulator, and the low-voltage dropout linear regulator is connected to the controller 60; the Buck / boost converter is used to adjust the input voltage to the required output voltage, and the low-voltage dropout linear regulator is used to stabilize the output voltage.

[0043] Among them, Buck / boost converter: This is a bidirectional DC-DC converter that can boost or buck the input voltage as needed to generate the required output voltage.

[0044] Among them, low dropout linear regulator (LDO): This regulator is used to provide a stable voltage at the output end, and can keep the output voltage stable even when the input voltage fluctuates or the load changes.

[0045] Among them, the power management module is responsible for power regulation, distribution and monitoring.

[0046] Specifically, the power management module works with the VBUS bus power supply, GND ground wire, and CC1 and CC2 configuration channels to ensure stable power supply in different working states. The power management module also monitors power input and output to ensure the stability and safety of the power supply.

[0048] Among them, in the first communication loop, the power line module 20, the configuration channel module 30, the fast charging negotiation module 40, the power management module 50, and the controller 60 are turned on, and other components do not work. At this time, only the fast charging function is completed.

[0049] Among them, in the second communication loop, the power line module 20, the fast charging negotiation module 40, the power management module 50, the controller 60, the analog front-end module 80, and the micro-control module 90 are turned on. At this time, the power line module 20, the fast charging negotiation module 40, and the power management module 50 form a stable voltage to support the controller 60, the analog front-end module 80, and the micro-control module 90 to work. The stable voltage at this time can be 5V or other values, which are not limited here. It should be noted that the USB module 70 and the configuration channel module 30 are not enabled in the second communication loop.

[0050] Among them, in the second communication loop, the power line module 20 is used to provide a channel for power transmission, and works with the analog front-end module 80 to ensure that power can be supplied normally while transmitting analog signals. The fast charging negotiation module 40 is responsible for charging parameters to achieve stable power supply; the power management module 50 monitors the entire charging process and ensures the stability and safety of the power supply during the transmission of analog signals; the controller 60 is responsible for coordinating the work of each module, including the operation of the AFE module 80 and the microcontroller module 90 in the analog signal transmission mode. The analog front-end module 80 is responsible for sending, processing and converting analog signals to ensure the accuracy and integrity of the signals. After the analog front-end module 80 converts the analog signal into a digital signal, it is transmitted to the microcontroller module 90 through the SPI interface. The microcontroller module 90 sends an analog signal to an external device to collect the signal, and then sends the collected signal to the analog front-end module 80. The analog front-end module 80 can convert the collected signal and send it to the controller 60.

[0051] Among them, in the third communication loop, the power line module 20, the fast charging negotiation module 40, the power management module 50, the controller 60, the USB module 70, the analog front-end module 80, and the micro-control module 90 are turned on. At this time, the power line module 20, the fast charging negotiation module 40, and the power management module 50 form a stable voltage to support the controller 60, the USB module 70, the analog front-end module 80, and the micro-control module 90 to work. The stable voltage at this time can be 5V or other values, which are not limited here. It should be noted that the configuration channel module 30 is not enabled in the second communication loop.

[0052] Among them, in the third communication loop, the power line module 20 is used to provide a channel for power transmission, and works with the analog front-end module 80 to ensure that power can be supplied normally while transmitting analog signals. The fast charging negotiation module 40 is responsible for charging parameters to achieve stable power supply; the power management module 50 monitors the entire charging process and ensures the stability and safety of the power supply during the transmission of analog signals; the controller 60 is responsible for coordinating the work of each module, including the operation of the USB module 70, the AFE module 80, and the microcontroller module 90 in the analog signal transmission mode. The analog front-end module 80 is responsible for sending, processing and converting analog signals to ensure the accuracy and integrity of the signals. After the analog front-end module 80 converts the analog signal into a digital signal, it is transmitted to the microcontroller module 90 through the SPI interface. The microcontroller module 90 sends an analog signal to an external device to collect the signal, and then sends the collected signal to the analog front-end module 80. The analog front-end module 80 can convert the collected signal and send it to the USB module 70.

[0053] The analog front-end module 80 can be directly connected to the USB 3.0 differential signal lines for transmitting analog signals. These signal lines were originally designed for high-speed digital data transmission, but are innovatively used as the transmission medium for analog signals here.

[0054] The USB module 70 is mainly used for the transmission of digital signals, but in this embodiment, part of its function is used to assist the transmission of analog signals. The USB 3.0 differential signal line is connected to the USB module 70 through the analog front-end module 80, so that the analog signal is converted into a digital signal and then transmitted to the USB module 70 through the SPI interface.

[0055] In one embodiment, the first communication circuit is used to achieve fast charging; the second communication circuit is used to send an analog signal, collect data from the target device, and transmit the collected first data to the controller 60; the third communication circuit is used to send the analog signal, collect data from the target device, and transmit the collected second data through the USB module 70.

[0056] In the first communication loop, the fast charging function is realized; in the second communication loop, the analog signal is collected and transmitted while maintaining the stability and safety of the power supply; in the third communication loop, the analog signal is converted into a digital signal, and the digital signal is transmitted through the USB module 70. Each loop has its own specific module combination and working mode, ensuring the flexibility and versatility of the device. The innovative use of the analog front-end module 80 enables the USB 3.0 differential signal line to be used for the transmission of analog signals, while the USB module 70 plays a role in the transmission of digital signals.

[0057] It should be noted that the above-mentioned charging communication connection device with a Type C interface can execute the charging communication connection method with a Type C interface provided in the embodiment of this application, and has the corresponding functional modules and beneficial effects of the execution method. For technical details not fully described in the embodiment of the charging communication connection device with a Type C interface, please refer to the charging communication connection method with a Type C interface provided in the embodiment of this application.

[0058] As another aspect of the embodiment of the present application, the embodiment of the present application provides a charging communication connection method with a Type C interface. Figure 3 As shown, Figure 3 It is a flow chart of a charging communication connection method with a Type C interface, which is applied to a charging communication connection device with a Type C interface, and the charging communication connection device with a Type C interface is located in a portable EIT device.

[0059] S10. Receive an insertion signal, where the insertion signal is used to instruct the charging communication connection device with the Type C interface to start a target working mode.

[0060] When a user inserts a charging cable or data cable of a Type C interface into the Type C interface of a portable EIT device, the charging communication connection device inside the device will immediately detect this physical action and generate an insertion signal. The insertion signal can be an electrical signal, which is triggered by the physical contact of the interface and transmitted to the identification unit of the device through the circuit.

[0061] Among them, the main function of the insertion signal is to notify the charging communication connection device that an external device (such as a charger, computer or other Type C compatible device) has been connected and some form of interaction may be required. Inserting this signal is a trigger to start the target working mode, which tells the device to prepare for the corresponding operation.

[0062] The target working mode refers to an operating mode selected and activated by the device according to the type of device inserted and user needs. These modes may include charging mode, data transmission mode, device configuration mode, etc. Each mode will have different power management strategies and communication protocols.

[0063] For example, if it is plugged into a charger, the device may start charging mode; if it is plugged into a computer, the device may start data transfer mode.

[0064] Among them, once the insertion signal is received and recognized, the controller in the charging communication connection device will switch to the corresponding target working mode according to the preset program or user's instructions. The controller will adjust the status of each module inside the device, such as the power cord module starts to supply power, the configuration channel module adjusts the interface configuration, and the fast charging negotiation module negotiates charging parameters with the charger. In the target working mode, the device will perform corresponding functions, such as charging the portable EIT device, exchanging data with external devices, or performing other communication tasks. For example, in the fast charging mode, the device may need to adjust the voltage and current parameters and negotiate the charging protocol with the connected device.

[0065] It can be seen that the charging communication connection device of the portable EIT device in this embodiment can automatically and efficiently respond to the connection of the external device without the user having to perform complicated operations, thereby improving the usability and functionality of the device.

[0066] S20: According to the target working mode, operate the charging communication connection device with the Type C interface to enable the portable EIT device to communicate with the target device.

[0067] After receiving the insertion signal and starting the target working mode, the charging communication connection device first needs to identify the specific working mode. This is usually done by the controller and microcontroller module in the device, which will determine which working mode is based on the characteristics of the insertion signal and the preset logic.

[0068] Once the target operating mode is identified, the various modules in the device will be configured according to the mode, which may include configuring the communication protocol (such as USB, Thunderbolt, etc.) to ensure the correct setting of the data channel.

[0069] During the initialization process, the devices may need to perform a handshake protocol to confirm the compatibility and data transmission capabilities of both devices.

[0070] For example: the power line module, if the working mode is charging, the power line module will prepare to transmit power; the configuration channel module will set the pins of the TypeC interface to support the required signal transmission, whether it is power supply, data transmission or other functions, the fast charging negotiation module communicates with the external charger to negotiate the best charging parameters to ensure fast and safe charging; if the working mode includes data transmission, the USB module will prepare to establish a data connection with the external device.

[0071] Among them, after the module configuration is completed, the charging communication connection device will start to establish a communication connection with the target device. This process may include the following steps: physical connection, ensuring that the physical connection of the TypeC interface is stable and provides a reliable path for data or power transmission; protocol handshake, handshake through a specific communication protocol (such as USB protocol) to confirm the connection and communication parameters between the two devices; data transmission preparation, if the working mode includes data transmission, the device will prepare the data transmission channel, which may involve the cooperation of the analog front-end module and the microcontroller module.

[0072] After the communication connection is established, the portable EIT device can exchange data or perform other communication operations with the target device. For example, if the working mode is charging, power will be transferred from the charger to the portable EIT device to charge its battery; if the working mode is data transmission, the portable EIT device can send or receive data, such as patient information, device settings, or tomographic imaging data.

[0073] It can be seen that the charging communication connection device of the EIT device in this embodiment not only provides a charging function, but also realizes efficient communication with external devices, thereby enhancing the flexibility and versatility of the device, and also provides users with a more convenient usage experience.

[0074] The method automatically starts the target working mode by receiving an insertion signal, eliminating the steps of manual setting and adjustment, making the use of the device more convenient and efficient; adopts a TypeC interface, which has wide compatibility and versatility and can be connected to a variety of devices, reducing dependence on specific adapters and improving the applicability of the device; charging and communication through the TypeC interface can provide stable power supply and data transmission, ensuring efficient communication between the portable EIT device and the target device.

[0075] In one embodiment, operating the charging communication connection device with a TypeC interface according to the target working mode includes: when the target working mode is the first working mode, performing fast charging; or, when the target working mode is the second working mode, sending an analog signal, collecting data from the target device, and transmitting the collected first data to a controller in the charging communication connection device with a TypeC interface; or, when the target working mode is the third working mode, sending an analog signal, collecting data from the target device, and transmitting the collected second data through a USB module in the charging communication connection device with a TypeC interface.

[0076] Among them, the first working mode is the fast charging mode, which is generally used to provide the maximum current and voltage to the target device in the shortest time to achieve fast charging. The charging communication connection device with a TypeC interface negotiates the optimal charging parameters with the target device through the power transmission protocol of the TypeC interface (such as USB Power Delivery). Adjust the output voltage and current according to the needs and battery status of the target device. During the fast charging process, the charging communication connection device with the TypeC interface monitors the temperature, current and voltage to prevent overheating or overload. If necessary, the charging communication connection device with the TypeC interface will automatically reduce the charging speed to protect the battery.

[0077] Among them, in the second working mode, the charging communication connection device with a TypeC interface is used to send analog signals to collect data. Specifically, analog signals can be generated according to the analog front-end module in the charging communication connection device with a TypeC interface, and these signals may be excitation signals for bioelectrical impedance tomography (EIT); the analog signals generate responses through the target device (which may be an EIT sensor or other medical monitoring device), and these responses are converted into first data; the collected first data is transmitted to the controller in the charging communication connection device. The controller is responsible for processing these data, which may include preliminary analysis, storage, or preparation of data to be sent to the main processor of the portable EIT device.

[0078] Among them, in the third working mode, analog signals are also sent for data collection, but unlike the second working mode, a transmission branch is added to the data transmission, that is, the collected data is transmitted to the USB and then transmitted to other devices through the USB module.

[0079] Specifically, the analog front-end module is the same as the second working mode, generating analog signals for data collection; the collected data is called the second data, which needs to be transmitted through the USB interface; the USB module transmits the collected second data through the TypeC interface. It involves converting analog signals into digital signals, which are then packaged and transmitted through the USB protocol; the USB module is responsible for establishing a connection with external devices (such as computers, data loggers or other medical devices) and reliably transmitting data.

[0080] It can be seen that in this embodiment, through the setting of these three working modes, the charging communication connection device can not only provide charging function for the portable EIT device, but also perform data collection and transmission tasks as needed, thereby improving the flexibility and versatility of the device. Each mode is targeted at different usage scenarios, ensuring the efficient operation of the device in different environments.
