[0052] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0053] One embodiment of the present invention provides a log transmission method. This method is applied to a continuous glucose monitoring device. According to... Figure 1 As shown, the continuous glucose monitoring device includes a transmitter 110 and a charging device 120. The transmitter 110 includes a first control unit 111 and a charging management unit 112. The TX pin of the first control unit 111 is connected to the TRX pin of the charging management unit 112.

The second charging interface includes a VBUS pin and a GND pin. The VIN pin of the first charging interface is connected to the VBUS pin of the second charging interface.

[0054] The first control unit 111 can control the charging management unit 112. In related technologies, the first control unit 111 controls the charging management unit 112 via I... 2 The charging management unit 112 is controlled via the C interface, but the first control unit 111 cannot be controlled via I. 2 The C interface controls the charging management unit to enable the data transmission channel between the TRX pin and the VIN pin.

[0055] The continuous glucose monitoring device enables the transmitter to be charged via a charging device through the adapter connection of the first charging interface and the second charging interface.

[0056] The first charging port and the second charging port can be magnetic charging ports. The first charging port is a magnetic female charging connector, and the second charging port is a magnetic male charging connector.

[0057] according to Figure 2 As shown, the log transmission method includes the following steps S210 to S240.

[0058] In step S210, the charging device receives the first instruction sent by the terminal device and sends the first instruction to the charging management unit.

[0059] The first instruction is used to instruct the data transmission channel between the TRX pin and the VIN pin of the charging management unit to be turned on.

[0060] In some embodiments, the charging device receives a first instruction sent by the terminal device via a first USB-to-TTL adapter and a data cable. One end of the first USB-to-TTL adapter is connected to the terminal device, and the other end is connected to the data cable, which is also connected to the charging device.

[0064] In step S220, the charging management unit opens the data transmission channel between the TRX pin of the charging management unit and the VIN pin of the charging management unit according to the first instruction.

[0065] A switch is provided between the TRX pin and the VIN pin of the charging management unit. The charging management unit controls the opening or closing of the data transmission channel between the TRX pin and the VIN pin by controlling the state of this switch.

[0066] When the data transmission channel between the TRX pin and the VIN pin is enabled, the charging management unit enters TRX mode. TRX mode indicates that the charging management unit can communicate with other devices to exchange data, thus enabling the charging management unit to perform not only charging functions but also data transmission functions.

[0067] In step S230, the first control unit sends log information to the TRX pin of the charging management unit via the TX pin.

[0068] The TRX pin of the charging management unit can both send and receive data. In this embodiment, the TRX pin is used to receive log information sent by the TX pin.

[0069] Log information consists of data and information related to blood glucose monitoring recorded by the continuous glucose monitoring device during operation. This log signal includes the device's operating status, blood glucose measurement results, user operation records, and abnormal event records.

[0070] In step S240, the charging management unit sends log information to the charging device through the data transmission channel between the TRX pin and the VIN pin, and the connected VIN pin and VBUS pin.

[0071] In step S250, the charging device sends the log information to the terminal device.

[0074] In this embodiment, step S250 specifically includes: the charging device sending log information to the data line, so that the data line transmits the log information to the second USB to TTL device, and the second USB to TTL device transmits the log information to the terminal device.

[0075] The second USB to TTL device includes a USB to TTL unit. One end of the USB to TTL unit is connected to the data cable, and the other end is connected to the terminal device.

[0076] The log information transmitted via the data line received by the USB to TTL unit is a TTL signal. The USB to TTL unit is used to convert the TTL signal corresponding to the log information into a USB signal, and then send the USB signal corresponding to the log information to the terminal device.

[0077] It should be noted that both the first USB to TTL device and the second USB to TTL device include a USB to TTL unit. This USB to TTL unit can convert USB signals to TTL signals or vice versa. The USB to TTL unit in the first USB to TTL device and the second USB to TTL device can be the same component or two separate components.

[0078] The log transmission method provided by this invention obtains log information by means of an external device, without the need to disassemble the continuous blood glucose monitoring device, which simplifies the log acquisition process, reduces operational complexity, avoids damage caused by device disassembly, and improves user experience.

[0079] In some embodiments, the method further includes: the charging device receiving a second instruction sent by the terminal device and sending the second instruction to the charging management unit; the charging management unit disconnecting the data transmission channel between the TRX pin and the VIN pin according to the second instruction. The second instruction is used to instruct the disconnection of the data transmission channel between the TRX pin and the VIN pin.

[0080] In some embodiments, the charging device receives a second instruction sent by the terminal device via a first USB-to-TTL converter and a data cable. That is, the second instruction is issued by the terminal device and transmitted sequentially to the charging device via the first USB-to-TTL converter and the data cable.

[0081] In some embodiments, the method further includes: when the charging management unit detects a charging voltage input to the VIN pin, the charging management unit disconnects the data transmission channel between the TRX pin and the VIN pin.

[0082] In this embodiment, when the Type-C female connector of the data cable is connected to an external terminal device, or when the Type-C female connector of the data cable is connected to an external charger, the charging management unit can detect that there is a charging voltage input on the VIN pin. At this time, the charging management unit automatically exits the TRX mode.

[0091] In step S408, the charging management unit sends log information to the charging device through the data transmission channel between the TRX pin and the VIN pin, and the connected VIN pin and VBUS pin.

[0092] It should be noted that during the transmission of log information, the connection between the first USB to TTL device and the data cable, and the connection between the first USB to TTL device and the terminal device are both disconnected. The data cable remains connected to the charging device. One end of the second USB to TTL device is connected to the data cable, and the other end of the second USB to TTL device is connected to the terminal device.

[0093] In step S409, the charging device sends log information to the data cable.

[0094] In step S410, the data cable transmits the log information to the second USB to TTL device.

[0095] In step S411, the second USB to TTL device transmits the log information to the terminal device.
