[0051] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way a limitation on the embodiments of the present specification, their applications, or uses.

[0052] It should be noted that like reference numerals and letters denote like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.

[0053] An 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 charging management unit 112 is provided with a first charging interface. The charging device 120 is provided with a second charging interface. The first charging interface includes a VIN pin and a GND pin. 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 the related art, the first control unit 111 controls the charging management unit 112 through an I 2 C interface, but the first control unit 111 cannot control the charging management unit through the I 2 C interface to enable the charging management unit to open the data transmission channel between the TRX pin and the VIN pin.

[0055] The continuous glucose monitoring device realizes charging the transmitter through the charging device by the adapter connection of the first charging interface and the second charging interface.

[0056] The first charging interface and the second charging interface can be magnetic charging interfaces. The first charging interface is a magnetic charging female head, and the second charging interface is a magnetic charging male head.

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

[0058] 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 indicate to turn on the data transmission channel between the TRX pin and the VIN pin of the charging management unit.

[0060] In some embodiments, the charging device receives the first instruction sent by the terminal device through the first USB to TTL device and the data cable. One end of the first USB to TTL device is connected to the terminal device, the other end of the first USB to TTL device is connected to the data cable, and the data cable is also connected to the charging device. That is, the first instruction is sent by the terminal device and is transmitted to the charging device through the first USB to TTL device and the data cable in sequence.

[0061] According to Figure 3 As shown, the first USB to TTL device includes a second control unit and a USB to TTL unit. One end of the data cable is connected to the second control unit, the second control unit is connected to the USB to TTL unit, and the USB to TTL unit is connected to the terminal device.

The USB to TTL unit is used to convert the USB signal corresponding to the first instruction into a TTL signal, and the second control unit is used to convert the TTL signal into a signal corresponding to the protocol recognizable by the charging management unit.

[0063] The data cable includes a TypeC male head. The TypeC male head of the data cable is connected to the TypeC female head of the charging device. The VBUS pin of the data cable is connected to the CMD pin of the second control unit, and the GND pin of the data cable is connected to the GND of the second control unit.

[0064] Step S220, the charging management unit turns on the data transmission channel between the TRX pin and the VIN pin of the charging management unit according to the first instruction.

[0065] A switch is arranged between the TRX pin and the VIN pin of the charging management unit. The charging management unit controls the on or off of the data transmission channel between the TRX pin and the VIN pin by controlling the state of the switch.

[0066] When the charging management unit enables the data transmission channel between the TRX pin and the VIN pin, the charging management unit enters the TRX mode. The TRX mode means that the charging management unit can communicate with other devices to achieve data exchange, so that the charging management unit can not only realize the charging function, but also realize the function of data transmission.

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

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

[0069] The log information is data and information related to blood glucose monitoring recorded during the operation of the continuous blood glucose monitoring device. The log signal includes the working state of the continuous blood glucose device, the blood glucose measurement result, the user operation record, and the abnormal event record.

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

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

One end of the second USB to TTL device is connected to the data line, and the other end of the second USB to TTL device is connected to the terminal device.

[0073] It should be noted that the connection between the first USB to TTL device and the data line and the connection between the first USB to TTL device and the terminal device are both in a disconnected state, and the data line remains connected to the charging device.

[0074] In this embodiment, step S250 specifically includes: the charging device sends the 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 line, and the other end of the USB to TTL unit is connected to the terminal device.

[0076] The log information transmitted by 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. The USB to TTL unit can either convert a USB signal into a TTL signal or convert a TTL signal into a USB signal. The USB to TTL units in the first USB to TTL device and the second USB to TTL device can be the same component or two components.

[0078] The log transmission method provided by the present invention obtains log information by means of an external device, without disassembling the continuous glucose monitoring device, simplifies the log acquisition process, reduces the operation complexity, avoids damage caused by device disassembly, and improves the user experience.

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

[0080] In some embodiments, the charging device receives the second instruction sent by the terminal device through the first USB to TTL device and the data line. That is, the second instruction is issued by the terminal device and is transmitted to the charging device through the first USB to TTL device and the data line in sequence.

[0081] In some embodiments, the method further includes: when the charging management unit detects that there is 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 head of the data line is connected to an external terminal device, or when the Type-C female head of the data line is connected to an external charger, the charging management unit can detect that there is a charging voltage input to the VIN pin. At this time, the charging management unit automatically exits the TRX mode.

[0085] Step S402: The USB-to-TTL unit in the first USB-to-TTL device converts the USB signal corresponding to the first instruction into a TTL signal, and the second control unit in the first USB-to-TTL device converts the TTL signal into a signal corresponding to the protocol recognizable by the charge management unit.

[0086] Step S403: The second control unit transmits the signal corresponding to the protocol recognizable by the charge management unit corresponding to the first instruction to the data line.

[0087] Step S404: The data line transmits the signal corresponding to the protocol recognizable by the charge management unit corresponding to the first instruction through the Type-C male head of the data line to the Type-C female head of the charging device.

[0088] Step S405: The charging device sends the signal corresponding to the protocol recognizable by the charge management unit corresponding to the first instruction to the charge management unit.

[0089] Step S406: The charge management unit opens the data transmission channel between the TRX pin and the VIN pin of the charge management unit according to the first instruction.

[0090] Step S407: The first control unit sends the log information to the TRX pin of the charge management unit through the TX pin.

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

[0092] It should be noted that when transmitting the log information, the connection between the first USB-to-TTL device and the data line and the connection between the first USB-to-TTL device and the terminal device are both in a disconnected state, the data line is kept connected to the charging device, one end of the second USB-to-TTL device is connected to the data line, and the other end of the second USB-to-TTL device is connected to the terminal device.

[0093] Step S409: The charging device sends the log information to the data line.

[0094] Step S410: The data line transmits the log information to the second USB-to-TTL device.

[0095] Step S411: The second USB-to-TTL device transmits the log information to the terminal device.

[0096] Step S412: When the charge management unit detects that there is a charging voltage input on the VIN pin, the charge management unit disconnects the data transmission channel between the TRX pin and the VIN pin to terminate the transmission of the log information.
