[0049] Embodiments of the first aspect

[0050] The embodiments of the present application provide a portable electronic product with a memory, Figure 1 is a schematic diagram of an internal circuit of the portable electronic product 100 of the embodiments of the present application; as shown in the figure, the portable electronic product 100 includes a control manager 101, a data acquisition circuit 102 connected to the control manager 101, and a memory power supply circuit 103 connected to the control manager 101. As shown in the figure, Figure 1 The portable electronic product 100 further includes a memory 104 connected to the control manager 101, the memory power supply circuit 103, and a PC (Personal Computer) or a USB (Universal Serial BUS) host (in the case of being plugged in). Wherein, the control manager 101 controls the turn-on and turn-off of the data acquisition circuit 102 and / or the memory power supply circuit 103 according to the pre-set conditions, to switch the communication mode of the memory 104 of the portable electronic product 100. Figure 1 By using the above-mentioned portable electronic product 100 provided by the embodiments of the present application, the intelligent switching of the communication mode of the memory 104 can be realized without using a physical switch, not only improving the use convenience of the portable electronic product 100, but also reducing the waiting time of the memory 104 when switching the communication mode, and improving the use efficiency of the portable electronic product 100.

[0051]

[0052] ​In this embodiment, the memory 104 is exemplified as an SD card (Secure Digital Card). In some possible embodiments, the memory 104 may also be, for example, a mini SD card, a CF (Compact Flash) card, an MMC card (Multi-Media Card), etc. This application does not limit the scope of the application.

[0053] In existing portable electronic products with memory, different usage states require different data transfer rates. Generally, higher data transfer rates lead to increased power consumption, which is detrimental to the long battery life required by portable electronic products. Conversely, when the portable electronic product is kept in a low-power state, the data transfer rate of the memory is limited. Therefore, it is necessary to switch the communication method of the memory according to the different needs of the portable electronic product.

[0054] In the above embodiments, the communication methods of the memory 104 include a first communication mode and a second communication mode, wherein the transmission rate in the second communication mode is higher than that in the first communication mode. This application is not limited to this; the communication methods of the memory 104 may also include other communication modes, with different transmission rates in different communication modes, or the portable electronic product 100 performing different functions in different communication modes, so that the portable electronic device is suitable for different scenarios, etc.

[0055] For ease of explanation, this application uses two communication modes (first communication mode and second communication mode) with different transmission rates as examples.

[0056] According to the portable electronic product 100 provided in the embodiments of this application, the control manager 101 can realize intelligent switching of the memory 104 between the first communication mode and the second communication mode according to the preset conditions.

[0057] In the above embodiments, the first communication mode is, for example, a low-speed communication mode via a Serial Peripheral Interface (SPI), and the second communication mode is, for example, a high-speed communication mode via a Secure Digital Input and Output (SDIO) interface. The SDIO interface enables high-speed data transfer of the memory 104.

[0058] Figure 2 Is it like this? Figure 1 A schematic diagram of the internal circuitry of memory 104 is shown; as follows: Figure 2As shown, the memory 104 has different types of SPI communication ports 41 and SDIO communication ports 42. The control manager 101 can control the on and off of the data acquisition circuit 102 and / or the memory power supply circuit 103 according to preset conditions, so that the communication mode of the memory 104 of the portable electronic product 100 can be switched between a first communication mode and a second communication mode.

[0059] In some embodiments, the pre-defined conditions include at least one of the following:

[0060] Whether the portable electronic product 100 is connected to a PC or USB host 105;

[0061] Whether the communication protocol between the portable electronic product 100 and the PC or USB host 105 is valid.

[0062] For example, if the control manager 101 detects the insertion of a PC or USB host 105 and confirms that the communication protocol is valid, it controls the switching on and off of the data acquisition circuit 102 and / or the memory power supply circuit 103, switching the communication mode of the memory 104 to the second communication mode described above.

[0063] In the above embodiments, the portable electronic product 100 also has a USB interface circuit 110, which connects to the control manager 101 for connecting to a PC or a USB host 105. Figure 3 This is a schematic diagram of the USB interface circuit 110 of the portable electronic product 100 according to an embodiment of this application; the USB interface circuit 110 is capable of... Figure 1 The memory 104 of the portable electronic product 100 shown is connected to a PC or USB host 105, such as Figure 3 As shown, the USB interface circuit 110 has a port CN1, through which the portable electronic product 100 can be connected to a PC or USB host 105. The control manager 101 can switch the communication mode of the memory 104 according to whether the portable electronic product 100 is connected to the PC or USB host 105.

[0064] In some embodiments, such as Figure 1 As shown, the portable electronic product 100 also includes an access detection circuit 106, which is used to monitor whether the portable electronic product 100 is connected to a PC or USB host 105, such as... Figure 1 As shown, the access detection circuit 106 is connected to the control manager 101 and can monitor whether the portable electronic product 100 is connected to the PC or USB host 105. Figure 4 Is it like this? Figure 1 A schematic diagram of the detection circuit 106 connected in the internal circuit shown; as follows Figure 4As shown, the access detection circuit 106 has an access detection port 51, for example, when the input of the access detection port 51 is high, it indicates that the portable electronic product 100 is not connected to the PC or USB host 105, and when the input of the access detection port 51 is low, it indicates that the portable electronic product 100 is connected to the PC or USB host 105.

[0065] In the above embodiment, when the USB interface circuit 110 of the portable electronic product 100 is connected to the PC or USB host 105, the memory 104 can communicate data with the PC or USB host 105, or can only charge the portable electronic product through the PC or USB host 105, therefore, in order to more accurately determine the data transmission requirement of the portable electronic product 100, the control manager 101 can further determine whether the communication mode of the memory 104 needs to be switched according to whether the communication protocol is valid when the portable electronic product 100 is connected to the PC or USB host 105.

[0066] In the above embodiment, the communication protocol between the memory 104 and the PC or USB host 105 includes: SD protocol (Secure Digital Protocol), SPI protocol, SDIO protocol, etc.

[0067] In the embodiment of the present application, the memory 104 is taken as an example of an SD card, and for different types of memories, other communication protocols between the memory and the PC or USB host 105 are also included, which are not limited in the present application.

[0068] In the above embodiment, when the control manager 101 controls the turn-on and turn-off of the data acquisition circuit 102 and / or the memory power supply circuit 103 to perform the switching of the communication mode of the memory 104, the following determination is performed:

[0069] When the portable electronic product 100 is connected to the PC or USB host 105 and the communication protocol is valid, the control manager 101 controls the data acquisition circuit 102 to be turned off, and controls the memory power supply circuit 103 to be turned on, so as to switch the communication mode of the memory 104 to the second communication mode;

[0070] When the portable electronic product 100 is connected to the PC or USB host 105 but the communication protocol is invalid, or when the portable electronic product 100 is not connected to the PC or USB host 105, the control manager 101 controls the data acquisition circuit 102 to be turned on, and controls the memory power supply circuit 103 to be turned off, so as to switch the communication mode of the memory 104 to the first communication mode.

[0071] Based on the above conditions, in the second communication mode with higher transmission efficiency, the memory 104 needs to transmit data to the PC or USB host 105. At this time, in order to improve the efficiency of data transmission, the control manager 101 cuts off the data acquisition circuit 102 of the portable electronic product 100 and turns on the memory power supply circuit 103. This can turn off the data acquisition function of the portable electronic product 100, enabling it to transmit data to the PC or USB host 105 in the second communication mode, shortening the data transmission time, improving the data transmission efficiency, and thus enhancing the user experience of the portable electronic product 100.

[0072] In contrast, in the first communication mode with lower transmission efficiency, the memory 104 does not need to transmit data to the PC or USB host 105, but only needs to store the data acquired by the data acquisition circuit 102. Therefore, the control manager 101 turns on the data acquisition circuit 102 and cuts off the memory power supply circuit 103. At this time, the memory 104 can operate solely on its own power supply without the memory power supply circuit 103 providing additional power, keeping the memory 104 in a low-power state to ensure the battery life of the portable electronic product 100, thereby ensuring that the acquired data can be completely stored in the memory 104 and avoiding data loss.

[0073] In the above embodiments, before controlling the data acquisition circuit 102 and / or the memory power supply circuit 103 to turn on and off, the control manager 101 can also control the power restart of the memory 104. That is, a storage operation is performed on the memory 104 each time the communication mode of the memory 104 is switched.

[0074] As mentioned earlier, in existing electronic products with multiple communication modes, users usually need to perform this operation through an external physical switch. In this embodiment, the intelligent switching of the control manager 101 eliminates the need for users to manually switch the physical switch to change the communication mode of the memory 104. This not only avoids errors caused by complicated operations during data storage and transmission in the portable electronic product 100, but also improves the ease of use of the portable electronic product 100.

[0075] Figure 5 Is it like this? Figure 1 A schematic diagram of the circuitry of the control manager 101 in the internal circuitry shown; as follows: Figure 5As shown, the control manager 101 has a port 11 for detecting access of the PC or USB host 105, an SPI communication port 12, and an SDIO communication port 13, which can be connected to the access detection port 51 of the access detection circuit 106 and the SPI communication port 41 and the SDIO communication port 42 of the memory 104 respectively to complete the functions of monitoring whether the PC or USB host 105 is accessed and switching the communication mode of the memory 104.

[0076] In the above embodiment, as shown, Figure 1 The portable electronic product 100 further includes an internal power supply 107 and a voltage conversion circuit 108 connected to the internal power supply 107 and the control manager 101 and converting the voltage of the internal power supply 107 to a pre-set voltage value under the control of the control manager 101 to supply power to the portable electronic product 100.

[0077] For example, the internal power supply 107 can be a lithium battery with an output voltage of 3.5V-4.4V, and the voltage conversion circuit 108 can convert the output voltage of the lithium battery to 3.3V to supply power to the portable electronic product 100, thereby avoiding data transmission failure caused by unstable voltage.

[0078] In some embodiments, as shown, Figure 1 The portable electronic product 100 further includes an electronic switch 109 connected between the control manager 101 and the data acquisition circuit 102, which is turned on or off under the control of the control manager 101. The electronic switch 109 can be used as a switch for the data acquisition circuit 102 to perform switching operation on the data acquisition function of the portable electronic product 100 according to the control of the control manager 101. Thus, the performance of the data acquisition circuit 102 is further improved by the electronic switch 109.

[0079] In the above embodiment, when the access detection circuit 106 detects that the portable electronic product 100 is not accessed by the PC or USB host 105 and no detection signal (such as electrode signal) is obtained, the control manager 101 controls the data acquisition circuit 102 and the memory supply circuit 103 to be disconnected, and the portable electronic product 100 enters the ultra-low power consumption mode.

[0080] In this ultra-low power consumption mode, no operation is performed inside the portable electronic product 100, so that its power consumption is minimized, avoiding additional power consumption of the portable electronic product 100 in the state of storage or dormancy without performing action, prolonging the service life of the internal power supply 107.

[0081] In some embodiments, the portable electronic product 100 is a wearable electrocardiogram recorder. The wearable electrocardiogram recorder is used to collect electrode signals of a human body and store the signals in a memory, and transmit the signals to an external device such as a PC through a USB interface or other interfaces when needed.

[0082] The existing wearable electrocardiogram recorder usually needs a user to wear it continuously for seven days to collect electrocardiogram signal data of the user for seven days, and transmit the data to an external device such as a PC, so as to analyze the electrocardiogram signal data of the user and determine the health status of the user. In the embodiments of the present application, the communication mode of the memory of the wearable electrocardiogram recorder can be intelligently switched as needed. For example, when the user wears the electrocardiogram recorder to collect data, the communication mode of the memory is switched to a communication mode (first communication mode) with a lower data transmission rate, i.e. no data transmission with a PC or a USB host, so as to ensure the use time of the electrocardiogram recorder and avoid power consumption too large to cause the electrocardiogram recorder to run out of power and be unable to collect data. When the data collection is completed and the electrocardiogram recorder is connected to an external PC or a USB host, the communication mode of the memory can be switched to a communication mode (second communication mode) with a higher data transmission rate, so that the memory can quickly transmit a large amount of collected data to the external PC or the USB host, thereby reducing the data transmission time and improving the user experience.

[0083] Moreover, the switching of the above communication modes is completed in the wearable electrocardiogram recorder, without the need for the user to manually set, thereby avoiding the user to make an error switching due to tedious operation in the self-switching process and improving the use convenience of the wearable electrocardiogram recorder.

[0084] Figure 6 is a working flow diagram of the portable electronic product 100 of the embodiments of the present application. As shown in Figure 6 After the portable electronic product 100 is started, the following operations are performed:

[0085] First, it is judged whether to enter an ultra-low power consumption mode. If it is needed to enter the ultra-low power consumption mode, the control manager 101 turns off the power supply of the data collection circuit 102, the memory power supply circuit 103 and the memory 104, and then it is judged whether the portable electronic product 100 needs to be restored. If the portable electronic product 100 does not need to be restored, the portable electronic product 100 performs cycle 1 until it is restored.

[0086] Then, when the portable electronic product 100 is restored and does not need to enter the ultra-low power consumption mode, the control manager 101 judges whether the communication mode of the memory needs to be switched. If the communication mode of the memory does not need to be switched, the portable electronic product 100 performs cycle 2.

[0087] Then, when the portable electronic product 100 needs to switch the communication mode of the memory 104, the power supply of the memory 104 is first turned off, and then the need to switch to the first communication mode or the second communication mode is determined according to the pre-set condition as described above, and the switching is performed by the control manager 101.

[0088] Finally, after the portable electronic product 100 performs the required operation, such as data acquisition and data transmission, in the current communication mode of the memory, the power supply of the memory 104 is restarted again, and the cycle ③ is performed again.

[0089] Through the above workflow, the portable electronic product 100 can intelligently switch the communication mode of the memory 104 as needed, improving the convenience of using the portable electronic product.

[0090] According to the portable electronic product provided by the embodiment of the present application, the communication mode of the memory can be intelligently switched according to the power consumption and the data transmission rate, which can reduce the power consumption of the portable product during use, prolong the use time of the portable electronic product, and thus ensure the amount of data for data analysis, improve the usability of the data obtained by the portable electronic product, and further reduce the waiting time of the memory when switching the communication mode, and improve the use efficiency of the portable electronic product.

[0091] In addition, the portable electronic product also has a low-power mode, which can reduce the power consumption of the portable electronic product to the minimum in the case of no use and no data transmission, thereby prolonging the service life of the portable electronic product.

[0092] It should be noted that the portable electronic product can also be other electronic products with memory communication function, and the present application does not limit this.
