As shown in the figure, the data storage method based on the flash memory includes:

[0033] 101. Obtain data to be transmitted from an external device through the flash memory.

[0034] In an embodiment of the present application, the electronic device may include a flash memory, or the electronic device itself is a flash memory, and the flash memory may also be referred to as a flash memory chip or a flash memory device.

[0035] In a specific implementation, a communication connection can be established between the flash memory and the external device, and the communication connection may include a wireless communication connection and / or a wired communication connection. The wireless communication connection may include at least one of the following: Bluetooth, infrared, visible light, millimeter wave, Lora, Near Field Communication (NFC), Zigbee, etc., which are not limited here.

[0040] In a specific implementation, since both a wireless communication connection and a wired communication connection can be established between the flash memory and the external device, multiple data transmission channels can be obtained. In this way, the data transmission channel between the data to be transmitted and the external device can be determined, and multiple data transmission channels can be obtained.

[0041] Optionally, the above step 102, determining a data transmission channel between the data to be transmitted and the external device to obtain multiple data transmission channels, may include the following steps:

[0042] 21. Obtain a physical data transmission channel between the flash memory and the external device to obtain m physical data transmission channels, where m is a positive integer;

[0043] 22. Acquire the wireless data transmission channel between the flash memory and the external device to obtain n wireless data transmission channels, where n is a positive integer;

When the number of the reference data transmission channels is less than or equal to m+n, obtain data transmission channels of a number equal to the number of the reference data transmission channels from the m physical data transmission channels and the n wireless data transmission channels to obtain the multiple data transmission channels;

[0047] 26. When the number of the reference data transmission channels is greater than m+n, obtain all the data transmission channels from the m physical data transmission channels and the n wireless data transmission channels to obtain the multiple data transmission channels.

[0048] In an embodiment of the present application, a physical data transmission channel between a flash memory and an external device can be obtained to obtain m physical data transmission channels, where m is a positive integer. A wireless data transmission channel between a flash memory and an external device can also be obtained to obtain n wireless data transmission channels, where n is a positive integer. Furthermore, the amount of data to be transmitted can be determined, and a mapping relationship between a preset amount of data and the number of data transmission channels can be pre-stored. Then, the number of reference data transmission channels corresponding to the amount of data can be determined based on the mapping relationship. When the number of reference data transmission channels is less than or equal to m+n, data transmission channels equal to the number of reference data transmission channels are obtained from the m physical data transmission channels and the n wireless data transmission channels to obtain multiple data transmission channels. When the number of reference data transmission channels is greater than m+n, all data transmission channels are obtained from the m physical data transmission channels and the n wireless data transmission channels to obtain multiple data transmission channels. In this way, as many data transmission channels as possible can be selected to realize data transmission, which helps to improve data transmission efficiency.

[0049] Optionally, the multiple data transmission channels further include a data transmission channel, the external device is further connected to a first device, and the first device is communicatively connected to the flash memory, and the following steps may also be included:

In this way, as many data transmission channels as possible can be selected to realize data transmission, which helps to improve data transmission efficiency.

[0055] 103. Determine attribute information of each of the multiple data transmission channels to obtain multiple attribute information.

[0056] In the embodiment of the present application, the attribute information may include at least one of the following: data transmission channel type, bandwidth, packet loss rate, disconnection rate, network delay, data transmission rate, etc., which are not limited here.

[0057] In a specific implementation, the attribute information of each of the multiple data transmission channels may be determined to obtain multiple attribute information.

[0058] 104. Divide the data to be transmitted into multiple data sets according to the multiple attribute information.

[0059] Among them, different attribute information represents the characteristics of different data transmission channels, and then the data to be transmitted can be divided into multiple data sets according to multiple attribute information. Since different data transmission channels have different data transmission security, data with high data transmission security requirements can give priority to wired data transmission channels, and conversely, data with low data transmission security requirements can choose wired data transmission channels or wireless data transmission channels.

[0060] Optionally, the above step 104, dividing the data to be transmitted into multiple data sets according to the multiple attribute information, may include the following steps:

[0061] 41. Determine the security level of each of the multiple data transmission channels according to the multiple attribute information to obtain multiple security levels;

[0062] 42. Divide the data to be transmitted into the multiple data sets according to the multiple security levels.

[0063] In an embodiment of the present application, the security level of each of the multiple data transmission channels can be determined according to the multiple attribute information to obtain multiple security levels, that is, the mapping relationship between the preset attribute information and the security level can be pre-stored, and then the security level of each of the multiple data transmission channels can be determined based on the mapping relationship to obtain multiple security levels, and then the data to be transmitted can be divided into multiple data sets according to the multiple security levels, that is, the data to be transmitted can be split into multiple data, and the security level score of each data is determined to obtain multiple security level scores, and the multiple data are numbered based on the security level score, the smaller the number, the lower the security level, and the larger the number, the higher the security level, and the data transmission rates of the multiple data transmission channels are determined to obtain multiple data transmission rates, and the multiple data transmission channels are sorted based on the multiple security levels so that the security level order is from low to high, and the data volume proportions of the multiple data transmission channels are determined according to the multiple data transmission rates to obtain multiple data volume proportions, and the multiple data are divided into multiple data sets based on the multiple data volume proportions and the numbering order. In this way, not only the data with high data security requirements are allocated to the data transmission channel with high security, but also the amount of data to be transmitted by each data transmission channel can be determined based on the data transmission rate of each data transmission channel, which helps to ensure data transmission efficiency.

[0064] Optionally, the above step 42, dividing the data to be transmitted into the multiple data sets according to the multiple security levels, may include the following steps:

[0065] 421. Determine data transmission rates of the multiple data transmission channels to obtain multiple data transmission rates;

[0066] 422. Divide the data to be transmitted according to the multiple data transmission rates to obtain multiple reference data sets;

[0068] 424. Process corresponding data sets among the multiple reference data sets according to the multiple data processing parameters to obtain the multiple data sets.

[0069] In an embodiment of the present application, the data transmission rates of multiple data transmission channels can be determined to obtain multiple data transmission rates. The data to be transmitted can also be divided according to the multiple data transmission rates to obtain multiple reference data sets. Specifically, the data to be transmitted can be divided into multiple data, and a security level score of each data can be determined to obtain multiple security level scores. The multiple data can be numbered based on the security level scores, the smaller the number, the lower the security level, and the larger the number, the higher the security level. The data transmission rates of multiple data transmission channels can be determined to obtain multiple data transmission rates. The multiple data transmission channels can be sorted based on the multiple security levels so that the security levels are in an ascending order. The multiple data transmission rates can be determined based on the multiple security levels. The data volume proportions of multiple data transmission channels are obtained, and multiple data volume proportions are divided into multiple data sets based on the multiple data volume proportions and the numbering order. In this way, not only the data with high data security requirements are allocated to the data transmission channels with high security, but also the amount of data that needs to be transmitted by each data transmission channel can be determined based on the data transmission rate of each data transmission channel, which helps to ensure data transmission efficiency. The data processing parameters corresponding to each security level in the multiple security levels can also be determined to obtain multiple data processing parameters, wherein the data processing parameters may include at least one of the following: whether encryption is required, encryption algorithm, encryption algorithm control parameters, whether compression, compression method, etc., which are not limited here.

[0070] Finally, corresponding data sets in multiple reference data sets can be processed according to multiple data processing parameters to obtain multiple data sets, thereby ensuring not only the security of data transmission but also the data transmission rate.

[0071] 105. Transmit the multiple data sets to the flash memory according to the multiple data transmission channels.

[0072] In a specific implementation, multiple data sets can be transmitted to the flash memory according to multiple data transmission channels, that is, each data set is transmitted to the flash memory through a corresponding data transmission channel.

[0073] 106. Assemble the multiple data sets in the flash memory to obtain the data to be transmitted.

[0074] Among them, each data set can include multiple data, each data can correspond to an index, and each data set can correspond to an index table. Then, in the flash memory, based on the index tables of multiple data sets, the data can be assembled in the corresponding index order to obtain the data to be transmitted. In this way, the data transmission rate can be guaranteed.

[0075] It can be seen that the flash memory-based data storage method described in the embodiment of the present application is applied to an electronic device, which includes a flash memory. The data to be transmitted of an external device is obtained through the flash memory, and the data transmission channel between the data to be transmitted and the external device is determined to obtain multiple data transmission channels. The attribute information of each data transmission channel in the multiple data transmission channels is determined to obtain multiple attribute information. The data to be transmitted is divided into multiple data sets according to the multiple attribute information, and the multiple data sets are transmitted to the flash memory according to the multiple data transmission channels. The multiple data sets are assembled in the flash memory to obtain the data to be transmitted. Multiple data transmission channels can be obtained, and the data to be transmitted is divided into multiple data sets corresponding to the attribute information of the multiple data transmission channels, and then the multiple data sets are transmitted to the corresponding data transmission channels. Finally, the multiple data sets that have been transmitted are assembled into the data to be transmitted. In this way, the storage efficiency of the flash memory can be improved.

[0084] The specific description of the above steps 201 to 206 can refer to the above Figure 1 The corresponding steps of the described flash memory-based data storage method are not repeated here.

[0085] It can be seen that the flash memory-based data storage method described in the embodiment of the present application is applied to an electronic device, which includes a flash memory. When the data size of the data to be transmitted is greater than a set threshold, it means that the data volume of the data to be transmitted is large.
