Fig. 1 is a schematic diagram of an implementation environment in accordance with the present invention. As shown in fig. 1, the implementation environment includes: an electronic device 20 and a memory card 10 interfacing with the electronic device 20. When the memory card 10 is connected with the electronic device 20 through the interface, the electronic device 20 loads data on the memory card 10 through the identification program, and when the data cannot be loaded normally, another identification program is adopted to load data on the memory card 10 until the data is loaded normally on the memory card 10, so that the memory card is identified successfully. The memory Card 10 may be an SD Card (Secure Digital Memory Card, secure digital Card), TF Card (Trans-Flash Card), CF Card (Compact Flash Card), MMC Card (multimedia Card), or the like, and the specific implementation is not limited by the present embodiment. The electronic device 20 may be a smart phone, a tablet computer, a camera, a vehicle-mounted device, an unmanned aerial vehicle, etc., and the specific implementation manner is not limited by the embodiment.
Fig. 2 is a flowchart illustrating a method of identifying a memory card according to an exemplary embodiment. As shown in fig. 2, the identification method of the memory card may include the following steps.
In step S110, the type parameter of the memory card is read by the memory card protocol command.
The memory card is an independent storage medium which can be used for electronic equipment such as mobile phones, computers and the like. In one exemplary embodiment, the memory card may be an SD card, TF card, CF card, MMC card, or the like.
It should be noted that the memory card is pluggable. After the memory card is inserted into the interface of the electronic equipment, the electronic equipment is connected with the interface of the memory card, and after the memory card is successfully identified, the data interaction with the memory card is realized.
The memory card protocol command is an instruction to make a communication connection between the memory card and the electronic device based on a communication protocol. In one exemplary embodiment, the memory card and the electronic device interact with protocol commands via the SD card protocol.
The type parameter of the memory card is a parameter describing various types of characteristics of the memory card. The type parameters of the memory card include, but are not limited to, at least one of the parameters of the memory card's manufacturing identification (manufacturer identification), OEM (Original Equipment Manufacturer ) ID, SD card capacity, and SD card speed level.
The method comprises the steps that a specific memory card protocol command is preset in the electronic equipment, after the memory card is inserted into an interface of the electronic equipment, the electronic equipment detects the insertion of the memory card, the memory card protocol command is sent to the memory card, and after the memory card receives the memory card protocol command sent by the electronic equipment, relevant type parameters are replied to the electronic equipment.
In one exemplary embodiment, a method of acquiring a type parameter of a memory card through an SD card protocol command is as follows.
The electronic device sends SD card protocol commands such as CMD2, CMD9, CMD13 to the memory card, and reads the OEM ID and ManufacturerID, SD card capacity size, uhs speed grade, speed class, and the like of the memory card, respectively.
In step S130, at least two kinds of identification programs corresponding to the type parameters of the memory card are obtained according to the correspondence between the preset identification programs and the type parameter ranges.
The identification program is a software program for loading data on the memory card and is used for controlling the data loading process of the memory card in the electronic device. In one exemplary embodiment, the identification program is a device driver by which the memory card is data loaded. It will be appreciated that each identification procedure is capable of identifying a range of type parameters. Thus, each identification procedure corresponds to a range of type parameters.
The types of parameters corresponding to the different identification programs are different to a certain extent, so that for a certain type of memory card, not all identification programs can successfully identify the type of parameters. When the type parameter of the memory card is in the range of the type parameter corresponding to the identification program, the identification program can normally load data to the memory card; when the type parameter of the memory card is not within the type parameter range corresponding to the identification program, the identification program may not normally load data on the memory card, so that the memory card cannot be successfully identified.
In step S150, the memory card is loaded with data by at least two kinds of identification programs in turn until the memory card is successfully identified.
And further loading data to the memory card by acquiring at least two identification programs. When one identification program is adopted and the data loading of the memory card cannot be carried out normally, the other identification program is adopted to carry out the data loading of the memory card until the data loading is carried out normally, namely the memory card is successfully identified.
When at least two kinds of identification programs are adopted to load data on the memory card in turn, each identification program has a certain sequence when being loaded. The memory card can be loaded in turn according to the order of the memory size occupied by each identification program, the frequency order of data loading according to each identification program, and other modes.
In one exemplary embodiment, the memory card is data loaded using the following architecture.

{Mid_2，Oid_2，Capabcity_2，Class_2，Uhs_2，Sd_param_2}，
{Mid_3，Oid_3，Capabcity_3，Class_1，Uhs_3，Sd_param_3}，
........
}SD_FACTORY_INFO
After the identification programs are numbered 1, 2 and 3 … …, the data loading is sequentially carried out on the memory cards according to the sequence of the numbers 1, 2 and 3 … … until the data loading is carried out normally.
By using the method, at least two corresponding identification programs are acquired according to the type parameters of the memory card, and when one identification program cannot normally load data on the memory card, the other identification programs are adopted to load data on the memory card, so that the success rate of memory card identification is improved.
Fig. 3 is a description of details of step S130 shown according to an exemplary embodiment. This step S130 may include the following steps.
In step S131, the type parameter ranges corresponding to the various recognition programs are respectively matched with the type parameters, so as to obtain corresponding matching degrees.
The matching degree is the matching degree of the type parameter range corresponding to the identification program and the type parameter.
The matching operation is to calculate the matching degree of the type parameter range and the type parameter corresponding to the identification program, obtain the distance between the type parameter range and the type parameter, and further obtain the matching degree between the identification program and the type parameter.
When the type parameter is in the type parameter range corresponding to the identification program, the matching degree between the identification program and the type parameter is higher; when the type parameter is not in the type parameter range corresponding to the identification program, the matching degree between the identification program and the type parameter is smaller, and the farther the distance between the type parameter and the type parameter range is, the smaller the matching degree is.
The various identification programs may be identification programs stored locally on the electronic device or may be identification programs stored on the server.
In step S133, at least two kinds of recognition programs are selected from among various kinds of different recognition programs according to the degree of matching.
And selecting at least two kinds of identification programs according to different matching degrees between the type parameters and various different identification programs. The matching degree threshold value can be preset, and at least two recognition programs with matching degree exceeding the matching degree threshold value are selected; the number of the identification programs can be preset, and then the preset number of the identification programs can be selected according to the degree of matching; other ways of selecting at least two identification procedures from a variety of different identification procedures are also possible, and are not limited in this regard.
By using the method, at least two kinds of identification programs are selected according to the matching degree of various different identification programs and type parameters, and then the at least two kinds of identification programs are adopted to load data on the memory card in turn, so that the success rate of memory card identification is greatly improved.
Alternatively, in an exemplary embodiment, step S131 may include the following steps.
In step S1311, the type parameter ranges corresponding to all the recognition programs in the local storage are respectively matched with the type parameters, so as to obtain corresponding matching degrees.
It should be noted that, the electronic device downloads the identification program of one or more different memory cards in advance and stores the identification program in the local storage.
And the corresponding matching degree is obtained through the matching operation of the type parameter range corresponding to the identification program in the local storage and the type parameter of the memory card, so that the identification program is selected according to the matching degree to load data on the memory card, and the identification speed of the memory card is greatly improved.
Alternatively, fig. 4 is a description of details of step S131 shown according to an exemplary embodiment. The identification program is stored in the server, and this step S131 may include the following steps.
In step S1313, a plurality of different recognition programs in the server are acquired.
In one exemplary embodiment, the various identification programs are obtained by downloading in the SD card usage platform of the server.
In step S1315, the type parameter ranges corresponding to the multiple different recognition programs are respectively matched with the type parameters, so as to obtain corresponding matching degrees.
By the method, the corresponding matching degree is obtained by respectively carrying out matching operation on the type parameter range corresponding to the identification program and the type parameter of the memory card through acquiring the identification program in the server, and then the identification program is selected according to the matching degree to carry out data loading on the memory card.
Fig. 5 is a detailed description of step S150 shown for the corresponding embodiments of fig. 2, 3 and 4, according to an exemplary embodiment. The identification program is stored in a server or a local storage, and this step S150 may include the following steps.
In step S151, the selected at least two identification programs are sorted according to the frequency of data loading, so as to obtain a sorting result.
The frequency of data loading is the number of times the identification program normally loads data to the memory card within a certain period. The greater the frequency, the greater the number of times the corresponding identification program normally performs data loading.
For example, the frequencies of data loading performed by the selected recognition programs A1, A2, A3 and A4 are 600, 5000, 1000 and 800 respectively, and the sorting results obtained according to the frequencies are A2, A3, A4 and A1.
In step S153, the memory cards are sequentially loaded with data according to the sorting result by using at least two kinds of identification programs until the memory cards are successfully identified.
And sequentially carrying out data loading on the memory card by adopting at least two identification programs according to the sorting result, and when one identification program cannot normally carry out data loading on the memory card, carrying out data loading on the memory card by adopting the next identification program according to the sorting result until the memory card is normally loaded, namely successfully identifying the memory card.
For example, at least two kinds of identification programs corresponding to the type parameter of the memory card are identification programs A1, A2, A3, respectively, and the sorting result obtained according to the frequency of data loading is A2, A3, A1. When the data loading is carried out on the memory card, firstly, adopting the identification program A2 to carry out the data loading on the memory card, and if the data loading is carried out normally, namely the memory card is successfully identified, then, no other identification program is adopted to carry out the data loading on the memory card; when the identification program A2 cannot normally load data on the memory card, the identification program A3 is adopted to load data on the memory card, and if the memory card is successfully identified after the data is normally loaded, the memory card is not loaded by other identification programs; when the identification program A3 cannot normally load data on the memory card, the identification program A1 is adopted to load data on the memory card, and if the data is loaded normally, the memory card is successfully identified.
By using the method, the selected identification programs are ordered according to the frequency of data loading, and then the identification programs are adopted to load the data of the memory cards in turn according to the ordering result, namely, the identification programs with high frequency are preferentially adopted to load the data, so that the success rate of identifying the memory cards is greatly improved.
