Obviously, for ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative labor.

[0044] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0045] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in a sequence other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0046] In related technologies, the process of performing NV backup of calibration parameters may include the following steps:

[0047] Step 1: Turn on the function module and enter the calibration mode;

[0048] Step 2: Perform calibration and write the calibration parameters into the corresponding NV memory (Nonvolatile random access memory);

[0049] Step 3: Filter and back up the NV parameters in the NV memory using the original filter file to obtain an NV backup file, wherein the original filter file can back up the calibration parameters from multiple functional modules;

[0050] Step 4: Shut down the module and exit calibration mode.

[0051] In the application, NV parameters in the NV memory include written parameters and unwritten parameters. Written parameters are NV parameters with valid values, that is, written parameters are NV parameters with non-empty values, while unwritten parameters are NV parameters with empty values. When filtering the NV parameters in the NV memory using the original filter file, the unwritten parameters in the NV memory can be filtered out, so that only the written parameters in the NV memory are backed up.

[0052] Since the original filter file can back up the calibration parameters from multiple functional modules, the original filter file includes parameters indicating the written parameters and unwritten parameters of multiple functional modules. Therefore, when the original filter file is used to filter the NV parameters in the NV memory in step 2, the NV parameters are matched with the written parameters and unwritten parameters indicating other functional modules in the original filter file, which leads to the problem of long backup time and high cost.

[0053] In order to solve this technical problem, an embodiment of the present application provides a parameter backup method, which can be applied to an electronic device;

[0054] The electronic devices described in the embodiments of the present application may include smart phones (such as Android phones, iOS phones, Windows Phone phones, etc.), tablet computers, PDAs, laptops, video matrices, monitoring platforms, mobile Internet devices (MIDs) or wearable devices, etc. The above are only examples and not exhaustive, including but not limited to the above devices. Of course, the above electronic devices can also be servers, for example, cloud servers.

[0055] like Figure 1 As shown, the method may include the following steps:

[0056] Step 101: Obtain the NV backup file corresponding to the functional module.

[0057] Among them, the NV backup file is obtained by using the original filter file to perform NV backup on the calibration parameters of the functional module. The original filter file is used to perform NV backup on the calibration parameters of at least two functional modules. The NV backup file and the original filter file have different parameter expressions for the same parameter.

[0058] It should be understood that when the file formats of the NV backup file and the original filter file are different, the parameter expressions of the NV backup file and the original filter file for the same parameter will be different; or, even if the file formats of the NV backup file and the original filter file are the same, the parameters in the original filter file will be encrypted for security reasons, so the parameter expressions of the NV backup file and the original filter file for the same parameter will be different.

[0059] It should be noted that encrypting the parameters in the original filter file based on security considerations is only an optional implementation method that makes the NV backup file and the original filter file have different parameter expressions for the same parameter, under the premise that the file format of the NV backup file and the original filter file are the same. This embodiment does not make any specific limitations on this.

[0060] In this embodiment, before updating the original filter file, the calibration parameters of the functional module are still backed up using the original filter file. Specifically, the NV memory corresponding to the functional module is determined; the calibration parameters of the functional module are written into the NV memory; the NV parameters in the NV memory are read and the original filter file is used to filter the write parameters from the NV parameters. The write parameters are the parameters whose values ​​are not null in the NV parameters; and the written parameters are backed up to obtain an NV backup file.

[0061] It should be understood that the parameter expressions for the same parameter in the NV memory and the original filter file may be different. In this case, the original filter file is used to filter the NV parameters by identifying the parameters.

[0062] Step 102: Delete the parameters in the original filter file that do not match the parameters in the NV backup file to obtain an updated filter file.

[0063] This embodiment provides the following two methods to delete parameters in the original filter file that do not match the parameters in the NV backup file:

[0064] First, it is implemented according to the NV status of each parameter in the original filter file.

[0065] The NV state includes a first state or a second state, the first state is used to indicate a mismatch with the written parameters, and the second state is used to indicate a match with the written parameters.

[0066] It should be understood that the NV state of each parameter in the original filter file is obtained after the original filter file filters the NV parameters in the NV memory. Therefore, the parameters in the original filter file with the NV state of the first state actually include two types of parameters: one type is the unwritten parameters in the NV memory, and the other type is the NV parameters in the other NV memory, where the other NV memory is used to store calibration parameters for other functional modules.

[0067] Specifically, when deleting parameters in the original filter file that do not match the parameters in the NV backup file according to the NV state, the parameters in the original filter file whose NV state is the first state are directly deleted to obtain an updated filter file.

[0068] Second, implementation based on the perspective of data sets.

[0069] Because the original filter file and the NV backup file have different parameter expressions for the same parameter, when using this method, the parameters in the original filter file and the NV backup file need to be formatted in the same way.

[0070] In order to save conversion workload and improve the efficiency of obtaining the updated filter file subsequently, when unifying the format of the parameters in the original filter file and the parameters in the NV backup file, the parameter expression method in the original filter file is obtained; the parameters in the NV backup file are expressed according to the parameter expression method to obtain a converted NV backup file; a first data set consisting of the parameters in the original filter file and a second data set consisting of the parameters in the converted NV backup file are determined; the union of the first data set and the second data set is determined; the parameters in the union in the original filter file are deleted to obtain an updated filter file.

[0071] Furthermore, in order to further improve the efficiency of obtaining the updated file, in this embodiment, the first data set can be represented by the identifiers of the parameters in the original filter file, and similarly, the second data set can be represented by the identifiers of the parameters in the converted NV backup file.

[0072] Specifically, a first NV list identification file corresponding to the original filter file and a second NV list identification file corresponding to the converted NV backup file are obtained, the identifiers in the first NV list identification file have a one-to-one correspondence with the parameters in the original filter file, and the identifiers in the second NV list identification file have a one-to-one correspondence with the parameters in the converted NV backup file; determine that the identifiers in the first NV list identification file constitute a first data set, and the identifiers in the second NV list identification file constitute a second data set.

[0073] It should be understood that when the NV backup file is converted into the converted NV backup file, the parameter identification in the NV backup file does not change, so the second NV list identification file corresponding to the converted NV backup file is actually the NV list identification file corresponding to the NV backup file.

[0074] Step 103 : Determine that the updated filter file is the filter file corresponding to the functional module, and when it is necessary to perform NV backup on the calibration parameters of the functional module again, perform NV backup on the calibration parameters of the functional module using the updated filter file.

[0075] In this embodiment, after obtaining an updated filter file, when it is necessary to perform an NV backup of the calibration parameters of the functional module again, the updated filter file is used to perform an NV backup of the calibration parameters of the functional module. Specifically, the NV memory corresponding to the functional module is determined; the calibration parameters of the functional module are written into the NV memory; the NV parameters in the NV memory are read and the written parameters are filtered from the NV parameters using the updated original filter file; and the written parameters are backed up to obtain an NV backup file.

[0076] In order to clearly show the user the NV backup time that can be saved by adopting the parameter backup method provided in this embodiment, in another embodiment of the present application, after using the updated filter file to perform NV backup on the calibration parameters of the functional module, the first time required for performing NV backup on the functional module for a preset number of times using the original filter file and the second time required for performing NV backup on the functional module for a preset number of times using the updated filter file can also be detected; the first time and the second time are displayed according to a preset graphical display method.

[0077] Please refer to Table 1, which is a comparison of the time required to perform NV backup on the calibration parameters of the same functional module under the same test environment using the original filter file and the updated filter file respectively:

[0078]

The NV backup file is obtained by performing an NV backup on the calibration parameters of the functional module using an original filter file. The original filter file is used to perform an NV backup on the calibration parameters of at least two functional modules. The NV backup file and the original filter file have different parameter expressions for the same parameter; parameters in the original filter file that do not match the parameters in the NV backup file are deleted to obtain an updated filter file; the updated filter file is determined to be the filter file corresponding to the functional module, and when the calibration parameters of the functional module need to be backed up again, the updated filter file is used to perform an NV backup on the calibration parameters of the functional module. Since some parameters in the original filter file are deleted, when the calibration parameters of the functional module are backed up using the updated filter file, the NV backup time will be greatly shortened, thereby improving the generation efficiency.
