Background

When a general embedded device with a file system is produced in a batch, the following methods are generally used to initialize data in the file system in a non-volatile memory.

The method comprises the following steps: the method comprises the steps of manufacturing default parameters, data and the like into a file system mirror image, burning the file system mirror image into external storage equipment (such as FLASH) by using a tool, and then carrying out production in a patch mounting mode. The disadvantage of this method is that special procedures are required.

The second method comprises the following steps: the default parameters, data and the like are made into a file system mirror image, the file system mirror image is copied to a movable storage device (such as an SD card and a U disk), then the movable storage device is inserted into a device to be initialized, and the device to be initialized copies the internal mirror image to an external storage device after detecting the movable storage device. The disadvantage of this approach is that it requires additional hardware device interface such as (USB/SD card port) support.

The third method comprises the following steps: and converting the structured parameter documents arranged according to the storage address sequence into binary parameter documents by a binary conversion tool, and then sequentially writing the binary parameter documents into the electric energy meter according to the storage address sequence. The disadvantages of this method are: this is not applicable to a parameter storage management system with a file system, because the parameter address of the file system is not an actual physical address but a logical address based on the characteristics of the file system, and the binary file cannot be generated simply in a manner of arranging the storage addresses in order. In addition, because the parameters are loaded and written by the electric energy meter program, the electric energy meter program is required to maintain the corresponding information table of the default parameters and the written parameter positions, and if the parameters are changed, the electric energy meter initialization program is also required to be correspondingly changed. Moreover, if the parameters in the file system exist in the database, the database needs to be operated for many times, and the initialization time is long.

In view of the above problems, no effective solution has been proposed.
