Method for storing configuration information

Abstract

The invention provides a method for storing configuration information applied to equipment with an embedded system. The equipment provides an internal memory, and the internal memory comprises a first environment variable partition; the first environment variable partition includes a first partition and a second partition; the equipment provides a storage unit, and the storage unit comprises a second environment variable partition; the structure of the second environment variable partition is the same as that of the first environment variable partition; the method further comprises the following steps of step S1, acquiring the configuration information and loading the configuration information to the internal memory; step S2, writing the configuration information into the first environment variable partition according to an external first system command; and step S3, writing the configuration information which is conserved in the first environment variable partition into the second environment variable partition according to an external second system command. The technical scheme of the invention has the beneficial effect that data associated with the configuration information can be conveniently and quickly stored in the storage unit of the equipment.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for storing configuration information. Background technique [0002] An environment variable is an object with a specific name in the operating system, which contains information that one or more applications will use. The data of environment variables in embedded devices is usually stored in the environment variable partition in the form of strings, as shown below: [0003] variable name = the value corresponding to the variable name (the value is in string format) [0004] For example: ip_address = 192.168.1.1 device_name = embedded_robot [0005] However, the partition for storing simple string variables cannot meet the needs of convenient and fast storage of data blocks corresponding to configuration information, because data blocks are specifically binary bit streams, and it is not convenient to use strings to represent their data values ​​or names. For ex...

[0005] However, the partition for storing simple string variables cannot meet the needs of convenient and fast storage of data blocks corresponding to configuration information, because data blocks are specifically binary bit streams, and it is not convenient to use strings to represent their data values ​​or names. For example, bitmap data and encrypted information are difficult to store in the form of strings
