Detailed Description

The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

In order to ensure that the stored parameter data can be compatible between different software versions, in the related art, the stored parameter data of each software is stored in Flash in a text form, considering that the data stored in the text form has the characteristics of easy parsing and easy compatibility. However, in the above-described related art, since the storage space occupied by each software parameter data stored in a text form is large, there is a problem in that the efficiency of storing and reading each software parameter data is low due to the much time consuming for storing and reading each software parameter data. In order to solve the technical problems, the embodiment of the invention provides a data storage method.

Next, a description will be first given of a data storage method provided in an embodiment of the present invention.

Fig. 1 is a flow chart of a data storage method according to an embodiment of the present invention.

The method is applied to any electronic equipment which needs to be subjected to software updating and software parameter compatibility. For example, a camera in a video monitoring system, an industrial camera, etc., and the embodiment of the present invention is not particularly limited.

Further, the method can be particularly applied to a configuration management module in target software of the electronic device. Obviously, when the target software in the electronic device is updated, the configuration management module is updated accordingly.

As shown in fig. 1, a data storage method provided by an embodiment of the present invention may include the following steps:

S103: when the target software is updated, reading a first storage address of each first software parameter from a specified text file in a preset storage area;

wherein, the first software parameter is: the method comprises the steps that software parameters before and after target software updating are included, a text file is designated to record first storage addresses of all the software parameters before the target software updating, and parameter values in binary forms are recorded in storage spaces indicated by the first storage addresses;

s104: reading parameter values of the first software parameters from the storage areas according to the read first storage addresses;

S105: storing each first software parameter into a storage area according to the data structure of the software parameters set in the updated target software, and obtaining a second storage address of each first software parameter;

s106: and updating the first storage address of each first software parameter in the appointed text file to a corresponding second storage address.

Next, each step in the data storage method shown in fig. 1 is described in detail.

It should be noted that, in the embodiment of the present invention, the target software of the electronic device does not refer to a specific target software, but refers to any software installed in the electronic device, where the target software may be management software of the electronic device, for example, management software in an industrial camera, etc., or may be application software installed in the electronic device to provide a certain application function, for example, real-time communication software, etc.

When the target software is management software in the electronic device, the target software can manage all or part of functions provided by the electronic device.

For example, for a camera capable of performing image recognition on a captured image, the functions that the camera can perform include image capture and image recognition, then the camera may include a target software for managing the image capture function and a target software for managing the image recognition function, and the camera may also include a target software for managing the image capture function and the image recognition function, that is, the management of the functions of the camera is performed by one target software. This is reasonable.

Based on the above, when the target software is management software in the electronic device, the software parameters managed by the management configuration module in the target software are the software parameters related to the functions managed by the target software, that is, the software parameters related to the target software.

Also taking a camera capable of image recognition of an acquired image as an example, when a target software for managing an image acquisition function and a target software for managing an image recognition function may be included in the camera, software parameters managed by a management configuration module in the target software for managing the image acquisition function may include software parameters related to image acquisition such as an exposure value, a gain value, etc., and software parameters managed by the management configuration module in the target software for managing the image recognition function may include software parameters related to image recognition such as image characteristics, related parameters of a model for image recognition, etc.

Accordingly, when the camera includes a target software for managing the image capturing function and the image recognition function, that is, when the management of the functions of the camera is implemented by one target software, the software parameters managed by the management configuration module in the target software may include software parameters related to image capturing, such as an exposure value, a gain value, and the like, and software parameters related to image recognition, such as image features, related parameters of a model for image recognition, and the like.

Accordingly, when the target software is application software installed on the electronic device for providing a certain application function, the software parameters managed by the management configuration module in the target software are software parameters related to the application function provided by the target software.

For example, if the target software is the real-time communication software a, the software parameters may be a password and an account number for the user to log in to the real-time communication software a.

It can be appreciated that, before updating the target software, the target software needs to be installed in the electronic device first, and based on this, optionally, in a specific implementation manner, as shown in fig. 2, before updating the target software, a data storage method provided by an embodiment of the present invention further includes the following steps:

S100: when the target software is installed, acquiring parameter values of various software parameters of the target software;

s101: according to the data structure of the software parameters set in the target software, storing the parameter values of the software parameters into a storage area to obtain the storage address of the software parameters;

S102: in the specified text file in the storage area, the storage addresses of the respective software parameters of the target software are stored.

When the installation of the target software is completed, the configuration management module in the target software can acquire the parameter values of the software parameters in the target software from the program code of the target software.

Furthermore, the configuration management module may store parameter values of the respective software parameters into a preset storage area according to a data structure of the software parameters set in the program code of the target software.

The arrangement sequence of the software parameters, the data type and the maximum length of the parameter values of the software parameters are specified in the data structure of the software parameters, so that in order to enable the installed target software to successfully read the parameter values of the software parameters from the storage area according to the data structure in the running process, so as to ensure the normal running of the target software, when the parameter values of the software parameters are stored in the preset storage area, the parameter values of the software parameters are required to be stored into the preset storage area according to the arrangement sequence of the software parameters, the data type and the maximum length of the parameter values of the software parameters, which are specified in the data structure.

For example, the data structure of the software parameters set in the target software is as follows program code 1:

The parameter values of the software parameters a-E in the above-mentioned code stored in the preset memory area are shown in fig. 3.

It should be noted that, as shown in fig. 3, it may be referred to that the parameter values of the software parameters a to E are stored in the storage area in the form of binary files, and that storing the parameter values of the respective software parameters in the form of binary files indicates that the respective parameter values are not stored in the form of binary values, and in this storing process, the respective parameter values may be stored in any of binary, decimal, hexadecimal, or the like.

In addition, the preset storage area is a storage area in hardware for storing data, which is provided in the electronic device itself, and for example, the storage area may be a storage chip Flash installed in the electronic device.

Thus, after the parameter values of the software parameters are stored, the electronic device can obtain the storage addresses of the software parameters in the storage area, and further, the storage addresses of the software parameters of the target software are stored in the specified text file in the storage area.

Wherein the starting address of the stored memory address of the first software parameter may be used as the base address of the memory address of the respective software parameter. Further, when the parameter addresses of the respective software parameters are recorded in the specified text file, the initial storage address of the parameter values of the respective software parameters can be determined by the offset from the base address.

Thus, in the specified text file, the parameter address of each recorded software parameter may be expressed in terms of an offset (offset) and a length (length), where len refers to the maximum length of the parameter value of the software parameter set in the program code of the target software.

For example, for the program code 1 described above, the parameter addresses specifying the respective software parameters recorded in the text file may be as shown in table 1 below:

TABLE 1

Parameter identification	Offset	Len
			A	0	4
B	4	4
			C	8	4
D	12	8
			E	20	4

That is, in the electronic device, when the installation of the target software is completed, the parameter values of the respective software parameters in the target software and the storage addresses of the respective software parameters are stored in the preset storage area in binary text form and text form, respectively, instead of being stored together in a single binary text form or text form.

For example, in the industrial camera, when the management software of the industrial camera is installed, the configuration management module in the management software may store the parameter values of the software parameters such as the exposure value and the gain value in the Flash inside the industrial camera in the form of binary text, and further generate a specified text file in which the storage addresses of the software parameters such as the exposure value and the gain value are recorded, and store the specified text file in the Flash inside the industrial camera.

Thus, after the installation of the target software is completed, the function of the target software can be further improved along with the technical development, so that the target software is upgraded; in addition, since in practical applications, the target software with a high version level does not necessarily meet the requirements of practical applications, the installed target software needs to be downgraded. That is, after the installation of the target software is completed, the installed target software may be updated, and the installation manner may include: one of upgrading the target software and downgrading the target software.

After the updating of the target software is completed, in order to ensure that the parameter values of the stored software parameters have compatibility before and after the updating of the target software, so that the updated target software can normally operate, the electronic device needs to store the parameter values of the software parameters in the updated target software according to the data structure of the software parameters set in the updated target software.

Wherein, before and after the updating of the target software, the arrangement sequence of each software parameter in the target software before the updating, and one or more of the data type and the maximum length of the parameter value of each software parameter can be changed. Because the conversion of the same parameter value between different data types is complex, when the data type of the parameter value of a software parameter is changed before and after the updating of the target software, the software parameter can be deleted from the updated program code of the target software, and a new software parameter corresponding to the software parameter can be added. Wherein the physical meaning of the newly added software parameter is the same as the physical meaning of the software parameter, and the two can be characterized by different parameter identifiers.

For example, before the target software is updated, the parameter structure of each software parameter in the target software is shown as the program code 1, and in the updated target software, the data type of the parameter a is changed from int to char, and the maximum length of the data is 8. The parameter structure of each software parameter in the updated target software is as follows in program code 2:

the physical meaning of the software parameter A1 is the same as that of the software parameter A, and the two parameters are characterized by different parameter identifiers.

Correspondingly, the software parameters included in the target software before and after the update are software parameters with unchanged data types of the parameter values before and after the update, and the software parameters with unchanged data types before and after the update can have the same parameter identification in the program codes of the target software before and after the update. When the parameter identification and the storage address of each software parameter are correspondingly recorded in the appointed text file, the parameter identification of the software parameter with unchanged data types before and after updating in the program code of the updated target software is the same as the parameter identification in the appointed text file.

That is, in the program code of the target software before and after the update, the parameter identifiers of the software parameters respectively included may be the same, and the data types representing the parameter values without the software parameters before and after the update are changed; or may be different, a software parameter that characterizes a change in the data type for which there may be a parameter value before and after the update.

Specific: when the program code of the updated target software not only comprises all parameter identifiers in the program code of the target software before updating, but also comprises other parameter identifiers, the updated target software is characterized to be added with new software parameters on the basis of each software parameter of the target software before updating;

When the program code of the updated target software comprises part of parameter identifiers in the program code of the target software before updating and further comprises other parameter identifiers, the data type of the parameter values of one or a plurality of software parameters in the target software before updating can be characterized to be changed in the updated target software; or the updated target software can be characterized in that the software parameters in partial pre-update target software are deleted and new software parameters are added.

Based on this, when the target software update is completed, the updated configuration management module may execute the step S103, and read the first storage addresses of the first software parameters from the specified text file in the preset storage area, that is, read the first storage addresses of the software parameters included before and after the target software update.

The first software parameter is a software parameter included before and after the target software update, specifically, the data type of the parameter value of the first software parameter is unchanged before and after the target software update, and the maximum length of the parameter value of the first software parameter may be changed. That is, the first software parameter is a software parameter whose data type of the parameter value is unchanged before and after the target software update.

Accordingly, when a software parameter changes in the data type of the parameter value before and after the update of the target software, the updated target software will not include the software parameter, but a new software parameter is used to replace the software parameter, and the physical meaning of the software parameter before the update of the target software and the new software parameter after the update are the same. That is, the software parameters whose data types of the parameter values change before and after the update of the target software are not included in the updated target software, and the physical meaning of the software parameters is characterized by another other software parameter that characterizes the same physical meaning as the software parameter.

Obviously, when the parameter identification and the storage address of each software parameter are correspondingly recorded in the specified text file, the first storage address of the first software parameter which is the same as the parameter identification recorded in the specified text file in the program code of the updated target software is read.

Obviously, according to the above description, the specified text file is used for recording the first storage addresses of the respective software parameters before the target software update, and each first storage address indicates a storage space in which a binary-form parameter value of a software parameter is recorded. It is understood that the parameter value stored in each first storage address is the parameter value of each software parameter before the target software is updated.

After the first storage addresses of the first software parameters are read, the configuration management module may further execute the step S104, and reads the parameter values of the first software parameters from the storage area according to the read first storage addresses.

Specifically, for each first software parameter, the configuration management module may first find a storage space indicated by the first storage address of the first software parameter in the storage area, and then may read a binary parameter value recorded in the storage space, so as to read a parameter value of the software parameter.

Based on this, after the parameter values of the respective software parameters are read, the configuration management module may continue to execute the above step S105, store the respective first software parameters into the storage area according to the updated data structure of the software parameters set in the target software, and obtain the second storage address of the respective first software parameters.

The storage address of the first software parameter in the data structure of the software parameter before the update of the target software is read by the management configuration module, and then the starting address of the storage address of the first software parameter is determined.

In this way, when storing the updated parameter values of the first software parameters, the configuration management module may sequentially store the parameter values of the first software parameters in the storage area according to the maximum lengths of the first software parameters specified in the data structure, and obtain the second storage address of each first software parameter, starting from the determined start address according to the arrangement order of the first software specified in the data structure of the software parameters set in the updated target software. Wherein the second memory address may be represented by an offset and len.

Based on this, in an optional implementation manner, the configuration management module obtains the second storage address of each first software parameter may include the following steps:

Step 1: acquiring a starting storage address of a first software parameter in a data structure of the software parameter before updating of the target software;

step 2: and determining the parameter address of each first software parameter based on the initial storage address and the maximum length of the parameter value of each first software parameter in the data structure of the software parameter set in the updated target software.

The initial storage address acquired in step 1 may be determined as the base address. When the parameter values of the first software parameters are read, the arrangement order of the read parameter values can be determined according to the arrangement order of the first software parameters specified in the data structure of the software parameters set in the updated target software, and then, the parameter values are sequentially stored according to the arrangement order from the determined base address, and the length of the storage space occupied by each parameter value is the maximum length of the parameter values of the first software parameters specified in the data structure of the software parameters set in the updated target software.

In this way, when the second storage address is represented by the offset and the len, the offset of the parameter value of the first stored first software parameter is 0, len is the maximum length len1 of the parameter value of the first software parameter, and the offset of the parameter value of the second stored first software parameter is len1, len is the maximum length len2 of the parameter value of the first software parameter; the offset of the stored parameter value of the third first software parameter is len1+len2, len being the maximum length len3 of the parameter value of the first software parameter. By analogy, a second memory address of the parameter value of each of the stored first software parameters may be determined.

In addition, after the parameter value of each software parameter is read, the configuration management module can determine that the parameter value is the current actual parameter value of the software parameter. It should be noted that, for each software parameter, the actual storage space occupied by the parameter value of the software parameter is not the same concept as the storage space indicated by the storage address of the software parameter. Specific:

the actual storage space occupied by the parameter values of the software parameters is as follows: the memory space between the memory location of the first character and the memory location of the last character of the current actual parameter value of the software parameter. The actual memory space occupied by the parameter value of the software parameter is thus the same as the actual length of the current actual parameter value of the software parameter.

Correspondingly, the storage space indicated by the storage address of the software parameter is: the software parameter can occupy the largest memory space, so that the memory space indicated by the memory address of the software parameter has the same size as the maximum length which can be reached by the parameter value of the preset software parameter.

Obviously, when the length of the current actual parameter value of the software parameter is smaller than the maximum length which can be reached by the parameter value of the preset software parameter, the actual storage space occupied by the parameter value of the software parameter is smaller than the storage space indicated by the storage address of the software parameter. In the actual storage application, the storage position, which is not occupied by the current actual parameter value of the software parameter, in the indicated storage space of the storage address of the software parameter can be filled with "0".

For example, the data structure of the software parameters A-E is as shown in program code 1 above, and the memory address of each software parameter recorded in the specified text file may be as shown in Table 1 above.

Accordingly, the actual memory space occupied by the current actual parameter values of the respective software parameters may be as shown in table 2 below:

Parameter identification	Offset	Len
			A	0	4
B	4	4
			C	8	4

Obviously, in table 2 above, the length of the memory space indicated by the memory address of the software parameter D is 8, and the length of the actual memory space occupied by the parameter value of the software parameter D is 3.

It can be appreciated that, during the use of the electronic device, the parameter values of the respective software parameters may be changed for different use scenarios and different users, and the data lengths of the parameter values of the respective software parameters may be different before and after the change.

In order to avoid confusion in the program operation, the target software may therefore define the maximum value of the data length that can be reached by the parameter values of the respective software parameters during the development process, i.e. limit the range of variation of the data length of the parameter values of the respective software parameters, i.e. define the maximum length of the parameter values of the respective software parameters in the data structure of the software parameters.

Furthermore, when each software parameter in the preset storage area allocates a storage space, in order to meet the storage requirement of the parameter value with the maximum length, the storage space can be allocated according to the maximum value of the data length which can be reached by the parameter value of each preset software parameter.

Thus, after obtaining the second storage address of each first software parameter, the configuration management module may execute the above step S106, and update the first storage address of each first software parameter in the specified text file to the corresponding second storage address.

The above-mentioned process of updating the storage address in step S106 may also be considered as the configuration management module generating the second storage address of each new first software parameter.

The specified text file can record the first storage address of each software parameter before updating the target software in various forms. Furthermore, according to the difference of the modes of recording the first storage addresses in the appointed text file, the configuration management module can read the first storage addresses of the first software with unchanged parameter identifiers from the appointed text file in a plurality of different modes.

Alternatively, in one specific implementation, as shown in table 3, the specified text file stores an index entry including a parameter identifier and a storage address.

TABLE 3 Table 3

Parameter identification	Offset	Len
			A	a1	a2
B	b1	b2
			C	c1	C2

Further, in this specific implementation manner, as shown in fig. 4, the step S103 may be to read the first storage address of each first software parameter from the specified text file in the preset storage area, and may include the following steps:

s1031: for each first software parameter, searching a target index entry comprising a parameter identification of the software parameter in a specified text file, and reading a storage address included in the searched target index entry as a first storage address of the software parameter.

In this specific implementation manner, the configuration management module may obtain the parameter identifier of each first software parameter, and further, for each first software parameter, the configuration management module may search, in each index entry included in the specified text file, for a target index entry including the parameter identifier of the software parameter. Obviously, the storage address included in the target index entry is the first storage address of the software parameter, so that the configuration management module can read the storage address included in the searched target index entry and take the storage address as the first storage address of the software parameter.

Accordingly, in this specific implementation manner, the step S106 updates the first storage address of each first software parameter in the specified text file to the corresponding second storage address, and may include the following steps:

S1061: and for each first software parameter, searching a target index entry comprising the parameter identification of the software parameter in the specified text file, and updating the storage address included in the searched second target index entry to a corresponding second storage address.

It will be appreciated that when the first storage address of each first software parameter in the specified text file is not updated, then the index entry included in the specified text file is unchanged. Therefore, in this specific implementation manner, for each first software parameter, the configuration management module may also search for a target index entry including the parameter identifier of the software parameter in each index entry included in the specified text file, so that the storage address included in the searched target index entry may be updated to the corresponding second storage address.

It should be noted that, after the update of the target software is completed, the updated configuration management module may immediately start to execute the data storage method provided in the embodiment of the present invention, so that the updated target software may start to work as soon as possible. Of course, the updated configuration management module may also execute the data storage method provided by the embodiment of the present invention after the target software is updated for a certain period of time. The embodiment of the present invention is not particularly limited in this regard.

It will be appreciated that in the updated target software, new software parameters related to the target software may be added on the basis of the respective software parameters of the target software before the update, and obviously, the new added software parameters also need to be stored in a preset storage area, that is, the new added software parameters may be used as the second software parameters to be added.

In addition, in the updated target software, the new parameter identifier may be used to represent the software parameter whose data type of the parameter value changes before and after the update, and obviously, the new parameter identifier is not included in the program code of the target software before the update and needs to be added, so the new parameter identifier may also be used as the second software parameter to be added. Wherein the parameter value of the second software parameter may be specified by a technician.

Based on this, in an optional implementation manner, as shown in fig. 5, on the basis of the embodiment shown in fig. 1, the data storage method provided in the embodiment of the present invention may further include the following steps:

s107: determining parameter values of second software parameters to be added in the updated target software;

The step S105 may include:

s1051: according to the updated data structure of the software parameters set in the target software, storing the parameter values of the first software parameters and the parameter values of the second software parameters into a storage area, and obtaining the second storage address of the first software parameters and the third storage address of the second software parameters;

wherein the second memory address of each first software parameter and the third memory address of the second software parameter are determined based on the memory address of the first software parameter in the data structure of the software parameter prior to the target software update;

Correspondingly, in this specific implementation manner, the data storage method provided by the embodiment of the present invention may further include the following steps:

s108: and correspondingly storing the parameter identification of the second software parameter and the third storage address in the appointed text file.

In this specific implementation manner, after the parameter values of the first software parameters are read from the storage area according to the read first storage addresses, the configuration management module may further determine the parameter identifier and the parameter value of the second software parameter to be added with the parameters in the updated target software.

The parameter identifier and the parameter value of the second software parameter may be recorded in the program code of the updated target software, or may be recorded in a software configuration file associated with the updated target software.

Furthermore, the configuration management module may store the parameter values of the first software parameters and the parameter values of the second software parameters in the storage area according to the updated data structure of the software parameters set in the target software, and obtain the second storage address of the first software parameters and the third storage address of the second software parameters.

Similar to the above step S105, the arrangement sequence of the first software parameters and the second software parameters, and the data types and the maximum lengths of the first software parameters and the second software parameters are defined in the data structure of the software parameters set in the updated target software, so, in order to ensure that the updated target software can normally operate, the parameter values of the first software parameters and the parameter values of the second software parameters are stored, and also need to be stored according to the data structure of the software parameters set in the updated target software.

The second storage address of each first software parameter and the third storage address of the second software parameter obtained in step S1051 are the same as the manner of obtaining the second storage address of each first software parameter in step S105, and are not described in detail herein.

Thus, after the parameter values of the first software parameters and the parameter values of the second software parameters are completed, the configuration management module can correspondingly store the parameter identification of the second software parameters and the third storage address in the appointed text file. That is, the configuration management module may add new record information in the specified text file, where the record information includes the parameter identification of the second software parameter and the third storage address of the second software parameter.

The configuration management module can correspondingly store the parameter identification and the third storage address of the second software parameter in the appointed text file, and then update the first storage address of each first software parameter in the appointed text file to be the corresponding second storage address; the first storage address of each first software parameter in the appointed text file is updated to be a corresponding second storage address, and then the parameter identification and the third storage address of the second software parameter are correspondingly stored in the appointed text file; and the parameter identification and the third storage address of the second software parameter can be correspondingly stored in the appointed text file at the same time, and the first storage address of each first software parameter in the appointed text file is updated to be the corresponding second storage address. This is reasonable.

For example, if the program code of the target software before the update is as shown in the program code 1 above, the first memory address of the respective software parameters a-E recorded in the specified text file before the update of the target software is as shown in table 1 above, and the parameter values of the respective software parameters a-E stored in binary form are as shown in fig. 3.

The program code for the respective software parameters a-F in the updated target software is shown in program code 3 as follows:

Obviously, after the data storage method shown in fig. 5 is executed, the second storage address of each software parameter a-E and the third storage address of the software parameter F recorded in the specified text file can be obtained, as shown in table 4 below, and the parameter values of each software parameter a-F stored in binary form are shown in fig. 6.

			A	0	4
B	4	4
			C	8	4
D	12	8
			F	20	4
E	24	4

Further, optionally, in a specific implementation manner, when the software parameters included in each software parameter of the target software before updating are not included in each software parameter of the target software after updating, the data storage method provided by the embodiment of the present invention may further include the following steps:

wherein the third software parameters are: the pre-update target software includes software parameters that are not included in the post-update target software.

In addition, it can be understood that, in the use process after the target software updating is completed, the user can modify the parameter values of each software parameter according to the actual application scenario of the electronic device.

Based on this, in an optional implementation manner, as shown in fig. 7, after the step S106 is performed, the data storage method provided in the embodiment of the present invention may further include the following steps:

s109: obtaining a parameter updating instruction, wherein the parameter updating instruction comprises: the parameter value of the appointed parameter to be updated and the target parameter identification;

s110: and updating the parameter value corresponding to the target parameter identifier stored in the storage area into the parameter value of the parameter to be updated.

The configuration management module may detect whether a parameter update instruction is received, where the parameter update instruction may be sent by a user, or may be preset and automatically generated by an electronic device according to a certain period, and the parameter update instruction may include: the parameter value of the designated parameter to be updated and the target parameter identification.

The parameter value of the parameter to be updated and the target parameter identifier may be specified by a user, or may be specified when the electronic device automatically generates the parameter update instruction.

Furthermore, the configuration management module can directly determine the parameter value corresponding to the target parameter identifier from the parameter values of the binary software parameters stored in the preset storage area, and then the configuration management module can update the parameter value corresponding to the target parameter identifier into the acquired parameter value of the parameter to be updated.

When the parameter updating instruction is sent by the user, the user can specify the parameter value of the parameter to be updated and the target parameter identifier to the configuration management module through various modes such as drop-down menu clicking, input in a preset area and the like. The embodiment of the present invention is not particularly limited in this regard.

Further, the configuration management module may execute the above steps S109-S110 when detecting the operation of the user to specify the parameter value of the parameter to be updated and the target parameter identification.

It should be noted that, in the embodiment shown in fig. 5, after the step S108 is performed, the configuration management module may further perform the steps S109-S110.

In addition, for the target software that is installed for the first time and has never been updated, the configuration management module may also modify the parameter values of the respective software parameters of the target software according to the above steps S109-S110, which is reasonable.
