Description

Technical Field

[0001] The present invention relates to the field of parameter configuration, and in particular to a parameter configuration method, device, equipment, medium and product. Background Art

[0002] In the embedded field, configuring system functions by loading parameters has become the mainstream, with the purpose of improving the versatility of software. However, with the emergence of this configuration mode, parameter support for configurability has also become a rigid requirement of the system. The existing technology generally requires the use of a specified method (such as a matching host computer or communication interface, communication method, etc.) to configure system parameters. The reason is that the specified method is pre-configured with an authentication module. For example, the customer first enters the user name and password through the matching host computer, and then configures the system parameters after the authentication module authenticates the user name and password. However, the customer may not be able to use the specified method to configure the system parameters due to constraints such as the on-site installation form and the customer system topology design.

[0003] Furthermore, the prior art generally configures parameters and corresponding configuration information directly in the parameter configuration file, but this will cause strong coupling between the parameters and the configuration information. At this time, if you want to modify the parameters corresponding to the configuration information, you need to modify the parameter configuration file accordingly. The system operation depends on the parameter configuration file, and multiple modifications can easily lead to system instability.

[0004] Therefore, in the process of implementing the present invention, the inventors found that the prior art has at least the following problems: 1. The prior art is not compatible with more application scenarios to realize the configuration of system parameters; 2. The prior art needs to modify the parameter configuration file when modifying the parameters corresponding to the configuration information, which easily leads to system instability. Summary of the invention

[0005] In view of this, the purpose of the present invention is to provide a parameter configuration method, device, equipment, medium and product, which can use the security constraints pre-configured in the parameter configuration file to make security constraints on the configuration behavior of the parameters, so as to be compatible with more application scenarios; and introduce logical addresses to weaken the direct relationship between parameters and configuration information, so that the parameters corresponding to the configuration information can be modified by only modifying the corresponding relationship between the parameters and the logical addresses.

[0019] Optionally, the parameter configuration method further includes:

[0020] When the current parameter configuration file is determined based on the backup file of the original parameter configuration file, the original parameter configuration file and the current parameter configuration file are respectively stored in different storage areas in the preset system.

[0021] Optionally, determining the current parameter configuration file based on the backup file of the original parameter configuration file includes:

[0022] Determining target group configuration information from an original parameter configuration file according to the attribute information; wherein the attribute information includes parameter preservation attributes;

[0023] The target group configuration information is backed up to obtain a backup file, and a current parameter configuration file is determined based on the backup file.

[0024] Optionally, after updating the current parameter configuration file, the method further includes:

[0025] The preset system is controlled to continue to operate based on the updated current parameter configuration file.

[0026] Optionally, the parameter configuration method further includes:

[0027] When the preset system is started for the first time, controlling the preset system to start running based on the original parameter configuration file;

[0050] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0051] In the process of implementing the present invention, the inventors found that the prior art has at least the following problems: 1. The prior art is not compatible with more application scenarios to realize the configuration of system parameters; 2. The prior art needs to modify the parameter configuration file when modifying the parameters corresponding to the configuration information, which easily leads to system instability. To this end, the present application provides a parameter configuration method, which makes security constraints on the configuration behavior of the parameters by utilizing the security constraints pre-configured in the parameter configuration file, so as to be compatible with more application scenarios; and introduces logical addresses to weaken the direct relationship between parameters and configuration information, so that the modification of the parameters corresponding to the configuration information is realized when only the corresponding relationship between the parameters and the logical addresses needs to be modified, thereby improving the stability of the system.

[0052] See also Figure 1 As shown, an embodiment of the present invention discloses a parameter configuration method, including:

[0053] Step S11: Obtain a parameter configuration request initiated for a target parameter.

[0054] In this embodiment, during the operation of the preset system, a parameter configuration request initiated for the target parameter is obtained through the preset system. The preset system can obtain the parameter configuration request sent by the host computer or communication interface supporting the preset system, or the parameter configuration request sent by the external interface, which can be a customer-defined communication interface.

[0055] It should be noted that the application subject of the parameter configuration method proposed in this embodiment is a preset system. The preset system may be a computer system, such as an embedded system. In addition, in this embodiment, a parameter management system may be set in the preset system to respond to the parameter configuration request through the parameter management system, thereby realizing parameter configuration.

[0056] Step S12: Determine the security constraint condition corresponding to the target logical address from the current parameter configuration file; the target logical address is the logical address corresponding to the target parameter.

[0057] In this embodiment, before determining the security constraints corresponding to the target logical address from the current parameter configuration file, it is necessary to first determine the current parameter configuration file based on the original parameter configuration file. Then, when a parameter configuration request initiated for the target parameter is obtained, the corresponding security constraints can be determined from the current parameter configuration file based on the target logical address corresponding to the target parameter.

[0058] Among them, the original parameter configuration file is a file pre-stored in the preset system. The original parameter configuration file can support the initial startup and operation of the preset system, and when an abnormality occurs in the preset system, the preset system can be restored based on the original parameter configuration file to restore the parameters in the preset system to the default values.

[0059] Furthermore, at least one set of configuration information is pre-configured in the original parameter configuration file, and each set of configuration information includes a logical address corresponding to a parameter and attribute information and security constraints corresponding to the logical address. That is, the original parameter configuration file includes at least one set of configuration information based on the logical address, attribute information, and security constraints, wherein the logical address is a unique identifier for each set of configuration information in the original parameter configuration file, and different logical addresses correspond to different parameters.

[0060] Since the logical address corresponds to the parameter and the attribute information corresponds to the logical address, the attribute information corresponding to the logical address can also be understood as the attribute information corresponding to the parameter, that is, the attribute information represents the attribute information of the parameter. Moreover, different logical addresses correspond to different attribute information, which means that different parameters correspond to different attribute information.

[0061] The attribute information includes but is not limited to parameter type, parameter saving attribute and parameter default value; wherein, parameter type includes signed number (signed) and unsigned number (unsigned), for example, S16 represents a 16-bit signed number, and U32 represents a 32-bit unsigned number; parameter saving attributes include power-off saving, permanent saving and not saving.

[0062] Since the logical address corresponds to the parameter and the security constraint corresponds to the logical address, the security constraint corresponding to the logical address can also be understood as the security constraint corresponding to the parameter, that is, the security constraint represents the security constraint of the parameter. Moreover, different logical addresses correspond to different security constraints, which means that different parameters correspond to different security constraints.

[0063] The security constraints include but are not limited to the first constraint and the second constraint. The first constraint is that the value of the parameter to be configured corresponding to the parameter configuration request is within the preset parameter value range, that is, the preset parameter value range is used to constrain the configurable range of the parameter. If the value of the parameter to be configured corresponding to the parameter configuration request is not within the preset parameter value range, the default value of the parameter is not allowed to be modified. The second constraint is that the access permission level corresponding to the parameter configuration request reaches the preset access permission level, that is, the preset access permission level is used to constrain whether there is permission to configure the attribute information of the parameter. If the access permission level corresponding to the parameter configuration request does not reach the preset access permission level, it indicates that there is no permission to configure the attribute information of the parameter.

[0064] by Figure 2 Take the parameter configuration file shown as an example, the parameter configuration file includes three groups of configuration information. The first group of configuration information has a logical address of 0, a parameter type of S16 (16-bit signed number), a parameter saving attribute of power-off saving, a parameter default value of 100, a preset parameter value range of [0, 1000], and a preset access right level of level 1; the second group of configuration information has a logical address of 1, a parameter type of U16 (16-bit unsigned number), a parameter saving attribute of permanent saving, a parameter default value of 0, a preset parameter value range of [0, 2000], and a preset access right level of level 2; the third group of configuration information has a logical address of 2, a parameter type of U32 (32-bit unsigned number), a parameter saving attribute of not saving, a parameter default value of 300, a preset parameter value range of [0, 3000], and a preset access right level of level 3. Whether the access right level is level 1 < level 2 < level 3, or level 1 > level 2 > level 3, it can be set according to the system development requirements.

[0065] In this embodiment, for determining the current parameter configuration file based on the original parameter configuration file, one way is to determine the original parameter configuration file as the current parameter configuration file; another way is to determine the current parameter configuration file based on a backup file of the original parameter configuration file.

[0066] It should be noted that determining the original parameter configuration file as the current parameter configuration file can save a certain amount of storage space, while determining the current parameter configuration file based on the backup file of the original parameter configuration file can retain the original parameter configuration file so that the system can be restored based on the original parameter configuration file when an abnormality occurs in the preset system. Both methods support parameter configuration based on the current parameter configuration file, and use security constraints to impose security constraints on the configuration behavior of parameters, so as to be compatible with more application scenarios, improve the security of parameter configuration, and support parameter configuration in more application scenarios.

[0067] When the current parameter configuration file is determined based on the backup file of the original parameter configuration file, the original parameter configuration file and the current parameter configuration file are respectively stored in different storage areas in the preset system, that is, the original parameter configuration file and the current parameter configuration file are stored in different storage areas in the preset system. For example, the original parameter configuration file is stored in the first storage area in the preset system, and the current parameter configuration file determined based on the backup file of the original parameter configuration file is stored in the second storage area in the preset system.

[0068] When determining the original parameter configuration file as the current parameter configuration file, only one storage area is required, that is, the original parameter configuration file is stored in the first storage area in the preset system, and the original parameter configuration file stored in the first storage area is determined as the current parameter configuration file.

[0069] Specifically, in the process of determining the current parameter configuration file based on the backup file of the original parameter configuration file, it is necessary to first determine the target group configuration information from the original parameter configuration file based on the attribute information, back up the target group configuration information to obtain a backup file, and then determine the current parameter configuration file based on the backup file.

[0070] Exemplarily, the target group configuration information is determined from the original parameter configuration file according to the parameter preservation attribute; wherein the parameter preservation attribute can be any one or a combination of power-off preservation, permanent preservation, and non-preservation. Figure 2 For example, assuming that the target group configuration information is determined from the original parameter configuration file according to power-off preservation and permanent preservation, the target group configuration information at this time includes the first group configuration information and the second group configuration information.

[0071] Exemplarily, the target group configuration information is determined from the original parameter configuration file according to the parameter type; wherein the parameter type can be a signed number and / or an unsigned number. Figure 2 For example, assume that the target group configuration information is determined from the original parameter configuration file according to a signed number, and the target group configuration information at this time includes the first group configuration information.

[0072] Furthermore, before determining the security constraint corresponding to the target logical address from the current parameter configuration file, the present embodiment needs to determine the target logical address first. Specifically, after obtaining the parameter configuration request initiated for the target parameter, the parameter configuration request is parsed to obtain the target parameter and determine the target logical address corresponding to the target parameter.

[0073] More specifically, the physical memory address corresponding to the target parameter is first determined from the preset memory distribution table, and then the target logical address corresponding to the physical memory address is determined based on the preset mapping relationship. The preset memory distribution table is used to record the parameters corresponding to each physical memory address, that is, the preset memory distribution table records the specific parameter meaning of each physical memory address; the preset mapping relationship is used to record the mapping relationship between the physical memory address and the logical address; and the physical memory address in this embodiment can refer to either a physical memory address or a physical memory address segment composed of multiple physical memory addresses.

[0074] Considering that if the parameters and the corresponding configuration information are directly coupled together in the parameter configuration file, when modifying the parameters corresponding to the configuration information, the parameter configuration file must be modified accordingly, but the parameter configuration file is a file that supports the operation of the system, and multiple modifications are likely to cause system instability. Therefore, this embodiment uses the memory mapping principle to utilize the mapping relationship between the logical address and the physical memory address to weaken the strong coupling between the parameters and the configuration information, so that the parameters corresponding to the configuration information can be modified by only modifying the parameters corresponding to the physical memory address without modifying the parameter configuration file.

[0075] Specifically, this embodiment records the parameters corresponding to each physical memory address through a preset memory distribution table, and records the configuration information (attribute information and security constraints) corresponding to each logical address through a parameter configuration file, and the preset mapping relationship records the mapping relationship between the physical memory address and the logical address. Therefore, this embodiment only needs to modify the parameters corresponding to the physical memory address in the preset memory distribution table, that is, modify the specific parameter meaning of the physical memory address, and the parameters corresponding to the configuration information in the parameter configuration file can be modified through the preset mapping relationship.

[0076] like Figure 3 As shown, Figure 3The mapping diagram of the memory distribution table and the parameter configuration file is shown, wherein in the memory distribution table, the physical memory address 0x10000000-0x10000001 corresponds to the cooling set point, the physical memory address 0x10000002-0x10000003 corresponds to the accumulated running time, and the physical memory address 0x10000004-0x10000007 corresponds to the authentication tag. The parameter configuration file includes three groups of configuration information, the first group of configuration information includes logical address 0 and corresponding configuration information 0, the second group of configuration information includes logical address 1 and corresponding configuration information 1, and the third group of configuration information includes logical address 2 and corresponding configuration information 2. In the preset mapping relationship, physical memory address 0x10000000-0x10000001 corresponds to logical address 0, physical memory address 0x10000002-0x10000003 corresponds to logical address 1, and physical memory address 0x10000004-0x10000007 corresponds to logical address 2. At this time, configuration information 0 corresponds to the cooling set point, configuration information 1 corresponds to the accumulated running time, and configuration information 2 corresponds to the authentication tag.

[0077] If you want to change the parameters corresponding to configuration information 0 from the cooling set point to the heating set point, you only need to change the parameters corresponding to the physical memory address 0x10000000-0x10000001 from the cooling set point to the heating set point. At this time, since the physical memory address 0x10000000-0x10000001 corresponds to the logical address 0, and the logical address 0 corresponds to the configuration information 0, the modification of the parameters corresponding to the configuration information 0 can be completed by using the memory mapping principle.

[0078] Step S13: Based on the parameter configuration request that satisfies the security constraint condition, configure the attribute information corresponding to the target logical address in the current parameter configuration file to update the current parameter configuration file.

[0079] In this embodiment, after determining the security constraint corresponding to the target logical address from the current parameter configuration file, the parameter configuration request is verified using the security constraint to determine whether the parameter configuration request satisfies the security constraint. If the parameter configuration request does not satisfy the security constraint, the attribute information corresponding to the target logical address in the current parameter configuration file is not allowed to be configured. If the parameter configuration request satisfies the security constraint, the attribute information corresponding to the target logical address in the current parameter configuration file is configured based on the parameter configuration request that satisfies the security constraint, thereby updating the current parameter configuration file.

[0080] The security constraint condition includes a first constraint condition and / or a second constraint condition; the first constraint condition is that the parameter value to be configured corresponding to the parameter configuration request is within a preset parameter value range; the second constraint condition is that the access permission level corresponding to the parameter configuration request reaches the preset access permission level. In this way, this embodiment pre-configures the security constraint condition in the parameter configuration file, so that when the parameter configuration needs to be modified, the security constraint condition is used to constrain the parameter configuration behavior, thereby preventing the parameters from being accidentally modified or tampered with, thereby improving the security of the parameter configuration.

[0081] For example, Figure 2 As shown, if the security constraints corresponding to the target logical address in the current parameter configuration file include a first constraint and a second constraint, then when the parameter value to be configured corresponding to the parameter configuration request is within the preset parameter value range, and the access permission level corresponding to the parameter configuration request reaches the preset access permission level, the parameter default value corresponding to the target logical address in the current parameter configuration file is modified using the parameter value to be configured to update the current parameter configuration file.

[0082] For example, Figure 2 As shown, if the security constraint conditions corresponding to the target logical address in the current parameter configuration file include the first constraint condition, then when the parameter value to be configured corresponding to the parameter configuration request is within the preset parameter value range, no matter what level of access permission corresponding to the parameter configuration request is, the parameter default value corresponding to the target logical address in the current parameter configuration file can be modified using the parameter value to be configured to update the current parameter configuration file.

[0083] For example, Figure 2 As shown, if the security constraints corresponding to the target logical address in the current parameter configuration file include the second constraint, then when the access permission level corresponding to the parameter configuration request reaches the preset access permission level, the parameter saving properties corresponding to the target logical address in the current parameter configuration file are modified using the parameter saving properties to be configured corresponding to the parameter configuration request to update the current parameter configuration file.

[0084] Furthermore, after updating the current parameter configuration file, the present embodiment needs to control the preset system to continue to run based on the updated current parameter configuration file. In this way, the present embodiment can support the configurability of parameters during the system operation process to meet the user's use requirements for the system.

[0085] It should be noted that when the preset system is started for the first time, it is necessary to control the startup of the preset system based on the original parameter configuration file, that is, the startup of the preset system is controlled by the default parameter configuration or the original parameter configuration. When the preset system is powered off and restarted, it is necessary to control the startup of the preset system based on the latest current parameter configuration file, that is, the preset system restarted after power failure can be started with the parameter configuration before power failure, thereby restoring the preset system restarted after power failure to the system state before power failure, retaining the parameter configuration made by the user before power failure, and improving the user's system experience.

[0086] If the original parameter configuration file is updated, it is necessary to control the preset system to run again based on the updated original parameter configuration file, and redetermine the current parameter configuration file based on the updated original parameter configuration file. It should be noted that since the original parameter configuration file is the file that supports the initial startup and operation of the preset system and contains the original parameter configuration, when the original parameter configuration file is updated, it is necessary to control the preset system to run again based on the updated original parameter configuration file, and redetermine the current parameter configuration file.

[0087] Among them, the updating of the original parameter configuration file includes the target updating operation of the attribute information and / or the security constraint condition, and the target updating operation includes any one or more of adding, deleting and modifying. It can be found that this embodiment supports the adding, deleting and modifying of the attribute information and the security constraint condition through the original parameter configuration file, that is, supports the configuration configuration of the attribute information and the security constraint condition, so that the adding and deleting of the attribute information and the security constraint condition will not affect the operation of the system, and supports the extensibility of the attribute information and the security constraint condition.

[0088] It can be seen that this embodiment pre-configures the security constraint condition in the parameter configuration file, so that when the parameter configuration request is obtained, the parameter configuration request is verified by the security constraint condition, so as to make security constraints on the configuration behavior of the parameter by using the security constraint condition, so as to be compatible with more application scenarios, which not only improves the security of the parameter configuration, but also supports parameter configuration in more application scenarios. In addition, this embodiment associates the parameter with the logical address, and pre-configures the logical address corresponding to the parameter and the corresponding attribute information and security constraint condition in the parameter configuration file, so as to perform parameter configuration according to the relationship between the parameter and the logical address, the logical address and the attribute information and the security constraint condition. Compared with the prior art, this embodiment does not need to directly couple the parameter and the configuration information in the parameter configuration file, and weakens the direct relationship between the parameter and the configuration information, so as to achieve the modification of the parameter corresponding to the configuration information when only the corresponding relationship between the parameter and the logical address needs to be modified, and solves the problem that the direct modification of the parameter configuration file easily leads to system instability.

[0089] like Figure 4 As shown, taking the preset system as an embedded system, and the embedded system including a parameter management system and application software as an example, the parameter configuration method of the present application is described, and the specific scheme is as follows:

[0090] In the system preparation stage, the original parameter configuration file is stored in the first storage area of ​​the preset system, and the target group configuration information is determined from the original parameter configuration file according to the parameter preservation attribute (such as power-off preservation and permanent preservation), and the target group configuration information is backed up to determine the current parameter configuration file based on the backup file, and the current parameter configuration file is stored in the second storage area of ​​the preset system. Among them, the parameter configuration file includes the logical address corresponding to the parameter and the corresponding attribute information and security constraints, and the attribute information includes the parameter preservation attribute.

[0091] During the system operation phase, the parameter configuration request initiated for the target parameter is obtained through the application software, and the parameter configuration request is sent to the parameter management system. After the parameter management system obtains the parameter configuration request, the parameter configuration request is parsed to obtain the target parameter, and the physical memory address corresponding to the target parameter is determined from the preset memory distribution table, and the target logical address corresponding to the physical memory address is determined based on the preset mapping relationship, and then the security constraint condition corresponding to the target logical address is determined from the current parameter configuration file located in the second storage area.

[0092] The security constraints are parsed and executed through the parameter management system to determine whether the parameter configuration request satisfies the security constraints. If the security constraints are satisfied, the attribute information corresponding to the target logical address in the current parameter configuration file is configured based on the parameter configuration request to update the current parameter configuration file.

[0093] In addition, the parameter management system parses and executes the attribute information of each parameter in the current parameter configuration file, such as assigning the parameter default value to the corresponding parameter, performing a save operation on the corresponding parameter based on the parameter save attribute, etc. At the same time, the system application logic of each parameter is executed based on the current parameter configuration file by the application software to control the preset system operation.

[0094] It can be seen that this embodiment pre-configures the security constraint conditions in the parameter configuration file so that when the parameter configuration request is obtained, the parameter configuration request is verified by the security constraint conditions, thereby using the security constraint conditions to make security constraints on the configuration behavior of the parameters, so as to be compatible with more application scenarios, which not only improves the security of parameter configuration, but also supports parameter configuration in more application scenarios. In addition, this embodiment uses the mapping relationship between logical addresses and physical memory addresses to weaken the direct coupling relationship between parameters and configuration information (attribute information and security constraint conditions), so that without modifying the parameter configuration file, the parameters corresponding to the configuration information can be modified by only modifying the parameters corresponding to the physical memory address in the memory distribution table.

[0095] See also Figure 5 As shown, an embodiment of the present invention discloses a parameter configuration device, including:

[0096] A request acquisition module 11 is used to acquire a parameter configuration request initiated for a target parameter;

[0097] The constraint determination module 12 is used to determine the security constraint corresponding to the target logical address from the current parameter configuration file; the target logical address is the logical address corresponding to the target parameter;

[0098] The parameter configuration module 13 is used to configure the attribute information corresponding to the target logical address in the current parameter configuration file based on the parameter configuration request that meets the security constraint condition, so as to update the current parameter configuration file.

[0099] It can be seen that the present application pre-configures the security constraint conditions in the parameter configuration file, so that when the parameter configuration request is obtained, the parameter configuration request is verified by the security constraint conditions, so as to make security constraints on the configuration behavior of the parameters by using the security constraint conditions, so as to be compatible with more application scenarios, which not only improves the security of the parameter configuration, but also supports parameter configuration in more application scenarios. In addition, the present application associates the parameters with the logical addresses, and pre-configures the logical addresses corresponding to the parameters and the corresponding attribute information and security constraint conditions in the parameter configuration file, so as to perform parameter configuration according to the relationship between the parameters and the logical addresses, and between the logical addresses and the attribute information and the security constraint conditions. Compared with the prior art, the present application does not need to directly couple the parameters and the configuration information in the parameter configuration file, and weakens the direct relationship between the parameters and the configuration information, so as to achieve the modification of the parameters corresponding to the configuration information when only the corresponding relationship between the parameters and the logical addresses needs to be modified, and solves the problem that the direct modification of the parameter configuration file easily leads to system instability.
