Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
At present, a parameter processing method for an electric power terminal generally comprises the following steps:
an external storage unit and a memory are arranged in the power terminal, wherein a parameter file is created in the external storage unit through a file system, and meanwhile a parameter backup is performed in the memory. When the parameters are to be changed, i.e. the parameters are to be added, deleted and modified, the backup parameters in the memory are changed first, and when all the parameters to be changed are modified in the memory, the backup parameters in the memory are integrally synchronized to the external storage unit. Although the scheme can change the parameters, the practical application has the problem of relatively large memory overhead, and the memory overhead is increased along with the increase of the types of the parameters, and the execution efficiency is low. Meanwhile, for the power terminal, all the parameters exist together, and the quantity of the parameters is large, so that the readability of the parameters is poor.
For example, in the conventional parameter processing scheme, when parameters need to be changed, for example, voltage parameters and current parameters need to be changed, after the data are changed in a memory, the entire data are synchronized to be stored outside, and each time data synchronization is performed, additional data, such as a terminal address, needs to be carried, so that each time parameter is changed, some important and difficultly-changed parameters need to be repeatedly stored, and when the parameter is used, the parameter is synchronized to an external storage unit after the parameter is changed, some difficultly-changed data are repeatedly stored in the memory, which causes the problems of high memory overhead and low execution efficiency.
First embodiment
Based on the problems of the prior art regarding the processing method of the parameters, the present application provides a new parameter processing method, which is applied to the controller 110 of the power terminal 100, wherein, referring to fig. 1, the power terminal 100 further includes a parameter backup unit 130 and a plurality of parameter storage units 120, each parameter storage unit 120 is connected to the parameter backup unit 130, the controller 110 is respectively connected to the parameter backup unit 130 and the plurality of parameter storage units 120, and each parameter storage unit 120 is used for storing different types of data. By the parameter processing method, the execution efficiency can be effectively improved in the parameter processing process, and meanwhile, the cost of the memory can be reduced in the parameter processing process.
As a possible implementation manner of the present application, please refer to fig. 2, a parameter processing method provided by the present application includes:
s102, a target parameter changing instruction is received, wherein the target parameter changing instruction comprises a target parameter to be changed.
When modification operations such as addition, deletion, and modification of parameters are required, a target parameter modification instruction needs to be sent to the power terminal 100 by a user, for example, the power terminal 100 is in communication connection with a server, and the user can send a target parameter modification quality to the power terminal 100 through the server.
In addition, the target parameter change instruction at least includes a target parameter to be changed, that is, a target parameter to be changed, for example, the target parameter to be changed is current information, voltage information, or the like.
S104, determining the type of the target parameter to be changed according to the target parameter to be changed and a preset parameter configuration table, wherein the preset parameter configuration table comprises the corresponding relation between the target parameter to be changed and the parameter type.
As an implementation manner of the present application, the power terminal 100 further includes a signal receiving unit, which is electrically connected to the controller 110, and is configured to receive the target parameter changing instruction and transmit the target parameter changing instruction to the controller 110 after receiving the target parameter changing instruction.
In the present application, a parameter configuration table is pre-stored in the controller 110, and the parameter configuration table includes a corresponding relationship between parameters and parameter types, for example, the voltage information belongs to a first type of parameter, the address information belongs to a second type of parameter, and the like. When the controller 110 receives the target parameter changing instruction, the type of the target parameter to be changed can be determined from the parameter configuration table according to the target parameter to be changed carried by the target parameter changing instruction.
S106, determining a target parameter storage unit according to the type of the target parameter to be changed, and changing the target parameter stored in the target parameter storage unit according to the target parameter changing instruction.
Since different parameter storage units 120 are used for storing different types of parameters, when the controller 110 determines the type of the target parameter to be changed, the target parameter storage unit 120 storing the type of parameter can be correspondingly determined, and then the target parameter stored in the target parameter storage unit 120 is changed. For example, the target parameter is voltage information, and the voltage information is stored in the target parameter storage unit 120, and the value of the voltage information stored at this time is 210V. At this time, the worker needs to modify the value of the voltage information to 220V, the content of the target parameter modification instruction may be "the voltage information is modified to 220V", when the controller 110 determines the type of the voltage information according to the upper voltage information, the target parameter storage unit 120 storing the voltage information may be determined, then the voltage information stored in the target parameter storage unit 120 is modified to 220V, and further, the modification of the parameters is completed quickly. Similarly, the addition or deletion of the parameter can be achieved in the same manner.
And S108, synchronizing the changed target parameters into a parameter backup unit for backup.
When the target parameter is modified, the controller 110 further controls the target parameter storage unit 120 to send the modified target parameter to the parameter backup unit 130 for backup.
It should be noted that, in the present application, the controller 110 only controls the modified parameters to be sent to the parameter backup unit 130 for backup, and for the unmodified parameters, since the parameters are already backed up in the parameter backup unit 130, it is not necessary to send the data to the parameter backup unit 130 again, so that the parameters stored in the parameter backup unit 130 are always the modified parameters, and the overhead of the memory is effectively reduced.
As a possible implementation manner, the plurality of parameter storage units 120 includes a first parameter storage unit, a second parameter storage unit, and a third parameter storage unit, where the first storage unit is used to store a first type of data, the second storage unit is used to store a second type of data, and the third storage unit is used to store a third type of data. The parameters are classified into three categories, and of course, in other embodiments, the parameters may be classified into more categories, which is not limited in this application.
Namely, S106 includes:
s106-1, when the type of the target parameter to be changed is the first type of parameter, determining that the first parameter storage unit is the target parameter storage unit.
S106-2, when the type of the target parameter to be changed is the second type parameter, determining that the second parameter storage unit is the target parameter storage unit.
S106-3, when the type of the target parameter to be changed is the third type parameter, determining that the third parameter storage unit is the target parameter storage unit.
After the type of the target parameter is determined through control, the target parameter storage unit can be correspondingly determined.
Further, as an implementation manner, the first parameter storage unit is a database, the second parameter storage unit is an rsv file, and the third parameter storage unit is a self file, and the parameters of the power terminal 100 are divided into the common parameters and the important parameters, and the important parameters are divided into the important parameters that are easy to change and the important parameters that are not easy to change. The database is used for storing common parameters, such as voltage information, current information and the like; rsv files are used to store important parameters that are subject to variation, such as communication parameters; the self file is used for storing important parameters which are not easy to change, such as terminal addresses.
In this implementation, S106 may specifically include:
s106-a, when the type of the target parameter to be changed is the common parameter, determining the database as a target parameter storage unit.
And S106-b, when the type of the target parameter to be changed is the variable important parameter, determining rsv the file as a target parameter storage unit.
And S106-c, when the type of the target parameter to be changed is an important parameter which is not easy to change, determining the self file as a target parameter storage unit.
Through adopting the mode of database and two unifications of file, realized the categorised storage to the parameter, on the one hand, through setting up different parameter memory cell 120, can carry out real-time processing to the parameter, can realize saving the parameter in database, rsv file or self file in real time, do not need other transfer operations, the executive efficiency who makes is high. In the second aspect, the readability of the parameters is better by classifying and storing the parameters, the parameters to be changed can be quickly positioned, and the time for positioning the parameters is saved. In the third aspect, important parameters are put into the rsv file and the self file, so that the operation of the power terminal 100 is more stable, and meanwhile, by classifying and storing the parameters, even if one of the parameters is damaged, all types of parameters are not damaged, and the safety of data storage is further improved.
Moreover, it should be noted that the csv file is distributed and stored according to the number of bytes occupied by each parameter in a parameter structure storage manner, has good intuitiveness in comparison with a binary storage manner of a database db file, supports direct modification, and can be consistent with parameters of an SDK (Software Development Kit) layer during compiling.
Meanwhile, in order to enable a worker to visually see the contents stored in the database, the power terminal 100 is installed with a system conversion tool to convert the data stored in the rsv file and the parameters stored in the database to each other. As an implementation mode, the system conversion tools are csv2db and db2csv tools, and the mutual conversion between the parameters stored in the database and the csv file storage parameters is realized, namely the storage parameters in the database are converted into 16 systems, or the 16 systems stored in rsv files are converted into binary parameters, so that the use of the parameters of an application layer and an SDK layer is realized, the effect of visually showing the database through the csv files is achieved, and the database form which is convenient to modify and compatible with the Linux system identification is realized.
Furthermore, the rsv file provided by the application can also be used for distinguishing types, regions, protocol type parameters and the like of different products, one set of codes can be used for distinguishing different region requirements, and the number of code versions is reduced. That is, codes suitable for a plurality of regions are integrated and stored in the rsv file. It will be appreciated that the code for each region has a fixed number, for example, code number 1 is a version of the code suitable for Beijing and code number 2 is a version of the code suitable for Jiangsu. Therefore, the rsv file is utilized to achieve the effects of really realizing the concepts of function configuration and generalization, reducing the maintenance amount and improving the working efficiency. For example, after the power terminal 100 is installed in beijing, a user may send a code version selection instruction to the power terminal 100, that is, only the code with the number 1 needs to be selected to implement the configuration of the power terminal 100 in beijing area, and it is not necessary to separately develop a single version corresponding to the area, thereby improving the work efficiency.
On the basis of the above implementation, the implementation manner of S102 includes three manners.
Firstly, the target parameter change instruction is sent and received in a message form, in this implementation manner, communication connection is implemented between the server and the power terminal 100, and the parameter change is implemented in a message form sent to the power terminal 100 by a server lamp. For example, the modification of the parameters in the database and rsv files is realized in the form of messages. Meanwhile, it should be noted that the parameters are modified in the form of a message, which is generally a single parameter.
Secondly, parameters in the database are directly modified, which may be in a remote form or in a field form, for example, at the site of the power terminal 100, a certain part of one parameter in the database is directly modified through the xShell background, so that the parameter modification is more efficient.
Thirdly, the parameters are modified through the liquid crystal on the power terminal 100, that is, the power terminal 100 is provided with a key, and through the content displayed on the liquid crystal, a user can select a certain parameter through a case, so as to further modify the parameter. Of course, the liquid crystal of the power terminal 100 may also be provided as a touch screen, which is not limited in this application.
On the basis of S104, please refer to fig. 3 as a possible implementation manner of the present application, where S104 includes:
s104-1, determining the type of the target parameter according to the identification code of the target parameter and a preset parameter configuration table; the parameter configuration table comprises the corresponding relation between the identification code and the parameter type.
Wherein each parameter stored by the power terminal 100 is provided with an identification code that can be used to determine the type of parameter. For example, the identification code of the parameter may be a, b, c, etc. representation that can be easily distinguished. Similarly, the target parameter is also provided with an identification code.
Meanwhile, the parameter configuration table pre-stored in the controller 110 actually includes a corresponding relationship between the identification code and the parameter type, for example, the parameter type corresponding to the parameter with the identification code a in the parameter configuration table is a common parameter, the parameter type corresponding to the parameter with the identification code b is an important parameter which is easy to change, the parameter type corresponding to the parameter with the identification code c is an important parameter which is not easy to change, and the type of the target parameter can be determined through the parameter configuration table and the identification code of the target parameter.
Since the number of parameters is large in practical use, the common parameters, the important parameters that are easy to change, and the important parameters that are not easy to change may include tens or hundreds of parameters, and thus, the time required for response is long when the parameters are determined.
Therefore, referring to fig. 4, as a possible implementation manner of the present application, S104-1 may include:
s104-2, determining the intermediate category of the target parameter according to the identification code of the target parameter and the parameter configuration table.
S104-3, determining the type of the target parameter according to the intermediate class to which the target parameter belongs and the parameter configuration table; the parameter configuration table comprises the corresponding relation between the identification code and the middle type and the corresponding relation between the middle type and the parameter type.
I.e. the common parameters, the important parameters which are easy to change and the important parameters which are not easy to change all comprise a plurality of intermediate categories, and each intermediate category corresponds to a plurality of identification codes, for example, for the common parameters, the intermediate categories comprise intermediate categories a1, a2 and A3, and the identification codes corresponding to a1 comprise a1, a2 and A3. At this time, if the target parameter is voltage information and the indication code corresponding to the voltage information is a1, the intermediate type to which the target parameter belongs can be determined to be a1 according to the identification code of the target parameter and the parameter configuration table, and meanwhile, the type of the target parameter can be determined according to the intermediate type to which the target parameter belongs and the parameter configuration table, so that the type of the target parameter can be determined more quickly.
As an implementation manner of the present application, the identifier of the parameter is an OAD, the controller 110 searches and determines which kind of parameter is in the parameter configuration table, if the parameter is a common parameter, the parameter is stored in the database according to the size sequence of the OAD, and the operations such as adding, deleting, modifying, and checking the parameter are performed according to the OAD.
Moreover, in order to ensure the correctness when reading the parameters, the present application further stores the corresponding parameters according to the JSON syntax, please refer to fig. 5, and the parameter processing method further includes:
s110, receiving a target parameter reading instruction, where the target parameter reading instruction includes bytes of a target parameter to be read.
S112, when the parameter in any one of the parameter storage units is read according to the target parameter reading instruction, the byte of the read target parameter is obtained.
S114, when the bytes of the read target parameters are not equal to the bytes of the target parameters to be read, the failure of reading the parameters is judged.
When the parameter in the parameter storage unit 120 needs to be read, a target parameter reading instruction needs to be sent to the power terminal 100 through a server or the like first, for example, when the voltage information needs to be read, then the target parameter reading instruction includes bytes of the voltage parameter that needs to be read.
And after receiving the parameter reading instruction, the controller 110 reads the parameters in the corresponding one or more parameter storage units 120 according to the parameter reading instruction, for example, when only the voltage information needs to be read, the controller 110 only needs to read the parameters of the voltage information in the database and simultaneously obtains the bytes of the read voltage information.
When the bytes of the obtained target parameters are not equal to the bytes of the target parameters to be read, the JSON syntax is incorrect, and at this time, the controller 110 determines that reading the parameters fails and cannot read the parameters. For example, the byte of the voltage information is 4 bytes, but the byte read by the controller 110 is 3 bytes, which indicates that misreading may occur at this time, and the controller 110 determines that reading fails, thereby effectively ensuring the correctness when reading the parameter.
Meanwhile, the present application can implement not only the backup of parameters, but also the restoration of parameters, and when the database, rsv file or self file is damaged, the user may send a synchronization instruction to the power terminal 100, and when the controller 110 receives the synchronization instruction, the data stored in the parameter backup unit 130 may be sent to the one or more parameter storage units 120.
For example, a shell script may be written, a fbak may be input to xShell to implement parameter backup, and when a parameter initialization operation is performed, a parameter initial value is obtained from a backup parameter through a parameter path, so that the parameter backup unit 130 and the parameter storage unit 120 are synchronized.
Second embodiment
Referring to fig. 1 again, an embodiment of the present application further provides an electric power terminal 100, where the electric power terminal 100 includes a controller 110, a parameter backup unit 130, and a plurality of parameter storage units 120, the controller 110 is respectively connected to the parameter backup unit 130 and the plurality of parameter storage units 120, each parameter storage unit 120 is connected to the parameter backup unit 130, and each parameter storage unit 120 is used for storing different types of data.
The controller 110 is configured to receive a target parameter modification instruction, where the target parameter modification instruction includes a target parameter to be modified.
The controller 110 is further configured to determine the type of the target parameter to be changed according to the target parameter to be changed and a preset parameter configuration table, where the preset parameter configuration table includes a corresponding relationship between the target parameter to be changed and the parameter type.
The controller 110 is further configured to determine the target parameter storage unit 120 according to the type of the target parameter to be changed, and change the target parameter stored in the target parameter storage unit 120 according to the target parameter change instruction.
The parameter storage unit 120 is configured to synchronize the changed target parameter to the parameter backup unit 130 for backup.
And, in order to protect the security of the parameters, the parameters stored in the power terminal 100 are all correspondingly provided with security codes, and it can be understood that the target parameters stored in the target parameter storage unit 120 are also provided with security codes, and when the target parameters are changed, the security codes are correspondingly changed, so that it can be determined whether the parameters have been changed according to the security codes. For example, when the security code of the voltage information is stored as X, when the voltage information is read, if the security code of the voltage information is X, it indicates that the voltage information has not been changed; when the voltage information is read, if the security code of the voltage information is Y, it indicates that the voltage information has been modified, thereby implementing the detection of the parameter security of the power terminal 100.
As one implementation way of the application, the application uses the md5 method to ensure the correctness of the important parameter, namely the security code is the md5 value. When the parameters are normally operated, the md5 values are updated in real time, if the parameters are changed due to illegal operation, the md5 values are inconsistent, the operation is illegal, and the reliability of the parameters is further ensured.
In summary, the present application provides a parameter processing method and an electric power terminal, wherein the parameter processing method is applied to a processor of the electric power terminal, the electric power terminal further includes a parameter backup unit and a plurality of parameter storage units, each parameter storage unit is connected with the parameter backup unit, the controller is respectively connected with the parameter backup unit and the plurality of parameter storage units, and each parameter storage unit is used for storing different types of data. The method comprises the steps of receiving a target parameter changing instruction, determining the type of a target parameter to be changed according to the target parameter to be changed and a preset parameter configuration table, determining a target parameter storage unit according to the type of the target parameter to be changed, changing the target parameter stored in the target parameter storage unit according to the target parameter changing instruction, and finally synchronizing the changed target parameter to a parameter backup unit for backup. On one hand, the parameters are directly changed in the parameter storage unit, and then the changed parameters are backed up to the parameter backup unit, so that the parameters can be changed without waiting, and the execution efficiency is higher. On the other hand, because the parameters are classified, only the changed parameters need to be backed up, and data which is not changed does not need to be backed up, so that the memory overhead of the parameter backup unit is effectively reduced.
Although the present invention is disclosed above, the present invention is not limited thereto. Various changes and modifications may be effected therein by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
