The present embodiment provides a method for reading feature data, as shown in fig. 1, the method includes:
s100, when a preset application program is started, a preset configuration file is obtained.
In this embodiment, a feature data area dedicated to storing feature data is created in the system, a configuration file for describing the feature data area is placed in the system, and related logic related software is added to the system software to read and write the feature data according to the rules of the system software. Therefore, the universal configuration of the characteristic data of the customized televisions of different operators is realized, so that the special butt joint adaptation of the characteristic data of the customized televisions is avoided, the characteristic data of the television is invisible to other unused operators, the safety of the characteristic data of the operators is improved, and the adaptation work of manufacturers to the characteristic data of the customized televisions of the operators is avoided.
Further, the characteristic data area exists in a system software memory and cannot be lost in power failure, wherein the memory comprises but is not limited to Flash, EEPROM, EMMC and the like. In practical applications, the feature data area is not updated when the system is upgraded. Moreover, only specific software has the authority to operate, and other software can read related information only through the interface of the specific software, so that the safety of data can be ensured to the maximum extent. It should be noted that the specific software is the preset application program of the present invention. That is, the feature data area and the preset configuration file are visible only to the preset application program and are invisible to application programs other than the preset application program.
S200, analyzing the configuration file to obtain parameter information corresponding to the characteristic data.
Specifically, the parameter information is information stored in a characteristic data area; the profile is present along with the operator's need to customize the television, and if a machine that is not third party customized or named does not have this file, it is updated at the time of system upgrade, so that one machine can be swiped into a customization machine in some way. Further, the names of the configuration files on the same type of machine according to certain rule logic are the same, including but not limited to: using a fixed name; or from a combination of system-related attributes. In this embodiment, the configuration file is named by the identifier of the television and is stored in the preset path, that is, the configuration file named incorrectly or the configuration files of other paths cannot be correctly identified. Correspondingly, analyzing the configuration file to obtain the parameter information corresponding to the feature data specifically includes:
s201, judging whether a path corresponding to the preset configuration file meets a preset rule or not;
s202, when the path corresponding to the preset configuration file meets a preset rule, analyzing the configuration file to obtain parameter information corresponding to the characteristic data.
In this embodiment, after a preset configuration file is obtained, it is first determined whether a path corresponding to the preset configuration file meets a preset rule, and when the path corresponding to the preset configuration file meets the preset rule, the configuration file is analyzed to obtain parameter information corresponding to the feature data. For example, the configuration file generates a corresponding file path and a file name according to relevant parameters of an operator, for example, the operator configures a specific identifier (cmcc) for a mobile machine, and then can determine that the path of the configuration file is "/fac/cmcc/a" according to the identifier; another operator is a connected machine, whose specific identifier is (liantong), and then the path of the configuration file can be determined as "/fac/liantong/al according to the identifier, so that if the configuration file does not satisfy the path and the file naming rule, the configuration file cannot be parsed.
And S300, reading the feature data stored in the preset feature data area according to the preset application program and the parameter information.
Specifically, the interface corresponding to the preset application program includes a read feature data interface and a write feature data area interface. Correspondingly, reading the feature data stored in the preset feature data area according to the preset application program and the parameter information includes: reading the feature data stored in a preset feature data area according to the read feature data interface and the parameter information; it can be understood that, according to the preset application program and the parameter information, the reading of the feature data stored in the preset feature data area further includes a writing operation of the feature data, so that the method for reading the feature data further includes: writing the obtained feature data into a preset feature data area according to the preset application program and the attribute information, wherein the specific process may include: and writing the obtained characteristic data into the characteristic data area according to the written characteristic data interface and the parameter information.
In this embodiment, the feature data area and the preset configuration file are invisible to the application programs other than the preset application program. Illustratively, taking a certain third-party customizing machine as an example, the customizing machine needs to burn three feature data, and the third-party manufacturer names the three feature data to be SN (Length 15 bits), DID (Length 32 bits), and ProductInfo (Length 60 bits), and then generates a configuration file related to the third-party customizing machine according to the above information, such as thridkey. ini, the content of the file is shown in fig. 2, wherein data in "{ }" represents related information of one feature data, such as Key, indicating whether the current data is used (true is used and false is not used); the rules and contents stored according to the feature data of the specific area after the picture analysis are as follows: 1 to 15 bits of the specific area are used for storing 15 bits of characteristic data with the name of SN, and the analytic format of the specific area is hexadecimal analytic; 16 to 48 bits are used for storing 32 bits of feature data with the name of DID, and the analytic format of the feature data is 10-system; bits 49 through 109 are used to store feature data named ProductInfo, which is parsed into a string format.
Further, as shown in fig. 3, the data structure for customizing tv synthesis for the operator may be a software in the system for reading the feature data, parsing the file according to a predetermined rule to obtain the above information, and providing the following interfaces:
object getSpecialData (String dataName)// read feature data
Boolean setSpecialData (String dataName)// write feature data
Wherein, Object can represent the former types such as hexadecimal, decimal and character string, and it should be noted that this type is consistent with DataFormat in the configuration file.
Further, in an implementation manner of this embodiment, before reading the feature data stored in the preset feature data area according to the preset application program and the attribute information, the method further includes:
h1, determining target parameter information corresponding to the preset configuration file based on an interface corresponding to a preset application program;
h2, when the parameter information is consistent with the target parameter information, reading the feature data stored in a preset feature data area based on the interface corresponding to the preset application program and the parameter information.
In this embodiment, the names and data formats of the feature data are unknown to other applications that do not use the special data, so that the corresponding feature data cannot be acquired through the interface corresponding to the preset application, which increases the security of the feature data. Software using the feature data is needed, and only if the dataName and data parameters meet the rule defined by the configuration file (for example, the Length of the feature data before the Length is met), the application program reading and writing the feature data in the system returns normal data.
In summary, compared with the prior art, the embodiment of the invention has the following advantages:
the invention discloses a method for reading feature data, which comprises the following steps: when a preset application program is started, acquiring a preset configuration file; analyzing the configuration file to obtain parameter information corresponding to the characteristic data; and reading the feature data stored in a preset feature data area according to the preset application program and the parameter information.
