Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities.
In this example embodiment, first, a method for handover of coal mine underground data based on two-dimension codes is provided, referring to fig. 1, the method may include: step S101 to step S103. The method comprises the following steps:
step S101, a receiving end receives a two-dimensional code picture sent by a sending end, wherein the two-dimensional code picture is generated by the sending end after processing encoded data by using a two-dimensional code generating tool, and the encoded data are data with an original data format which need to be handed over. Before encoding at the sender, a writer is required to convert the original data report into a format suitable for encoding. This process requires consideration of the structure and size of the data and ensures that the encoded data is not lost or corrupted.
The two-dimensional code plays a key role as a data sharing medium. In practical application, a two-dimensional code generation library can be used for generating corresponding two-dimensional code pictures from the encoded data. The size and fault tolerance of the two-dimensional code need to be adjusted according to actual conditions so as to ensure stable analysis under different environments.
Step S102, a receiving end scans and analyzes the two-dimensional code picture by using a two-dimensional code scanning tool to restore data corresponding to the two-dimensional code picture into an original data format, wherein an inverse algorithm is adopted to analyze the scanned data of the two-dimensional code picture when the two-dimensional code picture is analyzed.
Step S103, the receiving end enters a data filling page to carry out data filling and submits filling data. The fill-in content may include entering text information, taking photographs or other necessary data records, etc.
In this embodiment, the two-dimensional code image is scanned to perform data reporting and handover, so that handover data with larger transmission quantity can be obtained; and analyzing the scanned data corresponding to the two-dimensional code picture by using a reverse algorithm, so that the data reduction processing is more stable, the acquired data is more complete, and errors are not easy to occur.
It should be noted that, in order to obtain a larger data transmission amount, the two-dimensional code picture includes a first layer two-dimensional code and a plurality of lower layer two-dimensional codes associated with the first layer two-dimensional code. And acquiring information carried in the two-dimensional codes by scanning the plurality of lower-layer two-dimensional codes, and performing data reduction.
On the basis of the above embodiment, please refer to fig. 2, in step S102, the step of the receiving end using a two-dimensional code scanning tool to scan and parse the two-dimensional code picture to restore the data corresponding to the two-dimensional code picture to the original data format includes:
step S201, a local database is preset for storing local data corresponding to the original data. The local data corresponding to the original data stored in the local database may be report elements or the like.
Step S202, setting a locator for the two-dimensional code picture, for linking to corresponding local data.
Step S203, when scanning the two-dimension code picture, the corresponding local data is obtained through the locator to complete data restoration.
In this embodiment, the two-dimensional code picture stores the locator, the locator is obtained by scanning the two-dimensional code picture, the target data corresponding to the locator is determined by the locator and the local data, and the target data corresponding to all the locators form the whole report, so as to complete data reduction.
In addition, the data reduction process may involve rearranging, organizing, and formatting the data to conform to the structure of the original data report. This ensures that the resulting data is consistent with the original report and can be understood and processed normally.
In some embodiments, referring to fig. 3, in step S102, the step of analyzing the scanned data of the two-dimensional code picture by using an inverse algorithm includes:
step S301, analyzing key information in the encoded characters of the two-dimensional code picture, where the key information includes a data structure and an encoding mode. The two-dimensional code data acquired by the scanning device is a string of encoded characters or numbers. The parsing program is responsible for decomposing these characters and identifying key information therein, such as the structure of data, the encoding scheme, etc., but is not limited thereto.
In step S302, the parsed data is processed by an inverse algorithm to obtain the data restored to the original data format, where the inverse algorithm includes data operation, logic operation and conversion rules. The data is parsed out and the inverse algorithm will begin processing the data. This algorithm may utilize a variety of mathematical operations, logical operations, and specific transformation rules, which may be predefined when the analysis program is being formulated. The main goal of the inverse algorithm is to restore the encoded or converted data to the original data reporting format. This can gradually cancel the previous encoding operations according to rules in the parsing program, and restore the original structure and content of the data. The complexity of the reverse algorithm depends on the coding mode of the two-dimensional code and the complexity of data conversion. When the reverse algorithm is designed, the integrity and the accuracy of the data are required to be considered, so that the restored data can truly reflect the information in the original data report.
In step S103, when submitting the filling data, judging whether the network is smooth, if the network connection fails, storing the filling data locally, so as to ensure that any filling content is not lost; and if the network connection is successful, submitting the filled data. The data filled by the user is stored in a local cache to ensure that the data can be saved even without a network. Once the network is reconnected, the system automatically detects and provides a one-touch commit portal. After the user clicks the submit button, all locally cached data is automatically uploaded to the server.
Further, in this embodiment, when uploading the local cache data to the server, the method includes the following steps:
acquiring a data identifier of local cache data, and determining a data attribute parameter corresponding to the local cache data from a database according to the data identifier;
determining a storage parameter according to the data attribute parameter, the data generation time length and the data caching time length of the local cache data;
and determining the uploading priority according to the storage parameters so as to upload the local cache data to the server based on the uploading priority.
Specifically, each local cache data in this embodiment has a corresponding data identifier, that is, a data name, and according to a corresponding relationship between the data identifier and the database, a data attribute parameter corresponding to the data identifier is determined, where the data attribute parameter in this embodiment is used to represent an attribute of data, that is, application performance, production performance, and so on. After the data attribute parameters are acquired, according to the data attribute parametersData generation duration->Data cache durationDetermining the storage parameter as +.>：
Wherein,、/>the generation factor and the cache factor are respectively represented, and the storage parameter is obtained by calculation based on the data attribute parameter, the data generation time length and the data cache time length, and is used for measuring the uploading priority of the data through the storage parameter, wherein the higher the storage parameter is, the higher the representing priority is, and the data needs to be uploaded to a server in time so as to ensure the efficiency of data application.
In addition, in some embodiments, verification information may be set for the two-dimensional code scanning tool, and when the two-dimensional code scanning tool is used to scan the two-dimensional code picture, the two-dimensional code picture is parsed when the verification information has the parsing right. Strict identity verification is added, and because the method is only aimed at the handover of the underground data report in the coal mine industry, the identity and equipment double verification is added after each equipment scans the two-dimension code. And data filling and modification can be only performed by specific equipment and specific account numbers, so that the safety of data transmission is improved.
