Referring to fig. 2 again, the charging service system 100 may be externally connected to the charging pile management system 200, specifically, the charging service system 100 may be communicatively connected to the charging pile management system 200 through a pre-agreed interconnection protocol, and may be implemented by calling an interface when data interaction is performed. The charging stake management system 200 may be responsible for the management of a plurality of charging stakes in one or more charging stations. The charging service system 100 controls the charging gun of the charging post in the charging station to charge the device to be charged through the charging post management system 200.
More specifically, in some embodiments of the present disclosure, the above-mentioned charging pile management system 200 includes a charging pile service end 210 and at least one charging pile operating system 220 that are in communication connection, where each charging pile operating system 220 is connected to a plurality of charging piles, and the charging pile service end 210 implements management of the charging piles through the charging pile operating system 220; to the outside, the charging pile server 210 is in communication connection with the charging server 110 of the charging service system 100, so as to implement communication between the charging service system 100 and the charging pile management system 200.

It should be noted that, the identification method of the plurality of two-dimensional codes of the present application may be applied to the charging service system shown in fig. 2, but the method is not limited to fig. 2, and fig. 2 is merely an exemplary illustration of one scenario of the present application, and does not limit the present application in any way.
For convenience of explanation, the front-end application is used as a fast electricity for explanation, and a plurality of two-dimensional codes are usually posted at a proper position of a charging gun, and whether the two-dimensional codes are two-dimensional codes of that channel, the two-dimensional codes at least represent identity information of a charging gun or positioning information of the identity of the charging gun. At least one two-dimensional code which is different from other two-dimensional codes in the two-dimensional codes is contained in the two-dimensional codes. If the two-dimensional codes comprise an already-received two-dimensional code, namely a two-dimensional code provided by a quick-electricity operator, the two-dimensional code provided by the operator of the front-end application is recorded as the already-received two-dimensional code, and other two-dimensional codes such as WeChat two-dimensional codes, payment treasured two-dimensional codes and the like are recorded as third-party two-dimensional codes, and the third-party two-dimensional codes are two-dimensional codes different from other two-dimensional codes; in another case, all of the two-dimensional codes are third party two-dimensional codes.
In some embodiments of the present application, the obtaining a plurality of two-dimensional codes to be identified includes: and obtaining a reading view field through the camera device, wherein the two-dimensional codes are positioned on the reading view field. That is, when the user scans the two-dimensional code of the charging gun by using the front-end application 120, the user can scan a plurality of two-dimensional codes at one time, so that the two-dimensional codes are located in the same lens (reading field of view) of the mobile phone camera.
In other embodiments of the present application, the obtaining a plurality of two-dimensional codes to be identified includes: and obtaining a plurality of reading view fields through the camera device, wherein the two-dimensional codes are distributed in the plurality of reading view fields.
The user can also move the user terminal equipment, so that the camera is moved to realize the scanning of a plurality of two-dimensional codes, and the two-dimensional codes are positioned under a plurality of lenses of the mobile phone camera. For example, a user scans a plurality of two-dimensional codes by using a fast battery, but under the same reading market, the plurality of two-dimensional codes are difficult to cover at one time, or the plurality of two-dimensional codes are scattered relatively, and in this case, the plurality of two-dimensional codes can be scanned by moving a camera. The two-dimensional code is usually in the form of an image, and in order to further improve the analysis accuracy, the two-dimensional code can be subjected to preprocessing such as image enhancement, noise reduction and the like before analysis and recognition.
Step S120: when the plurality of two-dimensional codes contain identifiable two-dimensional codes, obtaining target resource information through the identifiable two-dimensional codes.
When the front-end application scans a plurality of two-dimensional codes, firstly determining whether one or a plurality of identifiable two-dimensional codes exist in the two-dimensional codes.
Two conditions exist for the identifiable two-dimensional code, one is that the front end applies the own two-dimensional code, and the two-dimensional code is marked as the square two-dimensional code, and the other is that the three-dimensional code is associated with the target resource information or the identifiable two-dimensional code after the historical time, and the two-dimensional codes are converted into the identifiable two-dimensional code, so that the subsequent identification can be performed.
In some embodiments of the present application, determining whether at least one identifiable two-dimensional code exists in the plurality of two-dimensional codes includes: determining whether a square two-dimensional code exists in the plurality of two-dimensional codes, if so, determining that at least one identifiable two-dimensional code exists in the plurality of two-dimensional codes, and taking the square two-dimensional code as the identifiable two-dimensional code; if the two-dimensional codes do not exist, determining whether a third party two-dimensional code with an association relationship with the two-dimensional code or the resource information exists in the two-dimensional codes, if so, determining that at least one identifiable two-dimensional code exists in the two-dimensional codes, and taking the third party two-dimensional code with the association relationship with the two-dimensional code or the resource information as the identifiable two-dimensional code; if the third party two-dimensional code which has an association relation with the original two-dimensional code or the resource information does not exist in the plurality of two-dimensional codes, determining that at least one identifiable two-dimensional code does not exist in the plurality of two-dimensional codes.
In some embodiments of the present application, a service information base is provided to maintain and manage two-dimensional code information, where the service information base may be understood as a database of two-dimensional codes and resource information maintained by a front-end application operator, and in the service information base, at least a corresponding relationship between a front-end application's front-end two-dimensional code and the resource information is maintained, and before a plurality of two-dimensional codes are identified this time, related information of a third party two-dimensional code that has fallen into the base, that is, a "third party two-dimensional code that has fallen into the base" refers to that an association relationship has been formed between one third party two-dimensional code and resource information or between one identifiable two-dimensional code, and is maintained in the service information base.
In some embodiments of the present application, the unique two-dimensional code may be embodied in the form of, but not limited to, a unique resource locator (URL address), in which may be included, but not limited to: charging service provider information, charging gun identity information, configuration information and the like; the charging service provider information is quick service operator information, and the charging gun identity information can be directly a plaintext charging gun identity card identification number, a charging gun account number, a charging gun unique code and a charging gun exclusive number; or the character string of the dark text, the character string is used as positioning information, and the identity information of the charging gun can be found in a service information base.
In some embodiments of the present application, after the third party two-dimensional code is restored, the third party two-dimensional code is basically in the form of a character string, and sub-strings at different positions in the character string usually have different meanings and represent different information. All the front-end applications cannot recognize a third-party two-dimensional code, and cannot parse out the character string symbols or substrings in the character string symbols, but do not know the meaning represented by the character string symbols. For example, for a starting code of a charging gun, the character string must have at least part of identity information representing the charging gun, but for a third-party two-dimensional code, the front-end application cannot know the information represented by the character string before the association relationship between the third-party two-dimensional code and the resource information or the identifiable two-dimensional code is not established.
As shown before, after a plurality of two-dimensional codes are scanned quickly, whether the two-dimensional codes exist in the two-dimensional codes or not is first determined, if so, at least one identifiable two-dimensional code exists in the two-dimensional codes, the two-dimensional codes serve as the identifiable two-dimensional codes, and then the two-dimensional codes are analyzed and identified to obtain target resource information.
In the method, after the step of acquiring the plurality of two-dimensional codes to be identified, the step of directly judging whether the identifiable two-dimensional codes exist in the plurality of two-dimensional codes without displaying user selection prompt information.
In the prior art, if one front-end application APP scans a plurality of two-dimensional codes, a plurality of green marks are usually displayed on an interface of the front-end application of a user, so as to prompt the user to select the two-dimensional code to be identified. In the application, even if a plurality of two-dimensional codes are scanned, whether the identifiable two-dimensional codes exist in the plurality of two-dimensional codes can be automatically judged without selection of a user. In some embodiments, in order to enable the two-dimensional code which is originally unrecognizable to be subsequently recognized, a mapping relationship between the unrecognizable two-dimensional code in the plurality of two-dimensional codes and the target resource information may be established and maintained in a service information base, so as to complete a "database-falling operation".
The term "falling a database" can be understood as that an originally unrecognizable third party two-dimensional code has established an association relationship with a resource information or an identifiable two-dimensional code, and the association relationship can be maintained in a service information database, which can be deployed in a front-end application APP or maintained in a charging server, which is not limited in the application.
Specifically, in some embodiments, the operation of dropping the library may be performed by establishing an association between a third party two-dimensional code and the resource information, where the method further includes: performing image enhancement and denoising processing on the unidentifiable two-dimensional code; restoring the processed unidentifiable two-dimensional code into an original character string; determining a resource positioning character string in the original character string; and establishing a mapping relation between the resource positioning character string and the target resource information.
In an actual scene, the two-dimensional code is usually presented in the form of ulr address, and the two-dimensional code can be restored to the original character string according to a certain analysis rule, but some unidentifiable two-dimensional codes are not restored to ulr addresses because the meaning represented by the character string is not known. Therefore, when the originally unrecognizable third-party two-dimensional code is associated with and bound to the target resource information, all the substrings or the character string symbols at a certain position of the third-party two-dimensional code word string symbol can be bound to the target resource information, and a mapping relation can be established. For example, a substring of a third-party two-dimensional code is 987, the target resource information is 5632485, and a mapping relationship between the substring and the target resource information, i.e., 987= 5632485, can be established, where "=" represents a mapping relationship.
In other embodiments, the database may be further configured to store, by establishing an association relationship between two-dimensional codes, where when the plurality of two-dimensional codes includes identifiable two-dimensional codes, the obtaining target resource information through the identifiable two-dimensional codes includes: and establishing an association relationship among the two-dimensional codes based on the correspondence between the identifiable two-dimensional codes and the target resource information.
That is, after the target resource information is determined by the identifiable two-dimensional codes, an association relationship can be established between the two-dimensional codes, so that the two-dimensional codes point to the target resource information. Specifically, for the establishment of a specific association relationship, the establishment can be performed according to the image pixel information of different two-dimensional codes, the pixel information of each two-dimensional code is different, and the binding can be directly performed according to the pixels; the resource positioning character strings of different two-dimensional codes can be obtained through analysis, the resource positioning character strings of the two-dimensional codes are bound and stored, wherein one two-dimensional code points to the target resource information, and then the different two-dimensional codes with association relations point to the target resource information.
If the quick-electricity two-dimension codes do not exist in the two-dimension codes, determining that all the two-dimension codes are third-party two-dimension codes, but not all the third-party two-dimension codes cannot be identified, and the third-party two-dimension codes which are already stored in the business information base in the history time can be identified, so that whether the third-party two-dimension codes with association relation with the resource information or the identifiable two-dimension codes exist in the two-dimension codes can be determined, and if yes, determining that the identifiable two-dimension codes exist in the two-dimension codes. If a plurality of two-dimensional codes exist for the same charging gun, different two-dimensional codes point to the charging gun, therefore, if the number of the third party two-dimensional codes with association relation with the resource information or the identifiable two-dimensional codes is a plurality of, any one of the plurality of third party two-dimensional codes which are already in the warehouse can be taken as the identifiable two-dimensional code, and the target resource information is obtained through analysis and identification.
Therefore, the identifiable two-dimensional code comprises the square two-dimensional code and the third party two-dimensional code which is already in the warehouse. When the identifiable two-dimensional code is the square two-dimensional code, namely the quick-electricity two-dimensional code, the two-dimensional code is analyzed and identified according to the original logic. In some embodiments, if the quick-response two-dimensional code includes the charging robbery identity information of the plaintext, the parsed plaintext is directly used as the target resource information. In other embodiments, if the quick-electricity two-dimensional code includes target resource positioning information, for example, a sub-string that is a position of an original character string of the two-dimensional code, matching is performed in a service information base, for example, a quick-electricity charging gun information base, according to the sub-string, and if the sub-string can be matched with a corresponding charging gun, the identification information of the matched charging gun is used as the target resource information.
When the identifiable two-dimensional code is a third-party two-dimensional code, the identifiable two-dimensional code is a two-dimensional code which is already in a database in the service information base and has a strong binding relation with the target resource information or the identifiable two-dimensional code, so that the target resource information or the resource information of the target resource which is obtained by the identifiable two-dimensional code and has a mapping relation with the third-party two-dimensional code can be searched in the service information base.
Because the related information of the third party two-dimension codes which are already in the database is always maintained in the business information database, even if the third party two-dimension codes of other channels are scanned by adopting a front-end application, the third party two-dimension codes can be identified. In some embodiments, the corresponding relationship between the third-party two-dimensional code and the target resource information may be determined based on the association relationship between the plurality of two-dimensional codes, so as to obtain corresponding target resource information, for example, the resource locator of the third-party two-dimensional code is used for searching in the service information base to obtain corresponding resource information as the target resource information.
For example, when the user scans a third party two-dimensional code that has fallen into the library by using the fast-forwarding APP, the target resource information may be determined by the following method, and in some embodiments, the method further includes: acquiring a third party two-dimensional code to be identified; restoring the third-party two-dimensional code into an original character string; dividing the original character string to obtain at least one character sub-string; and determining resource information with a mapping relation with the third-party two-dimensional code as target resource information according to each character substring.
For the third party two-dimension code which has fallen into the database, even if the user scans by using the quick electricity, the quick identification can be performed according to the information maintained in the service information database, the quick identification is firstly restored into an original character string symbol, then the original character string is divided into a plurality of sub-strings, if the symbol "," ""/", and the like are encountered, the sub-strings are divided into one sub-string, and further, each sub-string can be matched in the service information database, so that the target resource information is obtained.
Step S130: and when the plurality of two-dimensional codes do not contain the identifiable two-dimensional codes, obtaining target resource information through the association relation between the unidentifiable two-dimensional codes and the identifiable two-dimensional codes.
If it is determined that the two-dimensional codes are unidentifiable two-dimensional codes, that is, the two-dimensional codes do not exist, that is, the two-dimensional code of the party is not present, and that the two-dimensional code of the third party already exists in the service information base, then step S130 is entered.
For the situation that identifiable two-dimensional codes do not exist in the plurality of two-dimensional codes, the association relation between the two-dimensional codes and the identifiable two-dimensional codes pointing to the same target resource information can be established, then the target resource information is obtained through the association relation, the identifiable two-dimensional codes under the situation can be one two-dimensional code maintained in the background and pointing to the same target resource with the plurality of two-dimensional codes, and the identifiable two-dimensional codes can be marked as source two-dimensional codes or operation two-dimensional codes, and the source two-dimensional codes are identifiable by front-end application.
Still taking the foregoing charging service scenario as an example, the source two-dimensional code characterizes identity information of a corresponding resource, such as identity information of a charging gun, where the identity information of the charging gun may be, but is not limited to, a plaintext charging gun identity card identifier, a charging gun account number, a charging gun unique code, a charging gun dedicated number, and so on. The source two-dimension code can be generated according to a certain rule, such as a snowflake algorithm, and is stored in a business information base in the form of an image. When the source two-dimensional code is configured, firstly, generating a two-dimensional code containing or pointing to the resource information of the target resource according to the resource information of the resource as the source two-dimensional code, then obtaining the related information of the first unidentifiable third-party two-dimensional code through scanning, and finally binding and storing the related information of the unidentifiable third-party two-dimensional code with the source two-dimensional code.
The method is particularly used for scenes without the two-dimension codes of the parties, and due to some policy problems or other problems, the two-dimension codes are not allowed to be newly added, for the scenes with the two-dimension codes of the third party, which cannot be identified originally, the front end application of the two-dimension codes of the third party, the staff can establish an association relationship with the source codes pointing to the same resource in advance, and when the two-dimension codes of the third party are scanned, the association relationship between the two-dimension codes which cannot be identified and the target resource information is determined based on the association relationship of the two-dimension codes of the third party, so that the corresponding target resource information is obtained. If the association relation can be used, the corresponding source two-dimensional code is jumped, and the target resource information is obtained by analyzing the source code. After step S130 is entered, a plurality of two-dimensional codes, which are usually third-party two-dimensional codes, may be traversed, and for each traversed third-party two-dimensional code, it is determined whether there is a source two-dimensional code that has an association relationship with the third-party two-dimensional code established in a history time, and specifically, the source two-dimensional code may be searched in a service information base to find whether there is a corresponding source two-dimensional code for the third-party two-dimensional code. If the source two-dimensional code exists, analyzing and identifying the source two-dimensional code to obtain target resource information.
The application also provides a spam scheme, and in particular, in some embodiments of the application, the method further comprises the following steps: if the target resource information cannot be obtained through the association relation between the unidentifiable two-dimensional code and the identifiable two-dimensional code, traversing the two-dimensional codes; analyzing the traversed two-dimensional code according to at least one preset analysis rule to obtain corresponding candidate resource information; and determining the validity of the candidate resource information, if the candidate resource information is legal, taking the candidate resource information as the target resource information, and ending the traversal.
According to the application, at least one analysis rule is preset in advance, and the analysis is not only to restore the two-dimensional code into the original character string, but also to analyze the meaning represented by the original character string, such as the identity information of the charging gun, for example, the No. 1a charging gun of the No. 01 charging pile of the B charging station of the A city.
Specific analysis rules are various, taking target resource information as a charging gun ID (identity) as an example, for example, a format of character strings restored according to two-dimensional codes, and taking a substring at a certain position in the character strings as the charging gun ID; secondly, according to the format of the two-dimensional code character string, converting the format of a substring at a certain position to be used as a charging gun ID; the third party uses the entire character string as the charging gun ID, etc., and the present application is not limited thereto.
The above-mentioned preset analysis rules are adopted to analyze the two-dimensional codes one by one according to a certain sequence, when one two-dimensional code is traversed, if one resource information is obtained through analysis, the resource information is marked as candidate resource information, and it is to be noted that the analysis rules are preconfigured and configured according to some common rules in the industry, and the candidate resource information possibly analyzed by the rules may or may not be paired. Therefore, the validity of the charging gun needs to be checked, if the identity information of the charging gun is 8-bit Arabic numerals plus one-bit check symbols, candidate resource information can be checked according to the rule; in order to ensure the correctness and legality of the resource, the candidate resource information is matched in a service information base, namely whether the candidate resource information is contained in the service information base or not is determined, if so, the candidate resource information is used as target resource information, and the traversal is finished; if the candidate resource information is not contained, determining that the candidate resource information is illegal, and discarding the candidate resource information.
It should be noted that the preset parsing rules may be multiple, when traversing to a two-dimensional code, multiple parsing rules are adopted to parse the two-dimensional code for multiple times, if each parsing rule does not obtain candidate resource information, the two-dimensional code is abandoned, and the next two-dimensional code is traversed; if any analysis rule is adopted to analyze the candidate resource information, entering a verification step of legality; it should be noted that, in general, a situation that one two-dimensional code adopts various algorithms to analyze candidate resource information and each candidate resource information is legal does not occur, so that a plurality of analysis methods are adopted, and at most one legal candidate resource information is obtained.
In some embodiments of the application, the method further comprises: if all the two-dimensional codes cannot be analyzed or candidate resource information of all the two-dimensional codes is illegal, an information prompt which cannot be identified is returned.
If the two-dimensional codes which are scanned quickly cannot be analyzed, or the candidate resource information obtained through analysis is illegal, determining that the two-dimensional codes cannot be scanned, and returning an information prompt which cannot be identified. Even if the two-dimensional codes of various channels can not be completely covered by adopting the modes, the two-dimensional codes can not be identified, and the information prompt of failure to identify is returned.
As can be seen from fig. 1, the present application provides a method for identifying multiple two-dimensional codes, when a front end application scans multiple two-dimensional codes to be identified, it is determined whether there are identifiable two-dimensional codes in the two-dimensional codes, if yes, target resource information is directly determined according to the identifiable two-dimensional codes; if the identifiable two-dimensional code does not exist, the association relationship between the unidentifiable two-dimensional code and the identifiable two-dimensional code in the plurality of two-dimensional codes can be established, so that the target resource information can be determined through the association relationship.
