As shown in fig. 1, the industrial internet identification system includes a national top level node, a secondary level node, and an enterprise node. The data identification system of the embodiment comprises a vehicle-mounted terminal which can be connected with the enterprise node in a communication mode.

The industrial internet identification code is referred to as identification for short hereinafter, and can be inquired in an industrial internet identification system. As shown in fig. 1, a plurality of enterprise nodes exist in the industrial internet identification system, and the vehicle-mounted terminal directly interacts with the enterprise node through the data identification issued by the enterprise node, without passing through other nodes in the industrial internet identification system. The vehicle-mounted terminal is an electronic device for requesting the release of the identifier, and can be operated by a user. When a user needs to publish data to an industrial Internet identification system, an identification publishing request is sent to the enterprise node to which the user belongs through the vehicle-mounted terminal.

Fig. 2 is a flowchart of an industrial internet identifier issuing method according to an embodiment of the present invention.

As shown in fig. 2, the method specifically includes the following steps:

s110, the vehicle-mounted terminal obtains vehicle data and a verification identifier corresponding to the vehicle data, wherein the data content corresponding to the verification identifier is related to the vehicle data.

Vehicle data refers to information related to vehicle operating conditions, including: vehicle speed, mileage, fuel consumption, battery energy monitoring, camera image information, and the like.

Optionally, the in-vehicle device includes: TBOX, CAN bus, vehicle-mounted camera, etc.; the vehicle data is acquired by the vehicle-mounted terminal through TBOX or analysis vehicle-side CAN bus signals, or acquired by connecting vehicle-mounted equipment such as a vehicle-mounted camera through WIFI, Bluetooth and the like.

And then, the vehicle-mounted terminal acquires a check identifier corresponding to the vehicle data to be issued. The verification identification is also an identification issued in an industrial Internet identification system, and the corresponding data content is related to the vehicle data and can be used for verifying the accuracy of the vehicle data.

In a specific embodiment, if the vehicle data is the number of charging times acquired by the vehicle-mounted device through the in-vehicle device, and the data related to the vehicle data includes the number of charging times recorded by the charging pile device, an identifier corresponding to the number of charging times recorded by the charging pile device is used as a verification identifier of the vehicle data.

And S120, the vehicle-mounted terminal calls the data corresponding to the check identifier through an industrial Internet identifier system, and checks the vehicle data according to the data corresponding to the check identifier.

And the data corresponding to the check identifier is stored in an industrial Internet identifier system or another vehicle-mounted terminal for identifier release, and needs to be called through the industrial Internet identifier system. The data called is used to verify the accuracy of the vehicle data.

Optionally, verifying the vehicle data according to the data corresponding to the verification identifier includes: and if the vehicle data obtained according to the data corresponding to the verification identification is not inconsistent with the vehicle data obtained through the in-vehicle equipment, the verification is successful.

In the above embodiment, if the sum of the charging times of a vehicle in a period of time recorded by a plurality of charging piles is greater than the charging times of the vehicle in the same period of time recorded by the vehicle, it indicates that the charging times of the two sources are contradictory, and the verification fails; if the sum of the charging times of a vehicle in a period of time recorded by the charging piles is less than or equal to the charging times of the vehicle in the same period of time recorded by the vehicle, the charging times of the two sources have no contradiction, and the method accords with the principle and is successful in verification.

And S130, after the verification is successful, the vehicle-mounted terminal issues the vehicle data to the industrial internet identification system as a new identification.

The vehicle-mounted terminal of the embodiment accesses the physical and chemical vehicle into the digitalized industrial internet identification system by adding the hardware equipment on the basis of not changing the original design of the vehicle, so that the identification system can acquire various data of the vehicle in real time.

The technical effects of the embodiment are as follows: this embodiment is through mobile unit with vehicle data issuing for industry internet sign, and the sign issuing main part is more nimble, has improved the convenience of vehicle data sharing. Before the identification is issued, the vehicle data is verified through the data corresponding to the verification identification, so that the diffusion of wrong vehicle data in an internet identification system is reduced, and the data reliability of the internet identification system is improved. Because the data corresponding to the check mark may come from other industries, enterprises or vehicles, the embodiment can realize inter-enterprise and inter-industry industrial information data intercommunication, and improve the information fusion capability of the whole industrial internet.

On the basis of the above-described embodiment and the following embodiments, the present embodiment refines the acquisition process of the check mark. Optionally, the check identifier may be preset by a user of the vehicle-mounted terminal, and the preset check identifier may be third-party data concerned by the user. The user preset mode can directly and accurately meet the requirements of the user, and the pertinence is stronger.

In addition, the check identifier can also be automatically determined by the vehicle-mounted terminal. Optionally, the obtaining of the vehicle data and the verification identifier corresponding to the vehicle data specifically includes the following steps:

step one, according to the content of the acquired vehicle data, a verifier capable of providing related data content is determined.

The vehicle data in the invention comprises data content and data value, and are stored in the terminal equipment after being acquired. In the embodiment, a verifier is determined according to the content of the vehicle data, wherein the verifier refers to other enterprise nodes or devices accessing to the industrial network identification system and can provide data content related to the vehicle data. Optionally, the verifier includes: the system comprises a charging pile management party, a vehicle storage and maintenance party or a driving road condition monitoring party.

In a specific embodiment, if the content of the vehicle data is power battery parameter information, determining that a calibrator capable of providing related data content is a charging pile manager. Optionally, the power battery parameter information is acquired by an in-vehicle battery management system; the charging pile management party comprises a charging pile management enterprise or a charging pile device and can provide charging information related to the power battery parameter information.

And if the content of the vehicle data is the parameter information of the whole vehicle parts, determining that the verifier capable of providing the related data content is a vehicle storage and maintenance party. Optionally, the parameter information of the parts of the whole vehicle is acquired through a CAN bus; the vehicle storage and maintenance method includes: vehicle storage maintenance enterprise can provide the maintenance information of whole car and spare part.

And if the content of the vehicle data is the driving road condition information, determining that the calibrator capable of providing the related data content is the driving road condition monitoring calibrator. Optionally, the driving road condition information is acquired through a vehicle-mounted camera; the driving road condition monitoring side comprises: the traffic management department or the roadside equipment can provide violation information of the vehicle or road condition information shot by the roadside camera.

And step two, selecting a verification identifier corresponding to the vehicle data from at least one identifier issued by the verifier in an industrial internet identifier system according to the description information of the identifier.

And each identifier corresponds to description information used for describing the data content corresponding to the identifier, and the identifier publisher publishes the data content together with the identifier in the industrial Internet system. After the verifying party determines, the selection range of the verification identification is reduced from the identification issued in the whole industrial internet system to the identification issued by the verifying party, and only the verification identification needs to be selected from at least one identification issued by the verifying party.

Specifically, the vehicle-mounted terminal firstly inquires description information of all identifications issued by a verifier through the industrial internet, and then determines verification identifications capable of providing related data contents according to the description information and the contents of the vehicle data. Optionally, a keyword in the description information of a tag is extracted through a text analysis method, and if the keyword matches with the content of the vehicle data, the tag is determined as a verification tag. It should be noted that the query object here is description information of the identifier, and data corresponding to the identifier does not need to be called, and a large amount of network resources do not need to be occupied.

According to the embodiment, firstly, a checking party capable of providing related data content is determined according to the content of the vehicle data, so that the selection range of the checking identifier is reduced; and then, selecting a verification identifier from at least one identifier issued by a verifier according to the matching of the description information of the identifier and the data content. The efficiency of determining the identification is improved in a step-by-step screening mode; meanwhile, automatic determination of the check mark is realized, and manual setting aiming at different vehicle data is not required.

On the basis of the above-described embodiment and the following-described embodiment, the present embodiment adds authentication of the terminal identity before the identifier is issued. Optionally, terminal identity information and a private key are written in hardware of the vehicle-mounted terminal; before issuing the vehicle data to the industrial internet identification system as a new identification, the method further comprises the following steps: and issuing the terminal identity information and a public key corresponding to the private key to the industrial internet identification system, wherein the industrial internet identification system is used for carrying out vehicle-mounted terminal identity authentication by using the public key.

When the vehicle-mounted terminal is designed, identity information and a private key are distributed to each vehicle-mounted terminal and are implanted into the terminal in a hardware mode. The identity information (such as identity ID) is used for marking the identity of the vehicle-mounted terminal, and the identity can be issued through the industrial internet identification system only by the vehicle-mounted terminal which issues the identity information to the industrial internet identification system.

And the vehicle-mounted terminal stores an encryption algorithm corresponding to the private key and is used for generating a corresponding public key. After the terminal identity information and the private key are burnt in hardware of the vehicle-mounted terminal, the vehicle-mounted terminal generates a public key corresponding to the private key according to the encryption algorithm, and issues the identity information and the public key to an industrial internet identification system for the industrial internet identification system to perform identity authentication on the vehicle-mounted terminal. Optionally, the vehicle-mounted terminal issues the public key as a vehicle data to the industrial internet identification system as an identifier.

And after the vehicle-mounted terminal issues the terminal identity identification and the public key corresponding to the private key to the industrial internet identification system, issuing the vehicle data to the industrial internet identification system as a new identification. The method specifically comprises the following steps:

step one, the vehicle-mounted terminal sends terminal identity information and an identification issuing request to the industrial internet identification system, and the identification issuing request is obtained by adopting the private key for encryption.

When a vehicle-mounted terminal needs to issue an identifier to an industrial internet identifier system, firstly, an identifier issuing request is generated, wherein the request comprises identity information of the vehicle-mounted terminal; then, encrypting the identifier issuing request by adopting a private key of the vehicle-mounted terminal to obtain a final identifier issuing request; and finally, sending the terminal identity information and the final identifier release request to an industrial Internet identifier system.

And step two, the industrial internet identification system decrypts the identification issuing request by adopting the public key corresponding to the terminal identity information, and if the other terminal identity information obtained after decryption is consistent with the terminal identity information, the identity authentication of the vehicle-mounted terminal is passed.

After receiving an identity information and an identifier issuing request sent by a terminal, the industrial internet identifier system adopts a public key stored locally to authenticate the identity of the terminal in order to prevent the identity information from being a forged identity or prevent the received identity information and/or the identifier issuing request from being falsified. Specifically, the industrial internet identification system firstly searches a public key corresponding to the identity information locally; then, the public key is adopted to decrypt the received identifier issuing request to obtain the other identity information included in the identifier issuing request; and if the other identity information is consistent with the one identity information, the one identity information is considered as the real identity of the terminal, and the identity authentication is passed.

And step three, after the identity authentication is passed, the vehicle-mounted terminal issues the vehicle data to the industrial internet identification system as a new identification.

In the embodiment, the terminal identity information is authenticated by adopting a mode of matching the terminal identity information, the public key and the private key, wherein the terminal identity information and the private key are implanted into the terminal in a hardware mode, and compared with the terminal in which the terminal is stored in a software mode, the terminal identity information and the private key can be effectively prevented from being tampered and stolen, and the security is higher. The public key is not preset in the industrial internet identification system, but is generated by the vehicle-mounted terminal and issued to the industrial internet identification system for identity verification or data encryption and decryption of the industrial internet identification system, so that the flexibility of public key generation and use is improved.

On the basis of the above-described embodiment and the following-described embodiment, the present embodiment refines the process of new identifier issuance. As shown in fig. 1, a plurality of enterprise nodes exist in the industrial internet identification system, and for convenience of distinguishing and presentation, for a specific vehicle-mounted terminal, an identification is issued through the enterprise node to which the terminal belongs, and the enterprise node interacts with other nodes in the industrial internet identification system.

Optionally, the vehicle-mounted terminal issues the vehicle data to the industrial internet identification system as a new identification, and specifically includes the following steps:

s131, the vehicle-mounted terminal acquires the data type of the vehicle data.

The present embodiment divides the vehicle data into two data types according to the modification frequency and the security level of the vehicle data: dynamic data and static data. The dynamic data refers to data which needs to be frequently updated and/or has a higher security level after being created, such as camera data. Static data refers to data that is less frequently modified and/or less secure after creation. The data type of the vehicle data may be customized by a user, or may be defined by a historical usage condition of the vehicle data, which is not limited in this embodiment.

In one specific embodiment, after responding to the first identifier issuing request, the vehicle-mounted terminal firstly acquires the data type of the vehicle data. The first identifier issuing request refers to a request received by the vehicle-mounted terminal for issuing the data identifier to the industrial internet identifier system, and the request can be from a user operating the vehicle-mounted terminal or from a sensor connected with the vehicle-mounted terminal, such as a camera.

S132, if the data type is dynamic data, the vehicle-mounted terminal creates a dynamic identification and a dynamic identification data body of the vehicle data and issues the dynamic identification to the enterprise node to which the vehicle-mounted terminal belongs.

And after the data type is acquired by the vehicle-mounted terminal, different identifier issuing strategies are selected according to the data type. In the following, different identifier issuing policies are explained in different cases by specific embodiments.

The data type is dynamic data

The dynamic data needs to be frequently updated and/or has a high safety level, is suitable for being stored locally in the vehicle-mounted terminal and is subjected to real-time data refreshing operation locally, so that the vehicle-mounted terminal locally creates the identification and the identification data body of the vehicle data. The data storage in the industrial internet identification system has a specific format and standard, and the identification data body refers to a data body constructed according to the specific format and standard. The vehicle data is mostly stored locally according to a data standard customized by the vehicle-mounted terminal, and is usually different from the data standard finally issued to an industrial internet identification system. Therefore, an identification data body needs to be created for the vehicle data in the identification publishing process, so that the data content can be identified and inquired through the industrial internet.

In order to distinguish from the identifier and identifier data body created at the enterprise node, the identifier and identifier data body created locally by the vehicle-mounted terminal is referred to as "dynamic identifier" and "dynamic identifier data body" in the present embodiment. After the dynamic identification and the dynamic identification data body are created, the vehicle-mounted terminal issues the dynamic identification to the affiliated enterprise node, and the dynamic identification is issued to the industrial internet identification system through the affiliated enterprise node. Optionally, the vehicle-mounted terminal does not issue the dynamic identification data body to the enterprise node, and the dynamic identification data body is stored locally in the vehicle-mounted terminal.

(II) the data type is static data

And when the data type is static data, the data identification system further comprises an enterprise node to which the vehicle-mounted terminal belongs. Because the static data is rarely updated and can be uploaded to the enterprise node for long-time storage, if the data type is static data, the vehicle-mounted terminal sends a second identifier issuing request and the vehicle data to the enterprise node to which the vehicle-mounted terminal belongs. And the affiliated enterprise node responds to the second identification issuing request, locally creates an identification and an identification data body of the vehicle data, and issues the identification to an industrial Internet identification system.

For the sake of distinction and description, the identification and identification data volumes created locally by the enterprise node to which it belongs are referred to as "static identification" and "static identification data volume". And the static identification data body is stored in the enterprise node.

Compared with a mode of completely uploading data to the enterprise nodes, the vehicle-mounted terminal provided by the embodiment can selectively upload the identification data body, and the interaction mode between the vehicle-mounted terminal and the enterprise nodes is more flexible. For data which does not need to be stored for a long time, the data are directly stored in the local vehicle-mounted terminal, and the data can be immediately deleted once the data are overdue, so that the data do not have any influence on the enterprise nodes. Meanwhile, the vehicle-mounted terminal uploads the identification and description to the enterprise node to which the vehicle-mounted terminal belongs, and does not upload an identification data body, so that high privacy protection of data is realized, and the risk that the data is accidentally tampered at the enterprise node to which the vehicle-mounted terminal belongs is avoided.

The technical effects of the embodiment are as follows: the embodiment breaks the mode that the vehicle data need to be uploaded to the affiliated enterprise node to create and release the identification, and for the dynamic data with frequent modification, the vehicle-mounted terminal directly creates and stores the dynamic identification data body locally and only sends the dynamic identification to the affiliated enterprise node. On one hand, when the data is released and modified, a large amount of vehicle data does not need to be sent to the enterprise node, so that the consumption of a large amount of network bandwidth and the occupation of server resources of the enterprise node are avoided, and the batch release of the identification is convenient to realize; on the other hand, the data storage range is limited to be local to the vehicle-mounted terminal, so that the risk that the identification data body is tampered in the enterprise node to which the identification data body belongs can be avoided, and the safety of the data is guaranteed.

On the basis of the above-described embodiment and the following embodiments, the present embodiment refines the dynamic identification and the process of creating the dynamic identification data volume. Optionally, the vehicle-mounted terminal creates a dynamic identifier and a dynamic identifier data body of the vehicle data, and specifically includes the following steps:

step one, the vehicle-mounted terminal selects a corresponding identification data template according to the vehicle data field of the vehicle data, wherein the identification data template comprises at least one identification data field.

Optionally, the local vehicle data is connected by selecting a data connection plug-in, such as an Oracle database connection plug-in, an Excel operations plug-in, or the like. Each piece of vehicle data corresponds to an identification data template for creating a corresponding identification data volume.

Optionally, the identification data template is pre-customized by the vehicle-mounted terminal. Specifically, the vehicle data comprises a plurality of vehicle data fields, the identification data template comprises a plurality of identification data fields, and the identification data template corresponding to the vehicle data can be generated and stored by establishing a mapping relation between the plurality of vehicle data fields and the plurality of data representation fields. For convenience of description, the mapping relationship is referred to as an identification data mapping rule, and may also be pre-defined by the vehicle-mounted terminal, for example, by an operating user of the vehicle-mounted terminal.

Optionally, if one of the vehicle data has no dedicated identification data template, one of the existing identification data templates is selected for application. Optionally, the selecting, by the vehicle-mounted terminal, a corresponding identification data template according to the vehicle data field of the vehicle data includes: and if the data fields of one identification data template comprise all vehicle data fields of the vehicle data source and the number of redundant data fields of the identification data template is minimum, selecting the identification data template as the identification data template corresponding to the vehicle data source.

And secondly, the vehicle-mounted terminal creates a dynamic identification data body for the vehicle data according to an identification data mapping rule and the identification data template.

The identification data mapping rule is used for specifying a mapping relation between the vehicle data field and the identification data field. For example, the vehicle data field "name" is mapped to the identification data field "Date", etc. The identification data mapping rule may also be pre-defined by the vehicle-mounted terminal, for example, by an operating user of the vehicle-mounted terminal.

And step three, the vehicle-mounted terminal creates a dynamic identifier according to a dynamic identifier coding rule and the dynamic identifier data body.

The dynamic identification coding rule is a method for obtaining dynamic identification codes according to a dynamic identification data body. The dynamic identification coding rule can also be pre-customized by the vehicle-mounted terminal, for example, customized by an operation user of the vehicle-mounted terminal.

In the existing identification data volume creation mode, when a user wants to publish a large amount of local vehicle data as an identification, a manual addition mode is mostly adopted to create an identification data volume for the vehicle data, or import data is exported by means of a third-party ETL tool, or data is injected by means of Excel, and no convenient and special identification data volume conversion tool exists. When the data structure is complex, a development interface is generally required to be customized, and when errors occur in batch transmission of identification data, the errors cannot be corrected in time; and the operation mode is complex and lacks flexibility.

The data aggregation function provided by the embodiment can be quickly associated with various local databases of common types, including Mysql, Oracle, Sqlserver and the like, and various types of data sources are connected in a plug-in mode. Meanwhile, the definition authority of the identification data mapping rule and the dynamic identification coding rule is released to the vehicle-mounted terminal, the identification data template is edited by customizing the vehicle data field, the identification data field, the field mapping rule and the identification conversion rule, and the dynamic identification data body is automatically generated through the identification data template. The identification data template can be repeatedly used after being generated, and for a plurality of vehicle data with the same original field, the corresponding dynamic identification data body can be quickly generated by adopting the same identification data template without selecting by hand each time, so that mass vehicle data can be conveniently released as the identification in batch. In addition, error data in the conversion process can be timely presented to a user through an error processing mode of a mark release ton user-defined mode, and the operation is simple and convenient.

On the basis of the above-described embodiment and the following-described embodiment, the present embodiment explains a process of dynamic data update. Optionally, after the vehicle-mounted terminal creates the dynamic identifier and the dynamic identifier data body of the vehicle data, the method further includes the following steps:

s210, the vehicle-mounted terminal updates the vehicle data to be updated and acquires the identification type of the vehicle data to be updated.

In a specific embodiment, after the identifier is successfully issued, the vehicle-mounted terminal responds to the first data updating request, first updates the vehicle data to be updated, and acquires the identifier type of the vehicle data to be updated. The first data update request refers to a request for updating vehicle data received by the in-vehicle terminal, and the request may be from a user operating the in-vehicle terminal or from a sensor connected to the in-vehicle terminal, such as a camera.

And S220, if the identification type is a dynamic identification, the vehicle-mounted terminal updates a corresponding dynamic identification data body according to new vehicle data.

And after the identification type of the updated vehicle data is obtained by the vehicle-mounted terminal, different identification data body updating strategies are selected according to the identification type. The identification type corresponds to a data type and comprises a dynamic identification and a static identification. In the following, different update policies for identification data are described in different cases by specific embodiments.

(one) the identification type is dynamic identification

Since the dynamic identification data body is stored in the vehicle-mounted terminal, by using the dynamic identification data body creation method of the above embodiment, a new dynamic identification data body is created for the updated vehicle data, that is, the update of the dynamic identification data body is completed. All operations are completed locally, the method is fast and safe, and the outside only obtains the latest dynamic identification data body without sensing the updating process of the dynamic identification data body.

Optionally, a creation trigger is set in the vehicle-mounted terminal due to frequent dynamic data updating. The creation trigger may be a hardware chip or a software program within the vehicle terminal for specifying a trigger rule for creating a new dynamic identification data volume for the updated vehicle data. Such as real-time creation, delay time creation, or timed creation, etc. Optionally, the creation trigger monitors whether the vehicle data is updated, and when the update of the vehicle data meets the trigger rule, the vehicle-mounted terminal creates a new dynamic identification data body for the latest vehicle data.

(II) the type of the mark is static mark

When the identification type is static identification, the data identification system also comprises the enterprise node. Because the static identification data body is stored in the enterprise node, the enterprise node creates a new static identification data body for the updated vehicle data, namely the static identification data body is updated.

Specifically, if the identification type is a static identification, the vehicle-mounted terminal sends a second data updating request and the new vehicle data to the enterprise node; and the affiliated enterprise node responds to the second data updating request and updates the corresponding static identification data body according to the new vehicle data.

Optionally, a request trigger is set in the in-vehicle terminal. The request trigger may be a hardware chip or a software program in the vehicle-mounted terminal, and is used for specifying a trigger rule for sending the second data update request and the new vehicle data to the enterprise node. Such as a real-time request, a delay time request, or a timing request, etc. Optionally, the request trigger monitors whether the vehicle data is updated, and when the update of the vehicle data meets the trigger rule, the vehicle-mounted terminal sends a second data update request and the latest vehicle data to the enterprise node.

It should be noted that, regardless of the update of the dynamic identification data volume or the static identification data volume, only the identification data volume is updated, and the identification is not updated. The identification code is kept unchanged after being generated.

In the existing identification data body updating mode, if the identification data is updated frequently, a data updating request needs to be sent to the affiliated enterprise node continuously, and the affiliated enterprise node needs to verify the identity and the authority of the request terminal continuously, search for the identification data body and update. When the data volume is large and the data updating requests are more, a large amount of network bandwidth is consumed, server resources of the enterprise nodes are occupied, and network faults are likely to cause that the data cannot be updated in real time or the server resources are insufficient, so that normal services cannot be provided for the outside.

According to the method provided by the embodiment, the dynamic identification data body is stored locally, the vehicle-mounted terminal can modify the dynamic identification data body at any time, identity and authority verification is omitted, data searching efficiency is improved, an updating request and updated vehicle data are not sent, and network bandwidth and server resources are saved.

On the basis of the above-described embodiment and the following-described embodiment, the present embodiment describes a process of dynamically identifying a query. Optionally, after the vehicle-mounted terminal creates the dynamic identifier and the dynamic identifier data body of the vehicle data, the method further includes:

s310, the enterprise node to which the user belongs judges whether the to-be-inquired mark is the dynamic mark created by the vehicle-mounted terminal.

After the identification is successfully issued, the data demand end can access an industrial internet system, and the issued identification is inquired through the affiliated enterprise node to obtain a corresponding identification data body. In a specific embodiment, any data demand end uses a client end of an industrial internet identification system or a WEB end of a logging identification country node to input an identification code to be queried, or retrieves the identification code to be queried through description information, and sends an identification query request.

When a data demand end needs to inquire an identification data body corresponding to a certain identification, a first identification inquiry request is sent to an enterprise node corresponding to a creator of the identification through other nodes in an industrial internet identification system. Specifically, the analysis of the industrial internet identification system analyzes the identification code, and forwards the first identification query request to the enterprise node corresponding to the identification code.

And the affiliated enterprise node responds to the first identification query request, and firstly searches a corresponding identification data body locally according to the identification to be queried. And if the identification data body is locally stored, feeding the identification data body back to the data demand side. And if the identification data body is not stored locally, judging whether the to-be-inquired identification is a dynamic identification created by the subordinate vehicle-mounted terminal.

Optionally, a dedicated dynamic identifier receiving interface is set in the affiliated enterprise node, and an identifier received through the interface is defaulted to be a dynamic identifier issued by a subordinate enterprise node. The dynamic identification can be marked by recording the receiving interface of the identification or setting a flag bit for the dynamic identification, and whether the identification to be inquired is issued by the lower-level enterprise node or not is identified.

S320, if the to-be-inquired identification is the dynamic identification created by the vehicle-mounted terminal, the enterprise node requests the latest dynamic identification data body from the vehicle-mounted terminal, and then feeds back and deletes the latest dynamic identification data body.

In a specific embodiment, if the identifier to be queried is a dynamic identifier created by the vehicle-mounted terminal, the enterprise node sends a second identifier query request to the vehicle-mounted terminal; the vehicle-mounted terminal responds to the second identification query request and feeds back the latest dynamic identification data body to the enterprise node to which the vehicle-mounted terminal belongs; and feeding back and deleting the latest dynamic identification data body by the enterprise node to which the enterprise node belongs.

Optionally, after the enterprise node feeds the dynamic identification data body back to the data demand side, the dynamic identification data body is deleted immediately; or deleting the cache after preset time to prevent high concurrent access.

In the existing identification query mode, because the identification data bodies are all stored in nodes at all levels of an industrial internet system, the affiliated enterprise nodes cannot request the identification data bodies from the vehicle-mounted terminal. The method of the embodiment changes the data feedback mode of the enterprise node, and is an extension of the existing industrial internet system.

On the basis of the above embodiment and the following embodiment, the present embodiment describes a process for dynamically identifying a downline. Optionally, after the vehicle-mounted terminal creates the dynamic identifier and the dynamic identifier data body of the vehicle data, the method further includes:

and S410, the vehicle-mounted terminal acquires the identifier type of the identifier to be offline.

After the identifier is successfully issued, when a certain identifier or a certain identifier data body is not expected to be exposed to the outside, the identifier can be offline without deleting the identifier data body.

In a specific embodiment, after receiving the first data offline request, the vehicle-mounted terminal first obtains an identifier type of the identifier to be offline. The first data offline request may be from a user operating the in-vehicle terminal.

And S420, if the identification type is a dynamic identification, the vehicle-mounted terminal sets the corresponding dynamic identification data body as an inquireable data body.

And after the vehicle-mounted terminal acquires the identification type, selecting different identification offline strategies according to the identification type. In the following, different offline identification policies are described in different cases by specific embodiments.

(one) the identification type is dynamic identification

Because the dynamic identification data body is stored locally in the vehicle-mounted terminal, the enterprise node to which the dynamic identification data body belongs cannot acquire the dynamic identification data body from the dynamic identification client only by setting the dynamic identification data body to be not inquired, and the offline of the dynamic identification is realized. When the identification data body is required to be provided externally, the dynamic identification data body is only required to be set to be inquired.

(II) the identification type is static identification

When the identification type is static identification, the data identification system also comprises the enterprise node. And the vehicle-mounted terminal sends a second data offline request to the enterprise node. And the enterprise node responds to the second data offline request and sets the corresponding static identification data body as an un-queriable data body.

And the static identification data body is stored in the affiliated enterprise node, so that the vehicle-mounted terminal sends a second data offline request to the affiliated enterprise node. And the affiliated enterprise node responds to the second data offline request, sets the corresponding static identification data body as an inquirable data body, and the data demand end cannot acquire the static identification data body from the affiliated enterprise node, namely offline of the static identification is realized. When a user wants to provide an identification data body externally, the user only needs to request the enterprise node to set the static identification data body to be inquired.

It should be noted that, in the process of offline identification, only the query permission of the identification data body is set, and the corresponding identification data body is not deleted, so that when online is resumed, the identification data body does not need to be created again, and only the query permission needs to be modified.

On the basis of the above-described embodiment and the following-described embodiment, the present embodiment explains a process of dynamic identification and static identification conversion. Since the identification type is classified according to the update frequency and the safety level of the vehicle data, the identification type may be converted if the update frequency and the safety level of the vehicle data are changed. In the conversion process, the data identification system comprises a vehicle-mounted terminal and an enterprise node to which the vehicle-mounted terminal belongs. In the following, different identifier type conversion strategies are described in different cases by means of specific embodiments.

Conversion of dynamic identifier to static identifier

The dynamic identification data body is convenient for data updating, and the static identification data body is convenient for data query. Therefore, the embodiment performs the conversion of the identification type according to the updating and querying conditions of the identification data body.

Optionally, after the vehicle-mounted terminal creates the dynamic identifier and the dynamic identifier data body of the vehicle data, the method further includes the following steps:

step one, if the dynamic conversion condition is triggered, the vehicle-mounted terminal sends a dynamic conversion request and the vehicle data to the enterprise node.

Specifically, the dynamic identification and the dynamic identification data body are both stored in the vehicle-mounted terminal, so that the vehicle-mounted terminal monitors the updating and inquiring conditions of the dynamic identification data body and judges whether to trigger the dynamic conversion condition. The dynamic conversion condition refers to a trigger condition for converting the dynamic identifier into the static identifier.

Optionally, the dynamic transition condition comprises: the ratio of the number of updates to the number of queries within a set time period reaches a certain threshold; or the updating times in the set time interval are in an ascending trend, and the query times are in a descending trend; or the number of updates within a set period of time reaches a peak while the number of queries remains stationary, etc. The specific dynamic conversion condition may be set according to the requirement, and this embodiment is not limited.

And step two, if the dynamic conversion condition is triggered by the updating and inquiring conditions of the dynamic identification data body, the vehicle-mounted terminal sends a dynamic conversion request and the vehicle data to the enterprise node to which the vehicle-mounted terminal belongs.

And step three, the enterprise node responds to the dynamic conversion request, creates a static identification data body of the vehicle data, and modifies the identification type of the locally stored dynamic identification into a static identification. After the dynamic identification is created, when the data demand end inquires the identification, the static identification data body can be obtained through the enterprise node to which the dynamic identification belongs.

Optionally, after the enterprise node modifies the identifier type into a static identifier, sending a conversion completion response to the vehicle-mounted terminal; and the vehicle-mounted terminal responds to the conversion completion response and modifies the data type of the vehicle data into static data. After the identification type is modified, when the vehicle data is updated, the vehicle-mounted terminal requests the enterprise node to which the vehicle-mounted terminal belongs to update according to the updating strategy of the static data. Thus, the conversion from the dynamic identification to the static identification is realized.

In addition, besides the conversion of the identification types according to the updating and inquiring conditions of the identification data bodies, the identification type conversion can also be carried out according to the safety level of the identification data bodies. Optionally, the security level is prioritized over update and query cases.

Optionally, the determining, by the vehicle-mounted terminal, whether a dynamic conversion condition is satisfied according to the update and query conditions of the dynamic identification data volume includes: and if the security level of the dynamic identification data body is convertible, judging whether a dynamic conversion condition is met according to the updating and inquiring conditions of the dynamic identification data body.

The security level may be set by an operating user of the data distribution end. The security performance of the dynamic identifier is higher than that of the static identifier, and the dynamic identifier is allowed to be converted into the static identifier only when the security level is convertible. For dynamic data with high security requirements, the security level may be set to "non-convertible". Therefore, no matter how the updating and inquiring conditions of the dynamic identification data body are, the conversion of the identification types can not be carried out, and the dynamic identification data body is always stored locally.

(II) conversion of static data to dynamic data

Optionally, after the enterprise node creates the static identifier and the static identifier data volume of the vehicle data, the method further includes the following steps:

step one, the affiliated enterprise node judges whether to trigger a static conversion condition according to the updating and inquiring conditions of the static identification data body.

Specifically, the static identification and the static identification data body are both stored in the enterprise node, so that the enterprise node monitors the updating and inquiring conditions of the static identification data body and judges whether the static conversion condition is touched. The static conversion condition refers to a trigger condition for converting the static identifier into the dynamic identifier.

Optionally, the static transition condition comprises: the ratio of the query times to the update times in a set time period reaches a certain threshold; or the query times in the set time period are in an ascending trend, and the updating times are in a descending trend; or the number of queries within a set period of time reaches a peak while the number of updates remains steady, etc. The specific static conversion condition may be set according to the requirement, and this embodiment is not limited.

And secondly, if the static conversion condition is set out according to the updating and inquiring conditions of the static identification data body, the enterprise node requests the vehicle-mounted terminal to create the dynamic identification and the dynamic identification data body of the vehicle data. In a specific embodiment, the enterprise node sends a static conversion request to the vehicle-mounted terminal.

And step three, after the vehicle-mounted terminal creates the dynamic identification and the dynamic identification data body of the vehicle data, the enterprise node to which the vehicle-mounted terminal belongs deletes the static identification data body and modifies the identification type of the locally stored static identification into the dynamic identification.

In the foregoing specific embodiment, the vehicle-mounted terminal creates the dynamic identifier and the dynamic identifier data body of the vehicle data in response to the static conversion request, and sends a conversion completion response to the enterprise node to which the vehicle-mounted terminal belongs. After the dynamic identification is created, when the vehicle data is updated, the vehicle-mounted terminal can locally update the dynamic identification data body according to the updating strategy of the dynamic data.

And the affiliated enterprise node responds to the conversion completion response, deletes the static identification data body, and modifies the identification type of the locally stored static identification into a dynamic identification. After the type of the identifier is modified, when the data demand end inquires the identifier, the enterprise node which the identifier belongs to requests a dynamic identifier data body from the vehicle-mounted terminal according to the inquiry strategy of the dynamic identifier. Thus, the conversion from the dynamic identification to the static identification is realized.

According to the embodiment, the dynamic identification and the static identification are converted according to the query and update conditions and the security level of the identification data body, the respective advantages of the dynamic identification and the static identification are fully utilized, the whole network resources in the process of query and update of the identification are saved for the identification system, and the whole data call efficiency of the system is improved. It should be noted that the conversion condition may also be triggered by a user operating the in-vehicle terminal according to a requirement, and the conversion method after triggering the conversion condition is similar to the process described in this embodiment.
