DETAILED DESCRIPTION

In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

The embodiments of the present application provide a product data query method, device and storage medium based on identity resolution, which are used to solve the following technical problem: how to enable different types of users to query only the relevant data corresponding to their own identities.

The technical solution proposed in the embodiments of the present application is described in detail below with reference to the accompanying drawings.

FIG1 is a flow chart of a product data query method based on identification resolution provided by an embodiment of the present application. As shown in FIG1 , a product data query method based on identification resolution provided by an embodiment of the present application specifically includes the following steps:

Step 101: Encode products added to the industrial Internet based on preset coding rules to determine the product identification code corresponding to the product.

In one embodiment of the present application, in order to realize the coding of products added to the industrial Internet, it is first necessary to use the identification resolution technology to register the product at the national secondary node. After the product is registered, the product can be encoded based on the preset coding rules after the product is produced or when it is added to the industrial Internet to determine the product identification code corresponding to the product.

Specifically, firstly, the product identification code prefix corresponding to the product is determined based on the product type and the product number of the product, then the user type to be operated corresponding to the product is determined, and based on the user type to be operated, the product identification code suffix corresponding to the product is determined.

It should be noted that in the embodiment of the present application, the prefix of the product identification code is a part used to distinguish different products, and the suffix of the product identification code is a part used to describe the user type corresponding to the product information that can be read based on the identification code.

In one embodiment of the present application, the type of user to be operated corresponding to the product is determined, and based on the type of user to be operated, the product identification code suffix corresponding to the product is determined, specifically including: determining the number of user types applying the industrial Internet, and based on the number of user types, determining the number of digits of the product identification code suffix; wherein the number of digits of the product identification code suffix is the same as the number of user types; based on the number of digits of the product identification code suffix, constructing an initial identification code suffix corresponding to the product identification code; wherein each digit in the initial identification code suffix is used to set a user identification value of the corresponding user type; determining the type of user to be operated corresponding to the product, and based on the type of user to be operated, setting the user identification value of the corresponding digit in the initial product identification code suffix to determine the product identification code suffix corresponding to the product.

In the embodiments of the present application, a detailed explanation is given through the following Example 1.

Example 1: There are four types of users who apply the industrial Internet: managers, quality inspectors, maintenance personnel, and users. The number of digits in the product identification code suffix is determined to be 4. If the identification code is a digital type, the initial identification code suffix of the product can be set to 0000. Assuming that the user identification values corresponding to the four types of users are 1, 2, 3, and 4 respectively, and the user types to be operated for a certain product are only managers and users, the product identification code suffix corresponding to the product can be set to 1004.

Further, after the product identification code prefix and the product identification code suffix are determined, the product identification code corresponding to the product is determined based on the product identification code prefix and the product identification code suffix.

It should also be noted that, after determining the product identification code, the embodiment of the present application can convert the product identification code into a barcode or a QR code and set it on the product for the user to identify the product identification code.

Step 102: Based on the product information of the product, construct a full information table of the product, and set data identification values for various types of data in the full information table.

In one embodiment of the present application, in order to enable a user to query product information based on a product identification code, it is also necessary to establish a connection between the product identification code and the product information.

Specifically, first determine the product information that can be queried based on the product identification code, and then build the corresponding full information table based on the product information. In order to achieve that different users in the product information can only query the data of the corresponding identity type, after determining the full information table, this application determines the user type to be operated corresponding to each type of data in the full information table; then, based on the user type to be operated corresponding to each type of data, set the data identification value for each type of data in the full information table.

It should be noted that the product information in the embodiment of the present application may include various product attribute data of the product and various operation tasks to be performed; the user identification value and the data identification value are in a one-to-one mapping relationship, and each type of data can correspond to multiple data identification values.

In one embodiment of the present application, in order to realize that the product information in the full information table can be queried by parsing the product identification code, the embodiment of the present application will store the full information table in the node database of the industrial Internet after constructing the full information table of the product; then, according to the storage address of the full information table in the node database, the storage address is bound to the product identification code and the storage address, so that the corresponding full information table can be determined to be queried when the product identification code is parsed.

Step 103: When the first user parses the product identification code, a parsing instruction sent by the first user is received and identified to determine the user identity information contained in the parsing instruction, and based on the user identity information, a first user identification value corresponding to the first user is determined.

In one embodiment of the present application, a product identification code is set on the product, and after the full information table is bound to the product identification code, if the first user parses the product identification code, a parsing instruction generated by the first user based on the product identification code is received, and then the first user identification value corresponding to the first user is determined according to the user identity information contained in the parsing instruction. It should be noted that in the embodiment of the present application, the user identity information includes the user's account information and the user's transmission address; the embodiment of the present application assigns different types of accounts to different types of users, and each type of account corresponds to a different user identification value. Therefore, the first user identification value corresponding to the first user can be determined based on the first user's account information.

Step 104: Match the first user identification value with the data identification values of various types of data in the full information table to read the to-be-read data corresponding to the first user.

In one embodiment of the present application, after determining the first user identification value corresponding to the first user based on the user identity information, it is first necessary to determine whether the first user has the right to read the product information of the product based on the product identification code.

Specifically, the first user identification value corresponding to the first user is matched with each digit of the product identification code suffix in sequence to determine whether there is a corresponding first user identification value; if it is determined that the corresponding first user identification value does not exist in the product identification code suffix, a notification of no authority to view is sent to the first user.

In the embodiments of the present application, the following Example 2 is used for detailed explanation. It should be noted that Example 2 is an extension of Example 1.

Example 2: Assuming that the first user identification value is 2, the user identification value is matched one by one with the four digits in the product identification code suffix "1004". Since the corresponding four digits do not match the first user identification value of 2, the first user has no authority to view the product information of the product, and a notification of no authority to view is sent to the first user.

In one embodiment of the present application, when it is determined that there is a corresponding first user identification value in the product identification code suffix, the first user identification value is matched with the data identification values of various types of data in the full information table to read the data to be read corresponding to the first user.

Specifically, a preset identification value comparison table is read, and based on the identification value comparison table, a first data identification value corresponding to the first user identification value is determined; based on the first data identification value, data of the type corresponding to the first data identification value is determined to be the data to be read; based on the user identity information contained in the parsing instruction, a transmission address of the first user is determined, and based on the transmission address, the data to be read is sent to the first user, so that the first user can read the data to be read.

Based on the same inventive concept, the embodiment of the present application also provides a product data query device based on identity resolution, and its internal structure is shown in FIG2 .
