Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. The components of the embodiments of the present application, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the present application, presented in the accompanying drawings, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.
BOM (Bill of materials) is an important carrier of product information of enterprises, and runs through a plurality of core links such as research and development, production, purchase, service and the like. There is a need for performing collaboration based on BOM, whether between links, departments, and employees in an enterprise, or between an enterprise and its upstream and downstream collaborating entities. In the related art, most of the processing, sharing and collaboration modes of the BOM are performed in the form of files, and common formats include excel, xml and the like. This mode is inefficient, has poor real-time and accuracy, and is accompanied by a significant amount of manual maintenance.
1. The BOM data is published in the form of API, and other cooperative departments and enterprises can download related data through the API or directly integrate with other systems. This model, while solving to some extent the problem of data synchronization between two parties, still faces several challenges:
a. only the synchronization result data: such as BOM data under a particular view, but cannot obtain its conversion history and conversion method. Generally speaking, the conversion method and the conversion process are internal algorithm components of enterprise information software and do not belong to BOM data components;
b. enterprises or departments above two collaborate simultaneously, and the efficiency is low: for example, when a design company, a manufacturer, and a supplier perform collaborative research and development and production based on BOM data of a specific commodity, API docking between each two is required, which generally results in too high system integration complexity and thus is difficult to implement;
c. data authority is difficult to manage and control: in some enterprises, the BOM data often includes core intellectual property data such as process, design, and the like, and is a key object of privacy protection. Data sharing based on the API can not realize flexible data authority control in a multi-party cooperative scene.
2. Another common mode is that a core enterprise leads to establish a platform for BOM cooperative work, and participants can log in the platform with their own account numbers to perform operations such as viewing, editing, converting, downloading and the like of BOM data, and can perform fine-grained authority control by an enterprise administrator. However, this method has the following disadvantages:
a. all data exist in a centralized platform, and the privacy protection problem of enterprise core data cannot be solved;
b. when one supplier needs to serve a plurality of core enterprises, the suppliers need to cooperate in different BOM design platforms, and the suppliers often provide the same products, so that the redundancy and the efficiency of data are reduced, and the problems of inconsistent data versions, reduced accuracy and the like often occur;
based on this, the embodiments of the present application provide a BOM data sharing method, a block chain server, and a computer readable storage medium, which can implement data sharing between two or more parties, and enable an authorized enterprise to acquire a BOM conversion mode, thereby facilitating the authorized enterprise to analyze and check the data conversion process.
The embodiment of the application provides a BOM data sharing method, which is applied to a block chain, wherein the block chain comprises a plurality of enterprise nodes, and the enterprise nodes are in butt joint with an enterprise business system.
The Enterprise business system includes a system for material Management of an Enterprise, such as a system that may include a Lifecycle Management (PLM) system, an Enterprise Resource Planning (ERP) system, a Computer Aided Process Planning (CAPP) system, and the like.
The enterprise nodes included on the blockchain are used for interfacing with the enterprise business system, and one enterprise node interfaces with one enterprise business system. The enterprise business system is a business execution main body, such as an enterprise node can also correspond to a department in an enterprise, and each department in the enterprise corresponds to a node, so that the material related business can be processed on a chain.
Referring to fig. 1, the method comprises the following steps:
step S102, responding to BOM conversion operation triggered by the enterprise business system, calling BOM structure data and the block link contract engine through the corresponding target enterprise node, and performing conversion processing on the BOM structure data based on the block link contract engine to obtain the BOM conversion data.
The BOM conversion operation triggered by the enterprise service system may be an operation in which a user performs BOM conversion through triggering on the enterprise service system. The target enterprise node may be a node corresponding to an enterprise business system initiating data sharing, such as a host plant node and a plurality of provider nodes in one example; in another example, nodes for various departments included by the enterprise may be included. On the block chain, each enterprise node can improve the problem of BOM data release through an API in the related technology through decentralized data sharing.
Because the actual BOM data is of a tree structure, and each node of the tree structure is a material or a process (and other possible elements), the BOM data of the tree structure used for conversion processing is represented by the BOM structure data.
When calling, the BOM structure data is pre-stored in the database on the chain, and may be called through the data identifier of the BOM data when the user triggers the enterprise service system, or may perform data search in other manners, such as SQL, which is only an example and is not limited specifically herein.
The block chain contract engine is an intelligent contract which is configured on the block chain and used for converting the BOM structure data, and the BOM structure data can be converted through the block chain contract engine to obtain the BOM conversion data.
And step S104, sharing the BOM conversion data obtained after the conversion processing to other enterprise nodes except the target enterprise node on the block chain.
When data sharing is performed, data sharing on the chain can be performed through nodes on the blockchain, in practical application, each node on the blockchain can perform conversion processing of data, and BOM conversion data after conversion processing of the node can also be uploaded to the chain for data sharing.
In an example, fig. 2 shows a schematic diagram of BOM data sharing between a host factory and a supplier, taking an example that an enterprise service system includes a PLM system, an ERP system, and a CAPP system, where each enterprise service system performs BOM processing respectively, the PLM system corresponds to a host factory node, the CAPP system corresponds to a supplier a node, the ERP system corresponds to a supplier B node, and the host factory node, the supplier a node, and the supplier B node perform data sharing (i.e., synchronization) in a chain.
The method for sharing the BOM data includes the steps of firstly responding to BOM conversion operation triggered by an enterprise business system, calling BOM structure data and a block chaining contract engine through a corresponding target enterprise node, carrying out conversion processing on the BOM structure data based on the block chaining contract engine to obtain the BOM conversion data, and sharing the BOM conversion data obtained after the conversion processing to other enterprise nodes except the target enterprise node on a block chain. According to the method, the BOM data is converted through the enterprise nodes included in the block chain, and the BOM data result and the conversion processing mode are shared on the chain, so that the BOM data sharing between two or more parties can be realized, the collaborative operation of the manufacturing processes such as production, design, purchase, maintenance and the like can be performed, the authorized enterprise can know the BOM conversion mode, and the authorized enterprise can analyze and check the data conversion process conveniently.
The above-described BOM data sharing method will be described in detail below.
First, before the BOM structure call is performed, the method according to the embodiment of the present application further includes:
step 1.1), chaining BOM original data, and analyzing the chained BOM original data through an enterprise node to obtain material information and a relation topological graph; wherein, the material information records corresponding specific information in the relational topological graph.
Step 1.2), building BOM structure data based on the relational topological graph;
and step 1.3), storing the material information in SQL data, storing the BOM structure data in a graph database, and storing the conversion parameters and the conversion processing instructions in a NoSQL database. The data processing method has the advantages that the processing requirements of different types of data can be met by respectively storing the data in different types of databases, and when the data are subsequently called, different data query methods are adopted for calling and storing the data, so that the data processing efficiency is improved.
In an alternative embodiment, referring to fig. 3, constructing BOM structure data on a chain may include the following two ways:
1. and (3) creating BOM structure data on the chain through BOM original data: the BOM data is directly transmitted to a block chain network, the BOM data is received by the block chain network, then the BOM data is analyzed in an intelligent contract in the block chain network, a bill of material and a relation graph are analyzed, after the analysis, whether the material exists in the block chain network or not is judged, if the material does not exist in the block chain network, the material is created, the bill of material is updated after the material is created, if the material exists in the block chain network, the bill of material is directly updated, and then BOM structural data is created and stored.
2. By uploading BOM relationship data, the existing material information on the associated chain is: and transmitting the BOM relation data into the block chain network, receiving the BOM relation data by the block chain network, and pointing to the existing bill of materials. And searching and binding corresponding materials in the contract, and updating BOM structure data to generate a final BOM structure.
When the created BOM structure data is stored in the chain, the BOM structure data may be converted by the block chain contract engine to obtain BOM conversion data, and in an optional implementation, the BOM conversion data may include conversion result data and a conversion processing instruction, that is, after the conversion processing is performed in the embodiment of the present application, the converted BOM result data may be obtained, and a conversion mode of the BOM result data obtained by converting the BOM structure data may also be obtained (that is, how to perform the conversion may be characterized). In specific implementation, the method may further include:
step 2.1), carrying out conversion processing on BOM data based on a conversion function pre-configured by the block chaining contract engine to obtain conversion result data; the conversion function pre-configured by the block chaining contract engine comprises conversion parameters, and the conversion parameters at least comprise one or more of BOM hierarchy, BOM type or conversion algorithm;
step 2.2), determining a conversion processing instruction based on the conversion parameter during conversion processing; the conversion processing instruction is used for representing a conversion processing mode of the BOM structure data.
For the above step 2.1), the data conversion process performed by the blockchain contract engine can be as shown in fig. 4, where the conversion function pre-configured by the blockchain contract engine isf(x) Shown in FIG. 4f EBOM to MBOM （id bom Args) is a transfer function that converts from a design BOM (i.e., EBOM) to a manufacturing BOM (i.e., MBOM), wherein,id bom the data identification of the BOM structure data is shown, args is a conversion parameter, and the conversion parameter at least comprises one or more of BOM levels, BOM types or conversion algorithms, wherein the BOM levels are used for representing the hierarchical relation of structures among assemblies, components, parts and raw materials of products, the BOM types comprise engineering BOMs, planning BOMs, design BOMs, manufacturing BOMs, client BOMs, maintenance BOMs, sales BOMs, cost BOMs and purchase BOMs, and the conversion algorithms can comprise recursion, intersection, union, tree data structure operation and the like.
For the step 2.2), because the conversion parameters called by different data conversion requirements during data conversion processing are different, when data conversion processing is performed according to actual requirements, the conversion parameters used during conversion processing can be recorded to obtain a conversion processing instruction, so that the conversion processing mode of the BOM structure data can be determined according to the conversion processing instruction.
In an optional embodiment, in order to improve efficiency of BOM data processing, such that a dedicated instruction set for BOM processing is configured on a blockchain, the blockchain contract engine may include a BOM processing engine, where the BOM processing engine includes a BOM processing instruction set constructed based on the blockchain contract engine, and the instruction set includes at least a set operation and/or a tree data structure operation, where the set operation includes at least one or more of the following instructions: intersection, union, complement and set comparison are obtained, and the tree data structure operation at least comprises one or more of the following instructions: recursive traversal, depth/breadth search, sorting, reverse order, pruning. For ease of understanding, fig. 5 is a schematic diagram of a data transformation performed by a block chaining contract engine and a BOM processing engine, wherein the BOM processing engine relies on a general instruction set of the contract engine and performs encapsulation based thereon to form a special instruction set for BOM data processing. The instruction set should include commonly used BOM data processing algorithms such as intersect, union, complement, set comparison, recursive traversal, depth/breadth search, sort, reverse order, branch reduction, etc. In practical application, the performance optimization of the special instruction set can be performed by combining with a contract engine which is actually used, and BOM data processing is accelerated. Because the processing function, the BOM data and the like are stored in the account book, the transmission and the sharing can be carried out by utilizing a block chain native mechanism.
Considering that in actual business, one supplier needs to serve multiple enterprises, the BOM data usually includes core data such as process and design, and if multi-party data sharing is performed based on the API, the risk of privacy disclosure exists, and flexible data authority control cannot be performed. Therefore, in an alternative embodiment, the above-mentioned blockchain contracting engine is configured with an encryption function, the encryption function includes a private data filtering parameter, and the encryption function is used for performing encryption processing on the conversion function.
For ease of understanding, with reference to FIG. 6, the encryption function isg(x) Privacy filter parameter offiltersConfigurable policies for filtering private data, such as: the material or process with the particular label can be filtered. If the BOM contains sensitive data, such as key process in PBOM/MBOM, etc., then the encryption function g (x) can be added based on the above function f (x), according to the configuration ruleThe critical data is encrypted. In an optional embodiment, on the basis of the data conversion processing performed by the blockchain contract engine or the BOM processing engine, the BOM structure data may be filtered based on the private data filtering parameter of the encryption function, so as to filter out the private data in the BOM structure data, and the private data is subjected to encryption conversion processing based on the blockchain contract engine configured with the encryption function, so as to obtain encryption conversion result data, so that the encryption conversion result data is shared to the authorized enterprise node.
In addition, the data can be encrypted, and the data processing mode can be encrypted, when the method is specifically implemented, an encryption function can be loaded to a trusted execution environment, and the conversion result data and the conversion processing instruction are encrypted based on the encryption function to obtain encrypted conversion data, so that the encrypted conversion result data can be shared to an authorized enterprise node; wherein the encryption conversion data includes encryption conversion result data and an encryption conversion processing instruction.
In an example, if the business also performs privacy protection on the BOM conversion function f (x) to be opened to only a part of the business, the function g (x) may be encrypted and stored in the database, and loaded into the trusted execution environment for execution, and the specific flow is shown in fig. 7.
In order to further include data privacy, in an optional embodiment, the data may be converted and shared through secure multiparty computing, and the method further includes:
performing disassembly processing on the BOM structure data to obtain a plurality of BOM subdata; respectively stored in different enterprise nodes;
distributing the BOM subdata to a plurality of enterprise nodes respectively;
and respectively carrying out safe multi-party calculation on the corresponding BOM subdata based on the block linkage contract engines corresponding to the plurality of enterprise nodes, and combining and sharing multi-party calculation results.
For convenience of understanding, taking data conversion processing as an intersection as an example for explanation, referring to fig. 8, a design company, a supplier, and a core enterprise respectively store part of BOM data, that is, the above-mentioned BOM subdata, and through secure multiparty computing, the requirements of joint computing and collaborative design can be realized on the basis of not revealing private data, so as to further protect data privacy.
In summary, the methods for loading and executing the BOM conversion function in the block chain intelligent contract include the following:
1. the function is directly coded and executed in the contract;
2. storing a function plaintext in a database, and carrying out hot loading and execution when the function plaintext needs to be used;
3. the function encryption is stored in a database and is loaded to a trusted execution environment for execution when in need of use;
4. the function is divided into a plurality of modules, the modules are respectively stored in the blockchain nodes of different enterprises, and the modules are respectively loaded and perform safe multi-party calculation when in use.
Further, in order to improve transmission efficiency, in an optional implementation manner, when the BOM conversion data obtained after the conversion processing is shared to other enterprise nodes except the target enterprise node on the block chain, the conversion result data may be first disassembled to obtain BOM point data and BOM side data, and then the BOM point data and BOM side data are distributed through a P2P transmission protocol, so that the conversion result data obtained after the conversion processing is shared to other enterprise nodes except the target enterprise node on the block chain.
By adopting P2P for network distribution after disassembly, network congestion caused by concurrent downloading of full BOM data from a centralized server or platform can be avoided.
