Description

Technical Field

[0001] The present invention belongs to the technical field of blockchain, and in particular relates to a departmental financial coordination management system and method based on blockchain. Background Art

[0002] With the rapid economic development, increasingly complex market environment and further deepening of corporate practice, higher requirements are put forward for the role of management accounting decision support. Inaccurate management accounting information will lead to wrong corporate decisions and seriously affect the company's operating efficiency. By reviewing previous studies, we found that the application of blockchain technology in the accounting field is mostly concentrated on the combination of blockchain with accounting, auditing and financial sharing centers, and mainly analyzes the feasibility of blockchain in these fields. There are few studies on blockchain technology and management accounting. The research on management accounting system is relatively mature, but most of it focuses on how management accounting designs and builds management accounting reporting systems, and how big data is combined with management accounting reporting systems.

[0003] In enterprises or universities, standardized financial management is of great significance to ensure the smooth progress of employees' work, the normal operation of enterprises or universities, and fairness. Therefore, managers analyze the financial activities between departments of enterprises or universities not only to correctly evaluate the past operating status of enterprises or universities, but more importantly, to predict the future development trend of enterprises or universities, analyze the future value of enterprises or universities, and provide a basis for financial forecasting, decision-making and control through financial analysis. Therefore, management and analysis of financial data to avoid financial shortages affecting the production arrangements of enterprises is also an indispensable part of financial data management. In addition, when managing financial data, the security level is low. Financial data is easily stolen or tampered with by illegal elements during transmission. Once a problem occurs, the responsibilities between departments are unclear and it is easy to shirk responsibility. Summary of the invention

[0004] The purpose of the present invention is to provide a departmental financial coordination management system and method based on blockchain, which solves the problems of insufficient supervision and low management efficiency of existing corporate financial management by processing corporate financial information on the chain and weighting different financial items to select administrators of corresponding levels for approval, generating corresponding financial full-process reports, and automatically determining the approving administrators based on the value of the assets.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions: The present invention is a departmental financial coordination management system based on blockchain, including a user layer, an application layer, a business layer, a network layer and a data layer; The user layer includes enterprise property personnel, enterprise management personnel, department heads and external supervisors of the enterprise; the enterprise property personnel are used to carry out daily operations of the management system; the enterprise management personnel are used to audit and monitor property work, and the department heads are used to apply for and issue property; the external supervisors of the enterprise are used to access and query the system through the external network or client; The application layer includes a data processing module, a data utilization module, a data visualization module and a user management module; the data processing module is used to upload, download, save and delete data; the data utilization module is used to provide users with data analysis, search and visualization services; the data visualization module is used to tabulate and draw data; the enterprise management personnel and enterprise property personnel perform user registration, deregistration, identity recognition and authority granting operations through the user management module, and optimize the enterprise property data processing workflow, and use the functions of the application layer to complete the control of enterprise operating costs; The business layer includes smart contracts and multiple clients; the smart contracts use an artificial intelligence review mechanism to analyze and review the data, and store the relevant data according to the business model; the smart contracts divide the relevant income and expenditure based on the type of enterprise, and generate a report on the income and expenditure, to assist the collection personnel in conducting contract evaluation on the related data; The network layer includes a data generation module, a data broadcast module, a node verification module, a block generation module and a data writing module; the network layer performs data transmission and verification by a P2P network; The data layer is used to provide data support for the integration of enterprise management accounting and financial accounting; the data layer includes a chain structure, blocks and a database, and encrypts and stores the received data information through operation logic.

[0006] As a preferred technical solution, the data processing module records the relevant information of each department as a node on the blockchain. After the property applied for by the department is approved by the enterprise management personnel, the system synchronizes the property information of each department to the blockchain network. When it is monitored that the property information of each department is abnormal or does not match the property data on the blockchain, the enterprise financial personnel will pull the departments involved into forming an emergency blockchain network.

[0007] As a preferred technical solution, the department head sends attribute registration requests, warehousing and storage requests, warehouse call and outbound requests, property consumption requests, transfer requests, and disposal and outbound requests to the company's property personnel through the system, generates blocks from the requests through the blockchain network, and sends all blocks to all blockchain nodes through the broadcast mechanism.

[0008] As a preferred technical solution, when the blockchain network requests to generate a block, it queries the HASH of the chain data this time through the blockchain network, digitally signs the HASH of the chain data this time and generates a block; the block is input and converted into blockchain language for broadcast to the entire network, and each node in the entire network uses its own backup account book to check and verify the information.

[0012] As a preferred technical solution, after the enterprise property personnel agree to the delivery of the property, the property information will be published on the blockchain. Then, each node on the blockchain can receive the property delivery information, and the property will be distributed by the enterprise management personnel, and the property distribution information will also be recorded on the blockchain.

[0013] As a preferred technical solution, the application layer workflow includes the following steps: Step 1: Sort out business processes and divide financial centers: The enterprise financial management personnel preset all financial processes, sort out the financial chain, divide the financial centers, and the business activities included in each financial center; Step 2, create a blockchain: design the block structure, sort out the creation cost management blockchain according to step 1, and ensure that the blocks in the blockchain correspond to the financial centers divided in step 1 one by one; Step 3: Financial fluctuation analysis: Financial fluctuation analysis establishes the cause-effect relationship between financial consumption and workload; Step 4: Hash value generation and conversion: Under blockchain technology, each property management corresponds to a Hash value, which is finally converted into a Merkle value and stored in the block header. The block body completes all records in the process of property flow; Step 5: Information collection and real-time monitoring of financial activities: Blockchain technology enables each block’s information to be transmitted through Merkle values, records the cost information of each financial center, and aggregates the Merkle values ​​of all blocks; Step 6. Reasons for financial fluctuations: Identify and measure the intensity and frequency of financial demand based on the criteria for allocating products by the financial center; Step 7: Feedback and continuous optimization: Use blockchain technology and computer technology to automatically generate financial cost information reports.

[0014] The present invention is a departmental financial coordination management method based on blockchain, comprising the following steps: Step S1: The enterprise property personnel enter the property categories to be stored and assign a unique designated number to the new property categories; Step S2: The department head submits a requisition form or / and a consumption form or / and a transfer form to the enterprise property personnel according to the property required by the department; Step S3: The department head generates blocks through the blockchain network and sends all blocks to all blockchain nodes through the broadcast mechanism; Step S4: The enterprise property personnel browse the node for approval and calculate the approval weight value; Step S5: The enterprise property personnel sends the information to the enterprise management personnel of the corresponding level according to the weight value; Step S6: After the enterprise manager approves the application, the enterprise property staff will issue the property to the enterprise manager and synchronize all data to the blockchain; Step S7: External supervisors of the enterprise supervise the data on the blockchain.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0021] In order to make the purpose, technical solution and advantages of this application clearer, the following Figure 1 The implementation methods of the present application are described in further detail.

[0022] Before introducing the embodiments of the present application, the blockchain technology is first described.

[0023] Blockchain can be applied in finance, accounting, education and other industries. In recent years, blockchain has been applied to practical problem solving by various industries due to its advantages. These industries hope to use the unique advantages of blockchain to solve industry problems and promote industrial innovation and upgrading. Accounting firms such as PricewaterhouseCoopers and Deloitte have established blockchain R&D centers, hoping to achieve the integration of blockchain and accounting in this way, thereby improving audit efficiency and user experience; IBM and Linux jointly developed the blockchain open source project Hyperledger and have entered the development stage.

[0024] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-3It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application. Embodiment 1

[0025] See also Figure 2 As shown, the present invention is a departmental financial coordination management system method based on blockchain, comprising the following steps: Step S1: The enterprise property personnel enter the property categories to be stored and assign a unique designated number to the new property categories; Step S2: The department head submits a receipt or / and a consumption or / and a transfer form to the enterprise property personnel according to the property required by the department; Step S3: The department head generates blocks through the blockchain network and sends all blocks to all blockchain nodes through the broadcast mechanism; Step S4: The enterprise property personnel browse the node for approval and calculate the approval weight value; Step S5: The enterprise property personnel sends the information to the enterprise management personnel of the corresponding level according to the weight value; Step S6: After the enterprise manager approves the application, the enterprise property staff will issue the property to the enterprise manager and synchronize all data to the blockchain; Step S7: The enterprise's external supervisors supervise the data on the blockchain.

[0026] The characteristics of blockchain technology are as follows: (1) Safety signs Blockchain technology is highly tamper-proof. In the network, all participants must authenticate the consistency of the data in each block. If you want to invade the block, you must tamper with the existing information of all participants at the same time. However, due to the large number of participants in the Internet, tampering is almost non-existent, so it can effectively protect data security.

[0027] Transparent Features The data blocks of the blockchain can be seen by all parties involved and published on the network without any secrecy, unless there is no block generated, and without the generation of blocks, the transaction cannot be verified. Therefore, all data is displayed through the blockchain, achieving information transparency and improving the trust of all parties.

[0028] Collaboration Features As a massive, borderless system of blocks, blockchain is not connected to other blocks in the same way. Therefore, blockchain allows people to collaborate on a secure basis when sharing any kind of transaction to create the next block.

[0029] Decentralized Features In theory, blockchain is equivalent to a central ledger system, but structurally, each node of the blockchain must authenticate its own account, so that even if a certain node changes, it will not have much impact on the entire system. According to the characteristics of blockchain, it is difficult to modify it unless you have more than 51% of the computing power. Therefore, no organization or individual can effectively control it, which is the so-called "decentralization." Embodiment 2

[0031] The data processing module records the relevant information of each department as a node on the blockchain. After the property applied for by the department is approved by the enterprise management, the system will synchronize the property information of each department to the blockchain network. When it is monitored that the property information of each department is abnormal or does not match the property data on the blockchain, the integrated enterprise property personnel will pull the departments involved into forming an emergency blockchain network.

[0032] Department heads send property registration requests, warehousing and storage requests, warehouse call-out requests, property consumption requests, transfer requests, and disposal and outbound requests to corporate property personnel through the system, generate blocks from the requests through the blockchain network, and send all blocks to all blockchain nodes through the broadcast mechanism.

[0033] When the blockchain network requests to generate a block, it queries the HASH of the chain data through the blockchain network, digitally signs the HASH of the chain data and generates a block; the block is input and converted into blockchain language for broadcast to the entire network. Each node in the entire network uses its own backup ledger to check and verify the information.

Reasons for financial fluctuations: Identify and measure the intensity and frequency of financial demand based on the criteria for allocating products by the financial center; Step 7: Feedback and continuous optimization: Use blockchain technology and computer technology to automatically generate financial cost information reports.

[0038] See also Figure 4 As shown in the figure, the system structure of the application layer is as follows: At the application layer, enterprises can take advantage of the integration of management accounting and financial accounting to use blockchain technology to complete cost optimization, risk control, profit and loss accounting, liquidity control and operational capacity control. Each block can rely on the data of the business department and the financial department for intelligent calculation and public disclosure, automatically generate corresponding reports, and assist the enterprise management in making operational decisions. In addition, the application of production costs is explained, and the production and operation practices of the enterprise are included. The integrated system of management accounting and financial accounting will monitor the actual operating costs of the enterprise through the relevant data information on the block, thereby effectively controlling the operating costs of the enterprise. Based on blockchain technology, enterprise decision makers can add data processing, data utilization and user management modules related to production costs to the platform according to actual needs. In detail, the data processing module has the functions of uploading, downloading, saving and deleting relevant data; the data information storage location can be customized according to user needs; the data utilization module can provide users with data analysis, search and visualization services, and data visualization refers to tabulation and drawing; corporate financial accounting personnel and management accounting personnel can optimize the corporate financial data processing workflow through user registration, deregistration, identity recognition, and authority granting functions in the user management module, and use the application layer functions to complete the control of corporate operating costs. After the introduction of blockchain, the integrated system of management accounting and financial accounting will become more flexible and rich, breaking the fixed format and fixed time accounting report form under the traditional financial management model. In this way, the integrated system of corporate management accounting and financial accounting combines traditional fixed format and time reports with non-fixed format and time reports, so that the timeliness of corporate accounting information is effectively guaranteed, and effectively assists company managers in making operational decisions.

[0039] There are different levels of enterprise managers, and different weight values ​​are set for enterprise managers of different levels. Different properties are set with different approval evaluation weight values. When approving property supplementary instructions, the property supplementary instructions are sent to the enterprise manager terminals of different levels according to the hierarchy, and are approved by enterprise managers at all levels. When an enterprise manager of a certain level approves it, the purchase review unit calculates the approval evaluation weight value of the current property to be purchased, and compares it with the approval evaluation weight value. When the approval evaluation weight value is greater than the approval evaluation weight value, there is no need to pass the approval instruction to the next level of enterprise manager; when the approval evaluation weight value is less than the approval evaluation weight value, the approval instruction needs to be passed to the next level of enterprise manager for approval by the next level of enterprise manager.

[0040] It is worth noting that in the above system embodiment, the various units included are only divided according to functional logic, but are not limited to the above division, as long as the corresponding functions can be achieved; in addition, the specific names of the functional units are only for the convenience of distinguishing each other, and are not used to limit the scope of protection of the present invention.

[0041] In addition, those skilled in the art can understand that all or part of the steps in the above-mentioned embodiments can be completed by instructing related hardware through a program, and the corresponding program can be stored in a computer-readable storage medium.
