Detailed implementation manner

[0042] The following will further elaborate on the present application in conjunction with the attached Figure 1 - Attachment Figure 8 , and make a more detailed description of the present application.

[0043] The current mainstream tax control products mainly include the following three categories:

[0044] Firstly, embedded tax control devices such as tax control disks and tax UKs are combined with local invoicing software to support various offline invoicing scenarios; secondly, tax control servers and the supporting tax control keys and tax control server invoicing software, through the multi-tax control core board in the tax control server corresponding to the multi-tax number ability, and the invoice library / invoice pool design, realize the centralized management of thousands of invoicing outlets under dozens of subsidiaries; finally, various tax control disk groups and the supporting cloud platform and multi-platform invoicing front-ends.

[0045] Among them, the framework of the invoicing system for the tax control device disk group is as Figure 1 shown. It can be seen that the tax control disk group is connected to the cloud platform, as well as the invoicing PCs, mobile invoicing devices, and invoicing system servers of the user side through the Internet. With the help of the cloud platform, users can access the Internet of Things tax control disk group through various invoicing devices and perform tax control operations such as invoicing. The hardware framework of the tax control disk group is as Figure 2 shown, mainly including a network card, an industrial computer motherboard, a PCIE board, a USB controller, a multi-level USB HUB, and various embedded tax control devices used in supporting.

[0046] Since 2023, relevant departments have widely promoted the digital electronic invoice and its invoicing system across the country.

[0047] The current digital electronic invoicing system can be divided into the digital electronic invoicing system for large enterprises and the electronic tax bureau for small and medium-sized enterprises and individuals according to the types of tax-paying enterprises. The digital electronic invoicing system is executed online throughout the process. The core invoice data is pushed by the invoicing port of the large enterprise invoicing system, or small and medium-sized enterprises fill it in themselves on the electronic tax bureau web page based on the B / S architecture. The invoice data is generated on the tax bureau's background server and the result is returned to the tax-paying household side.

[0048] Currently, the three invoicing systems based on embedded tax control devices, tax control servers, and tax control disk groups are all widely used in the market. However, with the promotion of the new digital electronic invoicing system, the above three invoicing systems no longer meet the daily needs of users.

[0049] Compared with the traditional tax control system invoicing system, the digital electronic invoicing system no longer requires dedicated tax control devices to manage tax numbers one by one, nor does it support functions such as offline invoicing of dedicated tax control devices, generation of tax control codes, and storage of electronic invoice data.

[0050] However, while the digital electronic invoice is being promoted currently, the characteristics of high stability and offline usability of the tax control device system will still operate in parallel with the digital electronic invoice for some time, and there is also a need for supporting safe use based on new hardware devices in the future.

With the powerful encryption and decryption performance of the digital electronic PCIE encryption card 42, it can provide high-performance data communication, data storage encryption and decryption services for high-concurrency digital electronic invoicing operations, and ensure the security of the whole-process data.

[0094] The invoicing system based on the digital electronic tax control compatible disk group also supports the insertion of RAID encrypted storage. Currently, digital electronic invoices are different from the tax control invoicing system. There is an embedded tax control device 34 to ensure the security of the data storage in the invoicing process. Therefore, the digital electronic tax control compatible disk group supports RAID encrypted storage devices to ensure the secure storage of various invoice data and management data during the issuance of digital electronic invoices.

[0095] Currently, the invoicing system based on the digital electronic tax control compatible disk group needs to face the digital electronic platforms of tax bureaus in about two or three dozen provinces, municipalities, autonomous regions, production and construction corps, and cities specifically designated in the state plan across the country. The network situation is complex, and there are often problems such as the unified IP used by batch users being blocked due to improper operations or misoperations by individual users.

[0096] Currently, when enterprises use digital electronic invoicing services, which are different from the traditional tax control invoicing that supports offline operations, the whole process of digital electronic invoices requires continuous online connection to the digital electronic platform 9 of the tax bureau. The biggest pain point for enterprises is the uncontrollable local communication problems such as unstable network, failures of the digital electronic platform of the tax bureau, and the blocking of public network IPs.

[0097] The invoicing system based on the digital electronic tax control compatible disk group solves this problem by supporting the pre-issuance of digital electronic invoices. The invoicing instructions and data sent by enterprises are transmitted to the Internet of Things cloud platform 7 as pre-invoice requests in the first instance. The data public network communication is ensured through the digital electronic PCIE encryption card 42, the pre-opened data is securely stored through RAID encrypted storage, and at the same time, various types of traditional embedded tax control devices 34 are also supported to ensure the security of invoice data, management data, etc. during the digital electronic and tax control invoicing processes. The identity authentication with the data platform is ensured through the digital electronic password key, and the communication with the tax bureau is ensured through multiple network cards and IP switching.

[0098] All pre-invoicing requests are interacted with the digital electronic platform 9 of the tax bureau through the invoicing system based on the digital electronic tax control compatible disk group in an orderly manner according to the pre-configuration. The whole process is safe and controllable. When local communication problems occur, they wait in an orderly manner, poll and send, and return the results of successful execution, suspension waiting, or execution failure to the customer in a timely manner.

[0099] The invoicing system based on the compatibility of digital electronic tax control also supports multi-network card and multi-line network access, can be connected to different network operators, ensures automatic multi-IP switching, and protects the stability of the network communication of the invoicing system.

[0100] In terms of design, the digital electronic tax control compatible disk group can support various types of current mainstream hardware devices, and also provides a solid foundation for subsequent continuous optimization and expansion in software. Therefore, the digital electronic tax control compatible disk group has extremely high future operation prospects.

[0101] The invoicing system based on the digital electronic tax control compatible disk group can be directly obtained by directly upgrading the software and hardware of various types of tax control disk groups currently in operation, greatly reducing the software and hardware update costs for tax service enterprises in subsequent operations.
