The tax control panel (also called "tax control server") is a special tax control device, which was developed according to State Taxation Administration of The People's Republic of China's "Technical Specification for Tax Control Panel". The tax control panel is divided into single tax number tax control server and multi-tax number tax control server.

1 Introduction

The enhanced version of tax control panel (also called "tax control server") is a special tax control device, which is developed in full accordance with State Taxation Administration of The People's Republic of China's "Technical Specification for Tax Control Panel". The product is divided into single tax number tax control server and multi-tax number tax control server.

In line with the national standard GB 18240[ 1], SSF44 special tax control algorithm can realize the functions of tax control code calculation, invoice electronic information management, safe storage of invoice details and real-time clock.

The billing speed of each tax number is not less than 50 sheets per second, and it can support 200 billing terminals at the same time. Single server stores invoice details1t. It is suitable for group enterprises or companies with large billing volume, scattered billing points and complicated tax-related affairs.

2 business performance

1, technical innovation: separating the operation, signature and storage functions of the core board not only expands the storage capacity but also obviously improves the billing speed, which can reach 50 sheets /s (in the test environment, it can reach 150 sheets /s at the highest, and there is no pressure for real-time multi-user high concurrent billing or centralized batch billing at the end of the month);

2, high concurrency, each tax number can support 200 user billing terminals (single tax number server can support 600 billing terminals);

3. The storage capacity of invoice details is as high as 1T, which can store 10 billion electronic invoices, and can be expanded according to customer requirements.

Tax control hardware integration

1, centralized deployment of tax-controlled server equipment, which can realize independent deployment or mixed deployment of special hardware at provincial, prefecture and county levels according to the needs of enterprises, which is convenient for operation, maintenance and management;

2. Support for multiple tax numbers and billing terminals will reduce the number of tax control hardware and reduce the failure rate by centralized storage of tax-related data.

_ reliability

1, high reliability, supporting 7*24 hours continuous and stable operation;

2. The data of the tax control server is stored on the hard disk, and RAID mode is adopted. Damaging a hard disk will not cause data loss, so it can be replaced in time;

3. If the disaster recovery scheme of one master and one standby is adopted, the business continuity will be realized to the greatest extent. If there is a backup, the serious situation that the core board cannot be invoiced during the re-issuance period will be avoided.

openness

1, can provide billing service interface and terminal plug-in, and realize interconnection with banking system;

2. Customize the development of interface functions according to the needs of enterprises, for example, realize the linkage with the heavy control system.
