Dual power supply type data server

Abstract

A dual power supply type data server comprises a power supply interface for supplying power to the data server, and an alternating-current dual power supply switching module, wherein one part of the input end of the alternating-current dual power supply switching module is connected to a commercial power interface, the other part of the input end of the alternating-current dual power supply switching module is connected to an inverted power supply, and the output end of the alternating-current dual power supply switching module is connected with the power supply interface; the inverted power supply comprises a storage battery and an inverter connected with the output end of the storage battery; and the output end of the inverter is connected with the alternating-current dual power supply switching module. When commercial power is normal, the commercial power interface supplies power to the data server and charges the storage battery; when the commercial power is abnormal, the storage battery inversely outputs 220V alternating-current to the data server; and two input power supplies, namely the commercial power and the inverted alternating-current output, can be automatically switched to each other, and switching interlocking is performed during switching to prevent inter-phase short circuit. The commercial power and the storage battery cooperate with a switching circuit, thereby providing a power supply system which is stable and reliable in working and is provided with a standby power supply for the data server; and the fact that the power still can be continuously supplied in a severe environment is ensured to prevent data loss.

Description

technical field [0001] The present invention relates to the field of data servers, in particular to a dual power supply data server. Background technique [0002] With the rapid development of computer science and technology in recent years, people have noticed more and more that the transactional business operations in the office are separated from the development of computers. With the maturity of network communication technology, computer technology and database technology, people have proposed a new concept of office automation. Usually the business of the office is mainly to process a large number of documents, draft documents, notices, various business texts, accept external documents for archiving, query documents, copy documents and other basic businesses. It also includes leading agencies to make decisions and issue instructions. In addition to personal exchanges, the deeper work is actually the collection, storage, retrieval, processing, and analysis of information...

Problems solved by technology

[0003] With the development of office automation, more project management in enterprises is also managed electronically. If the data server used for project management is powered off or the voltage is unstable during data processing, it may cause data loss.
