Abstract

The invention relates to an independently-controlled earth leakage protection project management service system comprising a plurality of data servers connected by an internal network, a dual-power supply device, and a plurality of alternating-current earth leakage protection modules. The dual-power supply device consists of an alternating-current dual-power switching module and an inverter; one input terminal of the alternating-current dual-power switching module is connected with a commercial power interface and the other output terminal is connected with the inverter; and power interfaces of all data servers are connected to an output terminal of the alternating-current dual-power switching module by alternating-current earth leakage protection modules. According to the invention, the circuit switching is carried out based on cooperation of the commercial power and the storage battery and thus a power supply that works stably and reliably and has a standby power supply can be provided for the data servers, thereby preventing the data loss. Because earth leakage protection can be provided for each data server separately, the data server can maintain the power off state when an earth leakage phenomenon occurs at the data server, thereby avoiding an accident and preventing the work of other data servers from being influenced. Moreover, the structure of the system is simple and practicability is high.

Description

technical field [0001] The invention relates to the field of data servers, in particular to an individually controlled leakage protection project management service system. 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,...
