PI (plant information system) real-time database interface system

The invention discloses a PI (plant information system) real-time database interface system, which comprises a server (3), a first physical network card (4) and a second physical network card (5), wherein the server (3) is used for configuring a first virtual server (31), a plurality of second virtual servers (32), a first virtual switch (33) and a second virtual switch (34), the plurality of second virtual servers are connected with a data collecting system (2) through the second virtual switch and the second physical network card, and are used for collecting data information collected by the data collecting system, the first virtual server is connected with each second virtual server through the first virtual switch, and is used for receiving the data information, and the first virtual server is also connected with a PI real-time database system (1) through the first physical network card, and is used for sending the data information to the PI real-time database system. The PI real-time database interface system uses the existing server for configuring the virtual servers and the virtual switches, and the use of physical interface machines can be reduced.
