Title: DISTRIBUTED REAL-TIME DATA SERVER
Abstract:
Provided in the present invention is a distributed real-time data server. The server comprises a gateway, RTU, production database, OPC communication interface, data interface, firewall system, control system, and computation system. The data interface comprises serial bus interfaces, such as A/D analog magnitude acquisition, D/A analog control signal output, I/O on-off magnitude monitoring and control, RS-485, and RS-422. The server further comprises an industrial real-time database and data acquisition unit therein. The server is connected to the cloud via an Ethernet network, and pushes real-time data in the database to the cloud. A built-in web server enables users to directly access the distributed real-time data server via a browser to check real-time data and configuration information of the server. The present invention significantly improves real-time operation of data, enable efficient usage of the gateway and RTU, lowers the loads of networks and a central server, reduces security risks of network communication, ensures network security, and further compacts a system structure to create a flat structure.
