Industrial data middleware is one of the basic software platforms of totally-domestic supervisory information system for plant level(SIS). Based on domestic software and hardware equipment

the fully autonomous and controllable high-performance industrial data middleware has become the backbone of power information security in China. On the basis of analyzing the commonly used middleware technology

the totallydomestic Rytong industrial data middleware developed by Xi'an Thermal Power Research Institute Co.

Ltd. is introduced in detail

focusing on its design ideas

system architecture and implementation of some key technologies.The Rytong industrial data middleware widely supports a variety of operating systems and hardware platforms

its database drive based on the plug-in mechanism can realize standardized data access

and multiple measurement point label routing policies and managed process pools can realize large-scale

high-speed and high-performance data access. The totally-domestic Rytong industrial data middleware has been successfully applied in the totallydomestic SIS demonstration project of Huaneng Group

and its characteristics of cross-platform

real-time and high scalability will provide strong technical support for construction of the future power informatization.
