CNNC Launches Two New Patents in the Field of Nuclear Instrument Control

[China Instrument Network Instrument R&D] Recently, the "CPCI Bus Chassis" and "Nuclear Power DCS Platform Test Device Based on Simulation System" applied for by China Nuclear Control System Engineering Co., Ltd. have been granted utility model patents granted by the State Intellectual Property Office of the People's Republic of China. certificate. Up to now, China Nuclear Power has obtained 16 national patents for nuclear instrumentation control.


It is reported that "CPCI Bus Chassis" is specially designed for CNNC to control the NicSys2000 platform product of non-safety level DCS products of its own brand nuclear power plant. The design of the chassis is novel and full of strong sense of science and technology. This product complies with the high-performance industrial computer bus standard and is highly open, highly reliable, and hot-swappable. In addition to this product can be widely used in communications, networking, computer telephony, but also for real-time system control, industrial automation, real-time data acquisition, military systems, such as the need for high-speed computing, intelligent transportation, aerospace, medical equipment, water and other modular and High reliability, long-term use of the application area. Because CPCI has higher bandwidth, it is also suitable for some high-speed data communication applications, including servers, routers, switches, and so on.

"A nuclear power DCS platform test device based on simulation system" can select a suitable process system to run a certain scale of actual projects on the DCS platform, and design test cases based on the system process requirements to achieve the DCS platform function and performance testing . During the design process of the nuclear power plant instrumentation system, repeated logic verification and parameter optimization are required. The platform tester has developed a variety of functional modules for simulation of different functions, including thermal-hydraulic calculation and control system simulation. Human-machine interface, etc. Each module is embedded in the simulation platform through the standard interface of the platform. The interface adopts the form of a standard dynamic link library. Based on the design verification simulation platform, a 1000MW PWR nuclear power plant engineering simulator was established, and parameters of the control system model were optimized and debugged.

The launch of the two new patents is conducive to China’s nuclear control and development of new products, creating a solid foundation for the future development of China’s nuclear instrumentation and control, and accelerating the pace of China’s nuclear power “going out”.
