FPGA-based nuclear power plant safety level instrument control system with configuration function and control method thereof

Abstract

The invention discloses an FPGA-based nuclear power plant safety level instrument control system with a configuration function and a control method thereof. The nuclear power plant safety level instrument control system comprises an FPGA main control chip. The FPGA main control chip comprises a Block-RAM module which is used for storing data including the configuration data converted by the DCS function diagram; a basic application function module which is used for executing the functions on the DCS function diagram; and a main control logic module which is used for calling the data from the Block-RAM module and controling the basic application function module to use the data to execute the functions on the DCS function diagram. According to the FPGA-based nuclear power plant safety levelinstrument control system with the configuration function and the control method thereof, the development speed of the engineering project can be greatly enhanced, the technical threshold of the workpersonnel can be reduced, the accuracy of project execution can be improved and human errors can be reduced.

Description

technical field [0001] The present disclosure relates to the technical field of digital instrumentation and control, in particular to a programmable gate array (FPGA)-based safety-level instrumentation and control system and method for nuclear power plants with configuration functions. Background technique [0002] FPGA technology breaks the sequential execution mode, can process more logic in parallel on hardware, and processes large-scale and complex logic much faster than microprocessor technologies such as CPU. On the hardware interface (input and output pins), a large number of programmable pins are provided, the response time is fast, and professional design can be carried out according to user needs. The FPGA circuit is a real hardware running process. During the running process of the operating system and application software of the CPU processor, multi-process and multi-task shared memory, registers, arithmetic units, controllers and other hardware resources are div...

AI Technical Summary

Problems solved by technology

Although FPGA technology is better than CPU technology in terms of reliability, ease of verification, and security, it is still weak in terms of human-computer interaction.

[0004] The configuration scheme of the safety-level instrument and control system of nuclear power plants based on CPU technology is a mature scheme, but there is no configuration scheme for the instrument and control system based on FPGA technology on the market.
