Problems solved by technology

However, there are many potential faults in software, and it is difficult to find and solve all these faults
Therefore, software-based microprocessors are also prone to common-mode failures, resulting in the failure of redundant equipment and diverse backups originally set up to improve reliability in the instrumentation and control system.

Abstract

The invention is a hardware architecture of a nuclear power plant diversity protection system based on FPGA, the technical problem to be solved is to avoid potential risks caused by software common mode failure, and belongs to the field of industrial automatic control. It is characterized in that: the card piece includes an analog quantity input card, a logic processing card, a digital quantity input / output card and a communication card, and the card piece all use FPGA as a logic processing element; the analog quantity input card and the digital quantity input / output card pass through the Signal transmission line and logic processing card carry out data transmission; analog input card, digital input / output card, logic processing card, host computer and display device carry out data transmission through signal transmission line and communication card respectively. The present invention overcomes the potential risk brought by software common mode failure, and improves the reliability of the nuclear power plant instrumentation and control system. At the same time, it can also perform self-diagnosis, real-time monitoring, parameter setting and online channel testing of the card. The flexible card configuration ensures the scalability and integrity of the entire hardware platform.

Description

technical field [0001] The invention belongs to the field of industrial monitoring and automatic control, and relates to a hardware platform architecture for a nuclear power plant diversity protection system. Background technique [0002] In the instrument and control system of nuclear power plants, especially in the protection system of nuclear power plants, multi-level, multi-channel, and multi-redundant equipment are often set up to ensure the reliability of the entire protection system. In order to avoid the risks brought by module faults, the nuclear power plant has also set up a diversity protection system, which uses equipment, principles and structures that are diverse with the protection system to realize the backup of the protection function of the nuclear power plant. The early diversity protection system of nuclear power plants used analog technology. With the requirement of digitalization of nuclear power plant instrumentation and control equipment, a digital di...
