Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing priority management systems (PMS) in nuclear power plants require extensive hard-wired connections to receive control instructions from different safety classes, leading to inconvenient engineering implementation and increased complexity.
Innovation Solution
The integration of hard-wired interfaces, a safety class communication interface, and a non-safety class communication interface on a priority management device allows for direct reception of control instructions from various safety classes, eliminating the need for extensive hard-wiring and enhancing engineering applicability by establishing redundant communication links.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hard-wired interfaces are used to receive control instructions from different safety classes, then the system can ensure reliable instruction transmission, but the engineering implementation becomes inconvenient and the system complexity increases
Solution Approach 1:
The patent introduces a communication interface as an intermediary component between the priority management device and external systems. This communication interface converts communication protocols and transmits instructions wirelessly, eliminating the need for extensive hard-wired connections while maintaining reliable instruction transmission from different safety classes (1E, 1+, 2, 3) to the priority management device
2Adaptability or versatility
If extensive hard-wired connections are used to connect non-safety class systems to safety class systems, then control instructions can be transmitted, but cabinet space is occupied and implementation becomes extremely inconvenient
Solution Approach 1:
The patent replaces the mechanical hard-wired connection system with a wireless communication system. The communication interface receives control instructions wirelessly from non-safety class systems (NC-DCS) and transmits them to the priority management device, eliminating the need for physical hard-wired connections across cabinet spaces while maintaining system compatibility across different safety classes
3Device complexity
If multiple communication interfaces are integrated on a single priority management device, then the system can receive instructions from various safety classes without extensive hard-wiring, but the device complexity increases
Solution Approach 1:
The patent implements a multi-functional communication interface that can handle multiple communication protocols and support instructions from various safety classes (1E, 1+, 2, 3) through a single integrated device. The communication interface is designed to be universally compatible with different safety class systems, allowing the priority management device to receive and process control instructions from diverse sources without requiring separate dedicated interfaces for each safety class

AI summary
Embodiments of the present disclosure provide a nuclear power plant priority management system. The nuclear power plant priority management system includes a priority management device, which is connected with hard-wired interfaces and a safety class instruction interface. The priority management device is further connected with a non-safety class communication interface via hard-wired interfaces, and the non-safety class communication interface is configured for connecting with a non-safety class system and receiving non-safety class device level control instructions from the non-safety class system. The nuclear power plant priority management system integrates hard-wired interfaces, a safety class instruction interface, and a non-safety class communication interface to facilitate in receiving control instructions from various safety class systems, providing favorable engineering applicability. Moreover, by directly connecting the non-safety class communication interface and the non-safety class system, there is no requirement of connecting a large amount of hardwire, so that the usability of the system in engineering implementation is greatly improved.
