摘要
核电站环境监测领域包括陆上和海域两部分,监测设备分布十分分散。设备采集数据通过有线和无线传输的方式送到电站对应系统的中央站监控,其无线传输的方式随着社会科技的发展而有明显的技术改变。虽然第五代移动通信技术(5G)建设尚处于初步阶段,但考虑核电站建造的长周期以及我国5G建设的规划,有必要对5G技术在核电站环境监测系统中的应用提出探讨。通过介绍核电站环境监测系统的功能以及5G技术三个典型特征,提出了5G技术在核电站环境监测系统上的可用场景,分析了借助5G技术在实现核电站环境监测系统功能优化、减轻工作人员工作量和辐射暴露风险等方面的可行性。同时,从冗余无线通信手段提高环境监测系统的可用性出发,分析了5G通信与北斗、WiFi通信技术联合组网方案。对核电站在信息安全保护方面的要求和5G技术在信息安全上的防御措施进行了讨论,建立了基于5G通信技术的环境监测系统的逻辑架构和网络架构。该研究为核电站环境监测系统如何应用5G先进通信技术提供了思路框架,也提出了充分实现5G应用场景面临的挑战。
The environmental monitoring field of nuclear power plant includes land and sea areas,and the monitoring equipment is very dispersed.The data collected by the equipment is sent to the central station of the corresponding system of the power station for monitoring through wired and wireless transmission.With the development of social science and technology,the mode of wireless transmission has changed significantly.Although the construction of the 5th generation mobile communication technology(5G)is still in the preliminary stage,considering the long construction period of nuclear power plants and the planning of China’s 5G construction,it is necessary to discuss the application of 5G technology in the environmental monitoring system of nuclear power plants.By introducing the functions of nuclear power plant environmental monitoring system and the three typical characteristics of 5G technology,the available scenarios of 5G technology in nuclear power plant environmental monitoring system are proposed,and the feasibility of realizing the function optimization of nuclear power plant environmental monitoring system,reducing the workload of workers and radiation exposure risk with the help of 5G technology is analyzed.At the same time,from the perspective of redundant wireless communication means to improve the availability of environmental monitoring system,the joint networking scheme of 5G communication,BeiDou and WiFi communication technology is analyzed.The requirements of information security protection of nuclear power plants and the defense measures of 5G technology in information security are discussed,and the logic architecture and network architecture of the environment monitoring system based on 5G communication technology are established.This study provides a framework for how to apply 5G advanced communication technology to the environmental monitoring system of nuclear power plants,and also puts forward the challenges to fully realize 5G application scenarios.
