Wi-Fi、LTE、UWB等技术在大亚湾核电站应用的可行性分析

Feasibility Analysis of the Application of Wi-Fi, LTE and UWB Technologies in Daya Bay Nuclear Power Station

大亚湾核电站目前使用的通讯技术为无线寻呼技术,存在技术落后、维护难度大的问题,且该技术只能单向寻呼,不能建立双向实时连接,极大降低了工作效率,亟需改进。Wi-Fi、LTE、UWB等成熟无线通讯技术具有易于维护、双向数据传输的优点,为上述问题提供了良好的解决方案。论文首先对大亚湾核电站重要敏感区域进行了电磁兼容测试,其次调研了国内外核电站现有的无线通讯技术概况,最后在此基础上探究了上述几种无线通讯技术在大亚湾核电站应用的可行性。分析结果表明:在核电站重要敏感区域部署UWB基站,其余地区部署LTE微基站以替代无线寻呼系统是一种可行的方案。

Daya Bay Nuclear Power Station uses the wireless paging technology for communication currently, which is backward technology and hard to maintain; meanwhile this technology can only establish one-way connection rather than two-way real-time connection, which greatly reduces the work efficiency and needs to be improved. Wi-Fi, LTE and UWB technologies have advantages of easy maintenance and two-way data transmission which provide a good solution for solving above-mentioned problems. We investigated domestic and foreign nuclear power stations about wireless communication technology they use and analyzed the feasibility of the several above-mentioned wireless communication technologies on the basis of the EMC test results in the important and sensitive areas in Daya Bay Nuclear Power Station. The analytic results show that it is feasible to deploy UWB base station in important and sensitive areas, and to deploy LTE micro base station in the rest areas instead of wireless paging system in Daya Bay Nuclear Power Station.
