针对莫高窟在保护利用数据传输过程中出现的问题与发展趋势,提出了利用无线网络深度覆盖技术构建数据传输平台,解决莫高窟大型洞窟内保护利用数据无法传输的问题。为构建实用性强的传输平台,采取了如下措施。首先,针对莫高窟保护利用各项业务数据采集、传输模式、传输机制等各阶段特点,提出了基于无线网络深度覆盖技术构建数据传输试验平台的需求;其次,设计了试验平台构建方案,依据莫高窟洞窟分布与建筑形制确定了试验平台构建位置。结合莫高窟目前无线网络覆盖现状,通过选型分析确定了无线网络深度覆盖关键技术,并应用该技术构建试验平台;最后,对试验平台无线信号覆盖范围、信号强度、传输性能、安全性等进行验证,确保数据传输的完整性与连续性。此试验平台已运行一年有余,应用效果良好。

Considering the data transmission problems and developmental trends for the conservation and utilization of Mogao Grottoes,it was proposed to use wireless network deep coverage technology to build a data transmission platform to solve the problem that conservation and utilization data could not be transmitted in large caves of Mogao Grottoes.In order to build a robust transmission platform,we took the following measures:first,depending on the characteristics of the various operational data collection methods,transmission modes and transmission mechanisms,etc.for the conservation and utilization of Mogao Grottoes,we proposed requirements for building a data transmission trial platform based on wireless network deep coverage technology;second,we designed a trial platform,with its location being determined in accordance with the distribution and architectural shape of Mogao Grottoes,and in combination with the current situation of wireless network coverage in Mogao Grottoes,the key technology of wireless network deep coverage was determined through model selection analysis,and the technology was applied to build a trial platform;finally,the wireless signal coverage,signal strength,transmission performance and security of the trial platform were verified to ensure the integrity and continuity of data transmission.This trial platform has been running for more than one year with good results.
