摘要
在国内外物联网研究的基础上,提出铁路工程物联网定义,分析当前铁路工程建设信息化发展需求和工程物联网云平台建设目标,首次提出铁路工程物联网平台的技术架构、数据处理架构和功能框架,建立铁路工程建设统一的物联网云平台,提供完整的开发平台和技术组件,支持多样化的终端设备快速接入,解决工程现场感知源头问题;利用HASH加密算法实现基于MQTT协议的安全数据传输,利用灵活的规则定义引擎、动态高效的流式计算引擎、数据装载的预处理过滤技术,实现铁路基础设施全生命周期监控监测信息的统一采集、存储、转发和综合分析,为施工现场动态信息的远程采集、自动研判、闭环追溯和智能决策提供管理手段,为铁路智能建造提供新的信息化基础平台。
Based on the research of Internet of Things in China and abroad,the definition of Internet of Things for railway engineering was brought up.The current development requirements for digitalization of railway engineering construction and the construction goal of Internet of Things cloud platform for engineering were analyzed.The technical architecture,data processing architecture,and functional framework of Internet of Things platform for railway engineering were put forward for the first time.A unified Internet of Things cloud platform for the construction of railway engineering was established;the complete development platform and technical components were provided.The rapid access to diversified terminal equipment was supported,and the problems of the perceived source at the engineering site were solved.Secure data transmission based on MQTT protocol was realized by using HASH encryption algorithm,and unified collection,storage,forwarding and comprehensive analysis of monitoring information in the full life cycle of railway infrastructure were realized through flexible rule definition engine,dynamic and efficient stream computing engine,and pre-processing and filtering technology of data loading,aiming to provide management tools for remote collection,automatic research and evaluation,closed-loop tracing,and intelligent decision-making of dynamic information at the construction site,and to provide a new information-based platform for the intelligent construction of railways.
