Abstract：Based on the analysis of the IoT research, this paper propose the definition of the Internet of Things (IoT) for railway engineering, analyze the development demands of railway engineering construction informatization and the construction goal of the engineering IoT cloud platform. The paper first proposes the technical architecture, data processing architecture, and functional framework for the railway engineering IoT platform. Establishing a unified railway engineering IoT cloud platform provides a complete development platform and technical components to support the rapid access of diverse terminal equipment, thereby solving the problems about the perceived source at the construction site. In addition, the HASH encryption algorithm implements secure data transmission based on the MQTT protocol and achieves the unified collection, storage, forwarding and comprehensive analysis of railway infrastructure whole life cycle monitoring information by using flexible rule definition engines, dynamic and efficient streaming computing engines, and data pre-processing and filtering technologies. The construction processes make dynamic remote data collection, automatic judgment, closed-loop tracing, and intelligent decision-making to create management tools which provide a new information foundation platform for intelligent railway construction.
