Research On Application Of IOT In The Field Of Safety Monitoring For Railway

With the leapfrog development of high-speed railway, the safety issue of railway transportation is more and more apparent. Because of great passenger capacity and high speed, once the accident occurs, it will lead to serious consequences. Therefore, there is important meaning to improve the railway safety monitoring level by building a real-time, reliable, accurate railway safety monitoring system. Internet of Things (IOT) has the characteristic of overall sensing, reliable transmission and intelligent computing. Will the IOT application in the field of railway safety monitoring, the requirements of intelligent monitoring to mass information can be satisfied and the efficiency of railway safety monitoring and warning can greatly improve.The paper introduces content related to the system of the railway safety monitoring and theory of the Internet of Things, and analyzes the key technologies of IOT in the field of railway safety monitoring. On this basis, the paper builds an application model of IOT in the field of safety monitoring for railway, and describes the model in detail from feasibility of constructing, functional structure and layer structure, to achieve intelligent monitoring for railway safety. In order to analyze the application model of IOT better, according to model, the paper makes a further analysis to the application on information sensing, information transmission, information processing of IOT technology in the field of railway safety monitoring. Finally, this paper summarizes and analyzes the challenges and countermeasures of the model application, indirectly enrich the design of the model as well.The main value of this paper is that it applies technologies of IOT in the field of railway safety monitoring, and builds the IOT application model of railway safety monitoring. From functional architecture, the model is divided into security supervisory and control and security management. From the layer architecture, the model is divided into perception layer, network layer and application layer. What's more, by researching on IOT technology in information sensing, information transmission and information processing, to make the railway safety monitoring more intelligent and reliable and make contributions to the application model of IOT as well.
