Abstract
In order to analyze the environmental factors affecting the whole life cycle of railway equipment more comprehensively and effectively,and fill the gaps of railway outdoor environmental monitoring,this paper presents the deployment of indoor and outdoor environmental monitoring systems based on POE and NB-IoT in view of the limitations of existing railway environmental monitoring.The indoor environmental monitoring of POE mode adds dust,air pressure,noise,and carbon dioxide parameter monitoring,with simple and efficient system deployment,and low maintenance cost and system failure rate,which is conducive to the smooth upgrade of equipment in the later stage.The outdoor environmental monitoring of NB-IoT mode achieves innovative introduction of roadbed fill temperature and humidity,conductivity,rail temperature,vibration,and displacement parameter monitoring.Additionally,the indoor and outdoor environmental monitoring data are displayed in the form of indoor 3D images and outdoor equipment graphics.The proposed system features high-level integration,low price,low power consumption,and full coverage,which is suitable for multi-station,complex environmental scenarios in railways.关键词
