Discussion on Dynamic Early Warning System for City Gas Pipeline Risks Based on GIS and GPS
To reduce the occurrence of gas accidents,this paper constructs a reasonable regional risk index system for gas pipelines,visualises the risk level based on GIS to form a risk map,combines GPS positioning technology to locate the time,location and extent of gas leaks,and applies Internet of Things technology to collect accidental disaster information.A mobile phone APP is used as a medium for the public to send hazard information to users,residential properties,firefighters and nearby personnel.According to the APP real-time feedback to update the risk database,layer information is added and updated on the basic geographic information platform to meet the needs of different users for spatial geographic information and risk control,to reduce or eliminate safety hazards.it is conducive to improving the anti-risk capacity of the system and ensuring the safety of people's lives.
