METHOD AND INTERNET OF THINGS SYSTEM FOR SAFETY INSPECTION BASED ON SMART GAS GEOGRAPHIC INFORMATION SYSTEM

Method and Internet of Things system for safety inspection based on a smart gas geographic information system (GIS) are provided. The method comprises: determining a gridding result through performing gridding processing on a gas pipeline network; determining a required inspection area and an optional inspection area based on the gridding result; generating a target inspection route based on the required inspection area and the optional inspection area; determining an inspection plan based on the target inspection route; generating an inspection instruction based on the inspection plan; updating a gas pipeline grid graph based on inspection data after inspecting each inspection area; determining at least one failure possibility of the at least one node or the at least one edge through a failure possibility determination model; determining a grid safety score based on the at least one failure possibility, and determining an updated inspection plan based on the grid safety score.
