Chemical material leakage alarm-providing system and chemical material leakage alarm-providing method

A chemical material leakage alarm-providing method of detecting chemical material leakage in a monitoring area and providing a user alert, the chemical material leakage alarm-providing method comprising:

• specifying a plurality of target detection areas based on three-dimensional space modeling data for the monitoring area;
• photographing a first target detection area and a second target detection area among a plurality of target detection areas by controlling an image camera;
• determining a first position of the image camera that captures images of the first target detection area and the second target detection area without overlapping each other;
• specifying a point of chemical material leakage by the image camera analyzing an image in which the first target detection area and the second target detection area, captured at the first position, do not overlap;
• determining a second position of a chemical material-detecting device so that the chemical material detection device is directed toward the second target detection area, which has been identified as the point where the chemical material is leaked among the first target detection area and the second target detection area;
• sensing external environmental information using an environmental information-collecting sensor;
• obtaining data about a chemical material on the second target detection area using the chemical material-detecting device;
• predicting a diffusion pattern of the chemical material based on the environmental information;
• detecting chemical material information based on the chemical material data;
• and
• providing a user alert based on at least one of the diffusion pattern of the chemical material and the chemical material information.
