The system has collected over 3,000 types of MSDS and more than 2,000 global hazardous chemical accident cases. Based on the Gretter G-SES® cloud platform, by leveraging technologies such as industrial Internet of Things, artificial intelligence, virtual reality, digital twin, mobile internet +, big data cloud computing platform, etc., it has connected over sevral tens safety emergency subsystems, including automatic fire alarm, video surveillance, public address intercom, access control, perimeter intrusion detection, pipeline infrasound leakage monitoring, cathodic protection monitoring, unmanned aerial vehicle collaborative operations, etc. Through multi-dimensional sensor fusion, AI video intelligent recognition, emergency communication integration, fire alarm video linkage, fire intelligence analysis, digitalized emergency response plan functions, it has achieved wide-area fire monitoring, multi-scenario multi-level hierarchical warning, AI intelligent alarm reception, precise equipment linkage, emergency rescue force dispatch and command, 3D visualization of safety monitoring and warning, traceable safety hazard inspections, full-process management of safety hazards, and data sharing with SIS, SCAD, DCS, MES, LIMS. It has solved problems such as difficulty in grasping real fire alarms, outdated analysis methods, low efficiency of fire rescue command and dispatch, inability to implement responsibility entities, lack of safety risk assessment, insufficient fire public service capabilities. It has characteristics of "automatic" fire prevention and control, "intelligent" fire rescue command, "systematized" daily law enforcement work, "refined" team management.
