The intelligent visual Internet of Things technology integrates the ubiquitous cameras in the urban surveillance area into the intelligent visual Internet of Things, obtains visual information through visual sensors, visually labels people, vehicles, objects, and environments, and mines target trajectories and environmental changes. Analyze its behavior and provide early warning information for the emergency command system.
The core of the construction of the city's emergency command system is the goal of “disposal of ordinary events, coordinated command of major events, and vertical and horizontal grid three-dimensional linkage”. The emergency command system consists of two major systems. One is the emergency command system for daily emergency response and the other is a strategic system for coordination command and decision analysis of emergency command.
Urban "4+1" Emergency Command System
The emergency command system constructed by Belleson can be summarized as one sentence: "based on VIDC, to achieve intelligent perception, interconnection, coordination, sharing and urban operations," referred to as "emergency command 4 +1 system." Among them, 4 subsystems are: intelligent vision-based Internet of Things technology for real-time intelligent perception of people, vehicles, things, and roads; city information is interconnected and interoperable through three networks; city information resources are collaboratively shared among officials, businesses, and citizens; intelligent City level alarm operation.
IntelliSense

City operations
Function: The role of the emergency command system in city operations in peacetime is to provide emergency response to emergencies. The state establishes a regional emergency rescue organization for accidents and undertakes emergency rescue work for special major accidents. According to the requests of the people's governments of provinces, autonomous regions, and municipalities directly under the Central Government, regional emergency rescue organizations for accidents shall assist local people's governments in carrying out emergency rescue work for safety accidents. The on-site emergency rescue command organization follows the principle of territoriality-based and combination of blocks. The local government is responsible. According to the response level of the accident, the local emergency response headquarters shall be composed of corresponding local governments or professional emergency command agencies. The person-in-charge or the person in charge of the professional emergency commanding organization serves as the general commander to direct and coordinate the emergency rescue operations.
