Emergency evacuation methods and systems for smart city high-rise building fires based on an internet of things (iot) large model

An emergency evacuation method for smart city high-rise building fire based on an Internet of Things (IoT) large model, comprising:

• monitoring an environmental parameter of each of one or more geographic regions through a multimodal sensor group, wherein the multimodal sensor group includes at least one of a smoke sensor, a temperature sensor, and an oxygen sensor;
• identifying a fire risk region from the one or more geographic regions based on the environmental parameter and building information modeling (BIM) data through the processor;
• determining a first emergency kit and an evacuation route for evacuating from a building based on the fire risk region by retrieving the database, controlling the first emergency kit to automatically open an airtight door and release a first emergency robot, and sending an early warning notice to user terminals in the fire risk region and an adjacent geographic region;
• controlling the first emergency robot to move along the evacuation route via a wireless network and send a guidance signal to a user;
• in response to presence of a fire, identifying safety regions within the building from the one or more geographic regions through the processor, and sending the safety regions to a user terminal on a designated floor via the wireless network;
• determining a second emergency kit and a temporary evacuation route based on a distribution of the safety region, and controlling the second emergency kit to automatically open another airtight door and release a second emergency robot;
• and
• controlling the second emergency robot to move toward a nearest safety region along the temporary evacuation route via the wireless network, and sending the guidance signal to the user.

A non-transitory computer-readable storage medium, comprising computer instructions that, when read by a computer, direct the computer to execute an emergency evacuation method for smart city high-rise building fire based on an Internet of Things (IoT) large model, comprising:
