Intelligent evacuation indicating system with positioning function and evacuation method

Abstract

The invention relates to an intelligent evacuation indicating system with the positioning function and an evacuation method. The system is composed of an escape RFID tag, positioning evacuation indicating nodes, an information processing transmission terminal and a monitoring display terminal. An implementing hardware platform is set up for acquiring position information, evacuation indicating node information and the like of trapped persons in the escaping process, a monitoring center can know the position information of trapped persons in a building in the escaping process in real time, the display direction of the evacuation indicating nodes can be comprehensively controlled according to the positions of persons, the fire source position and the like, the persons can be distributed and evacuated in assembly occupancies, and meanwhile, decision supporting is provided for rescue activities. The system integrates the evacuation indication function and the positioning function, and project cost is greatly saved. The system can also achieve remote control, meets the actual fire control requirement and is higher in practicability degree. The monitoring range can be adjusted by changing the wireless signal power. The system is more flexible to use.

Description

technical field [0001] The invention relates to the field of Internet of Things for building fire protection, in particular to an indoor positioning system based on an intelligent evacuation indicator lamp. It is suitable for buildings that must be equipped with a fire evacuation indicating system, and is used for positioning and evacuating people in the building during fire rescue. Background technique [0002] At present, our country is in a period of rapid economic and social development, various disaster-causing factors have increased significantly, and the scale of disasters has continued to expand, especially in high-rise, super high-rise buildings and other crowded places. Finding the escape route, quickly finding the safe exit, and launching the escape and self-rescue in time are the key to avoiding the tragedy. [0003] The intelligent evacuation indication system is a direction guidance system for personnel evacuation and evacuation, which is distributed and insta...

AI Technical Summary

Problems solved by technology

[0005] 1. It can only allow the trapped people to evacuate freely. When the visibility is very low, it is impossible to see or distinguish the indicated direction, which leads to the failure of the evacuation system.

[0006] 2. When a large number of people are evacuated, it is easy to cause casualties such as stampede, and the external control lacks the actual distribution of personnel as a reference, and the diversion command effect is not ideal

At present, most of the technologies that can realize indoor personnel positioning are based on the strength and transmission time of signal transmission. Theoretically, they have high positioning accuracy. However, in the actual implementation process, due to environmental factors such as occlusion, reflection, and temperature drift, Often the error is large, and the complex supporting facilities required also greatly increase the engineering cost of the system
