Indoor emergency response and context awareness navigation system and method

Abstract

The invention relates to an indoor emergency response and context awareness navigation system and method. The navigation system at least comprises a location sensor network, a server and an early warning sensor, wherein the location sensor network comprises a location base station, a mobile terminal and / or a location label and an LED (Light Emitting Diode) screen; the location base station is in wired or wireless connection with the server; the mobile terminal and / or the location label is in wireless connection with the location base station; the LED screen is in wired connection with the location base station; the early warning sensor is in wireless connection with the server. The navigation method is capable of combining a plurality of context calculation navigation paths of indoor environment, self-adaptively presenting the navigation paths to users according to the scenes of the users in many ways and providing real-time, accurate and individual navigation service. The navigation system and the navigation method are applicable to personnel location, emergency evacuation, rescue after disaster and safety management of large complex indoor venues such as hospitals, markets, office buildings and stations; meanwhile, the navigation system and the navigation method are capable of improving scientificity, timeliness, effectiveness of emergency response of public places.

Description

technical field [0001] The invention relates to an indoor positioning and navigation system, which belongs to the field of indoor positioning and navigation and location services, and in particular to an indoor emergency response situation awareness navigation system and navigation method. Background technique [0002] With the rapid development of technologies such as geographic information system (GIS), location-based services (LBS) and the Internet of Things, spatial information technology and applications have gradually expanded to indoor spaces. It is estimated that 80% of the information that people obtain is related to location, and people spend as much as 87% of their time in indoor spaces every day on average. People's demand for indoor location information is becoming more and more urgent. In particular, hospitals, shopping malls, office buildings, stations and other large indoor places have complex environments and highly concentrated personnel. In an emergency, h...

Problems solved by technology

[0004] However, the indoor navigation systems in the prior art are usually not equipped with fire alarm sensors or smoke sensors, so in the event of fire or toxic gas diffusion, it is impossible to provide a safe and effective escape route

At the same time, there are many influencing factors in the actual indoor environment, such as the moving speed of different types of people, road types, road safety, fire protection facilities, lighting conditions, etc., which play a key role in realizing efficient real-time evacuation navigation and auxiliary decision-making services. However, there is currently no indoor navigation system that takes these influencing factors as input data.

In addition, different types of users such as ordinary people and disabled people have quite different navigation needs, and the existing indoor navigation systems usually only provide two or three maps or voice navigation methods, and cannot provide navigation paths and guide information suitable for different groups of people. Unable to meet the user's personalized navigation service needs
