Fire-fighting and rescue survival means under ambient conditions have requirement higher and higher.In complicated fire-fighting and rescue process and environment,
Fire department usually needs to grasp the Temperature Distribution of scene of a fire each region in time, so as to correctly formulate fire-fighting and rescue party
Case, it is comprehensive to arrange fire-fighting resource, precisely effectively implement rescue, rescues people's lives and properties.Under such a scenario, how fastly
Speed accurately disposes temperature measuring equipment in scene of fire, and temperature distribution information is reliably sent out in real time, simultaneously for temperature
The precise positioning for spending test point physical location, becomes the primary key link of Rescue.
Although the application of temperature sensor has been mature technology, what kind of technical method and system are used, it is real
Existing thermometric, positioning quickly launch deployment and fire fighter or the person of requiring assistance are allowed to send emergency when lacking effective communication means
Information, becomes technical significant challenge, lacks existing technology platform at present and realizes this target.
The present invention provides one kind under the ambient conditions of the fire-fighting scene of a fire, and a large amount of fire scene temperature sensing devices of dynamic rapid deployment are simultaneously
The method and system of fire scene temperature distribution and physical location information is collected by LoRa communication apparatus.This system is by integrated temperature
The temp measuring system node apparatus of sensor and LoRa communication node and it is integrated with the gateway dress of LoRa gateway and background service control
It sets and is formed, the dynamic that temperature sensing node and Communication Gateway device can be carried out using unmanned plane is launched and disposed, and is suitble to
Application in the case of the building scene of a fire or other natural calamities and severe living environment, and can integrate based on NFC communications protocol
Man-machine interface, quickly and easily carry out personnel positions positioning and character message transmission, complete to cover feelings in missing communication network
Under condition, the thermometric in the fire-fighting scene of a fire, the Rescue process and method of positioning.
Summary of the invention
The technical issues of in order to solve proposed in background technique, the invention proposes one kind to be based on NFC and LoRa technology
Fire-fighting scene of a fire thermometric positioning system and method, using LoRa communication node (Node) module, and be mounted in unmanned plane or its
On his vehicle-mounted, convenient platform, LoRa gateway (Gateway) system of Dynamical Deployment constitutes dynamic LoRa private network or public network, adopts
The collection environmental informations such as lifesaving contact signal and associated temperature are simultaneously transmitted to background server, so that data are analyzed and are organized corresponding
Rescue action；LoRa node module has the function of temperature sensing and sends location information function, is integrated in small-sized soft outer casing mould
In block, it can throw or emit to the specific region in the scene of a fire in batch, carry out rescue and environmental data collecting；Meanwhile nobody
