Specific implementation mode
With reference to the accompanying drawings and examples, the specific implementation mode of the present invention is described in further detail.Implement below
Example is not limited to the scope of the present invention for illustrating the present invention.
As depicted in figs. 1 and 2, the multiple indoor warning devices of indoor smog alarm system provided by the invention, LPWAN (Low
Power Wide Area Network, low-power consumption WAN network) base station and remote alarming device, indoor warning device distribution
In floor or room, the base stations LPWAN and remote alarming device are distributed in control centre, and indoor warning device includes smoke sensing
Device, smoke sensing device include smog sensing module, power module and LPWAN modules；Electricity in each smoke sensing device
Source module is connect with its smog sensing module and LPWAN modules respectively, and smog sensing module is connect with LPWAN modules；LPWAN bases
It stands and is connect with remote alarming device；LPWAN modules in each smoke sensing device are connect with the base stations LPWAN；Each smog
In sensing device, power module is used to be smog sensing module and LPWAN module for power supply, and smog sensing module for acquiring in real time
Indoor smokescope data, and collected smokescope data are sent to LPWAN modules, by LPWAN modules by smog
Concentration data is sent to the base stations LPWAN；After the base stations LPWAN receive each collected smokescope data of smoke sensing device,
The collected smokescope data of each smoke sensing device are sent to remote alarming device, remote alarming device is according to each
The collected smokescope data of smoke sensing device judge whether fire occurs at the position where each smoke sensing device,
And when fire occurring at the position where remote alarming device determines any smoke sensing device, any smoke sensing is filled
The fire condition at position where setting is alarmed.
Wherein, control centre can be Fire Command Center, or need to find other platforms etc. of fire behavior in time.
Remote alarming device can be any terminal, such as mobile phone, computer or tablet, ensure that the remote alarming device can send out alarm
Signal.Remote alarming device may include loudspeaker and/or lamp, in alarm, remote alarming device can by whistle and/
Or the mode of flashing light is realized.In indoor smog alarm system provided in an embodiment of the present invention, in each room or floor
With one indoor warning device of arrangement, several rooms that can also be adjacent share an indoor warning device, i.e., indoor alarm dress
The quantity set can be set as needed.
In embodiments of the present invention, LoRa moulds may be used in the LPWAN modules in indoor warning device and the base stations LPWAN
Block (a kind of overlength distance wireless transport module based on spread spectrum).Smog sensing module in indoor warning device uses
MQ-2 gas sensors.Power module in indoor warning device can be accumulator, or alternating current, it can also be in alternating current
On the basis of be superimposed accumulator.It can be connected by USB interface between the base stations LPWAN and remote alarming device, at this point, will
After the base stations LPWAN are plugged on the USB interface of remote alarming device, remote alarming device can obtain each from the base stations LPWAN

The mobile terminal that iBeacon communication devices establish a connection inquires present position and/or report to remote alarming device
Fire condition at present position.
To sum up, which shares two communicating routes：The base stations LPWAN modules-LPWAN-remote alarms
Device and iBeacon communication devices-mobile terminal-remote alarming device.The former can reflect indoor smog concentration levels in time,
The latter supports user's active inquiry current location or alarm, keeps the indoor smog alarm system more secure, more hommization, more
It can prevent fortuitous event.When fire occurs, on the one hand, smoke sensing device detects fire and triggers remote control end
End alarm；On the other hand, indoor people is inquired or is alarmed by iBeacon communication devices and mobile terminal, so as to
Quickly determine fire behavior and convenient for quickly arranging rescue and fire extinguishing.
The positioning accuracy of traditional GPS (Global Positioning System, global positioning system) is about 10 meters of left sides
The right side, and the positioning accuracy of iBeacon communication devices can be from one meter to tens meter.Obviously, the positioning accuracy of iBeacon communication devices
It is better than GPS.GPS can orient an error wide range, for example can only judge user in some building, and the present invention is implemented
Example may determine which room of the user in building, positioning accuracy higher using iBeacon communication devices.In addition, this hair
Bright embodiment uses the iBeacon communication devices of low-power consumption, is located application of function in indoor smog alarm system, then can be with
In the case where fire visibility is very low, the position that user can be currently located by acquisition for mobile terminal, control device can be with
The position that trapped person accumulation regions are determined according to mobile terminal, to rescue more trapped persons, fire fighter as far as possible
Can by wear can be with the matched mobile terminal of iBeacon communication devices so that in the case where visibility is very low determine from
Oneself position, safely evacuates when the condition of a disaster is serious, ensures fireman's life safety.IBeacon communication devices are low power consuming
Bluetooth technology can effectively reduce the transmission power consumption between indoor warning device and remote alarming device to extend hardware components
Service life overhauls sensor compared to traditional timing, can reduce repairerment frequency.

Position be sent to mobile terminal, mobile terminal is according to the location determination where the iBeacon communication devices to establish a connection
Present position.
Wherein, it can also be previously stored between the mark and position of iBeacon communication devices in remote alarming device
Correspondence, therefore, remote alarming device are determined with movement eventually according to the mark of the iBeacon communication devices to establish a connection
When holding the position where the iBeacon communication devices that establish a connection, the pre-stored correspondence can be inquired, is obtained
Position where the iBeacon communication devices to establish a connection with mobile terminal.It is previously stored with iBeacon communication devices
It position can also be specific to room number.
If mobile terminal and a certain iBeacon communication devices establish connection relation, can determine mobile terminal with
The distance between the iBeacon communication devices are very close, may in a room, thus, will be moved in the embodiment of the present invention
Terminal present position is determined as establishing a connection the position where the iBeacon communication devices of relationship.
Pass through setting steps S4 to S6 so that when fire or other situations occurs, the user in room can pass through it
Mobile terminal positions the position being currently located.For example, when a fire, the user in room can allow control centre
Its current position is known, consequently facilitating the work that starts rescue.In another example fire fighter can also be by communicating with iBeacon
The matched mobile terminal of device determines the position of oneself in the case where visibility is very low, is safely evacuated when the condition of a disaster is serious, protects
Demonstrate,prove fireman's life safety.
Further, mobile terminal is current according to the location determination where the iBeacon communication devices to establish a connection
After position, mobile terminal can also obtain the fire condition at the position being currently located, and will be at present position
Fire condition be sent to remote alarming device.
Specifically, user can input the fire condition at the position being currently located in the terminal, when the current institute
After fire condition at position is sent to remote alarming device, fire behavior is grasped in time convenient for remote alarming device, and according to system
Fixed rescue plan, to reduce life and property loss when fire.
Above-mentioned all optionally technical solutions can be combined arbitrarily, and the present invention does not carry out the structure after combining one by one detailed
Explanation.
The above is only a preferred embodiment of the present invention, it is not intended to restrict the invention, it is noted that for this skill
