Even if user is not in setting range, dangerous situation warning message can also be received the very first time, it is to avoid dangerous situation expands the economy brought
Loss or casualties.
The technical solution adopted by the present invention is：A kind of Intelligent indoor smog and flammable gas alarm based on APP, bag
Include：Smog and combustible gas sensor, microprocessor, wireless module, router, server and user terminal APP；The smog
And combustible gas sensor is connected with microprocessor, for gathering smog and fuel gas initial data, and by the cigarette collected
Mist and fuel gas initial data are sent after processing to microprocessor；The microprocessor is used to come from processing smog and flammable
The real time data of gas sensor, judges whether dangerous situation, if then exporting warning message；The wireless module and microprocessor
Device is connected, and warning message is sent into server by router；The router and wireless module wireless connection；The service
Device and router wireless connection；The server is used to receive warning message, and warning message is transmitted into user terminal APP.
Further, in addition to：Buzzer and LED alarm lamp；The buzzer is connected with microprocessor, in microprocessor
Control under, beep alarm；The LED alarm lamp is connected with microprocessor, and bright light is put under control of the microprocessor
Light carries out light warning.
Further, the alarm also includes：Amplifying circuit and A/D converter circuit；The amplifying circuit to smog and
The initial data that combustible gas sensor is collected is amplified processing；The data that the A/D converter circuit exports amplifying circuit
It is converted into the recognizable data of microprocessor.
Beneficial effects of the present invention：A kind of the Intelligent indoor smog and flammable gas alarm based on APP of the present invention, leads to
Addition wireless module is crossed, when there is dangerous situation, is transmitted warning message to server by wireless module, server alarms this
Information is forwarded to user terminal APP, and time limit remote alarms can cause dangerous situation to be handled in time, is prevented effectively from loss and expands；This
The alarm of application has advantages below：
(1) there is advanced and practicality, using Internet of Things correlation technique, facilitate equipment to access internet.User is provided
Mobile phone app is so as to more timely obtain warning information；
(2) there is stronger applicability, indoor scene, such as family kitchen, industrial premises, storehouse can be applied to wide
Storehouse, gas station etc. are likely to occur the scene of fire；
(3) there is very strong real-time, when combustable gas concentration is higher or when there are a large amount of smog generation dangerous situations, use
Family end app can receive warning message immediately.

Fig. 2 is smog of the present invention and flammable gas alarm software system framework figure.
Embodiment
For ease of skilled artisan understands that the technology contents of the present invention, enter one to present invention below in conjunction with the accompanying drawings
Step explaination.
As shown in figure 1, the technical scheme is that：A kind of Intelligent indoor smog and combustible gas alarm based on APP
Device, including：Smog and combustible gas sensor, microprocessor, wireless module, router, server and user terminal APP；
The smog and combustible gas sensor are connected with microprocessor, for controlling Smoke Sensor to monitor smog in real time
And fuel gas and analog signal is produced, transfer to analog-digital converter to be converted into the data signal that can be recognized to miniature processing afterwards
Device.
The alarm also includes：Amplifying circuit and A/D converter circuit；What smog and combustible gas sensor were collected
Data are converted into the recognizable data of microprocessor by initial data via amplifying circuit and AD converter.
The microprocessor is used for the real time data from processing smog and combustible gas sensor, judges whether danger
Feelings, if then exporting warning message；And control buzzer and red LED indicator lamp to send alarm.
The wireless module is connected with microprocessor, is under control of the microprocessor transmitted warning message by router
To server.
The router and wireless module wireless connection；The server and router wireless connection；The server is used
In reception warning message, and warning message is transmitted to user terminal APP.User terminal app：Alarm signal is received, message is sent
Notify, alarmed to user.
In the present embodiment, the smog and combustible gas sensor use MQ-2 sensors.The model sensor is made
Gas sensitive is the relatively low tin ash of electrical conductivity (SnO2) in clean air, and sensor is to liquefied gas, propane, hydrogen
Sensitivity it is high, the detection to natural gas and other combustible vapors is also highly desirable.This sensor can detect a variety of flammable gas
Body.
The microprocessor use TI companies the chips of CC 3200, built-in high-performance ARM Cortex-M4MCU, and comprising
