Control processor, when smokescope numerical value is set less than in control processor greater than minimum numerical value set in control processor
When the highest numerical value set, the information that slight fire occurs is wirelessly transmitted to resident's mobile phone 5 and residential property fire by control processor
Calamity alarm 9, resident's mobile phone 5 can be plurality of mobile phones, and when nobody home at this time, resident can confirm to property at the first time
A situation arises for fire, while property or skilled staff can enter the help fire extinguishing of resident family, when firefighter reaches resident's door
When mouth, resident passes through resident's mobile phone 5 again and controls control processor opening camera 2, confirms that doorway is when checking by camera 2
After firefighter, then control processor is controlled by resident's mobile phone 5 and opens electronic lock module 6, firefighter can enter room
Interior fire extinguishing reduces stranger and enters and do not put out a fire the case where only stealing indoor property generation, and during this, 2 pairs of camera enter people
Member records a video, and Video content is reached cloud processor 14 by control processor and is stored, and resident's mobile phone 5 can be from cloud
It extracts Video content in processor 14 to be checked, when resident is at this time, since the intensity of a fire is smaller, resident and property etc. can be with
Common fire extinguishing, does not take the measure directly alarmed to fire alarm 10, reduces the waste of fire-fighting police strength, when generation severe
When fire, i.e., when the smokescope numerical value that Smoke Detection probe 13 detects is greater than highest numerical value set in control processor
When, control processor automatically controls electronic lock module 6 and opens, while to resident's mobile phone 5, residential property fire-alarm 9 and disappearing
Fireproof alarm 10 is alarmed, and is omitted the step of manually alarming to fire alarm 10, is controlled in time the intensity of a fire, this
When firefighter can be directly entered interior and put out a fire, may be implemented both to can be reduced the safety when fire occurs for nobody home
Door 7 closes the case where firefighter cannot be introduced into indoor fire extinguishing generation, and can be simultaneously to multi-section resident mobile phone 5 and residential property
The generation of the prompting fire of fire-alarm 9, moreover it is possible to when fire is serious, alarm in time to fire alarm 10.
The preferable specific embodiment of the above, only the utility model；But the protection scope of the utility model is not
It is confined to this.Anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this
Novel technical solution and its improvement design is subject to equivalent substitution or change, should all cover in the protection scope of the utility model
It is interior.
