System and method.
Background technology
The application of Domestic gas warning system history the most for many years.Gas alarm in early days
System uses and uses sound and light alarm more, and being merely capable of solution has alarm-free problem.
Along with popularizing of intelligent home device, especially support that the equipment of Zigbee protocol obtains
After commonly used, the intelligent level of home-use gas alarm system gets a promotion.
Such as, CN103578233A discloses a kind of home-use note gas alarm system and report thereof
Alarm method, its function includes, when the gas concentration detected exceedes certain value, using micro-
Processor generates the note containing warning message, by note discharger by short message sending
To handheld terminal such as mobile phone.The most such as, CN103065438A discloses a kind of combustion gas report
Alert device, can cut off gas supply in time when there is the condition of a fire or similar dangerous situation.
But, the gas alarm system of Smart Home of the prior art, still can only expire
Sufficient basic alarm notification and cutting function.Intelligent treatment cannot be carried out as the case may be.
Such as, in the case of there is micro-leakage because gas-cooker surprisingly extinguishes in combustion gas, as
The on-the-spot Attended mode of fruit, disposal options only needs to turn off burnt gas valve even gas-cooker,
Without notifying fire-fighting and gas rush-repair department, more visit without first-aid personnel.And when scene
During unmanned, or when indoor occupant loses ability to act, need requirement property, combustion
The process of visiting rapidly such as gas company even first-aid personnel.

Block 136 and 144 may also comprise light sensor, and gravity sensor etc. can detect that environment
The sensor of change.When mobile terminal 103 and wearable device 104 are receiving alarm signal
After number, as produced activity sensor signal M_ACT or W_ACT, then activity aware is believed
Number return to gateway 102.In gateway 102 priming chamber after alarm mode second
In time interval T2, as do not received from wearable device 104 and mobile terminal 103
Activity sensor signal, does not receives the user instruction from described mobile terminal 103, then yet
Presumption user may be not in indoor or be in indoor but do not obtain warning message, net
Close 102 and transfer alarm mode to outdoor alarm mode from indoor alarm mode.
In the another alternative embodiment of above-described embodiment, report in gateway 102 priming chamber
In the 3rd time T3 after alert pattern, receive described wearing perceptual signal W_DEC but not
Receive activity sensor signal W_ACT, and from alarm signal G_ALA of fuel gas alarm
When the combustion gas that prompting detects is poisonous combustion gas, then presumption indoor occupant has been poisoned, nothing
Power is disposed dangerous situation and also may be in peril of one's life, gateway 102 will by communication module 121 to
Fire-fighting and medical first aid department report to the police.
The current problems faced of wearable device is due to battery limitation, it is impossible to persistence work
Make.When wearable device electricity depleted shutdown, it is impossible to play its due warning function.
