S7, the feedback information that user is not received by the second setting time after triggering alarm, then cut off the user
Gas supply.After alarm triggering, user can send feedback information to system by specified operation, to release alarm.If
User, there is no reacting in time, illustrates that user may not receive warning message or can not lose after receiving alarm
Releasing alert capability.For example, in some cases, user sleeps very heavy, it is not known that alarms；Or user meets with promptly
Situation has lost consciousness.If gas leakage occurs in this case, consequence is hardly imaginable.Either above-mentioned which kind of
Situation should cut off the gas supply of the user to ensure the security of the lives and property of user.
In the present embodiment, it is 1 minute or 3 minutes that the second setting time, which can be set,.It is enough to allow user to possess
Time is confirmed, the gas supply that user is sudden shut off in user's just common gas is avoided.Certainly, user is if it find that urgent feelings
Condition can also disconnect steam line manually；User is the discovery that wrong report, can also open gas supply manually.
It is further comprising the steps of as preferred embodiment:
S8, notice of dying to the push of the mobile terminal of user.
The present embodiment needs to push notice of dying after user remotely dies to let the user know that the situation in family.
Otherwise, user may not just have gas supply in the state of ignorant suddenly in family.Notify user in time, it can be effective
Save gas company or time and the resource of user in ground.For example, gas pipeline by pet in family stings out one to user at night
Notch produces the flow less than small flow threshold, however user does not notice the warning message of mobile phone in one's sleep.System
System is since in the case where user does not feed back, system has cut off the gas supply of user by the gauge table of user.User second day
Get up, mobile phone has received notice of dying, which knows what situation has occurred, and voluntarily checks or contact in time combustion gas
Company's on-site maintenance.
As preferred embodiment, the third flow is regime flow, and the regime flow refers in third setting
Interior fluctuation is less than the flow of given threshold.
