When user gos out leaves behind electronic equipment, the electronic equipment that can be carried by user sends prompting message,
The electronic equipment that telling user has is not carried, such as the smart mobile phone, electron key, Intelligent bracelet same user is by indigo plant
Tooth connection setup is associated, and when user gos out, monitoring device has monitored the smart mobile phone information change for carrying, but does not monitor
There is synchronous change information to electron key, Intelligent bracelet, illustrate to have left behind electron key, Intelligent bracelet, monitoring device triggering
Application program in smart mobile phone, sends reminder message, tells that user's electron key, Intelligent bracelet are not carried.If carrying
Electron key, and forgotten smart mobile phone and Intelligent bracelet, can trigger the reminding unit in electron key, such as thumper,
Electromagnetic shaker etc., sends and the prompting message such as thunders or shake, and tells that user also has other electronic equipments not to be carried.
Further, open the door when user returns in the setting period, such as 10 after closing the door second, 30 seconds, door is opened again, prison
Device is surveyed according to electronic device information of going out just now, the association electronic equipment not being carried is waken up and is sent prompting message, or it is logical
Cross electronic equipment of going out and send wake-up information, wake up the association electronic equipment not being carried and send prompting message, such as by electricity
Thumper, electromagnetic shaker, LED lamplight in sub- equipment etc. send thunder, shake, the prompting message such as LED optical flare, guide user
Find.
The system includes intelligent door lock, and the electronic equipment includes Intelligent key, after Intelligent key is gone out, smart lock
Body authorizes Intelligent key of going out from outer unlocking authority, and when Intelligent key enters behind the door, cancellation enters Intelligent key from outer unlocking authority.
Further, the system includes networking unit, such as WIFI module, connection system to the webserver, monitoring device
Monitoring information is sent to server or smart mobile phone by network.
The present invention is to be generally in closed mode based on door, that is to say, that when user passes in and out, and is just opened the door, Ran Houguan
Close.
