Description
Technical field
The present invention is a kind of intelligent door lock system based on narrowband technology of Internet of things, belongs to intelligent door lock control technology neck
Domain.
Background technology
The municipal administration for various purposes of many of city, communication babinet, how to manage these babinets is put in city manager
A difficult problem in front.Construction personnel must carry mechanical key opening babinet to site operation and construct at present, but use
Mechanical key has many defects, and first, key management difficulty is lost the phenomenon that damaging and occurred often, once it can be used without key inevitable
Influence construction efficiency；Secondly, construction personnel forgets band key or tape error key after often arriving scene, in this case construction personnel
It goes back that or key violence is taken to open chamber door, no matter which kind of situation will all bring deleterious effect；Again, it can not realize remote
The tracking of Cheng Kaisuo and record of unlocking；Finally, can not be in real time to the real time monitoring of chamber door and lockset, some municipal cabinet doors are long-term
Month after month in opening state, exposing to the sun and rain causes internal unit damage to cause very big economic loss, if case can be found in time
Body door is not turned off then can be to avoid this loss.
And the existing common power supply mode of Cabinet intelligent door lock has：In door body placing battery, pass through electronics key
Spoon externally fed or connection power cord, these door lock generally use bluetooth keys communicate with mobile communication or by rotating ring system
Mode realize to data report and the management of door lock, these modes are there are several shortcomings, first using electron key
Unlocking mode need to by mobile phone could synchrodata, can not upload door lock and door body in time in the case where no mobile phone participates in
Real-time status, can not monitoring management especially to illegally opening the door；Secondly, internal battery uses other communication modes（Such as GPRS）
Scheme can not achieve low-power consumption, and signal is influenced to have attenuation by babinet material, in turn results in unlocking low-response not even
Success also adds the operation and maintenance cost of battery；And the electronic lock for connecting rotating ring system is frequently used in active door body, and
And cabinet domestic demand has expensive rotating ring system, passive cabinet can not use.
For existing passive intelligent cabinet lock due to being unable to real-time interconnection, can not equally realize to the real-time of cabinet door and lockset
Monitoring, and this lockset need to be equipped with a special active unlocking apparatus（Electron key）, this device exists simultaneously loss
The risk of damage.
Based on cellular narrowband Internet of Things（Narrow Band Internet of Things, NB-IoT）As Internet of Things
One important branch of net.NB-IoT is a low-power consumption wide area network, is implemented in cellular network, only consumes the band of about 180KHz
Width can be deployed directly into GSM network, UMTS network or LTE network.Super low-power consumption overlength can be realized by accessing the terminal at this network
It is standby, network can be accessed rapidly when there is event triggering and upload event information to server.
Invention content
Proposed by the present invention is a kind of intelligent door lock system based on narrowband technology of Internet of things, existing its object is to solve
Mechanical key must be carried when unlocking present in technology, battery need to be often replaced using Intelligent key, cabinet can not be monitored in real time
Door, lockset and battery status, and the problem of use cost is higher provide a kind of low-power consumption, high real-time and reliable and stable
NB-IoT intelligent door lock systems, realize unlocked by mobile phone scene or long-distance remote control unlock and to cabinet door, lockset and
The real time monitoring of battery status.
