Description
Technical field
The utility model relates to padlock field, in particular to a kind of Internet of Things padlock and system based on LoRa technology.
Background technique
Lock, be owner be prevent other people open and the simple organ that sets, played in human civilization society and " take into custody beam
Tie up " function, standardize social action.Padlock is branch most ancient in lockset history, and being equipped on lock body can be with snapping
I.e. " lock bridge " cyclic annular or linear type shape metal stalk makes padlock directly become enclosed shape lockset with lock body snapping by lock bridge,
Make it have anti-theft function.
Existing padlock, after the spherical padlock of the seventies, the handle padlock of the eighties, to IC, RF electronic gate of the nineties
Lock improves safety and the practicability of traditional padlocks gradually to remote unlocking, portable, intelligent development, however such extension
Lock is generally basede on bluetooth, GPRS or NFC module, selects high band as signal of communication, carries out the remote authentication of legitimacy, although
It is inconvenient to carry to solve key, key is easy to the problems such as replicating, but its power consumption is high, generally requires frequent charge or replacement electricity
Pond influences the practicability of padlock.Secondly, being unlocked only with the certification of platform end by completing, it is easy to appear since user makes mistakes,
Remote authentication is successful and opens by mistake local lock, causes security risk.
Summary of the invention
Intelligent padlock power consumption is high in the prior art for above-mentioned, be easy to be staggered local lock the defects of, provide one kind and be based on
The Internet of Things padlock and padlock system of LoRa realizes remote unlocking, solves the problems, such as that intelligent padlock battery life is short, further mentions
The practicability of high padlock and safety.
To achieve the above object, the technical solution of the utility model is realized in.
Intracorporal master control borad, self-replaced type are being locked in a kind of Internet of Things padlock based on LoRa, including lock body, lock bridge and setting
Electromagnet, energy-storaging spring, limiting rivet, unlocking button.
It is provided with the first blind hole and the second blind hole on the lock body, the lock bridge includes the first lock pillar and the second lock pillar, and second
