Description

A kind of Internet of Things padlock and padlock system based on LoRa
Technical field
The present invention relates to padlock field, more particularly to a kind of Internet of Things padlock and system based on LoRa technologies.
Background technology
Lock is owner to prevent that other people open the simple organ set, is played in human civilization society and " takes into custody beam Tie up " function, specification social action.Padlock, is branch most ancient in lockset history, equipped with can be with snapping on lock body Cyclic annular or linear type shape metal stalk, i.e., " lock bridge ", so that padlock is passed through lock bridge directly becomes enclosed shape lockset with lock body snapping, Make it have anti-theft feature.
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, the problems such as key is easy to replicate, but its power consumption is high, generally requires frequent charge or replaces electricity Pond influences the practicability of padlock.Secondly, it is unlocked, is susceptible to since user slips up by completing only with the certification of platform end, Remote authentication is successful and opens by mistake local lock, causes security risk.
Invention content
In for the above-mentioned prior art, intelligent padlock power consumption is high, is easy the local the defects of locking that is staggered, provides 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 carries The practicability of high padlock and safety.
To achieve the above object, the technical proposal of the invention is realized in this way.
A kind of Internet of Things padlock based on LoRa, including lock body, lock bridge and the master control borad being arranged in lock body, self-replaced type 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 A trapezoidal lock tongue card slot is opened up on lock pillar.
The self-replaced type electromagnet includes induction coil, armature, lock tongue and resetting spring, the armature free end and lock Tongue connects, and when self-replaced type electromagnet is powered, armature bounces back under magneticaction with lock tongue, trapezoidal lock tongue card slot and lock tongue It threads off, unlocks successfully, further second blind hole coordinates with limiting rivet, ensures that the second lock pillar is in the second blind hole after unlocking In can rotate by a certain angle and cannot screw out;When the self-replaced type electromagnet power-off, armature is under resetting spring thrust Drive lock tongue to be pushed forward, trapezoidal lock tongue card slot and lock tongue cooperatively form lock, lock successfully, further, the first blind hole to The first lock pillar of limitation lock bridge screws out after padlock locking.
The energy-storaging spring be arranged the second blind via bottom, lock bridge the second lock pillar below, user unlock when, press down on Lock bridge flicks lock bridge after the energy-storaging spring accumulation of energy.
The first blind via bottom in lock body is arranged in the unlocking button, and user presses down on lock bridge when unlocking, drive first Lock pillar triggers unlocking button and wakes up master control borad after the triggering of unlocking button.
The master control borad includes MCU, communication module, spring antenna, output circuit, power supply module, mini USB interface, institute It states MCU to be responsible for inquiring the validity for order of unlocking to server, and unlocking instruction is sent to self-replaced type electromagnet;The communication Module uses LoRa communication modules, is connect with the MCU, the inquiry instruction of the MCU is converted to and is transmitted wire-lessly to take Business device, and the unlocking instruction that server issues is fed back into the MCU;The spring antenna connects with the LoRa communication modules It connects, is built in lock body;The output circuit is connect with the MCU universaling I/O ports, after MCU sends out unlocking instruction, output electricity Road drives the of short duration energization of self-replaced type electromagnet;The power supply module includes lithium battery, to give the master control borad to power; The mini USB interface is connect with the power supply module and the MCU, is lithium battery charging and system maintenance liter in power supply module The external interface of grade.
A kind of padlock system of the Internet of Things padlock based on LoRa using above-mentioned, including the LoRa Internet of Things padlock, LoRa gateways, server, user terminal.
When unlocking, user is based on user terminal, sends to unlock to server and asks and duration T, server is authorized to receive institute User's unlocking authority is verified after stating the unlocking request of user terminal, if Authority Verification fails, padlock matching is issued to user terminal Failure command;If Authority Verification passes through, server is by this request of unlocking of user terminal as LoRa Internet of Things padlocks Key stores, if authorizing the key matching request for not receiving LoRa Internet of Things padlocks in duration T seconds, abandons the key simultaneously Padlock is issued it fails to match instruction to user terminal, if authorizing the key for receiving LoRa Internet of Things padlocks in duration T second to match Request and the two successful match then issue the instruction of padlock successful match simultaneously to user terminal and LoRa Internet of Things padlock.
After user is based on user terminal submission unlocking request, user is locally pressing downwards the LoRa Internet of Things padlock Lock bridge drives the first lock pillar to trigger unlocking button, after the triggering of unlocking button, wakes up master control borad, the MCU of master control borad is by communicating mould Block sends key matching request by LoRa gateways to server, if receiving padlock it fails to match instruction, the MCU is without opening Lock operates and enters dormant state;If receiving the instruction of padlock successful match, the MCU drives Self-resetting by output circuit Formula electromagnet energization 200ms, armature bounce back under magneticaction with lock tongue, and the lock tongue card slot on the second lock pillar is de- with lock tongue Button, unlocks successfully, and the lock bridge pops up under energy-storaging spring effect.
It is powered off after the self-replaced type electromagnet energization 200ms, the master control borad enters dormant state, the self-replaced type Electromagnet armature drives lock tongue to be pushed forward under resetting spring thrust, and user pushes lock bridge, and lock tongue is again introduced into trapezoidal lock Tongue card slot forms lock, locks successfully.
Internet of Things padlock and padlock system provided by the invention based on LoRa technologies, networking is convenient, is wirelessly transferred, and increases Unlocking button, only remote unlocking ask to unlock with the local unlocking button successful match that triggers, prevent long-range maloperation and It opens by mistake local lock and causes security risk.Simultaneously unlock button be used as wake-up switch, if matching it is unsuccessful quickly enter suspend mode, as With success, enter suspend mode after driving Self-resetting electromagnet energization 200ms by output circuit, from wake up to unlock successfully after again Dormancy time is no more than 1s, meets super long standby time demand.
