8. a kind of Internet of Things lock method for unlocking with identity and password Intelligent key, it is characterised in that：Set in Intelligent key
Lock control circuit is set in key controller circuit, Internet of Things lock core, and the key billet of Intelligent key is conducting metal；
Its method for unlocking includes following execution step：
1.) Intelligent key is initially inserted into lock core, and the second electric contact of lock control circuit is contacted with key billet, key controller circuit
On single-chip microcomputer V2 output key insertion signal of the first electric contact short circuit into lock control circuit, single-chip microcomputer V2 detects the letter
Make to forbid unlocking apparatus to forbid lock core rotation unlocking by opening lock control circuit after number；
2.) after Intelligent key is fully-inserted, the first electric contact of key controller circuit and the second electric contact of lock control circuit connect
Touching makes two control circuit turn-ons；The power circuit of from single-chip microcomputer V2 power supply circuit to the crypto chip V1 are defeated in lock control circuit
Go out electric current to power to crypto chip V1, and the power source change of the power supply circuit provides clock arteries and veins to the crypto chip V1
Punching；
3.) the crypto chip V1 electrification resets, lock control circuit power supply circuit and clock control circuit output clock pulses are extremely
Key cipher chip V1 clock pins, afterwards crypto chip V1 send code data to single-chip microcomputer V2；
4.) single-chip microcomputer V2 is compared the crypto chip V1 of collection code data with the single-chip microcomputer V2 encrypted messages being pre-stored
Right, if comparison result is consistent, single-chip microcomputer V2 outputs allow unlocking signal to lock control circuit is opened, and unlocking control circuit output is just
To voltage to forbidding unlocking apparatus, it is allowed to which lock core is unlocked；If comparison result is inconsistent, single-chip microcomputer V2 is by opening lock control circuit
Control forbids unlocking apparatus to keep forbidding unlocking；
If 5.) above-mentioned comparison result is consistent, single-chip microcomputer sends key based identity information to network communication module；If comparison result differs
Cause, single-chip microcomputer V2 sends warning message to network communication module；Network communication module will receive information and send to the network platform；
Wherein during key insertion lock core, there is provided key unlocking letter for the second contact of key billet and lock control circuit
Number, single-chip microcomputer V2 sends control signal to unlocking control chip V3, unlocking control chip V3 is changed magnet coil L1 two ends
Polarity of voltage, control electromagnet DCT, which rises, to be forbidden unlocking；If data comparison is consistent, positive electricity is provided to magnet coil L1 two ends
Pressure, control electromagnet DCT declines, and departs from lock core, and the consistent legal key of tooth form can unlock.
9. method for unlocking according to claim 8, it is characterised in that：If the key cipher chip V1's of single-chip microcomputer V2 collections is close
Code data and the pre-stored encrypted message comparison results of single-chip microcomputer V2 are inconsistent, single-chip microcomputer V2 control warning circuit sound equipment warnings.
