Losing suction can open the door, and existing electromagnetic lock is powered to silicon steel sheet always after closing, although power is relatively low, still can
Energy waste is caused, and silicon steel sheet can be caused to generate heat, influences service life.
There are a kind of electromagnetism lock control circuit, including power supply unit, electromagnetism lock unit, electromagnetic lock position detection currently on the market
Unit and automatic electric control unit, wherein electromagnetism lock unit have coil and Electromagnetic lock, the electromagnetic lock position detection unit
There is machinery association between electromagnetism lock unit, the location of when whether thus detecting Electromagnetic lock in work, and provides phase
The position detection signal answered；The automatic electric control unit is coupled with electromagnetic lock detection unit, in response to coming from electromagnetism lock position
The position detection signal of present position when the instruction Electromagnetic lock of detection unit is in work, by the electric current of the circuit where coil
From the first current switching to the second electric current, wherein the numerical value of the second electric current is less than the numerical value of the first electric current.The utility model provides
Electromagnetism lock control circuit, the problem of the problem of both having ensure that electromagnetic lock power output also solves self-heating, improve electromagnetism
The reliability of lock, but the control circuit carries out power supply switching by detecting the position of Electromagnetic lock, and be to be in when door body locking
Closed state, the control circuit can not solve the problems, such as energy waste when door body locking.
Invention content
The purpose of the utility model is to overcome deficiency in the prior art, provide a kind of anti-theft performance it is high, can be effective
It is energy saving, prevent electromagnetic lock generate heat intelligent cipher theftproof lock.
The utility model is achieved through the following technical solutions：A kind of intelligent cipher theftproof lock, including it is set to door body
On electromagnetic lock, door handle, door body lateral surface is additionally provided with Fingerprint Identification Unit, pressure sensing is additionally provided on the door handle

The controller is connect with electromagnetic lock, relay, Fingerprint Identification Unit, pressure sensor signal respectively, on doorframe with electromagnetic lock pair
It answers and is provided with iron plate at position.
Further, the door handle include grab handle, the extension bar that is connect with door body for grab handle, the pressure sensing
Device includes the foil gauge being set on extension bar.
Further, the power module includes transformer and regulator circuit.
Further, acoustic-optic alarm, the acoustic-optic alarm and controller signals are additionally provided in the door body
Connection.
Further, the controller is singlechip controller.
Further, the microswitch for detecting door body position, the fine motion are additionally provided between door body and doorframe
Switch is connect with controller signals.
The beneficial effects of the utility model are：Locking is carried out to door body by electromagnetic lock, can effectively avoid rotating
The possibility unlocked from outside is locked, security performance is high；Pressure sensor is set, when pressure sensor detects pressure change, electricity
Magnetic padlock is just started to work, can be effective energy saving, and electromagnetic lock is avoided to generate heat；Enabling personnel's body is identified by Fingerprint Identification Unit
Part, security performance is high；Microswitch is set, door opening action can be detected when personnel are not opened the door by handle, improves safety
Performance.
