Abstract
The invention discloses a contactless electromechanical password lock based on a Hall sensor. The contactless electromechanical password lock comprises a microcontroller, a Hall sensor, a voice prompt circuit, a mechanical lock driving module and a mechanical lock. The microcontroller is connected with a Hall sensor module, a mechanical lock driving module, a voice prompt module and a CAN (control area network) bus interface unit, and used for system control; the Hall sensor module is used for magnetically responding and transmitting an induced signal to the microcontroller; the voice prompt module is used for voice prompt in the unlocking process; the CAN bus interface unit is used for transmitting unlocking information to a host computer by employing a CAN bus; and the mechanical lock driving module is used for driving the mechanical lock.
Description
Technical field
The present invention relates to a kind of coded lock, be specifically related to a kind of contactless Electromechanicla puzzle lock based on Hall element.
Background technology
Coded lock has been along with the progress of science and technology has obtained very big development, electrical type coded lock especially, and the form of mechanical code lock is then dull relatively, and generally the angle through rotational lock core is provided with password and unlatching.Then occurred like high-tech coded locks such as Fingerprint Lock, iris locks in the electronic type coded lock, though the confidentiality of these coded locks has been mentioned raising, stability is not fine, is easy to receive external condition to influence.And these coded locks all have a general character; Be exactly all to be contact or type contact; Being that the opener can see locking device intuitively, in time is that this kind contact coded lock of iris lock exists same problem too, if violence damage then coded lock disabler.
The coded lock of general present appearance all can't prevent violence damage, if a kind of non-contact type is arranged, the person that promptly do not unblank can't directly touch unlocking apparatus, has so just effectively prevented violence damage.And present coded lock generally do not have real-time monitoring and control, is disadvantageous for some places of extremely maintaining secrecy like this.
Summary of the invention
In order to address the above problem; The invention provides a kind of contactless Electromechanicla puzzle lock based on Hall element, this coded lock that utilizes Hall switch sensor to carry out release, the person of unblanking can only see the lockhole that array is arranged; Through adopting special magnetic key; Press decoding process near contact opening, then internal sensor induction back is opened lock by the microprocessor controls coding lock system.So just realized that non-contact type unblanks, and effectively prevented external violence damage.And this unlocking system provides real time monitoring function, and promptly real-time is sent to main frame with the information of unblanking.
The technical scheme that the present invention adopts is: a kind of contactless Electromechanicla puzzle lock based on Hall element comprises that microcontroller, Hall element, voice warning circuit, mechanical lock drive and mechanical lock.
Said microcontroller and Hall element module, mechanical lock driver module and voice cue module and CAN Bus Interface Unit are used for system's control;
Said Hall element module is used for magnetic response and induced signal is sent to being controller; Said voice cue module, the process voice suggestion is used to unblank;
Said CAN Bus Interface Unit is used to utilize the CAN bus that the information of unblanking is sent to main frame;
Said mechanical lock driver module is used for the driving device lock;
First preferred version of the present invention is that said Hall element is a Hall switch sensor.
Second preferred version of the present invention is that said Hall element is that array is arranged.
The 3rd preferred version of the present invention is also to comprise the interface expanding element, between said interface expanding element connection microcontroller and the Hall element.
The 4th preferred version of the present invention is that said microcontroller adopts the MSP430 single-chip microcomputer.
The 5th preferred version of the present invention is that said voice cue module adopts the IS4004 speech chip.
Technical advantage of the present invention is: adopt based on Hall switch sensor, reached the coded lock non-contact type and opened, prevented external violence damage, and real-time system monitoring function is provided, make security performance improve greatly.
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is further specified.
Description of drawings
Fig. 1 is an embodiment overall structure sketch map.
Fig. 2 is an embodiment extended interface unit sketch map.
The specific embodiment
With reference to shown in Figure 1.Microcontroller adopts the MSP430 single-chip microcomputer;, Hall switch sensor sends induced signal to microcontroller when sensing magnetic; The microcontroller detection signal is also unblanked; System is provided with the trigger end of unblanking, and the person that at first do not unblank should trigger this sensor with magnetic key, just can carry out unlock operation then.In the process of unblanking, have voice suggestion, when mistake occurring in the double process of unblanking, system will automatically lock this moment, can't unblank again.
Microcontroller is connected with the CAN EBI, and real-time the information of unblanking is sent to main frame, and main frame will write down all information of unblanking like this.Need pass through the host setting unlocking cipher when initial, simultaneity factor provides user ID coding, and when release all has record for whom like this, has strengthened the management of password, and the place for high security requirements is very necessary like this.If system's entering automatically locks state then must have main frame to open.
With reference to shown in Figure 2.Extended interface unit adopts 8255A as the I extended chip; Bus end links to each other with microcontroller; Expansion IO mouth is connected with Hall element, and when the magnetic key release, Hall element sends induced signal to 8255A and then read by microcontroller.Native system adopts two IO extended chips, has satisfied the requirement of Hall element docking port quantity in the system.
