Detailed description of the invention
For the technological means making the present invention realize, creation characteristic, reach purpose and be easy to understand with effect, below in conjunction with
It is specifically illustrating and the present invention is expanded on further.
With reference to Fig. 1, the induction door bell that sensitivity strengthens, including a Single Chip Microcomputer (SCM) system 1, also include vibrating sensor 4, vibration
Sensor 4 connects a signal input part of Single Chip Microcomputer (SCM) system 1；Single Chip Microcomputer (SCM) system 1 is additionally provided with a signal output part, and signal is defeated
Go out end and connect sonification system；Vibrating sensor 4 uses inertial pressure enhanced vibrating sensor, and inertial pressure enhanced is vibrated
Sensor includes a piezoelectric ceramic piece 11, and piezoelectric ceramic piece 11 includes metal substrate 9, and metal substrate 9 is provided with piezoelectricity pottery
Ceramic dielectric material layer, piezoelectric ceramics layer of dielectric material is coated with conductive electrode layer 12；Conductive electrode layer 12 is fixedly arranged above
One mass is more than 0.1g, the solid inertia load 13 less than 18g.Inertial pressure enhanced vibrating sensor have function admirable,
Cheap, thickness is thin the feature such as is easily installed.
By signal output part, output signal, such as acoustical signal, or control signal.Concrete it may be that sounding system
The signal output part of system communication wired connection Single Chip Microcomputer (SCM) system 1.
Also including a Shaking switch 6, Shaking switch 6 connects another signal input part of Single Chip Microcomputer (SCM) system 1.By rocking out
Close 6, the switch of door or rocking of door can be detected.And it is preferably and sound transducer is no longer set.The most no longer arrange
Electret sound transducer.
With reference to Fig. 5, also including a shell 7, and electric power system 2, electric power system 2 connects the feeder ear of Single Chip Microcomputer (SCM) system 1
Mouthful.Electric power system 2 is preferably battery case 77.It is preferably the battery case 77 of No. 7 batteries.Or preferably No. 5 batteries
Battery case 77.Electric power system 2 is preferably battery case 77.It is preferably the battery case 77 of two No. 7 batteries of joint.Or it is preferably
The battery case 77 of two No. 5 batteries of joint.
By above-mentioned design, it is allowed to gather vibration signal respectively by vibrating sensor 4, it is transferred to Single Chip Microcomputer (SCM) system 1, enters
And make Single Chip Microcomputer (SCM) system 1 possess the data basis accurately judging tap-tap, and then accurately judge.Allow judging there is tap-tap
Time, start sonification system and send doorbell voice prompt.
Whether Shaking switch 6, exist for perception door and rock, and when door exists and rocks, limits sonification system sounding.Men
After closedown, because being limited by doorframe and wall, it is clear that be difficult to produce and substantially rock.When door existence is substantially rocked, aobvious
It is so to exist to have opened wide, opening or closing.During these, all need not excite doorbell sounding.Cause
These situations, by the setting of Shaking switch 6, are shielded outside the situation exciting doorbell sounding, are substantially reduced software by this
Data analysis difficulty, and then reduce equipment cost, and reduce energy consumption.
Single Chip Microcomputer (SCM) system 1, after monitoring Shaking switch 6 triggering, limits sonification system more than sounding 3s.And limit sounding system
System below sounding 50s.More preferably, sonification system sounding 5s～20s is limited.Much further preferably from 4s～8s.Shake
The mode of dynamic switch 6 triggering can be, conducting, change in resistance or shutoff.
The mode limiting sonification system sounding is that Single Chip Microcomputer (SCM) system 1 no longer responds the useful signal of signal input part；Or be,
Single Chip Microcomputer (SCM) system 1 turns off the power supply of vibrating sensor 4 and connects；Or it is that Single Chip Microcomputer (SCM) system 1 software is adjusted to, even if
When being judged as having tap-tap, also locking signal output part, make sonification system not sounding.
Single Chip Microcomputer (SCM) system 1 is also connected with an anti-theft switch 5.Antitheft breakdown connection connects a signal input part of Single Chip Microcomputer (SCM) system 1,
When anti-theft switch 5 triggers, Single Chip Microcomputer (SCM) system 1 enters anti-theft modes.
Anti-theft modes is, triggers alarm at Shaking switch 6.When being in anti-theft modes, user should be door close.
When door is agreed to open without user, the induction door bell that sensitivity strengthens is arrived by the detection trigger of Shaking switch 6, Jin Ertong
Cross sound or other modes notify user.
This anti-theft modes, relative to burglary-resisting system based on tongue tube, have that structure is the simplest, it is more convenient to install,
Installation environment and the advantage such as installation site is freer.
Anti-theft switch 5 triggers, and after entering anti-theft modes, has more than 4 seconds time to be in restriction triggering state, triggers limiting
State, even if Shaking switch 6 triggers, does not reports to the police.So that the time of leaving allows user close the door.
The time being in restriction triggering state is preferably 10～30 seconds.To adapt to the living habit of people.Anti-theft switch 5 can be
One sensing soft-touch control, it is also possible to be a press button.Triggering anti-theft switch 5, when entering anti-theft modes, single-chip microcomputer system
System 1, excites generating device to send sound, or luminescent device is luminous.Activate with prompting user's anti-theft modes.At antitheft mould
Formula triggers anti-theft switch 5 again, releases anti-theft modes.Concrete software flow can be that Single Chip Microcomputer (SCM) system 1 is receiving
After the excitation signal of anti-theft switch 5, proceed to anti-theft modes, after entering anti-theft modes, have more than 4 seconds time to be in restriction
Triggering state, after restriction triggering state terminates, the triggering situation of monitoring Shaking switch 6.After Shaking switch 6 triggers,
Report to the police.The mode reported to the police can be by microphone device sounding alarm.Can also be to launch wireless communication by wireless system
Number report to the police.
In anti-theft modes, again trigger anti-theft switch 5 or other release antitheft switch, then release anti-theft modes.No
Report to the police again.
