The specific embodiment
The CN201794392U that is related applicant in view of this case further improves, this case does not understand that part refers to CN201794392U, this case essential structure as depicted in figs. 1 and 2, to its basic structure,, by CN201794392U is clearly stated, do not repeat them here.
About its basic structure, as Fig. 1 and Fig. 2, referring to the CN201794392U quoting, the structure that has direct correlation in this case is related without battery powered electric lockset, comprise tapered end 1 and key 2 that the use electronics mode that matches is unblanked, wherein tapered end 1 comprises and with lock core base hole, forms the lock body of stator 3 and coordinate with lock core base hole and form the lock core of rotor 4;
Wherein, the position that stator 3 mates lock core base hole is provided with stator coil, and is provided with the super capacitor that is connected in described stator coil in tapered end, and the CPU take this super capacitor as power supply;
Key 2 comprises the capacitor that connects described super capacitor by charging circuit, and this capacitor is as the power supply of key;
Than CN201794392U, described charging circuit is provided with the first relay driving into a described CPU, this first relay passes through context-aware, for the part that connects charging circuit in other words operating part contain normally open contact, correspondingly, described electric lockset also comprises that the described super capacitor of connection is to carry out the voltage sampling apparatus of voltage sample, this voltage sampling apparatus output is connected in a described CPU, to drive the first relay at institute's sampled voltage in setting range, and capacitor is charged;
And a described CPU is also connected with charge switch, to carry out the whether judgement in setting range of institute's sampled voltage the switching value of this charge switch input in the situation that.
According to foregoing, it has increased by two pass points, the voltage between the pole plate that pass point is super capacitor (Supercapacitors), by and connect super capacitor and can carry out the sampling of relevant voltage.
Super capacitor has another name called electrochemical capacitor (Electrochemical Capacitors), double layer capacitor (Electrical Doule-Layer Capacitor), gold electric capacity, farad capacitor are to carry out a kind of electrochemical element of energy storage from the polarization electrolyte that passes through that grow up the 1970s and 1980s in last century.
It is different from traditional electrochmical power source, be a kind of between traditional capacitor and battery, there is the power supply of property, mainly rely on electric double layer and redox pseudocapacity charge storage electric energy.But there is not chemical reaction in the process in its energy storage, this thermal energy storage process is reversible, just because of can repeated charge hundreds thousand of times of this ultracapacitor yet.The double layer capacitor of its basic principle and other kind is the same, is all to utilize the double electrical layers of active carbon porous electrode and electrolyte ingredient to obtain the capacity of super large.
Outstanding advantages is that power density is high, the time that discharges and recharges is short, have extended cycle life, operating temperature range is wide, is the one that has dropped in the world capacity maximum in the double layer capacitor of volume production.
Because power density is high, can hold larger electric weight, the voltage range that makes it to set while making it as pass point is larger, and still has greatly higher encryption to be worth in the scope nargin allowing.
For avoiding continuous trial, need to limit voltage sample, in the time of boost voltage sampling, form again another pass point, the on-off times that switching value is sent.
First be auxiliary, when touch switch, the voltage of sampling just can be judged, and first pass point just can carry out in other words, when the number of times of second pass point is restrained, and the execution that voltage sample just can not be too much.
When those skilled in the art just can carry out in the scope as being no longer scheduled at institute's sampled voltage so, just can not carry out the checking of key legitimacy.
If attempt unblanking, inevitably to carry out the repeatedly charging to super capacitor, with this understanding, can carry out thresholding control and avoid super capacitor to overcharge.Also can avoid legal the produced super capacitor of normally unblanking to overcharge.
About the electric discharge of super capacitor, one is nature electric discharge, and the natural velocity of discharge is very slow, to the trial of above-mentioned two pass points, can not a condition be obviously basis.Therefore, preferably adopt artificial physics electric discharge, to this, described super capacitor is also connected to discharge circuit, by super capacitor is discharged.
As shown in Figure 3, described discharge circuit comprises a protective resistance R and the button SB that is serially connected with this protective resistance, and protective resistance R is mainly protection super capacitor, avoids heavy current impact.
In discharge circuit, can also add an inductance, R is connected in series with protective resistance, can further protect super capacitor.
About counting, can directly use a CPU to count, current CPU is furnished with high-speed counting port mostly, can directly be used for counting, and also can carry out soft counting, according to sampling number, counts, and also can count according to charge switch.
In some preferred embodiments, described voltage sampling apparatus is also connected with zero clearing counter, and to add one at institute's sampled voltage as 1 o'clock, this zero clearing counter output connects a described CPU;
Correspondingly, described charging circuit also comprises the second relay that is serially connected with the first relay, and the drive end of the second relay connects a described CPU, the second relay is disconnected when reaching setting value at zero clearing rolling counters forward number of times.
Zero clearing counter can directly adopt low level counting, the low level signal of exporting corresponding to voltage sample.
About the reset of the second relay, can further increase a pass point, for example described tapered end be provided with for second relay reset code-disc, and be provided be connected in a CPU for indicate second relay disconnect indicator lamp.
If two pass points meet the encryption requirement of using object completely above, about the reset of relay, can adopt simple reset, but preferably adopt it as the 3rd pass point, to assist two pass points above.
Except the type of alarm that CN201794392U records, as a CPU as described in simple is connected with warning circuit.
A kind of optimal way is that described warning circuit comprises 3G or 4G module, and for the selected user mobile phone of association, user can know that key is stolen in the very first time, thereby reports to the police processing.
About charging, characterize in other words the voltage of super capacitor charge volume, as pass point, can carry out multiple key strokes cipher mode that corresponding charge volume superposes that superposes, can also assist decimal place charge volume, to improve cryptographic capabilities, the decimal place is here expressed as the position that is less than a key turns stroke.As shown in Figure 4, in described lock core base hole, corresponding to the segmental arc of lock core rotational travel, be provided with scale, quantitatively to charge, the super capacitor voltage producing like this can have higher encryption level.
For convenience of operation, described scale comprises to be marked number graduation mark and is distributed in the registration graduation mark between mark number graduation mark, and its acceptance of the bid number graduation mark is longer than registration graduation mark.The auxiliary mark of its acceptance of the bid number graduation mark number, can read intuitively, and registration graduation mark can be calculated and obtains reading according to mark number graduation mark.But this case registration graduation mark, for reference, corresponding to voltage range, does not need to super capacitor, to charge accurately, avoids because the inconsistent problem of charging that environmental change causes yet.
Meanwhile, set the structure of super capacitor electric discharge and also consider this problem, be that operation inevitably can produce the operation that error, especially precision are not high.
Registration graduation mark reference once mode arranges, and the number that adjacent mark is counted the registration graduation mark between graduation mark is 2.Registration graduation mark is mainly used to reference, with mark number graduation mark, be as the criterion, during use, avoid the voltage increment that uses registration scale to represent as far as possible, and take voltage increment corresponding to mark number graduation mark as setting, the operation that registration graduation mark is as a reference user-friendly to designs.
