Embodiment
For making purpose of the present invention, technical scheme and advantage clearer, clear and definite, referring to the accompanying drawing embodiment that develops simultaneously, the utility model is further described.
Be illustrated in figure 1 as method flow diagram of the present invention, it comprises the following steps:
A: receive the radiofrequency signal that mobile phone constantly sends;
Mobile phone self can constantly be launched radiofrequency signal, so guaranteed the design basis of this method.
B: the energy that improves the radiofrequency signal that receives;
Because radiofrequency signal is fainter, so first radiofrequency signal is passed through " energy storage device " energy storage, improve energy.
C: radiofrequency signal is converted to simulating signal;
D: simulating signal is amplified;
This simulating signal is also smaller signal, so this simulating signal will be amplified to by " signal amplifier " signal that " signal comparator " can recognize.
E: the analog-signal transitions after amplifying is digital signal, and high level or low level by relatively judging with reference voltage;
Simulating signal after amplification is input to " signal comparator " signal is become digital signal.When the close mobile phone burglar alarm of mobile phone, relatively (reference voltage can be adjusted for signal after amplification and reference voltage, in order to control the scope that mobile phone is reported to the police apart from mobile phone burglar alarm), this signal is during more than or equal to reference voltage, and signal comparator is output as low level; During away from mobile phone burglar alarm, this simulating signal becomes very little voltage when mobile phone, and during less than reference voltage, signal comparator is output as high level.
F: receive high level and drive alarm and make actuation of an alarm, receive low level and do not drive alarm and make actuation of an alarm.
The high-low level of signal comparator is input to " hummer control circuit ", when input signal was high level, hummer rang, and when input signal was low level, hummer did not ring.Realize that mobile phone is away from the function of mobile phone burglar alarm alarm.
Be illustrated in figure 2 as the structured flowchart of mobile phone burglar alarm of the present invention, the construction module that described mobile phone burglar alarm comprises has antenna 11, energy storage device 12, diode peak envelope detecting device 13, signal amplifier 14, signal comparator 15, hummer control circuit 17, hummer 18, wherein, modules is linked in sequence, and this mobile phone burglar alarm also includes in a reference voltage generator 16, these reference voltage generator 16 input signal comparers 15.
When stating mobile phone burglar alarm in the use, at first, open this alarm, because mobile phone can constantly send radiofrequency signal, when mobile phone was reported to the police robber's device near preventing mobile phone, mobile phone burglar alarm just received this faint radiofrequency signal by antenna 11.
Because radiofrequency signal is fainter, antenna receiving signal very little (being generally the milliwatt level) so first radiofrequency signal is passed through the energy storage device energy storage, improves energy.The energy approach that provides that the present invention is selected is to increase by an inductance, the first inductance L 1 as shown in Figure 3, and an end ground connection of this first inductance L 1, the other end connects picking out of antenna 11 and holds 110.
After namely boosting after signal improves through energy, namely be transfused in diode peak envelope detecting device 13 radiofrequency signal is converted to simulating signal.Referring to Fig. 3, this diode peak envelope detecting device 13 comprises a diode D1, a capacitor C 1 and a resistance R 1, the positive pole 131 of described diode D1 is the input end of diode peak envelope detecting device, negative pole 132 is the output terminal of diode peak envelope detecting device, and the positive pole 131 of described diode has public wiring point with the ungrounded end 121 that picks out end the 110 and first inductance of antenna; Described capacitor C 1 and resistance R 1 parallel connection, and the negative pole 132 of a terminating diode D1, other end ground connection.
One of them core technology of the present invention is diode peak envelope detecting device 13, and the below says the principle of diode peak envelope detecting device 13 in detail: detection process is exactly that signal source is by the alternately repeating process of diode D1 to capacitor C 1 charging and 1 discharge of 1 pair of resistance R of capacitor C in fact.Please participate in Fig. 4, suppose input signal for sinusoidal wave, we explain detection process by figure:
As input signal U
iStart from scratch when increasing, because the high-frequency resistance of capacitor C 1 is very little, U
iAlmost all be added to the two ends of diode D1, C1 doubly charges, the conducting resistance R of D1
DVery little, charging current is very large, constant R during again because of charging
D* C1 is very little, and the Voltage Establishment on electric capacity gets very fast, and this voltage oppositely is added in again on D1, and this moment, the voltage on D1 was voltage poor on signal source voltage and electric capacity, and the voltage on electric capacity equals U
iThe time, D1 by, along with U
iContinuation descend, there is certain closing time in D1, during this period in capacitor C 1 electric charge of conduction period storage is discharged by R1.Because of discharge constant R
D* C1 is larger, discharge slower, and when capacitance voltage decline is few, U
iNext cycle arrive, work as U
iDuring greater than the voltage on electric capacity, D1 is conducting again, and capacitor C 1 is got back additional on the basis of original stored charge amount, and the voltage on electric capacity is further improved.Then, continue above-mentioned discharge, charging process, until the voltage on capacitor when ending with D1 the discharge charge amount of C1 equate, just reaching dynamic balance state is steady-working state.
Diode current ID comprises average weight I
avAnd high fdrequency component.I
avThe average voltage U that the resistance R of flowing through 1 forms
av, it is exactly the useful output voltage of wave detector.Because high frequency ripple voltage is very little, this voltage just almost is equal to the output voltage of wave detector.
Continuation is referring to Fig. 1, after radiofrequency signal is converted to simulating signal, because this simulating signal is also smaller signal, so this simulating signal will be amplified by signal amplifier 14, about the standard of determining of signal amplifier 14 enlargement factors be: the simulating signal that satisfies after amplifying can reach the signal that signal comparator 15 can recognize.Change it into digital signal after signal comparator 15 identification signals, and the digital signal that conversion obtains is compared with the extraneous reference voltage of inputting, when mobile phone is closer apart from this mobile phone burglar alarm, energy through the signal after amplification and conversion process is just more intense, this moment and reference voltage are relatively just greater than reference voltage, and described signal comparator 15 will be exported a low level; And when mobile phone was distant apart from this mobile phone burglar alarm, just more weak through the energy of the signal after amplification and conversion process, this moment, the energy of signal just may be less than reference voltage, and signal comparator 15 will be exported a high level.The size of described reference voltage can be regulated as required, just must guarantee when reference voltage is larger the distance of mobile phone and mobile phone burglar alarm will be very near could output low level, the distance of mobile phone and mobile phone burglar alarm just can slightly far some can guarantee output low level when reference voltage is less.
Hummer control circuit 17 is selected whether to drive hummer according to the low level of signal comparator 15 output or high level and is made actuation of an alarm, when hummer control circuit 17 receive be low level the time just do not drive hummer 18 work, when hummer control circuit 17 receive be high level the time will drive hummer 18 work, thereby prompting is reported to the police, and guarantees the security of mobile phone.
Should be understood that, application of the present invention is not limited to above-mentioned giving an example, and for those of ordinary skills, can be improved according to the above description or conversion, and all these improve and conversion all should belong to the protection domain of claims of the present invention.
