In order to the meaning of each technical measures of clear interpretation, be first explained as follows:
Inventor studies anti-theft technique for many years, existing achievement is that normal door is without mechanical key, but by the mode that electronics telecontrol engineering or phone open the door, under normal circumstances, the power set be installed in door promote lockset and realize opening the door, but also retains traditional door-opening mode of mechanical key, its objective is when electronic technology goes wrong, can also open the door and enter house, as a kind of compensating mode of enabling, but lockhole is cover in the ordinary course of things, if will be opened the door by lockhole, onsite alarming device and message handler all can start warning, possesses recognition function, if the open alarm gone wrong because of electronic technology, one of own side is had to exist, there will not be fear, otherwise, lockhole when electronic technology does not go wrong opens the door, it is largely crime behavior, now do not input correct electronic signal, warning and photorecorder will be started.
After this measure is implemented, form multi-functional.
First heavy function is pre-warning: because lockhole is covered, crack lockhole and first must take off touch sheet, hand has just contacted touch sheet and just produced touch signal, starts warning start-up circuit and forms pre-warning, increase the psychological pressure of perpetrator, make it to receive hand in advance.
Second heavy function is formal warning: when pre-warning fails to prevent, if continue to crack lockhole, touch sheet souththern pine moves, the button of lock-switch no longer makes contact change by the compressing of touch sheet, thus produces warning enabling signal, and if cruelty is forced open the door, when improper enabling, door and the firm displacement of doorframe, the button of door switch no longer by the compressing of doorframe, thus produces warning enabling signal.
Triple functions is telephone call: telephone call has been formal warning, occur in touch sheet to loosen, after lock-switch produces warning enabling signal, or the door in improper enabling situation and doorframe displacement, door switch produces warning enabling signal, thus starts radio transmitter circuit, after receiving signal by message handler, notify related personnel in time, to do corresponding measure.
Quadruple function is onsite alarming and shooting record: shooting record herein comprise conclude a case before record and overall process record, just just start record in generation event, be very suitable for general family, and onsite alarming device also possesses trace property, just onsite alarming is started in generation event, house owner people early has preparation to allow perpetrator understand, thus receives hand in advance, avoids significantly producing consequence.
To the meaning of each technical measures, concrete condition is explained as follows further:
One, mixed type floating charge source of stable pressure; it is the voltage-stabilized power supply that alternating current-direct current shares; it contains rectification unit, overvoltage voltage-limiting protection unit, overvoltage fast tripping protection unit, voltage regulation unit, charge/discharge unit and balance diode; civil power is powered to other unit after over commutation; have run into thunderbolt or overvoltage time; overvoltage fast tripping protection unit starts the fast tripping protection formed overvoltage voltage-limiting protection unit immediately; the voltage-limiting protection of overvoltage voltage-limiting protection unit is then the Supplementary and perfect to pressure fast tripping protection unit, jointly forms the overvoltage protection to voltage regulation unit input.Charge/discharge unit solves the contradiction that float charge voltage is high and discharge voltage is low, and balances the utilization of diode, achieves alternating current-direct current and shares, be independent of each other again, allow arranges for keeping good service behaviour at any time.
(1), rectification have employed the form of decompression capacitor, decompression capacitor (902 in Fig. 8) withstand voltage for being greater than 100V, then becomes rectification through rectification circuit (903 in Fig. 8) and export, for rear class is powered.
(2), the explanation of overvoltage voltage-limiting protection unit and overvoltage fast tripping protection unit, the principle that namely lightning protection anti-over voltage ability is strong:
Overvoltage voltage-limiting protection unit and overvoltage fast tripping protection unit, constitute " fast tripping protection function ", excellent performance, has very strong lightning protection overvoltage capabilities.
Overvoltage voltage-limiting protection unit is made up of overvoltage voltage-limiting protection triode (904 in Fig. 8), upper inclined resistance (905 in Fig. 8), overvoltage voltage-limiting protection Zener diode (906 in Fig. 8); Overvoltage fast tripping protection unit is made up of overvoltage fast tripping protection controllable silicon (907 in Fig. 8), triggering Zener diode (908 in Fig. 8).
1, the principle formed is: if be struck by lightning and cause the emitter voltage of overvoltage protection triode too high; after exceeding the door triggering Zener diode; trigger Zener diode conducting; thus overvoltage fast tripping protection controlled silicon conducting is triggered; immediately to the base stage short circuit of overvoltage voltage-limiting protection triode; make the complete no-output of overvoltage voltage-limiting protection triode, namely 78 serial integrated stable voltage circuit input no-voltages, form lightning protection overvoltage fast tripping protection.
2, fast tripping protection function why is called; because once the emitter voltage of overvoltage protection triode is too high; overvoltage fast tripping protection controllable silicon is itched conducting immediately; and there is very strong positive feedback; can rapidly by the base stage short circuit of overvoltage voltage-limiting protection triode; protection whole process is very rapid, and protection thoroughly, realizes sealing up a door completely.
3, overvoltage fast tripping protection controllable silicon and triggering Zener diode form fast tripping protection function, when during normally to work without overvoltage, are in open-circuit condition; there is no electrical wear; can not damage, and trigger the voltage of voltage stabilizing value higher than overvoltage protection transistor emitter of Zener diode, so be also open-circuit condition; do not have electrical wear can not damage yet; and once there be overvoltage, start immediately, become fast tripping protection; so in normal state, overvoltage fast tripping protection unit is all standby at any time.
4, the automatic restorability of overvoltage fast tripping protection silicon controlled is good.Reason is after producing protection; overvoltage voltage-limiting protection triode no-output; triggerless voltage; in addition overvoltage fast tripping protection controllable silicon anode has resistance, by automatically losing self-sustaining electric current, reverts to open-circuit condition voluntarily; if be again struck by lightning; again start, form protection, until output voltage is normal value.
5, overvoltage voltage-limiting protection unit defines the voltage-limiting protection function of protection against lightning strikes to thunderbolt, the perfect further protection to integrated circuit.
Its reason is; the base stage of overvoltage voltage-limiting protection triode has overvoltage voltage-limiting protection Zener diode over the ground; therefore overvoltage voltage-limiting protection triode exports by clamper; this overvoltage voltage-limiting protection Zener diode has carried out pressure limiting to shoving of thunderbolt generation, is the further Supplementary and perfect to " fast tripping protection ".
(3), voltage regulation unit can adjust the explanation of standard float charge voltage value:
Voltage regulation unit is made up of resistance (917 in Fig. 8) inclined under resistance (912 in Fig. 8) inclined in 78 serial integrated stable voltage circuits (909 in Fig. 8), output voltage accurate adjustment, output voltage accurate adjustment.In defeated voltage accurate adjustment, resistance and the use of inclined resistance under output voltage accurate adjustment partially, on reference voltage, can realize output voltage and adjusts flexibly, to realize the normal voltage needed for battery floating charge, as 6.6 volts; 13.8 volt etc.
(4), the explanation of charge/discharge unit:
Be made up of floating charge resistance (918 in Fig. 8), battery (919 in Fig. 8), discharge diode (920 in Fig. 8), rectify control diode (921 in Fig. 8), base stage controlling resistance (928 in Fig. 8), realize discharging to the science floating charge of battery and science.
1, the output of 78 serial integrated stable voltage circuits and the voltage of floating charge point can adjust to standard float charge voltage, realize science floating charge, floating charge resistance mainly plays two effects, one is to large power supply current limliting, two is that the voltage realized between floating charge point and battery is isolated, thus when there being interchange, both can floating charge, can working power be become again.
2, battery standard float charge voltage is 13.8V, but voltage exports as 12V during battery discharging, and the operating voltage of electronic equipment also can only between 12V, because if operating voltage is higher than 12V, only having in galvanic situation, electronic equipment may because storage battery pressure ratio alternating voltage is low cisco unity malfunction, therefore, when only having direct current, the electric discharge of battery can not produce large pressure drop, otherwise electronic equipment cisco unity malfunction, this electronic equipment special to some, as antitheft class, security personnel's series products is very disadvantageous, because antitheft or security personnel become illusory, the consequence produced is serious, and direct current charge-discharge unit of the present invention solves this problem well, because discharge diode is PNP triode, during its conducting and battery discharging time, the pressure drop of discharge diode is very little, for 0.1V, can ignore, very large pressure drop can not be produced, battery discharging triode is made with it, valuable pressure drop can not be lost.
3, the principle forming discharge and recharge is: the base stage controlling resistance of discharge diode and rectify control diode, just there is such principle: have voltage when rectification exports, just show now have alternating current to exist, battery should be floating charge state, discharge diode is because be PNP triode, its base stage has because there is high pressure to exist, so can not conducting, colelctor electrode would not have voltage to export.When rectification exports no-voltage, i.e. discharge diode base stage no-voltage, it just constitutes the form of an electronic switch, forms conducting state, and battery starts electric discharge, colelctor electrode output voltage, so very reliably distinguish two stages of floating charge and battery discharging.
(5), balance diode (930 in Fig. 8) to play an important role in this circuit arrangement, that the voltage of floating charge point is reduced to operating voltage, when there being alternating current, electronic equipment is normally worked, battery charges normal, and when only having direct current, be only that DC voltage is without balancing diode, thus can not produce additional pressure drop, alternating current-direct current is independent of each other.And diode is the 0.7V of constant substantially, fine debugging, its dynamic electric resistor is little, little to load effect, can not produce output voltage fluctuation, thus ensure that the correctness that alternating voltage exports, and when storage battery power supply, only through the discharge diode that pressure drop is little, without balance diode, so pressure drop can not be produced, therefore ensure that combined-voltage exports stable.
Two, the principle of pre-warning generation:
Because lockhole is covered on anti-theft safety door, and theft is under normal circumstances all by lockhole for it, therefore when hand just contacts touch sheet, touch signal will be produced, this signal takes out after amplification through early warning start-up circuit, and direct triggers presence warning circuit sends warning and prevents.
1, the lead-out wire of touch sheet connects the low valve valve end of preposition oscillator after commissure electric capacity, enter oscillating circuit inside, produce accurate vibration, cause vibration failure of oscillation or seriously change, make the OUT pin of oscillating circuit and preposition output (07 in Fig. 1) have high-order output.This high-order output becomes the power supply of onsite alarming device after amplifying circuit, and forming on-the-spot warning and prevent, warning now, is also the incipient stage that perpetrator has crime behavior, is therefore pre-warning.
In early warning start-up circuit, oscillating circuit is reliable, touch-sensitive, and its reason is that oscillating circuit is not when there being touch signal, oscillating circuit is in vibrational stabilization state, and after having touch signal, great change inherently occurs oscillating operation condition, output must have high-order output.The direct-to-ground capacitance of output end of oscillating circuit has interference effect, improves this grade of performance from another angle.Oscillating circuit is structurally being combined into of analog circuit and digital circuit, analog functuion and logic function compatibility is integrated, and produces and vibrates accurately, a power supply can be shared with amplifying circuit, and oscillating circuit maximum output current 200mA, carrying load ability is strong, use reliable, the life-span is long.
2, amplifying circuit is formed by two inverter series, strengthen shaping and amplifying power, because phase inverter quiescent dissipation is extremely low, during input signal change, can automatic fitration reconcile, so the voltage exported can be protected, antijamming capability is strong, reducing time delay, so when there being signal, exporting reliable in time.The sensitivity of phase inverter adjusts very well, and a sensitivity adjustment resistance joined by each phase inverter, and its sensitivity resistor resistance is large, sensitivity step-down, and resistance is little, and sensitivity raises, and has very strong adjustable.
As long as thus there is crime behavior, just reliably have issued while hand just contacts touch sheet and warn prevention in advance, form psychological pressure to perpetrator, make it to understand that house owner early has preparation, avoid to a great extent continuing stolen possibility.
Three, formal reason of reporting to the police is produced: formal warning fails to produce when preventing in pre-warning, started by lock-switch and door switch and formed, be arranged on above door lock hole, lock-switch below touch sheet is an emphasis, fail in the crime behavior of prevention in pre-warning, it starts the key of reporting to the police.
Pre-warning fail prevent crime behavior, if continue to crack lockhole, when touch sheet souththern pine moves, the button of lock-switch no longer makes contact change by the compressing of touch sheet, lock-switch has three contacts, a contact lead-out wire of lock-switch and constant close contact lead-out wire, another contact lead-out wire of lock-switch and normal pin contact lead-out wire, therefore when the button of lock-switch no longer suffers oppression, two contacts communicate, thus produce warning enabling signal, while excitation onsite alarming device, start radio transmitter circuit and send tele-alarm signal, and circuit is shot with video-corder in startup.
Door switch is arranged on door and doorframe junction, forcing open the door when improper enabling, door and the firm displacement of doorframe, door switch contact changes, door switch has three contacts, a contact lead-out wire of door switch and constant close contact lead-out wire, another contact lead-out wire of door switch and normal pin contact lead-out wire, therefore when the button of door switch no longer suffers oppression, two contacts communicate, thus produce warning enabling signal, while excitation onsite alarming device, start radio transmitter circuit and send tele-alarm signal, and circuit is shot with video-corder in startup.
Lock-switch, door switch have allowed warning accomplish more scientific after matching with the existing achievement of inventor, and its reason is:
1, can not produce and make us terrified wrong report, this is the most important.Its reason is, the enabling (opening with improper door) that is absent from the scene of owner within doors, are all crime behaviors, warning is now very crucial.
2, very reliable because normal life enabling at closing time, do not need artificial additional move, do not affect the normal habits and customs of people, thus do not affect the normal work that security system is started at every turn.
3, the starting of lock-switch is sensitive and reliable, just can report to the police, thus loss is reduced to minimum when crime behavior is not accomplished.Because touch sheet lock-switch contact when loosening will change and produce warning initiating signal, forcing open the door under abnormal condition, door and the firm displacement of doorframe, door switch contact changes and produces warning enabling signal.
Four, at home unmanned or surrounding nobody time event, notifying related personnel in time, is very important, and it is convenient to related personnel and makes corresponding counter-measure in time, avoids producing more serious consequence.
In coding integrated package in radio transmitter circuit and message handler, the decoding integrated package of radio receiver circuit has such relation.
In 8 bit codes of coding integrated package, wherein 7 is launch fixed code, wherein one is launch variation code, radiating portion is when launching, launch two subcategory numbers, wherein transmitter code is 7 transmitting fixed code wherein for the first time, and the first subcategory number of the transmitting variation code of, the code that second time is launched is 7 constant transmitting fixed code, and one is launched the coded signal after changing code variation.Thus the decoding integrated package in matched radio receiver circuit also should be that 7 fixed code and one change code.
1, the power supply of radio transmitter circuit is provided by lock-switch, lockhole is cracked when warning continuing of cannot preventing in advance, the button of lock-switch no longer makes contact change by the compressing of touch sheet, lock-switch is off shape by original being closed into, a contact of lock-switch and the power supply of constant close contact lead-out wire and early warning start-up circuit are connected together, the power end of radio transmitter circuit is connected to after the isolating diode of Ji Changjiao contact, another contact lead-out wire connection radio transmitter circuit of lock-switch, therefore, after lock-switch has become disconnection from connection, two contacts communicate, radio transmitter circuit is energized, annular oscillation circuit starts rapidly, because the change code of coding integrated circuit has terminated in the output of annular oscillation circuit, therefore, coding integrated circuit is no longer fixing code, thus improve safety factor, stop the interference of the various electrical equipment of social upper existence, make signal transmission more accurate.
Dicode is sent in order to allow radio transmitter circuit, designer aims at this line design one and forms a kind of annular oscillation circuit by gate circuit, the principle of its vibration is: in power on circuitry in a flash, the input of first gate circuit (40 in Fig. 4) is high-order, because differential capacitance (42 in Fig. 4) can not the reason of transition in transition, a high position will be delivered to rapidly the input of second gate circuit (43 in Fig. 4), thus make the output of second gate circuit (43 in Fig. 4) for high, the output of the 3rd gate circuit (44 in Fig. 4) is low, thus the input of first gate circuit (40 in Fig. 4) continues as low and keeps a period of time, within this time, the output of the 3rd gate circuit (44 in Fig. 4) is charged through the output of adjustable resistance (41 in Fig. 4) to first gate circuit (40 in Fig. 4) by differential capacitance (42 in Fig. 4) again, (because this gate output is low level), after differential capacitance charging, electric capacity becomes off-position, second gate circuit input becomes low level from a high position, at this moment the state between each gate circuit takes a turn for the worse, state is now that second gate output is for high-order, 3rd gate output is low level, first gate output is high-order, also because differential capacitance can not the principle of transition, this state will keep a period of time, the physical process of this period is that the output of first gate circuit can be crossed adjustable resistance and carry out reciprocal charging to differential capacitance, form the later half cycle of vibration.Principle like this carries out the second time cycle, and the later cycle.
In foregoing circuit, in order to make vibration starting of oscillation easy, make vibrational stabilization reliable, designer has done following adjustment change, one is be designed to electrodeless by the differential capacitance in circuit, decrease the electric leakage composition of electric capacity, improve Q value, two is add adjustable composition to the time constant of vibration to be beneficial to adjustment.Test shows that this circuit and overall circuit are worked good, and has very strong exploitativeness.
In measure 1, annular oscillation circuit defines such annexation with coding integrated circuit, the coded portion of coding integrated circuit has been divided into two parts, a part is the fixed code connected in advance, this fixed code can ground connection, also can connect power supply, flexible and changeable, another part is the change code be connected with annular oscillation circuit.When manual operation transmitting or alarm switch contact change, annular oscillation circuit vibrates, and the change code end of coding integrated circuit just becomes two states, and integrated circuit of at this moment encoding just can only become dicode two kinds output by a kind of single code transmissions from former.By the excitation to modulating tube, reach the object of dicode modulate emission.
2, the radio receiver circuit in message handler, reliably can decode the coded signal that radiating circuit sends, the principle of twice decoding produced is: 7 bit codes in integrated 8 bit codes of decoding have been connected into decoding fixed code (612 in Fig. 6), a wherein bit code is become receipts twice signal decoding and becomes code end, (610 in Fig. 6).When original state, the code bit presented all the time wherein originally becoming code end for decoding is and launches a stationary state change coded signal of code, and to occur to become code be just generation after receiving signal.In an initial condition, PNP triode is because have bias current, (being namely that base stage is connected to resistance to earth), so colelctor electrode has output, it exports connected code bit original state is 1 state, at this moment reliably can not only receive 7 fixed code, the coded signal that radiating portion change code bit sends for the first time can be received simultaneously.After receiving the first signal sent, at this moment the first output of decoding code integrated package, be become code control end (664 in Fig. 6), export high signal, this signal produces high-order to the base stage of PNP triode, this pipe is produced and seals up a door, because PN joint produces reverse bias, this pipe collector no-output, because the second code signal that the transmitting variation code of coding integrated package sends is 0, therefore, decoding becomes a code termination resistance to ground wire, also be low level, thus it is corresponding to make connected code line and the second time of radiating portion become coded signal, thus second change coded signal that radiating portion sends can be received.
Decoding integrated package in the present invention has two outputs, wherein first output, and being also called is automatic changing code control end, and the output of this end is connected with PNP triode (668 in Fig. 6).Another one is that second exports, and is namely the output of radio receiver circuit, and this output connects with reception programme control circut, is directly export decoded result.The structure of this circuit can realize receiving the requirement becoming code.
3, also have in message handler and a kind of receive programme control circut (522 in Fig. 5), connect the storage number end of the lead-out wire from telephone key rosette copper paper tinsel and dialing integrated package.
Dialing integrated package in telephone has following function, one is to store multiple telephone number, when oneself storage is complete in advance (the present invention can utilize former existing phone to store this integrated circuit), as long as add a triggering signal to its storage pin, this sheet will control to send a phone number dial automatically, so its multiple storage number ends have been connected on the multiple outputs in reception programme control circut respectively, the dialing output of this integrated circuit has been connected on telephone, so when starting telephone call, receive the multi-section telephone number that multiple outputs of programme control circut can start this element storage outwards to dial.The model of a lot of dialing integrated package has powerful storage number function, and a lot of integrated circuit storage capability is all more than 10 numbers, so phone circular function is very powerful.
Be a very serious thing owing to producing telephone call, if wrong report, unnecessary terrified by causing, consequence is very serious.And use now the apparatus of remote control many; as locking of protecting car door; with unblock etc.; all want straighforward operation; just define possible interference source, and after radio transmitter circuit and message handler cooperatively interact, stop interference source; if there is alarm call must be non-normal door, thus substantially increase the confidence level that the present invention reports to the police.
Five, on-the-spot alarming effect is remarkable, simultaneously with shooting record, is convenient to understand course of event afterwards, very beneficial to solving a case.
Shoot with video-corder circuit by starting or door, electronic switch, photorecorder, forming with the rest-set flip-flop of display, time controller, manual control switch.
The output of warning start-up circuit, another contact lead-out wire of alarm switch, a contact lead-out wire of manual control switch, time controller receive the input starting OR circuit respectively, as long as or the characteristic of door has an input to meet condition, so just have output, therefore be no matter that warning start-up circuit in pre-warning has output, or alarm switch contact there occurs change, or manual control switch contact changes, all can start photorecorder, form shooting record.
1, time controller (27 in Fig. 2) is the instrument with time controling and display, as long as preset the time, it will output signal, after startup or door (20 in Fig. 2), open electronic switch (in Fig. 2 24), then allow photorecorder (25 in Fig. 2) work, and start onsite alarming circuit.
2, the principle of shooting record overall process is produced: although hand have left the lockhole cover plate above lockhole after forcing open the door, but the alarm switch button under being pressed in theft protection plate is no longer by the compressing of lockhole cover plate, there occurs change, lock-switch is closed, so opened photorecorder logging.And forcing open the door under abnormal condition, door and the firm displacement of doorframe, just opened photorecorder.
3, displaying principle is had after shooting record before generation case: in Fig. 2,26 is a kind of rest-set flip-flops with display, thus there is Memorability, each or door has output to open electronic switch (in Fig. 2 24) time, the rest-set flip-flop having display is triggered in capital, so once after rest-set flip-flop is triggered, additional LED can luminescence display.
4, the principle of shooting record writing time before generation case: at every turn shoot with video-corder control or door when having output to open electronic switch, signal is had to trigger time controller, so automatically can record the moment of generation, thus each hand contact lockhole cover plate all can produce and shoot with video-corder and onsite alarming.
5, all very strong tracing properties of onsite alarming device, and when nil case non-transformer, therefore circuit can not damage.Use audio-frequency power amplifier in onsite alarming device, simple in circuits, quiescent dissipation is low, and operating voltage range is wide, and peripheral cell is few, and voltage gain adjustment degree is wide, to advantages such as the distortion factor of sound are low.
After the invention process, improve the security performance of anti-theft safety door, outstanding advantage is as follows:
1, anti-theft safety door and alarm achieve the combination of science; possesses the advantage of two kinds of protectors; usually both people can be kept outside the door; run into other people when committing a crime; two kinds of warnings can be sent; very significant to " initiatively the protectiveness " that increase anti-theft safety door, so this product finishes the situation of the passive defence of anti-theft safety door completely, improve security personnel's performance of anti-theft safety door all sidedly.
2, mixed type floating charge source of stable pressure is the power supply that alternating current-direct current shares, and makes the service behaviour that equipment keeps good at any time, its be mainly manifested in following some: (1), lightning protection effect are more much better than conventional anti-thunder tube.Its reason one is lightning protection function.Two is that the model of the anti-thunder tube that " breakdown voltage " is low has not easily been bought, and the model scope of triggering Zener diode of the present invention is extremely wide, is easy to " puncturing " magnitude of voltage needed for supporting one-tenth, so be easy to the protection of supporting one-tenth breakdown voltage less than 30 volts.Three is that the present invention has " quick-break " and pressure limiting duplicate protection, thus effective.
(2), maintain the advantage of 78 serial integrated stable voltage circuits, enhance the overvoltage capabilities of 78 serial integrated stable voltage circuit inputs.
(3), adapt to wide, have wider adaptive capacity than traditional voltage-stabilized power supply, high at the voltage that meets accident, can not damage.And at voltage, lower ground side and period also can normally work.
(4), available adjustment exports generation the voltage stabilizing value of decimal, is convenient to, to the floating charge of battery science, realize alternating current-direct current and share, makes equipment ensure that good service behaviour at any time.There is overcurrent protection simultaneously, be fruitful or other electronic products supporting after have excellent performance.
(5), easily produce.Reason one have employed complex function, and simple in circuits is compact; Two is because the debug point in circuit is few.Three is that debug point very easily quantizes, and debugging scope is loose.
(6), cheap, more cheap than a lot of satisfactory a lot of voltage-stabilized power supply a lot.
3, Forewarning Measures excellent performance can ensure this functional effect.Reason is highly sensitive, can ensure that early warning start-up circuit will start immediately when there being people to want to destroy lockhole.
4, on-the-spot alarming effect is remarkable, simultaneously with shooting record, is convenient to understand course of event afterwards, very beneficial to solving a case.
5, lock-switch and door switch reliably sensitive, can not report by mistake.Because after coordinating with existing achievement, there is automatic recognition property.The warning produced when owner is absent from the scene may be only crime behavior.Otherwise behavior of not committing a crime, switch can not send signal, at this moment because install the structures shape of switch.Due to the intrinsic property of switch, when shift knob is being subject to oppressing and the change that contact occurs inherently to occur when not suffering oppression, lay special stress on protecting the lockhole be the most easily cracked.
6, after radio transmitter circuit and message handler cooperatively interact, stopped interference source, reported to the police more reliably credible.Avoid thing and the situation that in family, Nobody Knows of occurring, because if crack lockhole, when pre-warning cannot be prevented, lock-switch starts immediately, message handler notifies personnel outside in time after receiving alarm signal, allows personnel outside learn situation in family in time, to make corresponding measure.
