When the car owner need carry out theftproof monitoring to automobile, open the power supply of warning device earlier, the number that need put through when input is reported to the police on the panel of mobile phone or fixed line again, and connect once, be provided with errorless with affirmation, then this warning device is put in that a shelter gets final product in the car, this moment, this warning device was just in running order.In case automobile is invaded and harassed, sensor is after detecting outside invasion signal, with the detection signal that obtains, treated circuit is exported to alarm control circuit with certain level signal after the signal processing and amplifying starts working it, producing one group of trigger pulse drives and is installed in mobile phone and " redials " micro electromagnetic switch on the function key, the micro electromagnetic switch motion, " redialing " key is pressed, and mobile phone is dialled mobile phone, the phone that is the owner by the number of establishing in advance.After the owner hears dialing tone, just can judge that from the shown number of mobile phone the article of being monitored have been subjected to extraneous the invasion, the owner can press logical this device of " conversation " keyed jointing, listen to the real-time acoustic information of monitored automobile environment of living in, judge whether automobile is in danger, in time to report to the police to public security organ and relevant department.
The circuit working principle is described below:
When automobile or car etc. was not subjected to extraneous the invasion, nobody touched automobile, and then automobile remains static, and sensor Y does not have signal output.Select resistance R 3And resistance R 2Resistance make IC 1The positive input terminal current potential be lower than below the 0.7V IC then 2Normal phase input end because resistance R 5Effect and be in electronegative potential, so, IC 2Be output as electronegative potential; In like manner, IC 3Output also be electronegative potential, IC 4Reset terminal R (4 pin) also be electronegative potential, IC 4Output terminal not have signal output also be electronegative potential, IC 7The in-phase input end electronegative potential, IC 7Output end vo be electronegative potential, at this moment, with IC 7The phase inverter Q that output terminal links to each other 1Base stage also is an electronegative potential, Q 1End, electromagnetic switch is failure to actuate, and does not carry out dialing alarm.
When automobile was subjected to invading and harassing, sensor Y was owing to being vibrated the interchange variable signal that produces certain amplitude, and this signal is through VR 1Dividing potential drop is after C 1, R 4Be added in IC 1Inverting input by IC 1Amplify and through D 1C is given in rectification 4Charging is along with C 4The raising of charging voltage, IC 2After the current potential of in-phase input end raises and surpasses the current potential of inverting input, IC 2Output terminal become noble potential by electronegative potential, power supply is through IC 2, D 2Beginning is to C 5Charging, C 5The very fast rising of voltage and surpass IC 3The inverting input current potential, IC 3Output terminal also become noble potential by electronegative potential.With IC 3The IC that output terminal links to each other 4Reset terminal R become noble potential by electronegative potential, IC 4Start working.
IC 4Be a low frequency multiple-harmonic generator, when reset terminal R is in noble potential, it will periodically produce and export the square wave with certain width, and the square wave of output is added in IC 7In-phase input end, make IC 7Output terminal uprise the phase inverter Q that is attached thereto by low 1Conducting drives the redial key that mobile phone is pressed in the electromagnetic switch action, puts through another mobile phone that the car owner establishes in advance, reaches the purpose of warning.
In circuit, the receiver voicefrequency circuit of Vi emission mobile phone taking alarm wherein, IC 8, IC 9And peripheral circuit is in order to realize the sound monitoring function.Its course of work is: before holding state and car owner did not connect alarm mobile phone, the Vi place did not have input signal, IC 8In-phase input end because R 12Effect be in electronegative potential, make its output terminal also be in electronegative potential, at this moment, IC 9Inverting input because R 15Effect also be in electronegative potential, then IC 9Output in cut-off state, do not influence IC 4Work.After the car owner hears cell-phone bell sound, be other phone or as can be seen from the alerting signal of automobile from the number of handset displays.If alerting signal, the car owner just can according to circumstances take appropriate measures, wherein when the sound in the needs monitoring car, press " talk key " and just can connect the mobile phone of warning, send some sound gently facing to microphone, the audio monitoring circuit can be from the microphone voicefrequency circuit picked up signal, this signal is through capacitor C 6Be coupled to IC 8In-phase input end and the current potential that causes its output terminal change between V-and V+ along with the variation of sound signal, and by D 3Be added in IC after the rectification 9Inverting input, make inverting input become noble potential, and IC by original electronegative potential 9Output terminal then become electronegative potential by noble potential, this moment IC 4Reset terminal through IC 9Made IC by shorted to earth 4Quit work, its output terminal (3 pin) remains on low-potential state, and alarm mobile phone just remains at on-state because connect with car owner's mobile phone at this moment, monitors for a long time, hangs up mobile phone up to the car owner.The utility model alarm transmission dress unit also can be a landline telephone.
Embodiment two: referring to Fig. 4～6, Fig. 9-2 or 9-4, present embodiment is applicable to the mobile phone of the company of need by twice " OK " key realization redialing function.It is identical with embodiment one dialing cycle control circuit and audio monitoring control circuit on circuit structure, difference is: signal amplification and processing unit and alarm control circuit directly are made on the chip for cell phone and the formation of chip for cell phone redialing function key is electrically connected.On circuit structure, dial impulse and alarm control circuit also contain the signal delay circuit circuit and dial impulse produces circuit 2, delay circuit and dial impulse produce circuit to be made up of integrated circuit monostalbe trigger CD4098 and peripheral circuit, and dial impulse produces circuit multiple-harmonic generator IC 4Output 3 foot meridian capacitor C 9With resistance R 20Ground connection, IC 4The output pulse through capacitor C 9Be coupled one the tunnel through diode D 4Insert comparer IC 7Reverse input end, power supply is through resistance R 24With R 25Dividing potential drop over the ground inserts IC 7Input end in the same way, IC 4The output pulse through capacitor C 9IC is inserted on another road of coupling 5Signal end 4 pin, signal is through IC 5Postpone output and insert IC by 6 pin 611 pin, IC 6The pulse signal of 10 pin output also through diode D 5Insert comparer IC 7Reverse input end, diode D 5Backward end be connected to resistance R over the ground 23, IC 7Output be electrically connected alarm transmission unit mobile phone redialing function key, IC 53,5 pin connect power supply, 8 pin ground connection, IC 52 pin through resistance R 21Connect positive source, 1 pin ground connection, the indirect capacitor C of 1,2 pin 10, IC 613,16 pin connect power supply, 12 pin ground connection, IC 614 pin through resistance R 22Connect positive source, 15 pin ground connection, the indirect capacitor C of 14,15 pin 11
