Description
The utility model relates to a kind of vehicle wireless anti-theft warning audiomonitor of exempting to disturb residents.
Existing alarming device for automobile anti-theft all sends audible alarm by the suffered vibrations of perception automobile.Whether its obvious defects is can not differentiate to have unusual intrusion to take place in the automobile, occur to disturb, the huge sound or touch once in a while under the non-abnormal condition such as automobile, it does not send audible alarm with can making any distinction between yet, thereby produced the serious problem that disturbs residents, this alarm sound has become a kind of environmental pollution.
In view of above-mentioned, the purpose of this utility model provides a kind of vehicle wireless anti-theft warning audiomonitor, and it can make things convenient for the car owner to tell automobile whether to suffer illegal invasion, and can not send the alarm sound that disturbs residents.
The purpose of this utility model is achieved through the following technical solutions:
A kind of vehicle wireless anti-theft warning audiomonitor of exempting to disturb residents is characterized in that it comprises:
One vibration detector; One amplifier, described vibration detector is connected on its input end; One binary pair, the output of described amplifier is connected on its input end; Two control relay circuits, the output of described binary pair connect the input end of two control relay circuits respectively through two time delay circuits; Be connected in series the normal opened contact of described first relay between one radio transmitter, its power end and power supply; One phonoscope, it is connected on the input end of described radio transmitter; Be connected in series the normal opened contact of described second relay between one encode circuit, its power end and power supply, the output of encode circuit connects the input of described radio transmitter.
Described vibration detector is connected with a variable rheostat, and its series connection point connects described amplifier input terminal.
The utility model is under stand-by state, if meeting automobile is shaken, vibration detector just produces the vibration electric signal, after this signal is exaggerated binary pair is triggered and sends a pulse, two relays are satisfied electricly and are kept a period of time, with the power connection of radio transmitter and encode circuit, through transmission circuit launch respectively by the coding that encode circuit produces for the contact of two relays.The car owner is located at listening state with receiving device after receiving this code signal by the receiving device of carrying, and phonoscope sends to the car owner with sound in the car by transmission circuit, and the car owner judges according to sound in the monitoring car whether unusual invasion is arranged in the car.If no abnormal in a period of time, then two relay electric-loss return to stand-by state.
The utility model advantage is:
1. because the utility model adopts radio alarming rather than audible alarm, so the phenomenon that can not disturb residents;
2. because the utility model adopts the wireless monitor technology, the car owner can listen to the sound in the car, so be easy to distinguish whether invade phenomenon in the car, be very easy to the car owner.
Describe in detail below in conjunction with drawings and Examples:
Fig. 1 is a circuit block diagram of the present utility model; Fig. 2 is schematic circuit diagram of the present utility model.
See also accompanying drawing 1.The utility model involving vibrations detector 1, amplifier 2, binary pair 3, first time delay circuit 4, first control relay circuit 5, second time delay circuit 6, second control relay circuit 7, radio transmitter 8, phonoscope 9, encode circuit 10.Wherein: vibration detector 1 connects the input end of amplifier 2; The output of amplifier 2 connects the input end of binary pair 3; The output of binary pair 3 connects the input end of two control relay circuits 5 and 7 respectively through two time delay circuits 4 and 6; The normal opened contact of first relay is serially connected between the power end and power supply of radio transmitter 8; The normal opened contact of second relay is serially connected between the power end and power supply of encode circuit 10; The output of phonoscope 9 and encode circuit 10 connects the input of radio transmitter 8.
Foregoing circuit is contained in the shell and is fixed in the car.
See also accompanying drawing 2.The first half of figure is a control part, and following left part is a radio transmitter, and lower right section is the encode circuit of mainly being made up of coding chip 145026.Wherein: Z is solid low-frequency vibration conduction detector, it connects the base input end of amplifier N1, the output of N1 meets binary pair TWH8779, the driving circuit of electrical equipment J1, J2 is succeeded in the output of binary pair respectively through time delay circuit E1 and R5, E2 and R6, the output of phonoscope (phonoscope) WY-101 and encode circuit connects the input of radio transmitter, the normal opened contact of relay J 1 is serially connected with between the power end of 12V power supply and transmission circuit, and the normal opened contact of relay J 2 is serially connected with between the power end of 12V power supply and encode circuit.
Narrate principle of work of the present utility model below.
When car body is subjected to improper effect (as: sled car door, prize vehicle window, prize bonnet, prize baggage container, unload wheel, illegal invasion actions such as bump, cutter, brill), after solid low frequency conduction detector is found out this class signal, trigger amplification control circuit immediately, make two relays get electric and maintenance a period of time, give coded modulation radio transmitter power supply 5-6 second, make its coding emission, the owner of notice outside car; 5-6 is the J2 dead electricity after second, power 30-40 second for automatically highly sensitive high-fidelity observation circuit by the normal opened contact of J1, simultaneously sound is modulated on the radio transmitter, send to the car owner, the car owner only needs the wireless receiver master cock of carrying is pushed the monitoring shelves, can hear all the tiny sound in the car vividly.
Wireless launcher is at emission monitoring signal 30-40 after second in the car, if any improper sound of movement no longer occurs, and J1 dead electricity then, the utility model just automatically restores to stand-by state.
Wireless encoding is reported to the police (not disturbing residents) and is automatically converted to the interior highly sensitive monitoring of sound of car is the most outstanding characteristics of the utility model, it is equivalent to the car owner oneself " ear " is placed in the car, in active distance (open ground 〉=600 meter), highly sensitive situation about with high fidelity monitoring in the car.
Consider the sealing situation difference of different types of automobile, and body construction difference, not equal with material, can make solid low frequency conductivity change, for this reason, vibration detector Z is connected with a variable rheostat P1, its series connection point connects amplifier input terminal.Detector has just possessed the adjustable function of detectivity like this, regulates so that carry out optimum regime at different automobile types.
More than narration and embodiment for the utility model is described, are not to be used for limiting claim of the present utility model only, and therefore, the improvement of any unsubstantiality of doing based on the utility model and prior art surely belongs within the scope of patent protection of the present utility model.
