Abstract

Disclosed is a wireless networking anti-robbery alarm device for motor vehicle, including a twelve V[DC] automotive storage battery power supply, a language chip with recording and playing, a wireless speech modulation module, a language demodulating receiving module, an audio frequency amplifier module, an automatic warning drive module as well as a moveable alarming transfer switch. The device can be set up into transmitting state or receiving state through an implicit transfer switch, the device is set up into receiving state under normal conditions. The production is a wireless network alarming device which is composed of the motor vehicle, once a motor vehicle is robbed, the implicit mobile switch of the vehicle robbed can be immediately pushed, the vehicle type, vehicle number and the speech signal of robbery situation which are recorded beforehand are modulated to wireless carrier frequency signal and transmitted to all motor vehicles which are in the range of three hundred to five hundred meters apart from the motor vehicle robbed, immediate alarming and mutual-assistance can be implemented for preventing malignant events from happening, the utility has advantages of fast alarm response, simple structure and accurate detection.

Description

The anti-misfortune of motor vehicle radio networking robbed warning device

Technical field: the utility model relates to anti-misfortune of a kind of motor vehicle radio networking and robs warning device, and the wireless network that this device is made up of self-propelled vehicle self is realized reporting to the police.

Background technology: existing self-propelled vehicle warning device adopts vibration sensor to report to the police mostly, owing to its structural reason remote control distance is near, also can produce wrong report sometimes, the purpose that out of reach is reported to the police, and do not have the anti-function of plundering,

Summary of the invention: the purpose of this utility model is at above-mentioned the deficiencies in the prior art, and a kind of self-propelled vehicle of can realizing is provided, and particularly anti-misfortune of the Wireless Networking of taxicar Rapid Alarm robbed warning device.For achieving the above object, the utility model adopts following technical proposals: the anti-misfortune of motor vehicle radio networking robbed warning device, comprise 12VDC automobile storage battery power supply (1), but it also comprises recording playback language chip (2), wireless sound modulation module (3), wireless sound demodulate reception module (4), audio frequency amplification module (5), auto alarm driver module (6) and removable warning change-over swith (7).This device can be set into emission state or receiving condition by implicit conversion switch (7), all is configured to receive state under the normality.

Motor vehicle radio described in the utility model networking is anti-robs to rob and rescue warning device mutually with existing self-propelled vehicle annunciator relatively has following characteristics: it is rapid 1, to report to the police, timely to event handling.2, simple in structure, cost is low.3, the simple and easy practical wrong report of not having.4, the mobile wireless network of being made up of power actuated vehicle, cost is low, easy to use and maintenance.

Description of drawings:

Fig. 1 is a block diagram of the present utility model.

Fig. 2 is schematic circuit diagram of the present utility model.

Fig. 3 is the Automatic alarm telephone schematic circuit diagram.

The specific embodiment:

With reference to Fig. 1, the anti-misfortune of motor vehicle radio networking robbed warning device, comprise 12VDC automobile storage battery power supply 1, but it also comprises recording playback language chip 2, wireless sound modulation module 3, wireless sound demodulate reception module 4, audio frequency amplification module 5, auto alarm driver module 6 and removable warning change-over swith 7.This device can be arranged to emission state or receiving condition with it by implicit conversion switch 7, all is configured to receive state under the normality.

With reference to Fig. 2, the positive pole of storage battery 1 links to each other the ground terminal of negative pole connection circuit with the middle angle N that implicit expression moves transposition switch 7.But the RE of recording playback language chip 2 (ISD1006) is a record button, and PL is a play button, and MIC is for recording microphone.The positive power source terminal of chip 2 links to each other with the B angle end that implicit expression moves transposition switch 7, and out is the voice signal mouth, links to each other with the pin 4 of frequency modulation transmitter module 3 (TJL80), and the pin 1 of frequency modulation transmitter module 3 connects positive source, and pin 2 connects the negative pole of power supply, and antenna is penetrated in pin 3 sending and receiving.The pin 3 of wireless demodulation receiver module 4 (RJL81) connects antenna, and pin 1,2 connects the positive and negative terminal of power supply respectively, and pin 4 is mouths of audio language signal, links to each other with pin 2 ends of audio amplifier 5 (LM386) by 0.1 electric capacity.The pin 1 of audio amplifier 5 connects positive supply, and pin 4 connects negative supply, pin 5 audio signal output end for having amplified, and this signal drives the loudspeaker pronunciation by capacitor C 2.The other end of sound signal meets two rectifier tube D1, D2 by resistance R, and the direct current signal of output drives the base stage of aerotron after capacitor C 3 smoothing processing, make the relay J adhesive, drives the telephone automatic alarm circuit shown in Fig. 3.

With reference to Fig. 3, this device can be located at the gangway in city, and fixed installation, can be by common big field, the city wireless alarming network of forming of the radio alarming device on the self-propelled vehicle.The wireless-modulated receiver module is modulated into sound signal by antenna N with the voice CF signal, from pin 4 outputs of module, by capacitor C 1, amplify through the audio frequency amplification module, through speed-up capacitor C2, sounded by loud speaker, this sound comprises vehicle, license number and self-propelled vehicle code etc.Receiving vehicle can hear immediately, another road signal can pass through resistance R simultaneously, through diode D1, D2 rectification, through filtering capacitor C 2 signal smoothing is being handled, form direct current, drive the base stage of aerotron V, make its relay J adhesive, to be in the phone repeat key closure of hands-free state, this moment, audio alert can be reported to the police to public security department by phone.

The wireless network that this product is made up of self-propelled vehicle self is reported to the police, in case a certain self-propelled vehicle hijacking takes place, the vehicle of being robbed is pressed implicit expression immediately and is moved switch, vehicle, the license number that vehicle is recorded in advance, the voice signal of the situation of being robbed are modulated into the radio carrier frequency signal and reach all power actuated vehicles in 300-500 rice scope with it, it is reported to the police and rescue mutually immediately, prevent that malignant event from taking place.
