Abstract
The utility model relates to a safety alarm for a motor vehicle. The utility model can indicate whether the motor vehicle is stolen and hijacked or not. A detector, a weak signal amplifier and a shaping circuit trigger are connected with a power-cut controller, a coding circuit, a frequency modulation emitter, a language slice and a power amplifier in turn. A hijacking alarm button and a square wave generator are connected with the power-cut controller. The detector is electrically connected with one end of the weak signal amplifier, and the other end of the weak signal amplifier is electrically connected with the shaping circuit. The other end of the shaping circuit is electrically connected with a trigger, and the other end of the trigger is electrically connected with the power-cut controller, the coding circuit, the frequency modulation emitter, the language slice and the power amplifier.
Description
The utility model relates to a kind of motor vehicle safety warning device that the vehicle chance is stolen and vehicle is held as a hostage of indicating, especially can allow not driver at the scene know that in time vehicle is just stolen, can allow the driver when vehicle is held as a hostage, secret is outwards sent light warning, and the greeting colleague and the masses arrest the offender.
At present, known vehicle alarm device is that door contact interrupter triggers, and sounds and reports to the police or while point of cutoff ignition source.Since vehicle newness degree difference, the working environment difference, and car door is opened in contact good inadequately, causes wrong report easily, even can't normal row.In addition, if the driver does not have the masses at the scene again, often do not have effect even send warning yet.On the other hand,, be the easily passive people of holding like this and find though existing independent abduction warning device is taked left alone without help car measure more, unfavorable to driver's safety.
The purpose of this utility model is to provide a kind of vehicle safety annunciator, and it can not only accurately be judged has the people attempting illegal driving engine motor vehicle, and can give full play to driver and the masses and the common protection vehicle of going together on every side, and sound is rescued the driver and arrested the offender.
The purpose of this utility model is achieved in that detector, weak item amplifier, shaping circuit, binary pair and circuit breaking controller, encode circuit, frequency-modulated transmitter, language sheet, power amplifier are linked in sequence; Kidnapping alarm button, square-wave generator and circuit breaking controller is linked in sequence.Detector is electrically connected with weak signal amplifier one end, the weak signal amplifier other end is connected with shaping circuit, the other end of shaping circuit is electrically connected with binary pair, and the binary pair other end is electrically connected with circuit breaking controller, encode circuit, frequency-modulated transmitter, language sheet, power amplifier.Encode circuit, frequency-modulated transmitter and language sheet power amplifier be arranged in parallel.Kidnapping alarm button and antitheft start button be arranged in parallel.Detector, weak signal amplifier, comparator, shaping circuit, binary pair, MOS switching sequence connect.When the human body infrared probe that makes produces AC signal after the weak signal amplifier amplifies, the comparator output low level is sent this vehicle code signal through shaping circuit and 0.5 second rear drive annunciator of the monostable time-delay of binary pair frequency modulation again, circuit breaking controller point of cutoff fire coil, make vehicle not start and to be stolen, driver's abduction alarm button that closes when being held as a hostage as vehicle, square-wave generator gets electric work, make the work of high-tension coil interruption, vehicle can not cruising, to stall for time, provide condition for the driver gets away and arrests criminal, make also that vehicle is unlikely to be stolen.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is schematic circuit diagram of the present utility model.
