Abstract

The utility model belongs to an automobile antitheft alarming device which is applied to the automobile, the motorcycle, and the electric vehicle. The automobile antitheft alarming device is characterized in that a control circuit which is arranged in a shell body comprises a power supply, an under-voltage circuit, a cipher decoding controller, a sensing controller, a voltage generator, and a cordless alarm emitter. The voltage generator is connected with an output electrode which is led out of the shell body. The utility model adopts a rolling cipher alarm system and a self-contained power supply. No noise is generated when the automobile antitheft alarming device gives an alarm. The false alarm rate is low. The effect of the noise on the environment is eliminated. The antitheft safety factor of the automobile is enhanced.

Description

The vehicle anti-theft annunciator

Affiliated field

The utility model belongs to a kind of anti-theft device for vehicle, especially a kind of vehicle anti-theft annunciator that is applied to automobile, motor bike, battery-driven car.

Background technology

Existing vehicle anti-theft annunciator is various in style, but common shortcoming is arranged: 1. alert frequency height, form noise, and influence environment; 2. the sound of annunciator is single, allows robber's robber's car of seeking loopholes easily; 3. burglar alarm causes colony's wrong report of other vehicles, rate of false alarm height easily; 4. burglar alarm is powered by storage battery, and when storage battery is cut off or voltage when low, annunciator is ineffective.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art part, provides a kind of simple in structure, and rate of false alarm is low, can effectively prevent the vehicle anti-theft annunciator that vehicle is stolen.

The purpose of this utility model is achieved in that

Control circuit in the housing is made up of power supply, under-voltage circuit, cryptogram decoding controller, sensing controler, voltage generator, radio alarming projector, and voltage generator connects the output electrode of drawing housing.

The utility model can also take following measure to realize:

The connection of control circuit is such: the power supply that is connected with under-voltage circuit provides electric power to cryptogram decoding controller, sensing controler, voltage generator, radio alarming projector, start anti-theft alarm behind the code signal that the cryptogram decoding controller is accepted to import, and signal delivered to sensing controler, sensing controler can be reported to the police by the radio alarming projector, simultaneously, the trigger voltage producer is prepared to the output electrode output voltage; Described sensing controler is vibration sensor or infrared pickoff, also can be both combinations; Power supply telltale, under-voltage telltale show on housing; Described cryptogram decoding controller is 9916 type superregeneration rolling code receiver modules, and the vibration sensor of described sensing controler is the DN-3 vibration sensor, and infrared pickoff is a TS05C type infrared pickoff; Described voltage generator is a DF888D pulse safety voltage module; Described radio alarming projector is the 9916 type superregeneration rolling code transmitter modules that are complementary with the cryptogram decoding controller.

Advantage of the present utility model and good effect are:

1. do not have the sound when reporting to the police, just driver's remote control equipment (RCE) produces action, and noise does not take place, and has eliminated the influence of NOISE ON ENVIRONMENT;

2. owing to adopted special vibration sensor or infrared pickoff, have only the robber when promoting or start vehicle, anti-theft measure just starts, so rate of false alarm is very low, does not also influence the wrong report of other vehicles.

3. adopt the electrode of voltage generator to be installed in bearing circle or trick contact position, the safety voltage of generation is warned the robber, improves the theftproof performance of vehicle,

4. adopt rolling cipher alarming system and power autonomous, prevented that the robber from arbitrarily cutting off the electricity supply and make the phenomenon of vehicle loses warning function, improved the anti-theft security coefficient.

Description of drawings

Fig. 2 is a circuit block diagram of the present utility model;

Fig. 3 is the circuit diagram of under-voltage circuit of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is further described:

The utility model is made of housing 1 and interior control circuit thereof, and power supply telltale 2, under-voltage telltale 3, output electrode 4 and power lead 5 also are installed on housing.Control circuit in the housing is made of several parts such as power supply E, under-voltage circuit, cryptogram decoding controller, sensing controler, voltage generator, radio alarming projectors, wherein power supply is for providing for oneself and chargeable direct supply, can adopt the storage battery of 6 volts or 12 volts, power supply is shown at the power supply telltale D1 on the housing (label on the housing is 2) when work.

In the circuit diagram of under-voltage circuit (referring to Fig. 3), power supply E provide electric power, three aerotron BG1, BG2, BG3 interconnect successively, resistance R 1, R2 are divider resistance, R3, R4 are load resistor, R5 is a current-limiting resistance, shows undervoltage condition with the series connected light-emitting diode D2 of R5 (label on the housing is 3) and shows on housing.

The cryptogram decoding controller is that 9916 commercially available type superregeneration rolling codes are accepted module, buys with car owner's remote controller coupling and uses, because be prior art, present embodiment is no longer narrated.

Sensing controler can be vibration sensor, infrared pickoff or the combination of the two, and what vibration sensor adopted is commercially available DN-3 vibration sensor; Infrared pickoff adopts the infrared correlation sensor of TS05C, because these two sensors are prior art, present embodiment is no longer narrated.

The wireless anti-theft projector is the product that the remote controller with cryptogram decoding controller, car owner is complementary, and its effect is that signal is issued the car owner, is existing commercially available prod, is 9916 type superregeneration rolling code transmitter modules.Because be prior art, present embodiment is no longer narrated.

Voltage generator is commercially available DF888D pulse safety voltage module, and what send is safety voltage, can not work the mischief to human body.Because be prior art, present embodiment is no longer narrated.

Output electrode adopts metal filament or metal contact, is installed in the contact site of people on bearing circle or the car.
