Abstract

A car alarm device which can give an alarm to the car owner includes a sensor arranged on the car, the sensor is connected with a switch and an A/D switching circuit, the A/D switching circuit switches analog signals sent by the sensor into digital signals and then sends to a language storing chip, and an emitter emits alarm signals which are received by a receiver pre-arranged out of the car. In order to protect the car better, the car alarm device uses the emitter and the receiver, alarm signals are emitted to the preset receiver for giving an alarm to the car owner, so as to avoiding loss by early processing.

Description

Can be to the car alarm device of car owner's warning

[technical field]:

The utility model belongs to the burglar alarm technical field, particularly a kind of alarming device for automobile anti-theft.

[background technology]:

At present, general common car alarm mostly is (interlock of car door central controlled lock) alert acoustic alarm, because the vehicle of parking in the parking lot is more, when vehicle meets situation, difficult resolution of car owner is that a situation arises for which car, therefore be unfavorable for that the car owner in time finds the generation of stolen situation, also give the thief opportunity simultaneously.

[summary of the invention]:

The utility model purpose is to solve the problem that existing auto alarm device can not be reported to the police to the car owner targetedly, and a kind of car alarm device that can report to the police to the car owner is provided.

What the utility model provided can be to the car alarm device of car owner's warning, comprise the sensor that is installed on the automobile, this sensor connects switch and A/D change-over circuit, the analog signal conversion that this A/D change-over circuit is sent into sensor is to send into the language storage chip after the digital signal, through transmitter alerting signal is sent again, and received by defaulting in the outer receiver of automobile.

Advantage of the present invention and good effect:

The utility model has used to transmit and receive setting on device in order better car to be protected, and alerting signal is transmitted into the predefined receiver of car owner reports to the police, and the car owner is in time known, early deals with and avoids loss.

[description of drawings]:

Fig. 1 is can be to the car alarm device theory diagram of car owner's warning;

Fig. 2 is sensing and an amplifying circuit schematic diagram for reference;

Fig. 3 is an A/D change-over circuit schematic diagram;

Fig. 4 is a radiating circuit schematic diagram for reference;

Fig. 5 is a receiving circuit schematic diagram for reference.

[embodiment]:

Embodiment 1:

As shown in Figure 1, what the utility model provided can be to the car alarm device of car owner's warning, comprise the sensor that is installed on the automobile, this sensor connects switch and A/D change-over circuit, the analog signal conversion that this A/D change-over circuit is sent into sensor is to send into the language storage chip after the digital signal, through transmitter alerting signal is sent again, and received by defaulting in the outer receiver of automobile.

Sensor can be a pressure transducer, the pressure transducer that is installed on when arrangements for automotive doors is opened on the car door sends by transmitter (referring to Fig. 4) pressure change signal behind A/D change-over circuit, language storage chip with alerting signal, and receives by defaulting in the outer receiver (referring to Fig. 5) of automobile.The signal of pressure transducer collection is sent into A/D change-over circuit (referring to Fig. 3) after can amplifying through amplifying circuit shown in Figure 2 earlier again.

Sensor can also be a sound transducer, and the broken sound of glass is sent alerting signal by transmitter (referring to Fig. 4) behind A/D change-over circuit, language storage chip by sound transducer, and receives by defaulting in the outer receiver (referring to Fig. 5) of automobile.

Claims

1, a kind of car alarm device that can report to the police to the car owner, it is characterized in that this device comprises the sensor that is installed on the automobile, this sensor connects switch and A/D change-over circuit, the analog signal conversion that this A/D change-over circuit is sent into sensor is to send into the language storage chip after the digital signal, through transmitter alerting signal is sent again, and received by defaulting in the outer receiver of automobile.
