Abstract

Theft monitoring for vehicles and / or moving objects with an infrasonic sensor (1), characterized in that the pressure sensor (1) is associated with an acceleration sensor (2).

Description

Theft monitoring for vehicles and / or moving objects with an infrasonic sensor, characterized in that the pressure sensor ( 1 ) an acceleration sensor ( 2 ) assigned.

The The present invention relates to vehicle theft surveillance and / or other moving objects with an infrasonic sensor. This pressure sensor protects doing the interior against access through doors and windows. The combination with an acceleration sensor and thus the evaluation of the inclination of the vehicle allows an additional monitoring from the outside fixed vehicle parts and / or remove the entire vehicle.

It is known to be by individual offenders or by professional gangs stealing cars or vehicles be broken up to parts such as tires, rims, radios, navigation systems, Airbags, fuel and other parts to steal.

Of the Invention is based on the object, an effective theft monitoring provide for themselves the individual monitoring of mobile objects, especially for the individual monitoring of vehicles of any kind in stationary traffic, at vehicle dealers, Marinas, Construction site facilities, truck stops and backup operations and overcomes the above problems.

to solution This object is inventively a theft monitoring of the type mentioned above, which is characterized in that the infrasound detector designed as a pressure sensor is at least an acceleration sensor assigned as a tilt switch / motion detector is.

A special feature of the used infrasonic sensor ( 1 ) is the containment of pressure events on door opening and / or glass breakage.

Another advantage of the infrasound sensor ( 1 ) consists in a special interference safety against sound waves of over 30 Hz and due to the design of the arrangement and effectiveness of the sensor throughout the vehicle interior.

modern Acceleration sensors measure the acting inertial force. A special feature is the measurement of the angle to the center of the earth by gravity in rest position.

A special feature of the acceleration sensor ( 2 ) is the precise inclination measurement and change over a predetermined period as well as the detection of vehicle movement in up to 3 axes.

On the Radio transmitter transmits this information directly to an alarm control panel or transmitted by the GSM radio module.

Especially preferred embodiments of Invention are the subclaims and will be explained in more detail with reference to the accompanying drawings, which demonstrate:

1 a combined infrasound and acceleration sensor with evaluation circuit and radio or GSM radio module in a schematic representation.

The drawing thus shows a vehicle monitoring by an infrasonic sensor ( 1 ) and an acceleration sensor ( 2 ) for the monitoring of vehicles of all kinds in stationary traffic.

The peculiarity of the invention is that an infrasonic sensor ( 1 ) with a modern accelerometer ( 2 ), which is used in particular for monitoring and securing vehicles, vehicle parts of all kinds in stationary traffic. The evaluation circuit ( 3 ) records the measured values and initiates the alarm.

The radio transmitter ( 4 ) or alternatively the GSM radio module ( 5 ) transmit the processed alarm to the receivers such as an alarm center or a mobile phone.

The Combination of surveillance the opening, Inclination, movement of the vehicle and transmission of information by radio to a radio alarm center or by a GSM radio module and the associated possible Acoustic, visual alarm is a good hedge to a possible Theft early counteract.
