Description

"SYSTEM OF ALARM FOR BLOCKING A VEHICLE AT DISTANCE AND ELECTRIC-ELECTRONIC EQUIPMENT HAVING SOUND OR LIGHT SIGNALING ACTIVATED BY RADIO FREQUENCY"

This report relates to a "system of alarm for blocking a vehicle at distance and electric-electronic equipment having sound or light signaling activated by radio frequency" and, more particularly, to a system and equipment which, by means of radio frequency signals within a specific frequency range, controls the status of a vehicle at a certain distance, thus allowing it to be blocked or unblocked, informing the user of such a status; in case of robbery, it further allows the vehicle to be immediately blocked, transmitting sound signals in case of casualty occurrence and informing its geographic location.

The now existing vehicle alarm systems, which block the vehicle electrical system and/or signalize a robbery or theft action or condition thereof, are provided with a distance blocking system that reaches a maximum radius of 20 meters or, in an optimized condition, with the aid of local repeating antennae, a maximum radius of 30,000 meters-

Such known blocking systems may be provided with a localizing system via GPS or further by means of a service telephone exchange through a computer network, controlling the transmission of signals between the vehicle and the activation device carried by the vehicle's owner-

In spite of being widely used, such conventional vehicle blocking systems and violation alarm, which are usually derived from the same technology used in the well-known "pagers", have several drawbacks, that is: poor reach of the system control signals; restrictions concerning the system operation areas and regions depending on the operation company; the non warranty of activation of the system and the non location of the vehicle after the robbery or theft.

In those cases where a GPS device is adapted to the blocking system, the vehicle can be located; however, such alternative is too costly and only justifiable in case of valuable cargo transportation fleets, thus not being feasible for personal vehicles. Another drawback of these pager-type conventional systems resides in the fact that the access between the user and the vehicle has to be carried out only by an operation company

One of the objective and advantages of the present invention is to provide a system of alarm for blocking a vehicle at distance and electric-electronic equipment having sound or light signaling activated by radio frequency, that presents a limitless reach of transmission of signal of command of the system

Another objective of the present invention consists in providing a system that provides a faster and automatic location of the vehicle, as soon as requested and after activating the blocking system of the same, seeking to hasten the recovery of the vehicle

Another objective of the present invention consists in providing an electric-electronic equipment seeking to provide additionally an unidirectional channel of conversation open selectively between the intern atmosphere of the vehicle and, at least, one external and distant point of the same, facilitating an auditive control of everything that happens inside the vehicle object of the robbery followed by kidnapping of its users These and other objectives and advantages of the present invention are reached by means of a system of alarm for blocking a vehicle at distance and electric- electronic equipment having sound or light signaling activated by radio frequency, said system comprising an electric-electronic blocking component, controlled by a radio frequency signal reception and transmission cellular component operating within the range of 824.010 to 848.970 MHz (TX) and 869.010 to 893.970 MHz (RX), said components being connected to the vehicle electrical and fuel feeding circuits, so as to immediately and simultaneously interrupt such feeding circuits when the cellular component is activated at a certain distance from any location by using a radio frequency signal generator device- The system includes the provision of an automatic central of monitoring that promotes the connection of the return radio frequency signal between the vehicle and the telephone receiver originator of the blockade, and it still detects simultaneously the location of the area that generated that return signal, guaranteeing the fast recovery of the vehicle. The equipment that defines the system consists in an electric-electronic blocking circuit board to be electrically connected to the vehicle electric and fuel injection feeding control circuits, said blocking circuit board being connected to a radio frequency signals transmission and reception cellular device which is responsible for activating and deactivating said electric-electronic blocking circuit which, in turn, is responsible for interrupting the vehicle electric and fuel feeding systems and further informing the vehicle^'s owner about the blocking activation by means of radio frequency signal returned by the system cellular device, that generates a registration in the company operator of the telephony system which will be constituted in a warranty for the insurance company of the vehicle that the system was activated and will contributes to the decrease of frauds in the casualty registration; being said equipment provided with a circuit of sound and/or visual alarm to identify the violation of the vehicle; being, still, a function of the electric-electronic blocking circuit to activate a sound and/or visual alarm circuit in order to identify the vehicle violation; the equipment still brings panic cells, constituted by small activating buttons arranged in a strategic place of the interior of the vehicle, allowing that through the user's discreet and continuous touch on those buttons, be open an unidirectional conversation channel where through radio frequency it is permitted to the automatic central listen everything that happens inside the vehicle, permitting in this way, define next steps of vehicle unauthorized occupants'.

Now, the present invention will be described with reference to the attached drawing, in which' Figure 1 shows a block diagram of said vehicle alarm system for blocking the vehicle at a certain distance;

Figures 2 and 3 represent diagrams of the circuit boards that compose the blockade equipment in subject;

Figure 4 represents the diagram of the electronic circuit that defines the blockade equipment in subject; and

Figure 5 represents a block diagram of a more sophisticated version of the vehicle alarm system for blocking the vehicle at a certain distance;

According to such illustrations, the system comprises an electric- electronic blocking component 1, controlled by a radio frequency signal reception and transmission cellular component 2 of the TDMA (Time Division Multiple Access) and CDMA (Code Division Multiple Access) types, which operates within the range of 824.010 to 848.970 MHz (TX) and 869.010 to 893.970 MHz (RX), to activate the electric-electronic blocking components 1 connected to the vehicle electrical and fuel feeding circuits 10. so as to immediately and simultaneously interrupt such feeding circuits when the cellular component 2 is activated at a certain distance from any location by the user, using any kind of radio frequency signal generator device 3 , for example, a conventional public, residential and/or business telephone.
