The present invention relates to a vehicle theft alarm system and theft alarm method using Etax, when it is determined that the current vehicle is a stolen state by using the stolen vehicle data newly received from the outside while Etax is stored in the memory or started on. The present invention relates to a vehicle theft alarm system and theft alarm method using ETAX to automatically solve the theft event by wireless transmission of the burglar alarm signal.

Recently, there has been increasing interest in preventing theft of vehicles, and particularly, devices for preventing theft have been installed essentially in medium and large vehicles.

In general, when an anti-theft signal is set on a vehicle body, an electronic time and alarm control system (ETACS), which is a system for controlling time and an alarm system, is provided with a siren or horn installed in a vehicle. horn lights to warn.

However, in the anti-theft device of the vehicle informing that the situation is stolen by operating the siren or the horn, the vehicle can be easily stolen if only a part of the basic device is dismantled (such as cutting the siren or the horn wire).

In other words, if a driver is forced to escape after dismantling a siren or a horn that informs theft of the outside, theft of the vehicle is increasing day by day.

On the other hand, conventional systems do not have systematic measures for fast arrest and collection of vehicles in the event of theft of the vehicle, and the police can rely on search / search even if a stolen vehicle occurs and the owner reports. There was only.

In other words, because there was no way to inform the system that the vehicle was stolen, the police had no choice but to rely on the license plate. When the license plate was changed, it was necessary to search the vehicle number.

Therefore, a lot of time and manpower was wasted to find a stolen vehicle, and the recovery rate of the stolen vehicle was also very low. Therefore, measures to cope with this situation are urgently required.

Accordingly, the present invention has been invented to solve the above problems, theft alarm when it is determined that the current vehicle is a stolen state by using the stolen vehicle data newly received from the outside while the etax is stored in the memory or started on It is an object of the present invention to provide a vehicle theft alarming system and theft alarming method using ETAX to automatically solve the signal theft by wireless transmission.

Hereinafter, with reference to the accompanying drawings will be described in more detail the theft alarm system and theft alarm method according to the present invention.

The present invention is a theft notification system that is installed in a conventional vehicle to improve the function of the Etax by adding a wireless transmission / reception module to the Etax (ETACS: Electric Time and Alarm Control System) system that controls the time and alarm device In addition, the stolen vehicle data may be determined using the stolen vehicle data that is stored or newly received in the on state, and if the stolen situation is determined, the vehicle may output the stolen notification signal of the vehicle.

Of course, it is obvious that a separate notification system can be configured without using Etax.

However, in the case of configuring the notification system including a separate control unit not including the etax, the function may be disabled when the notification system is recognized by the vehicle thief, so that the etax and the absolutely necessary for the operation of the vehicle It is desirable to prevent such functional impairment by including the same electronic control device.

1 is a schematic installation state diagram of a notification system according to the present invention, Figure 2 is a block diagram showing the configuration and connection of the notification system according to the present invention.

As described above, the Etax 40 is mounted on the vehicle 10 and performs various functions such as operation of a power window, door locking, taillight off, theft alarm, and the like. ) And a receiving module 44 is further added.

The transmission module 42 outputs the burglar notification signal of the vehicle, and the reception module 44 is for receiving a signal including the burglar vehicle data from the outside.

The transmitting module 42 and the receiving module 44 may be built in the etax 40 or may be connected to be manufactured as a separate module.

In addition, a separate transmission / reception antenna 20 is mounted on the vehicle 10 for wireless communication of the transmission module 42 and the reception module 44.

The vehicle transmit / receive antenna 20 receives a radio signal including the stolen vehicle data from the police transmit / receive antenna 50 to be described later and inputs the received signal to the receiving module 44, and outputs the burglar notification signal output from the transmitting module 42. It is responsible for wireless transmission to the outside.

Further, reference numeral 30 denotes a radio and reference numeral 36 denotes a radio antenna, which are also mounted on the vehicle 10.

In the present invention, the radio 30 may be further configured to receive a radio wave including the stolen vehicle data from the base station (not shown) of the police station through the radio antenna 36, wherein the radio 30 is a radio antenna ( It is configured to extract the data component from the radio wave received through 36 to be transmitted to the Etax 40.

That is, the radio 30 continuously receives a signal of a specific frequency band and extracts a data component of the radio wave and transmits the data component to the Etax 40. For this purpose, the stolen vehicle is received from the received radio wave of the specific frequency band. It has a data extraction section 32 for extracting data, and a data transmission section 34 for transmitting the extracted stolen vehicle data to the etax 40.

here. The radio wave uses a radio wave having a specific frequency band of the unused band, and the reason for using the radio wave of the unused band is that the police transmitting / receiving antenna 50 which will be described later by transmitting radio waves of the unused band nationwide and always propagating signals. This is to allow the vehicle to receive stolen vehicle data even in areas not installed.

In such a configuration, Etax receives two signals.

The first is the stolen vehicle data received by the vehicle transmit / receive antenna 20 from the police transmit / receive antenna 50 to be described later, and enter the transmission module 42. The other is received by the radio antenna 36 and extracted from the radio 30. Stolen vehicle data.

The Etax 40 compares the data with pre-stored inherent information of the own vehicle and determines the stolen notification signal of the vehicle through the transmission module 42 and the transmission / reception antenna 20 when the vehicle is stolen. Perform the operation of transmitting.

On the other hand, the police transmitting and receiving antenna 50 is installed in the vicinity of the highway or frequent traffic, it is possible to continuously transmit a signal containing the stolen vehicle data to the passing vehicle by wireless, and also the stolen recognized vehicle Transmission data, that is, a burglar notification signal propagated from the transmission / reception antenna 20 of the vehicle can be wirelessly received.

For the present invention, a plurality of police transmitting / receiving antennas 50 having their own transmitting / receiving modules should be installed, and each of the present location of the vehicle is directly connected to the police station when theft notification signal of the stolen vehicle is received. The data can be notified to the police.

Next, the mobile receiver 52 also preferably receives the transmission data of the stolen vehicle, i.e. the theft notification signal, within its reception range with its own antenna, which the police officer may personally receive. It may be a portable receiver 52a that can be carried with a vehicle or a vehicle receiver 52b mounted in a police car.

That is, in addition to receiving a signal through the police transmission and reception antenna 50, a police officer with a nearby police car or a portable receiver 52a receives a burglar notification signal that is continuously generated / sent from the stolen vehicle, and thus has It is to make it easy to recognize the location, and to use it for theft arrest and recovery of stolen vehicles.

In the present invention, the stolen vehicle data of the signal propagated through the police transmission and reception antenna 50 are unique identification information of the stolen and received vehicle including a vehicle number, an engine or a vehicle number, and the like. The data of the burglar notification signal transmitted from 20) is information including the vehicle number.

On the other hand, although not shown in detail, in order to ensure that the notification system of the present invention is always operated even in a parked state, the power source is preferably used a battery, wherein the battery is a rechargeable battery that can be charged by the power generated when driving the vehicle Use

For example, Etax can be configured to send a burglar alarm even if the ignition key is not plugged in and the battery power is applied to determine that the car is a stolen vehicle. Help the police know it's a stolen vehicle.

3 is a state diagram of a notification system according to the present invention, in which a plurality of police transmitting / receiving antennas 50 installed around a road continuously propagate a radio signal including the stolen vehicle data, and recognize the stolen vehicle ( 10) receives a burglar notification signal including a vehicle number.

The driving vehicle 10 continuously receives a radio signal including the stolen vehicle data from the police transmitting / receiving antenna 50 within the receiving range through the vehicle transmitting / receiving antenna 20 and also radio waves containing the stolen vehicle data. Is received via the radio antenna 36.

The etax (not shown in FIG. 3) of the vehicle 10 compares the recognized stolen vehicle data with previously stored data, and if it is matched, recognizes theft as a stolen state and receives a burglar notification signal including the vehicle number within the reception range. Transmitting to the police transmission and reception antenna 50 or a mobile receiver (vehicle receiver and portable receiver).

In addition, the police car 10a through the vehicle receiver (not shown 52b in FIG. 2, not shown in FIG. 3), the police officer theft notification signal propagated from the vehicle 10 recognized stolen through the portable receiver 52a Received to check the presence and location of the stolen vehicle around.

Hereinafter, a notification method performed in the notification system of the present invention will be described with reference to the flowchart of FIG. 4.

The control module (not shown) built in the Etax 40 in the state where the power is applied generates the theft alarm signal when the theft state data is stored in the memory.

That is, the control module in the Etax 40 reads the vehicle number data pre-stored in the memory and transfers it to the transmission module 42. The transmission module 42 modulates the received vehicle number through the antenna. Send it out.

The transmitted radio modulation signal is propagated to the air, and thus the radio modulation signal transmitted from the transmission module 42 includes a signal indicating that the signal is a burglar notification signal including a vehicle number, thereby preventing crosstalk with other signals. do.

The transmission of the theft notification signal is continued until the release signal is input. In particular, the release signal is input in the form of an encryption code from a separate release device (not shown), and when the release signal is input, the release signal is stored in the memory. All theft data is deleted.

The burglar notification signal transmitted as described above is received by the police station transmitting and receiving antenna 50 in the reception range around the stolen vehicle and notified to the police station, or received by the mobile receiver 52 of the police car and police officers.

As a result, the police station can identify the police transmitting and receiving antenna (50) that has been informed of the theft alarm signal to determine that there is a stolen vehicle whose vehicle number is identified at a short distance, and the patrol police car or police officer is stolen along with the vehicle number. It can be recognized that the vehicle is located.

On the other hand, if the start-up (on) after the power is applied, the control module in the Etax 40 is a wireless including the stolen vehicle data through the separately installed transmitting and receiving antenna 20 or the radio antenna 36 mounted You will receive a signal.

Here, the radio signal including the stolen vehicle data is propagated from the police transmitting and receiving antenna 50, the stolen vehicle data includes identifiable unique information of the stolen vehicle reported theft at the police station.

When the radio signal including the stolen vehicle data is received from the police transmission / reception antenna 50 by the vehicle transmission / reception antenna 20 as described above, the received radio signal is demodulated by the reception module 44 in the etax and stolen. Vehicle data is recognized by the control module of the etax 40.

Alternatively, when a radio wave including the stolen vehicle data is received from the base station of the police station by the radio antenna 36 of the vehicle, the received radio signal is extracted by the data extracting unit 32 in the radio, and this extraction is performed. The stolen vehicle data is transmitted to the control module of the Etax 40 by the data transmission unit 34, and eventually the stolen vehicle data is recognized by the control module of the Etax 40.

The Etax 40 compares the recognized stolen vehicle data with pre-stored unique information of the own vehicle, and determines whether the stolen vehicle is stolen. When it is determined that the own vehicle is the stolen vehicle, the etax 40 stores the stolen state data in the memory and simultaneously the theft alarm signal Generates.

That is, the control module in the Etax 40 reads the vehicle number data stored in advance in the memory and transfers it to the transmission module 42, and modulates the vehicle number received by the transmission module 42 through the antenna. It will be sent continuously.

Of course, the burglar notification signal is received by the police transmitting and receiving antenna 50 in a state in which the stolen vehicle enters the reception range and notified to the police station, or is received by the mobile receiver 52 of the police car and police officer within the reception range.

Once the Etax 40 determines that the vehicle is a stolen vehicle and stores the stolen state data, the Etax 40 in the standby state until the separate release signal is input even after starting off. ) Continuously transmits the burglar notification signal, and the transmission of the burglar notification signal can be stopped only when the release signal is input and the theft state data is deleted.

In this way, in the present invention, it is possible to determine whether the current vehicle is theft situation by using the stolen vehicle data newly stored in the memory or in the start-up state, and theft situation is determined as theft situation. In this case, the theft alarm signal of the vehicle may be transmitted, and the police having received the theft alarm signal may easily recover the stolen vehicle by tracking the location of the stolen vehicle.

As described above, according to the present invention, when it is determined that the current vehicle is stolen by using the stolen vehicle data that is stored in the memory in the standby state or newly received from the outside in the startup on state, the vehicle is notified of theft. By transmitting the signal automatically wirelessly, the police who have received the theft notification signal can quickly and easily collect the vehicle and arrest the thief, thereby reducing the consumption of human and time resources required for the vehicle recovery. Will be.
