Description

  The present invention relates to an antitheft device, and more particularly to an apparatus having a function of preventing an engine or an apparatus including an engine from being stolen.

  Currently, the use of engines and devices equipped with engines is widespread and necessary worldwide. However, since the engine and the apparatus including the engine are generally expensive, there are many cases in which the engine or the apparatus including the engine is stolen. It is not difficult for a thief who is familiar with the structure of an engine-equipped device and its operating principle to steal the engine-equipped device.

  In the case of a vehicle equipped with an engine or a vehicle, the thief breaks the ignition lock after breaking the door lock of the vehicle or illegally entering the vehicle by other means. An ignition switch can be used to start the engine by operating a starter. The thief can start the engine using the ignition switch by using the key that the vehicle owner has or a copy of it. As another method, a thief first destroys a part of an electric circuit and then connects an important electric circuit to start an engine. To prevent the car's anti-theft system or alarm system from being activated and activated, the thief can disconnect important electrical circuits such as the power line of the anti-theft system or an alarm device in the car Or throw it directly out of the car. A thief can drive and steal a car simply by successfully starting the engine and destroying other important devices such as locks and protection devices in the vehicle. Therefore, development of a device having an antitheft function has been desired.

An object of the present invention is to provide an automobile theft prevention device that effectively prevents the engine or a device including the engine from being stolen and has high safety.

In order to achieve the above-described object, the vehicle antitheft device of the present invention includes first transmission / reception means and processing means mounted in the automobile . The first transmission / reception means is connected to the engine and controls the engine. The processing means has second transmission / reception means, is connected to the first transmission / reception means via the second transmission / reception means in a wireless manner, and transmits signals to the first transmission / reception means to control the engine. The processing means performs identification using the identification code, and the user can control the processing means by using the identification code, and can further set a password. When the password is input to the processing means by the user, the user can start the engine using the processing means. Conversely, if an incorrect password is input to the processing means, the user cannot start the engine by the processing means.

Therefore, the automobile anti-theft device of the present invention can effectively prevent the engine or the device equipped with the engine from being stolen and improve safety.

As can be seen from the various ways in which the thief steals cars, one of the reasons why cars are easily stolen is that engines, starters, ignition switches and their electrical circuits and other parts are traditionally wired. This is because they are connected. Therefore, the thief can steal by driving the car and starting the engine just by successfully connecting the electric circuit. The present invention provides an automobile antitheft device that can eliminate these drawbacks.

FIG. 1 is a schematic diagram showing an automobile antitheft device according to a preferred embodiment of the present invention. As shown in FIG. 1, the automobile antitheft device is used in an automobile 100 or the like. The vehicle antitheft device includes a transmission / reception means 104 and a processing means 106. The transmission / reception means 104 is connected to the engine 102 and controls the engine 102. The engine 102 is an automobile engine (automobile engine) disposed in the automobile 100, for example. The processing means 106 and the transmission / reception means 104 are completely connected in a wireless manner, and the processing means 106 transmits a signal to the transmission / reception means 104 to control the engine 102. The processing unit 106 includes a transmission / reception unit 108, and the processing unit 106 transmits a signal to the transmission / reception unit 104 by the transmission / reception unit 108. The processing means 106 is a device having a processing function such as a computer, and controls the engine 102 with software or the like.

  The processing means 106 is identified by a predetermined identification code (ID code), and a user such as a vehicle owner controls the processing means 106 using this identification code. For example, the user can obtain the right to operate and control the processing means 106 by inputting the identification code into the processing means 106. Since each processing means of the present embodiment requires an identification code having only one authentication function, stolen items are not easily sold. The identification code described above can only be possessed by the owner, manufacturer and informed person of the processing means 106.

  The user can set a password when operating the processing means 106. Password setting includes changing the password. The password functions include those described below. When the user enters this password into the processing means 106, the user can use the processing means 106 to start the engine 102. Conversely, if an incorrect password is input to the processing means 106, the user cannot start the engine 102 by the processing means 106.

  Since there is no electrical connection line between the processing means 106, the transmission / reception means 104 and the engine 102 of the present embodiment, the thief cannot start the engine 102 by various conventional methods including the connection line method. . For example, the processing means 106 must be used to start the engine 102 because there is no prior art system such as an ignition switch and its circuit and starter. Therefore, the thief cannot start the engine 102 and drive the automobile 100 unless the password and the identification code are known. In this way, the engine 102 and the automobile 100 including the engine 102 can be prevented from being stolen. Further, the function of the processing means 106 can be designed as follows. After the wrong password is input to the processing means 106, when the engine 102 or the automobile 100 equipped with the engine 102 is moved or pulled over a certain distance, the processing means 106 sends a signal and an abnormality has occurred. Let me know. Further, when no password or identification code is input to the processing means 106, the processing means 106 transmits a signal when the engine 102 or the automobile 100 including the engine 102 is moved or pulled more than a certain distance. You may be informed that an abnormality has occurred. Also, a large memory is not necessary for the processing means 106 to achieve various functions as described above.

  It is important to store the identification code and password securely so that they cannot be leaked and disclosed to others. Therefore, the user may change the password frequently to improve safety. Also, an excellent hacker can unlock the password and use the processing means to start the engine, which is very cumbersome and steals the engine or the device with the engine. For those who just wanted to see it, it was not a practical method but a very difficult thing. In fact, the majority of those who steal an engine or engine-equipped device are not good hackers. Therefore, the anti-theft function of this embodiment is very effective.

Furthermore, the automobile antitheft device of the present embodiment may be provided with an alarm system in order to enhance safety. After an incorrect password is entered into the processing means, the alarm system may be designed to enter an activated state and send a signal to indicate that an abnormal situation has occurred. The car anti-theft device may further include a device or system (not shown) having tracking and positioning functions, and the positioning device may include a global positioning system (GPS). When various abnormal situations occur, such as when the wrong password is entered into the processing means or when no password is entered, such as when the engine is moved over a certain distance, the positioning device is activated to send a signal, This may be provided to a safety observer who is tracking the position of the engine. Further, this processing means may realize this positioning device or system by a design method using software.

  In the present invention, preferred embodiments have been disclosed as described above, but these are not intended to limit the present invention in any way, and anyone who is familiar with the technology can make various modifications within the scope and spirit of the present invention. Changes and corrections can be made. Therefore, the scope of protection of the present invention is based on the contents specified in the claims.
