Method of setting and releasing lock mode of a compact disc player for a vehicle using a compact disc and a device for performing the same

The present invention relates to a security method for a compact disc player for a vehicle and an apparatus for performing the same, and more particularly, to a method for setting and releasing a lock mode of a compact disc player for a vehicle using a compact disc, and an apparatus for performing the same.

It is the desire of all human beings to listen to good music at will. Listening to music in a car can be very useful, such as relieving boredom while driving and stabilizing the driver's mind.

By 1925, radio receivers were already installed in automobiles, and the same technology was applied in automobiles in accordance with the spread of acoustic media such as home radios, tape recorders, cassette decks, and compact discs, which was developed by the phenomenal development of sound reproduction technology with semiconductor technology since the 1950s. Nowadays, the compact disc player is gradually being widely used due to its sound quality and ease of use compared to other acoustic media.

A compact disc that reproduces sound quality superior to other sound media is a disc for digital recording of music signals and image signals. The signals recorded on the compact disc are loaded into a compact disc player, and optical pickup using laser light is performed. The non-contact recorded signal is read.

Expensive car audio ranks high in stolen goods. In order to prevent theft of such a vehicle audio device, the vehicle audio itself may have a security function. This is an electronic circuit that once removed the audio device from the vehicle, will not work again unless a password is entered.

Alternatively, when the compact disc player is driven, the compact disc player is initially driven using passwords of a plurality of key combinations.

However, the above-mentioned passwords are easily forgotten by the user, and the driver who drives a borrowed vehicle for a while has the trouble of memorizing the password for driving the compact disc player, so that the vehicle is stolen or used for car audio. The original purpose of security in case a compact disc player was stolen could be a hindrance.

Accordingly, the present invention has been made to solve the above-mentioned conventional problems, and a first object of the present invention is to use a compact disc for password without using a password by a plurality of key combinations when the compact disc player is driven. An object of the present invention is to provide a method for setting a lock mode of a compact disc player.

It is also a second object of the present invention to provide a method for releasing the security of a compact disc player for a vehicle for normally driving the compact disc player by releasing the lock mode of the compact disc player set by the compact disc for password.

Further, a third object of the present invention is to provide an apparatus for performing the password setting method and the release method of the compact disc player for a vehicle.

According to the security method of a compact disc player for a vehicle using the compact disc and a device for performing the same, when setting a password of a compact disc player for a vehicle, the TOC section of the inserted compact disc is stored as a memory and used as a password. During operation, the TOC section of the compact disc inserted into the compact disc insertion slot is read at all times, compared with the stored TOC section, and if it is the same, normal compact disc player operation is performed. Allow only compact disc players to run.

Hereinafter, with reference to the accompanying drawings, it will be described in detail the present invention through an embodiment of the present invention.

Fig. 1 is a block diagram of a compact disc player for a vehicle for using a TOC section of a compact disc as a password.

Referring to FIG. 1, a compact disc player for a vehicle using the TOC section of the compact disc as a password includes a compact disc inserting unit 10, a control unit 20, a TOC reading unit 30, a nonvolatile memory 40, and a compact disc. The player driving unit 50 is configured.

The compact disc insertion unit 10 receives a compact disc from the outside and provides a compact disc insertion signal to the controller 20.

When setting the password, the control unit 20 provides the nonvolatile memory 40 with the TOC section signal read out from the inserted compact disk to set the password of the compact disc player driver 50. When the password is checked, the compact disc player driver 50 compares the TOC section signal read out from the inserted compact disc with the TOC section signal stored in the nonvolatile memory 40 in the setting step of the password. On, the compact disc drive is allowed, and in other cases, the compact disc player drive unit 50 is turned off to limit the compact disc drive.

The TOC reading unit 30 first reads a TOC section signal from every compact disc inserted into the compact disc inserting unit 10, and provides the read TOC section signal to the controller 20.

The nonvolatile memory 40 stores the read TOC section signal as a password only when a password is set.

The compact disc player driver 50 drives the compact disc in response to the control of the controller 20.

2 is a flowchart illustrating a method of setting a lock mode of a compact disc player for a vehicle according to an embodiment of the present invention.

1 and 2, power is supplied to a compact disc player for a vehicle through an operation such as inserting a key of the vehicle first, and it is checked whether a compact disc for use for a password is inserted (step S11). .

When the compact disc is inserted in step S11, the TOC section is read out from the inserted compact disc (step S13). In this case, the TOC (Table of Content) section is a section that reads first from the inserted compact disk when the compact disk player is driven, and information about various programs included in the compact disk, for example, a music compact disk, in which block Which part is recorded, and auxiliary data that can be conveniently controlled during the performance are recorded. The TOC section of such a compact disc is different for each compact disc.

Subsequently, the TOC section read in step S13 is stored in the EEPROM, which is a nonvolatile memory (step S15).

The control unit sets the compact disc player lock to the lock mode using the stored TOC section as a password to complete security of the compact car player (step S17).

3 is a flowchart illustrating an initial driving method of a compact disc player for a vehicle in which a lock mode is set according to an embodiment of the present invention.

1 to 3, first, power is supplied to a compact disc player for a vehicle through an operation such as inserting a key of a vehicle, and whether the compact disc for password is inserted through the compact disc inserting unit 10. Is checked (step S21). At this time, the compact disc player has a password set by the password setting step of the compact disc player shown in FIG.

The TOC section is read out from the compact disc inserted in step S21 (step S22).

Then, it is checked whether the lock mode is set in the compact disc player (step S23).

When the lock mode is set in the compact disc player in step S23, it is checked whether or not the TOC section read out in step S22 is identical to the initially set TOC section (step S24).

As a result of the check in step S24, if the read TOC section and the initially set TOC section are the same, the lock mode of the set compact disc player is released (step S25), and the normal operation of the compact disc player is performed (step S26). Preferably, the compact disc player will continue to operate until the input power is off.

In the step S24, when the read TOC section and the memorized TOC section are different, it is checked whether or not the inserted compact disk is replaced, and when the inserted compact disk is replaced, the process returns to the step S22 to feed back the compact disk for password. If the inserted compact disc is not replaced, the operation is terminated (step S27).

As described above, according to the present invention, the TOC section of the password disk is initially stored by the user in the nonvolatile memory, and the stored TOC section is used as a password. It is driven in response to the insertion of the password compact disc for checking the password every time.

As described above, when setting a password of a compact disc player for a vehicle according to the present invention, the TOC section of the inserted compact disc is stored as a password, and a compact disc is always inserted into the compact disc insertion slot when the compact disc player is driven. After reading the TOC section and comparing it with the memorized TOC section, if it is the same, normal compact disc player operation is performed, and if it is different, the compact disc player is allowed to be operated only by the person holding the compact disc for password. . Therefore, it is possible to perform the initial operation only if the compact disc for the password is required, without having to drive the compact disc using a memorized or recorded password, either for the tenant who owns the vehicle or the renter who rents the vehicle.

In addition, even if a stolen vehicle or a compact disc player for a vehicle is stolen, the driver may not be driven unless the compact disc for password is inserted, thereby alerting a person who is aware of it, thereby reducing the probability of theft.

Although the above has been described with reference to a preferred embodiment of the present invention, those skilled in the art will be variously modified and changed within the scope of the present invention without departing from the spirit and scope of the invention described in the claims below. I can understand that you can.
