Description

Error diagnostic display of the optical disc player

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical disc player, and more particularly, to an error diagnosis display device for an optical disc player that displays a cause of an error that occurs when a system is operated by a user.

Recently, electronic products provide various and convenient functions to meet the needs of users, and CD players and video CD players are also steadily evolving to deliver high quality voice and high quality images to users.

1 shows a vehicle CD player, when a user plays a CD of the audio system 30, the CD changer 10 operates according to a command applied from the audio system 30 through the transmission table 20, The data transmitted from the CD changer 10 through the transmission cable 20 is output through a reproduction process through the audio system 30. If a problem occurs in the internal circuit during CD operation, the audio system 30 displays CD Err on the liquid crystal display 36 to notify the user that CD playback is disabled. However, by looking at this, the user cannot recognize the exact cause of the error, whether the reason for non-reproducibility is due to a malfunction of the internal circuit or the user's carelessness. The damage is even worse.

SUMMARY OF THE INVENTION An object of the present invention is to provide an error diagnosis display apparatus for an optical disc player that can improve the reliability of a product by informing a user of accurate information about the cause of an error of an internal device in order to solve the problems of the prior art as described above. It is.

In order to achieve the above object, the apparatus of the present invention includes a memory in which an impossible code for error and voice data are stored; A voice controller for selectively outputting voice data among data stored in the memory; A code control unit for selectively outputting a disable code among data stored in the memory; And generating a control signal for switching to an error generation mode when an error of an internal circuit occurs to the voice control unit and the code control unit, transmitting voice data output from the voice control unit to a speaker, and outputting an impossible code output from the code control unit to the liquid crystal display unit. And a system controller for controlling the system to display.

1 is a view showing a vehicular CD player according to the prior art.

Fig. 2 is a diagram of a vehicular CD player, showing one embodiment of an error diagnostic display device of an optical disc player according to the present invention;

Hereinafter, with reference to the accompanying drawings will be described in detail the present invention.

3 is a circuit block diagram of a CD player for a vehicle according to an exemplary embodiment of the present invention, which includes a key input unit 121 for receiving a key command signal, a memory for storing disable codes and audio data relating to an error generated during CD playback. 125, a voice controller 124 for selectively outputting voice data among data stored in the memory 125, and a code controller 123 for selectively outputting an impossible code among data stored in the memory 125. And generating a control signal to the voice controller 124 and the code controller 123 to switch to the error generation mode when an error occurs and transmitting the voice data output from the voice controller 124 to the speaker 127. An audio system 120 having a system control unit 122 for controlling the system to display the disable code output from the control unit 123 on the liquid crystal display unit 126; The CD changer 100 operates in response to a command signal input to the key input unit 121 of the audio system 120 and the control command signal of the system controller 122 in the audio system 120. And a transmission cable 110 for transmitting the data output from the CD changer 100 to the audio system 120.

If the CD player according to the present invention configured as described above does not operate normally during a specific internal circuit, the audio system 120 generates a control command signal for switching from the normal mode to the error generation mode through the system controller 122. do. In response to the control command signal, the code control unit 123 and the voice control unit 124 decode the corresponding disable code and the related voice data among the error information data stored in the memory. The code controller 123 and the voice controller 124 transmit the decoded disable code and the voice data to the liquid crystal display 126 and the speaker 127, respectively. Accordingly, as shown in FIG. 2, the audio system 30 displays the disabled code divided into the large category (00) and the small category (02), such as “Er 00.02”, on the liquid crystal display 36 as shown in FIG. Find a manual on your computer so that you can easily identify the cause of the error and prescribe it. And, if the user wants a simple information about the disabled code immediately without looking for the manual, the audio system 30 outputs the cause of the error and the prescription contents through the speaker 127 as a voice.

Therefore, the present invention does not only notify the user of the error occurred during CD operation as in the prior art, but also allows the user to recognize whether the system failure or abnormality is due to a malfunction of the internal circuit or the user's carelessness. Disable code and voice information are provided.

The present invention can improve the reliability of the product by accurately notifying the user of the cause even if a system failure or abnormal condition occurs.

Claims (1)

A memory in which disabled codes and voice data relating to errors are stored; A voice controller for selectively outputting voice data among data stored in the memory; A code control unit for selectively outputting a disable code among data stored in the memory; And When an error of an internal circuit occurs, a control signal for switching to an error generation mode is generated to the voice control unit and the code control unit, and the voice data output from the voice control unit is transmitted to the speaker, and the disable code output from the code control unit is displayed on the liquid crystal display. And a system controller for controlling the system so as to control the system.
