Description

VSI / Remote control unit with troubleshooting function

The present invention relates to a VSI / remote control device having a failure diagnosis function. In particular, when a user presses a VSI diagnostic key on a remote controller, the VISA / remote control device automatically executes a self-diagnosis on the VSI set and displays the result on the LCD display of the remote controller. In this case, after-sales service can be made more convenient in the event of a breakdown of VSI set.

The basic functions of VSI can be divided into video and audio signal playback function recorded on video tape, and recording function to record broadcast signal input from outside or tuned by tuner on video tape. In particular, in order to enable reservation recording, tuning of a broadcast program by a built-in tuner and a signal processing function thereof are provided. By using the reservation recording function of VSI, accurate reservation recording of a desired television broadcast program can be executed even when not in use.

On the other hand, an important part of the VSI set having such a function, for example, if the deck portion, the capstan portion or the video signal processing unit is broken, the above functions cannot be performed. Therefore, the user calls A / S agent if the VSI set is not working well, and the A / S agent who received the request for troubleshooting needs to input the code value for the important part by using VSI's OSD function. The set side self-diagnosis is performed.

However, in the case of self-diagnosis of the VSI set as in the prior art, the self diagnosis was difficult in the VSI set without the OSD function, and the A / S agent coded an important part of the VSI set even though the OSD function was provided. There was a hassle to enter and work cumbersome one by one.

Therefore, in order to solve the above problems, when the user presses the VSI diagnostic key on the remote control, the VSD set is automatically displayed on the LCD display of the remote control after executing the self diagnosis for the VSI set. The purpose of the present invention is to provide a VSI / remote control device having a troubleshooting function that allows after-sales service personnel to make after-sales service more convenient.

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

1 is a system block diagram showing a VIAL / remote control apparatus having a fault diagnosis function according to the present invention.

In other words, the system inputs a key input unit 11 having a VSI self-diagnosis key, a memo key, a reset key and various function keys, and a code value corresponding to the self-diagnostic key of the key input unit 11 when the key input unit 11 is input. A remote control microcomputer 12 for controlling to output a control signal and taking notes of the received self-diagnosis data, and a remote control transmitter for transmitting various function command signals to a VSI set by receiving a control signal of the remote control microcomputer 12 ( 13), a remote control receiver 14 receiving the control signal of the microcomputer 12 and receiving the self-diagnosis result data from the VSI set side, and receiving the control signal of the microcomputer 12 to display the self-diagnosis result. LCD display unit 15 and a remote control device unit 10 is composed of a memory unit 16 for storing the self-diagnosis result data by receiving the control signal of the microcomputer 12 when the user inputs the memo key.

On the other hand, the VSI set side receiving unit 21 which receives the BSI self-diagnosis command signal from the transmitting unit 13 of the remote control device unit 10, and the VSI diagnosis command signal from the receiving unit 21; A VMS microcomputer 22 for controlling self-diagnosis execution and a drum speed / phase sensor unit 23 for diagnosing the operation of the deck drum of the VSI set 20 by receiving the control signal of the microcomputer 22. ), A sensing means (29) having a capstan motor speed sensor section (25) for diagnosing the operation of the capstan motor, start / end sensor sections (27, 26) and a reel sensor section (28) for sensing the start and end of a video tape. ) And a VSI set unit 20 including a VSAL set-side transmitter 30 for transmitting the diagnosis result data by the sensing means 29 to the receiver 21 side of the remote controller device 10. .

Referring to one embodiment of the present invention having the above configuration in more detail as follows.

As shown in the flowchart of FIG. 2, when the user presses the power key of the remote control key input unit 11 and sequentially presses the VSIAL self-diagnosis key, the remote control micom 12 first determines whether the power key is on or not (step). If it is determined that the device is turned on, it is determined whether the VSIAL self-diagnosis key is input (step 101).

At this time, if it is determined that the VISA self-diagnosis key is input, the V-SIAL self-diagnosis command is coded to send a control signal according to the transmitter 13, and accordingly, the transmitter 13 transmits the control signal to the receiver 21 of the VISA set. The coded signal is modulated and sent out in the form of an infrared light signal (step 102).

On the other hand, the VSI set receiving unit 21 receives various function command signals from the remote control transmitter 13, and after the VSI microcom 22 first checks it (step 200), the VSI self-diagnosis command continues. It is checked whether or not a signal has been received (step 201).

At this time, if it is determined that the VSI self-diagnosis command signal has been received, the VSI microcomputer 22 performs self-diagnosis for checking the operation state of the important part of the VSI set, for example, the V deck part, the capstan part, and the video signal processing part. (Step 202).

That is, the drum speed / phase sensor units 23 and 24 for detecting the drum motion of the VSI deck portion, the capstan motor speed sensor 25 for detecting the motion of the capstan motor, and the start / end sensing the start and end of the video tape. The sensing data is applied through the sensing means 29 such as the sensors 27 and 26 and the reel sensor unit 28 to determine whether it is in a normal state.

The VSI microcomputer 22 determines when the self-diagnosis is completed as described above (step 203), and then transmits the self-diagnosis result data to the remote control receiver 21 through the V-SIAL set transmitter in the form of an infrared light signal. (Step 204).

On the other hand, the remote control receiver 21 receives the infrared light signal containing the self-diagnosis result data and sends it to the remote control micom 12 side accordingly, the remote control micom 12 determines whether there is received data to decode the data. (Step 103, step 104).

As a result, the LCD display unit 15 displays decoded data indicating the presence or absence of a failure of the VSI set (step 105).

On the other hand, when the user wants to store the above self-diagnosis result data, the user presses the memo key of the key input unit 11. At this time, the remote controller microcomputer 12 determines whether the memo key is input (step 106) and determines that the memory is entered. The decoded data is stored in the section 16 (step 107).

However, if the user presses the reset key without pressing the memo key, the remote controller microcomputer 12 checks this (step 108) and then clears the memo data (step 109).

The VSI / remote control device having a failure diagnosis function according to the present invention as described above automatically executes the self-diagnosis of the VSI set when the user presses the VSI diagnosis key on the remote control, and then checks whether there is a failure or failure part of the VSI set. By displaying on the LCD display unit 15 of the remote control, the after-sales service personnel can make the after-service more convenient in the event of a breakdown of the VSI set.
