TECHNICAL FIELD The present invention relates to a television, and more particularly, to a television abnormal operation warning system that allows a user to take appropriate measures by warning a user when a television malfunctions.

In general, a television receiver is a device for receiving images and sound waves photographed and transmitted using a television camera and a microphone from a transmitting side (broadcasting station) and reproducing the original images and sounds. And a flyback transformer for applying a voltage to a speaker and various circuit boards, CRTs, and circuit boards.

Here, the CRT is a funnel, a panel fused and fused with the funnel, a panel provided with a fluorescent film on an inner side, an electron gun mounted in the funnel to emit an electron beam, and a deflection yoke for deflecting the electron beam emitted from the electron gun. And the electron beam emitted from the electron gun impinges on the fluorescent film to emit light.

Since the inside of the CRT is in a high vacuum state so that the electron beam emitted from the electron gun can reach the fluorescent film well, the funnel and the panel are under a pressure of about 1 atm due to the pressure difference between Brown and the inside and outside. .

According to the pressure difference inside and outside the CRT, tensile stress is applied to the funnel and panel constituting the CRT, which acts as a cause of weakening of the structural strength of the CRT, so that CRT explodes when an external impact is applied. The risk of doing so increases.

On the other hand, according to the television, as described above, components such as CRT tubes that maintain a high vacuum state and flyback transformers that generate a high voltage may cause explosion or fire. In addition to impairing the marketing image of the company, many economic constraints are imposed under the Product Liability Act.

However, conventional TVs are not equipped with a so-called warning system that detects signs of fire or explosion and warns the user to take appropriate measures. Therefore, when a problem occurs, the user may be unprotected. There is a problem that there is no choice but to.

 The present invention has been made to solve the above-described problems, television abnormal operation warning system that can minimize the user's safety and damage to the product by detecting the indication of abnormal operation caused by its own causes and alerting the user to take appropriate measures It is for the purpose of providing.

Television abnormal operation warning system provided to achieve the above object is a temperature sensor for checking the temperature in the product; A controller which compares the temperature sensed by the temperature sensor with a preset reference value and generates a warning signal when the detected temperature exceeds the reference value, and stores an external telephone number that can be contacted in the absence of the user; An on-screen display (OSD) device for converting a warning signal of the controller into an on-screen display warning image signal; A display driver scanning the warning image signal provided by the OSD device; A display device for displaying a warning video signal as an image on a screen; A codec for converting a warning signal of the controller into a warning sound signal; A multiplexer for dividing the warning sound signal transmitted from the codec and the broadcast sound signal transmitted from the voice signal processor connected to the tuner and transmitting only the warning sound signal to the speaker; A key input unit for enabling a control operation of the control unit by the user; A power control unit connected to the control unit and configured to include a mechanical power switch to cut off the main power through a user's key input unit, and an electrical power switch to block only the operation power required for the operation of the CRT and maintain a standby power at the control unit's judgment; It is configured to include a modem that receives the warning signal from the control unit and delivers it to the communication means of the user.

Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 1 and 2.

The television abnormal operation warning system according to an embodiment of the present invention compares the temperature sensed by the temperature sensor 10 and the temperature detected by the temperature sensor 10 with a preset reference value as shown in FIG. 1. A controller 12 for generating a warning signal when the detected temperature exceeds a reference value, an OSD device 20 for converting the warning signal of the controller 12 into a warning image signal of an on-screen display method, and the OSD device ( A display driver 22 for scanning the warning image signal provided by the display device 20, a display device 24 for displaying the warning image signal as an image on a screen, and a codec for converting the warning signal of the control unit 12 into a warning sound signal ( 30 and the warning sound signal transmitted from the codec 30 and the broadcast sound signal transmitted from the voice signal processing unit 33 connected to the tuner 32 to transmit only the warning sound signal to the speaker 34 The power supply state of the product is determined based on the multiplexer 36, the key input unit 40 for allowing the user to control the control unit 12, and the operation of the key input unit 40 or the judgment of the control unit 12. It includes a power supply control unit 50 to adjust, and the modem 60 receives the warning signal from the control unit 12 and transmits to the communication means of the user.

Here, the control unit 12 is a temperature comparison function is added to the existing microcomputer that controls the overall function of the television and also performs a function of storing an external telephone number that can be contacted in the absence of the user input operation.

In addition, the power control unit 50 is connected to the control unit 12, the mechanical power switch 52 to cut off the main power through the operation of the user's key input unit 40, and the operation of the CRT at the judgment of the control unit 12. It consists of an electrical power switch 54 which cuts only necessary operating power and maintains standby power.

Referring to the operation method of the television abnormal operation warning system according to an embodiment of the present invention configured as described above are as follows.

First, a warning signal generation step in which the control unit 12 generates a warning signal when an abnormal operation phenomenon such as overheating of some parts occurs during use of the television and the temperature detected by the temperature sensor 10 exceeds a preset reference value. (s10) proceeds.

Subsequently, the OSD device 20 converts the warning signal generated by the controller 12 into a warning image signal of an on-screen display method, and the display driver 22 scans the warning image signal again, and displays the warning image signal. A warning image display step (s11) of displaying on the screen as a warning image is performed.

At the same time, the codec 30 converts the warning signal generated by the control unit 12 into a warning sound signal, and transmits the warning sound signal transmitted from the codec 30 and the voice signal processor 33 connected to the tuner 32. The warning sound generating step (s12) for separating the broadcast voice signal by the multiplexer 36 and transmitting only the warning sound signal to the speaker 34 is also performed. In the warning sound generating step (s12), the broadcast voice signal is stopped and the warning sound is generated. Only the sound can be heard so that the user can see the abnormal operation even without looking at the screen.

Finally, when the user detects an abnormal operation state through the warning image and the warning sound, and operates the key input unit 40, the control unit 12 of the product through the power control unit 50 mechanical power switch 52 The main power cutoff step (s13) of cutting off the main power is performed.

That is, according to the present embodiment as described above, when an abnormal operation such as overheating of the television occurs while the user is watching the television, the user may receive a warning sound or a warning sound through the warning image and the speaker 34 on the screen. By being able to know visually and audibly, the user can immediately take appropriate action (main power off) to prevent the damage caused by the explosion or fire of the television.                     

On the other hand, the television abnormal operation warning system according to the present embodiment is to perform the so-called remote control operation to notify the remote user of the abnormal operation occurring in the absence of the user, and to take action on the abnormal operation. Is as follows.

First, when there is no response from the user through the operation of the key input unit 40 for a predetermined time in the warning image display step s11 and the warning sound generation step s12, the user is considered to be absent and the control unit 12 The operation power cutoff step s14 is performed to cut the operation power through the power switch 54.

When the operating power is cut off, the telephone is connected to the user by the telephone number previously input to the control unit 12 through the modem 60 using the standby power. At this time, the user receives a warning image or a warning sound. The remote warning step (s15) is performed.

In addition, when there is a response from the user in the remote warning step (s15) or no response for a predetermined time, the main power cutoff step (s16) of the mechanical power switch 52 cuts off the main power is performed.

According to the remote control operation, when the user forgets to turn off the television and goes out, or the television is operated by the reservation function in the absence of the user, the television stops even if there is no response by the user when an abnormal operation occurs. It is possible to prevent damage caused by explosion or fire.

 In addition, when a malfunction occurs, the main power is not immediately cut off, and the user is notified, so that the user does not cause an error of continuing to use the TV without checking the status of the malfunction.

In particular, according to the remote control operation, it is possible to effectively cope with the case where the abnormal operation phenomenon occurs while only the infant or the elderly who have insufficient ability to deal with the situation are watching television.
