Abstract

<P>PROBLEM TO BE SOLVED: To provide a display device with a fault diagnostic function which ia mounted with a fault detection circuit inside the display device and provided with a function to notify the fault. <P>SOLUTION: The display is mounted with the diagnostic function, detects occurrence of the fault at the time of occurrence of the fault of the disk device and furthermore has a function to notify the occurrence of the fault and the place of the fault occurred. The fault detection circuit is mounted inside of the display device. When the fault occurrs, the display device itself detects it, notifies it to a user by means of e-mail, etc., and notification to a customer engineer is automatically performed. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to maintenance of a display device, and more particularly, to a display device with a failure diagnosis function that includes a failure detection circuit in a main part constituting the display device and reports to a server using a DDC line.

  Currently, there are many cases where display devices (LCD / CRT, etc.) used for server consoles are rarely used during normal server operation. As a result, the server status may not be confirmed because the display device has failed. This makes it meaningless that the display device is connected.

  Japanese Patent Application Laid-Open No. 2004-228561 describes contents for determining a backlight failure in a display device having a backlight.

JP2002-341838

  Patent Document 1 described above has a failure detection function specialized for the backlight of a display device, and does not have a function of determining a failure of each circuit in a circuit constituting the display device.

  The present invention provides a display device with a failure diagnosis function that solves the above problems by mounting a failure detection circuit inside the display device and having a function of notifying a failure.

  According to a first display device with a failure diagnosis function of the present invention, a failure detection circuit for detecting a failure of the circuit is connected to a circuit constituting the display device, and when a failure of the circuit is detected, a DDC line is used for the main unit. And failure information is transmitted.

  According to a second display device with a fault diagnosis function of the present invention, in the first display device with a fault diagnosis function, the circuit includes a power source of the display device, a microcomputer, an FBT, and a CRT. To do.

  The display device with a failure diagnosis function according to a third aspect of the present invention is the display device with the first failure diagnosis function, wherein the main device is a computer device including a server, and receives the failure information through the DDC line. Then, the maintenance staff is notified by electronic mail.

The first effect is that the display device itself can diagnose a failure inside the display device and detect the failure.
The second effect is that when a failure is detected, the server administrator can be automatically notified that the failure has occurred.
The third effect is that notifications to maintenance personnel via telephone lines, etc. enable maintenance response before the user notices that a display failure has occurred, improving the user impression in the maintenance service phase. Can be expected.

Next, the best mode for carrying out the present invention will be described in detail with reference to the drawings.
Referring to FIG. 1, the first embodiment of the display device with a fault diagnosis function according to the present invention includes a display 101, a microcomputer 102, an FBT 103 of a high-voltage step-up transformer, and a power source 104. The display device 10 is provided with one or more failure detection circuits 105 mounted on the parts.
This display device 10 can detect a failure location when a failure occurs. When a failure is detected, the information is passed to the server through the DDC (Display Data Channel) line of the video cable that transmits the control signal, and the failure occurs by means such as e-mail from the server to the system administrator. Notify that it has been done.

Next, the operation of the best mode for carrying out the present invention will be described with reference to the drawings.
Next, the operation of this embodiment will be described in detail.

  Referring to the flowcharts of FIG. 1 and FIG. 2, unlike a normal display device, a display device 10 used in the present invention is a main part for displaying a screen, for example, a display 101 such as a cathode ray tube, a screen, and the like. The display control microcomputer 102, the FBT 103, the power source 104, and the like, and a failure detection circuit 105 for detecting failures of main components are provided.

  A software driver is installed on the server side in order to process a signal notified through the DDC line of the video cable when a failure occurs in the display device.

  When a failure occurs in the display device 10 (step S1), the failure detection circuit 105 detects the failure (step S2), and passes the information along with the failure part to the server side through the DDC line (step S3).

  Here, a signal different from normal DDC data flows through the DDC line. However, such a signal switching is performed by a software driver installed on the server side.

  The server that has received the failure information automatically sends an e-mail to the user, system administrator, maintenance staff, etc. of the site to notify that a display failure has occurred (step S4). It is also possible to notify maintenance personnel at the same time through a telephone line or the like. In this case, maintenance can be performed before the user notices that a display failure has occurred, and improvement of the user impression can be expected in the maintenance service.

  By using the display device 10 having such a function, it is possible to avoid the situation that the server is unable to be confirmed because the display is out of order when the server malfunctions.

  The present invention can be used for a maintenance service that detects a failure of a circuit that constitutes a display device connected to a computer.

It is a block diagram explaining the structure of the Example of this invention. It is a flowchart explaining operation | movement of the Example of this invention.
