Description

A monitor for a pose-correction using a contact sensor

The present invention relates to a posture correction monitor using a touch sensor, and in particular, a touch sensor is attached to a chair on which the worker sits and detects the worker's posture by the touch sensor to output a warning message on the screen. It relates to a posture correction monitor using a contact sensor.

In general, a water tube (CRT) used in a monitor focuses and accelerates hot electrons emitted from R, G, and B guns, and collides with R, G, and B fluorescent surfaces through a point on a shadow mask to form pixels. The sawtooth wave flows through the horizontal deflection coil to form a two-dimensional screen.

These monitors are largely divided into a video system for processing video signals, a deflection system for vertical and horizontal deflection, and a power system. The microcomputer controls each system of the above-described monitors, and a problem occurs or When an externally provided key is pressed, a self-diagnosis operation is performed and the result is displayed on the screen of the receiving tube through an on-screen display.

Here, the "On Screen Display (OSD)" in the monitor means that the user can adjust various parameters related to image quality (e.g., contrast, horizontal size, pincushion, vertical size, etc.). It is indicated on part of or when an abnormal condition occurs on the monitor.

Here, the process of displaying the parameter adjustment menu, which is the main function of the on-screen display, shows that in most monitors, when the user presses the menu key, the microcomputer recognizes this and then controls the on-screen display integrated circuit (OSD IC) to display the on-screen display. Menus related to parameter adjustment are displayed on the screen, and when the user selects the parameter to be adjusted by using the selection key, the current setting status of the parameter is displayed as a bar, and the user sets the parameter data using the up-down key. The value can be changed.

That is, FIG. 1 is a circuit diagram showing a conventional video related part in a monitor, which is a horizontal synchronous signal from the video preamplifier 10, the blanking unit 11, and the FBT 12 to the flyback pulse FBP. OSD IC 13, mixer unit 14, video output circuit 15, and water tube (CRT) which are input as H.sync and output R, G, B signals for on-screen display (OSD) And the like.

The video preamplifier 10 amplifies the main R, G and B signals input from the video card of the computer through the D-sub connector, and adjusts the amplification degree according to the contrast signal of the microcomputer (not shown). Adjust the brightness.

That is, since the video signal input through the de-sub connector is a low signal of about 1 V or less, the video preamplifier 10 amplifies the AC gain of about 4 to 10 and then receives the CRT from the video output circuit 15. Amplify the signal from approximately 30V to 50V to drive the cathode. Since the video output circuit 15 is a fixed gain amplifier, the video preamplifier 10 can adjust the level of the video signal.

The blanking unit 11 blocks the output of the video preamplifier 10 when the OSD R, G, and B signals are output according to the fast blanking (FB) signal output from the OSD IC 13. That is, when the OSD IC outputs 'high' as a fast blanking (FB) signal, a forward bias is applied to the transistor Q2 through the diode D1 and the resistor R3 to turn on the transistor Q2. Accordingly, the diodes D2, D3, and D4 connected to the R, G, and B output terminals of the video preamplifier 10 are turned on to block the output of the video preamplifier 10.

As mentioned above, a monitor refers to a device for receiving information from a computer system output and a synchronization signal and displaying information on a Cathode Ray Tube (CRT) screen. It is long already.

However, when a worker is working in front of the monitor for a long time, there is a problem that the posture is unintentionally disturbed, which puts a burden on the worker's body, especially the waist.

Therefore, the present invention was devised to solve the above problems, and attaches a touch sensor to a chair on which the worker sits and detects the worker's posture by the touch sensor to output a warning message on the screen if the posture is distracted. It is an object of the present invention to provide a posture correction monitor using a contact sensor.

The touch sensor 10 is for detecting whether the worker's posture is correct, and the first contact sensor 10-1 detects whether the upper back of the chair 100 and the upper part of the back of the worker are in contact with each other. If not, a non-contact signal is output, and the second contact sensor 10-2 detects whether the backrest / seat interface of the chair 100 and the buttocks of the worker are in contact with each other and outputs a non-contact signal if they are not in contact.

The light emitting units 20-1 and 20-2 of the infrared sensor 20 receiving the non-contact signal emit an optical signal, and the light receiving unit 20-3 of the infrared sensor 20 receives the optical signal to receive electricity. The signal is converted and output.

When the microcomputer 30 receives an electric signal from the light receiving unit 20-3 of the infrared sensor 20, the microcomputer 30 considers that the worker's posture is disturbed and outputs a control signal to the on-screen display integrated circuit 40.

In response to the control signal of the microcomputer 30, the on-screen display integrated circuit 40 outputs the corresponding character information (eg, “correct posture”) to the video output circuit 50.

Accordingly, the video output circuit 50 amplifies the character information output from the on-screen display integrated circuit 40 and displays it on the picture tube (CRT) screen.

As described above, the device according to the present invention attaches a touch sensor to a chair on which the worker sits, detects the worker's posture by the touch sensor, and outputs a warning message on the screen if the worker's posture is disturbed. If you work in front of the monitor for a long time, you can correct the posture that is easy to be distorted.
