[Technical field to which the invention belongs]

 The present invention relates to a meter used in a transport aircraft, and more particularly to a meter having an alarm function of changing color and generating a warning sound. It is possible to change the color and at the same time emit a warning sound or a synthetic voice to warn the driver of excessive speed of the car or abnormal operation, and it is used in cars etc. that use a light emitting plate as a light source. It is about meters.

[Prior art]

 In conventional transport aircraft such as airplanes, ships and automobiles, night vision lamps are often used on meters to allow drivers to read the data on the meter in dim light. FIG. 1 shows the internal structure of a conventional speedometer. In this conventional speedometer, a light bulb 2 is arranged behind a panel 1 with a certain distance, and is made of a material having good photoconductivity. A transparent ring 3 is fitted around the peripheral edge of the panel 4. The light bulb 2 emits light on this ring 3, and the ring 3 evenly projects four lights on the panel. Such meters are quite heavy, bulky and large. Furthermore, the photoconductivity of the ring 3 hardly meets the optimum conditions and some blind spots in the illumination of the meter have to be overcome. The reason why the conventional meter is heavy and bulky is that the light bulb 2 is located at a position apart from the panel 4 with a certain projection distance so that the light source can effectively project the light on the ring 3. It has to be installed. If this distance is too close, the light will be focused in a narrow area of the ring 3. When this happens, the illumination of the meter will not be quite uniform and most of the area of the meter will receive poor illumination, while the narrow area of ring 3 mentioned above is over-illuminated. Due to physical limitations, the light output of conventional meters could not be reduced.

[Problems to be solved by the device]

 Recently, light emitting plates have been developed to replace conventional light bulbs and diodes. Commercially available electronic products such as telephones, mobile phones, audio equipment, musical instruments, and watches use light and thin light emitting plates instead of conventional light bulbs and light emitting diodes. This method has significantly reduced the size of conventional meters. More importantly, the light emitting plate provides a very uniform illumination so that no blind spots occur on the meter. Therefore, the driver can read the meter data without feeling uncomfortable. Furthermore, the soft lighting makes the atmosphere inside the car soft and enhances passenger comfort.

However, in the field of meters, the usage of the light emitting plate is not sufficiently known. The light emitting plate is so thin that it can be cut to any contour. This allows the meter to be freely designed in any shape with no restrictions. Conventional light bulbs are much bulkier and can only be used as illuminators. Light emitting plates, on the other hand, have been developed with different basic colors, and this color can be used to fully represent the various operations of the vehicle.

Therefore, a first object of the present invention is to make a meter used in a transportation machine have an alarm function such as a color change and a warning sound. In this meter, various light emitting plates are used. Different colors are connected to different detection circuits, which will cause the light emitting plates in the various areas of the meter to light up when the vehicle or other transport aircraft is in an operating state in which it exceeds a preset value. When activated, it emits light in combination with the warning sound and the synthetic voice to achieve the warning effect by the synthetic sound and the light.

A further object of the present invention is to provide a meter in which a multi-layered light emitting plate having various different colors is used so that the light emitting device is connected to different detection circuits and warning circuits.

[Embodiment of the invention]

 An embodiment of the present invention will be described with reference to the drawings. 2 and 3 show a meter panel 10 of a first embodiment of the present invention, made of a transparent plastic material and generally circular in shape. However, the shape of the meter panel can be formed into any geometric shape according to the design requirements. A flange portion 15 protruding outward is formed on the peripheral edge of the meter panel 10. At the center of the panel 10, a circular hole 10a through which the pointer shaft 30 passes is formed for attaching the pointer 20. The meter panel 10 is pre-divided into several areas with different sizes according to the manufacturing conditions of the meter manufacturer. Then, several types of light-emitting plates 40 capable of emitting light of different colors are cut according to the shape of the corresponding and attached areas.

After that, the detection elements in the detection circuit of the meter are connected to the light emission control section 41 of the light emitting plate 40 through the respective wires. When the detector detects that the engine operating speed of a transport machine such as an aircraft, a ship, or an automobile, running data such as temperature and pressure is a set value, the light emitting plate 40 in the corresponding area is detected. It is controlled and emits light. When the detected value changes and exceeds a certain value, the control circuit 41 controls the light emitting plate in another area to operate so as to emit light. This design uses different colors such that the meter indicates green for safety, yellow for caution, red for the driver to be alert to the current state of the aircraft, and dangerous. Can be used continuously, which is very advantageous. If the light from the meter was a warning red color, the engine should be stopped immediately to check if the engine needs repair. At the same time, when a light emitting plate in another area is energized and emits light, the detector also emits a warning sound or a synthetic voice to alert the driver to changes in the operating state of the vehicle. Let them notice. Thus, the light and sound effects are combined to enhance the function of the meter.
