Abstract

PURPOSE:To visualize the time after a change of a weather forecast by varying a display pattern of a display means in accordance with an elapsed time after the time point when a detecting means detects a change of predicted weather by a display control means. CONSTITUTION:When weather is predicted, whether weather predicted in the next time is the same as weather displayed at present or not is decided. In this case, when the predicted weather and the weather displayed at present coincide with each other, a regular display, namely, flickering of a prescribed period is contained by a display means 2. The display means 2 executes flickering by a prescribed period in the case of the regular display, but in the case the predicted weather and the displayed weather do not coincide with each other, flickering of two times is executed for a prescribed time within one period of the regular display, and thereafter, the regular display is executed. In such a way, in the case flickering of two times is executed within one period of the time of the regular display, it is known that it is before long after the display is changed.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a weather forecast display device, and more particularly to a weather forecast display device that predicts and displays weather based on changes in atmospheric pressure.

Conventional technology There is a weather prediction device that detects atmospheric pressure using a diaphragm, stores the atmospheric pressure, predicts future weather based on past patterns of atmospheric pressure changes, and displays the predicted weather. Ta.

Conventionally, in such a weather forecasting device, the lamps 18 provided corresponding to the display section 17 indicating sunny, cloudy, and rain as shown in FIG. 11(A) are set at a constant value as shown in FIG. The weather was displayed by flashing at a cycle of .

Problems to be Solved by the Invention However, as shown in FIG. 11(B), conventional weather forecasting devices do not simply detect weather forecasts when the pattern of changes in atmospheric pressure changes from a display predicting clear skies to a display predicting cloudy skies, for example. Because the constant flashing light only changed from clear to cloudy, there were problems such as not knowing when the weather forecast changed even if it changed.

The present invention has been made in view of the above points, and an object of the present invention is to provide a weather forecast display device that notifies users of changes in weather forecasts.

Means for Solving the Problems The present invention provides a weather forecast display device that detects atmospheric pressure, predicts future weather based on the change in atmospheric pressure detected by a prediction means, and displays the predicted weather predicted by the prediction means on a display means. , a detection means for detecting a change in the predicted weather of the prediction means; and when the detection means detects a change in the predicted weather of the prediction means, the detection means detects a change in the predicted weather of the prediction means; A display that controls the display means so that the display pattern varies depending on the elapsed time.
It is equipped with 11 control means.

Alternatively, the configuration may include elapsed time display means for displaying the elapsed time from the time when the detection means detects the history of predicted weather changes.

Further, an arrangement may be made in which an alarm means is provided which generates an alarm when the detection means detects a change in the history of the predicted weather by the prediction means.

Furthermore, a display unit that displays predicted weather predicted in the past;
The forecasted weather on the display unit is updated in accordance with the update of the forecasted weather displayed on the display means every predetermined time.<t. lJIIl
It is good also as a structure which comprised the means.

When the detection means detects that the weather displayed by the effect display means has changed, the way the weather is displayed on the display means changes depending on the elapsed time from the time of change. Therefore, depending on the way the weather is displayed on the display, it can be determined how long the weather has been displayed.

Furthermore, by providing a display section for displaying the elapsed time on the display means, it is possible to know from when the display has been displayed. In other words, it is possible to recognize when the switch was made.

Furthermore, by generating an alarm when the display changes, it is possible to recognize changes in the weather.

It also displays past predicted weather along with current weather,
By updating these displays at predetermined intervals, it is possible to know the trends in predicted weather changes.

Example FIG. 1 shows a block diagram of a first embodiment of the present invention.

In the figure, 1 is an atmospheric pressure sensor which is a detection means, 2 is a display means,
3 shows a control circuit which is a prediction and display tIIJII1 means.

The atmospheric pressure sensor 1 includes a diaphragm and a photointerrupter,
It is composed of an A/D converter and the like.

The surface of the diaphragm is displaced in response to atmospheric pressure, and a shielding plate is provided on the surface of the diaphragm, and a photointerrupter is arranged to sandwich the shielding plate. When the atmospheric pressure changes, the surface of the diaphragm is displaced and the shielding plate is displaced. When the shielding plate is displaced, the amount of light from the light emitting section to the light receiving section of the photointerrupter changes, and the output voltage changes. The output voltage is A/D (analog/digital) converted by an A/D converter and output as atmospheric pressure data.

III m circuit 3 is microcomputer 4. It consists of a RAM (random access memory) 5. The atmospheric pressure data from the atmospheric pressure sensor 1 is stored in the RAM 5 at any time.

The microcomputer 4 predicts the weather based on the pattern of changes in the atmospheric pressure data stored in the RAM 5, and supplies display data according to the prediction to the display means 2. The display means 2 is configured to perform display according to display data from the microcomputer 4.

Next, the operation of the apparatus will be explained with reference to FIG.

New atmospheric pressure data is constantly supplied to the RAM 5 from the atmospheric pressure sensor 1 via the microcomputer 4, and I! After being stored, the data is discarded. The microcomputer 4 is supplied with atmospheric pressure data from the RAM 5, and the microcomputer 4 predicts the future atmospheric pressure based on the pattern of changes in the past atmospheric pressure data from the RAM 5, and predicts the weather in the future (several hours later) based on the predicted atmospheric pressure. Steps 6 and 7).

After predicting the weather, it is then determined whether the predicted weather is the same as the currently displayed weather (step 8). If the predicted weather is the same as the currently displayed weather, the display means 2 will continue to display the currently displayed weather as normal, that is, it will continue to blink at a constant cycle (Step 9).
.

At this time, if the predicted weather is different from the currently displayed weather, the display that notifies you that the currently displayed weather will change will blink twice during the regular blinking cycle of the normal display in this embodiment. is displayed for a certain period of time (step 10.11). Thereafter, normal display is performed (step 9).

For example, as shown in FIG. 4<A), when the forecast changes from clear to cloudy at time
Previously, it flashed at a constant cycle, which was a normal display, and turned off at time t+JJ,m. In addition, the lamp 13 that displays cloudy weather, which is the next forecast, as shown in FIG. Instead of blinking once, it blinks twice in one cycle. After a certain period of time, a display indicating a change in the forecast that is different from the normal display will be displayed.
At time t2, the display becomes normal.

The display means 2 blinks at a constant frequency in the normal display, but if the predicted weather and the displayed weather do not match, the display means 2 blinks twice in one cycle m of the normal display at a constant frequency. After a pause, the normal display is performed. In this way, if the blinking occurs twice during one round IlI during normal display, it can be seen that the display has recently changed.

Further, FIG. 5 shows a diagram for explaining the operation of the second embodiment. The configuration is the same as the first embodiment, and the operation is such that the lighting time is changed according to the time since the display changed as shown in FIG. You can see if there have been any changes to the forecast.

Further, FIG. 6 is a diagram for explaining the operation of the third embodiment, and its configuration is the same as that of the first embodiment.

As shown in FIG. 6, when the prediction is changed and the display changes, the time elapsed since the prediction was changed can be determined by increasing the number of blinks according to the time from the time when the display changed.

FIG. 7 is a plan view and a diagram for explaining the operation of the display section of the fourth embodiment, and its configuration is the same as that of the first embodiment. As shown in FIG. 7(A), the display means 19 is provided with a display section 20 for displaying past weather.
As one means, the prediction is updated and displayed at predetermined time intervals using a microcomputer or the like. As shown in FIG. 7(B), the current predicted weather moves to the left at predetermined intervals. In this way, predicted weather trends can be recognized at a glance.

Further, as shown in FIG. 8, the previously displayed weather is displayed in a manner that is less bright than the currently displayed weather, so that changes in the weather forecast can be seen.

FIG. 9 is a plan view of the display means of the fifth embodiment and a diagram for explaining the arrangement, and this display means is also controlled by the microcomputer 4. As shown in FIG. 9(A), a bar graph display 16 indicating the time since the weather display was changed is placed close to the weather display pattern 15 to indicate the time since the weather display was changed. be able to recognize the time since

Further, FIG. 10 is a block diagram of the sixth embodiment. In the above embodiments, the change history of predictions can be understood by changing the display pattern, but in this embodiment, the 10th embodiment
As shown in the figure, even if the alarm generating means 20 is connected to the microcomputer 4 to notify the user by voice when the forecast changes, it is possible to recognize that the predicted weather has not changed.

Effects of the Invention As described above, according to the present invention, the detecting means detects a change in the predicted weather of the forecasting means that predicts the weather based on changes in atmospheric pressure, and the detecting means detects the change in the predicted weather by the display and inspection means. Since the display pattern of the display device differs depending on the time elapsed since the time of detection, it is possible to see how long it has been since the predicted weather changed, and how much time has passed since the weather was displayed. You can know what you did,
Furthermore, by providing an alarm generation means that generates an alarm when the detection means detects a change in the predicted weather, an alarm will be generated when there is a change in the predicted weather, making it possible to recognize changes in the predicted weather. Furthermore, in addition to the display means, by providing a shuttle display means for displaying the elapsed time from the time when the detection unit detected a change in the forecasted weather, it is possible to see at a glance the time elapsed since the forecasted weather changed. Because it is visible, it is possible to know how long ago the predicted weather changed.Furthermore, in addition to the display means, the display unit that displays past predicted weather and its front foot can be used to display predicted weather at a predetermined time. Since the forecast weather is updated hourly and is provided with a < fil control means, it is possible to know the predicted weather for a predetermined time before, so it is possible to know when the forecast weather changed to the current forecast weather displayed on the display means. It has features such as being able to
