Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a river condition display method, and particularly to a display method suitable for displaying river conditions in a wide area.

Conventional methods of displaying river conditions on large panels, etc. are mostly numerical display methods, such as Nixie displays, LED displays, etc. placed on the map board, or table formats, bar graph formats using lamp displays, etc. be.

Therefore, there is a drawback that it is difficult to quickly and intuitively accurately grasp the situation of rivers and rainfall over a wide area.

Conventionally, it is a display device mainly used for advertising display lights, etc., in which the display surface is divided into multiple parts of a certain size, and the combination of the divided screens is used to perform a meaningful screen display or to display characters, etc. Most of them are things.

However, in cases such as rivers, it is more convenient to have a display device that allows you to see the status of a fixed pattern at a glance, rather than assembling a screen arbitrarily.

The purpose of the present invention is to improve the shortcomings of these conventional methods and to quickly and accurately grasp river conditions such as rivers and rainfall over a wide area by displaying them in different colors, for example, according to river conditions such as rivers and rainfall. The purpose of the present invention is to provide a river information display method that makes it possible to display river information.

A feature of the present invention is that multiple rivers are divided into areas where the river conditions can be grasped based on the water level at each observation point and displayed on a topographic map, and the divided rivers are color-coded and divided according to the water level situation. I once made it possible to display increases and decreases in water levels near rivers.

Embodiments of the present invention are shown in FIGS. 1, 2, 3, and 4. On the water level display board 1 in Figure 1, a map 2 of the Tohoku region is drawn, and on this map 2 rivers 3
is depicted. As shown in Fig. 2, this river 3 has a screen 6 ( _6-1 to _6-5 ) showing the shape of the river for each observation section divided into water level observation stations, and a water level increase/decrease indicator 5 ( _5-1 to 5-5). _-12 ) are provided. This screen 6 is illuminated by a light emitting unit 4 comprising a light emitter (red) 7, a light emitter (green) 8, and a light emitter (blue) 9 as shown in FIG. On the other hand, the light emitting unit 4 and the water level increase/decrease indicator 5 are connected to a control device 11 comprising a gate 16, an address decoder 17, a data buffer 18, a data memory 19, and a driver 20, as shown in FIG. .

This is because the light emitting bodies 7, 8, and 9 display a plurality of colors depending on the combination thereof, and here a case is shown in which a combination of three primary colors is used.

The divided rivers _6-1 to _6-5 are formed as faithfully as possible to the actual river shape, and are divided according to the jurisdictional range of the water level observation point. The water level increase/decrease indicators _5-1 to _5-12 , etc. indicate changes in the water level detected by water level detectors installed in the divided rivers, for example, from the previous measurement value. The arrow corresponds to a decrease.

In FIG. 4, the river information processing device 10 inputs water level information from each observation point and determines whether or not it is necessary to change the light emission status of each light emitting unit. Now, the river information processing device 10 sends an address signal 13 that specifies the light emitting unit 4, data that specifies a color corresponding to the quantized river water level, data 14 that indicates an increase or decrease in the water level, and specifies the timing to capture this signal. When the timing signal 12 is output, the control device 11 takes in the address signal 13 via the gate 16 according to the timing signal 12, and outputs the address signal 13 to the address decoder 17.
generates a memory selection signal 15 in
5, output from the river information processing device 10
Data signal 14 of D ₁ to _{D 5} is data buffer 1
8 to the data memory 19.
Based on this set data, drive signals 21 of R, G, B, U, and D are outputted from the data memory 19 to the light emitting unit 4 and the water level increase/decrease indicator 5. With this combination of drive signals, the light emitting unit can emit light in seven colors by individually emitting each color of R, G, and B with a light emitting body such as a lamp. The increase/decrease indicator makes it possible to express the rise and fall of the water level.

For example, an example of the operation will be described with reference to FIGS. 5A and 5B in the case where the river conditions of the light emitting unit in a certain section change and the direction must be changed from G to R or from D to U. The river information processing device 10 first receives an address signal 13.
(A ₁ = 1, A ₂ to A ₈ = 0), data signal 14 (D ₁ =
1, D ₂ = 0, D ₃ = 0, D ₄ = 1, D ₅ = 0), and then a timing signal 12 for taking in the address signal 13 and data signal 14. In the control device 11, an address signal 13 (A ₁ =1, A ₂ to _{A 8} =0) is sent via the gate 16.
is detected at the rising edge of the timing signal 12, and the address decoder 17 decodes this data, thereby generating the memory selection signal 15 at address 1. On the other hand, a data signal 14 (D ₁ =1, D ₂ =
0, D ₃ = 0, D ₄ = 1, D ₅ = 0), the contents of the data memory 19 of the light emitting unit are rewritten by the memory selection signal 15 of the address 1, etc., and the G, D of the drive signal 21 is OFF, R and U are
By turning ON, the light emitting body (red) 7 and the water level increase/decrease indicator 5 (increase) emit light. In this way, the water level of a river in a wide area can be displayed in different colors, and the increase or decrease in water level can be displayed on a large display device using arrows.

In the embodiments shown in FIGS. 3 and 5, a separate water level increase/decrease indicator is provided to indicate only the increase/decrease in the water level and is lit up, but this is omitted and the divided river display is blinked. It's okay. In this case, the blink period may be identified by, for example, a short period when increasing, and a long period when decreasing. In other words, the water level does not change until the display color is changed, but the water level tends to increase or decrease using the same display.

Further, although this embodiment exemplifies the Tohoku region, it is not limited thereto. There are no restrictions on displaying the situation in relation to the terrain or map.

FIG. 6 shows another embodiment of the invention. What differs from FIG. 1 in FIG. 6 is that the light emitting units 4 are provided for each basin of rainfall.

In other words, taking watersheds into consideration, each rainfall observation point is divided into a plurality of areas and displayed in different colors depending on the rainfall situation. Blinking displays in basins where warning rainfall has been reached will make it easier to understand the situation and make it easier to take countermeasures.
Since the amount of rainfall will eventually be reflected in river water levels, it can also be used to predict water levels.

The river information processing device 5 quantizes the rainfall amount for each basin, and the corresponding color-coded data 12 is sent to the control device 1.
4, the light emitting unit 4 provided in each basin emits light.

According to this embodiment, it is possible to display the state of rainfall in a wide area in different colors on a large display device.
