Abstract

PURPOSE: To attain the increase of display information quantity, prolongation of life of luminous body and the reduction of consuming electric power by a method wherein when the river condition changes, it is displayed by increasing brightness and after a certain time, the brightness is lowered.
CONSTITUTION: The river is divided according to each water level observation section and a screen 6 to display the river state is installed, then, a projection is performed through luminous units each of which is composed of the red, green and blue of luminous bodies 7W9. A control system 11 is connected to the units 4. A certain unit 4 is specified by an address signal 13 from a river information processing system 10. And further, a drive signal 21 is outputted by means of data D4WD6 specifying colors and a signal 14 displaying brightness level L1WL3, thus, in accordance with the state, brightness display is performed. Combination of drive signals 21 allows the lunination of 7 colors and the brightness of 8 levels. The system 10 gradually lowers brightness after certain time. Therewith, in accordance with the change of state, various colors and brightness are displayed, thus, information quantity is increased and electric power consumption is reduced.
