Abstract
The invention discloses a light-emitting diode (LED) sport competition countdown displayer capable of dimming. The displayer comprises a main machine casing, a main machine power switch and a power circuit, wherein the main machine casing is provided with a displaying portion, a single chip microcomputer and an RS422 communication portion. The displayer is structurally characterized in that the single chip microcomputer is connected with a manual button on an external device through the RS422 communication portion, and the single chip microcomputer is in communication connection with the displaying portion. Therefore, the lighting degree of the countdown displaying portion can be adjusted manually, requirements of a field can be met, vision requirements of sportsmen can be met, and normal competitions of sportsmen are not affected. The displayer can be used for countdown of playing time of competitions such as football competitions, basketball competitions, table tennis competitions and badminton competitions, so that sportsmen can know the playing time accurately.
Description
Technical field
The invention belongs to the physical culture field of display devices, relate in particular to a kind of display of LED sports tournament countdown of tunable optical.
Background technology
At present; General school, office, particularly some small-sized companies, unit are when carrying out sports tournament, no matter be out of doors or indoor; Bright secretly can not the adjusting of some LED match countdown device display parts of usefulness; Eyes are to the adaptation of match countdown device on the ground at different to be difficult to meet the sportsman like this, and this will have influence on athletic normal match.
Summary of the invention
The objective of the invention is to realize like this; The display of the LED sports tournament countdown of described a kind of tunable optical; Comprise host housing, host power switch and power circuit; Host housing is provided with display part, single chip microcomputer and RS422 communication part, and its design feature is that single chip microcomputer passes through that hand push button is connected on RS422 communication part and the external unit, and single chip microcomputer carries out communication with the display part and is connected.
The object of the invention can also be realized through following technical scheme, the display of the LED sports tournament countdown of described a kind of tunable optical, and to be the display part be made up of light emitting diode that can the dot matrix display digit its characteristics.
The object of the present invention is to provide a kind of bright dark degree simple in structure, that can come to regulate the display part arbitrarily through the processing of single chip microcomputer to meet the display of human eye to the LED sports tournament countdown of a kind of tunable optical of the demand of light.
The present invention with existing common countdown display in comparison biggest advantage is: enable manual is regulated the bright dark degree of countdown display part, adapts to the requirement in on-the-spot place, can meet athletic visual requirement, can not influence athletic normal match.The display of the LED sports tournament countdown of this brand-new tunable optical of the application of the invention comes to be vast middle-size and small-size enterprises and institutions and school's service.The present invention can be used for the fixture countdown of matches such as football, basketball, table tennis, shuttlecock, makes the sportsman can accurately hold fixture.
