Abstract
The utility model provides a display used for breaking rules with seven times in basket ball matches, which is composed of a display device and acontroller, wherein, the display device comprises a chassis, a three cylindrical surface display screen which is fixed on the chassis, and an indicating lamp which is arranged on the top of the display screen. The utility model can simultaneously display digitals ranging from one to seven on three cylindrical surfaces, and a viewing angle can reach 360 DEG. The utility model has the advantages of clearly displaying numbers and convenient operation.
Description
The utility model relates to a kind of relevant height sport device, particularly relates to seven foul of a kind of basketball display.
Early stage basketball seven times foul shows it is that, yellow flag red to place at the Judge Seating two ends is mark, is not enough to show the number of times situation before the foul seven times, is difficult for causing that referee, sportsman and spectators note.Also made a kind of foul display unit now, promptly display screen is divided into seven layers, the once bright one deck of breaking the rules.This display unit is that single face shows, maximum 150 ° of visual angle, and light-emitting component adopts bulb, the life-span is short, power consumption is big, seven foul completely do not have distinguishing mark.
The purpose of this utility model is to be to provide a kind of three cylinders to show synchronously, and the visual angle reaches seven foul of basketball display of 360 °.
The utility model basketball seven times foul display is achieved in that it is made of the indicator lamp that its display unit comprises the chassis, is fixed on three cylinder display screens on the chassis and is arranged on three cylinder display screen tops display unit and controller.The chassis can be different shape, and three cylinder display screens generally are the triangular column, and adopts the seven segment code of high brightness LED composition to show 8 word lamp plates, and dust cover is made with lucite in the outside, and the demonstration numeral is advisable with green or yellow.The indicator lamp at its top is red, and sparkling, and when seven foul had been expired, indicator lamp was promptly shinny, notes to remind referee, sportsman, team bench, chief referee and recorder.Controller is connected input control signal by plug connector with three lenticular display.Controller circuitry comprises power supply, indicator lamp flicker control circuit, counting circuit, drive circuit and display circuit, it is connected to, power supply connects the input of indicator lamp flicker control circuit, counting circuit, drive circuit and display circuit respectively, counting circuit output connects the drive circuit input, drive circuit output connects the display circuit input, and counting circuit and drive circuit output connect the input of indicator lamp flashing circuit simultaneously.Wherein the indicator lamp flashing circuit is made of gate circuit and 12 binary string linage-counters and controllable silicon; Counting circuit is made of decimal system reversible counter and peripheral circuit thereof; Drive circuit is made of diode BG; Display circuit is made up of light emitting diode.By decimal system reversible counter output seven segment code, make display screen luminous through drive circuit, " 7 " inferior demonstration is by gate circuit and 12 binary string linage-counter output gap signals, the luminous and flicker by the SCR control indicator lamp.
The advantage of seven foul of the utility model basketball display is, 1-7 foul times can be shown on three cylinders synchronously, the visual angle reaches 360 °, satisfy different azimuth and watch, the top red lamp flass represents that 7 foul are full, display operation is convenient, volume is little, long service life, power consumptive province, generally can connect two display unit simultaneously, is placed on the operating desk two ends and uses.
Describe the utility model embodiment in detail below in conjunction with accompanying drawing.
