本文简要介绍了电脑多功能计时计分大屏幕显示系统。其内容包括:系统的组成、显示原理和显示方式,系统中的微计算机以及驱动电路和屏幕显示的控制等。该系统是一个用汽车灯泡作发光元件,构成分块式点阵的假“满天星”屏面,并采用5台Z-80单板机进行分布控制的大屏幕显示系统,现已安装在南京航空学院体育馆内,经多次使用表明,它在汉字、西文、计时计分的显示以及技术资料统计等功能上均符合国际、国内篮、排球等比赛要求,在同类系统中已达到国内先进水平。采用多台Z-80微计算机间的通讯进行分布控制来实现多功能大屏幕显示,是本系统的一大技术特色。
This article briefly introduced the computer multi-function timing scoring large screen display system. Its contents include: system composition, display principle and display mode, the system of micro-computer and drive circuit and screen display control. The system is a large-screen display system that uses a car bulb as a light-emitting element to form a sub-glittering “gypsophila” screen with a sub-block lattice and distributed control using five Z-80 single-board machines, Nanjing University of Aeronautics and Astronautics Gymnasium, after repeated use shows that it matches the requirements of international and domestic basketball, volleyball and other games in the functions of Chinese characters, western languages, the timing score display and technical data statistics, has reached the domestic Advanced level. Using multiple Z-80 microcomputer communication between the distribution control to achieve multi-function large-screen display, the system is a major technical features.
