摘　　要：研制多色激光动画表演系统,采用上下位机方式实现单台电脑控制多台激光投影器的系统结构,实现多色、多台激光投影器同步表演图文动画功能。每台激光投影器由各自的激光表演软件实现图文动画的编辑和投影,所有表演软件由电脑上的系统控制软件统一调用,实现按照预先给定时间段的自动表演。采用提高进程优先级的方法使系统控制软件的实时性得到提高,使线程能够尽快且同步地完成函数相应动作,确保表演过程中不同激光投影器之间动作的协调。Develop a laser-performing system with different colors. Use one computer to control several laser performers based on client/server structures so that the cartoons of graphics and text can be displayed in the same time. The cartoons of graphics and text on each laser performer can he edited and displayed independently by a performing program in the computer. Several copies of performing programs are controlled by the controlling software. The given time-list for performances can be executed automatically. The priority of the controlling software is increased so that all performing programs will loaded synchronously. The system has been running well for two years.
