基于proteus平台，采用8086处理器，利用汇编语言编写，可作为微机原理课程设计。设计一套十字路口的交通灯管理系统，通行时间（或禁止时间）30秒，准备时间3秒，在准备时间里黄灯闪烁3次，闪烁频率为0.5秒，周而复始。若有紧急情况（救护车通过），申请中断，四个方向全部红灯，10秒后重新开始。（进一步设计，可以利用实验箱上的多位数码管显示两个方向的倒计时，或LED点阵显示停、行汉字或动画）(Based on the Proteus platform, using 8086 processors and compiled in assembly language, it can be used as a microcomputer principle course design. Design a set of traffic lights management system at crossroads, traffic time (or no time) 30 seconds, preparation time 3 seconds, in the preparation time, yellow light flashes 3 times, flickering frequency is 0.5 seconds, and starts again and again. If there is an emergency (the ambulance passes), apply for interruption, all four directions are red light, and then start again after 10 seconds. (further design, a number of digital tubes on the test box can be used to display countdown in two directions, or LED dot matrix display stop, Chinese character or animation).)
