1、III 交通灯控制器系统设计 学生:XXX 指导教师:XXX 内容摘要:随着当今世界经济的迅速发展,嵌入式系统在生活中的应用越来越广泛,也是生活中 随处可见的,同时嵌入式系统的发展也带动我国传统控制检测日新月异更新。在实时检测和自动控 制的嵌入式应用系统中,嵌入式技术已是一门核心技术,仅嵌入式方面的知识是还不够的,还应该 具备硬件结构,以及针对特定对象的软件相结合,加以完善。 十字路口的车辆不停穿梭,行人熙攘,车行车道,人行人道,有条不紊。那么靠什么来维持这 样的秩序呢?靠的就是交通信号灯的嵌入式系统设计。交通信号灯控制方式有很多。本系统采用 MSC-51 系列单片机 Intel8031 和可
2、编程并行 I/O 接口芯片 8255A 为中心器件来设计交通灯控制器, 实现了能根据实际车流量通过 8031 芯片的 P1 口设置红、绿灯燃亮时间的功能;显示时间直接通过 8255 的 PA、PB 口输出;交通灯信号通过 PC 口输出;交通灯的点亮采用 VT 双向晶闸管来控制,直 接采用 220V 交流电源驱动,系统实用性强、容易操作、功能性强。 关键词:嵌入式 交通灯 控制器 设计 实现 IV Traffic lighTraffic light controller system designt controller system design Abstract: Abstract: Wit

5、ely on to maintain this order? Rely on embedded system design of the traffic lights. Traffic lights control the way a lot. The system uses the MSC-51 series of microcontrollers the Intel8031 and programmable parallel I / O interface chip 8255A-centric devices to design a traffic light controller, ba
6、sed on actual traffic flow through the 8031 chip P1 outlet red, the green light to kindle time function; show directly through the 8255 PA, PB, port output; traffic light signal output port through the PC; traffic lights lit VT bidirectional control directly to a 220V AC power drive systems practical, easy to operate , functional and strong.
