基于CPLD的智能多功能交通灯设计

Design of an Intelligent Multifunctional Traffic Light Based on CPLD

基于Altera公司的复杂可编程逻辑器件CPLD(Complex Programmable LogicDevice),采用硬件描述语言VHDL,外围电路以光电传感器为核心,在QUARTUSII7.2开发环境中设计了一种兼有数字钟功能的智能多功能交通灯,能实时检测道路车辆的排队情况,并进行流量统计.

A multi-function traffic light was designed based on CPLD of Altera, which was developed with VHDL in QUARTUSII7.2. A digital clock was also included in this design. The photoelectricity sensor was the most important part of the periphery circuit, which was used to detect the traffic status and the amount of vehicle.
