城市道路上车流量不断增多,交通灯在维持安全有序的交通秩序上扮演着重要角色。为了保证交叉路口车量快速、安全通过,各种智能化的交通灯应运而生,基于LabV IEW的智能交通灯系统不但满足了上述条件,还有实时监控路况和方便维护、改善系统等优点。本文通过虚拟仪器软硬件结合实现十字路口红绿灯指示、绿灯倒计时、车流量检测等功能。
Increasing traffic flow on urban roads, traffic lights play an important role in maintaining a safe and orderly traffic order. In order to ensure fast and safe passage at intersections, a variety of intelligent traffic lights came into being. The intelligent traffic light system based on LabV IEW not only meets the above conditions, but also has the advantages of real-time monitoring of traffic conditions, convenient maintenance and system improvement. In this paper, through the combination of virtual instrument hardware and software to achieve traffic lights at the crossroads instructions, green light countdown, traffic flow detection and other functions.
