摘要
针对基于定时控制的行人过街信号系统的通行效率较低及行人过街安全性较差的问题,设计了一种新型的智能行人过街信号系统,系统由主副控制器协调控制实现,两控制器均基于红外测距传感器阵列和超声波测距传感器,两种传感器分别用于识别灯柱下等待过街的行人与斑马线上的行人.详细阐述了系统软硬件设计原理和制作全过程,重点分析了采用相机进行视觉识别行人的弊端,并用仿真分析了智能过街信号系统与传统过街信号系统相比较的效果.
In order to solve the problem that low traffic efficiency and poor pedestrian crossing safety of the pedestrian crossing signal system based on timing control, we can design a new type of intelligent pe- destrian signal system. The system is controlled by the master and slave controller. The two controllers are based on infrared distance sensor and ultrasonic distance sensor, and the former is used to identify pedestri- ans under the lamp post, the latter is used to identify pedestrians on the zebra crossing. The design principle and the whole process of the system software and hardware are described in detail in this paper, and analysis is focus on drawbacks of using cameras to identify the pedestrians, and this system is compared with the tra- ditional street crossing signal system with simulation.
