Design and implementation of intelligent traffic lights control
based on MCU
Abstract
In recent years along with the rapid development of science and technology, SCM
applications are continually deepening, and promote the traditional control detection
technology is updated. In real-time detection and automatic control of the microcomputer
application system， the microcontroller is often used as a core component ， only SCM
knowledge is not enough, should be based on specific hardware structure of hardware and
software combination, to be perfect.
Crossroads shuttle vehicles， pedestrians bustling, car dealership traffic lane， people
walkways， everything in good order and well arranged. So what to rely on to realize it in
order？ Is the traffic lights on the automatic command system. A lot of traffic signal control。
This system uses STC89C52RC and 74HC245 system and the smallest transistor driving
circuit and a periphery of the keys and digital tube display and other parts， a design based
on the single chip design of traffic lights。 Design through one of two common cathode nixie
tube display, and can be key to regular set。 This system is practical， simple operation，
strong expanding function。
