Microcontroller-based traffic light controller design and implementation of
Abstract: With the rapid development of science and technology in recent years, SCM applications are deepening at the same time promote the growing of traditional control detection technology updates. In real-time detection and automatic control of the microcomputer application system, the microcontroller is often used as a core component, only the microcontroller is not enough knowledge, but also based on specific hardware structure of hardware and software combination to be improved. Crossroads shuttle vehicles, pedestrians bustling, car dealers driveway, people walkways, methodical. Then rely on to achieve this discipline of the order of it? Is the traffic lights by the automatic control system. Traffic signal control many ways. The system uses this design uses a 74190 chip countdown control in each direction, connected with the two realized, also used the 74153 chip, because the time set Bottom of the analysis are five, so as long as 74,153 pairs of high position with a bit of the low initial pre-locked to 5, while the high is provided as needed by the feedback part of the preset values. Green time of traffic flow can be detected by a double-digit LED display. The system practical, simple, extending strong function.
