Abstract: A development of distributed area traffic signal lights control based on single-chip microcontroller through CAN BUS is described. With the core of AT89C51, infrared receiver receives the infrared ing from launcher. The demodulation signal is treated by single-chip microcontroller. The single-chip microcontroller controls the CAN BUS controller to structure CAN munication system to transmit the data. The designator of distributed traffic signal lights intelligent control system was carried out by three control styles of Vehicle flux, remote and PC. The paper introduces total scheme and hardware design of the system in detail.
