The intersections vehicle wear shuttle, pedestrian Xi Rang, garage driveway, persons sidewalk, orderly.So depend what come to realization this well arranged order?Depend of be the auto of the traffic sign light conductor system.The control way of the traffic sign light is a lot of.The machine 8051 of this system adoption series MSC-51 list slice with programmable proceed together the I/O pick up a people the chip 8255 AN is center spare part to design transportation light controller, realization ability according to actual the car discharge pass the P of 8051 chips 1 people constitution red, the green light Ran be bright time of function;Traffic lights circulation the point be bright, while remaining 5 while pouring to account Huang2 Deng flicker caution;(transportation light the signal pass a PA output, manifestation time direct pass 8255 of PC output to double figures tube)The vehicle run the red light to report to the police;Time of the green light can examination car discharg
