the traffic light based on the single-chip control
Abstract
The intersections vehicle wears shuttle, pedestrian Xi Rang, garage driveway, person's sidewalk, orderly. So depend what to carry out this well arranged order? What to depend is a traffic sign light of automatic conductor system. The control method of the traffic sign light is a lot of. This design is mainly divided into five greatest molds a piece the electric circuit, clock of the importation control a control outside procedure inside the electric circuit, slice to cut over a control and shows electric circuit. Take single slice the machine IntelAT89 C51 of the serieses MSC-51s as a center spare part to design transportation light controller, carried out the AT89 C51's P's 0 people's constitution of the chips red, the function in bright time of green light, Huang2 Deng Ran2;For the sake of system stability the credibility adopted a 74 LS14 airtight trigger eliminate of machine chip to tremble electric circuit especially, avoided system because of importation the signal tremble movable property to living a mistake operation; The P 2 people who shows that time directly passes the AT89 C51 output, is driven LED figures a tube by the CD4511 to show red-light Ran bright time.
Key word:  The AT89 C51   LED show    transportation light
