With the rapid development of science and technology in recent years,SCM applications are deepening at the same time promote more traditional control detection update.In real-time detection and control of the microcomputer application system,the microcontroller is often used as a core component,only the SCM knowledge is not enough,should be based on specific hardware architecture hardware and software,to be perfect.
Crossroads shuttle vehicles,pedestrians bustling,car dealers Drive,people walkways,orderly.Then rely on to achieve the discipline of the order then?Rely on the automatic traffic light is the chain of command.Many ways to control traffic lights.In this system,MSC-51 Series MCU ATSC51 and programmable parallel I / O interface chip 8255A-centered design of traffic signal controller device to realize the actual traffic volume by 8051 according to the P1 port chip set of red,green time kindle function; traffic light cycle of light,countdown 5 seconds left when the yellow light flashing warning (traffic lights signal output port through the PA,indicating time directly through the 8255's PC port to double-digit output of the digital control); vehicle ran a red light alarm; green time can detect vehicles flow can be by double-digit digital display.The system practical,simple,powerful extensions.
