Abstract: With the development of social, scientific and technological progress, as well as people's living standards gradually improved, a variety of convenient living in the automatic control system into people's lives, to the core of the single-chip systems are more and more. At the same time in the field of automatic control is also a sign of the digital age has become a member. It is practical, full-featured, advanced technology, to make people believe that this is the progress of science and technology. It made human beings understand that the development of the digital age will change the lives of human beings, will accelerate the development of science and technology. The design for the crossroads traffic lights control system design, hardware to its 8031 MCU core, and on that basis to expand the program memory (EPROM) 2764, static RAM (SRAM) 6264, addresses the use of latches 74LS373 expansion I / O parallel interface chip 8255A. It combines some of the software from time to time / knowledge to carry out procedures such as the count compiled.
