Traffic light simulation system designed by Series of 74 IC consists of four major components: second pulse generation unit circuit, display unit circuits, timing circuits and power supply unit cell circuit. Second pulse generation unit circuit high-precision frequency 32768Hz crystal oscillator for the timing circuit to provide frequency standards for the 1Hz pulse. Display unit in the timer circuit JK flip-flop timing pulse generated under the traffic lights were orderly control. Timing module circuit, realized the timing function, but also realized the time the digital output to control the function. The circuit power supply unit circuit to provide the required voltage. Using Altium Designer Winter09 plotting cell circuit and the overall circuit, with pulse unit Multisim2001 for second simulation, in the use of Proteus 7.4 for display units, regular units, and the overall circuit simulation. Through computer simulation software, has reached the design requirements, but I hope that in future designs to leak to fill a vacancy on the Traffic Light system expand and improve.Keywords Traffic lights, Second pulse,timing, Altium Designer, Proteus 目 录 TOC \o 1-
