This system uses MSC-51 series monolithic integrated circuit ATSC51 and programmable parallel I/O connection chip 8255A is the central component designs the traffic light controller, realized has been able to act according to the actual traffic flow magnitude to establish, the green light through 8051 chip P1 mouths to burn the bright time red the function; The traffic light circulation lightens, the countdown remains when 5 seconds yellow light twinkle caution (traffic light signal through PA mouth output, tell time directly through 8255 PC mouth output to two-position nixietube); The vehicles run a red light the warning; The green time may examine the traffic flow magnitude and may through the two-position nixietube demonstration. This system usability is strong, simplicity of operator, extended function.
