Design of Night Traffic Lights at Special Intersections Based on STM32
In some old urban areas,there are no overpasses in front of schools,kindergartens,hospitals,and some other institutions,only pedestrian crossings are set up.In order to ensure traffic efficiency,such intersections are usually not equipped with traffic lights,which poses a safety hazard for nighttime traffic.Therefore,it is necessary to design traffic lights for such intersections.Using the STM32 microcontroller as the core device for circuit design,the"button triggering"concept is adopted to divide the traffic lights into"normal state"and"switching state".Keil MDK software is used for pro-gramming,and the logic design for the two states is carried out separately.Finally,the simulation software,Proteus,is used to verify the effectiveness of the design.
