Design and Analysis of Control Circuit for Danger Alarm Light and Turn Light of Vehicle Based on Multisim

In order to the solving interference between the danger alarm light and the turn light, intelligent control circuit of dangerous alarm light and turn light is designed, and the composition and principle of the circuit are analyzed. The characteristics of Multisim software are introduced. The resistance value and flashing frequency are calculated. The simulation of control circuit is conduced using Multisim software. The simulation results show that the circuit can realize the normal run of dangerous alarm light and the turn light separately, at the same time, when the danger alarm light is turned on, the turn light switch is also turned on, and the steering information can be normally indicated, thereby the interference problem of the two is solved when they are opened at the same time. The circuit has simple structure, strong practicability and strong application value.
