Abstract
To ensure the safety of car reversing,a sound and light alarm device is installed inside the car to provide safety reminders based on the actual environment when reversing.This paper designs an infrared reflective reverse top speed sound and light alarm circuit,which consists of infrared emission,infrared reception,signal processing,comparison output,alarm indication and other components.The military grade SE555 oscillator is used to transmit infrared signals,while the industrial grade LM224 operational amplifier is used to amplify and compare circuits,achieving sound and light alarm functions.The test results show that the circuit has stable performance,high reliability,sensitive response,and can achieve high-speed alarm.关键词
