摘要
采用单片机作为核心控制元件,对超声波传感器和红外传感器采集回来的信号滤波和分析计算;再转换成控制信号,经过放大驱动变换成可以控制电机转速的模拟信号控制汽车防撞以防追尾。其中采集的超声波信号经过核心电路、电源控制模块、检测反馈模块、电机驱动模块和液晶显示模块等模块,完成了对车距的检测;红外传感器采集和反馈的信号主要是车速的控制,防止车与车之间发生碰撞。同时,对车速智能控制系统进行了性能指标分析、可靠性设计、电路兼容性设计,并最终完成了整个电路的设计。试验结果表明,该装置性能可靠,分辨率高,控制准确,有效防止了车与车的相撞,保护了驾驶员的人身安全。
This design uses the single chip microcomputer as the core control components,the signal acquisition of ultrasonic sensor and infrared sensor were filtered,analyzed,calculated,and converted to a control signal. After amplification drive,the signal is converted into an analog signal to control the motor speed,to control the car crash to prevent rear-end collision. Where is the ultrasonic signal acquisition completed the detection distance from the vehicle through the core circuit,power control module detects feedback module,motor drive module and LCD modules and other modules. An infrared sensor collect the feedback signal and the vehicle speed is mainly controlled to prevent a collision between the car and the car. Meanwhile,the speed intelligent control system of performance is analysed,reliability and electromagnetic compatibility is designed,and finally completed the design of the entire circuit. The experimental results showed that the device performance was reliable,high resolution,accurate control,greatly prevent the car collided with the car to protect the driver's personal safety.
