摘要
文章以车辆测距结果作为距离识别核心算法,以51系列单片机作为硬件平台,利用测距算法和嵌入式各自的优势,设计了一款非特定车、小距离、高精度的汽车防撞报警系统;在TMS320C6713DSK开发板上进行论证;实际系统前端采用超声波特征参数、并用中断程序与报警程序结合对其进行去噪后得到信息进行处理,并通过数码管显示单元模块显示两者之间的距离,然后通过蜂鸣器发出不同频率的声响;结果表明,该系统在满足系统实时性的同时也提高了其测准率,具有一定的实用性。
Based on vehicle distance measurement results as a core algorithm to identify distance with 51 series microcontroller as the hardware platform, using distance measuring algorithm and embedded tecnology, designed a specific ear, small distance, high precision of au- tomobile anti--collision warning system; Argument in TMS320C6713DSK development board; Actual system front--end using ultrasonic characteristic parameters, and interrupt program and alarm after denoising to get information for processing, and through digital tube display module display the distance between the two, and then through the buzzer sends out different frequencies of sound; Results show that the system at the same time satisfy the system real time to improve the measuring precision, has certain practicality.
