文档介绍：超声波倒车雷达摘要随着我国经济飞速发展,越来越多的人拥有了自己的汽车,同时由泊车和倒车所引发的事故也越来越多。这些事故常常给驾驶员带来许多的麻烦,因此,有助于驾驶员泊车和倒车的倒车雷达应运而生。倒车雷达全称叫“倒车防撞雷达”,也叫“泊车辅助装置”,是汽车泊车安全辅助装置,能以声音或者更为直观的显示告知驾驶员周围障碍物的情况,解除了驾驶员泊车和启动车俩时前后左右探视所引起的困扰,并帮助驾驶员扫除视野的死角和视线模糊的缺陷。本文介绍了以AT89S52单片机为核心的一种低成本、高精度、微型化,并有数字显示和声光报警功能的倒车雷达系统,该倒车雷达根据超声波测距原理研制,采用温度补偿技术、开机自检技术和优化的软硬件技术,将测得的结果送至数码管显示,同时进行三级声光报警。驾驶员只需坐在驾驶室就能做到心里有数,极大的提高了泊车和倒车时的安全和效率。关键词:倒车雷达、超声波、单片机AT89S52英语翻译:AbstractWiththerapiddevelopmentofChina'seconomy,moreandmorepeoplehavetheirowncar,,therefore,"reversinganti-collisionradar,"alsoknownas"parkingaids"isasafecarparkingassistdevice,capableofvoiceoramoreintuitivedisplayofobstaclesaroundthesituationtoldthedrivertoliftthedriverbothparkingandstartthecararound,whentheproblemscausedbythevisitandtohelpthedrivertoremovethedead,-cost,uracy,miniaturization,andadigitaldisplayandsoundandlightalarmfunctionparkingsensorsystem,reversingradar,theprincipleofultrasonicdistancemeasurementbasedonthedevelopment,pensation,thebootself-testhardwareandsoftwaretechnologyandoptimizationtechnology,themeasuredresultssenttothedigitaldisplay,:reversingradar,ultrasound,MCUAT89S52目录引言…………………………………………………………………--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
