从单片机的基础上探讨输送带运输的自动化设计
<p>现阶段以来,煤矿运输事故发生主要是因为技术与设备等条件制约而导致的,事故发生的次数还在不断的增加,从而给矿井生产水平带来了不良的影响。其中输送机作为主要的生产设备,值得深入研究。基于这样输送带的情况,笔者作了进一步的深入研究探讨。本文从带式输送机的结构原理出发,阐述了输送带自动化的意义,并且探究了单片式芯片的自动化输送带系统应用。</p><p>Since the present stage,
基于PIC16F873单片机的汽车自适应巡航控制系统的研究
<p>当前,汽车工业快速发展,随着消费者对汽车生产技术要求的不断提升,汽车的生产技术含量也成为行业研究的重点内容之一,就汽车的内部设计技术来说,巡航控制系统是其重要技术组成部分,汽车的巡航控制一般是在一定的车速范围内,在汽车遭遇外力干扰的情况下,驾驶员可以不控制加速踏板,系统借助自动调节气门开度实现对于发动机转矩的有效调节,保证汽车按照设定的车速实现恒速行驶。这一控制系统的设计对于汽车车速稳定性,
基于单片机的自行车码表设计
<p>自行车不仅仅是低碳生活的代步工具,而且成为国民体质锻炼与娱乐休闲的重要工具,因此,随着越来越多的骑行者数量的增加,而装在自行车上的码表就应该是骑行者应该具备的装备之一。本自行车码表设计以STC89C51作为CPU主控芯片,在LCD1602芯片上显示行驶速度,里程等各种信息,利用霍尔传感器来实现脉冲信号的输出作为外部中断信号,利用语音播报提示,并且用DS1302获取日期数据,还有蜂鸣器超限报警
基于单片机的跌倒检测报警系统设计
<p>当代社会,老年人群健康安全监护的需求日益增加,老年人跌倒检测的研究成为社会关注热点。故文章设计了一种基于单片机的跌倒检测报警系统,选用STC89C52单片机作为控制芯片、ADXL345传感器作为检测模块以及GSM发送装置作为通信模块。首先,利用检测模块采集老人日常活动中的运动数据,经模数转换后将其发送给单片机,以判断老年人当前状态。当满足触发条件时,报警模块发出声音提醒老人和周围的人,并将求
速度与挡位匹配提醒系统的研究与设计
<p>近年来,交通运输已成为我们生活中比较重要的一部分,私家车及驾驶员的数量均越来越多。本文针对这种情况,为驾驶员,尤其是初学者提供一套手动挡汽车速度与挡位匹配的控制系统。此系统以单片机为控制核心,结合监测、控制、显示、语音播报ISD4004、报警等模块实现行车过程的实时监测、控制及提醒。本系统为初学者提供辅助教学,为驾驶员提供经济的行车方式,同时提高我国的汽车行业的竞争力。</p><p>In r
一种车辆入库自动循迹停车系统的方案设计
<p>汽车在现代社会生活中的普及程度越来越高,对停车环境和效率的要求也越来越高,先进的自动停车系统可以大大缩短停车的时间,提高停车位的利用率。本设计是一种在车库中应用的能够实现停车路线自动规划的系统,车辆进入车库就自动循迹并引导停车。该系统主要由环境数据采集子系统,中央控制子系统和车辆行驶姿态控制子系统组成。其中车辆行驶姿态控制子系统主要涵盖路线生成与自动循迹等;环境数据收集子系统包括信号接收和传
