基于52单片机的智能粮仓火灾报警系统设计
<p>粮仓火灾事故会带来难以估量的经济损失,结合现有技术,设计低成本的“粮仓防火”系统显得十分必要且意义重大。现在很多火灾报警器都是为一些大型建筑而研发的,诸如“粮仓”这种关乎国计民生的重要场所的防火系统却略显陈旧。利用单片机技术,设计和研发一种低成本、高可靠性、具有较高效率的智能火灾报警系统具备可行性。本文以STC89C52单片机为核心设计了一种基于温度、烟雾检测的粮仓智能火灾报警系统。系统使用
基于单片机的管道泄漏检测报警系统的设计与实现
<p>本设计的管道泄漏检测和报警系统以AT89C51单片机为控制核心,采用压力传感器YYYL100实现对管道内的压力的检测,使用MQ-2可燃气体检测传感器检测管道外部的可燃气体浓度,并具有LCD1602液晶显示电路可以显示当前的管道压力值和可燃气体浓度值。同时用户可以通过按键设管道的压力报警和和可燃气体浓度报警值,当检测值超过报警值得时候通过蜂鸣器和LED指示灯进行声光报警。</p><p>The
播种机远程作业监控系统设计——基于光纤传输及以太网通讯技术
<p>随着农业自动化技术的不断发展,无人驾驶播种机被逐渐应用到农业生产中,由于其远程监测和控制技术还不成熟,还无法达到无人化作业的水平。为此,将光纤传输和以太网通信技术引入到了无人驾驶播种机监控系统的设计中,并以AT89S52单片机为控制核心,以太网模块作为接口,采用光纤作为传输媒介,利用摄像头和传感器采集现场速度数据及播种机的运行情况,实现了基于以太网的远程无人驾驶播种机的监测与控制。为了验证方
住宅防火报警系统设计
<p>这篇文章主要介绍了住户防火报警系统。以MCS-51系列的80C51为核心结构,当自动监测器监测到火灾时,可实现声光报警、故障诊断、浓度显示、报警上限设置、延时报警及串口通信,向单片机发出请求,再通过单片机控制相应的报警和驱动负载,实现自动防火报警功能。</p><p>This paper mainly introduces the household fire alarm system.Tak
