1、摘摘要要 本系统是基于单片机的水暖锅炉控制, 在设计中主要有水位检测、 温度检测、 压力检测、按键控制、水温控制、水位控制、循环控制、压力控制、显示部分、 故障报警等几部分组成来实现供暖控制。主要用水位传感器检测水位,用数字温 度传感器 DS18B20 来检测水温,用五个控制按键来实现按健控制,用三位 LED 显 示器来完成显示部分,用变频器来控制循环泵的转速,用压力传感器检测锅炉内 部压力。并且通过模数转换把这些信号送入单片机中。把这些信号与单片机中内 部设定的值相比,以判断单片机是否需要进行相应的操作,即是否需要打开鼓风 机,是否需要开启补水泵,是否需要加快循环泵的转速等操作,从而实现单片
2、机 自动控制的目的。本设计用单片机控制易于实现锅炉供暖、而且有造价低、程序 易于调试、一部分出现故障不会影响其他部分的工作、维修方便、等优点。 关键词:关键词: 单片机(AT89C51),传感器,水位,温度,循环,自动控制 Based SCM design of heating boiler controlled syetemBased SCM design of heating boiler controlled syetem Abstract:Abstract:The systemic design bases controller of CMS water heating of a bo
