单片机控制饮水机的硬件设计

Microcontroller hardware design fountains

介绍了DS18B20型数组温度传感器内部结构以及工作时序,并提出了以DS18B20和AT89C51为主要器件设计的数字温度计审计方案,该数字温度计的测温范围为-20℃～+110℃,精度误差在0.1以内,具有测温精度高,控制性能良好等特点。在此基础上设计了饮水机的温控系统,并且控制固态继电器SSR-10A对加热管进行加热,从而达到对温度的控制。

The internal temperature sensor array DS18B20 structure and timing of work and proposed to AT89C51 DS18B20 and the main device audit programs designed digital thermometer,digital thermometer in the temperature range from-20 ℃ to ＋110 ℃ accuracy error of 0.1 or less,with a high precision temperature measurement,control,good performance characteristics.On this basis,the temperature control system is designed drinking fountains,and control of solid-state relay SSR-10A of the heating pipe heating,so as to achieve temperature control.
