|
摘要
重点研究基于单片机绿植养护系统温度控制的方法,主要设计显示电路、温度采集电路、时钟电路、报警电路和控制调整电路。利用单片机控制温度传感器DS18B20采集温度数据,实现温度转化,采用1602液晶对温度进行实时显示,将温度保持在设定温度。通过按键调节温度报警区域(上下限值),实现对温度在一定范围内的自动监测(18~35℃)。经过反复测试证明该设计方案准确可行、运行可靠,温度偏差可控制在0.1℃以内。
This paper mainly studies based on single chip microcomputer green plant maintenance methods of temperature control system.Main design display circuit,the temperature acquisition circuit,clock circuit,alarm circuit and control circuit adjustment.Using single-chip microcomputer control temperature sensor DS18B20 collecting temperature data,Realize the temperature conversion,using 1602 liquid crystal display the temperature in real time,and keep temperature at the set temperature.Through the button adjust temperature alarm area( upper and lower limit),To realize automatic monitoring of temperature within a certain range( 18 ~ 35 ℃). After repeated tests proved the feasibility of the design scheme of accurate,reliable operation,Temperature deviation can be controlled within 0. 1 ℃.
