Design of Intelligent Temperature Control System Based on Time-varying
摘要
为了最大化节省室内供暖能源
设计了一种分时段温度智能控制系统.该系统以微处理器AT89S8252为核心
采用DS18B20数值温度传感器实现对室温的数据采集
用液晶显示器显示温度和当前设定时间
并通过RS485将温度数据传送给上位机.当室温低于设置温度时控制器自行启动
电热器加热至设定的温度值.当室内达到设置温度时
控制器能自动断开电热器的电源.与传统的方法相比
该温度控制器可以设置多个时间段和不同的温度值
采用分时段控制技术
温度控制精度小于1℃
达到节约室内供暖能源的目的.
Abstract
An intelligent temperature control system according to period of time was presented to maximize saving the heating energy. The intelligent temperature control system with the microprocessor as the kernel is designed. The indoor temperature measurement used the DS18B20 temperature sensor and transferred to PC by RS485 communication bus
the temperature data and time setting displayed on LCD( Liquid Crystal Display) monitor.When the indoor temperature is lower than the setting temperature value
the electric heater was automatically turned on
and the indoor temperature is high than the setting temperature value
the power of electric heater was turned off by controller. Comparing with traditional method
this temperature control system can set up multiple periods and different temperature
meanwhile
the time- varying algorithm of temperature control is adopted
the precision of temperature control is 1°C and meet the demand of heating energy saving.
