摘要
设计了一种用于冶金、化工、材料、生物发酵等会自发热环境的液体温度控制系统。系统以单片机为核心,温度检测使用DS18B20,DAC0832与三菱FR-F740系列通用变频器为驱动单元,通过控制水泵流速改变被控对象温度,具备声光报警和显示功能。经过验证表明系统温度控制精度达到预期设计目标,有较高的控制精度。
A liquid temperature control system for self-heating environments such as metallurgy,chemical engineering,materials,and biological fermentation was designed.The system is based on Single-Chip Microcomputer.The temperature detection uses the DS18B20,DAC0832 and Mitsubishi FR-F740 series general-purpose inverters as the drive unit,which changes the temperature of the controlled object by controlling the flow rate of the pump,and includes the sound and light alarm and display functions.Experiments show that the system temperature control accuracy meets the expected design goals and has high control accuracy.
