摘要
基于三星S3F9454MCU和NTC热敏电阻研制了电热水壶电子式温控器,对热敏电阻温度传感器放置位置进行了优化设计,实测了220 V±10%电压、不同水量时的水温、热敏电阻的温度、发热盘上热敏电阻安装处的温度的变化曲线,得出三者温度之间的相互关系作为MCU数据处理的依据,给出了系统软件设计框图。经实践检验,该样机性能指标达到了设计要求。
Abstract: Based on Sanxing^s S3F9454MCU and NTC thermistor, the electronic temperature controller was developed for electrical kettle. We optimized the set place of thermistor temperature sensor,to meas- ure the variable curves of water temperature, thermistor temperature and the various pasition tempeerature of thermistor placed on heat plate under 220 V(ck 10~) for different water capacity. The mutual relation from these three temperature curves was provided as basis for MCU data processing. The flow diagram of system software design was given. This device has met the design requirement through practice testing.
