非接触式红外测温灶具防干烧系统设计
|
摘要
为防止锅具干烧引发灶具炸裂、火灾等重大安全问题,设计了一种灶具防干烧系统.该系统采用红外温度传感器MLX90614对锅具底部进行非接触式实时温度监测,实时温度数据由STM32单片机通过SMBus总线进行采集和处理.温度监控模块在锅底温度超出正常加热区间后会声音报警,达到干烧阈值温度后则通过串行接入灶具热电偶温度检测回路的控制电路切断燃气气路.实验结果表明,该系统能在达到预设温度时切断燃气气路,有效避免灶具干烧.
In order to prevent the serious safety problem caused by the dry pot burning and stove explosion and firing,an anti-overheating system was designed. The system of infrared temperature sensor MLX90614 on the bottom of the pot was used to realize the non-contact real-time temperature monitoring. The real-time temperature data was collected and processed by the STM32 microcontroller and SMBus. When the temperature of the bottom of the boiler was beyond the normal heating range,the temperature monitoring module could send a voice alarm. When the threshold value of the dry burning temperature was reached,the gas circuit could be cut off by the control circuit serially connected in the thermocouple temperature detection circuit. Experimental results showed that the proposed system could cut off the gas path once the preset temperature reached and prevent the dry pot burning effectively.
