摘要
设计了一种基于STM32F407的焦炉煤气氧含量在线分析仪。该分析仪采用数字型磁力机械式氧传感器PM1158进行氧含量的测量,它不仅能够测量常量氧,而且也能够用于微量氧的检测,测量精度高、响应速度快。传感器输出的信号经过信号采集电路及调理电路送入微处理器STM32F407中进行后续处理。实验结果表明,研制的焦炉煤气氧含量在线分析仪抗干扰能力强、稳定性好,完全符合工业现场的需求。
The online analyzer based on STM32F407 for oxygen content in coke oven gas is designed. The analyzer measures oxygen content with digital magnetic and mechanical type oxygen sensor PM1158. It can be used not only to measure the constant oxygen,but also to detect trace oxygen with the characteristics of high measurement accura-cy and fast response speed. The output sensor signal,passing through signal acquisition circuit and conditioning cir-cuit is sent to microprocessor STM32F407 for subsequent processing. The experimental results show that the coke oven gas oxygen content on-line analyzer can fully meet the needs of industrial field with strong anti-interference ability and good stability.
