摘要
为了检测水体中矿物油和动植物油的含量,进而判断水质污染情况,在红外分光光度法的基础上,研制了一种基于STM32处理器的红外分光测油仪。该仪器利用STM32自带的A/D转换器和USB数据传输功能,结合高精度热释电偶传感器和信号处理模块,实现了吸光度、浓度的自动计算和标准曲线的绘制,操作简单、准确度高、符合国家标准。
In order to evaluate the situation of water pollution,we should detect the content of mineral oil and animal-vegetable oils,and then judge the situation of water pollution in water.According to infrared spectrophotometry,an infrared spectralcolorimetry spectrometer based on STM32 processor is developed.Combining with high-precision pyroelectric sensor and signal processing module,and with built-in A/D converter and USB data interface,the instrument achieves automatic calculation of absorbance and concentration.And it provides the function of drawing standard curve.Test shows that it is of high accuracy and simple to operate.
