摘要: 针对传统光学法检测粉尘浓度时易受环境温度、光源和光电器件等因素影响的问题，提出了一种红外差分粉尘浓度测量方法，并基于该方法设计了一种粉尘浓度测量装置。该装置利用红外差分测量原理，通过以S3C2440为核心的数据采集与处理模块计算粉尘浓度，并通过LabVIEW信号处理模块对采集信号进行小波阈值去噪处理。调试结果表明，该装置具有较高的粉尘浓度信号采集精度和测量准确性。

Abstract: For the problem that traditional optical methods for measuring dust concentration were susceptible to environmental temperature, light source and photoelectric device, a dust concentration measuring method using infrared difference method was proposed, and a dust concentration measuring device was designed which was based on the method. The device calculates dust concentration by a data acquisition and processing module which takes S3C2440 as a core and based on infrared differential measuring principle, and uses wavelet threshold denoising method to process the acquired signals by LabVIEW signal processing module. The debugging result shows that the device is high in signal acquisition precision and measurement accuracy of dust concentration.
