烟尘浓度检测装置的设计

Design of Detecting Device for Dust Concentration

为了更有效地测量环境中的烟尘浓度,监测和改善空气质量,利用光电技术将尘粒浓度转换为成比例的电信号,以16位SPCE061A凌阳单片机为控制核心,设计实现了对烟雾浓度的检测,并给出了单元模块设计电路和配套的软件流程图。该装置可检测锅炉、工业、汽车尾气等污染源的烟尘浓度,并能进行连续监测,实现超值报警。实验表明,该装置烟尘浓度检测精度为0.1%,稳定性高。

In order to measure the dust concentration more effectively in the environment,to facilitate monitoring and improving air quality.Designed a method using optical sensors is proportional to dust concentration is converted to electrical signals,to Sunplus 16-bit MCU SPCE061A detection device for the control of the core.This device can smoke concentration,and the unit module and supporting the software design flow chart of the circuit are given.The device can be used to detect the boiler,industrial,automobile exhaust and other sources of dust concentration,both for continuous monitoring.Experiments show that the device shows dust concentration detection accuracy of 0.1%,stable and high performance.
