基于光学的无动力粉尘浓度检测技术

Non-power Dust Concentration Detection Technology Based on Optics

  • 摘要: 现有粉尘浓度检测技术采用主动抽取的方式,功耗高、测量结果容易受环境因素影响。基于光学散射法的无动力粉尘浓度检测技术,设计了特有的光学检测机构,通过建立二维风速补偿算法模型,应用粉尘浓度PID自适应控制算法,实现了粉尘浓度传感器的低功耗、大量程、高精度、高可靠性。实验结果表明,无动力粉尘浓度检测技术有效克服了主动抽取式检测技术的缺点,提高了粉尘浓度检测精度。

     

    Abstract: The existing dust concentration detection technology adopts the active extraction method, its power consumption is high and the measurement result is easily influenced by the environmental factors. The non-power dust concentration detection technology based on the optical scattering method was designed with a unique optical detection mechanism, and by setting up a 2D wind speed compensation algorithm mode and using the PID adaptive control algorithm of dust concentration, the low power consumption, large range, high precision and high reliability of the dust concentration sensor were achieved. The experimental results showed that the non-power dust concentration detection technology effectively overcame the disadvantages of the existing active extraction dust detection technology and improved the dust concentration detection accuracy.
