Particle sizing of coal mine dust by pattern recognition of laser diffraction

摘要

Particle sizing by laser diffraction provides a prospective method for real-time detection of weight and size information of coal mine dust. Quickness, accuracy and ability to measure total and respirable dust weights are some of the basic requirements for inversion method of the coal mine dust transducer. This paper presents a quick inversion scheme that can be referred to as pattern recognition of laser diffraction field. Single-chip computer system simulation results show that this method not only furnishes excellent estimates of both total and respirable dust weights in a very short time but also features high anti-noise ability and stability.
