Method and device for detecting wind powder proportion and flow rate with ultraviolet light source process

The invention discloses a method and a device for detecting wind powder proportion and flow rate with an ultraviolet light source process. An ultraviolet emitter and an ultraviolet receiver are arranged at centers of two sides of a pipe through which a wind powder mixture flows respectively; a sensor of the ultraviolet receiver adopts an ultraviolet photoresistor, and the resistance value of the photoresistor is converted into a voltage signal; a data processor performs direct signal sampling and digital filtering on the voltage signal, ultraviolet radiation intensity and the coal powder movement characteristic are obtained, the ultraviolet radiation intensity is converted into the wind powder proportion according to the relation curve between the wind powder proportion and the ultraviolet radiation intensity, and the coal powder movement characteristic is converted into a wind speed according to the relation curve between the coal powder movement characteristic and the wind speed.
