【 摘 要 】

The paper is devoted to the vision system for determining the grain-size distribution of finely crushed particles (∼ 0.1mm in size) of bulk material moving on a conveyor belt. A block diagram of the system and data exchange protocol are presented. The commands for high-speed LED pulse backlight control are provided. The functional diagram and principle of the LED matrix control are described. The results of a full-scale testing of the system at the mining and processing plant are presented. As a result of the full-scale testing of the system at the mining and processing plant, the absolute error varies from 1.2% for the class "+ 4.0mm" to 5.2% for the class "-0.1mm". The absolute error for the target "+ 1.0mm" is 2.5%.
