Design of a cut tobacco volume flow detection system based on bulkscan lms511

Abstract

This paper mainly introduces the application of a cut tobacco volume flow detection system based on bulkscan lms511 in the tobacco industry. First, bulkscan lms511 identifies and marks the installation space location information through self-learning algorithm; Then, the cross-sectional feature information such as the height, width and angle of the conveyor belt is extracted and analyzed; Finally, according to the extracted characteristic information, combined with the encoder signal, the instantaneous / cumulative volume flow of conveying cut tobacco can be calculated, and then combined with the cut tobacco density value, the instantaneous / cumulative mass flow of cut tobacco can be calculated indirectly. The measurement error range is 1.11 %-1.48%, and the average error value is 1.29%. The detection system has the characteristics of high precision and high reliability. Based on this platform, more research topics can be carried out. For example, through the PID closed-loop control system to regulate the running speed of the bottom belt of the storage cabinet, it can indirectly control the flow of cut tobacco and improve the continuity and stability of the feed flow.
