Title Research and design of real-time detection of bulk material conveyor systems
Abstract
With the market requirement for the material measurement accuracy, the long-term weighing stability of high-precision belt scale become major problems, and belt running side is one of the key elements affecting the weighing stability, this article designs and develops a conveyor belt deviation detection system to improve weighing stability.
Based on the analysis of the current belt deviation detection system deficiencies and problems.I put foward a plan which is based in 51 chip
Microcomputer and priority encoder to Collection and Handle photoelectric sensors transmitted data.Then through the serial communication technology to connect with the PC.Using VB software to read and store transported data. There are two main methods and storage , datebase storage ande excel storage.At last,graphics will be demonstrated in PC.
Keywords phototriode; deviation; VB; Excel spreadsheet; storage;Serial communication
