The invention provides an intelligent self-adaptive tensioning
system and method for a
belt conveyor under a mine. The
system comprises a belt
assembly, a tension detection unit, an
intelligent control unit and an execution mechanism which form a closed-
loop control system. The tension detection unit monitors the belt tension in real time and outputs a
signal; the
intelligent control unit receives the
processing signal, calculates an adjustment amount according to a self-
adaptive control algorithm and generates an instruction; and the execution mechanism receives the instruction to adjust the belt tension. A
fuzzy PID (
Proportion Integration Differentiation)
control algorithm is adopted, a tension prediction model is included, and a tension adjusting
assembly can be accurately adjusted. The method comprises the steps of tension detection,
data transmission, preprocessing, working condition recognition and
target setting, tension prediction, control quantity calculation, instruction generation and execution, closed-loop feedback,
safety monitoring and the like. Real-time accurate automatic adjustment is achieved, frequent manual intervention is not needed, complex working conditions can be dealt with, the belt problem is avoided, the production efficiency is improved, the service life of equipment is prolonged, and the operation performance is optimized.
