The working principle of the belt conveyor and the loss principle are analyzed, and the PSO-BP optimization algorithm is designed to dynamically search for the optimal flux, so that the minimum input active power of the head/tail motor of the belt conveyor is globally optimal and the copper and iron losses are the lowest. The belt conveyor vector frequency conversion speed control scheme with the TMS320LF2407A DSP chip as the core is designed to realize the PSO-BP optimization algorithm. The hardware and software design of the scheme is completed. The optimization test of belt conveyor light load operation efficiency is designed, and the change curves of motor electromagnetic torque, rotor flux, input power and speed data are analyzed when the conveyor is started, and the load changed suddenly. The test results show that the scheme can improve the belt conveyor operating efficiency when the belt conveyor is lightly loaded, and quickly find the best solution to optimize the motor efficiency and ensure the efficient and stable operation of the belt conveyor.
