Lithium battery powder conveying monitoring method based on water-sensitive material negative-pressure dilute-phase pneumatic conveying system

The invention provides a lithium battery powder conveying monitoring method based on a water-sensitive material negative-pressure dilute-phase pneumatic conveying system. The method comprises the steps that dilute-phase pneumatic conveying state parameters are obtained; closed pipe conveying conversion treatment is conducted on the dilute-phase pneumatic conveying state parameter and a preset conveying state parameter, and a dilute-phase pneumatic closed pipe conveying difference component is obtained; and a pumping on-off signal is sent to a negative pressure pumping controller according to the dilute-phase pneumatic closed pipe transmission difference. After the dilute-phase pneumatic conveying state parameters are collected, the current conveying condition of the negative-pressure roots vacuum pump is determined, and then the dilute-phase pneumatic conveying state parameters are compared with the standard conveying state parameters, so that the difference between the current conveying state and the standar
