The invention provides a blowing-
carding electrical control system and a control method. The blowing-
carding electrical control system comprises a bale
plucker, an opener, a multi-bin cotton blending
machine, a scutcher, a cotton conveying pipeline, a
carding machine, a fan, a
metal-
fire detector, a dust removal
machine, sensors and a
control system and is characterized in that the
control system comprises a central controller and a human-
machine interface, the sensors comprise a bale
plucker traveling speed sensor, a picking depth sensor, cotton blending pipeline pressure sensors, cotton blending bin level sensors, a cotton blending machine inclined screen speed sensor, a cotton blending machine flat screen speed sensor and cotton conveying pipeline pressure sensors, the
signal output ends of the sensors are connected with the
signal input end of a central controllor, and the controllers of the bale
plucker, the opener, the multi-bin cotton blending machine and the scutcher are connected with the central controller respectively. The
automation control of the online detection and the real-time adjustment of the blowing-carding
system can be achieved, situations such as multi-bin useless running, overlarge fluctuation of cotton storage amount, unsteady rear stage cotton conveying and frequent
start stop can be avoided, and smooth cotton supply and continuous and even sheet cotton output can be guaranteed.
