End control system of dust collecting fan and transformation method of dust collecting system

The invention relates to the field of control of dust collecting fans, in particular to an end control system of a dust collecting fan and a transformation method of a dust collecting system. In orderto solve the problems of energy waste, high production cost, potential safety hazards and the like of existing dust collecting systems, the invention provides the end control system of the dust collecting fan. The system comprises a dust sensor, an air speed sensor, a speed regulator and an electric valve, wherein the dust sensor is arranged at the dust collecting opening to collect actual dust concentration m in real time at the dust collecting opening; the air speed sensor is arranged in a dust collecting pipeline to collect the actual air speed value in real time; the speed regulator is connected with an intelligent controller and the dust collecting fan; the electric valve is arranged in the dust collecting pipeline and is connected to the intelligent controller; and the intelligent controller automatically c
