The invention belongs to the technical field of dust removal and discloses an intelligent electrical-automation dust removal control system and a method. The intelligent electrical-automation dust removal control system comprises a power supplying module, a smoke and dust detection module, a parameter input module, a main control module, a power regulation module, an air exhaust module, a filtering module, a fault detection module, a data storage module and a display module. According to the system and the method, a discharged dust concentration from a very low concentration, i.e., 0.01mg / kg to a high concentration, i.e., 50mg / kg or more can be measured by using an image sensor, i.e., a CCD or CMOS area array or linear array digital camera and a laser beam through the smoke and dust detection module, so that the requirements of online smoke and dust monitoring on ultralow discharging are met; and meanwhile, fault data fragments are mapped into image data through the fault detection module, and a data processing problem is changed into a fault recognition problem, so that the risk of information loss caused by direct preprocessing of the data is lowered, the fault recognition rate of a blower driftage system is increased, and meanwhile, visualized displaying is performed very vividly and lively.
