【Abstract】 This paper briefly introduces the design of PLC automatic control system. Through analyzing the dust removing system by using fabric bags in steel making, it proposes two measures, namely setting the anecdotal rate and standard of temperature, to increase the responding speed of the system. And it turns out that they are efficient ways.更多还原
