With the development of social economy, the level of industrial productivity has gradually improved, and tobacco production has also ushered in the era of electric control automation production. For tobacco factories, the production efficiency of machinery and equipment is closely related to the tobacco production benefit. When the electrical control of equipment fails, it will also seriously affect the related production processes. To avoid this kind of problems, it is necessary to strengthen the equipment maintenance management, and take precautions against the problems related to electrical control to ensure the stable production of mechanical equipment. Based on this, according to the actual demand of tobacco production, combined with the operating principle of tobacco equipment, the common problems and countermeasures of electrical control of equipment were discussed in depth. 展开更多
