Description

technical field [0001] The invention relates to an electric control system and a control method, in particular to an electric control system and a control method for a rail fine grinder. Background technique [0002] With the development of science and technology, the degree of automation of industrial control is getting higher and higher. An automation equipment or system is composed of mechanical components and a control system. A stable, reliable, safe and economical control system is an important factor to measure the quality of a piece of equipment or a system. Commonly used control methods include conventional relay control circuits, PLC (programmable logic controller) control systems and computer control systems. [0003] The existing electric control system of refiner usually adopts relay control circuit. The relay control circuit only has the control of a single drive device, and is mainly used for the control of simple devices. The principle is simple and the cos...
