The invention discloses an electrical control system for a general assembly production line of a tractor, which comprises a PLC (Programmable Logic Controller) controller, a frequency changer, a sensor unit, an oil pump control switch, an oil cylinder control switch, a relay control unit, a running mode transfer switch and a conveyer belt drive motor for a production line, wherein the PLC controller is respectively connected with the frequency changer, the sensor unit, the oil pump control switch, the oil cylinder control switch, the relay control unit, the conveyer belt drive motor and the running mode transfer switch, and the frequency changer is connected with the conveyer belt drive motor. The invention also discloses an electrical control method for the general assembly production line of the tractor. The running and the accurate contraposition control on big-inertia mechanical systems can be realized by using the PLC controller as the control core of the electrical control system. The invention has the advantages of rapidness, accuracy, safety, reliability, good service performance and the like.
Description
technical field [0001] The invention relates to an electrical control system and a control method, in particular to an electrical control system and a control method used in a tractor assembly line. 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] Existing electrical control systems for tractor assembly lines usually use relay control circuits. The relay control circuit only has the control of a single drive device, and is mainly used for the control of simple devices. The princi...
