Automatic foundry production line control system and control method

Abstract

The invention provides an automatic foundry production line control system and a control method. The automatic foundry production line control system includes a plurality of sand-flushing machines, aplurality of conveyors, a casting train, a plurality of travelling crane, a main PLC, a plurality of travelling crane PLCs and a plurality of field PLCs, the main PLC is connected with the travellingcrane PLCs and the field PLCs, the travelling crane PLCs are in control connection with the travelling cranes in a one-to-one correspondence mode, the field PLCs are in control connection with the sand-flushing machines, the conveyors and the casting train in a one-to-one correspondence mode, the main PLC, the travelling crane PLCs and the field PLCs are in communication through an optical fiber ring network, a token ring network is further adopted to control communciation, and the main PLC, the travelling crane PLCs and the field PLCs are connected into the token ring network. Based on technologies of the optical fiber ring network and the token ring network, the three-layer same-grade PLCs are adopted, hierarchical and decentralized control is realized, the enterprise cost is lowered, and operation control is easier; and an optical fiber ring network framework is adopted, the reliability and the instantaneity of the networks are guaranteed, and operation is convenient and quick.

Description

technical field [0001] The invention relates to the field of casting, in particular to an automatic casting production line control system and a control method. Background technique [0002] The cost of the existing DCS / FCS system is high, it needs to be equipped with professional operators who are on duty 24 hours a day, and the requirements for the professional level of the operators are high, thus increasing the labor cost of the enterprise, and the product quality is affected by subjective factors in the manual operation process, and at the same time Many on-site application environments do not have the ability to apply the above systems, and their applicability is poor. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention provides an automatic casting production line control system and control method. [0004] To achieve the above object, the present invention adopts the following technical solutions: [0005] An auto...
