Design Of Automatic Control System For Concrete Block Molding Production Line Based On PLC

In recent years,with the rapid development of China's real estate industry,the demand for concrete block molding equipment is getting larger and larger.Concrete block molding equipment not only has a huge market development prospects at home,but also meets China ' s basic national conditions and the needs of social development.Due to the low degree of automation,easy to malfunctions,inconvenient repair and low productionefficiency of self-developed concrete block molding equipment,it cannot meet the needs of the market at present stage of our country.The key technology of block molding automation technologyof our country is locked up byother countries,whose products are expensive to sell abroad.Therefore,our markets need to develop a high degree of automation,low cost,superior performance,with our own independent intellectual property rights of concrete block molding automatic production line equipment.This thesis has competed the design of the control system of concrete block molding production line program and hardware control circuit through analyzing the production process of concrete block molding and the specific control requirements.The whole process is supported by Panasonic series PLC,inverter,servo driver,servo motor,sensor and other hardware together with modern control technology,system integration technology and reliability technology.Then the monitoring of control system,the adjustment of dynamic parameter,the settings of process parameters,the communication of upper computer and lower computer and other functions are achieved through the configuration software and touch screen technology.Afterwards,this thesis has made a thorough introduction to PID controller and a simulation analyze.Finally,the system control scheme is optimized,the stability of the system and the accuracy of the simulation are verified by means of mathematical modeling and Simulink simulation on the batching system and the vibrating platform of concrete block molding.The design of concrete block molding production line control system is feasible and reliable,and can meet the requirements of site production,On our own brand of block forming the development of production lines are a certain reference value.
