Concrete Block Making Automated Production Line Control System Development

As China's effort to increase the wall materials innovation policy, the dominant position of clay brick in the housing construction materials will be broken by concrete segmen, which will advance the development of China's construction industry and make a significant contribution to environmental protection. Since the majority of China-made Block Forming Machine is not high degree of automation, low production efficiency, and import of Block Forming Machine is expensive. An economical and good degree of the automation block machine production line is urgent need in Chinese market.QT10-15 Block Production line was chosed for the object of study in this dissertation. Distributed Control System was developed based on PLC, Frequency Control, Configuration Software, other industrial hardware and software platform after analyzed the production process and control requirements. For achieved information's integration and ensuring the system reliabler running, the Control Products of Detal's communication technology, the Block Machine hydraulic PID control, precise positioning Finger Cars, stack control, the control plate movements of key technologies were put emphasis on research. The PLC control procedures and monitoring procedures for the PC and HMI were developed based on the completion of the WPLsoft, ScreenEdit and VB development tool, which realized process control, information integration, process parameters setting, historical data management and intelligent fault alarm, and other functions.Debugging at the scene indicated that: The design of the Block production line control system achieve the expected functional requirements, has good reliability and availability to meet the requirements of production at the scene.
