With the rapid development of modern building materials industry , concrete block making equipment intelligent seem important . Domestic and international technology gap is quite large . Concrete block making equipment in China is not high degree of automation , the noise , the high failure rate . Imports of concrete block making equipment , but its price is expensive , so the domestic intelligent concrete block molding equipment demand is particularly urgent . Thus the domestic market is an urgent need to develop an intelligent , low- cost , superior performance concrete block making automated production line equipment . QT9-15 concrete block molding automated production line for the study and analysis of the concrete block molding production process and control requirements based integrated use of advanced control technology , system integration technology , remote service technology , reliability, design technology , developed a set of concrete block making production line system . Make a certain contribution for the realization of concrete forming intelligent automated production line . This paper focuses on the structural layout and process QT9-15 concrete block making automated production line , production line controller and PLC module selection, control system reliability design , the PLC key program design , production line monitoring program development of the touch screen , between PC and the lower machine communication mechanism , enterprise-class host computer program design of key technologies . Paper by means of WPLsoft ScreenEditor , C # 2.0 , database and other software , the completion of the concrete block forming automatic production line PLC control program design , process control level touch screen program design , host computer software system 's design and development , to achieve a whole production line field level control , process level control , enterprise-class control and monitoring of remote fault diagnosis and maintenance functions .
