Tang Dong · Journal of Shanghai University of Electric Power · 2010
To meet the requirements of cutting accuracy for the steel enterprises by measuring the rectangular steel sheet on the basis of S7-300 PLC the design of the cutting accuracy verifying device for steel sheet is presented.The design can better fulfill the function of alerting and real-time monitoring,and perfectly realize the measurement of diagonal difference,height and oblique cutting rate.Main hardware,S7-300 PLC program structure design and algorithm model are also discussed in detail.Operation data of the scene indicates that operation of the system is stable and reliable,and easy to operate and maintain.
