In order to realize the full automation of the ultrahigh strength automobile panel strip removal production line,a full automatic high strength automobile panel strip removal production line was designed by taking the strip stripping of steel coil at the entrance of galvanizing production line as the control object and studying the production process.The composition and working flow of production line,the design methods of the electrical control system and software system were described in detail.In view of the complexity and variability of the site,the intelligent diagnosis expert system was established for various faults those may appeared in the production process;Bayesian discriminant method was used for intelligent diagnosis and alarm.The practice shows that the average stripping time of the designed production line is 3.3 min less than that of the traditional manual stripping time,which improves the production efficiency and has high practical application value;the onsite safety record shows that the intelligent diagnosis expert system operates normally and has no error in alarm,which provides guarantee for timely handling of equipment faults and safe production.
