With the analysis and arrangement of the whole information system of a painting workshop,the practical application of the information system were summarized(including MES,ANDON,PMC,AVI,etc.),the help of information control to the actual production were analyzed.The first,the field visual management was realized,through the MES,PMC,AVI system and the RFID information on the car body to interact with each other,to realize the real-time online tracking of the car body flow.The second,the field collection of production and quality information were used to connect the network for two-way data transmission,to realize the real-time production data interaction and quality of information,which can further improve the overall production quality visualization and reduce the Labor intensity,improve body quality and promote lean production to lay a solid foundation for the production of competitive products.
