In　recent　years,　with　the　development　of　embedded　systems,　industrial　control　systems　have　higher　requirements　for　visualization.　Data　obtained　by　sensors　are　not　only　huge　in　quantity　but　also　with　fast　updating　frequency.　Therefore,　how　to　analyze　and　integrate　effective　data　to　provide　to　users　has　become　an　urgent　problem　to　be　solved.　This　paper　introduces　a　Online　Float　Glass　Defect　Marking　Management　System　based　on　PIC18F97J60　MCU　and　Xilinx　XC7Z020CSG484C1　FPGA　chip　as　the　control　core,　using　Omron　nb7w-tw00b　Touch　Display　panel.　The　system　is　connected　to　the　upper　Glass　Defect　Detection　System　through　the　Ethernet　network,　receives　the　defect　coordinates　transmitted　by　the　upper　system　and　marks　them　on　the　glass,　and　communicate　with　the　touch　Display　Panel　uses　MODBUS　protocol,　realizing　the　visualization　of　the　whole　system.　©　2019　ACM.
