Aiming　at　the　problem　occurs　when　getting　the　distributed,　heterogeneous　and　dynamic　data　in　the　Engineering　Structure　Experiment,　this　paper　proposes　ESESGrid　(Engineering　Structure　Experiment　and　Simulation　Grid)　data　acquisition　system　which　based　on　self-adapting　MAS　(Multiple　Agent　System)　and　designs　the　registration　and　access　of　agent　based　on　WS-Management([1]).　In　addition,　owing　to　the　Time　Series　Characteristic　of　data　acquisition　in　ESESGrid　and　the　conflicts　when　resolving　questions　in　MAS　system,　the　self-adapting　negotiating　model　based　on　Time　Series　will　be　also　designed　and　discussed　in　this　paper.
