With　the　development　of　communication　technology　and　computer　network,　data　collection　and　processing　have　become　an　important　part　of　data　communications,　which　are　widely　used　in　digital　communication　and　control.　Traditional　data　collection　and　processing　uses　a　microcontroller　or　DSP　as　the　CPU　to　make　sure　the　implementation.　In　this　way,　the　data　processing　is　limited　by　machine　cycles　and　processing　speed,　which　cannot　meet　the　requirements　of　real　time　and　synchronization.　For　that　reason　we　propose　the　attempt　of　multi-sensor　access　by　using　FPGA　that　can　be　reset　and　is　full　of　system　building　flexibility.　Our　research　is　based　on　XILINX＇s　Spartan3A-DSP-1800＇s　FPGA　development　board　and　adopts　modular　design　that　lets　different　IP　cores　assigned　to　crossover　module,　temperature　and　humidity　sensor　module,　counter　module,　pressure　sensor　module　and　communication　module　respectively　to　implement　the　construction　of　system　on　chip,　improve　the　system＇s　flexibility　and　stability　and　greatly　simplify　the　circuit.　©　2011　IEEE.
