As　an　extension　and　expansion　of　the　Internet,　the　Internet　of　Things　(IoT)　has　the　characteristics　of　＂comprehensive　perception,　seamless　interconnection,　highly　intelligent＂,　and　is　regarded　as　the　third　wave　of　information　technology.　The　Internet　of　Things　gateway　is　located　between　the　perceptual　network　and　the　telecom　network,　and　realizes　information　exchange　and　communication　among　heterogeneous　networks.　It　is　the　key　network　element　device　that　promotes　the　development　of　Internet　of　Things　technology.　In　this　paper,　aiming　at　the　problems　of　single　function　and　poor　scalability　of　traditional　environmental　data　acquisition　system,　we　designed　an　intelligent　environmental　gateway　platform.　The　gateway　platform　uses　ARM　+　FPGA　architecture　based　on　Zynq-7000　All　Programmable　SoC　(AP　SoC),　uses　PetaLinux　which　is　designed　specifically　for　FPGA-based　system-on-chip　as　the　Embedded　Linux　Development　Kit,　and　utilizes　4G　LTE　communication　technology　to　report　real-time　environmental　data　to　remote　service　platform.　The　experimental　results　show　that　the　system　is　stable,　reliable　and　scalable,　and　the　software　and　hardware　have　achieved　the　desired　effect　and　function.
