Study on Supply Chain Intelligent Design System of Foreign Trade Enterprises under the background of Internet

With the introduction of one belt, one road and the “Silk Road” strategy, and the deepening of supply side reform, the cross-border electricity supplier market in China has developed rapidly and has penetrated into key links such as production, circulation and services. In this paper, the complete experimental model is imported into unity 3D platform to complete the development of dynamic effect of three-dimensional experiment. Finally, the virtual experiment system is published in the form of web page. At the same time, this paper uses Quartus II to write FPGA, and completes the construction of hardware circuit. The hardware data transmission interface and the virtual data receiving port are set to complete the data transmission.
