摘　　要：介绍以USB 2.0为通信接口的反重力铸造充型过程测试系统的设计与实现。本系统采用Cypress公司的支持USB2.0高速传输的EZ-USB FX2系列器件CY7C68013A作为主控制器,搭建外围数据采集电路,实现采集数据的快速传输。与以标准串行接口为通信接口的方法相比,本系统数据传输速率高,实时性强,精确性高。This paper describes the design and implementation of the communication interface of the anti-gravity casting mould filling process test system based on USB 2.0. The system uses Cypress＇ s EZ-USB FX2 series devices CY7C68013A as the main controller which support USB 2.0 high-speed transmission, to construct peripheral data acquisition circuit structures for fast trans- mission of data collection. And compared to the communication interface methods using standard serial interface, the system has advantages of high data transfer rate, real-time and high accuracy.Test System of Anti-gravity Casting Mould Filling Process Based on USB 2.0 Interface YANG Hui, YU Zi-rong, CHEN Li-juan, CAI Peng-xiang （ School of Information Engineering, Nanchang Kangkong University, Nanchang 330063, China） Abstract： This paper describes the design and implementation of the communication interface of the anti-gravity casting mould filling process test system based on USB 2.0.
