摘　　要：为实现智能仪器的远程控制,提高控制系统的速度,采用现场可编程门阵列(FPGA)芯片、USB芯片等实现了智能仪器远程控制系统的设计。重点介绍RS 232与USB的接口转换原理及FPGA程序设计和仿真。系统采用先入先出存储器和有限状态机实现了RS 232与USB的接口转换,并实现上位机的控制、数据处理等功能。系统可大大减少上位机的工作量,不仅可以用于实验室也可应用在工业生产中。In order to remotely control the intelligent instruments and improve the speed of the control system, a remote control system for intelligent instruments is designed based on FPGA and USB chips. The principle of the interface conversion between RS232 and UBS, as well as the design and simulation of FPGA are introduced emphatically. The interface conversion between RS232 and USB was achieved with FIFO memorizer and state machine. The functions of PC control and data processing was completed. It greatly reduces the workload of the PC, and can be used in the laboratory and industrial production.
