摘　　要：在介绍USB接口和RS485接口的基础上,分析了USB、RS485和AT89C52各自的特点提出一种旨在综合AT89C52、USB接口、RS485接口3方面优点的远程数据采集系统设计方案,并从硬件、软件结构两方面详细阐述了实现方法。最后指出该远程数据采集系统具有较强远程传送能力和使用方便、支持热插热拔、价格低廉、功能较强等优点,可用来实现分布式检测控制系统,具有广阔的应用前景。Based on the introduction of USB and RS485 interface, each characteristic of USB, RS485 and AT89C52 is analysed, a design scheme of long-distance data gather is put forward which integrates the advantages of USB, RS485 and AT89C52, and a particular description of implement method is given from hardware and software aspects. At last it points that the system have the advantages of strong long-distance carry ability, cheap and hot insertion, hot swapping. It can be used to implement distributed measure control system and has wide application foreground.
