摘　　要：利用RS-485总线高速远距离传输抗干扰能力强、多点互联的特点,实现传统地衡测试仪的升级换代,发挥集中管理、分散控制的优势。以AT89S52应用系统作为下位机,完成具体测控任务;计算机作为管理级,对系统进行全面监控和管理。引入RS-485总线的分布式测控系统,简化了传统测控系统结构,既便于维护和提高工作效率,又为信息化建设奠定良好基础,该方法在工业测控领域具有广泛的应用价值。By adopting the features of RS-485 bus, i.e. high anti-interference capability in high speed and long distance transmission and multripie points intereonnection, the upgrade of traditional weigh-bridge testing instrument is implemented for elaborating the superiority of centralized management and distributed control. With AT89S52 application system as the slave computer, specific tasks of measurement and control are completed; and PC as the managing station, overall monitoring and management of the system are achieved. Introducing RS-485 bus into distributed monitoring system, the structure of the traditional system has been simplified. It brings easy maintenance and high efficiency; and builds excellent foundation to inforumtion construction. The method is worth to be extended in industrial monitoring area.
