The paper primarily studies opc and windows dna - m , and develops a control opcda based on opc to realize data acquisition . following windows dna - m and applying opcda , the paper builds a distributed platform and applies it to information monitoring for a modular production system 本文重点研究了opc技术和windowsdna - m体系；成功开发了基于opc技术的数据采集控件opcda ；遵循windowsdna - m ，应用opcda控件构建了分布式制造信息监视平台，并将它应用于mps ( modularproductionsystem )系统状态监视中。
The computer mainly realizes the functions of long - range supervision and management and it includes : real time data communication , running state monitoring , history data save and print , error alarm , etc ; the industry computer system mainly compulish data acquisition and signal setting during the experiment and finish data storage and management ; the plc control system mainly accomplishes the on - off input and output , it accomplishes timing control , checks the status and carries the over - voltage and over - current protection ; except for acquiring experiment data , intelligent control instruments also have the function of errors diagnose and communication 上位计算机的任务是实现远程监测和管理，主要进行实时数据通信、运行状态监视、历史数据存储与打印、故障报警等；下位工业控制计算机主要用于实验数据采集和参数预置； plc控制系统主要完成开关量和部分模拟量的输入输出，实现系统运行的时序控制状态巡检和过载保护；智能监控仪器除获取现场参数外，还具有故障之诊断和通信功能。
As concerned as functions , the software can provide the following functions such as storage integration , storage sharing , disaster recovery , performance watch , status watch , data replication and central management , etc . the software was designed and implemented according to a perfect set of software engineering specification 该系统具有十分丰富的功能：存储整合、存储共享、灾难恢复、数据复制、性能监视、状态监视和集中式管理等。由于该系统的设计与实现是在一整套成熟的软件工程规范指导下完成的，因此，具有稳定、健壮、可维护性好等优点。
In accordance with practical network environment , we design and implement fault management system fms based on snmp . using client / server architecture , our system established a distributed management model which is compose of console / manager / agent , finished network status monitoring , event processing , fault alarm and log , collecting and analysing mib variable , etc . , provided many utilities about detection and browsing 系统采用了客户服务器结构，建立了由控制台管理者代理构成的分布式管理模型，完成了状态监视、事件处理、故障报警和日志、 mib变量的获取和分析等多项功能，提供了关于检测和浏览的有关工具。
