基于Internet的远程故障诊断系统的研究与设计

Study and Design of a Remote Fault Diagnostic System Based on Internet

介绍了一种基于Internet的远程故障诊断系统的远程客户终端。远程客户终端由远程客户终端计算机和以AT89C52单片机为核心设计的智能数据采集卡组成。使用了由AT命令集控制的MODEM调制解调技术,通过公用电话网实现了实时远程数据采集、处理及管理功能。系统由远程故障诊断中心服务器、数据库服务器、远程客户终端组成。远程智能诊断中心通过广域范围内共享诊断资源平台,为客户提供共享资源和多种智能诊断手段,并能与客户进行交互。

The front terminal of a remote fault diagnositic system based on the Internet was introduced, lhe front terminal consists of a local computer and a intelligent data acquiring card designed on microcomputer AT89C52. The system, with the techniques of modem controlled by AT orders, can acquire and manage data from remote spots in real time via public telephone network. The system is made up of remote faults diagnosis sever, database server and remote client terminal. Remote faults diagnosis center provides shared resource and several intellective diagnostic methods, communicates with clients making use of large-scale shared resource.
