【摘要】 工程机械是各项基础设施建设所必需的施工机械装备。“十五”期间,随着我国国民经济加大基础设施的投入,工程机械行业进入了高速发展阶段。在这种背景下,利用信息技术实现工程机械生产、管理与售后服务的远程信息交流势在必行,研究工程机械远程监控系统具有十分重要的实际意义。本文针对国内外工程机械远程监控系统发展的现状和存在的问题,提出了一种工程机械远程监控系统的三层结构模型:单元控制器、车载前端监控系统和远程监控系统,并重点围绕其中的远程监控系统进行研究与开发。首先介绍了GPRS网络结构及特点并制定了监控中心与车载监控终端的通信协议;其次利用Winsock提供的“套接字I/O模型”,在Windows平台下完成高性能的基于TCP/IP的通信服务器;在监控中心的数据库系统中采用三层C/S(服务器/客户机)模式,更方便地实现了多用户进行远程监控,不仅提高了系统的整体性能,而且使系统维护和升级变得更简单;最后,利用MapInfo公司提供的GIS二次开发组件MapX开发出客户端软件,很好的实现了对移动式工程机械实时远程监控和定位。本文研发的远程监控中心管理系统已经在实验室与车载监控系统中底层的安全监控装置和中间层的车载前端监控系统进行了模拟联调,实验结果表明,该系统人机界面友好,使用操作方便,且具有通信正确、稳定可靠、速度可以达到实际应用的要求等特点,验证了本文所研发的成果的有效性和实用价值。更多还原

【Abstract】 Construction machinery is the essential construction equipment used in the construction of infrastructural facilities. During the period of China’s Tenth Five-year Plan, with the increase of the national investment in the infrastructure field, the construction machinery trade enters into a fast developing stage.Under these circumstances, it is imperative to use information technology to perform the long-distance information interchange for production, management and after-sale services of mechanical equipment. Therefore it is of great practical significance to study the remote monitoring system in construction machinery.Aiming at the development actualities and problems of construction machinery monitoring systems in China and abroad, this thesis brings out the three-layer model of construction machinery monitoring system: Unit controller, machine-used forepart monitoring system and remote monitoring system.And, priority carries out research comparing with develop around remote monitoring system. Have introduced the GPRS network structure and the characteristic first and have worked out the communication agreement monitoring centre and machine-used supervisory control terminal; Make use of "Socket I/O model " TCP/IP-based communication server accomplishing high-performance under platform in Windows that Winsock provides secondly; Have adopt three layers of C/S (server/ customer machine) pattern in Database monitoring centre , have come true more convenient multi-user carry out long-range supervisory control, not only have improved the systematic overall function, and messenger system upkeep and promotion become simpler; Finally, GIS which provides using MapInfo Corporation two developments modules MapX develops customer end software, the very good realization to moved the type project machinery real-time long-distance monitoring and the localization.At present, the center has been experimented with other subsystems and machine-used monitoring system in the laboratory. The result shows that the center has advantages like friendly man-machine conversation interface, convenient debugging and maintenance, high reliability, correct communications, a high communication speed to achieve the requirement of its applications, which also confirms the validity and application value of the present research results.更多还原
