【摘要】 环境保护已成为整个社会的共识。空气质量监测在我国国民经济可持续发展战略中发挥着重要的作用。本文介绍了基于C／S模式，结合Internet／Intranet技术的“太原市空气质量监测系统(AQMS)”的总体规划、网络结构模型设计、功能模块划分以及实现方法。 文章从规划一个可行的Client／Server系统的角度出发，对系统功能设计、系统前后台操作系统、后台数据库管理工具、前台应用程序开发工具以及硬件设备的选择给出详细论述，着重讲述了系统中远程数据调用的方法、通信程序开发工具的选择与使用、调制解调器与AT指令、系统中通信机制的规定以及利用MODEM基于RS232的中心站与子站实现数据通信的具体方法。更多还原

【Abstract】 Environment Conservation has been the common goal of the whole society. Air quality monitor can play a great role in our national economic persist-development. The article has introduced the whole layout ,model design of network , partition of function and realization methods of AQMS in TaiYuan , which based on Client/Server and combined with Internet/Intranet technology.The article discussed the function design , system OS of front and background, DB management tools on the background , application program developing tools on the stage and the selection of hardware device in order to mark out a feasible Client/Server system. The article emphasized on dissertation of long-distance data transfer method , selection and use of communication program developing tools , MODEM and AT instruction , prescript of communication rules in the system and the detailed method introduce using MODEM based on RS232 to realize data communication from central station to sect station.更多还原
