【摘要】 在电力系统铁路电网电参数监测系统中，我们采用了基于单片机A/D采样的新型无线通讯方式，成功地实现了远端20个监测点与本地主控室之间的数据传输。在该系统中，本文首先从理论上系统地讨论了通过GSM网络提供的远程业务一短消息服务SMS(Short Message Service)进行信息传输的特点与优点，并提出了将该技术应用于铁路电网电参数监测系统设计中的可能性与必然性，同时对系统中用到的无线通讯接口规范及标准进行了说明，这就为系统设计提供了充分的理论依据。 其次，在对系统性能作出具体分析的基础上，本文提出了一种基于GSM网络的系统设计方案，即利用Wavecom公司研制的WMOD2B手机Modem来实现远端监测点与主控室之间的无线架构。文章先从硬件与软件两方面入手，详细分析了20个远端监测点与主控室两大部分的系统设计方案，按着阐述了临测现场与主控室之间的数据通讯的实现过程，最后分析了系统开发过程中用到的提高系统可靠性的措施(包括各种单片机抗干扰措施和提高数据通讯可靠性的措施)。 总之，这种将无线通讯方式应用于电力系统铁路电网电参数临测系统中的设计思想是在诸如车辆调度、导航、监控、监测、监测等领域应用开发中的一种先进的设计手段与必然趋势，这也是本文的创新之处。同时在文章的最后，就系统开发中引发的问题作出了探讨，并对今后的应用前景作出了技术展望。更多还原

【Abstract】 This paper introduces the monitor and detector system of parameter in railroad electric power network which by utilizing wireless communication mode based on single-chip computer A/D sample,successfully achieves the data transmission between twenty remote monitor stations and central control unit.Above all,this paper systematically discusses the feature and advantage of message transmission by short message service which GSM provides as one remote work in theory.And at the same time,advances the possibility and necessity of the design scheme which put the SMS technology into the monitor and detector system of parameter in railroad electric power network,and makes comments on the wireless communication interface standards,so this provides sufficient theory evidence for the design of system.Secondiy,on the basis of analyzing the system characlerislics,this paper advances a design scheme based on GSM network,that is,by WMOD2B mobile telephone modem,the Wavccom company developed,to accomplish the wireless erection between remote monitor stations and central control unit.From the two aspects of hardware and software design,this paper analyzes the two parls’design scheme in details,and elaborates how to accomplish the data communication between the two parts.Finally,analyzes some measures improving the system reliability including several single-chip computer anti-interference measures and measures improving the reliability of data communication.All in one,this idea which puts the wireless communication mode into the monitor and detector system of parameter in railroad electric power network is an advanced means and certain trend ,such as in the field of vehicle-dispatching, navigation, monitor and detector.This is an importance and also uniqueness of this paper.By discussing some problems arised in the process of developing system, puts forward to technology foreground in the future.更多还原
