The Electrical Parameters Of Railway Grid Based On The Gsm Network Monitoring System

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.
