摘要

针对无缝钢轨远程监控系统中存在的无线通信费用较高的问题

对数据压缩的基本理论和GSM(global system for mobile communications)数据传输过程进行了研究

并结合该铁路无缝钢轨的数据特点

提出了一种数据压缩与GSM短信传输相结合的方法.采用对测得数据进行预处理、压缩BCD(Binary Coded Decimal)编码并进行有选择传输的方法组成了数据压缩系统

并将压缩后的数据应用GSM短消息进行无线传输.通过对无缝钢轨数据的仿真压缩验证表明

经压缩后的实验数据得到了大于80.6%的压缩比

达到了减少传输数据量

降低无线通信成本的目的.

Abstract

The basic theories of data compression and GSM Data transmission are studied to resolve the problem of high expense of wireless communication in remote monitoring system of seamless rail.A new method of data compression and GSM Data transmission is proposed by applying the data characteristics of seamless rail.To compose a data compression system

the measured data is processed by preprocessing

compressed BCD encoding and selected transmitting procedures.After that

we transmit the compressed data...
