GSM短消息在工程机械机群智能管理中的应用

Application of GSM SMS in the Intelligent Management of Construction Machinery Cluster

讨论了全球移动通讯系统(GSM)移动网络中定位和数据传输等功能在工程机械机群管理中的应用.介绍了基于信号到达时间差(TDOA)的位置估计技术,并对以递归迭代为特征的泰勒级数展开算法进行了讨论.在对比了几种数据传输技术后,给出了机群监控系统数据流量的算式以及基于 Matlab 的短消息收发编程.最后以一个沥青混凝土摊铺机群的例子介绍了 GSM 在工程机械智能管理中的应用.

This paper focuses on application of global system for mobile communication(GSM)to locate re- mote machines and transfer on-line data and signals between machines and console.TDOA-based locating technique is introduced,and an iterative location algorithm based on Taylor series expansion is discussed,After comparison of technologies in data transfer,a formula to reckon transmission capacity and MATLAB-based programs for SMS processing are presented.A case in machine cluster for asphalt mixture paving is studies.
