【摘要】 目前,GPS定位信息的传输方式主要以GSM的SMS或电路交换方式进行,其缺点是实时性差、费用高、信息承载量小。电信部门推出的GPRS业务,具有实时性好,数据按流量收费且费用低廉等特点,这使得采用以GPRS为主、GSM为辅的定位信息传输方法代替单一的GSM传输方式成为新的发展趋势。文中详细介绍了将GPRS、GSMI、nternet、GIS、GPS等技术融为一体的远程监控系统的设计,并给出了移动终端具体应用实例。更多还原

【Abstract】 At present,the transfer of GPS were mainly implemented by the modes of SMS or circuit of GSM,of which the defects invlove poor charactor of real time,high expense and loading only a few information.The GPRS operation developed by telegraphic department has the characteristics of real time operation,obtaining the expenses according to the current of data and low costing,etc.Thus it has been a new trend that the unitary GSM transfer mode replaced by orientation transfer mode of whose GPRS for major and GSM for supplement.Chiefly describes the design of a remote supervision and control system combining the techniques of GPRS,GSM,INTERNET,GIS,GPS,etc.And the application of transfer ternianl was also presented.更多还原
