摘　　要：通过对目前信标机的应用范围及国内外的发展状况进行研究,设计了一种基于两路GPS信息接收和切换的无线信标机。控制电路采用C8051F040单片机作为主控芯片,控制两路GPS模块的切换从而增加无线信标机的工作时间,提高定位精度并降低功耗。实验测得UTC时间为11:37:30,北纬38.013 6°,东经112.446°,海拔高度为815.9 m。多次测量结果表明,该系统能实现定位数据的接收与转发并将定位信息通过上位机进行显示。Through the research of the application and development of the current beacon on the domestic and international,a kind of radio beacon was designed based on two GPS information received and switching. The switching control circuit uses C8051F040 chip as the main chip to control two-way GPS module thus for increasing the wirless beacon working time,improve accuracy and reduce power consumption. Experimentally measured the UTC time 11：37： 30,latitude 38. 013 6° east,longitude 112. 446,altitude of 815. 9 meters. The results showed that the system can achieve and receive location information and display through the PC.
