摘要
为了克服徕卡GMX902系列接收机只有串口短距离数据传输的缺陷,实现徕卡GMX902远距离传输GPS信号的目的,使其可以在野外恶劣无人坏境中实时存储GPS信号数据,并且控制中心可以远距离调控GMX902,文中提出了一种基于ARM-Linux的GPS信号存储转发系统的设计方案,并完成了系统的软件设计和整套硬件测试。长时间的综合测试数据表明,该系统能准确实时地将GPS信号存储到ARM板并转发给控制中心的上位机,实现了远距离调控和数据传输,系统性能稳定且容易操作,达到了系统设计要求。
In order to overcome the defect that Leica GMX902 series software receiver can only transmit data in short distance, achieve the purpose of Leica GMX902 remote transmitting GPS signal, make it can real-time storage GPS signal data in the field and unmanned environment under bad weather, and the control center can remote control GMX902, put forward a design scheme of GPS signal storage and retransmission system based on ARM-Linux, and complete the system software design and a complete set of hardware test. Long time integration test data shows that the system can accurately real-time store GPS signal to ARM board and transmit to GPS signal analysis software of the computer in the control center, realizes remote control and data transmission, the system performance is stable and easy to operate, meet the system design requirements.
