| 为了扩大“北斗”一代终端的应用范围，降低使用成本，提出了一种多SIM卡复用的“北斗
”
终端设计方案。采用FPGA+ARM的硬件结构，将SIM卡增加至多张，通过软件设计实现数据自
动分片和多张SIM卡的协同工作，提高“北斗”终端的数据传输速率。该方法已成功运用于
野外
油气井远程监控系统中。 |

| Abstract: |
| In order to expand the application scope and reduce the cost of
the first generation Beidou terminals, this paper proposes a Beidou terminal des
i
gn scheme using multi-SIM cards multiplexing. This design scheme uses FPGA + ARM
hardware architecture, increases the number of SIM cards, and realizes data aut
omat
ic fragmentation and collaborative work of the multi-SIM cards through
software design, thus enhancing the data transmission rate of the Beidou termin
al. This method has been successfully deployed in Oil and Gas Well Remote Monito
ring System in the field. |
