一种基于串口终端+超短波电台的通联模型设计

A Connected Model Based on the Serial Port Terminal and Ultra-short Wave Radio

为了满足运输车、加油车、急救车等配发数量较大且单装价值较低的保障平台北斗导航终端一机多用使用需求,在传统“网口终端+超短波电台”通联模型的基础上,提出了一种基于“串口终端+超短波电台”的通联模型,并进一步设计了相应的串口NAT协议。在不改变上层指控应用使用习惯的条件下,有效解决了串口终端网络路由寻址和指控名录寻址难的问题。

In order to meet the multi-purpose needs of a large number of low-value security platforms,such as the transporter,the refueling truck and the ambulance,for the Beidou navigation terminal,a connected model based on the serial port terminal and ultra-short wave radio is proposed on the basis of the traditional connected model with the network port terminal and ultra-short wave radio,and the corresponding serial port NAT protocol is further designed.Without the changes of the using habits of high-level command and control applications,the difficulties of the network route addressing and the command and control directories addressing are effectively solved.
