串口数据记录器的应用

雷达链路中最重要的部分是数据处理单元,在他的输出端包含点迹和航迹的一串特定格式的数据流。最常见的格式是ASTERIX,一些雷达使用另外的格式,如:RDIF、EC、SVE、AIRCAT、CD,等。如果想分析这些数据,必须首先记录并转换为可以被RASS软件工具现实和分析的统一的格式。通常这些数据放在串行链路上,以便他们需要被传送到一个或多个远处的控制中心。这个串行链路使用一些列如DHLC、LAPB或X.25的协议。其他格式S所使用专用协议,如13-bit 格式CD。

记录这些数据,RASS提供了2解决方案:

  • UDR600(USB Data Recorde)USB 记录器提供了2个串行通路。如果需要更多的通路,可以叠加使用多个UDR600。方位和时间(GPS450)的附加输入使其成为一个真正的雷达评估工具。作用:例如可以允许评估外部延迟。UDR600的记录数据可以被转换为一个适当的数据格式,供接下来的评估使用:可以是一个被SASS-C兼容的格式或RASS-S的数据格式。而且,应为了完整的通讯协议连同雷达数据一起被记录,可以分析链路质量和通信协议语法。
  • RDR803(Radar Data Recorder)雷达数据记录器提供了6路传行通路。RDR803是一个可以安装在ATC中心的便携的19英寸的设备,他配有多个雷达数据输入通道。通过USB集线器可以连接多个RDR803进而将串行通道扩展到6、12、18、24甚至更多。RDR803的记录可用于后期回放,以及在RASS-S、RASS-R(RC)或用于第三方工具(例如SASS-C)中进一步评估,或在RASS-R(Trackan)中连续监视使用。

SPECIFICATIONS
Interfaces/external Connectors
The UDR600 has two high-speed serial communication channels for passive recording.
The RDR803 has 3 pairs of twin high-speed serial communications channels for passive recording. Each of the channels can be confi gured individually. They can handle transmission speeds up to 128 Kb/s. Two electrical standards are supported: RS232 (single ended) and RS422 (differential). The serial data is fed to the recorder using two DB15 connectors (alike X.21 connections). The unit is supplied with two (UDR600) or six (RDR803) RS232 Probe modules for connection of the DB15 to a DB25 standard RS232 connection. A whole range of protocols is supported, and other can be programmed upon request.
