伽马暴偏振仪1553B终端设计

Design of 1553B Remote Terminal in Gamma Ray Bursts Polarimeter

摘要: 设计了基于51系列单片机控制的1553B RT(Remote Terminal)终端系统，用于伽马暴偏振仪(POLAR)与卫星平台TG-2号之间的科学数据、工程数据以及遥控指令的传输。设计中采用BU-65170芯片作为RT终端系统的1553B协议芯片。通过设计1套基于1553B功能板卡的BC(Bus Controller)模拟器，测试了POLAR 1553B RT终端系统的数据通讯功能。测试结果表明，所设计的基于51系列单片机控制的1553B RT终端系统数据通讯稳定可靠。

Abstract: A set of 1553B remote terminal (RT) system was designed based on control of 51 series microcontroller. The system will be used for transmitting scientific data and housekeeping data from gamma ray bursts polarimeter (POLAR) to TG-2, and control instruction from TG-2 to POLAR. BU-65170 is used as 1553B protocol chip in the system. A set of 1553B bus controller (BC) simulator was designed in order to test the data communication function of 1553B RT system. The test result indicates that the data communication function of 1553B RT system based on control of 51 series microcontroller is stable and reliable.
