航天地面测试中1553B-PCI接口转换技术实现

One Conversion Technology between 1553B and PCI Bus in Space-Ground Testing Field

为实现有效载荷地面测试过程中终端设备与星上1553B总线上被测试设备之间的信息交互,需要应用1553B总线到计算机标准接口的通信板卡。本文通过对1553B总线和PCI总线协议的分析,结合航天地面测试实际要求提出了一种1553B-PCI总线接口卡的实现方法,给出了硬件结构框图,部分原理图和接口控制的FPGA实现。经过测试,实现了计算机通过PCI总线与远程终端设备的信息交互,满足了实际要求,并在XXX型号地面测试中应用。

In order to communicate between terminal devices and avionics which are connected with 1553B bus during satellite payload testing field, communication board from 1553B to standard peripherals interface is needed. In this paper, through studying 1553B bus and PCI bus protocol, one conversation technology between 1553B and PCI bus in space-ground testing filed is presented. The paper put forward hardware diagram, partial principle and interface FPGA realization. Through test, the board can realize communication between remote terminal device and computer with PCI bus and has been used in XXX satellite ground testing filed.
