基于1553B总线的星载相机地面检测程序通用化设计

1553B总线是一种时分制指令/响应式多路传输数据总线，广泛应用于飞机、舰船和卫星的通信中。目前已有部分星载相机采用1553B总线进行通信，但其命令多样，数据的传输类型也不尽相同，因此，卫星在地面检测时要根据对应的协议进行测试，必要时须对程序进行重新设计、修改，工作量较大。为了解决协议频繁更改带来的测试可靠性问题，文章基于VC编程技术，借鉴程序通用化的设计思想，实现了星载相机1553B总线通信检测程序接口的通用化设计，使地面测试程序得到统一化、通用化，提高了产品的开发效率和可靠性。

A Design of Universal Ground Checkout Program for Spaceborne Camera Based on 1553B Bus

Bus 1553B, a digital internal time division command/response multiplex data bus, has been widely applied in communications for airplanes, warships and satellites. Now some spaceborne cameras use 1553B Bus for communication as well. Different cameras have different commands and different data transmission types, so the ground checkout program for each camera needs redesign and modification according to related protocol. In order to adapt to the frequent protocol changes, by using VC programming technology and univer-sal design thought, the paper realizes a design of generalized checkout program interface for spaceborne camera based on 1553B Bus, which makes the ground checkout program unified and generalized and imoprove the ef-ficiency and reliability of the checkout.
