摘　　要：8051系列单片机在卫星上的应用非常广泛,在基于8051单片机的软件中,中断服务程序往往发挥着关键作用;这里对8051中断系统进行了介绍,并结合具体实例阐述了基于8051单片机的星载软件中断服务程序的设计方法,重点从中断寄存器初始化、中断响应、中断处理、中断返回等几个方面介绍了进行中断服务程序设计时的注意事项和一些经验体会;这些方法和经验已在多台星载设备上应用,具有一定的应用价值。The series of 8051 singlechip have been widely used on satellites. In the software based on 8051 singlechip, the interrupt service routine （ISR） always perform important tasks. The interrupt system of 8051 singlechip is introduced, the method of ISR design for onboard software based on 8051 singlechip is also be described which combined with some examples. Furthermore, the thesis describes a lot of experience and notice on ISR design of onboard software in interrupt register initialization, interrupt response, interrupt dispose and interrupt return. These ideas have been practiced on several onboard equipments, and have a certain extent application value.
