摘要
介绍了面向空间科学实验应用背景的高可靠控制器的解决方案。该方案利用MSP430与IGLOO系列FPGA的低功耗模式,设计了一种新型的温备份方法,在保证系统高可靠性的前提下依然能够达到较低的功耗,并确保科学实验在单路控制电路失效的情况下能够不中断实验进程。该控制器具有高可靠、低功耗以及接口资源丰富的特点,可以满足各类空间科学实验的需求,并已应用于空间有效载荷集成支持系统项目中。
This paper introduces the design of highly reliable controller for space science experiments. By taking advantage of the low-power modes of MSP430 and IGL00 FPGA, a new warm sparing method is developed in order to maintain high reliability with low power consumption, and to ensure experiment continuity in case of single control circuit failure. The controller has high reliability, low power consumption and varieties of interfaces, which make it perfect in different kinds of space science experiments. This design is adopted in the project space payload integrated support system.
