一种星载电源系统下位机设计

摘要

为了增强对新一代星载蓄电池的管理，设计一套多功能的电源系统下位机变得有重要意义。在此论述了一种电源下位机的设计方案，它以MCS⁃51微处理器系统为核心，通过软硬件相结合，针对蓄电池的特性，合理制定了蓄电池的充放电管理策略。实践结果表明，电源下位机的技术方案可行，能有效地对蓄电池进行控制，大大提升了星载蓄电池的工作寿命与可靠性。%In order to strengthen management of the new generation satellite ⁃ borne battery, it is significant to de⁃sign a suite of multifunctional slave computer that is proper for power system. A design scheme of slave computer power system is described in this paper. It takes MCS⁃51 microprocessor as its control core. In combination with software and hardware, the charge and discharge management strategy of the battery was drawn up according to the characteristics of the batteries. Prac⁃tical application effect shows that the design is rational and feasible,can control the batteries effectively,and improve the working life and reliability of satellite⁃borneies.
