摘　　要：电源分系统是卫星最重要的分系统之一,电源控制器(PCU)又是电源分系统的控制核心,为了解决PCU下位机模块前期软件开发调试无硬件的问题,设计并实现一种软件标准化硬件开发平台。该平台选用现场可编辑门阵列(FPGA)作为核心控制器,搭配现有型号常用的驱动电路,整合PCU常用的1553B、CAN和RS422通信方式,实现在PCU下位机模块硬件未到位之前,下位机软件已提前在标准化开发平台上完成开发和验证。实际应用表明,该平台能够适配不同型号的任务需求,降低人员开发的成本,提高软件开发的效率。The power subsystem is one of the most important subsystems of the satellite, while the power conditioning unit(PCU) is the control core of the power subsystem. In order to solve the problem of no hardware in the early software development and debugging of the PCU lower computer module, a software standardizationand hardware development platform. The platform selects FPGA as the core controller, matches the commonly used drive circuits of existing models,and integrates the 1553B, CAN and RS422 communication methods commonly used for PCU, so that the lower computer software has been developed and verified on the software standardization development platform ahead of timebefore the hardware of the lower computer module of PCU is in place. The practical application shows that the platform can adapt to the task requirements of different models, reduce the cost of personnel development, and help improve the efficiency of software development.
