摘要
为了解决航天器供配电系统重量体积制约、提高有效载荷所占比重,采用以单片机为核心处理器,固态功率控制器(SSPC)为功率输出器件、RS422数据总线进行数据传输的小型化、智能化配电器设计方案,代替航天型号传统的继电器和断路器作为功率输出器件、硬线线缆传递控制指令的设计方案,实现航天器电气负载可靠供配电。该方案有效地减少航天器上仪器设备的重量体积,提高供配电系统的工作可靠性数据和传输速率,并且在故障隔离、浪涌抑制等电气系统重要功能上取得显著效果,对其他航天型号供配电系统设计具有借鉴意义。
To solve the problem of spacecraft power supply and distribution system weight and volume constraints,and to increase the proportion of effective load,using a miniaturization intelligent distribution solution which chooses single chip microcomputer（SCM）as the core processor,solid state power controller（SSPC）for power output devices,RS422 data bus to data transmitting.In place of the traditional design using relay and breaker as power output device and cable as Instruction transmission medium,the design realizes reliable power supply and distribution of electric load of spacecraft.It can not only effectively reduce the weight and volume of the instrument and equipment on the spacecraft,but also improve the working reliability and data transmission rate of power supply and distribution system,and achieved remarkable results in fault isolation,surge suppression and other important functions of the power supply and distribution system.It also has a referential significance to other spacecraft electrical system design.
