摘要
传统的星载计算机集成控制技术不能满足微小卫星日益复杂的数据交互要求和通用化、平台化的要求;研究了星上公共总线结构下的微小卫星控制结构,把星上网络划分为信息网和控制网;基于FPGA(Field Programmable Gate Array)芯片设计了星务计算机节点及其CAN(Control Area Bus)总线接口;应用了SOPC可编程片上系统技术,使得系统的体积功耗更小,提高了系统灵活性和功能集成度;通过微小卫星飞轮执行机构的控制实验,验证了基于总线的微小卫星控制系统的有效性。
Traditional satellite control system is integrated into an on-board central computer.However,this method can not satisfy micro satellite's increasing data interacting requirement and it can not produce standard modules to reuse.Architecture of control system based on public bus in micro satellite is presented.Buses are divided into communication bus and control bus.Satellite Keeping Operator(SKO) and its CAN bus interface are implemented using FPGA.SOPC(System On Programmable Chip) technology decreases the system's volume and power consumption,increases its performance and flexibility.An experiment to control a micro satellite's flywheel is performed.Experimental result validates the efficiency of the CAN bus-based control system.
