摘要： 在某型卫星地面电联试过程中,对该卫星的姿态轨道控制系统进行接口分析及信号统计,针对其接口复杂性、信号多样性的特点,提出采用片上系统(Systemona Chip,SOC)芯片对所有部件模拟器进行通用化设计。文中给出了该型卫星通用型电模拟器硬件平台设计方案以及陀螺、反作用轮和通用接口模块的硬件配置说明,针对该型卫星姿态轨道控制系统电联试要求,对所有部件按真实接口配置成电模拟器,形成通用接口箱、敏感器电模拟器箱和执行机构电模拟器箱,并通过CAN(Controller Area Network)总线接入闭环仿真,对太阳捕获、地球捕获及正常模式进行了仿真测试,仿真结果表明通用电模拟器满足设计要求,对其他卫星的地面电联试有很好的参考价值。

Abstract: The interfaces of Attitude and Orbit Control System (AOCS) were analyzed during the process of some satellite desktop electric integration tests.A design method of general-purpose electric simulator based on SOC (System-On-a-Chip) was proposed to solve the complex interfaces and multi-type signals.The satellite general-purpose electric simulator was designed and how to adapt it to configure the gyro electric simulator,wheel electric simulator was presented and a general control module was illustrated.According to the requirements of the AOCS desktop electric integration testing system,On-Board-Computer simulator,general interfaces box,sensor simulator and actuator simulator were configured.The simulators,communicating with other parts by CAN (Controller Area Network) bus,were used in the desktop electric integration testing system to simulate sun capture,earth capture and normal control modes.The results show that the general-purpose electric simulator meets the requirements and has reference value to the development of other electric simulators of satellite desktop electric integration testing system.
