针对航天器系统级测试中控制器局域网(CAN)总线测试设备通用化程度低、研制成本高、实时性难以保证的问题,设计了一种基于商用货架产品(COTS)的航天器 CAN 总线测试方案,可通过配置实现航天器CAN总线节点模拟、数据监视及处理等功能.经测试验证,该方案满足航天器系统级测试需求,可为后续航天器CAN总线测试设计提供参考.
CAN Bus Test Scheme for Spacecraft Based on COTS
In response to the problems of low general-purpose extent,high cost and difficulty in ensuring real-time performance of CAN bus test equipment in the spacecraft system level test,a spacecraft CAN bus test scheme based on commercial shelf products(COTS)is proposed which can achieve function of spacecraft CAN bus node simulating,data monitoring and processing by flexible configuration.It is proved that the test requirement of spacecraft can be satisfied by this scheme,which provides a reference for the subsequent design of spacecraft CAN bus test scheme.
