航天员手动控制系统可作为自动控制和地面处置的备份手段.为了提高航天员在载人航天器驻留期间应对设备故障和突发事件的处置能力,采用系统工程方法对航天员手动控制系统进行了设计.通过地面试验测试,证明该手动控制系统设计能够有效地降低设备故障以及突发事件给航天员安全带来的风险.%The manual control system serves as the backup for the automatic control and the ground treatment in case of emergency. To help astronaut dealing with fault and emergency situations in orbit, a manual control system is designed based on the philosophy of systems engineering. The ground simulation and test show that the manual system can reduce the system risk for astronaut in case of hardware failure and emergencies in the orbit.
