| 摘 要： | 地面与飞船之间的话音通信是载人航天通信系统的关键组成部分。结合USB话音系统的组成和信息流程，提出了一种基于全态模拟器的新型通信回路检测方法。通过全态模拟器构成的天地话音通信回路能很好的检测整个载人航天通信系统的工作情况，并且能单独的经常性的检测单个测控站话音系统的工作情况，以确保话音回路畅通无阻，为载人航天任务的顺利完成提供重要保障。

| Abstract: | Voice communication between the spacecraft and the ground is a key component of the manned space communi- cation system. Combined with the composition and the information flow of the USB voice system, a new method for voice communication loop detection is presented based on the full-state simulator. The air-to-ground voice communication loop based on the full-state simulator can well detect the working condition of voice communication in the manned space communication system, which can also detect the working condition of voice communication of a single tracking anc control station separately and frequently, ensuring the unimpeded voice communication loop and providing an important guarantee for the successful completion of the manned space missions. |
