一种可应用于载人航天器的无线话音通信系统

A Wireless Voice Communication System Applicable for Manned Spacecraft

面向未来空间站等大型载人航天器,传统的有线头戴式话音通信系统受电缆长度限制已无法满足航天员的应用需求;为进一步提高航天员在轨工作的方便性,提出了一种可应用于载人航天器的舱内无线话音通信系统,该系统通过设置蓝牙无线话音适配器的方式,在载人航天器现有话音系统的基础上实现了无线功能扩展;相关测试试验表明,该系统可支持多路无线话音通信,话音清晰可懂,且具备实时性高,操作简便等优点,可以满足航天员在轨话音通信使用需求。

For Large manned spacecraft,such as future space station,the traditional wired head voice communication system is unable to meet the application requirements of the astronauts due to the length limit of the cable.In order to improve the convenience of the astronauts in orbit,a wireless voice communication system in cabin for manned spacecraft is proposed,which realizes wireless function expansion on the basis of the existing voice system of the manned spacecraft by setting the Bluetooth wireless voice adapter.Test verifications show that the system can support multichannel wireless voice communication,clear voice can be heard through the system,and it has many advantages such as high real-time and easy operation.Astronauts’demands of voice communication on orbit can be satisfied by the wireless voice communication system.
